Description

Method and system for acquiring, controlling, operating and monitoring of elevator parameters

Technical field

The invention relates to the field of elevator technology, and is particularly suitable for elevators with counterweights. More specifically, it relates to a method and system for acquiring, controlling, operating, and monitoring elevator parameters.

Background technique

Elevator is an important type of personnel transportation equipment. It is used frequently and its safety and reliability are directly related to the safety of the occupants.

At present, in the elevator industry weighing application technology, it is often divided into the following three types of weighing schemes: A, B, and C;

A. Car inner sensor weighing: commonly used eddy current sensor, weighing pressure sensor, reed switch and other sensor weighing (such as the eddy current sensor to detect the shape of the car bottom to get the car's load), the structure of the car is usually double Layer structure, weighing rubber between the two layers of the car, material cost, installation cost, construction cost is high; and because the car bottom is a moving part, and the eddy current sensor is very sensitive to the distance, the weighing zero is easy to drift, the engineering staff Frequently re-adjusting the weighing zero, full load point and comfort, resulting in difficulty in maintenance and high cost.

B. Car outside sensor weighing: It is also possible to install a tension sensor on the top of the car and weigh it according to the output signal of the tension sensor; the European elevator also has a weighing method for installing the tension measuring instrument at the end of the traction rope, which needs to be A tension measuring instrument is installed on each wire rope; the Hitachi elevator adopts another technical scheme, and the traction rope is connected as a measured resistance in series to the impedance detecting sensor, and the impedance of the traction rope is measured and weighed; the scheme is not only There are shortcomings of high cost and single function, and there is no in-depth study on the shifting operation of the elevator. Because the elevator must enter the acceleration operation after starting, it must enter the deceleration operation when approaching the parking position, so the existing Class B technology can only be applied to In constant speed operation, it is inevitable to make mistakes during acceleration and deceleration, thus reducing the meaning of use;

C. Inverter weighing: Chinese patent application No. 201310116151.9 also proposes a method for judging the chaos in the elevator car. The torque calculation method for the torque of the motor at zero speed is proposed, m=(m3-m1 -T*I/R)/g; Due to the complicated mechanical mechanism/operation principle of the elevator, this calculation formula is not applicable when the elevator is running up and down.

Comprehensive analysis of existing technology: The existing measurement method of elevator operating parameters lacks wide applicability, which leads to the inconvenient and in-depth analysis of the elevator's operational safety status. It is not convenient to realize the operation before the elevator operating parameters do not exceed the safety limit threshold. The monitoring of the safe operation of the elevator is not convenient to achieve more advanced and efficient energy-saving control of the elevator.

detailed description

The first part of the content: For the nouns and parameters described in the technical solution of the present invention, the following explanations are given:

In the present invention, the data is the value, and the data is equivalent to the value; for example, the joint operation data is equivalent to the joint operation value, the measured value is equivalent to the measured data, the command value is equivalent to the command data, the preset data is the preset value, and the system preset data is That is, the system preset value, the manual preset data, that is, the manual preset value, the system default data, that is, the system default value, the fuzzy algorithm data, that is, the fuzzy algorithm value, the historical record data, that is, the historical record value, that is, the historical data, the historical value, etc.; In the present invention, the meaning of the direct combination of a plurality of well-known names is equivalent to the meaning of the connection of the words of the plurality of publicly-known words plus a "word", for example, the measured data is the measured data, and the preset data is preset. Data, etc.; the meaning of the direct combination of a non-public well-known word and a publicly-known word is equivalent to the meaning of the connection between the non-public-known word and the public-known word plus a "" word, for example: joint operation data, that is, joint operation data (ie, The data obtained through joint operations), the state of energy transfer, that is, the state of energy transfer, etc.; and so on, all nouns can be understood In this manner the reasoning income. The joint operation value is the estimated value, that is, the estimated value;

In the present invention, the calculation rule, that is, the rule, that is, the corresponding relationship, that is, the model, is a formula; in the present invention, it is equivalent to based on (that is, passing or passing); according to the data B setting data A or data A is set based on the data B, It can be any of the following cases: data B is directly set to data A, and data B is subjected to some additional processing (such as adding a certain offset value and multiplying a certain coefficient) into data A and the like;

In the present invention, the absolute value of the difference between A and B is smaller than the preset value. When the parameter types of A and B are different, the size of the preset value is different, and the size of the preset value can be reasonable through the system. Adjustment; A range is within B range: the upper limit of the A range is less than or equal to the upper limit of the B range, the lower limit of the A range is equal to the lower limit of the B range; the A range is out of range: The upper limit of the A range is greater than the upper limit of the B range, and/or: the lower limit of the A range is less than the lower limit of the B range; A is within the B range: the A is less than or equal to the upper limit of the B range , A is greater than or equal to the lower limit of the B range; A range is out of range: A is greater than the upper limit of the B range, and / or: A is less than the lower limit of the B range; in this paragraph, both A and B are one Code, which can be any parameter, data, value, etc.;

Analytical research of data: The data (ie, the value of a parameter) in the present invention usually has various attributes, such as a time attribute, an acquisition path, a value range, and the like;

Differentiating from the time attribute, the data (or the value of the parameter) can be divided into current data (ie, current value), historical data (ie, historical value), and predicted data (that is, predicted value, that is, data predicted based on a certain time point) That is, the future value); the current value is the real-time value when there is no limit; the historical data (or historical value) refers to the data generated in the past time point; the time of the data (or the value of the parameter), the priority refers to the data (or The generation (or generation) time of the parameter's value, not the priority value time;

Differentiating from the access route, the data (or the value of the parameter) can be divided into actual measurement, setting, and joint operation; the measured value can be called measured data (or measured value), and the set data is called setting data ( The data obtained by the joint operation (for example, calculated based on the energy balance of the elevator operation) is called joint operation data (or joint operation value); the setting data (or set value) can be divided into System setting data, manual setting data; system setting data is data that is not manually set.

The time of the integration time and the acquisition route, the data (or the value of the parameter) can be further divided into: the current measured data (or measured value), the current joint operation data (or joint operation value), the current setting data (or Fixed value), past measured data (or measured value), past preset data (or preset value), past joint operation data (or joint operation value), etc.; past joint operation data (or joint operation value) ) that is, the time-first joint operation data (or joint operation value);

Based on the knowledge of those skilled in the art or common sense courses: in actual applications (such as security monitoring), current measured data (or measured values), current joint operational data (or joint operational values) are common; and current Setting data (currently set by the machine or manually) for the current actual application is rare; setting data usually refers to the set data (such as data that has been set by the system, has been manually set) In addition to the explicit definition (for example, limited to "current" setting data), in the case of no limitation, the setting in the present invention means that the setting is preset, and the setting data is the set data. That is, the preset data (that is, the preset value); in the present invention, the past measured value, the past set value, and the past joint operation value belong to the set data for the current application, That is, preset data.

The preset data (or preset value) can be further divided into system preset data (ie, system preset value), manual preset data (ie, manual preset value), instruction data (or command value), and current running. Learning value; the manual preset data (or manual preset value) may also be referred to as manual input data (or manual input value); the learning value of the current running, referred to as the learning value;

The manual preset data (ie, the manual preset value, that is, the manual input value) refers to the value set by the elevator controller according to the actual situation;

The command data (ie, the command value is the command) may also be referred to as command preset data (or command preset value), with the control function of the parameter; for the mechanical operating parameters of the elevator (especially speed and / or acceleration) and / Control data (or command value) of data such as source dynamic parameters (eg, current or force or torque or power) used to control the mechanical operating parameters of the elevator (especially speed and / or acceleration) and / or source dynamic parameters Target data (or target value) of parameters such as current or force or torque or power; if the current speed is 1M/S, when the system issues command data (or command value) of 2M/S speed, the elevator needs an acceleration. The process can reach the target speed;

The learning value of the secondary operation generally refers to the value obtained by performing the energy balance calculation of the elevator operation according to the set condition in the current running process, and the present invention obtains the energy balance calculation of the elevator operation according to the setting condition. The joint operation value means that the joint operation value is calculated by performing the elevator operation energy balance in advance, and therefore can also be understood as being obtained according to the joint operation value obtained in advance;

The system preset data (that is, the system preset value) includes the history value, the fuzzy algorithm value, and the system default value.

Historical value, general noun; usually refers to the value of the learned record that has been experienced by going through; the historical record value, including the original value of the historical record, the actual value of the historical record, the value of the historical record correlation factor, etc., the specific formation method is described later. Said

The fuzzy algorithm value refers to the value obtained by the set fuzzy algorithm rule (see the following for details);

The system default value is the simplest data setting method. Obviously, the system default (accurate) value; the system default value can include the factory default value, the corrected or adjusted default value; the factory default value is also the factory default. Value, original value; In general, system defaults can be applied more widely than factory defaults;

The measured data (or measured value) is relatively easy to understand, and refers to the value measured based on the sensor (or hardware facility, instrument, etc.); in the present invention, the actual measurement is the measurement, that is, the detection; for example, the current value measured by the current sensor, such as a speed measuring instrument. Measuring the obtained elevator speed, such as the acceleration measured by the acceleration sensor, such as the mass or weight value measured by the load cell, etc.; the value of the position and velocity measured based on the information of the satellite navigation system (such as Beidou or GPS) is also The measured value, the satellite navigation system (such as Beidou or GPS) information can understand a kind of radio positioning, measurement information. The data obtained from the measured data and then calculated by conventional calculations is called the measured value, which is also the measured value; for example, the torque T is measured first, and then the force is divided by the radius. The force is also called the measured value; special statement: based on the part The measured data (for example, the source dynamic parameter) is further calculated by the energy balance calculation of the elevator operation (this method is the core point of the invention), and is not a measured value, which belongs to the joint operation value;

Distinguishing from the value range, the data (or the value of the parameter) can be divided into a maximum value (ie, an upper limit value), a minimum value (ie, a lower limit value), an intermediate value, or a center value;

Distinguish from the nature of the data, the data can be divided into actual value, instruction data (or instruction value), reasonable range (including reasonable value), safety range (safety value), special meaning value, etc.; because the instruction data (or instruction value) is Security has a special meaning, and it is also allowed to be drawn from the preset data as an independent data type;

It is understood by common knowledge known to those skilled in the art, or based on the main content of the present invention: the actual value and the true value of the present invention are different concepts; the real value is usually a natural and true value of a certain attribute of a certain parameter. For example, the quality of an empty car of an elevator is 500KG, the mass of goods carried is 150KG (for example, 150KG for two people), the true value of the total mass of the elevator car is 650KG; if the total mass of the elevator car is set at a certain time The actual value (such as manual input, or an elevator operation energy balance calculation), due to understandable error, accuracy and other factors, the actual value of the total mass of the elevator car is likely to be set to 680KG, then the 680KG can be regarded as The actual value of the total mass of the elevator car at the time of setting (but not the actual value); the actual value is an actual operational data in the present invention, and the actual value is naturally set with the setting time and setting mode of the parameter. , setting accuracy and other factors related; in the absence of a limited description, the actual value of the parameter in this paper refers to the value close to or equal to the true value when the parameter is set; for example, when the actual value is the root When the preset value is set, the actual value is the actual value of the parameter at the preset time; for example, when the actual value of the parameter is set according to the system default value in the preset value, the actual value is also the parameter. The actual value (that is, the calibration value) in the system default (usually the standard state); for example, when the actual value is set based on the learning mode, the actual value is the actual value at the time of learning. (that is, the learning value); if there is no limit description, the actual value means that the parameter is obtained in a practical application (for example, in any acquisition method, measurement method, monitoring method, monitoring method or processing method in the present invention) Enter the actual value of the current state of the acquisition time of the value of the parameter, ie the current value of the parameter. In the present invention, when there is no limitation, the current or current time refers to obtaining the value of the input parameter in a practical application (for example, in any acquisition method, measurement method, monitoring method, monitoring method or processing method in the present invention). In the present invention, the actual value of the parameter is the current actual value of the parameter without any limitation; when there is no limit, the current value of the parameter is also the current actual value of the parameter.

In the present invention, any scheme or data can be equivalently substituted into other technical solutions; any of the formulas in the present invention can be arbitrarily modified. Move any parameter in the formula to the left of the formula equal sign as the target parameter (or measurement object), and put other parameters equivalent to the right to calculate the target parameter (or measurement object); Equivalent deformation;

An acceptable range of parameters (ie, a reasonable range) means that the parameter can achieve a useful value or a range of natural attributes of the parameter (including the input parameter); the acceptable range described in the present invention can be The third range may also be the fourth range or the second range (ie, the permission deviation range), depending on the application; for example, the energy transmission amount status identification, the elevator energy transmission amount abnormality monitoring, reflection, Analyze any one or more of the operating conditions (wear and/or safety conditions) of the power transmission components to be monitored of the elevator, the monitoring of data related to elevator operation safety, and the processing of data related to elevator operation safety, a use of practical value; the scope of the invention is an acceptable range (ie, a reasonable range) without limitation

From the value range analysis, generally, the third range is within the fourth range; the first permission range may be simply referred to as the first range, which is the reference value + the license deviation range; the second range is a proposed by the present invention. A range of special significance, that is, a permissible deviation, which can be used to identify the condition of the energy transfer; when a parameter is a parameter to be measured (ie, a parameter can be changed), the second range of the parameter can be related to the actual value of the parameter. The value changes normally and floats, even with the actual value and the curve floats; it can be within the third range or beyond the third range; its absolute value can be much smaller than the absolute value of the fourth range, in some special occasions The time may also be greater than the absolute value of the fourth range; when a parameter is a preset parameter or a system inherent parameter, the second range of the parameter may coincide with the acceptable range or may be within an acceptable range;

Obviously, any one or more of the first range, the second range, the third range, the fourth range, and the acceptable range of the elevator operating parameters may be preset, and may be preset values (especially system presets) Value, secondly, can also be manually entered); any parameter can be The standard value, the third range, and the fourth range are preset; for example, the standard value of the gravitational acceleration g can be preset to 9.81; the third range of the gravitational acceleration g can be preset to (9.5 to `10.5), and the gravitational acceleration g The fourth range can be preset to (8.5 ~ `11.5), and so on; and any of the standard value, the third range, and the fourth range of any parameter can be preset and adjusted according to the scene situation and the actual situation.

All of the parameters or data or solutions that are not explained in detail in the present invention can be reasonably explained, described, and summarized by the technical solutions or concepts provided by the present invention; and can be combined with the prior art and common knowledge.

Knowing in any one or more ways of the technology; the user can also operate the elevator to test, verify, adjust, and set; for example, the deviation of the preset data (that is, the preset value (especially the system preset value)) Even the error causes the monitoring effect of the monitoring method to decrease, and does not affect the effectiveness of the technical solution; in the present invention, the setting is preset;

It will be apparent that the operation of the present invention primarily refers to the operation of the elevator car in the vertical direction.

The invention can measure parameters, that is, parameters that can be measured, generally refers to the value of the parameter in the elevator operation can be obtained by the measured way; the unmeasurable parameter of the invention is the unmeasurable parameter, generally refers to the value of the parameter in the elevator operation cannot be Measured or unmeasurable, determined by the hardware condition of the elevator; if the sensor that can measure the parameter is not set, or the sensor is not working properly, it is untestable; the high-configuration, high-performance elevator naturally measurable parameter More; low-profile, low-cost elevators can be set with fewer sensors; typically, speed, source dynamics, and vertical acceleration are all measurable parameters; most system-specific parameters, such as empty car mass M0, efficiency coefficient, traction wheel radius, mechanical transmission system efficiency coefficient Km is usually unmeasurable in operation; the value of unmeasurable parameters can usually only be preset or calculated by elevator running energy balance.

The preset parameter of the present invention means that when the elevator is working normally, the absolute value of the difference between the maximum value and the minimum value of the parameter is within a preset range, that is, the value of the parameter obtained based on the preset and the parameter. The difference of the current value is within a predetermined reasonable (or prescribed) range, that is, the value of the parameter obtained based on the preset can be used to describe the true condition of the parameter; for example, the empty car mass m0, the efficiency coefficient, The rolling resistance coefficient, the integrated gear ratio im, the gravitational acceleration, the traction wheel radius, etc. are all preset parameters; in general, the value of the preset parameter can be set based on a preset value, which is usually a calibration value. If the radius of the traction sheave, the calibration value can be the preset value of the elevator factory; the calibration value of gravity acceleration and the radius of the traction sheave is equal to the preset value when the elevator leaves the factory; the calibration value of the rolling resistance coefficient is equal to the type The traction sheave and the guide wheel bear the theoretical value of the gravity of the car and the counterweight. The calibration value can be a fixed value or a variable function value, such as the efficiency coefficient described above, which is a function that gradually decreases as time and/or total elevator operating time changes.

The parameter to be measured according to the present invention means that at a certain moment when the elevator is working normally, the difference between the value of the parameter obtained based on the preset and the current value of the parameter exceeds a preset reasonable (or prescribed) range, That is, the value of the parameter obtained based on the preset cannot be used to describe the true state of the parameter, and cannot be used normally, that is, the current value of the parameter cannot be obtained by a preset manner, and the parameter is an unpredeterminable parameter; For example, the source dynamic parameters, speed, and acceleration belong to the parameters to be measured; the parameters to be measured can also be understood as variable parameters. When the elevator is working normally, the absolute value of the difference between the maximum value and the minimum value of the parameter is preset. Outside the range; the preset range can be adjusted by the user or the manufacturer, that is, the manufacturer or the user can freely select the number of parameters to be measured, and the more the parameter to be measured The acquisition accuracy of many parameters is improved; the more preset parameters can reduce the cost; in general, the values of the parameters to be measured and the measurable parameters are obtained based on the measured values of the sensors.

The method of obtaining the electrical auxiliary parameter value is as follows: reading the internal parameters of the motor driver and obtaining;

2.2. Detailed description of the dynamic parameters of the traction parts of the elevator:

2.1.1. The traction component of the elevator is usually a steel wire rope. The dynamic parameters of the traction component mainly include the comprehensive pulling force F1 of the vertical running of the traction car on the steel wire rope; the comprehensive tensile force F1 is usually measured by a tensile force sensor, which is installed on the passenger car. The hook of the car can also be installed at the connection with the wire rope and the hook; the tension sensor can be either an integral tension sensor corresponding to all the wire ropes; or a tension sensor can be provided for each wire rope. Then the signals of the respective wire rope tension sensors are added to obtain a comprehensive pulling force F1;

The tension sensor can also be set at some other position (such as the support of the guide wheel above the elevator shaft). The tension of the tension sensor is used to obtain the comprehensive tension F2, and then the integrated tension F1 is calculated according to the angle of the F2 and the wire rope; the tension sensor It can be a whole tension sensor corresponding to all the wire ropes, or a tension sensor can be provided for each wire rope, and then the signals of the respective wire rope tension sensors are added to obtain a comprehensive tension F2;

Pull force F1 or comprehensive tension F2;

2.3. Detailed description of the dynamic parameters of the mechanical rotating parts of the elevator:

The dynamic parameters of the mechanical rotating member mainly include the source dynamic parameters obtained on the mechanical components of the rear end of the motor (the motor output shaft, the traction sheave, and the intermediate mechanical transmission component between the motor output shaft and the traction sheave, etc.); The dynamic parameters of the mechanical rotating part mainly include the mechanical torque, which can be measured by a torque sensor mounted on a rotating part at the rear end of the motor, so the dynamic parameter can also be called the source dynamic parameter of the rear end; of course, relative to the foregoing The total tensile force F1 is measured by the tension sensor or the tension sensor, and the cost of measuring the torque with the torque sensor is greatly increased; especially compared with the measurement cost of the electric power parameter, the measurement cost of the torque sensor is greatly increased, so practical Relatively lower in sex, but still creative and practical compared to the prior art for the safety monitoring of elevators and the control of energy-efficient operation.

Further, according to the strong correlation with the power system, the source dynamic parameters can be divided into the source dynamics that are strongly related to the power system. Number, source power parameters that are weakly related to the power system; generally, the source power parameters of the motor and motor front end (including power supply devices, motor drives, etc.) can be classified as source power strongly related to the power system. Parameters; for example, three source dynamic parameters of electrical power, electromagnetic torque, and current, and electromechanical combined parameters obtained from three source dynamic parameters are all source dynamic parameters that are strongly related to the power system.

Of course, the strong correlation with the power system is a relative concept;

For example: when accelerating the ascent, when moving at a constant speed, when moving at a constant speed, the dynamic parameters of the traction member (such as the pulling force F1) and the dynamic parameters of the mechanical rotating member (such as T1, etc.); because the nature of the source dynamic parameters is mainly used to describe the power The force or torque that the system needs to generate to overcome the self-weight and acceleration of the carrying mass; at this time, the source dynamic parameters can be classified into source dynamic parameters that are strongly related to the power system.

For example, in the first embodiment of the monitoring method (#3) described later, the power parameter (such as the pulling force F1) of the traction member when decelerating downward or the dynamic parameter (such as T1, etc.) of the mechanical rotating member calculated according to F1 and R1 is because At this time, the nature of the source dynamic parameters is mainly used to describe the force or torque generated by the self-weight and acceleration of the carrying mass; at this time, the source dynamic parameters can be classified into the source-dynamic parameters of the weak correlation of the power system; and generally speaking The root cause of the acceleration signal, that is, the acceleration and deceleration, is derived from the control of the power system.

3. The elevator quality according to the present invention refers to parameters related to at least one of the carrying quality, the counterweight mass, and the empty car quality, including directly related and/or indirectly related parameters; the mass unit can be used in kilograms (KG or Kg) indicates; direct correlation means that the above three parameters are directly used as measurement objects or input parameters, and indirect correlation refers to the quality obtained by deforming the above three parameters, but the essence of the implementation of the scheme is the above three parameters, such as The above three qualities may be respectively equivalent to the sum of the respective parts, and the sum of the parts thereof may be used as a measurement object or an input parameter, or the mass of a part of one of the above three parameters may be used as a measurement object (ie, Part of the mass = a certain mass - the mass of the other part, at which time the mass of the other part is known).

3.1. The carrying quality of the present invention is any one or two parameters of the mass of the carrying item m1 and the total mass m2 of the elevator car; the total mass m2 of the elevator car refers to the mass m1 of the carrying item and the mass m0 of the empty car at the same time. Data; the mass of the carried item m1 refers to the quality of the personnel loaded outside the net weight of the empty car; the national standard stipulates that the passenger lift is calculated according to 75kg per person, and the number of passengers in the elevator can be calculated according to m1;

3.2. Calculation of the total mass m2 of the elevator car: m2=m0+m1;

3.3, no-load car mass m0, counterweight mass m3 can be accurately learned by manufacturer parameters, or weighing scales, no need to measure; the quality of traction parts (such as wire rope) is usually negligible; traction parts (such as wire rope) The mass is included in the no-load car mass m0 and/or the counterweight mass m3; when the no-load car and the counterweight are in the same horizontal position, the no-load car mass m0 and the counterweight mass m3 each contain half the wire rope mass When the car is at the top/counter weight at the bottom, the counterweight mass m3 contains the mass of most of the wire rope; when the car is at the bottom/counterweight at the top, the car mass m0 contains the mass of most of the wire rope; The mass m0 and the counterweight mass m3 may also include the quality of the respective compensation ropes;

It can be seen that the quality of the ropes contained in the no-load car mass m0 and the counterweight mass m3 is related to the position. The function of the no-load car mass m0 and the counterweight mass m3 and the position can be set, which can be relatively accurate by theoretical calculation or actual measurement. Know the quality of the empty car The mass of the wire rope contained in each of m0 and counterweight mass m3;

4. The operating parameters of the system according to the present invention refer to parameters other than elevator mass and source dynamic parameters in the elevator operating parameters, including any one or two parameters of mechanical operating parameters and system inherent parameters.

4.1. The mechanical operating parameters of the present invention mainly include, but are not limited to, the following parameters: speed Vq, acceleration aj, wind resistance fw, angular acceleration β of the internal integrated rotating rigid body, and the like.

4.1.1 The speed Vq according to the present invention refers to the speed of the vertical displacement of the elevator car; and includes any one or two parameters of the uplink speed V1 and the downlink speed V2; the speed value is obtained in the following manners:

Vq value acquisition mode 1: directly obtain the Vq value by the speed sensor measurement set on the car; the Vq unit can be expressed in meters per second (m/s);

Vq value acquisition mode 2: Indirectly obtain the Vq value by measuring the motor speed n1: the calculation formula for reference is as follows: Vq=(2π*n1/im)*R1/60; this method is not accurate when the elevator wire rope is slipping;

All speed-related parameters can be used to obtain the Vq value; such as the motor drive operating frequency FR (for example, the rated frequency of the frequency converter usually corresponds to the rated speed of the motor), the gear speed, the intermediate rotating angular velocity, the intermediate transmission Line speed;

Vq value acquisition method 3: Indirectly obtain the Vq value by the acceleration aj; the calculation formula for reference is as follows: Vq_1=Vq_0+aj*t; t is the unit time, Vq_0 is the Vq value of the previous time period, and Vq_1 is the speed of the current period Vq value;

4.1.2, the acceleration aj (also denoted by a or acc) of the present invention, refers to the acceleration of the vertical displacement of the elevator car;

Through in-depth analysis of the structure of the elevator, because the car and the counterweight are connected by a flexible traction member (such as a wire rope) instead of a rigid connection, the parameter design principle of the rotating rigid body cannot be directly applied, and the car acceleration aj and the counterweight acceleration ad may be equal. May not equal; the weight acceleration ad can be measured and calculated separately; in the simplified calculation, the car acceleration aj is equal to the counterweight acceleration ad;

For ease of description and understanding by the skilled person in the art, the invention stipulates that the value of the acceleration can be positive or negative; the direction of the speed can be set to a positive value regardless of the elevator ascending or the elevator descending; when the absolute value of the speed increases, this The acceleration is positive, and the acceleration is positive; when the absolute value of the velocity decreases, the acceleration is negative, and the acceleration is negative; of course, the user is allowed to define acceleration, velocity, and source in other and more complicated ways. Positive and negative of the power parameters.

