In conjunction with following embodiment 1 to 6 etc., apparent known, in the present invention according to quality of elevator, driving source ginsengIn number, system operational parameters, any two kinds of parameters go to calculate another kind of parameter, and the parameter that participates in this calculating also may be furtherComprise other data, elevator operation energy balance calculate be often referred to according at least comprise quality of elevator, driving source parameter,The data of any two kinds of parameters in system operational parameters go to calculate another kind of parameter. As formula 1-1,1-4 in embodiment 1When middle measuring and calculating object is article quality m1, the parameter that participates in calculating also comprises the m0 in quality of elevator; In embodiment 4In formula 4-13, when measuring and calculating object is the frictional force fr of the revolving part in system operational parameters, also participate in the parameter of calculatingComprise the frictional force f0 of object and car in guide rail and/or elevator hoistways; In embodiment 5, in formula 5-1, calculating object isWhen elevator speed in system operational parameters, the parameter that participates in calculating also comprises the g in system operational parameters, differs hereOne enumerates, and concrete can be with reference to following each embodiment.

In the time that measuring and calculating object is quality of elevator, the join operation value of described quality of elevator is according to driving source parameter and system fortuneLine parameter calculates gained, certainly participates in the required parameter of this calculating and also may further comprise that other data are as quality of elevatorIn other parameters; Also when measuring and calculating object is while being quality of elevator, described join operation value can be according at least comprising driving sourceParameter and system operational parameters are calculated gained in interior data.

In the time that measuring and calculating object is driving source parameter, the join operation value of described driving source parameter is according to quality of elevator and systemOperational factor is calculated gained, certainly participates in the required parameter of this calculating and also may further comprise other data; Also work asWhen measuring and calculating object is driving source parameter, described join operation value can be according at least comprising that quality of elevator and system operational parameters existInterior data are calculated gained.

When measuring and calculating object is while being system operational parameters, the join operation value of described system operational parameters be according to quality of elevator andDriving source calculation of parameter gained, certainly participates in the required parameter of this calculating and also may further comprise other data, as removeThe system operational parameters of other outside measuring and calculating object; Also when measuring and calculating object is while being system operational parameters, the described fortune of combiningCalculation value can be calculated gained according to data including quality of elevator (being generally elevator gross mass) and driving source parameter at least;

The elevator operation energy balance computing formula of most typical elevator operation is as (m1+m0) * g-m3*g=(Kem1*Te)* im/R1, the elevator operation energy balance computing formula of elevator operation has infinite shape changeable, deduction;

Quality of elevator comprises lift car gross mass or counterweight quality or comprises lift car gross mass and to heavy simultaneouslyAmount, the type setting of the parameter of quality of elevator need determine according to the signal value position of driving source parameter, when driving source ginsengWhen the signal value position of the number steel wire rope that is cage side, quality of elevator can be selected lift car gross mass (it comprises skyCarry car quality and delivery article quality); When the signal value position of driving source parameter is traction sheave and front end (traction thereofDrive disk assembly or motor or motor driver or supply unit etc. in the middle of wheel or traction sheave and motor) time,Quality of elevator can be selected lift car gross mass and counterweight quality; When the signal value position of driving source parameter is to heavy sideWhen steel wire rope, quality of elevator can be selected counterweight quality;

The present invention's " described elevator operation energy balance is calculated associated with elevator traffic direction " is also " to move according to elevatorDirection is adjusted the algorithm that described elevator operation energy balance is calculated ", refer to a kind of technical scheme, this calculating scope of applicationCharacter, not must be in the time of certain traffic direction could unfolding calculation;

For example can be in the time that elevator zero-speed be moved, the safety margins threshold values of the electric driving force parameter of use elevator and mass carriedCurrency calculates the value of speed uplink and/or up acceleration, operation upper limit valve when this value can be used as ascending for elevator conventionallyValue; For example can be in the time that elevator zero-speed be moved, by preset instructions value and the delivery matter of downstream rate and/or descending accelerationThe value of the driving source parameter that the currency of amount calculates, this value is generally used for judging when elevator is descending that driving source parameter is (as steel wireThe comprehensive pulling force of rope) no the transfiniting of meeting;

" elevator operation energy balance is calculated associated with elevator traffic direction " of the present invention, comprises that following traffic direction closesConnection 1, any one or two schemes in traffic direction association 2, and according to this traffic direction associated 1 and/or operationThe incidence relation that directional correlation 2 is out of shape, derives from; Do not arrange by this association principle at ascending for elevator, elevator downlink time divisionCalculate formula;

Traffic direction association 1: in the time of ascending for elevator: the weight component (m2*g) that mass carried m2 and gravity acceleration g produceFor energy absorption factor, the weight component (m3*g) that counterweight quality m3 and gravity acceleration g produce is energy release factor;In the time that elevator is descending: the weight component that mass carried m2 and gravity acceleration g produce is that energy discharges factor, to heavyThe weight component that amount m3 and gravity acceleration g produce is energy absorption factor; According to this energy absorption/or release rule existIn the different traffic direction of elevator, mass carried m2 is arranged to different computing formula from counterweight quality m3; For example aftermentionedShown in computing formula 3-1, formula 4-1, formula 4-2, formula 3-2, formula 4-3, formula 4-4;

Traffic direction association 2: when ascending for elevator and elevator are when descending, the gravity that quality of elevator and gravity acceleration g produceThe computing formula of component is constant, but in the time that ascending for elevator, elevator are descending the positive-negative polarity of handover source kinetic parameter;

As with reference to aftermentioned formula 3-1, when ascending for elevator, adopt computing formula 3-100:

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

When elevator is descending, adopt computing formula 3-101:

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

Or in the time that elevator is descending, do not change the form of computing formula 3-100, but substantial (T1/R1) switchedFor negative value; As force when the ascending for elevator T1 be on the occasion of, in the time that elevator is descending, forcing T1 is negative value.