There are several ways to obtain the acceleration aj:

Aj value acquisition mode 2: obtained by indirect measurement of motor speed n1, or speed Vq; the calculation formula for reference is as follows: aj=(Vq_1-Vq_0)/t, aj=dVq/dt; acceleration is the differential of speed versus time ;

4.1.4. The acquisition of wind resistance fw can be as follows:

Fw value acquisition method 1: first obtain the speed Vq of the elevator and then obtain the fw value by calculation; the calculation formula for reference is as follows: fw=(1/2)*C _d *(p0*A ₀ *(Vq) ² ); C _d is the drag coefficient of the elevator, p0 is the air density, A ₀ is the windward area of the elevator; C _d , p0, A ₀ are all inherent parameters of the system, which can be obtained by reading the preset value of the system; Obtaining the wind resistance fw has the advantages of low cost and simplicity;

Fw value acquisition mode 2: preset an association table of elevator speed and wind resistance fw value, and when the elevator is running, the corresponding wind resistance fw value is obtained by looking up the speed value table;

4.1.6. The angular acceleration of the internal integrated rotating rigid body β: The internal comprehensive rotating rigid body refers to all the rigid mechanical rotating parts in the elevator internal transmission system. The β parameter can be obtained by the speed sensor or by first obtaining the motor speed n1. Or the speed Vq of the elevator or the acceleration aj of the elevator is calculated and obtained;

4.2. The system inherent parameter of the present invention refers to a parameter caused by an elevator or an inherent property of the environment, and the inherent parameter of the system of the present invention may also be referred to as a system setting parameter;

4.2.1. Common system intrinsic parameters include, but are not limited to, the following: rolling frictional resistance coefficient μ1, frictional force f0 of the rail and the car in the elevator shaft, the integrated gear ratio im, the rear gear ratio im3, the traction Wheel radius R1 (also denoted by R), conversion coefficient Ki of torque current and electromagnetic torque, conversion coefficient Ko of motor current active component and electromagnetic torque, efficiency coefficient Km of mechanical transmission system, efficiency coefficient Kea of electric power system , the efficiency coefficient Km3 at the back end, the moment of inertia L0 of the internal integrated rotating rigid body, the drag coefficient C _d (also denoted by Cd), the air density p0, the windward area A ₀ (also denoted by S), and the gravitational acceleration g (also called It is a gravity acceleration factor, its meaning and value 9.8 are all known techniques, basic physical common sense, and the preset time range of parameter values.

A detailed description of the system's inherent parameters is as follows:

4.2.2, the efficiency coefficient of the electric power system Kea, the efficiency coefficient of the mechanical transmission system Km:

4.2.2.1. The efficiency coefficient of the electric power system Kea includes and is not limited to the following parameters:

The efficiency coefficient of the motor Ke: refers to the ratio of the electrical power of the motor to the mechanical power output of the motor shaft, that is, the conversion efficiency; the Ke value may be different in view of the electric state and the motor braking state; the efficiency coefficient of the motor in the electric state is named For Ke1, the efficiency coefficient of the motor in the motor braking state is named Ke2; the efficiency coefficient of the permanent magnet synchronous motor is high, which can reach 95%; the efficiency of the AC asynchronous motor is low, about 90%;

Motor drive to motor efficiency coefficient k21: refers to the ratio of the input power of the motor driver to the electrical power of the motor when the operating condition of the motor is the electric state, that is, the conversion efficiency; it can also refer to the ratio of the output power of the power supply to the electrical power of the motor. That is, conversion efficiency;

The power factor to motor efficiency coefficient k31: refers to the ratio of the input power of the power source to the electrical power of the motor when the operating condition of the motor is the electric state, that is, the conversion efficiency;

The efficiency coefficient of the motor braking power to the power supply k14: the ratio of the motor braking power to the power fed back to the power supply device, that is, the efficiency coefficient;

4.2.2.2, the efficiency coefficient Km of the mechanical transmission system, also referred to as mechanical transmission system efficiency: refers to the motor output shaft including the elevator, the traction sheave, and the intermediate transmission components between the motor output shaft and the traction sheave. The efficiency coefficient of the integrated transmission; in order to cope with the possible fluctuation of the Km value in different speed intervals, a one-dimensional function, Km(Vq), may be set, that is, according to different speed intervals (eg Zero speed, low speed, high speed) take the corresponding Km value; the Km value may be different in view of the electric state and the motor braking state; the efficiency coefficient of the mechanical transmission system in the electric state is named Km1, and the motor is braked. The efficiency coefficient of the mechanical transmission system is named Km2;

When the traction machine of the elevator is a permanent magnet synchronous toothless traction machine, the efficiency coefficient Km of the mechanical transmission system is high, and may be higher than 90%;

When the traction machine of the elevator is a turbo traction machine, the efficiency coefficient Km of the mechanical transmission system is low, and when the motor driving the traction machine is in the electric state, it is only about 70%, and the energy is usually from the worm. Passed to the turbine; when the motor driving the traction machine is in the motor braking state, it is only about lower, because the rotation of the turbine is difficult to drive the rotation of the worm, only a small part of the braking energy can be fed back to the motor and the power grid;

The comprehensive efficiency coefficient Kem of electromechanical transmission can also be called the comprehensive efficiency Kem of electromechanical transmission; Kem contains the efficiency coefficient Ke of the motor, including the efficiency coefficient Km of the mechanical transmission system; Kem=Ke*Km, Kem1=Ke1*Km1, Kem2= Ke2*Km2;

4.2.2.4, the relevant efficiency coefficient k31, k21, k14, Ke, Km value is basically constant within a certain speed and load interval;

The change of k31, k21, k14 value means that the internal rectifier bridge of the power supply or the motor driver, the IGBT may have a short circuit, or an open circuit, parameter variation and other abnormal conditions; the change of the Ke value means that the internal rotating magnetic field parameter variation of the motor or the motor winding is short-circuited, or Variations that may cause serious consequences, such as a broken circuit;

The current, voltage and speed torque of the elevator can be changed, but the basic values of k31, k21, k14, and Ke cannot be changed; therefore, the above k31, k21, k14, and Ke values are not only used as the efficiency coefficient of the electric power system, but also as the electric power. An important basis for the security status of the system;

The change in the efficiency coefficient Km of the mechanical transmission system may represent severe wear and tear in the mechanical transmission system of the elevator including the motor output shaft, the traction sheave, and the intermediate transmission component between the motor output shaft and the traction sheave, or Variations that may cause serious consequences, such as deformation or gear embrittlement;

The mechanical torque speed of the elevator can be changed, and even the frictional force can vary with the size of the load, but the basic Km value cannot be changed greatly, or it may be a serious fault; therefore, the Km value can be used not only as the efficiency of the mechanical transmission component. The coefficient can also be used as an important basis for the safety condition of mechanical transmission components;

By directly monitoring the k31, k21, k14, and Ke values as the measurement objects, or by indirectly monitoring the k31, k21, k14, and Ke values by calculating the joint operation values of other measurement objects (such as the carrier quality), the elevator can be effectively monitored. The operating conditions of the electrical power system;

It is also possible to set the comprehensive efficiency coefficient Keem of the electric power system of an elevator, which includes the efficiency coefficient Km of the mechanical transmission system and the efficiency coefficient Kea of the electric power system; the Keem value is the Km value of the elevator and the efficiency coefficient value of the electric power system Kea Product of

Any source power parameter of the elevator may be set to indicate the energy and/or power transmission efficiency of the source power parameter and the force (ie, power) driving the elevator to operate vertically, which may be represented by Ka; the transmission efficiency may be referred to as efficiency Coefficient; based on source dynamic parameters and efficiency The rate coefficient calculates the power of the elevator; for example, when the source power parameter is a detectable force, the power = the value of the source power parameter *Ka; for example, when the source power parameter is a detectable torque, the power = Ka * The value of the source dynamic parameter /R, R is the actual radius or equivalent radius at which the torque is converted into power; for example, when the source dynamic parameter is detectable power, the power = Ka * the value of the source dynamic parameter / V, V is the running speed of the elevator; the calculation formula of the power can be used for the calculation of the energy balance of the elevator operation; the Ka value can be known by a combination of a type test, a limited number of manual trials, and other prior art. From another perspective, the efficiency coefficient Ka:

Obviously, in the present invention, in the absence of the definitions of the front and the rear, the efficiency coefficient: the power component and/or the transmission between the signal collection point of the source power parameter and the action point of the force (ie, the power) driving the vertical operation of the elevator. The energy and/or power transfer efficiency of the component, that is, the overall efficiency coefficient; the power component and/or the transmission component is referred to as the power transmission component to be monitored; based on the common knowledge of those skilled in the art, the point of action of the power Preferably, it is the equivalent centroid of the elevator car, as shown in Figure 3, Figure 4, point O; the power transmission component to be monitored, including the power system (usually an electric power system) after the signal acquisition point of the source power parameter, mechanical transmission The system, the contact surface of the car and the guide rail, etc.; the efficiency coefficient is also the energy and/or power transmission efficiency of the power transmission component to be monitored; because of the energy conservation principle, if the efficiency coefficient is lowered, it means the power to be monitored The energy transmission efficiency of the transmission component is reduced, that is, the internal loss is increased, the internal resistance or the resistance is increased, the heat is increased, and the safety condition is deteriorated. The risk of failure of the power transmitting member to be monitored is increased; therefore may be used to reflect the efficiency coefficient, analysis of power transmission member operating conditions to be monitored elevator, especially of the operating condition of wear and / or safety conditions. Generally, the signal acquisition point of the source power parameter can be moved to the signal point in the front of the power system as much as possible, and the energy balance calculation of the elevator can be used to monitor and protect a wider range of power components.

In general, when the motor of the elevator is a permanent magnet synchronous motor and the traction machine is a toothless traction machine, the overall efficiency coefficient of the elevator will be as high as 90%; and regardless of whether the motor is in an electric state or a motor braking state, the elevator The overall efficiency coefficient is relatively high;

When the traction machine of the elevator is a turbo traction machine, the overall efficiency coefficient is only about 70% when the motor driving the traction machine is in the electric state due to the low efficiency coefficient Km of the mechanical transmission system; When the motor of the elevator is an AC asynchronous motor, the overall efficiency coefficient is lower; when the motor driving the traction machine is in the motor braking state, the overall efficiency coefficient is only about lower, and only a small part of the energy can be fed back to the motor and the power grid. At this time, the energy balance calculation of the elevator operation is performed, and the linearity of the correspondence between the quality of the carried goods of the elevator and the source dynamic parameters is not good.

4.2.3. Rolling friction resistance coefficient μ1, that is, rolling resistance coefficient μ1: Because of the structural characteristics of the elevator, the traction sheave and the guide wheel bear the pressure generated by the gravity of the car and the counterweight; therefore, the rolling friction coefficient of the elevator is μ1 (along with The rolling frictional resistance fr) is mainly the data of the traction sheave and the guide wheel component;

4.2.4. Integrated transmission ratio im: refers to the comprehensive transmission ratio including the motor output shaft, the traction sheave and the intermediate transmission component between the motor output shaft and the traction sheave; the efficiency coefficient Km of the mechanical transmission system usually refers to the motor to the traction The efficiency coefficient of the transmission system between the wheels; because the source power parameter of the present invention includes the source dynamic parameters of the rear end, the corresponding transmission ratio and efficiency coefficient need to be set; and the parameters of the source dynamic parameters of the rear end are taken to the traction sheave The transmission ratio between them is called the transmission ratio im3 of the rear end, and the efficiency coefficient between the parameter points of the source dynamic parameters of the rear end to the traction sheave is called the efficiency coefficient Km3 of the rear end;

The transmission ratio im and im3 of the elevator are usually a fixed value; if the values of im and im3 are variable, it needs to be centrally controlled during the calculation. Given the current value;

4.2.5. The frictional force f0 between the object and the car in the guide rail and/or the elevator shaft is the core information of the safe operation of the elevator. It is a technical point neglected by the prior art. In recent years, many passengers have been caught in the car. The serious safety accident causing death of the person between the car and the elevator shaft is that the elevator does not fully consider the measurement and abnormal monitoring of the friction force f0 during the safety design; the technical solution provided by the present invention is to measure the friction force f0 High-precision/high-sensitivity measurement and energy transmission status monitoring of the joint calculation values of objects, or other measurement objects (such as the carrying quality of the elevator), so that real-time direct or indirect measurement and monitoring friction during elevator operation The value of the force f0, when the frictional force f0 (or the deviation value of other measuring objects) exceeds the preset safety value, the corresponding safety processing mechanism is started (such as shutdown, or even reverse running a set distance such as 10 cm), then It helps to prevent serious safety accidents that result in death of a person (the occupant is stuck between the car and the elevator shaft). When f0 is used as an input parameter, the preset value is generally taken, and is preferably a preset actual value; since f0 is generally small, f0 may take a value of 0 as an input parameter.

4.2.7. The values of the inherent parameters of the system generally have preset values, especially the system preset values; the preset values can be given by the central controller of the elevator, and the correctness of the system's inherent parameters and system preset values is also determined by The central controller of the elevator is guaranteed; the preset value of the system can be known by the elevator production service manufacturer and the professional testing organization; the user can also test, verify, adjust and set it by himself; for example, self-learning of the hoistway parameters, learning in the process of elevator going up and down Related parameters (especially the values of f0, μ1, Kem and other parameters at different positions and different speeds). If the deviation of the system preset value of the parameter or even the error causes the monitoring effect of the method or system of the present invention to decrease, the effectiveness of the technical solution is not affected.

5. Explanation of source power combination parameters:

The power refers especially to electrical power; the electromechanical combination parameter is a typical source dynamic parameter, and its type still belongs to the electrical power parameter;

An example of a typical electromechanical combination parameter is as follows: ((Ke*Km)*(Po/Vq) represents a driving force calculated according to the motor power; eg (Te*im/R) represents a calculation based on the electromagnetic torque Te The driving force, such as (Te*n1/9.55/Vq), represents another driving force calculated based on the motor power, which is calculated by torque and speed;

6.2. Quality combination parameters are also classified into elevator quality; (m1+m0), (m2-m0), (m1+m0+m3), etc. are all elevator quality; such as (m2*g), (m1*g) Although the parameters become the gravity that the object bears, it is still classified in the elevator quality in the present invention.

6.3. When two or more system intrinsic parameters are combined into one calculation formula (such as ((Ke*Km)*(im/R)), or (im/R), etc.), the calculation formula is still classified in the system. Inherent parameters.

7. Elevator operating parameters: Obviously, all parameters that affect the operating state of the elevator, or all parameters related to elevator operation, can be referred to as elevator operating parameters; the source dynamic parameters, elevator quality, system described in the present invention The operating parameters (including the mechanical operating parameters and the system inherent parameters) constitute the operating parameters of the elevator;

7.1. Derived parameters: Any parameters described in the present invention are derived, deformed, renamed, expanded, reduced, increased offset, filtered, weighted, averaged, estimated interference, compensated for interference, processed by RLS algorithm, recursive The parameters obtained by the least squares processing and the like are referred to as derived parameters of the parameters, and all the derived parameters still belong to the original parameter type;

7.2. The energy transfer condition correlation factor according to the present invention refers to a parameter directly or indirectly related to the energy transfer status judgment of the elevator, which includes the condition information of the elevator, the load condition information, the position information, the elevator quality, and the source. Any one or more of the dynamic parameters and the operating parameters of the system; the condition of the machine according to the present invention mainly refers to the condition of the elevator power system and the transmission system, such as good mechanical parts of the elevator, good lubrication, and small wear condition, the condition of the machine is good. If the elevator wears seriously, the condition of the machine is good and the index is low; the load condition mainly refers to the condition of the elevator loader or the item, such as the frequent jumping of the personnel in the elevator or the arbitrary rolling of the article, the good condition of the load condition is low; the position of the invention Information can be obtained according to the encoder, limiter measurement, etc.

7.3. The safety limit threshold of elevator operating parameters can be divided into fixed safety limit thresholds and safety limit thresholds of active parameters;

7.3.1. Fixed safety limit The threshold is usually the safety value of the elevator operating parameters to avoid damage to the device according to the electrical system and/or mechanical system design specifications of the elevator: such as the current safety value of the motor Io_ena, the voltage safety of the motor Value Uo_ena, electromagnetic torque safety value Te_ena, power safety value Po_ena of the motor (usually equal to the rated power of the motor), safety value P4_ena for power generation feedback braking power, safety value P5_ena for energy consumption braking power, elevator Rated load capacity m1_ena (also known as rated load or rated load, etc., in kilograms/kg);

7.3.2. The safety limit threshold of the activity parameter usually refers to the permissible value of the mechanical operation parameter that can be adjusted according to the operating conditions of the elevator (such as the quality of the carried goods, the flow of energy to the working condition, etc.), such as the allowable value of the upstream speed V1_ena, The allowable value of the downlink speed V2_ena, the absolute value of the permissible value of the accelerating acceleration in the ascending acceleration aj1_ena, the absolute value of the permissible value of the accelerating acceleration at the deceleration ascending aj3_ena, the absolute value of the permissible value of the accelerating acceleration in the downward direction aj2_ena, and the permissible value of the acceleration in the decelerating downward The absolute value of aj4_ena, etc.; the invention will accelerate the ascending, decelerating up, accelerating down, decelerating down and other states are called the fast change direction;

The safety value of the elevator operating parameters can be further subdivided into instantaneous working safety values, long-term continuous working safety values, and the like.

8. Description of the "elevator lifting operation" described in the present invention:

8.1. Convention of the Invention: The "elevator lifting operation" described in the present invention is equivalent to "elevator operation" is equivalent to "operation", both refer to The elevator runs up and down in the vertical direction; "Elevator lift operation" defaults to the command that the brake system of the elevator has issued a brake release (including rigid release, flexible release, etc.), and other mechanical brake systems have been issued. The command of mechanical brake release; "Elevator lift operation" usually does not include all the "elevator non-lifting operation" time period of the elevator door opening and closing action, stop, brake, etc.; because it is not convenient when "elevator non-lifting operation" The operation of the elevator is monitored by collecting electrical power parameters and calculations.

The elevator lifting operation of the invention comprises two states of zero speed running and non-zero speed running;

The non-zero speed operation of the present invention includes a variable speed operation and a non-zero constant speed operation; wherein the variable speed operation includes an acceleration operation and a deceleration operation;

8.2. “Elevator lift operation” status or “Elevator non-lift operation” status can be identified and given by the central controller of the elevator; the motor drive operation status word or motor drive control command word can also be obtained to identify and judge the motor. "Forward or reverse or stop" status.

8.3. The invention provides a monitoring method for elevator lifting operation, and the “elevator running and running” may have a starting point and an ending point in time;

It can be set from the state of “elevator non-lifting operation” to the “elevator lifting operation” state. As the starting point of the time period of this “elevator lifting operation”, the typical starting point is the brake release, which means a new “elevator” The beginning of the time period of "lifting operation"; can be set from the "elevator lift operation" to the "elevator non-lifting operation" state such as brake, stop, switch door, etc., as the end point of the time period of the "elevator lift operation" The time period of the "elevator lift operation" can also be called "running process"

The length of each "elevator lift operation" (that is, the running process) can be as long or as short as possible, from a few minutes to a few seconds;

Even in the same elevator, during the different “elevator lift operation” period (that is, in different operation processes), some parameters, especially the elevator item mass m1, may change. If the passenger increases, the m1 naturally becomes larger. If the passengers decrease, the m1 naturally becomes smaller.

9. The energy flow of the elevator to the working condition can also be called the operating condition of the elevator;

From the direction of elevator operation, it can be simply divided into elevator ascending, elevator descending, etc.;

From the operating conditions of the motor, it can be divided into electric state, motor braking state, etc.;

Comprehensive elevator running direction and motor operating conditions, the elevator's energy flow to the working conditions are divided into electric up, motor brake up, electric down, motor brake down and other states;

Because the elevator is usually in the state of mechanical brake when the machine is stopped, because the main purpose of the invention is to solve the problems of parameter measurement, safety monitoring, operation control and the like in the operation of the elevator, the energy flow of the elevator according to the present invention eliminates the shutdown state to the working condition.

9.1. The energy flow of the elevator to the working condition is a very important state parameter. Because the elevator structure is special (there is the existence of counterweight), even in the process of the elevator cargo moving up, the motor may be in a braking state; even if the elevator is loaded Downstream, the motor may be in an electric state;

For ease of description and to understand the present invention by those skilled in the art, the present invention stipulates the following parameter setting methods of 9.2 and 9.3:

9.2. In the later embodiment of the present invention, regardless of whether the elevator running direction is the elevator ascending and the elevator is descending, when the motor is in the electric state, the motor speed n1 and the elevator speed Vq are all agreed to be positive values; each electric power parameter ( The electric power, the electromagnetic torque Te, the torque current component iq, and the motor current Io) are all positive values; the mechanical driving force calculated according to the electrical energy is also a positive value, indicating that the motor is in a state of converting electrical energy into mechanical energy at this time;

9.3. In the later embodiment of the present invention, regardless of whether the elevator running direction is the elevator ascending and the elevator is descending, when the motor is in the motor braking state, the motor speed n1 and the elevator speed Vq are still agreed to be positive values: each electric power The parameters (electrical power, electromagnetic torque Te, torque current component iq) are negative values; the mechanical driving force calculated according to the electrical energy is also a negative value, indicating that the motor is in a state of converting mechanical energy into electrical energy at this time;

9.4. The method for identifying the energy flow direction of the elevator provided by the present invention is as follows:

9.4.1. The identification method of the elevator running direction is as follows: the signal of the central controller can be read, or the control command or status information of the motor driver (such as the forward rotation, reverse rotation of the inverter), or (such as by rotating the encoder) ) Measuring the direction of the motor's speed, you can easily obtain the elevator running direction;

9.4.2. The identification method of motor operating conditions is as follows:

Method for identifying the operating conditions of the motor for reference 1:

First, the electromagnetic torque Te of the motor and the motor speed n1 are obtained, and then the following identification is performed:

When Te and n1 are in the same direction, the current motor operating condition can be identified as: an electric state;

When Te and n1 are opposite in direction, the current motor operating condition can be identified as: motor braking state;

According to the foregoing convention, the operating condition of the motor can be naturally recognized according to the positive and negative of Te.

For the reference of the AC motor operating conditions identification method 2:

When Udc is less than the peak value of U2i, the current motor operating conditions tend to be motorized;

When Udc is greater than the peak value of U2i, the current motor operating condition tends to the motor braking state;

Motor operating condition identification method for AC asynchronous motor for reference 3:

When n1 < n0, the current motor operating conditions tend to be electric;

When n1>n0, the current motor operating condition tends to the motor braking state;

For the reference of the motor operating conditions identification method 4: Some models of motor drives, such as four-quadrant inverters, can also directly identify and judge the motor operating conditions by reading its internal status word;

For the reference of the motor operating conditions identification method 5: When the positive and negative of the source dynamic parameters of the non-electrical power parameter type can be measured (such as using a torque sensor to measure the dynamic parameters of the mechanical rotating parts), then according to the source dynamic parameters The positive and negative can identify the operating condition of the motor; when the value of the source dynamic parameter is positive, it can be judged that the motor operating condition is the electric state, and when the value of the source dynamic parameter is negative, the motor operating condition can be judged as the motor braking. status;

Critical switching area identification method for reference 1:

In the motor operating conditions, whether in the electric state or the motor braking state, a special stage is included: critical cutting Change zone; when the motor is in the critical switching zone of the motored state, it means that it is easy to enter the motor braking state; when the motor is in the critical switching zone of the motor braking state, it means that it is easy to enter the motoring state; compare some pre-selected parameters If the preset range is exceeded, it can be judged whether the operating condition of the elevator is in the critical switching area; the pre-selected parameter is preferably the source dynamic parameter.

When the motor operating condition is in the critical switching zone, it may affect the accuracy of the calculation, and the calculation or monitoring of the parameter may be suspended; a critical state identification threshold Te_gate may be set, and when |Te|<Te_gate, the current motor operation may be judged. The working condition is in the critical switching area;

9.4.3. Combine the contents of the above 9.4.1 and 9.4.2 documents to identify the energy flow of the elevator to the working condition;

9.4.4. Method for identifying the energy flow direction of other elevators 6:

The energy flow of the elevator to the working condition is related to the running direction of the elevator, as well as the change of the mass of the carried item m1, the mass of the elevator car m0, the value of the counterweight mass m3, the frictional resistance, and even the speed parameter;

When the elevator is going up, when m1+m0>m3, the elevator tends to be in an electric uplink state or an electric uplink state;

When the elevator goes up, when m1+m0<m3, the elevator tends to brake the motor up state or brake the motor up state;

When the elevator goes down, when m1+m0>m3, the elevator tends to the motor brake down state or the motor brake down state;

When the elevator goes down, when m1+m0<m3, the elevator tends to be in the electric down state or in the electric down state;

The above identification method 6 is particularly suitable when the traction machine of the elevator is a toothless traction machine, especially when the traction machine of the elevator is a permanent magnet synchronous toothless traction machine.

In today's market, elevators using turbine traction machines are nearly eliminated due to their low efficiency; such elevators, when the elevator goes up and (m1+m0<m3), when the elevator goes down and (m1+m0>m3), The motor does not necessarily tend to be in the motor braking state or in the motor braking state. At this time, the motor may even be in a weak motor state; the weak motor state means that the output torque of the motor is less than a preset value; the preset value refers to It is specially used to evaluate the weak electric state; the motor only needs to drive the elevator at a relatively small power; in this case, the efficiency coefficient Km of the mechanical transmission system of the elevator and the value of the comprehensive efficiency coefficient can be determined by a limited number of experiments and manual trials. According to the law or type test, the specific calculation method of the efficiency coefficient Km of the mechanical transmission system, the comprehensive efficiency coefficient and its related coefficients in the calculation of the energy balance of the elevator operation can also be obtained by finite experiments, manual trials, or type tests. know.