In above-mentioned traffic direction association 2, in the time that ascending for elevator, elevator are descending, the positive-negative polarity of handover source kinetic parameter is mustMust step.

As can be seen here, in the time of the non-zero-speed operation of elevator, it is to have that elevator operation energy balance is calculated associated with elevator traffic directionNecessary, otherwise will cause the result of calculating to be made mistakes. And in actual applications, traffic direction association 1 is closed than traffic directionIt is clear succinct that connection 2 is wanted; Traffic direction association 1 more meets elevator energy flow in service to rule; Because use driving source parameterPositive and negative embodiment motor operating condition, than more scientific with the positive and negative embodiment elevator traffic direction by driving source parameter; Operation sideEasily make calculation expression complicated, chaotic to associated 3.

The present invention " adjusts the computational methods of described efficiency factor " according to motor operating condition, in the present invention referred to as " rootAdjust described efficiency factor according to motor operating condition ", it comprises in following motor operating mode association 1, motor operating mode association 2Any one or kinds of schemes, and according to this motor operating mode associated 1 and/or associated 2 distortion of motor operating mode, derive fromIncidence relation; :

Motor operating mode association 1: when motor is during in motoring condition, it is mechanical energy that motor absorbs electric energy conversion, according to energyConservation principle, this electric driving force parameter multiplies each other with the efficiency factor (as Kem1) that is less than 1;

Motor operating mode association 2: when motor is during in motor braking state, motor absorbs mechanical energy and is converted into electric energy, according toConservation of energy principle, this electric driving force parameter is less than 1 efficiency factor (as Kem2) divided by one;

The present invention " carries out the type setting of described electric power " according to motor operating condition, in the present invention referred to as " rootCarry out the setting of described electric power according to motor operating condition ", it comprises following motor operating mode association 3, motor operating mode passAny one or kinds of schemes in connection 4, and according to this motor operating mode associated 3 and/or associated 4 distortion of motor operating mode,The incidence relation deriving from;

Motor operating mode association 3: when motor is during in motoring condition, it is mechanical energy that motor absorbs electric energy conversion, now this electricityWhen qigong rate is chosen as motoring condition, the power of electrical system is (as the electricity of the device such as power supply or motor driver or motorMoving state power);

Motor operating mode association 4: when motor is during in motor braking state, motor absorbs mechanical energy and is converted into electric energy, nowWhen this electric power is chosen as motor braking state, the power of electrical system is (as electrification feedback braking power P4 or energy consumptionBraking power P5 etc.);

The associated principle of velocity variations situation of elevator is as follows: when Accelerating running, and the shift force that quality of elevator and acceleration produceComponent is energy absorption factor; While running slowly, the shift force component that quality of elevator and acceleration produce be energy discharge because ofElement; While traveling at the uniform speed, acceleration is zero, and the shift force component that quality of elevator and acceleration produce is also zero.

The present invention's " carrying out described elevator operation energy balance according to elevator speed changing condition calculates ", comprises according to above-mentionedThe associated principle of velocity variations situation is carried out following speed change associated 1 and/or speed becomes associated 2 processing etc.;

The parameter that the described elevator operation of associated 1. participation of speed change energy balance is calculated comprises acceleration;

Speed becomes the velocity variations situation of associated 2. identification elevators, carries out respectively described electricity traveling at the uniform speed, when variable-speed operationLadder operation energy balance is calculated or is processed.

The identification of velocity variations situation, can identify by acceleration aj value: in the time that elevator moves, aj is 0 or is less than a certainWhen default threshold values, can identify current velocity variations situation is that non-zero travels at the uniform speed; When aj is not 0 or is greater than certainWhen one default threshold values, can identify current velocity variations situation is variable-speed operation; Wherein, acceleration aj value can be adoptedWith aforementioned multiple obtain manner (as by acceleration transducer or speed Vq or rotation speed n 1 etc.); Also can be by electricityThe acquisition of information of machine driver is (as existing frequency converter generally has the at the uniform velocity information such as overcurrent, acceleration overcurrent, by this informationCan extraction rate changing condition); Also has more easy mode, by distinguishing velocity variations situation running time, as motorThe Accelerating running time of driver (as frequency converter etc.) is 2 seconds, and being set within 3 seconds after startup is variable-speed operationTime period, 3 seconds afterwards for non-zero travels at the uniform speed the time period;

Preferably, the parameter that participates in the calculating of described elevator operation energy balance comprises acceleration, and this acceleration is according to addingVelocity sensor measures. Acceleration according to the account form such as detection speed or rotation speed change gained: aj=(Vq_1-Vq_ 0)/t; First which obtains detection speed Vq, in the time of elevator low cruise, because Vq is much smaller than full scale, causes surveyingAmount error is large, is especially that this error is larger, substantially cannot be practical approaching zero-speed operation; And according to acceleration sensingDevice records acceleration, has response soon and the high advantage of precision, can be good at being applicable to low cruise, especially zero-speedMove, improve significantly the estimation precision of parameters of elevator run;

The more important thing is: because no matter elevator is up or descending, first inevitable from zero-speed, progressively accelerate at the uniform velocity;First in the time of zero-speed, judge whether it overloads/whether this abandons moving/sending alarm signal; Then just can carry out target accelerationThe planning of science activities of degree/target acceleration time, target velocity; Once in the future because Cost Problems has been abandoned in current car suddenlyYour scales double recipe case, now, acceleration transducer acceleration measurement and then calculate knot mutually by elevator operation energy balanceClose and weigh, it improves significant for elevator overload/be also elevator safety operation, efficiency.

Because in service at elevator, must experience startup, zero-speed operation, Accelerating running, travel at the uniform speed, run slowly,The steps such as zero-speed operation, shutdown; When calculating, employing speed becomes association 1, or associated 2 modes of speed change, just can obtain standardTrue result.

For example, calculate lift car gross mass m2 according to the driving source parameter of elevator and system operational parameters, m2 isThe join operation value directly obtaining; Calculate again delivery article quality m1 or unloaded car according to lift car gross mass m2Quality m0, m1 or m0 are the join operation value indirectly obtaining;

Join operation value of the present invention, for any one parameter (as m2/ or m1/ or m0) is according to join operation gainedNumerical value, and this numerical value is relatively complete for this measuring and calculating object, the reality of this parameter is not cut apart or rejected to this parameterValue; Apparent, actual value described in the present invention, be generally a certain attribute of certain object naturally, real numerical value;

For example: the join operation of delivery article quality is worth available m1 and represents, a reference value can represent with m1_org; For example:The join operation of lift car gross mass is worth available m2 and represents, a reference value can represent with m2_org; Indicate 1 especially: forBe convenient to describe and those skilled in the art understand the present invention: when measuring and calculating object is while being mass carried, join operation value or non-Closing operation values all can directly represent with parameter name m1 or m2; When measuring and calculating object is driving source parameter or system operational parametersTime, the expression formula of join operation value may add a suffix: _ cal after parameter name; As the parameter name aj of acceleration, connectionClosing operation values aj_cal represents; As the parameter name V1 of speed uplink, join operation value represents with V1_cal; As Q pointThe comprehensive pulling force parameter F1 by name of steel wire rope, this join operation value represents with F1_cal or μ 1_cal; All suffix areThe data of (_ cal), represent that these data are the join operation value by calculate gained based on elevator operation energy balance, withThe data that other modes (as measured value or artificial set-point or system default value) are obtained distinguish.

Described in 8A11., elevator operation energy balance is calculated associated with elevator traffic direction;

8A12. is in the time that described elevator moves with zero-speed, and described join operation value and described reference data only come from a kind of parameterObtaining system, is also that described join operation value and described reference data are all to calculate gained based on elevator operation energy balance.

The implementation of this method for supervising (#1):

This method for supervising (#1) is on the basis of invention thought of the measuring method of previously described a kind of parameters of elevator runA continuity, this continuity is to monitor elevator to move whether safety is object;

The core procedure 1 of this method for supervising (#1): the join operation value of obtaining the measuring and calculating object of described elevator; The present inventionCarry out deep study and analysis by the structure to counterweight formula elevator and operation principle, calculate and ask according to elevator operation energy balanceGo out to calculate the join operation value of object (as delivery article quality m1);

Obtain the join operation value of described measuring and calculating object, can realize by multiple obtain manner; As read other systemThe join operation value of output; As measured the join operation value of elevator by monitoring system self measurement component; Or part is for readingGet existing equipment output data, part is self measurement data etc.;

Obtain the join operation value of the measuring and calculating object of elevator, specifically can with reference to following aforementioned many embodiment (as embodiment 1,Embodiment 2, embodiment 3, embodiment 4, embodiment 5 etc.) carry out:

The core procedure 2 of this method for supervising (#1): according to the reference data of described join operation value and described measuring and calculating objectWhether the energy transmission situation that judges described elevator is abnormal;

Reference data of the present invention, is the reference data of calculating object, the number of also identifying for energy transmission situationAccording to, be also that energy transmits situation identification data, refer to for coordinating with described join operation value and carry out energy transmission and extremely sentenceDisconnected/data or numerical value relatively, this be because individual data cannot complete comparison/judge computing. Reference data bagDraw together in a reference value, permissible aberration value, the first reference value any one or several data; Described in the present invention, a reference value is alsoFor a reference value of energy transmission situation identification, it is also energy transmission situation identification a reference value; License described in the present invention partiallyDifference, also for the deviate of energy transmission situation identification, is also energy transmission situation identification deviate;

A kind of technical scheme of theme that the present invention sets forth, described a reference value, it must consider practicable technological meansOr implementation, its value is naturally tied in concrete Selecting time and/or value mode; According to reference number described laterAccording to the concrete plan of establishment (as the choosing of the source of data or value approach, setting means, Selecting time etc.) andRelated embodiment (embodiment 1-10), apparent learning: according to measuring and calculating object difference and/or actual value settingThe difference of mode, a reference value of the present invention have multiple different Selecting time scope, multiple different codomain, can be by manyPlanting different technical method or schemes realizes.

A reference value of the present invention is a numerical value that is subordinated to measuring and calculating object type and/or actual value set-up mode, is oneThe concept of individual amplitude (also big or small) is intermediate layer data; A reference value of the present invention is generally the survey with elevatorThe actual value resembling in the time of join operation value value of getting it right approaches or equal numerical value; Described herein is common, refers to most of feelingsCondition, most of time, the amplitude range of this reference value goes for the measuring and calculating object of most of types, as driving source ginsengNumber, mechanical operating parameters; As shown in embodiment 7,9, when the setting means of a reference value is according to getting with join operation valueWhen measured value when value in same time range is set, this reference value (being also measured value) is generally right with the measuring and calculating of elevatorThe actual value resembling in the time of join operation value value approaches or equal numerical value;

As described in Example 6: when the setting means of a reference value fortune of combining for obtaining according to (meeting while imposing a condition)When calculation value is set, this reference value also naturally for the join operation value of this while imposing a condition " (a certain specific) meet "Approach or equal numerical value; Because " (a certain specific) meets while imposing a condition " is (use that user or system are specially specifiedIn reference data is set) time, conventionally can be defaulted as now elevator and work in normal condition, this reference value (is alsoThis join operation value) be generally and approach in the actual value of " (a certain specific) meets while imposing a condition " measuring and calculating objectOr equal numerical value; The setting means of this kind of a reference value be conventionally applicable to when measuring and calculating object be quality of elevator (m0, m1,M2, m3) or when the intrinsic parameter of system; In the time that measuring and calculating object is quality of elevator, because " elevator is by moving in samePower apparatus controlling run " time period in the value of quality of elevator conventionally change little, so the numerical value of this reference value is conventionally stillSo may be with the measuring and calculating object of elevator in (transmitting obtaining of situation abnormal judgement for energy) join operation value valueTime actual value approach or equate;

As described in Example 8: when the setting means of a reference value is when setting according to system default value, this reference value (alsoI.e. this system default value) be generally and the actual value phase of this measuring and calculating object system default (being also under standard state conventionally)Deng or approaching numerical value, be generally calibration value; It is system that the setting means of this kind of a reference value is applicable to when calculating object conventionallyWhen the fixing quality of elevator (m0, m3) of intrinsic parameter or amplitude.