For elevators using turbine traction machines, the contents of the above identification method 6 can be used before the energy balance calculation of the elevator operation. Firstly, according to the running direction of the elevator and the relationship between (m1+m0) and m3, the situation is divided into four cases. Calculate the appropriate elevator operating energy balance calculation formula for each. Obviously, if the estimated object in the elevator energy balance calculation is the carrying item mass m1, other methods can be used to know the value of m1 (for example, by weighing the weighing method, channel inlet counting method, or video analysis method). The number of elevators knows the value of m1), and the above four cases are identified according to the running direction of the elevator and the relationship between (m1+m0) and m3, and the corresponding elevator operation energy balance calculation is performed.

10. The network system of the present invention includes, but is not limited to, various wired or wireless mobile 3G, 4G networks, the Internet, the Internet of Things, etc.; the network system may include a corresponding human-computer interaction interface, a storage system, and data processing. System, etc.; personnel or institutions related to elevator operation (such as operators, safety supervisors) can monitor elevator operation status in real time or afterwards through the network system.

Special statement 1: The method for obtaining the value of any elevator operating parameter and the energy of the elevator in all the embodiments provided in the later description of the present invention The method for identifying the flow rate to the working condition can be performed by the foregoing method, and can of course be referred to other conventionally known techniques; any setting conditions, operating conditions, thresholds, time, period, and data described in the present invention The assignment, etc., can be adjusted by the system, the operating environment, or the user according to the needs, not a single, fixed value. For example, when the main power grid is used for power supply and the backup power supply is used, the safety limit threshold of the electric power needs to be adjusted and switched.

The second part of the content: the specific invention content and specific implementation of the present invention are as follows:

The method corresponding to the technical problems of the present invention respectively corresponds to the system, that is, the essential principles of the technical solutions of the method items and the system items are the same, and the technical solutions can be applied to each other.

The preferred solution 4 of setting scheme 2: the safety-critical parameter closely related to safety in the transmission system is preferably the efficiency coefficient and/or the rolling resistance coefficient; the efficiency coefficient has a more important safety significance than the integrated transmission ratio.

Set the parameters (or their number) of the measured parameters in the input parameters, which are set based on the measured values; other parameters can be It is set by the preset value; the more the measured parameters, the higher the accuracy will be, the better the monitoring performance is; the less the measured parameters are, the lower the cost is; the user and the manufacturer can customize according to their different situations.

The effect of the aforementioned acquisition method:

In the A scheme, the measurement object is a parameter closely related to safety in the power or transmission system or a parameter including the parameter, and the value is obtained based on the energy balance calculation formula of the elevator operation, and has safety monitoring, monitoring, and data processing for the elevator. Important; if the measurement object is an efficiency coefficient or a parameter containing an efficiency coefficient, the calculation result can be used to reflect the wear and/or safety condition of the power transmission component to be monitored of the elevator; if the measurement object is an integrated transmission ratio or includes an integrated transmission The calculation result can be used to reflect the condition of the integrated transmission ratio. The abnormality of the integrated transmission ratio usually indicates a serious failure of the mechanical transmission system of the elevator;

In the B scheme: because the elevator operation energy balance calculation is a special technical solution based on the principle of energy conservation and/or the combination of Newton's law and elevator operating characteristics;

Even if the measurement object non-efficiency coefficient or the parameter including the efficiency coefficient, if the value of the efficiency coefficient included in the input parameter is a preset value (the value is preferably a calibration value), the calculation result of the elevator operation energy balance of the measurement object is available. In the case of reflecting the efficiency factor (ie the wear and/or safety of the power transmission components to be monitored);

Even if the measured object is not a comprehensive gear ratio or contains a comprehensive gear ratio parameter, if the integrated gear ratio included in the input parameters If the value is a preset value (the value is preferably a calibration value), the calculation result of the elevator operation energy balance of the measurement object may be used to reflect the condition of the integrated transmission ratio;

After in-depth research and analysis:

If the measured object is not an efficiency coefficient or is not a parameter including an efficiency coefficient, and the efficiency parameter included in the input parameter or the current actual value included in the input parameter is used as the value of the input parameter, the elevator operates The calculation of the energy balance calculation loses the ability to monitor the efficiency factor (ie the wear and/or safety of the power transmission components to be monitored);

If the measured object is not the integrated gear ratio or the parameter including the integrated gear ratio, and the input gear does not include the integrated gear ratio or the integrated gear ratio included in the input parameter to obtain the current actual value as the value of the input parameter, the elevator is performed. Running the energy balance calculation, the calculation result loses the monitoring ability for the integrated transmission ratio;

In summary, the calculation of the value of the object based on the energy balance of the elevator operation requires not only an in-depth understanding of the algorithm principle of the energy balance calculation of the elevator operation, but also an in-depth study of the characteristics of the input parameters, and selection of an appropriate elevator energy balance calculation formula and setting.

For the calculation of the elevator operating parameters other than the inherent parameters of the system, the reference value and the joint operation value of the type parameter (such as speed) may fluctuate greatly, at this time, if only by its reference value or joint operation alone Value, it is impossible to judge whether the elevator is faulty or analyze the cause of the fault, so it is necessary to simultaneously output and/or save the reference value and the joint operation value; output and/or save and output the difference between the joint operation value and the reference value And/or the joint operation value of the saved measurement object has the same meaning as the reference value.

The energy balance calculation, if the measured object is the elevator mass, the calculated value according to the parameter including at least the system operating parameter and/or the source dynamic parameter is the joint operation value, and when the measured object is the source dynamic parameter, according to at least the elevator The calculated value of the parameters including the quality and/or system operating parameters is the combined operation. Value, when the object is a calculation system operating parameters, the calculated value is the calculated value of the combined parameter includes at least an elevator according to quality and / or power source, including parameters.

In the present invention, the parameter participating in the energy balance calculation of the elevator operation includes a parameter having a subordinate meaning: the elevator operation energy balance calculation has an input parameter and an output parameter (ie, a joint operation value of the measurement object), and the input parameter and the output parameter. Together constitute the parameters involved in the energy balance calculation of the elevator operation. Therefore, including a certain parameter in the parameter participating in the energy balance calculation of the elevator operation means that the certain parameter can be either an input parameter or an output parameter.

In the present invention, the "elevator running energy balance calculation" is the calculation of the balance of the energy for controlling the operation of the elevator; the energy balance is also the energy balance; further, the energy balance preferably refers to the balance of energy per unit time, that is, the power. Further, the balance of energy preferably refers to the balance of forces; therefore, the "elevator running energy balance calculation" is preferably "the calculation of the balance of the running force of the elevator"; the "elevator running energy balance calculation" according to the present invention, That is, the elevator motion balance calculation, including the constant speed running state and the variable speed running state, refers to the balance of the power and the related force, and the elevator running energy balance is calculated as a formula according to the description of the power of the elevator and the associated force balance or its deformation.

The point O can be either the Q point shown in Fig. 1 or the point equivalent to the Q point, or the center of mass of the elevator car; V is the running direction of the elevator car; h1 and h2 represent the elevator car ( Or its equivalent Q point or centroid) the running direction is vertical; G2 is the gravity corresponding to the total mass m2 of the elevator car, G2=m2*g; G3 is the gravity corresponding to the weight m3, G3=m3*g F is the power of the elevator; the frictional force f0 between the object and the car in the guide rail and/or the elevator shaft is opposite to the running direction V; the actual direction of the power F is determined by the relationship between G2 and G3 (that is, the relationship between m2 and m3) ) and the direction of operation V is determined;

When V is vertically upward: as shown in FIG. 3, F+G3=G2; when (m2>m3), F is a positive value; that is, the actual force direction of F is the same direction as V (ie, G3);

As shown in FIG. 3 and FIG. 4, the frictional force f0 between the object and the car in the guide rail and/or the elevator shaft is always opposite to the running direction V of the elevator car, that is, the operation of the elevator car is hindered; similarly, the wind resistance fw Constantly opposite to the running direction V of the elevator car;

The operation in the present invention preferably refers to the uniform operation of the elevator car, especially the non-zero uniform speed operation of the elevator car; because the elevator car runs at a constant speed for a longer period of time than the variable speed operation of the elevator car; When the elevator is running at variable speed, the monitoring and monitoring effects are easily reduced due to the fluctuation of the speed; and when the elevator is in the shifting operation, the rate of change of the speed (that is, the acceleration) is not easy to measure, the cost is increased, and the measurement accuracy is not well controlled.

From another description, in the present invention, the elevator operation energy balance calculation is essentially a calculation based on a mechanical formula describing the influence of the power of the elevator and the related force on the elevator operation or a mechanical formula of the deformation thereof; or: elevator operation The energy balance calculation is essentially a calculation based on the dynamic equation describing the vertical direction of the elevator car; further, the calculation based on the dynamic equation describing the vertical operation of the elevator car is: according to the power including the elevator and the associated force The calculation is based on the dynamic equation describing the vertical operation of the elevator car; the dynamic equation can refer to both the basic dynamic equation and the deformation formula of the basic dynamic equation;

In the present invention, the joint operation value, that is, the joint operation data (that is, the joint operation data of the measurement object), may also be referred to as the first data or the estimated data or the estimated data or the first value or the estimated value or the estimated value; the joint operation value Refers to a data type or data acquisition path, indicating that the data is calculated based on different types of elevator operating parameters. The different types of classification are based on the elevator operating parameters into elevator quality, source dynamic parameters, system operation. Parameter three parameter types; joint operational data such as elevator mass is calculated based on data including at least source dynamic parameters and/or system operating parameters, for example, joint operational data of source dynamic parameters is based on at least elevator quality and/or Data calculated from system operating parameters, such as joint operational data of system operating parameters, calculated based on data including at least elevator mass and/or source dynamic parameters, etc.; the combined operational data of the present invention, especially Refers to the calculation of elevator operating energy balance based on different types of elevator operating parameters. Of course, other simple calculations performed (e.g., look-up table) the resulting data are also data for joint operation of the elevator based on different types of operating parameters;

From another perspective, the elevator operating energy balance calculation is to calculate another parameter based on data including at least two of the elevator mass, the source power parameter, and the system operating parameter. In the acquisition method, when the measurement object is the elevator quality, the input The input parameter includes at least a source dynamic parameter and/or a system operation parameter; when the measurement object is a source dynamic parameter, the input parameter includes at least an elevator quality and/or a system operation parameter; when the measurement object is a system operation parameter, the input parameter includes at least an elevator. Quality and / or source dynamic parameters.

The "elevator running energy balance calculation" of the present invention includes a constant speed running state and a variable speed running state. From another angle analysis, it may also refer to calculating any two parameters according to elevator mass, source dynamic parameters, and system operating parameters. A parameter; the "elevator running energy balance calculation" of the present invention generally takes the energy balance of the elevator operation as a calculation rule, and it can be understood that in the following embodiments and formulas in the present invention, the formula related to the power balance And the related formula of the force balance is also the calculation of the energy balance as a rule; because the power can also be understood as the energy per unit time, the power balance is also the energy balance per unit time, respectively. Multiplying by the equal time is the formula of the energy balance; the force can also be understood as the energy of the moving distance per unit time unit, and the force balance is the energy balance of the moving distance per unit time unit. The correlation formula of the force balance is multiplied by the corresponding time and corresponding The moving distance is also the formula of energy balance. Therefore, the elevator running energy balance calculation of the present invention includes, in addition to the combination of the elevator running characteristic and the energy conservation law, and Newton's law (Newton's first motion law, Newton's second motion law, and Newton's third motion law). Or a combination of multiple, that is, the energy balance calculation of the elevator operation is essentially a combination of the law of conservation of energy, the operating characteristics of the elevator, and Newton's law. The so-called combination refers to the calculation of a, the law of conservation of energy and the operating characteristics of the elevator. To adopt the two parameters of elevator quality, source dynamic parameters and system operating parameters to calculate another parameter, or b, in accordance with the premise of energy conservation, adopt the elevator mass and source dynamic parameters through Newton's law and elevator running characteristics. Two parameters in the system operating parameters to calculate another parameter, or c, through the law of conservation of energy, Newton's law and elevator operating characteristics to use elevator parameters, source dynamic parameters, system operating parameters to calculate another parameter.

Therefore, the essence of the energy balance calculation of the elevator operation can also be regarded as the combination of the energy conservation principle and/or Newton's law (especially the second law) and the elevator operating characteristic factors; the energy conservation principle refers to the energy output of the elevator power system (or The power is equal to the amount of energy (or power) consumed outside the power system of the elevator, and/or the energy (or power) absorbed by the power system of the elevator is equal to the energy (or power) fed back from the power system of the elevator. The elevator running characteristic means that the elevator car runs vertically along the guide rail and/or the elevator shaft under the control of the power system; since the elevator is usually operated under non-vacuum, friction with the air generates wind resistance (ie, air resistance) fw, when When running near zero speed or when the speed is lower than the preset value, fw=0; naturally there is shift resistance (m2*a, m3*a) when the vertical speed of the elevator changes, m2*a=0 and m3*a= at constant speed. 0; this is the main feature of elevator operation; the calculation of elevator operation energy balance in this paper can also be expressed as the calculation of the vertical dynamic balance of the elevator, that is, the calculation of the power of the elevator and the related force balance, therefore The elevator operating energy balance is calculated as a calculation based on a formula describing the dynamics of the elevator and the associated force balance or a variant thereof; the associated force includes the gravity and/or the counterweight mass corresponding to the total mass of the elevator car Gravity. It should be understood that the balance between the above power and the related force means that the power and the related force are in accordance with Newton's second law, where the conformity includes full conformity and approximate conformity, and the corresponding physical field is completely equal in the actual situation. And the approximation of the two is equal. When the power and the related force are completely equal, the above formula is transformed into Newton's law, that is, when the elevator runs at a constant speed, the power is equal to the relevant force (the shifting resistance is zero), when the elevator is running at a non-uniform speed, the elevator Joint force (power reduction minus all related to shift resistance) Force) equals elevator mass * acceleration (speed resistance). Approximate equality means that, in the case of complete equality, the person in the field ignores some of the smaller forces depending on the magnitude of each relevant force, such as in the case of complete equality, the associated force includes the traction sheave and the rolling friction experienced by the guide wheel. When the traction friction force of the traction sheave and the guide wheel is small, the friction force can be rolled, and the power and the related force are approximately equal. Therefore, the associated forces may also include other related forces, such as shifting resistance, traction sheave and rolling friction experienced by the steering wheel, wind resistance of the car and counterweight, objects in the car and rails, and/or in the elevator shaft. Friction and L0*β, etc., which are specifically included, need to be distinguished by the personnel in the field according to the magnitude of the relevant force in the actual operation of the elevator.

The operation of the elevator, as shown in the embodiment 11 and the embodiment 12 (that is, the two-speed differential elevator operation energy balance calculation formula), the elevator operation based on the difference of the parameters acquired at two different time points The energy balance calculation formula is possible to eliminate the influence of rolling resistance and the frictional resistance of the car and the rail and/or the object in the elevator shaft, and the core principle of the differential elevator running energy balance calculation formula is still based on the typical elevator operating energy balance. Formula (for example, formula for accelerating the ascending ((m1+m0)-m3)*g+(m1+m0)*aj+m3*ad+f0+fr+fw=(Kem1*Te)*im/R1), and The operation of the differential elevator energy balance calculation formula is limited by many preconditions: rolling friction resistance fr at two different time points, friction between the rail and the car in the elevator shaft and the car f0, wind resistance fw, elevator When the total mass m2 of the car and the weight mass m3 are close, and the accelerations a2 and a1 obtained at two different time points (assuming a2=aj2=-ad2, a1=aj1=-ad1) are not equal, it is possible to get the difference. Formula for calculation of energy balance of value elevator operation (m2=(fq2-fq1)/(a2-a1)+m3) When f0, fr, fw, m2 and m3 at two different time points are close, it is possible to obtain the equation for calculating the energy balance of the differential elevator operation m2=Kem1*im*(Te2-Te1)/((a2-a1) *R1)+m3 (wherein the electromagnetic torque acquired by Te2 and Te1 at two different time points respectively); in the present invention, the calculation formula of the elevator running energy balance based on the difference of the parameters acquired at two different time points, A special variant of the energy balance calculation formula based on typical elevator operation.

In the present invention, the elevator operation energy balance calculation can also be understood as a feature of calculating another type of elevator operation parameter based on data including at least different types of elevator operation parameters; the different types of classification are based on the elevator operation parameters. Divided into three types of parameters: elevator quality, source dynamic parameters, and system operating parameters;

In combination with the following embodiments 1 to 6 and the like, it is obvious that in the present invention, another parameter is calculated according to any two parameters of the elevator mass, the source dynamic parameter, and the system operating parameter, and the parameters participating in the calculation may further include Other data, ie, elevator operating energy balance calculations, generally refers to calculating another parameter based on data including at least two of the elevator mass, the source dynamics parameter, and the system operating parameters. When the object to be calculated is the item mass m1 in the formulas 1-1 and 1-4 in the embodiment 1, the parameters participating in the calculation also include m0 in the elevator mass; in the formula 4-13 in the embodiment 4, the measurement object is the system operation. When the frictional force fr of the rotating member in the parameter, the parameters involved in the calculation also include the frictional force f0 between the object and the car in the guide rail and/or the elevator shaft; the object measured in the formula 5-1 in the embodiment 5 is the system operating parameter. In the elevator speed, the parameters involved in the calculation also include g in the system operating parameters, which are not listed here. For specific reference, the following embodiments may be referred to;

When the measured object is the elevator quality, the joint operation value of the elevator quality is calculated according to the source power parameter and/or the system operation parameter, and of course, the parameters required to participate in the calculation may further include other data such as other in the elevator quality. Parameter; also That is, when the measurement object is the elevator quality, the joint operation value may be calculated according to data including at least source power parameters and/or system operation parameters;

When the measured object is a source dynamic parameter, the joint operation value of the source dynamic parameter is calculated according to the elevator mass (usually the total mass of the elevator car and/or the counterweight mass) and/or the system operating parameter, and of course participates in the calculation. The required parameters may further include other data; that is, when the measured object is a source dynamic parameter, the joint operational value may be based on at least the elevator mass (typically the total mass of the elevator car and/or the counterweight mass) and / Or data calculated from system operating parameters;

When the measured object is a system operating parameter, the joint operation value of the system operating parameter is calculated according to the elevator mass (usually the total mass of the elevator car and/or the counterweight mass) and/or the source dynamic parameter, and of course participates in the calculation. The required parameters may further include other data, such as system operating parameters other than the measured object; that is, when the measured object is a system operating parameter, the combined operational value may be based on at least the elevator quality (usually an elevator) Calculated from data such as total car mass and/or weight quality) and/or source dynamic parameters;

Of course, the table obtained by the deformation calculation formula of the elevator running energy balance is obtained. If the total mass m2 of the elevator car and/or the counterweight m3 is fixed, the power and system operating parameters are obtained by the energy balance calculation formula of the elevator running one by one. Especially for the corresponding relationship of the mechanical operating parameters), or when the power and the counterweight m3 are fixed values, according to the elevator running energy balance calculation formula look-up table, the corresponding relationship between the total mass of the elevator car and the mechanical operating parameters is obtained. Or when the system operating parameters and the counterweight m3 are fixed values, according to the elevator running energy balance calculation formula, the correspondence between the total mass of the elevator car and the power is obtained, and the calculation formula based on the energy balance of the elevator is simplified or It is also within the scope of the present invention to ignore certain parameters for calculation and also for a variant of the elevator operating energy balance calculation formula.

The joint operation value is calculated based on the calculation formula of the elevator running energy balance, and all the values calculated based on the elevator running energy balance calculation formula are the joint operation values.

The most typical elevator running energy balance calculation formula such as: (m1 + m0) * g - m3 * g = (Kem1 * Te) * im / R1, elevator running energy balance calculation formula has infinite deformation, Deductive

The elevator quality includes the total mass of the elevator car and/or the weight of the counterweight. The type setting of the parameters of the elevator quality is determined according to the signal value position of the source power parameter. When the signal value of the source power parameter is the wire rope on the car side When the elevator quality is selected, the total mass of the elevator car (which includes the quality of the empty car and the mass of the carried goods); when the signal of the source dynamic parameter is taken as the traction sheave and its front end (traction wheel, or traction) When the transmission component between the wheel and the motor, or the motor, or the motor drive, or the power supply device, etc., the elevator mass can select the total mass and the counterweight mass of the elevator car; when the signal value of the source power parameter is the counterweight side When the wire rope is used, the elevator quality can be selected as the counterweight quality;

The invention relates to "the elevator running energy balance calculation is associated with the elevator running direction", that is, "the algorithm for adjusting the elevator running energy balance calculation according to the elevator running direction", which refers to a technical solution, the nature of the calculation applicable range It is not necessary to start the calculation in a certain running direction;

For example, when the elevator is running at zero speed, the safety limit threshold of the electric power parameter of the elevator and the current value of the carrying quality are calculated. The value of the upward speed and/or the upward acceleration, which can usually be used as the upper limit threshold for the elevator as it goes up; for example, when the elevator is running at zero speed, the preset command value and the carrying quality of the down speed and/or the down acceleration are used. The value of the source dynamic parameter calculated by the current value, which is usually used to determine whether the source dynamic parameters (such as the comprehensive tension of the wire rope) will exceed the limit when the elevator is descending;

The "elevator running energy balance calculation is associated with the elevator running direction" according to the present invention includes any one or two of the following running direction association 1 and the running direction association 2, and the association 1 and/or the running direction according to the running direction. Correlation 2 deformation, derived association relationship; set the calculation formula according to the association principle when the elevator goes up and the elevator goes down;

Running direction correlation 1: When the elevator is going up: the gravity component (m2*g) generated by the carrying mass m2 and the gravitational acceleration g is the energy absorption factor, and the gravity component (m3*g) generated by the counterweight mass m3 and the gravitational acceleration g is energy. Release factor; when the elevator descends: the gravity component generated by the mass m2 and the gravitational acceleration g is an energy release factor, and the gravity component generated by the weight m3 and the gravitational acceleration g is an energy absorption factor; according to the energy absorption and/or release law In the different running directions of the elevator, different calculation formulas are set for the carrying mass m2 and the counterweight mass m3; for example, the formula 3-1, the formula 4-1, the formula 4-2, the formula 3-2, and the formula 4-3 are described later. , Equation 4-4;

Running direction correlation 2: When the elevator goes up and the elevator goes down, the calculation formula of the gravity component generated by the elevator mass and the gravity acceleration g does not change, but the positive and negative polarities of the source dynamic parameters are switched when the elevator goes up and the elevator goes down;

For example, referring to Equation 3-1, the calculation formula 3-100 is used when the elevator is ascending:

(m1+m0)*g-m3*g=T1/R1, (Formula 3-100);

When the elevator descends, the calculation formula 3-101 is adopted:

(m1+m0)*g-m3*g=-T1/R1, (Formula 3-101);

Or when the elevator goes down, the form of the calculation formula 3-100 is not changed, but the (T1/R1) is substantially switched to a negative value; for example, when the elevator is ascending, the T1 is forced to be positive, and when the elevator is descending, the T1 is forced to be negative. value.

In the above-mentioned running direction correlation 2, it is a necessary step to switch the positive and negative polarities of the source power parameters when the elevator is going up and the elevator is going down.

It can be seen that when the elevator is running at zero speed, it is necessary to calculate the energy balance calculation of the elevator and the running direction of the elevator. Otherwise, the result of the calculation will be wrong. In practical applications, the running direction association 1 is clearer and more concise than the running direction correlation 2; the running direction correlation 1 is more in line with the energy flow direction rule in the elevator operation; because the positive and negative of the source dynamic parameters reflect the motor operating conditions, compared with the use source The positive and negative of the dynamic parameters reflect the more scientific direction of the elevator; the direction of operation 3 is easy to make the calculation expression complicated and chaotic.

In the present invention, the method for calculating the efficiency coefficient according to the operating condition of the motor is simply referred to as "adjusting the efficiency coefficient according to the operating conditions of the motor", which includes the following motor operating conditions: 1. Motor operating conditions Any one or more of the associations 2, and the associated relationship between the motor condition 1 and/or the motor operating condition 2 deformation and derivation;

Motor operating condition correlation 1: When the motor is in the electric state, the motor absorbs electric energy and converts it into mechanical energy. According to the principle of energy conservation, the electric power parameter is multiplied by an efficiency coefficient less than 1 (such as Kem1);

Motor operating condition correlation 2: When the motor is in the motor braking state, the motor absorbs mechanical energy into electrical energy. According to the principle of energy conservation, the electrical power parameter is divided by an efficiency coefficient less than 1 (such as Kem2);

The present invention "types the electrical power according to the operating conditions of the motor", which is simply referred to as "the setting of the electrical power according to the operating conditions of the motor", which includes the following motor operating conditions. Any one or more of the working condition associations 4, and the associated relationship between the motor operating condition association 3 and/or the motor operating condition correlation 4;

Motor operating condition correlation 3: When the motor is in the electric state, the motor absorbs electric energy and converts it into mechanical energy. At this time, the electric power is selected as the electric system power in the electric state (such as the electric state power of the power source, the motor driver, or the motor). );

Motor operating condition correlation 4: When the motor is in the motor braking state, the motor absorbs mechanical energy into electrical energy. At this time, the electrical power is selected as the power of the electrical system when the motor is in braking state (such as power generation feedback braking power P4, or energy consumption). Braking power P5, etc.);

The principle of the speed change of the elevator is as follows: When the acceleration is running, the speed component of the elevator mass and acceleration is the energy absorption factor; when the speed is running, the speed component of the elevator mass and acceleration is the energy release factor; when the speed is running, the acceleration At zero, the shifting force component produced by the elevator mass and acceleration is also zero.