Energy of the present invention transmits situation extremely can be abnormal referred to as energy transmission, and energy transmission of the present invention is wrapped extremelyDraw together in following A 1-1, A1-3 any one or multiple situation:

A1-1. the difference of described join operation value and described a reference value exceeds described permissible aberration value;

A1-3. described join operation value exceeds the first reference value of described measuring and calculating object;

Analyze from inventive principle and basic technology scheme and effect, above-mentioned A1-1 situation substantial equivalence is in A1-3;

Wherein, described permissible aberration value comprises any one or more data in upper limit deviate, lower limit deviate; On thisLimit deviate is the upper limit deviate for the identification of energy transmission situation, is also energy transmission situation identification upper limit deviate;This lower limit deviate is the lower limit deviate for the identification of energy transmission situation, is also energy transmission situation identification lower limit deviationValue;

Described the first reference value comprises any one or more numbers in the first reference value higher limit, the first reference value lower limitAccording to; Of the present invention exceeding comprises and is greater than certain higher limit, is less than any one or the multiple situation such as certain lower limit;

Described A1-1 situation comprises in following A 1-1-1, A1-1-2 any one or two kinds of situations;

A1-1-1. the difference of join operation value and a reference value is greater than upper limit deviate;

A1-1-2. the difference of join operation value and a reference value is less than lower limit deviate;

Described A1-3 situation comprises in following A 1-3-1, A1-3-2 any one or two kinds of situations; ;

A1-3-1. described join operation value is greater than the first reference value higher limit;

A1-3-2. described join operation value is less than the first reference value lower limit;

In sum, the first reference value=a reference value+permissible aberration value, permissible aberration value has upper limit deviate or lower limitAt least one in deviate, what the first reference value was corresponding has the first reference value higher limit and the first reference value lower limit,The first reference value higher limit be a reference value add one on the occasion of, the first reference value lower limit is that a reference value adds a negative value or deductsOne on the occasion of.

When permissible aberration value has upper limit deviate and does not have lower limit deviate: whether be greater than first according to join operation valueReference value judges that the energy of elevator transmits situation and whether occurs extremely, in the time that join operation value is greater than the first reference value, to sayBright energy transmission situation occurs abnormal, otherwise no exceptions;

When permissible aberration value has lower limit deviate and does not have upper limit deviate: whether be less than first according to join operation valueReference value judges that the energy of elevator transmits situation and whether occurs extremely, in the time that join operation value is less than in the first reference value,Illustrate that energy transmission situation occurs abnormal, otherwise no exceptions;

When permissible aberration value has upper limit deviate and lower limit deviate simultaneously: first reference value higher limit=a reference value+upper limitDeviate, whether first reference value lower limit=a reference value+lower limit deviate, be less than the first reference value according to join operation valueLower limit and join operation value whether be greater than the first reference value higher limit judge elevator energy transmit situation whether occur differentOften, when join operation value be greater than the first reference value higher limit and join operation value be less than the first reference value lower limit any oneWhen establishment, illustrate that energy transmission situation occurs abnormal, otherwise no exceptions.

Should be understood that the first reference value=a reference value × proportionality coefficient, now permissible aberration value=a reference value × ratio systemNumber-a reference value. If proportionality coefficient is 0.8-1.1, upper limit deviate=0.1 × a reference value, lower limit deviate=-0.2 ×A reference value.

As a rule, it is little of to improve the sensitivity of monitoring that permissible aberration value is tried one's best, but the value that must keep certain quantity withReduce the false triggering rate of monitoring; Because permissible aberration value numerical value is little, can be far away according to the first reference value higher limit of its settingLower than the safety margins threshold values of measuring and calculating object; So method for supervising provided by the invention (#1) can be broken through existing known skillArt is not easy to carry out the limitation of security monitoring in the time that parameters of elevator run does not exceed safety margins threshold values:

The core procedure 3 of this method for supervising (#1): carry out in following 8B1,8B2 any one or kinds of schemes processing;The operating energy transmission of elevator extremely likely causes serious security incident, needs response in time to process; If not in timeResponse/or start relevant safe handling measure; This monitoring will not have practical significance.

Embodiment 6,7,8,9 and respectively substitute or extend in embodiment, described permissible aberration value, has all adopted system pre-If value or historical record value, also can adopt simpler mode, as join operation value or a reference value of measuring and calculating object are multiplied byA coefficient is as permissible aberration value, and this coefficient can be by user depending on field demand arbitrary decision (as get 0.1 or 0.3 etc.),Or and then set the first reference value according to this permissible aberration value, carry out energy transmission situation judgement and subsequent treatment; Also canNot set permissible aberration value, can directly set the first reference value, if the higher limit of this first reference value of setting is for being greater thanThe actual value of described measuring and calculating object and be less than certain numerical value in the safe threshold values of the limit; As the lower limit of this first reference value of settingValue is certain numerical value that is less than the actual value of described measuring and calculating object.