The present invention "calculates the elevator operation energy balance according to the elevator speed change condition", comprising performing the following speed change association 1 and/or speed change association 2 processing according to the speed change condition correlation principle;

Rapid change correlation 1. The parameters participating in the calculation of the energy balance calculation of the elevator include acceleration;

Speed change correlation 2. Identify the speed change condition of the elevator, and perform the elevator operation energy balance calculation or processing separately during the constant speed operation and the variable speed operation.

The identification of the speed change condition can be identified by the acceleration aj value: when the ag is 0 or less than a preset threshold when the elevator is running, the current speed change condition can be identified as non-zero constant speed operation; when aj is not 0 Or greater than a preset threshold, the current speed change condition can be identified as a variable speed operation; wherein the acceleration aj value can adopt various acquisition manners as described above (such as by an acceleration sensor, or a speed Vq, or a speed n1, etc.) It can also be obtained through the information of the motor driver (such as the existing inverter has a uniform flow overcurrent, acceleration overcurrent and other information, through which the speed change can be extracted); and an easier way to distinguish the speed according to the running time. The change condition, such as the acceleration running time of the motor driver (such as the inverter) is 2 seconds, the setting is the shift running time period within 3 seconds after the start, and the non-zero constant speed running time period after 3 seconds;

Preferably, the parameter participating in the calculation of the energy balance calculation of the elevator includes acceleration, which is measured according to the acceleration sensor. Acceleration obtained according to the calculation method such as detection speed or speed change: aj=(Vq_1-Vq_0)/t; this method firstly detects the speed Vq. When the elevator runs at low speed, the measurement error is large because Vq is much smaller than the full scale. It is close to zero speed operation, the error is larger, it is basically impossible to use; and according to the acceleration measured by the acceleration sensor, it has the advantages of fast response and high precision, and can be well applied to low speed operation, especially zero speed operation, remarkable Improve the measurement accuracy of elevator operating parameters;

More importantly: because the elevator is either up or down, it must start from zero speed and gradually accelerate to a constant speed. First, judge whether it is overloaded at zero speed or whether it should give up running/warning signal; then the target acceleration can be performed. / Scientific planning of target acceleration time and target speed; once the current car sensor weighing scheme in the car is abandoned due to cost problems, the accelerometer measurement acceleration is further combined with the elevator running energy balance calculation. It is of great significance for elevator overload/safe operation of elevators and efficiency improvement.

There are many calculation methods for the joint operation value of the measurement object, one is the table lookup calculation; if the elevator quality, the source dynamic parameter, and the system operation parameter are preset, the table can be checked when any two parameters are input.

The reference data of the present invention, that is, the reference data of the measurement object, that is, the data for energy transfer condition recognition, that is, the energy transfer condition identification data, is used for performing the energy transfer abnormality judgment in conjunction with the joint operation value. /Compared data or value, because a single data cannot constitute a complete comparison/judgment operation; the joint operation value is a result calculated based on the elevator running energy balance calculation formula. The reference data described herein includes or is the energy transfer condition identification data; the energy transfer condition identification data includes or is any one or two of the energy transfer condition identification difference value and the energy delivery amount status identification value; For ease of description, the energy transfer condition identification value, that is, the first reference value, may also be referred to as the second permission range, that is, the second range; the energy transfer amount condition identification difference described herein may also be referred to as the first A permitted range is also the first range, which is the license deviation value. The reference data includes any one or more of a reference value, a license deviation value, and a first reference value; the reference value used in the present invention is also a reference value for energy transfer condition identification, that is, an energy transfer condition identification reference value. The permission deviation value in the present invention is also the deviation value for the energy transmission condition identification, that is, the energy transmission condition identification deviation value; obviously, the reference data of the measurement object or the data included in the reference data in the present invention are required. It is configured to perform data for abnormality determination of the energy transfer amount for the joint operation value calculated with the calculation object calculated based on the energy balance calculation formula of the elevator; the reference data is reasonable data capable of realizing the use; and the operation according to the measurement object and the elevator The energy balance calculation formula and the setting method of the input parameter of the elevator energy balance calculation formula are different, and the reference data of the corresponding measurement object is set.

Technical solution in the monitoring method (#1) and/or the monitoring method (#1-2) and/or the monitoring method (#1-3) and/or the monitoring method (#1-4) of the present invention, the reference value (and / or actual value), it must consider practical technical means or implementation, its value is naturally constrained to the specific value time and / or value mode; according to the specific setting scheme of the reference data described later ( For example, the source of the data or the selection of the value path, the setting method, the time of the value, etc., and the related embodiments (Examples 1-10), it is obvious that the measurement object is different and/or the actual value is set according to the method. The reference value (and/or the actual value) in the monitoring method of the present invention has a plurality of different time ranges, a plurality of different value ranges, and can be implemented by a plurality of different technical methods or schemes. The following principle may be adopted: at least one of the reference data and the input parameter takes a preset value and determines a parameter number of the input parameter that takes a preset value; the preset value includes a calibration value or the same state as the current elevator running state. History value under;

The reference data is preferentially the actual value or the preset value; the preset value includes the calibration value or the historical record value in the same state as the current elevator running state;

For example, in the monitoring method, in addition to the parameter of the preset value in the reference data and the input parameter, the other parameters take the actual value. For example, in Equation 4, Equation 4-17 combines fr=(m0+m1+m3)*g*μ1, reference data of f0, m0, R1, im, g, μ1, m3, and kem1 are preset values, and others. All the parameters m1 and Te are actual values; in the embodiment 11, the reference data of m2, Kem1, R1, and m3 are preset values (the reference data of m2 is especially a preset actual value, that is, the energy of the elevator operation performed in advance) Balance is obtained), all other parameters Te1, Te2, a2, a1 are actual values.

For example, in the monitoring method, when only one of the reference data and the input parameter takes a preset value: the reference data is taken The preset value, the input parameter takes the actual value, and is used to monitor whether the elevator energy transmission condition is abnormal; wherein the preset value taken by the reference data is a historical record value in the same state as the current elevator running state; in the present invention, The historical record value in the same state as the current elevator running state refers to the difference between the elevator running condition and the current elevator running condition when the value of the historical record value is lower than a preset threshold;

Preferably, when the measurement object is a parameter capable of describing an attribute of a part of the elevator, the elevator energy transmission quantity condition can be specifically a condition representing the part, for example, in the joint operation formula of kem in Embodiment 9, the reference of Kem The data takes a preset value, and when all the input parameters take the actual value, it is possible to monitor whether the part (such as the transmission component) described by kem is abnormal; in Embodiment 1, the reference data of m2 takes a preset value (such as self-learning). When the input parameters are all taken to the actual value, the condition described by m2 (such as whether the car is intact or whether the item is dropped) can be monitored.

For example, the reference data takes an actual value, and one of the input parameters takes a preset value, and is used to monitor whether the parameter of the input parameter takes the preset value is abnormal; the preset value of the parameter in the input parameter is the current elevator running state. The historical value in the same state, or the calibration value when the elevator is shipped from the factory; taking Example 2 as an example for description, the reference data of m2 takes the actual value, and μ1 takes the preset value and the remaining parameters take the actual value, which can be monitored. Whether μ1 is abnormal; if the reference data of m2 takes the preset value, ki takes the preset value and the remaining parameters take the actual value, it can monitor whether ki is abnormal. It should be understood that, for an input parameter taking a preset value or an abnormality of a monitoring object, when the input parameter or the monitoring object of the preset value is a parameter when the measurement object is an attribute capable of describing a part of the elevator, the elevator can The delivery condition can be specifically representative of the condition of the component.

The reference data takes a preset value, and N-1 of the input parameters take a preset value, which is used to monitor whether the parameter of the preset value is abnormal in the measurement object and the input parameter; wherein, the preset value of the reference data is The historical record value in the same state of the current elevator running state, or the calibration value when the elevator is shipped from the factory; the preset value taken by the two parameters in the input parameter is the historical record value in the same state as the current elevator running state, or The calibration value of the elevator when it leaves the factory; continue to use the example 2 as an example. When the reference data of m2 takes the preset value, if the input parameter takes μ1 to take the preset value and the other parameters take the actual value, can it monitor whether m2 and μ1 are Abnormal; when the reference data of m2 takes the preset value, if the input parameter μ1 and ki take the preset value and the other parameters take the actual value, it can monitor whether m2, μ1 and ki are abnormal.

For example, the reference data takes an actual value, and N of the input parameters take a preset value, which is used to monitor whether the parameter of the input parameter takes the preset value is abnormal; wherein, the preset value of the N parameter in the input parameter is The historical value in the same state as the current elevator running state, or the calibration value when the elevator is shipped from the factory. For example, in Embodiment 8, when the reference data of Te takes the actual value, and m2, μ1, im, and R1 of the input parameter take the preset value and the remaining input parameters take the actual value, it is possible to monitor whether m2μ1, im, and R1 are abnormal; When Te's reference data takes the actual value, m2, μ1, im, θ, and R1 in the input parameters take the preset value and the remaining input parameters take the actual value, it is possible to monitor whether m2, μ1, im, θ, and R1 are abnormal. It should be understood that other situations regarding the relationship between the number of preset values and actual values in the reference data and the input parameters and the specific use may be performed by those skilled in the art based on the above description and specific embodiments, where I will not repeat them one by one.

E.g:

If the value of the rolling resistance coefficient μ1 included in the input parameter is the calibration value when the elevator is shipped from the factory, the reference data of the measuring object is the actual value; the method can be used to reflect the rolling resistance coefficient (that is, the traction sheave and/or the guide wheel) Anomaly caused by wheel deformation;

If the efficiency coefficient and/or the rolling resistance coefficient included in the input parameter are the calibration values when the elevator is shipped from the factory, the reference data of the measurement object is an actual value; correspondingly, the method can be used to reflect the efficiency coefficient and/or the rolling resistance. Anomalies in the coefficients (ie, caused by abnormalities in the powertrain and/or mechanical transmission system and/or deformation of the elevator traction sheave and/or the guide wheel);

E.g:

In the reference data in the monitoring method (#1) and/or the monitoring method (#1-2) and/or the monitoring method (#1-3) and/or the monitoring method (#1-4) of the present invention The reference value (and/or actual value) is a value subordinate to the measurement object type and/or the actual value (and/or reference value) setting method, and is a concept of amplitude (ie, size), which is an intermediate layer. Data; the reference value (and/or actual value) in the reference data in the monitoring method of the present invention is generally a value close to or equal to the actual value of the measured object of the elevator when the joint operation value is taken; Usually, in most cases, most of the time, the range of values of the reference value (and / or actual value) in the reference data in the monitoring method can be applied to most types of measurement objects, such as source dynamic parameters, mechanical operating parameters. As shown in Embodiments 7 and 9, when the reference value is set in accordance with the measured value in the same time range as the value of the joint operation value, the reference value (in this case, the measured value) is usually The value of the measured object with the elevator is close to or equal to the actual value when the joint operation value is taken;

As shown in Embodiment 6, when the reference value (and/or actual value) is set in accordance with (when the set condition is satisfied) When the joint operation value is set, the reference value (and/or the actual value) is also naturally a value close to or equal to the joint operation value of the "(a specific) meets the set condition"; "Specific" when the set condition is met" is the time specified by the user or the system (used to set the reference data). Usually, the elevator can be operated in the normal state by default. The reference value (that is, the joint operation value) is usually It is a value close to or equal to the actual value of the measurement object when "(a specific) meets the set condition; the setting method of such reference value is generally applicable when the measurement object is the elevator mass (m0, m1, m2) , m3) or system inherent parameters; when the measured object is the elevator mass, because the value of the elevator mass usually does not change much during the same period of time when the elevator is controlled by the power unit, the value of the reference value is usually It is still possible that the actual value of the joint operation value of the elevator (acquired for the energy transfer condition abnormal judgment) is close to or equal to the actual value of the calculation;

As shown in Embodiment 8, when the reference value is set according to the system default value, the reference value (that is, the system default value) is usually in the system default (usually the standard state) with the measurement object. The values of the actual values that are equal or close to each other are usually the calibration values; the setting of such reference values is usually applied when the measurement object is the inherent parameter of the system or the elevator mass (m0, m3) with a fixed amplitude.

The setting conditions of the reference data include two conditions of manual preset and a set parameter reaching the preset value; the artificial preset condition includes a manual input confirmation signal; and the set condition is also called the compliance setting. condition.

The energy transfer condition abnormality of the present invention may be simply referred to as energy transfer abnormality, and the energy transfer abnormality of the present invention includes any one or more of the following A1-1 and A1-3:

A1-1. The difference between the joint operation value and the reference value exceeds the permission deviation value; in any aspect of the present invention, in order to facilitate understanding by those skilled in the art, when the measurement object is an unmeasurable parameter and/or When any one of the preset parameters and/or the system inherent parameters is used, when the reference data of the measurement object is or includes the actual value (ie, the reference value), the actual value is also allowed to be replaced by the calibration value;

A1-3. The joint operation value exceeds a first reference value of the measurement object;

The typical setting scheme for the reference data is as follows:

1. When the measurement object is any one of a parameter to be measured and/or a measurable parameter and/or a source dynamic parameter and/or a mechanical operation parameter: the reference data of the measurement object includes an actual value or is actual a value, or the reference data includes an actual value and a first permitted range, or the reference data is an actual value and a first permitted range, or the reference data includes a second permitted range or a second permitted range;

The first permission range is set according to a preset value; the second permission range may be composed of the actual value and the first permission range; the second permission range=actual value+first permission range; any one of the actual value and the second permission range And the data is set according to the measured value, and the time value of the reference data (actual value and/or the second permission range) and the value of the joint operation value are within a preset time range; Or: any one or more of the actual value and the second permission range are set according to the historical record value of the measurement object, and the difference between the elevator running condition and the current elevator running condition when the historical value is taken The degree is below the preset threshold.

2. When the measurement object is any one of unmeasured parameters and/or preset parameters and/or system inherent parameters:

The reference data of the measurement object includes a second permission range or a second permission range; and the second permission range is a joint operation value setting obtained according to the preset value or the elevator operation energy balance calculation performed when the set condition is satisfied;

Or the reference data includes a calibration value or a calibration value; the calibration value is a joint operation value setting obtained according to the preset value or the elevator operation energy balance calculation when the set condition is satisfied;

Or the reference data includes a calibration value and a first permission range, or the reference data is a calibration value and a first permission range; the first permission range is set according to a preset value; and the calibration value is according to a preset value or a satisfaction setting. Setting the joint operation value obtained by calculating the energy balance of the elevator operation when the condition is determined;

The second license range may be composed of the calibration value and the first license range; the second license range=calibration value + first license range;

3. When the measurement object is any parameter in the elevator quality: the reference data of the measurement object includes an actual value or an actual value, or the reference data includes a second permission range or a second permission range, or The reference data includes an actual value and a first permitted range, or the reference data is an actual value and a first permitted range;

The actual value of the elevator mass including the quality of the carried item can be set in various ways; for example, the actual value of the mass of the carrying item m1 or the total mass m2 of the elevator car manually input by the elevator; the actual value can also be set according to the measured value. For example, a load cell is arranged on the elevator to measure the quality of the carried item; a second permission range of the elevator quality can also be manually input; the first permitted range is set according to a preset value; and the second permitted range is determined by the actual value and the first permitted range. Composition; second license range = actual value + first license range;

Preferably,

4A1. The actual value of the elevator quality and any one or more of the second permission ranges are set according to the joint operation value obtained by calculating the elevator operation energy balance when the set condition is satisfied; or

4A2. Any one or more of the actual value of the elevator quality and the second permitted range are set according to the historical record value; or

4A3. Any one or more of the actual value and the second permitted range of the elevator mass are set according to the preset value.

From the invention principle and the basic technical scheme and effect analysis, the above A1-1 situation is substantially equivalent to A1-3;

The license deviation value includes any one or more of an upper limit deviation value and a lower limit deviation value; the upper limit deviation value is an upper limit deviation value for identifying an energy transfer condition, that is, an energy transfer condition identifying an upper limit deviation value; The lower limit deviation value is a lower limit deviation value for identifying the energy transfer condition, that is, the energy transfer condition identifies the lower limit deviation value;

A1-1. The difference between the joint operation value and the reference value exceeds the permission deviation value;

The first reference value includes any one or more of the first reference value upper limit value and the first reference value lower limit value; the excess of the present invention includes greater than a certain upper limit value, less than a certain lower limit value, and the like. Any one or more of the conditions;

The case of A1-1 includes any one or two of the following A1-1-1 and A1-1-2;

A1-1-1. The difference between the joint operation value and the reference value is greater than the upper limit deviation value;

A1-1-2. The difference between the joint operation value and the reference value is less than the lower limit deviation value;

The case of A1-3 includes any one or two of the following A1-3-1, A1-3-2;

A1-3-1. The joint operation value is greater than a first reference value upper limit value;

A1-3-2. The joint operation value is less than a first reference value lower limit value;

In summary, the first reference value=the reference value (and/or the actual value)+the permission deviation value, the permission deviation value has at least one of an upper limit deviation value or a lower limit deviation value, and the first reference value corresponds to the first The reference value upper limit value and the first reference value lower limit value, the first reference value upper limit value is a reference value (and/or actual value) plus a positive value, and the first reference value lower limit value is a reference value (and/or Actual value) plus a negative value or subtract a positive value.

When the permission deviation value has an upper limit deviation value and does not have a lower limit deviation value: whether the energy transfer condition of the elevator is abnormal according to whether the joint operation value is greater than the first reference value, and when the joint operation value is greater than the first reference value, the energy transfer is performed. The situation is abnormal, otherwise no abnormality occurs;

When the permission deviation value has a lower limit deviation value and does not have an upper limit deviation value: whether the energy transfer condition of the elevator is abnormal according to whether the joint operation value is smaller than the first reference value, and when the joint operation value is smaller than the first reference value, the energy is indicated The delivery status is abnormal, otherwise no abnormality occurs;

When the permissible deviation value has both the upper limit deviation value and the lower limit deviation value: the first reference value upper limit value = the reference value (and/or the actual value) + the upper limit deviation value, the first reference value lower limit value = the reference value (and/or Actual value) + lower limit deviation value, according to whether the joint operation value is less than the first reference value lower limit value and whether the joint operation value is greater than the first reference value upper limit value to determine whether the elevator energy transfer condition is abnormal, when the joint operation value is greater than the When any one of the reference value upper limit value and the joint operation value is smaller than the first reference value lower limit value, the energy transfer condition is abnormal, otherwise no abnormality occurs.

It should be understood that the first reference value = reference value x scale factor, at this time the license deviation value = reference value (and / or actual value) × scale factor - reference value (and / or actual value). If the scale factor is 0.8-1.1, the upper limit deviation value = 0.1 × reference value (and / or actual value), and the lower limit deviation value = -0.2 × reference value (and / or actual value).

Generally speaking, the license deviation value is as small as possible to improve the sensitivity of the monitoring, but it is necessary to maintain a certain number of values to reduce the false trigger rate of the monitoring; that is, preferably, when the reference data includes or is the first permitted range With the reference value (and/or actual value), the sum of the first permitted range and the reference value (and/or the actual value) is within the safe range; when the reference data includes or is the first permitted range and the calibration value The sum of the first permitted range and the calibration value is within the safe range. Preferably, when the reference data includes or is the second permission range, the second permission range is within the safe range. Because the value of the license deviation value is small, the first reference value upper limit value according to the setting may be far lower than the safety limit threshold of the measurement object; therefore, the monitoring method (#1) provided by the present invention can break through the prior art. Limitations of safety monitoring when the elevator operating parameters do not exceed the safety limit threshold:

Core Step 3 of the present monitoring method (#1) and/or monitoring method (#1-2) and/or monitoring method (#1-3) and/or monitoring method (#1-4): Perform the following 8B1 Any one or more of the 8B2 solutions; abnormal energy transfer in the elevator operation may lead to serious safety accidents, and need to respond to the treatment in a timely manner; if not timely response / or start related safety measures.

The information about the energy transfer status of the present invention includes a determination result of determining whether the energy transfer condition of the elevator is abnormal; and the value of the energy transfer condition correlation factor of the elevator may also be included, as well as the value of the external control system requirement, and may also include The calculation The joint operation value of the object, the reference value, the license deviation value, the difference between the joint operation value and the reference value, and any one or more of the first reference values

The output of the present invention includes a human-machine interface, a network system, a connection port, an external control system, etc. for outputting data to the car and/or the monitoring center; in particular, the monitoring method/system provided by the present invention ( #1), independent of the elevator control/drive system, it is more necessary to output data to an external control/drive system to process abnormal information in time; the human-computer interaction interface includes a display, a voice system, an indicator light, etc.; The connection port can be used by an external human-machine interface, the network system to read data directly or by communication, so that relevant personnel (such as elevator passengers and/or elevator service personnel) or institutions (such as building services, remote network supervision centers) ) can directly or indirectly view the listening and monitoring data.

The preservation of the present invention includes storing the data in a storage system, a network system, an external control system, and the like in the monitoring system; so that the personnel or institutions (such as occupants and supervision centers) associated with the elevator operation can arbitrarily retrieve and monitor the data; The storage module includes a U disk, a hard disk, etc.; it can form a black box function similar to an airplane, which is convenient for post-mortem analysis.

The energy transmission abnormality processing mechanism of the present invention includes, but is not limited to, a voice prompt alarm, an audible and visual alarm, a selective execution of a protection action according to an elevator current operating condition, an activation energy transmission failure monitoring mechanism, and an alarm information output to the car. Human-computer interaction interface, man-machine interface of the hall door, network system, connection port, etc.; emergency stop, immediate reverse operation, set distance, etc.; machine system and manual can be arbitrarily combined to set various processing actions; energy transfer exception handling The mechanism can also be referred to as a security processing mechanism.

The alarm information of the present invention may include, but is not limited to, time, location, cause of the alarm, value of any one or more elevator operating parameters during the alarm, and the like;

The selective execution of the protection action according to the current operating conditions of the elevator according to the present invention refers to checking the current operating conditions of the elevator and then performing related actions; and may include but not limited to the following solutions:

Case 1: Check whether the reference data is set correctly; if the reference data is not set correctly or is not set, the related alarm information is masked and no protection action is performed;

Case 2: Check whether the value of each input parameter in the calculation of the joint operation value is within the preset time range; if the preset time range is exceeded, such as 1 millisecond, the related alarm information is masked and output is not executed. Protection action

Case 3: When the elevator is in the process of debugging and parameter testing, no protection action can be performed.

The reference data of the present invention needs to consider two aspects; one is the data property of the reference data (including the data type/path of data acquisition); the other is the value of the reference data or the set time;

The data type of the reference data of the present invention and/or the method for obtaining the data may include the measured value, the command response value, the estimated value, the learned value of the current running, the system preset value, the manual input value, and the like; wherein the system The preset value can be divided into historical record values, system default values, and the like;

The value of the elevator running parameter according to the present invention can be divided into a current value and a preset value according to time; the current value refers to the current actual value of the elevator running parameter, and may include the current measured value, the current joint operation value, and the current value. Command response value, etc.; preset values of mechanical operation parameters include system preset values, manual input values, command preset values, etc.;

The preset values of the source power parameters include system preset values, manual input values, and the like;

The current value of the carrying quality, including the current joint operation value, the current measured value (measured by the load cell), etc.;

The preset value of the carrying quality, including the system preset value, manual input value, etc.;

The command value is divided into a preset value and a command response value; the preset value is a software control command for the elevator uplink speed and the downlink speed and the acceleration in each speed change direction, and the command preset value is usually generated by software for controlling the speed of the elevator. And/or acceleration, that is, as the target value of the elevator upstream speed and/or the down speed and/or the acceleration of each speed change direction for controlling the operation of the elevator; in general, if there is no limit, the command value is divided into preset values. If the current speed is zero, when the system issues a preset value of 2m/s speed, the elevator usually needs an acceleration process to reach the target speed; the command response value refers to the value that the elevator can actually respond/execute after receiving the preset value of the command. Compared with the preset value of the command, the meaning tends to the target value, and the meaning of the command response value tends to the process value; if the acceleration running time of the elevator's frequency converter is set to 4 seconds, the inverter will issue 2m/ at zero speed. After 2 seconds of the speed command of s, the actual speed of the elevator is about 1 m/s (not 2 m/s);

The estimated value refers to the numerical value calculated according to the computer or network system, which can simulate/simulate the elevator operation;

The learning value of the current running is generally a value set in the current running flow, based on the joint operation value obtained by calculating the elevator running energy balance performed when the set condition is satisfied;

The historical record value refers to the value of the learned record that has been experienced in the elevator's past lifting operation; if the learned operation value of the learned record is the historical record original value, if the learned record's reference value is the historical record reference value, such as The actual value of the learned record is the actual value of the history;

The system default value, also known as the original value, the factory value; is the simplest data setting method, each parameter can set the system default value when the elevator leaves the factory;

The manual input value refers to the value set by the elevator controller according to the actual situation;

The reference data includes various setting manners and times according to different measurement objects:

When the measured object is the mass of the carrying item whose amplitude may vary greatly, the value is usually unchanged during the running of the elevator; the preferred method is the joint obtained by calculating the energy balance of the elevator running according to the set condition. The operational value sets the reference data; as shown in subsequent embodiment 6 and its alternative and/or extended embodiments;

When the measurement object is the inherent parameter of the system (such as rolling friction resistance coefficient, efficiency coefficient), this kind of parameter is not convenient for actual measurement in elevator operation, but the amplitude of this type of parameter is relatively stable during normal operation of the elevator; according to the default value of the system The reference data is the simplest method, and the reference data can also be set according to the joint operation value obtained by calculating the elevator operation energy balance performed when the set condition is satisfied; the set time of the reference data can be used in the elevator. Before the operation, it may be the beginning of the current operation; as shown in subsequent embodiments 7, 8 and their alternative and/or extended embodiments;

When the measurement object is any one of the source dynamic parameter and the mechanical operation parameter whose amplitude may vary greatly, the preferred method sets the reference data according to the measured value; and the time value of the reference data is combined with the reference The value of the operation value is within a preset time range (ie, synchronization); as shown in subsequent embodiment 9 and its alternative and/or extended embodiments; measured values, compared to other command values, The estimated value can more truly represent the condition of the elevator operating parameter; there is also a possibility to set the reference data according to the historical record value of the measured object;

Usually the subsequent energy transfer abnormality judgment/execution is performed after the reference data has been set, which simplifies the system; of course, it also allows direct execution of the energy transfer abnormality judgment, and checks the reference data (or the reference in the subsequent energy transfer abnormality processing mechanism). Value) Whether the setting is completed/or the setting is correct. If the reference data (or reference value) is not set correctly, the current monitoring warning signal/and action is blocked.

In the normal case, the joint operation value, the reference data, and the like of the measurement object of the present invention refer to the amplitude (ie, the size) of the parameter, without limiting the description and/or additional description; of course, the measurement object itself may also be Time parameters, such as acceleration response time, deceleration response time, parameter change rate, etc.; for example, the measurement object can be either speed, rate of change of speed (ie, acceleration), or rate of change of acceleration (ie, jerk).

Model Method 1:

As shown in the subsequent embodiment: when the measured object is the mass of the elevator whose amplitude may vary greatly (such as m1, m2, it is obvious that the amplitude may vary greatly, referring to the time when different "elevators are controlled by the power unit" In the segment (that is, in different operating processes), the movement of people or goods into and out of the elevator may cause the quality of the elevator to change greatly. This parameter usually does not change during the current operation of the elevator (obviously, that is, when In the second operation process, the elevator quality value changes little or unchanged); the preferred method is to set the reference data according to the joint operation value obtained by performing the elevator operation energy balance calculation when the set condition is satisfied (and the key target is The actual value or the second permission range); that is, the joint operation value obtained by calculating the energy balance calculation of the elevator operation according to the actual value in the reference data and the second permission range according to the set condition set;

The technical solution is one of the core ideas of the present invention, because the elevator quality (m1, m2) of the elevator may vary greatly in each different operation process, and the self-learning mechanism can be established by using the technical solution. Automatically follow the normal change of the load and flexibly adjust the reference data (the key target is the actual value or the second permitted range); on this basis, the monitoring sensitivity can be improved and the adaptability to environmental changes can be improved. Obviously, during the operation period of “not satisfying the set condition” (that is, the majority of the running time of the elevator operation), it is naturally unnecessary to repeatedly set the reference data;

Demonstration method 2: When the measurement object is the elevator quality with fixed amplitude (such as m0, m3), the preferred method is to set the reference data by the preset value (for example, the system default value), the second permission range; that is, the reference The second permitted range in the data can be set according to the system default value; the set time of the reference data can be either before the elevator is run or when the system is powered on; obviously, before the elevator runs. "or not at the beginning of the current operation" (that is, the majority of the running time of the elevator operation); of course, the joint operation value obtained by the elevator operation energy balance calculation when the set condition is satisfied may be used as a reference. data.

Model Method 3:

When the measured object is untestable parameter and / or pre-settable parameters and / or system inherent parameters (such as rolling resistance coefficient, efficiency coefficient), this type of parameter is not easy to actually measure in the elevator operation, but this type of parameter is in the elevator The amplitude is relatively stable during normal operation, even if it changes There are also relatively stable rules (such as following speed, usage time, etc.); the reference data (the calibration value (ie, the reference value) is set according to the preset value (especially the system preset value (the system default value)), The first permission range and the second permission range of any one or more kinds of data are the simplest or simple manner; and the reference calculation value obtained by performing the elevator operation energy balance calculation when the set condition is satisfied may be used to set the reference data; That is, the calibration value and/or the second permission range in the reference data may be set according to a preset value (especially a system preset value (medium system default value));

The setting time of the reference data can be either before the elevator running or at the beginning of the current operation; when the measurement object is a system inherent parameter, the subsequent embodiment 8 is a reference example;

Model Method 4:

When the measurement object is any one of the parameter to be measured and/or the measurable parameter and/or the source dynamic parameter and/or the mechanical operation parameter whose amplitude may vary greatly: the preferred mode is set according to the measured value Reference data, the focus is on setting the actual value and/or the second permission range in the reference data; subsequent embodiment 9 and embodiment 10 are reference examples; (obviously, the amplitude may vary greatly, meaning even in the same "elevator" In the period of time when the power unit is controlled to operate (that is, in the same operation flow), the amplitude may vary greatly; in general, any one of the actual value and the second permitted range in the reference data may be Setting according to the measured value, and the time value of the reference data and the value of the joint operation value are within a preset time range (ie, synchronized);

When the measured object is any one of the parameter to be measured and/or the measurable parameter and/or the source dynamic parameter and/or the mechanical operating parameter, since the actual value or the second permitted range in the reference data may change rapidly, Therefore, the measured value of the measured object can be obtained, and the actual value or the second permitted range is set according to the measured value; and the time value of the reference data and the joint operation value is limited to a preset time range; the smaller the time range is, the smaller the time range is. Good; when the elevator speed is 12KM/H, the frequency is 200M per minute, about 3.3 meters per second, the difference can be 3.3 meters in 1 second, the difference of 10 milliseconds is 0.033 meters; the difference of 1 millisecond is 0.0033 meters; the setting of this time range can be Try to use the elevator energy transfer amount to handle the fastest CPU speed. For example, 100M single frequency can perform 100,000 single-cycle command operations within 1 millisecond;

Since the time value of the reference data and the value of the joint operation value need to be within a preset time range (ie, synchronization), it is obvious that when the time value of the reference data is out of the preset time range, Then, the reference data needs to be newly set to satisfy the condition that the value of the reference data and the value of the joint operation value are within a preset time range (ie, synchronization).

Model Method 5:

There is also a possibility when the measurement object is any one of the parameters to be measured and/or the measurable parameter and/or the source dynamic parameter and/or the mechanical operation parameter whose amplitude may vary greatly, according to which the measurement object is The history value sets the reference data; when the history value includes any one or two of the historical record original value and the historical record actual value, and the actual value or/and the second permitted range are set according to the data. When the value of the data is different from the current elevator operating condition, the difference between the elevator operating condition and the current elevator operating condition is lower than a preset threshold; that is, any one or more of the actual value and the second permitted range may be based on the measured object. The historical value is set, and the difference between the elevator running condition and the current elevator running condition when the historical value is taken is lower than a preset threshold;

The difference between the elevator running condition and the current elevator running condition when the value of the historical record value is lower than the preset threshold value refers to the elevator running condition corresponding to the historical record value generation (elevator mass, elevator speed, vertical acceleration, and The source power parameter) is consistent with the current elevator operating conditions (elevator mass, elevator speed, vertical acceleration, and source power parameters); obviously, the elevator operating condition refers to the type and magnitude of the parameters included in the input parameters; The agreement means that the parameters are the same or close, and if the parameters have directions, the directions of the parameters are the same or close.

For example, when the measured object is the source dynamic parameter, when the value of the joint operation value is similar to the elevator running condition when the value of a certain historical value is used (the values of the correlation factors of the energy transfer amount of the plurality of cores are similar; for example, the elevator The values of the mass value, vertical velocity, vertical acceleration and other parameters are similar), then the source dynamic parameter values of the two different time values may be similar; the specific elevator operating conditions (such as the core energy transfer condition correlation factor) The number of the data, the weight of each data, and the threshold of the degree of difference in the correlation factor of each energy transfer condition are set and adjusted by the user; the more relevant parameters, the more reasonable the weight setting, and the smaller the difference threshold is, the more the calculation/monitoring accuracy is. High; in general, the use of historical values to set the actual value of the rapidly changing measurement object provides a completely new technical choice, which makes up for the lack of ways that must be measured before.

Exemplary method 6: setting the reference data according to the historical record value of the measurement object;

The preferred method is: when the measurement object is any one of the source dynamic parameter, the mechanical operation parameter, the elevator quality, and the system inherent parameter (usually any elevator operation parameter), the first difference can be set according to the historical record difference. The scope of the license, that is, the first license range can be set according to the historical difference; for details, see "*** According to the historical value - technical solution for setting reference data" - Implementation Details

"*** According to historical value - technical solution for setting reference data" - Implementation details:

The present invention provides a technical solution for how to set reference data (second license range, first license range) using history values;

*_1. Principle:

Regardless of the type of measurement object, the principle of setting the throughput status identification value (that is, the second permission range) is usually as follows: the actual value of the measurement object is as close as possible to improve the sensitivity of the monitoring, but it must be The value is kept at a suitable difference to reduce the false trigger rate of the monitoring; if the upper limit of the energy transmission condition identification is set to 1.2 to 1.5 times the actual value, or the lower limit of the energy transmission condition identification value is set to 0.7 of the actual value. ～0.9 times, or the energy transfer condition recognition upper limit difference is set to 0.1 to 0.3 times the actual value, or the energy transfer condition recognition lower limit difference is set to the actual value (-0.3) to (-0.1) times;

*_2. General setting method:

However, the precise setting of the throughput status identification data (the second permission range and/or the first permission range), such as manual trial and error, or empirical method to slowly explore, to slowly verify, can deliver the amount of status The identification data has low adjustment accuracy and low efficiency; and the guide rails and/or elevator shafts and load conditions of different elevators are varied, which makes it more difficult to accurately set the identification data of the energy transmission condition.

*_3. According to the setting method of historical value:

Setting the reference data according to the historical record value of the measurement object (the key target is the energy transfer amount condition recognition difference or the energy transfer amount condition identification value) is one of the preferred methods;

*_4. Before the judgment of the energy delivery condition, reference may be made to the present invention (a processing method of elevator data), which has demonstrated how to set a history value; when the history value has been generated, Setting the reference data according to the historical record value (such as performing any one or more of the following steps 5B1, 5B2);

5B1. The historical record value includes a historical record original value and a historical record actual value, and the energy transfer amount status identification difference value is set according to a difference between the historical record original value and the historical record actual value (ie, a license range);

5B2. The historical record value includes a historical record original value, and the energy transfer amount status identification value is set according to the historical record original value;

*_5. The preferred way to set the reference data is as follows:

*_51. Set the actual value in the reference data according to the joint operation value obtained by performing the elevator operation energy balance calculation when the set condition is satisfied (this method is optimally applied to the elevator quality whose amplitude may vary greatly);

*_52. Set the difference in the amount of energy transfer in the reference data according to the preset history value (this method is basically applicable to most types of measurement objects, and the variable fuzzy control is precise control);

*_53. The combination of the two can get the ideal reference data, which can maximize the sensitivity of the abnormal transmission monitoring and reduce the false alarm rate of monitoring;

* According to the historical record value - the beneficial significance of setting the reference data: the technical solution is one of the core ideas of the present invention. When the measurement object is the elevator quality, the system inherent parameters (such as the rolling resistance coefficient, the efficiency coefficient), according to the measurement object The history value sets the reference data (the second permission range and/or the first permission range), and the parameter setting accuracy and the monitoring sensitivity can be hierarchically improved from the conventional fuzzy control to the precise control.

"5A5-(Technical Solution of Fuzzy Algorithm Value) - Implementation Details":

Setting reference data according to system default values, lack of flexibility; setting the reference data according to manual setting values, under-intelligent; presetting the reference data by a fuzzy algorithm is a preferred method; the fuzzy algorithm includes the following Any one or more fuzzy algorithm rules: statistically analyze the reference data that has been used most frequently according to a certain number of running times; or automatically select the reference data with the most selections in the most recent running times; or automatically select the last running reference Data; or set different weight index of each reference data (such as user presets the most valuable and most protective reference data) to set reference data; or comprehensive statistical analysis and weight index to set reference data;

"5A5-(Technical scheme of fuzzy algorithm value) - beneficial meaning": After the parameters are preset by the fuzzy algorithm, the intelligence of the system can be improved.

The subsequent energy transfer abnormality judgment/execution is usually performed after the reference data has been set, which simplifies the system.

Step A2: When the reference data has been set, step A3 can be directly executed; when the reference data is not set, the following steps must be performed to set the reference data: the joint operation value of m1 is obtained when the elevator runs at zero speed for 1.0 second. The set value m1_org is set; the upper limit deviation value m1_def_u and the lower limit deviation value -m1_def_d are set according to the historical record value calculated based on the elevator operation energy balance; and the upper limit value m1_ref1_u of the first reference value may be further set, the first reference The lower limit value of the value m1_ref1_d; m1_def_u and m1_def_d are both positive values, m1_def_u and m1_def_d are equal or inequitable; and a state information of "reference data has been set" is set; the first value is set according to the reference value and the permission deviation value. The formula of the reference value is as follows: m1_ref1_u=m1_org+m1_def_u, m1_ref1_d=m1_org-m1_def_d;

Alternate Embodiment 1 of Embodiment 9: The electromagnetic torque is used as the measurement object in Embodiment 9, and the other embodiments in the foregoing Embodiments 1, 2, 3, 4, and 5 and various alternative (or extension) embodiments may also be used. Any one of the dynamic parameters and the mechanical operating parameters is used as a measurement object, and the joint operation value is calculated. The reference value and the permission deviation value of the measurement object are set in the manner of step A2 in the embodiment 9, and refer to step A3 in the embodiment 9. The method of step B performs abnormal monitoring of the energy transfer condition of the elevator.

In Embodiments 6, 7, 8, and 9 and in the alternative or extension embodiments, the license deviation values are all based on system preset values or historical record values, and may be in a simpler manner, such as combining the measured objects. The calculated value or the reference value is multiplied by a coefficient as a permissible deviation value, which can be arbitrarily determined by the user depending on the on-site demand (for example, 0.1 or 0.3, etc.), or the first reference value is set according to the permissible deviation value, and the energy transfer condition is performed. Judgment and subsequent processing; or may not set the permission deviation value, the first reference value may be directly set, if the set upper limit value of the first reference value is greater than the actual value of the measurement object and less than the limit safety valve A value in the value; if the set lower limit value of the first reference value is a value smaller than the actual value of the measurement object.

In the monitoring method (#1) provided by the present invention, the preferred solution is that the values of all the parameters are acquired in real time, and the steps A and B are performed in real time, and are executed cyclically in a set time period, and the set cycle period is set. The shorter the better, the shorter the sensitivity and timeliness of monitoring. Of course, it can also be performed in non-real time or intermittently.

The value of the parameter (such as the joint operation value, the reference value in the reference data, the value of the input parameter required to calculate the joint operation value), and the acquisition time; the value of the parameter refers to the parameter generation time. Refers to the time corresponding to the value of the input parameter required to calculate the parameter; because there are multiple ways to acquire (read, measure, etc.); for example, the reading is generated 100 milliseconds before the time1 time. The value of the parameter is set to time1, but the time of the parameter is the first 100 milliseconds of time1.

In the monitoring method (#1) and/or the monitoring method (#1-2) and/or the monitoring method (#1-3) and/or the monitoring method (#1-4) of the present invention, when the measuring object is required In the case of measured parameters and/or measurable parameters and/or any of the source dynamic parameters and/or mechanical operating parameters, the preferred scheme is all parameters (eg joint operation values, reference values in reference data, calculation of joint operation values) The value of the required input parameter is taken in the preset time range (as much as possible), real-time calculation, real-time acquisition (read or measurement) joint operation value and reference data, real-time judgment, real-time disposal judgment result, At this time, the value of the parameter can be equal to the acquisition time;

In the monitoring method (#1) and/or the monitoring method (#1-2) and/or the monitoring method (#1-3) and/or the monitoring method (#1-4), when the measuring object is the elevator quality, When any one of the inherent parameters of the system is used, the preferred method of calculating the value of the joint operation value (along with the value of the input parameter required to calculate the joint operation value) is to take values within a preset time range (synchronize as much as possible) Real-time calculation, real-time acquisition (read or measurement), real-time energy transmission abnormality judgment/monitoring; but the reference data's value or set time does not need to be at the same time as the joint operation value; The acquisition time (just read) of the reference data before the abnormality judgment is transmitted is different from the value of the reference data.

The control method of the value of the parameter value 1: In the strict sense, it is inconvenient to obtain the values of multiple parameters at the same time; in the actual operation process, the value of each parameter group may have the value before and after. At this time, it is only necessary to control the value of each parameter to a preset time range, which may be determined according to the actual software processing speed and hardware response speed; if it is 100 milliseconds, Or 10 milliseconds, or 1 millimeter, or 0.1 millisecond; the shorter the preset time range, the higher the measurement/monitoring accuracy, but the system cost is also increased;

Control method of the value of the parameter value 2: If the elevator operating conditions are basically unchanged, for example, if the speed of the elevator is maintained at a constant speed of 1 m/speed within 10 seconds, the current value of the speed, or the first of the 10 seconds is taken. The value of the time is the same as the value at the end of the 10 seconds; therefore, the preset time range of the value of each parameter value can be adjusted according to the operating conditions of the elevator, that is, when the operating conditions of the elevator are unchanged. At this time, you can get the value of the parameter at any point in time when the operating conditions are unchanged.

The description of the value time and acquisition time of the above parameter values is applicable to any embodiment of the present invention.

In the present invention, the first reference value and the license deviation value may be set by a preset value of the system, and may be set in various manners, for example, by a limited number of experimental methods, a manual trial method, a type test method, and the like. set.

There are many ways to obtain the joint operation value of the measurement object. One is to read the joint operation value of the measurement object output by other devices, such as the OBD system of the elevator or the motor drive device to read the calculated joint operation value, only The joint operation value is calculated based on the elevator operation energy balance calculation formula;

There is also a way, through the integrated design system with the monitoring system, in the monitoring system provided by the present invention, according to the preset elevator running energy balance calculation formula, that is, the calculation rule of the elevator motion balance (including the table processing model, or mathematics) Calculating a formula), obtaining a value of an input parameter of the elevator; the input parameter is a parameter required to calculate a value of the measurement object according to the elevator operation energy balance calculation formula (that is, the input parameter is an energy balance of the elevator operation) Calculating all the parameters except the measured object in the formula; calculating the joint operation value according to the value of the obtained input parameter; the value of the input parameter is within a preset time range; The setting rule of the input parameter can be seen by the setting rule 1 of the foregoing input parameter;

The beneficial significance of this scheme: Allows the joint operation of the measurement object to be integrated with the monitoring system, which can greatly reduce the signal connection and transmission cost of the monitoring system and reduce the transmission error.

11. Further, in the monitoring method (#1) and/or monitoring method (#1-2) and/or monitoring method (#1-3) and/or monitoring method (#1-4), Determining whether the energy transfer condition of the elevator is abnormal according to the joint operation value and the reference data of the measurement object may include any one or more of the following 11A1, 11A2:

11A1. When the reference data is composed of the reference value of the measurement object and the permission deviation value of the measurement object, it is determined whether the difference between the joint operation value and the reference value exceeds the permission deviation value.

The beneficial effects of the solution: the technical solution can clearly realize the typical abnormality of energy transfer monitoring.

12. Further, in the monitoring method (#1) and/or monitoring method (#1-2) and/or monitoring method (#1-3) and/or monitoring method (#1-4), The setting of the reference data may include any of the following 12A1, 12A2, 12A3, and 12A4:

12A1. When the measurement object is any one of a carrier quality and a system inherent parameter, the reference value and/or the first reference value of the measurement object is calculated according to an elevator operation energy balance performed when the set condition is satisfied. And the obtained joint operation value is set;

12A2.

Implementation details of Scheme 12A1: see Examples 6, 7, 8 and alternative and/or extended embodiments thereof;

Implementation details of scheme 12A2: Under normal circumstances, the principle of setting the license deviation value of the measurement object is: the value needs to be as small as possible to improve the sensitivity of the monitoring, but not too small to reduce the false trigger rate of the monitoring; similarly, The first reference value is also set as follows: it is as close as possible to the reference value of the measurement object but must maintain a suitable difference with the reference value; if the upper limit value of the first reference value is set to 1.2 to 1.5 times the reference value Or the lower limit of the first reference value is set to 0.7 to 0.9 times the reference value, or the upper limit deviation value is set to 0.1 to 0.3 times the reference value, or the lower limit deviation value is set to -0.3 to -0.1 of the reference value. Times; but the precise setting of the reference data, such as manual trial and error method, or empirical method to slowly explore, to slowly verify, reference data adjustment accuracy is low, low efficiency; and different elevator operating conditions, The load conditions change a lot, which makes it more difficult to accurately set the reference data.

Setting the reference data according to the historical record value of the measurement object (the key target is the license deviation value or the first reference value therein) is one of the preferred methods;

When the historical record value has been generated, the reference data may be set according to a historical record value (such as performing any one or more of the following steps 9A2_1, 9A2_2, 9A2_3);

9A2_1. setting the permission deviation value according to a difference between the historical record original value and the historical record reference value;

9A2_3. setting the first reference value according to the historical record original value;

The common law in the above 9A2_1, 9A2_2, and 9A2_3 is to set a certain value 2 according to a certain value 1. In the present invention, a certain value 2 is set according to a certain value 1, and a value 1 can be directly assigned to a value of 2, or a certain value can be The value 1 is increased or decreased according to the situation, or the additional offset is set to a value of 2, which can be handled flexibly;

The preferred mode of the reference data setting is: setting the reference value in the reference data according to the joint operation value obtained by calculating the elevator operation energy balance performed when the set condition is satisfied; setting according to the preset history value The reference deviation value in the reference data can be combined to obtain ideal reference data, which can maximize the sensitivity of energy transmission abnormal monitoring and reduce the false positive rate of monitoring;

Implementation details of scheme 12A3: The fuzzy algorithm includes any one or more of the following fuzzy algorithm rules: statistically analyzing the reference data that has been used most frequently according to a certain number of running times; or automatically selecting the number of times of the most recent running selections The most reference data; or automatically select the most recent runtime reference data; or set different weight indices for each reference data (such as user presets Valuable and most protective reference data) setting reference data; or setting the reference data by comprehensive statistical analysis and weight index;

Implementation details of Scheme 12A4: see Example 9 and its various alternative and/or extended embodiments;

The beneficial significance of the scheme 12A1: the technical solution is one of the core ideas of the present invention, because the carrying quality of the elevator may vary greatly in each operation, and by adopting the technical solution, a self-learning mechanism is actually established, which can be automatically Flexibly adjust the reference data following the normal change of the load (the key target is the reference value or the first reference value); on this basis, the monitoring sensitivity can be improved and the adaptability to environmental changes can be improved;

The beneficial significance of the scheme 12A2: the technical solution is one of the core ideas of the present invention. When the measurement object is the elevator quality and the system inherent parameter, the reference data is set according to the historical record value of the measurement object (the key target is The permission deviation value or the first reference value can improve the parameter setting accuracy and the monitoring sensitivity hierarchically, from the conventional fuzzy control to the precise control.

The beneficial significance of scheme 12A3: the fuzzy algorithm preset parameters can improve the simplicity of the system;

The beneficial significance of the scheme 12A4: The scheme can be applied to the monitoring of the energy transmission anomaly when the object is measured as any of the source dynamic parameters and the mechanical operating parameters.

13. Further, the monitoring method (#1) and/or the monitoring method (#1-2) and/or the monitoring method (#1-3) and/or the monitoring method (#1-4) are also satisfied. Any one or more of the conditions 13A1, 13A2, and 13A3:

13A1. The measurement object is any one of a carrier quality and a system inherent parameter;

13A2. When the measurement object is any one of a carrier quality and a system inherent parameter, the joint operation value and the reference data are only derived from a parameter acquisition system, that is, both are energy balance according to elevator operation. Calculated

13A3. The energy transfer exception handling mechanism includes activating an energy transfer fault monitoring mechanism.

The beneficial significance of this 13A1 program:

Taking the source dynamic parameters (such as the tension of the wire rope, the output torque of the traction sheave, the electromagnetic torque, the current, the electrical power, etc.) or the mechanical operating parameters (such as speed, acceleration, etc.) as the measurement object is the worst monitoring solution, measurement and control The difficulty/cost is high, and the accuracy/performance is also reduced; the magnitude of the measured joint operation value of the measuring object may change rapidly to increase the measurement error of the first incentive, and usually the actual measured value or the command value needs to be acquired to set With reference data, the reference data amplitude may also change rapidly to bring the measurement error of the second incentive; and because the joint operation value and reference data may be in a low amplitude state (relative to full scale measurement), it is more likely to cause the third cause. Measurement error, even monitoring failure; because the quality of the load may vary greatly in different operational processes, if the source dynamic parameters or system operating parameters are used as the measurement targets, the value of the carrier mass must be obtained first, resulting in the measurement of the fourth incentive. Errors and make the measurement/monitoring system more complicated/high cost;

The measurement object is preferably a carrier quality, and the carrier quality value is relatively stable in the current operation of the elevator, and is convenient for the elevator occupant or the supervisor to visually judge the monitoring effect, thereby greatly improving the monitoring reliability;

The sub-optimal object of the measurement object is the inherent parameter of the system (especially the efficiency coefficient); the efficiency coefficient substantially represents the wear condition of the elevator component, The safety condition of the machine, and the parameter has little change in the amplitude of the elevator operation, and it is easy to measure and compare; however, this method also has the measurement error of the fourth incentive mentioned above, and it is not convenient for the elevator operator to visually judge the monitoring effect;

The beneficial significance of the 13A2 solution: as described in the background art, a typical parameter acquisition system has a class A car inner sensor weighing system, a class B car outer sensor weighing system, and a class C inverter weighing at zero speed. System, in the prior art, also a method for judging whether a sensor weighing system is faulty by a combination of class AB and class C technology, which greatly increases the cost by using a multi-way weighing system at the same time; The method for calculating the operating parameters of the elevator (ie, the acquisition method) and the system can allow parameter estimation and operation safety monitoring to be implemented using only one parameter acquisition system (such as any sensor outside the car or the inverter). Significantly reduce the cost of the monitoring system; especially the motor drive (such as frequency converter) for parameter calculation (including weighing), can greatly reduce the elevator safety monitoring cost.