In method for supervising provided by the present invention (#1), the value that preferred version is all parameters is Real-time Obtaining, steps A,B is real-time execution, and carries out with the time cycle circulation of setting, and the cycle period of this setting is for more short better, moreShortly just more can improve the sensitivity monitored and ageing. Certainly, also can be non real-time, or intermittent execution.

The value of parameter is (as a reference value, calculating join operation in join operation value, reference data are worth required input parameterValue) Selecting time and the explanation of acquisition time; Selecting time of the present invention, refers to the parameter rise time, refers to calculateThe corresponding time of value of the required input parameter of this parameter; Because obtained various ways (read, measurement etc.);As read in front 100 milliseconds of parameter values that generated of time1 time, the acquisition time of this parameter is time1, but shouldThe time of first 100 milliseconds when the Selecting time of parameter is time1;

In method for supervising of the present invention (#1), when described measuring and calculating object is arbitrary ginseng in driving source parameter, mechanical operating parametersWhen number, more excellent scheme be all parameters (as a reference value in join operation value, reference data, to calculate join operation value requiredThe value of the input parameter of asking) all in default time range, value (as far as possible synchronous), real-time calculating, Real-time Obtaining (are readGet or measure) join operation value and reference data, real-time judge, dispose judged result in real time, at this moment, the getting of parameterThe value time can be equal to acquisition time;

In method for supervising (#1), when described measuring and calculating object is in quality of elevator, the intrinsic parameter of system when any one parameter,The more excellent mode of the Selecting time of join operation value (being worth the value of required input parameter together with calculating join operation) is for allValue in default time range (synchronous) as far as possible, in real time calculating, Real-time Obtaining (read or measure), carry out in real timeEnergy transmission extremely judges/monitors; But the Selecting time of reference data or setting-up time do not need and the getting of join operation valueThe value time at one time; The acquisition time (only need read) that carries out the reference data before the abnormal judgement of energy transmission withThe Selecting time of reference data allows different;

The control mode 1 of the Selecting time of parameter value: on stricti jurise, obtain at one time the value of multiple parameters,May be inconvenient to realize; In actual mechanical process, after the Selecting time of the value of each parameter group has before may having, at this momentOnly the Selecting time of the value of each parameter need to be controlled in a default time range, this default time range can rootThe software processing speed on border, Hardware Response Delay speed and determine factually; As desirable 100 milliseconds, or 10 milliseconds, or 1 millimeter,Or 0.1 millisecond; This default time range time is shorter, calculate/monitor precision higher, but system cost also increases;

The control mode 2 of the Selecting time of parameter value: if elevator service condition is substantially constant, the speed of for example elevator existsWithin 10 seconds, all maintain 1m/ speed and travel at the uniform speed, get the currency of speed, or value described 10 seconds first of time, withThe value when tail of described 10 seconds, effect is the same; So the default time range of the Selecting time of each parameter value canAdjust according to elevator service condition, also in the time that elevator service condition is constant, can obtain this parameter constant in service conditionValue on Shi Renyi time point.

The Selecting time of above-mentioned parameter value, the explanation of acquisition time are applicable to the arbitrary embodiment of the present invention.

Described the first reference value, permissible aberration value in the present invention, can set by systemic presupposition value, has various ways to establishFixed, such as by the experimental method of limited number of time, artificial trial and error procedure, the methods such as type approval test method are set.

The implementation detail of scheme 12A1: see embodiment 6,7,8 and alternative and/or extension embodiment thereof;

The implementation detail of scheme 12A2: under normal circumstances, the setting principle of the permissible aberration value of measuring and calculating object is: this valueNeed little to improve the sensitivity of monitoring as far as possible, but can not be too small to reduce the false triggering rate of monitoring; In like manner, firstThe setting principle of reference value is also: be exactly to approach a reference value of measuring and calculating object as far as possible but must keep suitable poor with a reference valueValue; As the higher limit of the first reference value being made as to 1.2～1.5 times of a reference value, or the lower limit of the first reference value is made as0.7～0.9 times of a reference value, or upper limit deviate is made as 0.1～0.3 times of a reference value, or lower limit deviate is made as to baseAccurate-0.3～-0.1 times of being worth; But the accurate setting of this reference data, as leaned on artificial trial and error procedure, or empirical method goes slowly to touchRope, goes slowly to verify, reference data Adjusting accuracy is low, efficiency is low; And machine condition, year condition when different elevator operation becomeChange multifariously, more increase the difficulty of the accurate setting of reference data.

(highest priority is permissible aberration value wherein to set described reference data according to the historical record value of described measuring and calculating objectOr first reference value), be one of method for optimizing;

In the time that described historical record value has generated, can set described reference data according to historical record value and (as carry out followingAny one or plurality of step in 9A2_1,9A2_2,9A2_3);

9A2_1. sets described permissible aberration value according to the difference of described historical record initial value and described historical record a reference value;

14A3 restarts energy and transmits failure monitoring mechanism in the time that the energy transmission that detects elevator is abnormal;

The implementation detail explanation of this this 11A1 scheme:

Energy transmission generally includes that elevator running environment is abnormal, energy transmits fault etc. extremely; Typical elevator running environmentExtremely comprise and carry condition abnormal (as beated in elevator or significantly rock/article roll extremely) etc.;

Energy transmits fault two kinds of identifications and processing mode; One for adopting 14A1 scheme, according to join operation value, ginsengExamine data, running environment information and directly judge whether to occur energy and transmit failure condition, this 14A1 scheme also can be described as withStep type energy transmits failure monitoring mechanism;

As normal in measured external environmental information and that energy transmission has occurred is abnormal, can directly judge that elevator is in energyTransmit fault state; As measured external environmental information has abnormal conditions and that energy transmission has occurred is abnormal, can judgeThe current energy transmission of elevator may be to cause because of external environment condition extremely; Elevator can continue to send energy transmission and extremely warnInformation but not energy transmit fault message; Elevator can be proceeded to monitor to move and judge that extremely whether energy transmission with fortune simultaneouslyThe elimination of row environmental abnormality and eliminating, if can not synchronism eliminates or energy transmission extremely continue to be greater than setting-up time, stillSo can judge that energy transmits fault;

Whether elevator running environment is abnormal, can be by obtaining the running environment information of (read or measure) elevator and then carrying outIdentification judgement; Running environment information have a multiple obtain manner: can by relevant vibrating sensor, optics, ultrasonic wave,The facility such as infrared sensor, radar is measured identification; Also can distinguish above-mentioned situation by visual identification by operating personnel; DescribedThe Selecting time of the Selecting time of join operation value and described running environment information is all in default time range.