The beneficial significance of this 13A3 scheme: after the abnormality of the energy transmission condition occurs, the operator is alerted to the alarm/timely treatment by starting the energy transmission fault monitoring mechanism. If an energy transfer abnormality occurs, the voice and/or light indication system is activated immediately to alert the operator and to report the troubleshooting of the energy transfer abnormality.

14. Further, the monitoring method (#1) and/or the monitoring method (#1-2) and/or the monitoring method (#1-3) and/or the monitoring method (#1-4) further include the following Any one or more of 14A1, 14A2, 14A3:

14A1. Determine, according to the acquired joint operation value, the reference data and the operating environment information, whether an energy transfer fault condition in an energy transfer abnormality occurs;

14A2. outputting and/or saving the value of the carrier quality;

14A3, restarting the energy transmission fault monitoring mechanism when the energy transfer of the elevator is detected to be abnormal;

The implementation details of the 11A1 program are as follows:

The operating environment information is also the external environment information. The abnormality of the running environment information means that the value of the information exceeds the preset normal range.

Abnormal energy transmission usually includes abnormal operating environment of the elevator, energy transmission failure, etc.; typical abnormal operating environment of the elevator includes abnormal conditions of the load (such as jumping or sharp shaking in the elevator/abnormal rolling of the item);

There are two ways to identify and deal with energy transfer faults. One is to use the 14A1 scheme to directly determine whether an energy transfer fault occurs according to the joint operation value, reference data, and operating environment information. The 14A1 scheme can also be called synchronous energy transfer fault monitoring. mechanism;

The second is to adopt the 14A3 scheme, and then restart the energy transmission fault monitoring mechanism when the energy transmission abnormality of the elevator has been detected, and the 14A3 scheme may also be referred to as a progressive energy transmission fault monitoring mechanism;

If the measured external environmental information is normal and an energy transfer abnormality occurs, the elevator can be directly determined to be in an energy transfer fault condition; if the measured external environmental information has an abnormal condition and an energy transfer abnormality occurs, the current energy of the elevator can be determined. The transmission anomaly may be caused by the external environment; the elevator may continue to issue the energy transmission abnormal warning information instead of the energy transmission failure information; at the same time, the elevator may continue to perform the monitoring operation to determine whether the energy transmission abnormality is eliminated with the elimination of the operating environment abnormality, if it is not possible to synchronize If the elimination or energy transfer abnormality continues to be longer than the set time, the energy transfer failure can still be determined;

Whether the elevator operating environment is abnormal, the identification and judgment can be made by acquiring (reading or measuring) the operating environment information of the elevator; the operating environment information can be obtained in various ways: through relevant vibration sensors, optical, ultrasonic, infrared sensors, radar The device measures the identification; the operator can also distinguish the above situation by visual recognition; the time value of the joint operation value and the value of the operation environment information are within a preset time range.

The energy transmission failure mainly includes: the frictional force between the object and the car in the guide rail and/or the elevator shaft is abnormal or the abnormality of the personnel being caught in the elevator shaft, the abnormal rotation of the rotating parts of the elevator, aging, bursting, breaking, the rotor holding shaft of the motor, etc.; The energy transfer fault monitoring mechanism of the elevator confirms that an energy transfer fault occurs, and an emergency treatment scheme such as deceleration, shutdown, fault alarm, or reverse operation is usually required to be started immediately.

The beneficial significance of this 14A1 scheme: through the energy transmission fault monitoring mechanism, it is possible to more deeply identify the cause of the formation of the abnormality of the energy transfer (whether the operating environment is abnormal, or whether the energy transmission fault), thereby facilitating a more appropriate security processing response. (If the energy transfer is abnormal due to the jump of the person in the elevator, only need to give a voice prompt or warning, such as slowdown, stop or even reverse due to energy transmission failure).

The beneficial significance of the 14A2 solution: regardless of the type of the object to be measured, at any time, the value of the carrying quality is output (to the man-machine interface in the car and/or the man-machine interface of the hall door), which helps the elevator passenger to glance at the eye. Identifying whether the elevator is running normally is of great significance for the safe operation of the elevator;

The joint operation value of the quality of the carried item is saved, like the black box function of the aircraft safety, which is convenient for post-mortem analysis.

According to the foregoing description of the source power combination type parameter, the electric power can combine the electrical energy; the invention also allows the use of the energy type of the source power combination type parameter (such as the power consumption of a certain period of time, or the sum of work of a certain period of time) As a measurement object; power and energy are easily confused from physical concepts, but for elevator operation, the meaning of the two is different; power is the differentiation of energy versus time, with the concept of instant-fast, energy is the power in time. Accumulation, with the concept of time delay-slow speed; therefore, using the scheme provided by the present invention to perform abnormality monitoring of energy transmission, it is preferable to use instantaneous values of source power parameters (such as instantaneous power, instantaneous torque, instantaneous driving force, instantaneous current, etc.) Perform real-time energy transfer anomaly monitoring; if energy source type combined power parameters are used for energy transfer anomaly monitoring, the time required to accumulate energy should be as small as possible (eg, 100 mm, 10 msec, 1 msec, 0.1 mm). ).

If the source-power combination parameter of the energy type is used as the measurement object for the energy transfer abnormality, the core parenthesis step is also required (acquiring the joint operation value of the measurement object, setting the reference data, and judging the energy transfer condition based on the joint operation value and the reference data) Whether the abnormality or the judgment result of the energy transfer condition has a clear treatment scheme can be referred to the following embodiment 10:

Example 10 of monitoring method (#1) and/or monitoring method (#1-2) and/or monitoring method (#1-3) and/or monitoring method (#1-4): including steps A, B, C;

Step A: This step includes step A1, step A2, and step A3;

Step A1: Referring to the method of the foregoing Embodiment 5, the energy flow of the elevator is identified to the working condition (electrical ascending, motor braking up, electric down, motor braking down), and the speed change status of the elevator is recognized (non-zero uniform speed operation, acceleration operation) , slow down operation), first Take (read or measure) parameters in the same time range (motor efficiency coefficient Ke1 and / or Ke2, mechanical transmission system efficiency coefficient Km1 and / or Km2, integrated gear ratio im, no-load car mass m0, pair The values of the weight mass m3, the uplink speed V1, and the downlink speed V2) are calculated according to different energy flow directions and speed changes, and any one or more of the following 10A1-1, 10A1-2, and 10A1-3 are calculated, and the calculation is performed. The joint operation value Pm_cal of the electrical power of the motor is calculated as follows:

10A1-1. When the energy flow direction is electric up, and the speed change condition is non-zero constant speed operation, calculate the joint operation value Po_cal of the electric power of the motor according to the following formula 4-26;

Po_cal=((m1+m0)*g-m3*g)*V1/Kem1, (Equation 4-26);

10A1-2. When the energy flow direction is electric down, and the speed change condition is non-zero constant speed operation, calculate the joint operation value Po_cal of the electrical power of the motor according to the following formula 4-27;

Po_cal=(m3*g-(m1+m0)*g)*V2/Kem1, (Equation 4-27);

10A1-3. When the elevator is motor brake up + non-zero constant speed operation, calculate the joint operation value P4_cal or the resistance energy consumption braking power P5_cal of the power generation feedback braking power according to the following formula 4-28;

P4_cal=(m1+m0)*g-m3*g)*V1*(K14*Kem2), (Formula 4-28-1);

P5_cal=(m1+m0)*g-m3*g)*V1*Kem2, (Equation 4-28-2);

10A1-4. When the elevator is motor brake down + non-zero constant speed operation, calculate the joint operation value P4_cal or the resistance energy consumption braking power P5_cal of the power generation feedback braking power according to the following formula 4-29;

P4_cal=(m3*g-(m1+m0)*g)*V2*(K14*Kem2), (Equation 4-29-1),

P5_cal=(m3*g-(m1+m0)*g)*V2*Kem2, (Formula 4-29-1);

Further, the joint operation value Po_cal or P4_cal or P5_cal is calculated (for example, integrated) to obtain an electrical energy value EM1_cal within 2 seconds, and EM1_cal is an indirectly obtained joint operation value;

Step A2: Obtain the Pm_cal and EM1_cal values, obtain the electrical power reference value Pm_r (read the data measured by the motor driver or measure with the power meter), and then integrate the Pm_r operation to obtain the electrical within 2 seconds of the EM1_cal period. The measured value of the energy EM2, or directly measured by the active electricity meter to obtain the EM2 value; EM2 as the reference value in the reference data; set the permission deviation value EM_def3: EM_def3 = EM2/10, or EM_def3 = EM1_cal / 8;

Step A3: Perform one or more of the following two energy transfer condition determination conditions: judgment condition 1: ((EM1_cal-EM2)>EM_def3), judgment condition 2: ((EM1_cal-EM2)<(-EM_def3)) ,

Step B: If any of the two energy transfer condition determination conditions in step A3 is YES, the energy transfer abnormality processing mechanism (such as voice alarm, etc.) is started;

Alternative 1 of Embodiment 10: The time period of energy calculation can be set from 2 seconds to 1 second, 0.1 second, 0.01 second, etc.; the longer the time, such as more than 5 seconds and 10 seconds, etc., the loss of energy transmission abnormal monitoring is lost. Meaning; the shorter the time, the faster the energy transmission anomaly monitoring response, but the larger the measurement error (due to the four incentives) of the joint operation value, the measured value, and the reference data, the worse/the effect is worse; It can be seen that the source power parameter or the combination of source and power parameters (such as energy) as the measurement object of the energy transmission anomaly monitoring effect is far less than the carrier quality or system inherent parameters as the measurement object.

Example 11 of monitoring method (#1) and/or monitoring method (#1-2) and/or monitoring method (#1-3) and/or monitoring method (#1-4):

Obtain the joint operation value of the elevator's elevator quality (operating conditions: two shifting operations, ignoring the windage change and the default power plant operating condition is to accelerate the upward movement):

M2=(fq2-fq1)/(a2-a1)+m3; (Formula A3-4-3);

M1=m2-m0;

Fq2 and a2 are the comprehensive tensile and vertical acceleration of the wire rope obtained at time2, and the electromagnetic torque obtained when Te2 is time2; fq2=Kem1(Te2*im/R1)

Fq1 and a1 are the comprehensive tensile and vertical accelerations of the wire rope obtained at time1, and the electromagnetic torque obtained when Te1 is time1; fq1=Kem1(Te1*im/R1)

M2=(Kem1(Te2-Te1)*im/R1)/(a2-a1)+m3; (Formula A3-4-4);

Example 12

Obtain the joint operation value m2 of the elevator elevator quality; (the operating condition is: ignore the wind resistance change and the default power plant operating condition is the power unit driving state):

M2=((P2o_2/Vq2)-(P2o_1/Vq1))/(a2-a1)+m3;

Among the above parameters, P2o_1, Vq1, and a1 are the electric power, vertical speed, and vertical acceleration obtained when tim1 is respectively; P2o_2, a2, and Vq2 are elevator operating parameters (electric power, vertical speed) obtained when tim2 is different from tim1 time point. , vertical acceleration); and a2≠a1;

In the above energy transfer monitoring method and system, the system is allowed to switch the measurement object according to the need, and even multiple measurement objects are enabled at the same time, and multiple energy transfer status judgments of multiple different measurement objects are performed; if the carrier quality is allowed as the measurement object The energy transfer condition is judged and monitored. At the same time, the rolling friction resistance coefficient is used as another measurement object to perform another energy transfer condition judgment and monitoring. As long as any energy transfer condition judgment result is an energy transfer abnormality, the energy transfer abnormality processing mechanism is started. ;

In the monitoring process, the system is also allowed to switch the source dynamic parameters. For example, when the elevator is running at low speed and high torque, the torque type parameter (such as electromagnetic torque) can be used as the source power parameter; for example, when the elevator runs at high speed and low torque, The power type parameter (such as motor power) can be used as the source power parameter to improve the calculation accuracy of the joint operation value of the measurement object and improve the sensitivity of the energy transmission abnormality monitoring;

It is also allowed to use the same measurement object to simultaneously measure the multiple joint operation values of the same measurement object by using multiple source dynamic parameters, and perform multiple energy transmission status judgments and monitoring; for example, taking the item mass m1 as the measurement object, The integrated tension force F1 of the wire rope is used as the source power parameter to construct an energy transmission condition judgment and monitoring #100 system, and the system can mainly monitor the abnormality of the friction between the object and the car in the guide rail and/or the elevator shaft (if the person is stuck in the car) When it is in contact with the elevator shaft, the frictional force f0 will increase. At the same time, using the power input electric power P3i as the source power parameter to construct another energy transfer condition judgment and monitoring #101 system, the system can simultaneously monitor the elevator power supply device, the motor drive, the motor and the rear mechanical transmission system; Only enable the #100 system (not enabled #101 system) monitoring motor and rear mechanical transmission system, then you can directly verify the energy transmission status of the elevator power supply unit and motor driver with P3i and motor electric power Pm and efficiency coefficient k31. The verification method is to determine whether ((P3i*k31)-Pm) is greater than a preset threshold (such as P3i/20), and if it is greater than, the power supply device or the motor driver is abnormally operated;

In general, based on the monitoring method and system (#1) of the elevator lifting operation provided by the present invention, according to the energy transfer principle of the elevator, the layer-by-layer or multi-layer energy transmission abnormality monitoring is performed, and the elevator can be When the operating parameters do not exceed the safety limit threshold, it is convenient to carry out all-round sensitive and accurate protection of the overall power system and mechanical transmission system of the elevator.

The degree (such as half or execution completion) as a point in time to start the monitoring method (and / or monitoring system) or directly start the monitoring method (and / or monitoring system) with the start command sent by the other applications . In the working mode initiated after receiving the manual operation instruction, the operation instruction is used to control the monitoring method (and/or the monitoring system) to start operation, which is an operation button, a touch screen or other mobile electronic device in the car. (such as mobile phones), etc. are generated after human operation.

Benefits of monitoring method (#1) and/or monitoring method (#1-2) and/or monitoring method (#1-3) and/or monitoring method (#1-4) provided by the present invention and corresponding systems :

The invention deeply analyzes the structure and working principle of the counterweight elevator: the operation of the elevator is essentially the energy transfer process, that is, the transmission process of the power driving the elevator; the monitoring method (#1) and/or provided by the present invention Step A of the monitoring method (#1-2) and/or the monitoring method (#1-3) and/or the monitoring method (#1-4) includes the steps of: obtaining an energy balance based on the elevator operation of the measurement object of the elevator Calculating the joint operation value; in the elevator operation energy balance calculation of the elevator operation, the elevator source power parameter represents the power supply information, the elevator quality represents the most basic attribute of the power receiver, and the elevator system operation parameter represents the basic condition of the energy transfer (eg The inherent parameters of various systems) and the mechanical operating parameters generated by the elevator under the action of power, that is, the motion results (such as speed, acceleration, etc.);

If the friction between the object of the elevator and/or the object in the elevator shaft increases with the car (including the reason that the person is stuck between the car and the elevator shaft): If the monitoring system uses the source dynamic parameters as the measurement object, Then, when other related elevator operating conditions (such as elevator quality, speed, acceleration, etc.) are constant, it is necessary to consume more power and cause the joint operation value of the reference value of the source power parameter and the elevator running energy balance calculated by the elevator. If the monitoring system uses the speed in the mechanical operating parameters as the measurement object, such as the reference value of the source power parameter of the elevator and other related elevator operating conditions (such as elevator quality, acceleration, etc.), The deviation between the reference value of the elevator speed and the joint operation value calculated by the elevator operating energy balance of the elevator may be increased; if the elevator quality (such as the mass of the carried item m1 or the total mass m2) is used as the measurement object and other related When the elevator operating conditions (such as acceleration) are constant, the joint operation value of the elevator mass calculated by the elevator running energy balance calculation of the elevator operation is changed; therefore, by comparing the joint operation value of the measurement object with the reference data, Determining whether the energy transfer condition in the operation of the elevator is abnormal, and the process step after the subsequent energy transfer condition determination can timely realize the abnormality monitoring and early warning of the energy transfer;

In the present invention, the state is also the condition, and both are equivalent; the energy transfer state is the energy transfer state.

Because the elevator source power parameter represents the supply information of the power, that is, the condition of the electric power system of the elevator (depending on the collection point of the specific electric power parameter group signal, the condition of the power supply device of the elevator, the motor driver, and the device in the motor); The system operating parameters of the elevator represent the basic conditions of energy transfer (such as various system inherent parameters), the relevant electrical efficiency coefficient reflects the safety status of the electric power system, the mechanical transmission component efficiency coefficient reflects the safety condition of the mechanical transmission components, and the personnel are stuck. Between the entrance car and the elevator shaft, the friction between the object of the elevator and/or the object in the elevator shaft and the car can be reflected. Obviously, the energy transmission condition in the present invention, that is, the condition of the energy transfer system, especially The condition of the energy transfer system directly related to the rise or fall of the elevator, that is, the condition of the energy transfer system that drives the elevator to run up and down; the energy transfer condition is a condition closely related to the safety of the elevator operation; not limited to the car only The condition of the device, the car inside the device generally does not drive the elevator to run Connection relationship; apparent energy transfer elevator situation, i.e. operating conditions of the power transmission member to be monitored elevator, the preferred operating conditions refer to wear and / or safety conditions.

In general, determining whether the energy transfer condition of the elevator is abnormal according to the joint operation value and the reference data of the measurement object is very important for improving the operational safety of the energy transfer system of the elevator; Exceeding the judgment of the failure of a similar device such as a load cell.

Because the reference data is set based on the reference value of the measurement object (not based on the safety limit threshold), it is allowed to be much smaller than the safety limit threshold; therefore, when the elevator operation parameter does not exceed the safety limit threshold, it is also easy to implement (including The reason that the personnel is stuck between the car and the elevator shaft is that the elevator energy transmission is abnormally monitored and early warning, so as to avoid the occurrence of more serious and unpredictable safety accidents (including wire rope breakage, elevator runaway, etc.); The diagnosis of cancer in human medicine, if it is found in the late stage, usually means the end of life. If the early detection usually means normal life, the technical solution is of great significance for the safe operation of the elevator.

The implementation of this monitoring method (#2):

The technical solution of the invention 23A is mainly to provide a weighing scheme of a motor driver (such as a frequency converter); the motor driver is weighed, and can be divided into a zero speed running weighing of the motor driver and a non-zero speed running weighing of the motor driver; The motor driver is not zero-speed running weighing, and it is necessary to identify the energy flow of the elevator to the working condition. The specific implementation can be referred to the foregoing embodiment 4; the non-zero speed running weighing of the motor driver can be performed only when a certain setting condition is met (such as an elevator). Weighing for 0.5 seconds, or moving 0.5 cm, etc.) can also be performed in the whole process; in other embodiments, the monitoring method may also include the step of obtaining the joint operation value of the quality of the carried item of the elevator in 23A, and judging The solution adopted thereafter is not limited to 23B11, 23B12, and other solutions may be employed, which are only preferred embodiments. The core of the scheme is to determine whether the joint calculation value of the quality of the carried goods of the elevator is greater than the rated load of the elevator to determine whether it is overloaded. The quality of the carried item belongs to a parameter in the quality of the elevator, and the joint operation value is calculated according to the parameters including the system operating parameter and the source dynamic parameter of the elevator.

The brake system can be divided into a rigid brake system and a flexible brake system; the rigid brake system of the present invention means that the magnitude of the brake torque of the brake system cannot be actively hierarchically controlled, that is, the brake system is only divided. Performing two actions of holding the brake and releasing the brake; the flexible brake system of the present invention means that the magnitude of the brake torque of the brake system can be actively and hierarchically controlled, and the brake torque level can be divided into two levels or Above; the change of the brake torque caused by the fluctuation of the external power supply (or voltage) of the brake system cannot be called active grading control, which belongs to passive control; the active grading control of the amplitude of the brake torque can be passed through IGBT, thyristor, The MOS tube is realized by adjusting the voltage and current of the PWM pulse width, and the voltage can also be adjusted by the multi-output transformer. For example, the transformer has multiple output poles, and can output various coil voltages such as 100%, 70%, 30%, etc. Brake torque

A more optimized method for zero-speed operation of the motor drive: in the above-mentioned method of zero-speed operation of the motor drive, the brake system releases the brake to a flexible release brake, once the elevator car is vertically displaced When the standard exceeds the standard, the brake can be quickly re-braked immediately; the flexible release brake of the present invention refers to grading and gradually reducing the brake torque; thereby improving the safety of the system and improving the comfort and safety of the passenger riding the elevator;

The invention provides an elevator load monitoring method (#2) and the beneficial effects of the system:

In the prior art inverter weighing scheme, due to lack of research on the energy flow direction of the elevator, the weight cannot be calculated when the elevator is running at a non-zero speed; the prior art is based on the overload monitoring of the car sensor weighing. The invention has high cost/complex structure; the monitoring scheme based on the motor driver (such as frequency converter) weighing elevator load provided by the invention has great significance for omitting the traditional sensor weighing system and reducing the weighing cost of the elevator;

In the prior art of the elevator, since the method of weighing the sensor in the car is usually adopted, the weighing result can only detect whether the overload is performed before the elevator runs, and it cannot reflect the friction and drag of the object and the car in the guide rail and/or the elevator shaft. The safety condition of the guide wheel, motor, intermediate transmission parts and motor drive has no practical significance for the safety monitoring of the elevator in the vertical lifting operation of the elevator; however, if the motor drive weighing technical scheme is adopted, the quality of the carried item will be at any time. The numerical output (to the man-machine interface in the car) helps the elevator passengers to recognize whether the elevator is running normally or not, and helps the non-professional elevator passengers (without the use of professional and professional equipment) to be quick and easy. Identify elevator operational safety information (this information may include rails and/or objects in the elevator shaft) The friction with the car, the traction sheave, the motor, the intermediate transmission components, and the safety of the motor drive are of great significance for the safe operation of the elevator.

Technical question four:

The fourth technical problem to be solved by the present invention is to provide an elevator control method for improving the operating efficiency of the elevator, that is, to provide a control method for the elevator operating efficiency, so as to improve the efficiency of the elevator operation under the premise of safe operation;

28. The present invention also provides a control method for an elevator, which can be used to improve the operating efficiency of the elevator, including the following steps:

The mechanical operating parameter of the elevator is pre-set with at least two different grades, the grade of the mechanical operating parameter is selected based on a parameter including at least the mass of the carried item of the elevator; or; based on the mass of the carrying item including at least the elevator The parameter calculates a joint operation value of the mechanical operating parameter, and the mechanical operating parameter has at least two joint operation values of different sizes when the mass of the carried item varies from zero to the rated load;

The elevator operation is controlled according to the joint operation value or the grade of the mechanical operation parameter; the mechanical operation parameter includes any one or more parameters of an uplink speed, a downlink speed, an acceleration when the uplink is accelerated, and an acceleration when the vehicle is decelerated.

In the control method, the at least two differently sized joint operation values or at least two different grades have two meanings: the first one is a finite joint operation value or grade greater than or equal to 2, which is equivalent to According to the finite joint operation value or grade, the corresponding quality of the carried item is divided into a plurality of parts, each part corresponds to a running speed and/or acceleration; the second type is an infinite number of values greater than or equal to 2, at this time carrying The quality of the item corresponds to the speed and/or the value of the acceleration, and the elevator is now steplessly regulated.

Each grade of the mechanical operating parameters of the elevator has its corresponding value, which is simply referred to as the corresponding value. Selecting a certain grade also selects the corresponding value of a certain grade; the above selection of the grade of the mechanical operating parameter is also based on the carrier including at least the elevator. After the parameters such as the quality of the item are calculated, the grade of the mechanical operating parameter is selected; since the grade of the mechanical operating parameter is calculated according to other types of data (the quality of the carried item, etc.), or calculated by a formula or a look-up table, the mechanical operating parameter is The corresponding value of a certain grade is a joint operation value;

In the control method, regardless of "calculating the joint operation value of the mechanical operation parameter" or "calculating the grade of the mechanical operation parameter after calculation", the calculation is based on parameters and presets including at least the quality of the carried item of the elevator. Mapping relationship calculation; specific mapping relationship, as described later.

In the control method: “control the elevator operation according to the joint operation value or grade of the mechanical operation parameter”; includes two cases, one is controlled in the control system implementing the control method, and the other is outputting the mechanical operation The joint operation value or grade of the parameter to control the elevator operation to the external control system;

The “controlling the elevator operation according to the joint operation value or the grade of the mechanical operation parameter” includes two implementation manners; one is to use the joint operation value of the mechanical operation parameter or the corresponding value of the grade as the preset value of the instruction To control the elevator operation; the other is to use the joint operation value of the mechanical operation parameter or the corresponding value of the grade as the operation upper limit threshold to control the elevator operation; The control method is described in detail later.

In the control method, the joint operation value of the mechanical operation parameter for controlling the operation of the elevator or the corresponding value of the grade cannot be greater than the safety value of the mechanical operation parameter;

Description of the safety value of the mechanical operating parameters: Because when the mechanical operating parameter is speed, the speed has various working conditions such as electric up, electric down, motor brake up, motor brake down, etc.; The upward speed and the upward speed of the motor brake ascending; the downlink speed is divided into the down speed of the electric down and the down speed of the motor brake down; when the mechanical operating parameter is the acceleration, the acceleration has an acceleration up, a deceleration down, and an acceleration down. , deceleration and other various working conditions:

Therefore, according to a plurality of different working states, the safety value of the mechanical operating parameter is a permissible value of the upward speed when the electric motor is up, the permissible value of the downward speed when the electric motor is going down, the permissible value of the upward speed when the motor is braking, and the motor. At least one of an allowable value of the downward speed at the time of braking, an absolute value of the allowable value of the acceleration of the acceleration in the upward direction, and an absolute value of the allowable value of the acceleration at the time of the deceleration;

The absolute value of the allowable value of the acceleration at the time of deceleration ascending and the absolute value of the permissible value of the acceleration at the time of accelerating the downward direction are related to the weight of the weight m3 and are not directly related to the quality of the carried item;

In the above control method, the safety value of the mechanical operating parameter is calculated according to a parameter including at least the mass of the carried item (preferably the current actual value) and the source dynamic parameter (preferably a safety limit threshold); the mechanical operating parameter The calculation of the safety value can be calculated at any time before the elevator is controlled, either in the internal system or in the external system; if it is done in an external system, only the result needs to be read. For example, the result is read from the second associated table and the first associated table described later; the emphasis is not on the calculation process, but on the approval of the result: only the value of the mechanical operation parameter for controlling the operation of the elevator is not greater than the safety value or the mechanical operation parameter. The corresponding value of the grade is not greater than the security value;

29. Preferably, in the above control method, the “controlling the elevator operation according to the joint operation value or the grade of the mechanical operation parameter” is: the joint operation value of the mechanical operation parameter or the corresponding value of the grade is used as an instruction pre- Set the value to control the elevator operation.