Energy transmits fault and mainly comprises: in guide rail and/or elevator hoistways, the frictional force of object and car extremely or personnel's quiltExtremely snap in the inordinate wear of elevator hoistways, elevator revolving part, aging, explosion, fracture, rotor seize etc.; WhenThe energy of elevator transmits failure monitoring mechanism to be confirmed to occur energy and transmits fault, conventionally need at once start deceleration, shutdown,The emergent management such as fault warning or inverted running scheme.

The useful meaning of this 14A1 scheme: transmit failure monitoring mechanism by energy, energy is distinguished in identification that can be more deepTransmit the formation reason (whether running environment abnormal or no energy transmits fault) of unusual condition, thereby be convenient to makeMore suitable safe handling response (only need be sent voice as caused energy transmission abnormal because of personnel's beating in elevator timePrompting or warning, as transmitted when fault and need to slow down, shut down even reversion etc. because of energy).

The useful meaning of this 14A2 scheme: no matter calculate the type of object, at any time, by described mass carriedNumerical value output (to the man-machine interface of the interior man-machine interface of car and/or Room door), contributes to elevator passenger a glance to identify elevator fortuneWhether row is normal, is of great importance for the safe operation of elevator;

Preserve the join operation value of delivery article quality, as the black box function of aircraft safety, be convenient to ex-post analysis.

According to the description of the combined parameter of aforementioned driving source, electric power capable of being combined go out electrical energy; The present invention also allows to makeBy the combined parameter of driving source of kind of energy (as the power consumption of section or the summation of section acting sometime sometime)As measuring and calculating object; Power and energy are easily obscured from physical concept, but for elevator operation, both meaningsDifferent; Power is energy time differential, has moment-concept fast, energy be power in timeAccumulative total, has the concept of time-lag-at a slow speed; Transmit abnormal monitoring so carry out energy by scheme provided by the invention,Preferably use the instant value (as instantaneous power, moment torque, moment driving force, immediate current etc.) of driving source parameter to enterThe real-time energy of row transmits abnormal monitoring; If using the combined parameter of driving source of kind of energy to carry out energy transmission supervises extremelyControl effect, needs the time of energy accumulative total to control the smaller the betterly (as 100 millimeters, 10 milliseconds, 1 millisecond, 0.1Millimeter).

If it is abnormal to carry out energy transmission by the combined parameter of driving source of kind of energy as measuring and calculating object, also need to possess coreStep in heart bracket (obtain measuring and calculating object join operation value, set reference data, according to join operation value and reference numberAccording to judging that whether energy transmission situation is abnormal, the judged result of energy transmission situation is had to clear and definite processing scheme), can joinAccording to following embodiment 10:

Embodiment 10: this method for supervising (#1) comprises steps A, B, C;

Steps A 1: with reference to the method for previous embodiment 5, the energy flow of identification elevator is to operating mode (electronic up, motorBrake up, electronic descending, motor braking is descending), identification elevator velocity variations situation (non-zero travels at the uniform speed, addsSpeed is moved, is run slowly), first obtain each parameter (the efficiency system of motor in (read or measure) same time rangeThe efficiency factor Km1 of number Ke1 and/or Ke2, machine driven system and/or Km2, comprehensive gearratio im, unloaded sedan-chairRailway carriage or compartment quality m0, counterweight quality m3, speed uplink V1, downstream rate V2) value, according to different energy flows to workCondition and velocity variations situation are carried out in following 10A1-1,10A1-2,10A1-3 any one or multiple calculating, calculate electricityThe join operation value Pm_cal of the electric power of machine, computing formula is as follows:

10A1-1. when energy flow be electronic up to operating mode, and velocity variations situation is non-zero while traveling at the uniform speed, according underState the join operation value Po_cal of the electric power of formula 4-26 measuring and calculating motor;

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

10A1-2. when energy flow be electronic descending to operating mode, and velocity variations situation is non-zero while traveling at the uniform speed, according underState the join operation value Po_cal of the electric power of formula 4-27 measuring and calculating motor;

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

10A1-3. when elevator be motor braking up+non-zero is while traveling at the uniform speed, generate electricity back according to following formula 4-28 measuring and calculatingJoin operation value P4_cal or the resistance dynamic braking power P5_cal of feedback braking power;

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

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

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

And then above-mentioned join operation value Po_cal or P4_cal or P5_cal are carried out to computing (as integration) and obtain 2Electrical energy value EM1_cal within second, EM1_cal is the join operation value indirectly obtaining;

Steps A 2: obtain Pm_cal and EM1_cal value while above-mentioned, obtain and (read motor driver measuring and calculating gainedData or measure with power meter) electric power a reference value Pm_r, and then to Pm_r integral operation to obtain and EM1_calThe measured value EM2 of the electrical energy in 2 seconds of the same period, or obtain EM2 value with direct measurement of power electric meter;EM2 is as with reference to a reference value in data; Set permissible aberration value EM_def3:EM_def3=EM2/10, or EM_def3=EM1_cal/8；