30. Further, in the above control method, the preset value of the upward speed of the elevator at the time of light load or heavy load is smaller than the preset value of the upward speed when the load is balanced; and/or: at the time of light load or under heavy load The preset value of the line speed command is smaller than the command preset value of the down speed at the time of load balancing;

31. Further, the parameter calculation based on the quality of the carrier item including at least the elevator is specifically calculated according to parameters including at least the quality of the carried item of the elevator and the source dynamic parameter of the elevator;

32. Further, in the control method described in the above 31, the calculation is an elevator operation energy balance calculation; and the elevator operation energy balance calculation is associated with an elevator operation direction.

33. Further, in the control method described in the above 32, the elevator operation energy balance calculation satisfies any one or more of the following conditions 33A1, 33A2, 33A3, 33A4, and 33A5:

33A5. When the source dynamic parameter included in the elevator operation energy balance calculation is an electric power parameter or a dynamic parameter of the mechanical rotary member, the parameters participating in the calculation of the elevator operation energy balance include friction correlation data of the mechanical rotary member.

34. Further, in the control method according to any one of the above 29-32, any one or more of the following conditions 34A1, 34A2, and 34A3 are also satisfied:

34A1. The value of the quality of the carried item is calculated based on electrical power parameters;

35A2. Outputting the value of the quality of the carried item to a human machine interface of the car and/or a human machine interface of the hall door and/or a human machine interface of the control center;

35A3. The elevator running energy balance calculation is specifically: obtaining a value of an input parameter of the elevator, where the input parameter is a parameter required for calculating an operation value of the elevator operation energy balance, such as performing an energy balance calculation of the elevator operation The required source dynamic parameters, system operating parameters, etc.; the combined operational values are calculated based on the values of the acquired input parameters.

The implementation of this control method:

The core content of this control method (1):

It is shown how to calculate the safety value of the mechanical operating parameters for controlling the operation of the elevator based on parameters including at least the quality of the carried item (preferably the current actual value) and the source dynamic parameter (preferably the safety limit threshold).

The calculation or acquisition of the security value, preferred embodiment 28A includes the following 28A-1, 28A-2 schemes:

(One 1)

The 28A-1 implementation is as follows:

The carrying quality is the mass of the carrying item, and the value of the quality of the carrying item may be the current actual value or a preset value; because the core purpose of the control method is to set the machine for controlling the running of the elevator according to the current actual value of the carrying quality. The safety value of the operating parameter is increased to improve the operating efficiency of the elevator, so the value of the carrying quality is preferably the current actual value, and the current actual value is preferentially calculated based on the electric energy parameter based on the operating energy balance of the elevator; of course, the current The actual value also allows the energy balance calculation of the elevator operation from other source dynamic parameters, and also allows the sensor to weigh the gain, but the latter two methods will raise the cost;

The value of the source dynamic parameter, preferably the safety limit threshold of the source dynamic parameter, is calculated in conjunction with the current actual value of the carrier mass, so that the maximum operating efficiency of the elevator is facilitated; or the value less than the safety limit threshold may be selected. Will not be conducive to improving efficiency;

By in-depth study and analysis of the structure of the counter-elevator, referring to the foregoing embodiment 4, the calculation formulas of the following formulas 28-1, 2, 3, 4, 5, 6, and 7 can be obtained; Po_ena is the permissible value of the motor power, and Te_ena is Permitted value of electromagnetic torque, P4_ena is the permissible value of the power generation braking power, P5_ena is the safety limit threshold of the energy consumption braking power, and F1_ena is the permissible value of the comprehensive tension of the wire rope;

The above-mentioned many permitted values are safety limit thresholds that can be set according to the elevator model and site requirements;

Calculating the allowable value of the uplink speed V1_ena and/or the allowable value of the downstream speed V2_ena according to the permission value of the power type (such as Po_ena or P4_ena or P5_ena) and according to different energy flow conditions (or together with the speed operating condition);

The absolute value aj_ena of the permissible value of the acceleration is calculated according to the permissible value of the force or torque or instantaneous power type (eg F1_ena) and according to the different energy flow conditions (or together with the speed operating conditions); The suffix _ena indicates that the parameter is a security value or a license value preset by the system.

(minus 2)

When the mechanical operating parameter is an upstream speed or a downstream speed, the preferred scheme 28-1 is as follows:

The permissible value of the upward speed of the electric uplink is calculated according to the permissible value of the electric power of the electric system in the electric state, and the following formula 28-1 can be obtained by referring to the above formula 5-1:

V1_ena=Kem1*Po_ena/((m1+m0)*g-m3*g), (Equation 28-1);

The permissible value of the downward speed of the electric motor is calculated according to the permissible value of the electric power of the electric system in the electric state, and the following formula 28-2 can be obtained by referring to the above formula 5-2:

V2_ena=Kem1*Po_ena/(m3*g-(m1+m0)*g), (Equation 28-2);

Calculate the permissible value of the upward speed when the motor brakes up according to the safety limit threshold of the power generation feedback power and/or the energy consumption braking power. Refer to Equation 5-3 above to obtain the following formula 28-3:

V1_ena4=(P4_ena/(K14*Kem2))/((m1+m0)*g-m3*g), (Equation 28-3-1);

V1_ena5=(P5_ena/Kem2)/((m1+m0)*g-m3*g), (Formula 28-3-2);

According to the safety limit threshold of the power generation feedback power and/or the energy consumption braking power, the permissible value of the downward speed when the motor brakes down is calculated. Referring to the above formula 5-4, the following formula 28-4 can be obtained:

V2_ena4=(P4_ena/(K14*Kem2))/(m3*g-(m1+m0)*g), (Equation 28-4-1);

V2_ena5=(P5_ena/Kem2)/(m3*g-(m1+m0)*g), (Equation 28-4-2);

The above formulas 28-1, 28-2, 28-3 (subdivided into 28-3-1, 28-3-2), 28-4 (subdivided into 28-4-1, 28-4-1 The permissible value of the calculated (various energy flows to the operating conditions) can be understood as the permissible value of the safely approved speed; obviously, the above calculation formula indicates that the permissible value is applicable to the current carrying quality. Value; when the carrying mass value is different, the permitted value of the speed will be different;

Obviously, from the above formulas 28-1, 28-2, 28-3 (subdivided into 28-3-1, 28-3-2), 28-4 (subdivided into 28-4-1, 28 -4-1) It can be seen that: (Kem1, Po_ena, P4_ena, P5_ena, K14, Kem2, m3, g, m0), all parameters in the brackets can be preset by the system; and only the goods carried by the elevator The mass m1 is varied; it is also possible to preset the correspondence between the mass of the carried item of the elevator m1 and the mechanical operating parameters including the upstream speed or the descending speed to control the operation of the elevator.

And the formulas 28-1, 28-2, 28-3-1, 28-3-2, 28-4-1, 28-4-1 need to know the running direction of the elevator, and the running direction is divided into uplink and downlink. Direction; formulas 28-1, 28-2 are completely different for the calculation of quality related parameters (m1, m3, m0); if the running direction of the elevator is not distinguished, the running speed of the elevator is only known according to the mass m1 of the carried item. It is wrong; if the running speed is used to control the elevator operation, it will lead to serious safety accidents of the elevator;

Therefore, it is necessary to know the mass of the carried item of the elevator and the running direction of the elevator, in order to calculate the speed, acceleration and the like of the elevator in the running direction; (selecting the mechanical operation based on parameters including at least the quality of the carried item of the elevator) Calculating the joint operation value of the mechanical operating parameter based on the parameter of the parameter, or based on a parameter including at least the quality of the carried item of the elevator.) In the technical solution in parentheses above, if the mechanical operating parameter is speed, the speed must be determined. For the uplink speed, or the downlink speed;

That is, in the technical solution in the above parentheses, if the mechanical operating parameter is speed, then: the selection scheme or the calculation scheme must be associated with the running direction; otherwise, the elevator may cause a serious safety accident.

(1.3)

The 28A-2 implementation is as follows:

When the mechanical operating parameter is any one of the acceleration at the time of accelerating the ascending, the acceleration at the deceleration, the acceleration at the time of the acceleration, and the acceleration at the deceleration, the detailed scheme 28A-2-1 of the scheme 28A-2 is preferred. 28A-2-2, 28A-2-3 are explained as follows:

28A-2-1. Calculate the allowable value of acceleration acceleration during acceleration and/or acceleration at deceleration according to the total mass m2 of the elevator car, that is, (m1+m0) and the allowable value of the integrated tension of the wire rope; when the elevator is accelerating upward , or when the elevator is decelerating downward, the maximum impact force of the wire rope will appear on the elevator car side; referring to the above formula 1-3, the following formula 28-5 can be obtained:

|aj1_ena|=|aj4_ena|=F1_ena/(m1+m0)-g, (Equation 28-5);

28A-2-2. Calculate the absolute value of the allowable value of the acceleration at the time of deceleration and/or the acceleration at the time of acceleration according to the weight value of the weight m3 and the integrated tension of the wire rope F1_ena; when the elevator is accelerating downward, or when the elevator is decelerating When going up, the maximum impact force on the wire rope will appear on the counterweight side (instead of the car side); refer to Equation 28-5 above to obtain the following formula 28-6:

|aj2_ena|=|aj3_ena|=F1_ena/m3-g, (Equation 28-6);

28A-2-3. The above 28A-2-1, 28A-2-2 scheme calculates the absolute value of the allowable value of the acceleration according to the allowable value F1_ena of the integrated tensile force of the wire rope, and the allowable value of the integrated tension of the wire rope F1_ena is usually based on the wire rope The breaking stress is further divided by a predetermined safety factor. The breaking stress can be obtained from the relevant mechanical manual of the wire rope. The safety factor can usually be set to about 12; usually the default wire rope is the weakest of the elevator. In the link, of course, the absolute value of the allowable value of the acceleration can be set by the shear stress safety value of the mechanical rotating member (such as the traction sheave, the transmission gear, and the rotor shaft of the motor) (by referring to Equation 3-3, 3- in Embodiment 3) 4, 3-5, 3-6), it is also possible to set the absolute value of the allowable value of the acceleration according to the safety value of the electromagnetic torque or the safety value of the current or the safety value of the instantaneous electrical power (by referring to the formula 4 in the foregoing embodiment 4) 5 to 4-12); the system can perform safety accounting, confirm the allowable value of the comprehensive tension of the wire rope, the safety value of the shear stress of the mechanical rotating part, the safety value of the electromagnetic torque or the safety value of the current or the safety value of the instantaneous electric power. The weakest parameter in the middle, determining the absolute value of the allowable value of the acceleration based on the weakest parameter.

Because even in the same running direction, the acceleration may have positive and negative points; the permissible values of (acceleration under various conditions) obtained by the above 28A-2-1, 28A-2-2, 28A-2-3 scheme can be understood as The absolute value of the approved value of the safety approved acceleration; obviously, the above calculation formula indicates that the permissible value is applicable to the current carrying mass value; when the carrying mass value is different, the absolute value of the permissible value of the acceleration will be different;

After the above calculation, it is obvious that when the elevator is accelerating upward, or when the elevator is decelerating downward, the maximum impact force of the wire rope will appear on the elevator car side; the smaller the value of the mass of the carried item m1, the safer. The larger the absolute value of the approved acceleration value; the larger the value of the carried item mass m1, the smaller the absolute value of the approved value of the safety approved acceleration;

When the elevator is accelerating down, or when the elevator is decelerating upward, the maximum impact force on the rope will appear on the counterweight side (instead of the car side); then the absolute value of the approved value of the safety approved acceleration and the carrying item The mass m1 is irrelevant and is related to the counterweight mass m3.

The core content of this control method (2):

(II.1)

Analyze how to control the elevator operation with the command preset value and the running upper limit threshold; the details are as follows:

Each action of the elevator lifting operation will be issued by the control system with a target parameter (the acceleration of the elevator running speed and the descending speed in the mechanical operating parameters and the acceleration in each speed change direction) (that is, the command preset value), and then An actuator such as an elevator's powertrain drives the elevator to operate at a target value (ie, a preset value);

(II.2), instructions for controlling elevator operation with preset values of instructions:

The preset value of the command is used to actively control the speed and/or acceleration of the elevator, that is, the target value of the mechanical running parameters (elevator up speed and down speed and acceleration in each speed change direction) for actively controlling the operation of the elevator, for direct use Controlling the operation of the elevator; the control mode is an active control mode; as described above, because the preset value of the command is based on at least the carrying quality of the elevator (current actual value) and the source dynamic parameter of the elevator The parameters (safety limit threshold) are calculated, so this method can make the elevator's upward speed and/or down speed and/or acceleration in each speed direction run at the maximum value, which can improve the elevator operation efficiency and also guarantee the elevator operation efficiency. Elevator operation is safe;

(II.3), instructions for controlling the operation of the elevator with the operating upper limit threshold:

The upper limit threshold of operation refers to the upper limit threshold of the acceleration of the elevator in the running speed, the descending speed and the acceleration direction; the upper limit threshold is used to control the elevator operation, which is an inactive but beneficial safety control. The control method includes the following scheme: when the upward speed/down speed of the elevator (the current value or the target value) is not greater than the running upper threshold of the running direction, The original running action of the elevator is not limited; when the upward speed/down speed of the elevator (the current value or the target value) is greater than the running upper limit threshold in the running direction, the speed limit, overspeed alarm, or shutdown protection processing is performed; The speed limit refers to limiting the current speed or the down speed (the current value or the target value) to a value not greater than the running upper threshold;

When the absolute value of the acceleration (current value or target value) of the elevator is not greater than the running upper limit threshold of the acceleration in the speed change direction, the original running action of the elevator is not limited; when the acceleration of the elevator (the current value or target) When the absolute value of the value is greater than the running upper limit threshold of the acceleration in the speed change direction, the acceleration limit, or the over limit alarm, or the stop protection process is performed; the acceleration limit refers to the acceleration in the speed change direction The absolute value of the current or target value is limited to a value not greater than the upper threshold of the operation;

The specific speed limit measures can be referred to the existing control technology, such as reducing the current target value of the speed or acceleration or the preset value of the command (such as lowering the set frequency of the inverter) to decelerate the motor, etc.; specific acceleration limit The measures can be referred to the existing control technology, such as reducing the current target value of the speed or the rate of change of the preset value of the command (such as reducing the rate of change of the set frequency of the frequency converter, reducing the slope of the speed change curve, etc.) The motor performs acceleration limiting and the like.

When the motor drive of the elevator has direct acceleration control function, the acceleration can be directly controlled to control the elevator operation; when the motor driver does not have the direct acceleration control function, the acceleration can be controlled indirectly by controlling the acceleration/deceleration running time; The current frequency (that is, the current speed) is known, and the target frequency (ie, the target speed) is known. The difference between the target frequency and the current frequency (that is, the difference in speed) is divided by the value of the acceleration to convert the ideal. Acceleration and deceleration running time.

(II.4),

The inventive 28A-1 and/or 28A-2 scheme calculates the mechanical operating parameters for controlling the operation of the elevator based on the quality of the goods carried by the elevator (preferably the current actual value) and the source dynamic parameters (preferably the safety limit threshold). The safety value, the safety value of the mechanical operation parameter includes at least one of the permissible value of the safety approved speed and the absolute value of the safety approved acceleration value, and the elevator speed can be the fastest/efficiency while ensuring safety. The highest, belonging to the highly intelligent program of elevator motion control;

When the source dynamic parameter is the current measured value and the carrying quality is the current joint operation value or the measured value, the calculated joint operation value of the mechanical operating parameter is also the current value; according to the invention, according to the mechanical operating parameter The joint operation value or the corresponding value of the grade controls the elevator operation" may further include the following scheme: detecting whether the current value of the mechanical operation parameter obtained through the joint calculation exceeds a preset safety limit threshold, and if so, correlating Alarm, or speed limit processing;

Referring to the above calculation method, the rated value/manual preset value of the source dynamic parameter can also be selected to be calculated in conjunction with the current actual value of the carrying quality, and the corresponding value of the mechanical operating parameter can be understood as: the load in the elevator is The current speed or acceleration rating/manual preset value when carrying the mass value; the upper limit threshold may also be operated as the command preset value according to the speed or acceleration rating/manual preset value to control the elevator operation, The control method can refer to the above scheme.

The core content of this control method (3):

The calculation or acquisition of the safety value of the mechanical operation parameter for controlling the operation of the elevator, in addition to the above-mentioned basic embodiment 28A, there are various methods such as the look-up embodiment 28B, the most simplified embodiment 28C, and the 28D implementation;

28B embodiment is described as follows: the value of the mechanical operating parameter of the elevator (joint operation value), in addition to the preferred calculation scheme of 28A above, can also perform low performance according to the carrying quality and source dynamic parameters of the elevator, but is simple Calculating; if preset, the associated form of the elevator's carrying quality, source dynamic parameters, and mechanical operating parameters, the associated table is the second associated table; when the known carrying mass and source dynamic parameters are input, the checklist is derived. Running the value of the parameter (joint operation value); controlling the elevator operation according to the value of the mechanical operation parameter;

The description of the 28C implementation is as follows: preset an association table of the carrying quality of the elevator and the mechanical operating parameters, the associated table is the first associated table; when the known carrying quality is input, the look-up table obtains the mechanical operating parameters (upstream speed, a value of a downlink speed, an acceleration at an acceleration uplink, and an acceleration at a deceleration downlink (joint calculation value); controlling the elevator operation according to a value of the mechanical operation parameter;

28D Embodiment Description: The above 28A, 28B, and 28C are calculations of values (joint operation values) of mechanical operation parameters of the elevator inside the control system; and values of mechanical operation parameters by external and other systems are also allowed (joint operation) The calculation of the value) only needs to be calculated by the calculation method described in 28A, 28B, and 28C; the value of the mechanical operation parameter calculated by the external and other systems (joint operation value) is read; The value of the parameter controls the operation of the elevator;

In the present invention, in addition to calculation using a formula/model, the look-up table is also a calculation method, a table calculation; the above formula 28-1, formula 28-2, formula 28-3-1, formula 28-3-2 Formula 28-4-1, formula 28-4-1, formula 28-5, formula 28-6, second association table, any formula in the first association table, and a table may be referred to as at least one of The mapping relationship between the parameters of the elevator's carrying quality and the mechanical operating parameters of the elevator;

Determining the value of the value of the mechanical operating parameter according to the carrying quality, usually at a certain time, such as when the elevator is closed, before starting the lifting operation; of course, the value action can also be performed during the lifting process. The value is chosen by the user.

Of course, in any of the above 28A, 28B, 28C, and 28D, "controlling the elevator operation according to the value of the mechanical operation parameter", the controlling the elevator operation refers to controlling the elevator to meet the safety specification operation;

The core content of this control method (4):

The above content has solved the source of the safety value of the mechanical operation parameter for controlling the operation of the elevator, and analyzed how to control the elevator operation according to the preset value of the command and the upper limit threshold of the operation. The following content will focus on how to perform the binning and how to perform the binning according to the grade. Or discrete values control elevator operation, the specific content is as follows:

The core purpose of the control scheme is to adjust the elevator uplink speed and downlink speed according to the carrier quality (current actual value) and the allowable value of the electric power; when the mechanical operating parameter is the uplink speed or the downlink speed, when the "at least two" When it is only two, it can be simply understood as a high speed value and a low speed value (high speed value > low speed value); when the "at least two" is only two, it can also be understood as two different speeds of the speed. One high speed gear and one low speed gear have a corresponding value for each grade; (speed of high speed gear > speed of low speed gear);

The special agreement of the present invention is as follows: "at least two" does not include the case where the mechanical operating parameter is zero or the difference between the mechanical operating parameter value and zero is less than a predetermined value; the main purpose of the agreement is for the technical personnel in the industry. Easy to understand and operate, at least two Excluding zero speed.

When the elevator is up or ready to go up, a judgment threshold is set, that is, a third preset value. If the value of the carrier quality is greater than the third preset value, an instruction preset value of the uplink speed is output; for example, the carrier quality If the value is less than the third preset value, another different size command preset value of the uplink speed is output; for example, when the absolute value of the difference between the value of the carried item quality and the balance value is less than the third preset value, Using the high speed value as the command preset value of the up speed or the running upper limit threshold, or controlling the elevator to operate at the high speed; when the absolute value of the difference between the value of the carried item mass and the balance value is greater than or equal to the third preset Value, the low speed value is used as the command preset value of the up speed or the upper limit threshold, or the elevator is controlled to run at the low speed;

When the elevator is descending or preparing to go down, when the "at least two" is three, the three speeds can be simply understood as "high speed value, medium speed value, low speed value", the high speed value is greater than the medium speed value, and the medium speed value is greater than Low speed value; can also be understood as three different speeds of the speed, one high speed, one medium speed, one low speed, the high speed speed is greater than the middle speed speed, the middle speed speed is greater than the low speed speed; Two judgment thresholds (ie, the fourth preset value and the fifth preset value) are set, and the absolute values of the difference between the value of the carried item mass and the balance value are simply divided into three types: large, medium, and small. Interval; for example, the absolute value of the difference between the balance value and 0 can be set as the maximum difference, or the absolute value of the difference between the rated load and the balance value is set as the maximum difference; (0<fourth preset value< The fifth preset value <maximum difference value, the "small" area is the interval from 0 to the fourth preset value, the "middle" area is the interval from the fourth preset value to the fourth preset value, and the "large" area is The interval from the fifth preset value to the maximum difference; when the absolute value of the difference between the value of the carried item quality and the balance value is "large" When the zone is used, the low speed value is used as the command preset value of the up speed or the upper limit threshold of the operation, or the elevator is controlled to run at the low gear; when the absolute value of the difference between the value of the carried item mass and the balance value is in the middle "In the zone, the medium speed value is used as the command preset value of the up speed or the upper limit threshold value, or the elevator is controlled to operate in the intermediate speed; when the absolute value of the difference between the value of the carried item mass and the balance value When in the "small" zone, the high speed value is used as the command preset value of the up speed or the upper limit threshold value, or the elevator is controlled to operate at the high speed gear;

Certainly, the foregoing partitioning according to the third preset value, the fourth preset value, and the fifth preset value is merely an example, and is not limited; the user may adjust the preset values and self-zoning by referring to the manner;

Therefore, when the "at least two" are a finite number (such as 4, 5, 6, 8, etc.), the value of the mechanical operating parameter is substantially a plurality of discrete values, and the elevator is based on the plurality of discrete values. Divided into multiple files for control. As for the speed of the high speed/high speed, the speed of the medium speed/intermediate speed, and the speed of the low speed/low speed, the specific value of the value can be set according to the type test, a limited number of experiments, and a manual test. The scheme is determined by the scheme, and can also be set by referring to any of the above mapping relationships (formulas or tables). All preset values in this paper can be determined according to the type test setting, limited number of experiments, manual trial and error methods.

According to the 28A, 28B, 28C, and 28D schemes, more grades/discrete values, even stepless speed regulation are allowed, so that the elevator operating efficiency can be improved when the elevator is in any load from no load to full load;

The core content of this control method (5):

Analysis of the relationship between the safety values of mechanical operating parameters (especially the permissible values of speed) for various load conditions (eg, no-load, light load, load balancing, heavy-load, full load);

(V.1)

Obviously, when the current value of the mass of the carried item is zero (m1=0), it is empty; when the current value of the mass of the carried item is equal to the rated load m1_ena (m1=m1_ena) of the elevator, it is full load; For a counterweight elevator, and the counterweight mass m3 is usually greater than the no-load car mass m0;

The calculations calculated by the above formulas 28-1, 28-2, 28-3-1, 28-3-2, 28-4-1, 28-4-2 show that when the mass value of the carried item m1 and the quality of the empty car The smaller the difference between the sum of the value m0 and the counterweight mass value m3, the larger the permissible value of the safely approved speed; theoretically, when the sum of the carried item quality value m1 and the no-load car mass value m0 is equal to When the weight is m3 (ie, m1+m0=m3), that is, the mass balance between the left and right sides of the traction sheave, the allowable value of the speed is the largest at this time, and the value of the mass m1 of the carried item in this case is the balance value. At this time, the load condition of the elevator is called load balance; the balance value is the absolute value of the difference between the weight mass value m3 and the no-load car mass value m0; since the balance value is usually half of the rated load weight m1_ena of the elevator, Therefore, load balancing can also be called half load;

For ease of understanding, the invention provides that when the quality value of the carried item is greater than zero and less than the first preset value (0<m1<first preset value), it is light load; when the quality value of the carried item is greater than or equal to the second preset value And is less than the rated load weight m1_ena of the elevator (the second preset value ≤ m1 < m1_ena) is a heavy load;

(the first preset value ≤ the second preset value); for example, the first preset value may take 0.5 times the balance value, and the second preset value may take 1.5 times the balance value; of course, the value is the first preset value, The second preset value can be adjusted by the user; but in general, for the convenience of understanding, it is better to comply with the following mathematical rule: (0 <first preset value <balance value), (balance value < second preset value <m1_ena )

The smaller the allowable value of the upstream speed and/or the downstream speed when the elevator approaches the full load;

When the elevator is fully loaded up, it consumes more electric power, and the allowable value of the upward speed is lower than that during load balancing; and this value is subject to the power safety value Po_ena of the motor (usually equal to the rated power of the motor) in the electric state;

When the elevator is fully loaded down, the allowable value of the downstream speed is lower than that of the load balance; and this value is subject to the absorption power of the electric power system to the braking power, and is independent of the power safety value Po_ena of the motor (usually equal to the rated power of the motor). ;

Different from conventional bias (such as higher and faster down speed when the elevator is lightly loaded down to allow load balancing): when the elevator is lightly loaded down (that is, the value of the carried item mass m1 approaches zero), The electric power consumption is high, and the allowable value of the downward speed is lower than that at the time of load balancing; and the value is subject to the power safety value Po_ena of the motor (usually equal to the rated power of the motor) in the electric state;

The difference from the conventional prejudice (such as the higher and faster uplink speed when the elevator is lightly loaded and the load is allowed to balance the load) is that when the elevator is lightly loaded, the allowable value of the upward speed is lower than when the load is balanced; The value is subject to the safety value P4_ena or P5_ena of the braking power, independent of the motor's power safety value Po_ena (usually equal to the rated power of the motor).