Steps A 3: carry out following 2 energy and transmit in situation Rule of judgment any one or more: Rule of judgment 1:((EM1_cal-EM2)>EM_def3), Rule of judgment 2:((EM1_cal-EM2)<(EM_def3)),

Step B: be yes as 2 energy in steps A 3 transmit arbitrary judged result in situation Rule of judgment, start energyAmount is transmitted exception handling (as audio alert etc.);

The replacement scheme 1 of embodiment 10: can by energy calculate time cycle be made as 1 second from 2 seconds, 0.1 second, 0.01Second etc.; Time is longer, as is greater than 5 seconds 10 seconds etc., has lost energy and transmit the meaning of abnormal monitoring; Time is shorter,It is faster that energy transmits abnormal monitoring response, but (due to four inducements) of join operation value, measured value, reference dataMeasure error will be larger/and effect is poorer; As can be seen here, by driving source parameter or by combined driving source parameter (as energy)Energy as measuring and calculating object transmits abnormal monitoring effect, can not show a candle to right as measuring and calculating to mass carried or the intrinsic parameter of systemResemble.

Method for supervising when a kind of elevator lifting operation provided by the present invention and the beneficial effect of system (#1):

The present invention carries out deep study and analysis by the structure to counterweight formula elevator and operation principle: the operation essence of elevator justBe energy transfer process, also drive the power transmission process of elevator; The step of method for supervising provided by the invention (#1)In A, comprise step: obtain described elevator measuring and calculating object calculate gained join operation value based on elevator operation energy balance;In the elevator operation energy balance of elevator operation is calculated, elevator driving source parameter represents the information provision of power, elevator matterAmount represents the base attribute of driving force receptor, and the system operational parameters of elevator represents that basic condition that energy transmits is (as each germlineThe intrinsic parameter of uniting) and the mechanical operating parameters that produces under dynamic action of elevator be also that motion result is (as speed, accelerationDeng);

If (comprise that personnel are snapped into sedan-chair when the frictional force of object and car increases in the guide rail of elevator and/or elevator hoistwaysReason between railway carriage or compartment and elevator hoistways causes): if monitoring system is using driving source parameter as measuring and calculating object, at itWhen his relevant elevator service condition (as quality of elevator, speed, acceleration etc.) is constant, must expend more movingPower and cause the elevator operation energy balance of a reference value of driving source parameter and elevator operation to calculate gained join operation valueDeviate increases; If monitoring system is using mechanical operating parameters medium velocity as measuring and calculating object, as the driving source parameter of elevatorThe elevator service condition that a reference value is constant and other are relevant (as quality of elevator,, acceleration etc.) when constant, canCan cause a reference value of speed and the elevator operation energy balance of elevator operation of elevator to calculate the inclined to one side of gained join operation valueDifference increases; If using quality of elevator (as delivery article quality m1 or gross mass m2) as calculating object and otherWhen relevant elevator service condition (as acceleration etc.) is constant, will cause the elevator operation energy balance meter of elevator operationThe join operation value of calculating gained quality of elevator changes; So by join operation value and the reference data of measuring and calculating object are carried outRelatively, whether extremely just can judge the operating energy transmission of described elevator situation, and by follow-up energy transmissionTreatment step after situation judgement can be realized in time energy and transmit abnormal monitoring and early warning;

In the present invention, state is also situation, and both are equal to; It is also energy transmit mode that energy transmits situation.

Because elevator driving source parameter represent the information provision of power also represent the electric power system of elevator situation (depending onDevice in the supply unit of the collection point of concrete electric driving force parameter group signal and fixed elevator, motor driver, motorSituation); The system operational parameters of elevator represents the basic condition (parameter as intrinsic in various systems) that energy transmits, relevantElectric information efficiency factor embody the safe condition of electric power system, mechanical transmission component efficiency factor embodies machine drivingThe safe condition of parts, personnel are snapped into can be by the guide rail and/or elevator hoistways of elevator between car and elevator hoistwaysThe frictional force of object and car embodies, apparent, and energy described in the present invention transmits situation, is also energy transmission systemThe situation of system is especially and the situation of elevator rising or the directly related energy delivery system that declines also to drive elevator literFalling the situation of the power-transmission system of operation, is also that power transmits situation; This energy transmission situation is and lift running safetyThe situation being closely related; But not be only confined to the situation of device in car, in car device general with drive elevator liftingOperation does not have direct relation;

Comprehensive, judge that according to the reference data of described join operation value and described measuring and calculating object the energy of described elevator passesWhether the situation of passing is abnormal, has very great significance for the safety in operation tool of the energy delivery system that improves elevator; ItsSafe meaning is far more than the judgement of carrying out the similar device faults such as LOAD CELLS.

Because reference data is to set according to a reference value of measuring and calculating object (not according to safety margins threshold values), allowIt is much smaller than safety margins threshold values; So when parameters of elevator run does not exceed safety margins threshold values, be also convenient to realize (bagThe reason that the personnel of drawing together are snapped between car and elevator hoistways causes) elevator energy transmission monitors and early stage pre-extremelyAlert, be convenient to avoid to occur more serious, uncertain security incident (comprise wire cable rupture, elevator out of control etc.) as far as possible;As the cancer diagnosis of human medical, if just find conventionally to mean life termination late period, if early detection is meaned conventionallyLife is normally survived; So the technical program is significant for the safe operation of elevator.