(V.2)

In general, unlike the conventional prejudice, it is not allowed to run fast when the elevator is lightly loaded; the upward and downward speeds of the elevator that control the elevator operation and the target value of the acceleration in each speed change direction, the upper limit threshold of operation, each grade Corresponding values, all need to go through The in-depth safety calculation can be known; the "controlling the elevator operation" in the present invention means "controlling the elevator to control the elevator to comply with safety specifications";

The compliance with the safety specification is at least one of the following safety conditions 1, safety conditions 2, and safety conditions 3;

Safety condition 1: The process as shown in embodiment 28A, the joint operation value of the mechanical operation parameter for controlling the operation of the elevator or the corresponding value of the gear (that is, the command preset value or the operation upper limit threshold) is a mechanical operation parameter. a safety value, the safety value of the mechanical operating parameter being calculated based on a parameter comprising at least a carrying mass (preferably a current actual value) and a source dynamic parameter (preferably a safety limit threshold) (as shown in embodiment 28A); It can be understood that it is safe to control the elevator operation with the safety value of the mechanical operating parameter;

Safety condition 2: According to the 28B, 28C, 28D scheme, the joint operation value of the mechanical operation parameter for controlling the elevator operation or the corresponding value of the grade (that is, the instruction preset value) is obtained by looking up the table or from the external and other systems. Or run the upper threshold) and verify from the result that the value is not greater than the safe value of the mechanical operating parameters;

The safety value of the mechanical operating parameter is calculated based on parameters including at least the carrying mass (preferably the current actual value) and the source dynamic parameter (preferably the safety limit threshold) (as shown in embodiment 28A); understandable It is safe to control the elevator operation with the value of the mechanical operating parameter;

Safety condition 3: the joint operation value of the mechanical operation parameter for controlling the operation of the elevator or the corresponding value of the gear (that is, the command preset value or the operation upper limit threshold) and the source corresponding to the carrying quality (current actual value) The value of the dynamic parameter is not greater than the safety limit threshold of the source dynamic parameter; in the specific implementation manner, the value of the corresponding source dynamic parameter may be obtained by the above formulas 28-1, 28-2, 28-3-1, 28-3-2 The deformation formula of 28-4-1, 28-4-2 is calculated.

(V.3)

According to the analysis of the above content, the elevator operation is controlled according to the joint operation value of the mechanical operation parameter or the corresponding value of the grade, and when the value of the carried item quality is greater than zero, that is, non-no-load operation, the following adjustment may be followed. At least one of speed schemes 1, 2, 3, 4, 5, 6, and 7;

Speed regulation scheme 1: The allowable value of the upward speed of the elevator at light load or heavy load should be less than the allowable value of the upward speed at the time of load balancing;

Speed regulation scheme 2: The preset value of the upward speed of the elevator at light load or heavy load should be less than the preset value of the upward speed of the load balance time;

Speed regulation scheme 3: The upper limit threshold of the upward speed at light load or heavy load should be less than the upper limit threshold of the upward speed at load balance;

Speed regulation scheme 4: The allowable value of the descending speed of the elevator at light load or heavy load shall be less than the allowable value of the descending speed of the elevator at the time of load balancing;

Speed regulation scheme 5: The preset value of the downward speed command at light load or heavy load should be less than the preset value of the downward speed at load balancing;

Speed regulation scheme 6: The upper limit operating threshold of the down speed at light load or heavy load should be less than the upper limit threshold of the down speed at load balancing;

The core content of this control method (6): Description of the optimization scheme of the control method:

The implementation of the 35A1 solution of the present invention: the identification of the presence or absence of personnel in the car can be identified by various means such as optical, infrared, video sensor, weighing, etc., and preferably combined by two or more methods to avoid Misjudgment; the presence or absence of personnel in the car includes two conditions in the car, no one in the car, such as when the weighing result is zero and the infrared detection is unknown, the current car can be identified;

From the theoretical analysis point of view, the above formula 28-1, formula 28-2, formula 28-3-1, formula 28-3-2, formula 28-4-1, formula 28-4-2 indicate that when the source dynamic parameters When the safety limit threshold is constant, the permitted value of the safety approved speed when the car is unmanned (that is, the mass of the carried item is 0) is smaller than that at the time of light load;

However, because the safety factor requirement is reduced when there is no one in the car, the safety limit threshold of the source power parameter when there is no one in the car can be higher than the safety limit threshold of the time source power parameter in the car; therefore, The allowable speed value (command preset value/operating upper limit threshold) when no one is in the car can be set to be larger than at light load, so that the elevator can be at a higher speed or higher when no one is in the car. Acceleration operation can greatly improve the operating efficiency of the elevator;

The higher operating efficiency of the present invention may include any of the following 35A1-1, 35A1-2, and 35A1-3:

35A1-1, increasing a value of the source dynamic parameter in the control method or adjusting other joint operation values or grades that may affect the mechanical operating parameter of the elevator, so as to control the mechanical operating parameter of the elevator operation The command preset value and/or the running upper limit threshold are increased indirectly;

35A1-2, directly increasing the command preset value and/or the running upper limit threshold of the mechanical operating parameter; the mechanical operating parameter includes any one of an upward speed, a descending speed, an acceleration when accelerating the ascending, and an acceleration when decelerating down or Multiple parameters.

The beneficial effect of the 35A1 solution of the present invention is that the elevator will often be in an unmanned state in the car. From the common sense, the safety factor can be correspondingly reduced when there is no one in the elevator; when there is someone in the elevator car, the safety factor of the elevator needs to be maintained. To ensure safety; through this 34A1 solution, the elevator can be operated at a higher speed or higher acceleration when no one is in the car, which can greatly improve the operating efficiency of the elevator.

The core content of this control method (7):

The beneficial effects of the control method and system for elevator operating efficiency provided by the invention are as follows:

In the prior art of the current elevator, no matter whether a person or a person is riding, regardless of the load and weight, the operation is performed at the same speed, which is inefficient, unscientific, and is not conducive to energy conservation and environmental protection;

According to the analysis of the content of this application, if you want to control the elevator operation safely and efficiently, you need to overcome a variety of technical problems: you need to understand the unique impact of heavy mass m3 on elevator operation; you need to distinguish between zero speed operation and shifting. Various conditions such as operation, non-zero uniform speed operation, etc., need to distinguish various electric energy flow conditions such as electric up, motor brake up, electric down, motor brake down; etc.; need elevator quality, source dynamic parameters, system operating parameters The parameters are then combined with the energy conservation law, Newton's law, unique elevator operating characteristics and other factors to calculate the energy balance of the elevator operation, especially the mechanical operation characteristics of the elevator and the electrical dynamic parameters as the source dynamic parameters to achieve deep understanding. Hierarchical cross-field electromechanical combination of elevator operation energy balance calculation; in the complex elevator operation energy balance calculation, it also needs to be related to the elevator running direction, motor working condition correlation 1, motor working condition correlation 2, motor working condition correlation 3, motor working condition correlation 4, speed change correlation 1, speed change association 2, etc. Correlation calculation; need to overcome many industry biases, need to carry out a lot of creative analysis and research, it is possible to obtain a mechanical operating parameter that meets safety regulations (upward speed, down speed, acceleration when accelerating up, acceleration at deceleration down or Multiple parameters) safe and efficient control of elevator operation;

The inertial thinking in the industry may think that the elevator speed is not suitable for adjustment. It may be considered that the high speed will damage the safety, and the fast running speed may easily lead to the steel wire rope breaking, which are all industry biases; industry bias may consider the elevator ascending speed, The downstream speed can be divided, and it is not necessary to distinguish between the electric motor state and the motor braking state; even if the motor braking state is distinguished, it may be considered that the higher the braking state is, the higher the power generation is, the better;

Due to the existence of many technical problems and industry prejudice, the current industry has formed an overall industry bias as follows: fixed-type elevators are safe only when operating at a fixed speed; if different operations are set according to different delivery qualities Speed is not safe;

The control method of the elevator provided by the present invention has the core purpose as the effect: overcomes many technical problems and overcomes industrial prejudice; and analyzes the formulas of formulas 28-1, 2, 3, and 4 provided by the present invention, and is accurate Distinguish the energy flow of the elevator to the working conditions (such as Elevator up, down, electric state, motor braking state, etc.) According to the current carrying item mass m1, the safe value of the running speed can be calculated relatively accurately; when the elevator goes up/down, the basic calculation structure is different, the electric state electric power The safety limit threshold is usually the minimum rated power value of the power supply, the motor drive, and the motor. The safety limit threshold of the electric power during the motor braking state is usually between the power supply, the motor drive, the motor, and the brake system. The minimum allowable value of the power generation feedback braking power and/or the energy consumption braking power. When the status is different, the safety limit threshold of each electric power may have a large difference; if the energy flow of the elevator is not distinguished from the working condition, the speed adjustment is blind. Not only does it fail to adjust the speed, but the elevator is not safe. Even in the motor braking state, if the speed is too high, the braking power will exceed the absorption capacity of the electric power system, resulting in an increase in the bus voltage inside the inverter. It is easy to cause a fault/explosion.

In the field of elevators, there is a lack of open literature on damage studies of elevator machinery; according to Newton's 2 law (F=m*a) and the formula 1-2 provided by the present invention (F1_cal=(m1+m0)*(g+aj)) Analysis, the damage of the mechanical device is not directly related to the speed/power (it does not cause the wire rope to break when the speed is fast/powerful); the direct cause of the damage of the mechanical device is that the acceleration is too large at a certain load, which will lead to the mechanical system. The stress is greater than the safety threshold (such as the wire rope pulling force is greater than the breaking stress and breaking, such as the instantaneous torque overrun / shear stress overrun causes the drive shaft to break, the gear burst, etc.); when accelerating the upward movement, or when decelerating down, According to formula 28-5, according to the current m1 value of the elevator's current carrying item mass, a reasonable acceleration can be calculated to avoid the over-limit (or even break) of the comprehensive pulling force F1 of the wire rope; when accelerating down, or when decelerating upward, it must be according to formula 28- 6 According to the counterweight mass m3 value of the elevator (not the m1 value), a reasonable acceleration can be calculated to avoid the over-limit (or even break) of the comprehensive tension F1 of the wire rope;

By using the control method and system for elevator operating efficiency provided by the invention, the safe running speed and/or acceleration of the elevator can be accurately set, which plays an important role in improving the operating efficiency of the elevator and improving the safety performance of the elevator operation; It has become the basic equipment in modern life. In the same building, the elevators of the same number and the same type, if using this control method and system, can control the elevator operation efficiently on the basis of ensuring safety, that is, let the elevator run faster. More reasonable; shorten the waiting time of passengers, take the elevator time, reduce the passenger's use time and use cost; if the same amount of transportation is guaranteed, the safety of the elevator, the number of uses, the frequency of use can be reduced, and the elevator can be greatly reduced. The consumption of space resources, equipment funds and electricity in buildings is conducive to environmental protection, energy conservation and consumption reduction.

Technical question five:

The fifth technical problem to be solved by the present invention is to provide a monitoring method for an elevator operating parameter overrun to improve safety when the elevator is running;

39. The present invention further provides a monitoring method (#3) for an elevator operating parameter overrun, comprising the steps of: acquiring a joint operation value of the source power parameter of the elevator, and determining whether the joint operation value exceeds the source dynamic parameter. System preset value or safety limit threshold; the joint operation value is calculated based on the elevator running energy balance; the elevator running energy balance is calculated as a formula according to the formula describing the balance of the power of the elevator and the related force or its deformation The calculations performed; the associated forces include the gravitational force corresponding to the total mass of the elevator car and/or the gravitational force corresponding to the counterweight mass.

In the monitoring method (#3), it is used to judge whether the source power parameter of the elevator belongs to the limit; the preset value of the system can be selected according to the actual demand, but generally satisfies: 0<system preset value≤source power parameter Safety limit threshold.

For example, the source power parameter is the pulling force of the wire rope of the elevator, and the preset value of the system may be the normal value (ie, the rated value or the calibration value) of the pulling force of the wire rope, which is usually passed the type test, or the manufacturer, or the professional. The detection mechanism is given; the system preset value can also be used as the ideal value required by the user on site and confirmed on site; the system preset value can also be the safety limit threshold value × 80% value; once the joint operation value of the tensile force of the wire rope exceeds the safety limit threshold value, Then the source power parameters are exceeded.

If the joint operation value of the measurement object is within a certain range defined by the reference data, the elevator condition is set to a certain level; if the measurement object is When the joint operation value is outside a certain range defined by the reference data, the elevator condition is set to another level; one of the preferred objects of the measurement object is the efficiency coefficient, especially the efficiency of the power system as a whole or the power to be monitored. Efficiency of the transmission component; for example, the range 1 of the reference data is a value range greater than or equal to 95%, the range 2 of the reference data is a value range less than 95% and greater than 90%, and the range 3 of the reference data is less than or equal to 90% The value range, when the efficiency coefficient is within the range 1 of the reference data, the elevator elevator condition is set to A or 1 or superior or upper level; when the efficiency coefficient is in reference data When the range is within 2, the elevator elevator condition is set to B or 2 or normal or medium level; when the efficiency coefficient is within the range 3 of the reference data, the elevator elevator condition is set to C or 3 or worse. Or the lower level; the second preferred object of the measurement object is the rolling frictional resistance coefficient μ1; for example, the range 1 of the reference data is a value range of less than or equal to 0.01, and the range 2 of the reference data is a value range of less than 0.015 and greater than 0.01, with reference to The range 3 of the data is a value range greater than or equal to 0.015; when μ1 is within the range 1 of the reference data, the elevator elevator condition is set to A or 1 or superior or upper level; when μ1 is in the range 2 of the reference data When the elevator elevator condition is set to B or 2 or normal or medium level; when μ1 is within the range 3 of the reference data, the elevator elevator condition is set to C or 3 or inferior or lower level;

For a typical implementation of the above 30A2, 30A4 scheme, see Example 1, Process 2 of Process Method 2 below:

Example 1 of Processing Method 2:

When the measured object is the total mass m2 of the elevator car, the joint operation value m2__cal of the total mass m2 of the elevator car of the same time period and the actual value m2_org as the reference data are acquired, and the range 1 of the reference data is a value range of less than or equal to 100 KG. , the range 2 of the reference data is a value range of less than 200 KG and greater than 100 KG, and the range 3 of the reference data is a value range greater than or equal to 200 KG; When the absolute value (|m2__cal-m2_org|) of the difference between the joint operation value (m2__cal) of the measurement object and the reference data (m2_org) of the measurement object is within the reference data range 1, the elevator elevator condition is set to A or 1 or superior or upper rank; when the absolute value of the difference between the joint operation value (m2__cal) of the measurement object and the reference data (m2_org) of the measurement object (|m2__cal-m2_org|) is within the reference data range 2 When the elevator elevator condition is set to B or 2 or the normal cargo grade; the absolute value of the difference between the joint operation value (m2__cal) of the measurement object and the reference data (m2_org) of the measurement object (|m2__cal- M2_org|) When the reference data range 3 is within, the elevator elevator condition is set to C or 3 or inferior or lower level;

Example 2 of the processing method 2: When the measured object is the motor torque T in the source dynamic parameter, the joint operation value T__cal of the motor torque T in the same time period and the actual value T_org as the reference data acquired by the actual measurement method are acquired, The range 1 of the reference data is a value range smaller than or equal to 20N.M, the range 2 of the reference data is a value range smaller than 50N.M and larger than 20N.M, and the range 3 of the reference data is a value range greater than or equal to 50N.M. When the absolute value (|T__cal-T_org|) of the difference between the joint operation value (T__cal) of the measurement object and the reference data (T_org) of the measurement object is within the reference data range 1, the elevator elevator condition is set Set to A or 1 or superior or upper rank; the absolute value (|T__cal-T_org|) of the difference between the joint operation value (T__cal) of the measurement object and the reference data (T_org) of the measurement object is in the reference data range 2 When the elevator elevator condition is set to B or 2 or normal or medium level; the absolute value of the difference between the joint operation value (T__cal) of the measurement object and the reference data (T_org) of the measurement object (| T__cal-T_org|) When the reference data range is within 3, the elevator status is 3 or as C or lower or inferior level;

Similarly, referring to examples 1, 2 of the above processing method 2, parameters to be measured and/or measurable parameters and/or elevator mass and/or source dynamic parameters and/or mechanical operating parameters and/or mass changes may also be used. Any other parameter in the quality of the type of article is used as a measurement object (for example, a longitudinal velocity and a longitudinal acceleration are used as measurement targets), and the situation information of the elevator is set;

When the measurement object is any one of the unmeasured parameter and/or the preset parameter and/or the system intrinsic parameter, the calibration value of the measurement object is preferably used as the reference data, and the examples 1 and 2 of the processing method 2 are referred to. Setting status information of the elevator elevator;

In general, the absolute value of the difference between the joint operation value of the measurement object and the reference data of the measurement object tends to be large, indicating that the elevator condition tends to be bad;

In the above method, the reference data is set to a certain range; there are more feasible ways, for example, the reference data is set to a base number 3, which can be used to identify the status information of the elevator, and select the status information that can be used to identify the elevator. The calculation rule identifies the status information of the elevator; referring to the example 1 of the processing method 2 above, the absolute value of the difference between the joint operation value of the measurement object (for example, m2__cal) and the reference data of the measurement object (for example, m2_org) (for example) |m2__cal-m2_org|) Divide by the base 3 (for example, set to 100KG), round up, and directly use the result as the status information of the elevator; directly obtain the same level information of ABC or 123.

Further, that is, preferably, in the processing method (#2): taking any one of the elevator quality, the system inherent parameter, and the quality-changing item quality as the measurement object; or in the elevator operation parameter other than the longitudinal acceleration Any one of the parameters is used as the measurement object; or any one of the elevator operation parameters except the source dynamic parameter is used as the measurement object; or any one of the elevator operation parameters except the longitudinal acceleration and/or the source dynamic parameter The parameter is used as the measurement object;

Comprehensive explanation:

The invention provides a monitoring method and system (#1) for an elevator during lifting operation, an elevator load monitoring method and system (#2), an elevator control method and system, and an elevator operating parameter The over-limit monitoring method and system (#3), an elevator monitoring method and system, and some of the same technical features between the five, all of the methods for obtaining the value of the elevator operating parameter provided by the present invention and The core inventive idea of the system is related to: a scheme for acquiring the joint operation value of the measurement object of the elevator, and the joint operation value is calculated based on the energy balance calculation of the elevator operation, and the energy balance calculation of the elevator operation is associated with the running direction of the elevator;

However, the functions and points of action between the five are different;

The invention provides a monitoring method and system (#1) for elevator lifting operation, and the core idea is to compare the joint operation value of the measuring object of the elevator with the reference data; the first reference value in the reference data is required to be as close as possible The actual value of the measured object (such as the mass of the carried item); the first reference value can be much smaller than the safety limit threshold of the parameter (such as the maximum legal load of the elevator); Take the elevator (assuming 75kg per person), the normal weighing result should be 300kg, once the elevator car shows 350kg or 250kg, the safety processing mechanism can be activated immediately; to achieve the pair (including the personnel being stuck in the car and the elevator shaft) The cause of the accident is that the elevator energy transmission is abnormally monitored and early warning, so that more serious and unpredictable safety accidents (including personnel jamming, wire rope breakage, etc.) occur before the safety limit threshold of the elevator is triggered. Transmission gear bursting, motor drive bomber, elevator out of control, etc.) before monitoring and protection; although the elevator has safety clamp limit speed limit, bottom protection, electrical overcurrent, overvoltage protection and other parameters of the safety limit threshold exceeded Protection, but once the elevator triggers various limit protections, the elevator will enter an unknown, uncontrollable state; the effect of the limit threshold overrun function of each parameter is difficult to test when the elevator is in normal operation, and it is seriously biased as a safety protection sensitivity. Low, basically the limit action after the event; suppose the limit speed limit of the safety clamp can normally lock the guide rail, and suddenly the elevator is suddenly stopped at high speed. It will also seriously alarm elevator passengers, easily lead to pregnant women, elderly passengers, children and casualties; even if it is a passenger in the prime of the year, if there is an accident between the car and the well wall, the safety gear may have serious casualties before the limit speed limit is imposed. .

The monitoring method and system (#1) can usually work in real time when the elevator is running up and down;

The invention provides a method and system for monitoring elevator load (#2), the core idea is that the combined operation value of the quality of the carried goods of the elevator is compared with the safety limit threshold, for example, when the mass of the carried item is greater than 1.0 times the elevator The maximum legal load (assuming 14 people / 1050kg) is to initiate a voice alarm to remind the passengers to reduce the quality of the carrier/item; even if the actual 4 passengers take the elevator / the normal weighing result should be 300kg, but when the weighing system is called When the amount is 1000kg, the traditional elevator control system will still consider the elevator's energy transfer system to work properly.

The elevator load monitoring method and system (#2) can work intermittently at a certain time (such as when the elevator runs at zero speed), and can also monitor the work continuously/real time during elevator lifting operation.

According to the analysis, the former (the monitoring method and system (#1) of the elevator lifting operation) provided by the present invention is much higher than the latter in the elevator lifting operation (a type of elevator load monitoring) Method and system (#2)), of course, the latter can achieve weighing and overload monitoring before the elevator runs at zero speed; it can play a necessary supplementary role for the former, and still has important significance.

The invention provides a method and a system for controlling the operating efficiency of an elevator. The core idea is to set the permission value of the mechanical operating parameters of the elevator (such as the maximum speed allowed, the highest acceleration), or the mechanical operating parameters of the elevator have exceeded the permissible value. Time limit control (such as overspeed, super acceleration) for control and protection, such as speed limit, acceleration limit, alarm, shutdown, etc.; The control method and system, the core purpose is elevator efficient, energy saving control.

The present control method and system, when used for planning of target speed and/or target acceleration, may be intermittently operated after acquiring the mass of the vehicle and at some time before the high speed operation; when used for the speed threshold and/or the acceleration threshold When the limit is controlled, it can also work continuously/real time when the elevator is running up and down;

The invention provides a monitoring method and system (#3) for an elevator operating parameter overrun, and the core idea is to calculate a joint of source power parameters according to an instruction preset value of speed and/or acceleration (to be executed but not yet occurring). Whether the calculated value, prediction and judgment (such as electric power or wire rope tension) will exceed the limit, in a sense, has the effect of preventing future risks; the control method and system, the core purpose is the elevator operation safety control.

The monitoring method and system (#3) can work before the elevator runs, predict whether the source power parameters will exceed the limit according to the preset value of the speed and/or acceleration command; or can work continuously/real time during the elevator running, The source dynamic parameter overrun prediction is performed on each of the command preset values of the speed and/or acceleration to be executed.

The ideal control method of the elevator can be: selecting the safety limit valve of the electric power/power generation feedback power/or the energy consumption braking power in the electric state according to the motor operating condition (electric/motor braking state) in the elevator energy flow direction. Value, and then set the elevator running speed according to the safety limit threshold of the electrical quantity of the goods and the electrical power of the motor operating conditions (refer to the above 28A-1 scheme), set the core with safety and high speed; the setting of the running acceleration is Can refer to the above 28A-2 scheme, with strict safety as the core (ensure that the acceleration does not cause mechanical stress to exceed the limit, and does not cause broken rope, transmission shaft/gear damage);

According to the safety limit threshold of the quality of the carried goods and the power of the motor operating conditions, the operating speed of the elevator can be set to greatly improve the operating efficiency of the elevator. When the same occupant demand is met, the number of elevator installations can be reduced, thereby saving The installation cost, manufacturing cost, maintenance cost and power consumption of the idle elevator have significant energy conservation and environmental protection significance.

The jerk J of the elevator, that is, the setting parameter of the S degree of the acceleration/deceleration S curve, is related to the comfort of the human body; when the jerk J is too large, the acceleration and deceleration stress that the human body is subjected to is too large to cause discomfort or even no Safety; therefore, the jerk J can be set according to the national or related industry regulations; when the speed, acceleration and jerk J of the elevator have been set, the elevator can run on the ideal S curve to achieve efficient, safe and comfortable operation;

According to the set S curve, the system can further set the ideal deceleration distance; the S curve deceleration operation can be divided into three sections (initial deceleration phase S5, uniform deceleration phase S6, final deceleration phase S7); The acceleration value of phase S6 is 0, and the acceleration is the set safety limit threshold; the time of S5 and S7 can be obtained by dividing the acceleration permission value by the absolute value of the permissible value of the jerk; because each segment of S5, S6, S7 The speed value and time can be obtained, so the deceleration distance can be accurately known.

And all the technical solutions provided by the invention are used without weighing the sensor as much as possible, preferably for weighing, overload monitoring, speed and/or acceleration with electrical power parameters of the electric power system, in particular electromagnetic torque or torque current. Planning can improve control accuracy and reduce costs.

Because the current elevators have mature motor drives (such as inverters or integrated elevator controllers), central controllers, network transmission systems, and mature human-computer interaction interfaces (display or voice);