28D embodiment explanation: above-mentioned 28A, 28B, 28C are the machinery fortune of carrying out described elevator in control system insideThe calculating of the value (join operation value) of line parameter; Also allow by value (connection outside, that other system carries out mechanical operating parametersClose operation values) calculating, only need its computational methods to adopt computational methods described in 28A, 28B, 28C; ReadShould be by value (join operation value) outside, that other system calculates gained mechanical operating parameters; According to described mechanical movement ginsengElevator operation described in the value control of number;

In the present invention, except calculating with formula/model, tabling look-up is also a kind of computational methods, and form calculates; OnState 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,Arbitrary formula, form in formula 28-6, the second association table, the first association table, all can be described as one and at least comprise instituteState the mass carried of elevator in the mapping relations of the mechanical operating parameters of interior parameter and this elevator;

Be worth the value action of the value of described mechanical operating parameters according to described mass carried, conventionally enter specific time a certainOK, as elevator is closed the door, is started before lifting operation operation; Certainly, the action of this value also can be carried out this and gets in lifting processValue, is selected voluntarily by user.

Certainly, in above-mentioned 28A, 28B, the arbitrary scheme of 28C, 28D, " according to the value control of described mechanical operating parametersDescribed elevator operation ", the described elevator operation of this control all accuses that the described elevator of system meets safety standard operation;

The core content of this control method they (four):

Foregoing solved the safety value of the mechanical operating parameters of controlling elevator operation source, how analyze according to fingerMaking elevator operation described in preset value, the control of operation upper limit threshold values, how following content carries out stepping, how if introducingAccording to class or the operation of centrifugal pump control elevator, particular content is as follows:

The core object of this control program is according to the License Value adjustment of mass carried (current actual value) and electric powerAscending for elevator speed, downstream rate; In the time that this mechanical operating parameters is speed uplink or downstream rate, when this " at least twoIndividual " when being only two, can simply be interpreted as high speed value, low speed value, (high speed value > low speed value); When this " at least twoIndividual " when being only two, also can be regarded as two different class of this speed, a top gear, a low or first gear, each classAll there is a respective value; The speed of low or first gear (speed of top gear >);

The special agree as follows of the present invention: " at least two " do not comprise that this this mechanical operating parameters is zero this this mechanical movement ginseng maybeNumerical value and zero difference are less than the situation of a preset value; The main purpose of this agreement be exactly for those skilled in the art understand andEasy to operate, in " at least two ", get rid of zero-speed.

When ascending for elevator or prepare when up, set also i.e. the 3rd preset value of a decision threshold, as large in the value of mass carriedIn the 3rd preset value, export the instruction preset value of a speed uplink; As being less than the 3rd, the value of mass carried presetsBe worth, export instruction preset values of another different sizes of this speed uplink; For example: when delivery article quality value withThe absolute value of the difference of equilibrium valve is less than the 3rd preset value, the instruction preset value using high speed value as speed uplink/or fortuneRow upper limit threshold values, or control described elevator and run on top gear; When delivering the exhausted of the value of article quality and the difference of equilibrium valveValue is more than or equal to the 3rd preset value, the instruction preset value using low speed value as speed uplink/or operation upper limit threshold values,Or control described elevator and run on low or first gear;

When elevator is descending or prepare when descending, in the time that these " at least two " are three, three speed can simply be interpreted as " heightSpeed value, middling speed value, low speed value ", high speed value is greater than middling speed value, and middling speed value is greater than low speed value; Also can be regarded as this speedThree different class, a top gear, a mid ranger, a low or first gear, the speed of top gear is greater than the speed of mid ranger, inThe speed of speed shelves is greater than the speed of low or first gear; As set two decision threshold that vary in size (also i.e. the 4th preset value, theFive preset values), the absolute value of the delivery value of article quality and the difference of equilibrium valve is simply divided into large, medium and small San Ge districtBetween; For example: the absolute value of the difference of equilibrium valve and 0 can be made as to maximum difference, or nominal load capacity and equilibrium valve is poorThe absolute value of value is made as maximum difference; (the 0 < four preset value < five preset value < maximum difference), " little " district is 0 toThe interval of four preset values, " in " district is the interval of the 4th preset value to the four preset values, " greatly " district is that the 5th preset value arrivesThe interval of maximum difference; When the absolute value of the delivery value of article quality and the difference of equilibrium valve is during in " greatly " district, generalLow speed value is as the instruction preset value of speed uplink/or operation upper limit threshold values, or controls described elevator and run on low or first gear;When the absolute value of the delivery value of article quality and the difference of equilibrium valve in " in " when district, using middling speed value as upper scanning frequencyThe instruction preset value of degree/or operation upper limit threshold values, or control described elevator and run on mid ranger; When delivery article qualityValue with the absolute value of the difference of equilibrium valve in the time of " little " district, the instruction preset value using high speed value as speed uplink/Or operation upper limit threshold values, or control described elevator and run on top gear;

Certainly, above-mentioned according to the 3rd preset value, the 4th preset value, the 5th preset value subregion, be only an example, notLimit; User can be with reference to which, adjusts voluntarily each preset value, subregion voluntarily;

Therefore,, in the time that these " at least two " are limited number (as 4,5,6,8 etc.), its essence is this mechanical movementParameter value be multiple centrifugal pumps, according to these multiple centrifugal pumps, elevator is divided into many grades and controls. As for above-mentioned heightThe speed of speed value/top gear, the speed of middling speed value/mid ranger, the speed of low speed value/low or first gear, the concrete size of its value,Can determine according to schemes such as the experiment of type approval test setting, limited number of time, artificial trial and error procedures, also can be with reference to above-mentioned arbitrary mappingRelation (formula or form) is set. All preset values herein, all can be according to type approval test setting, limited number of timeThe schemes such as experiment, artificial trial and error procedure are determined.

According to 28A, 28B, 28C, 28D scheme, in fact allow more class/centrifugal pump, or even stepless time adjustment,So that elevator in zero load between fully loaded when arbitrary load capacity, all can improve elevator operating efficiency;

The core content of this control method they (five):

While analyzing various load situation (as zero load, underloading, counterweight balance, heavy duty, fully loaded), with mechanical operating parametersThe relation of safety value (being especially the License Value of speed);

(five .1)

Apparent, in the time that the currency of delivery article quality is zero (m1=0), be zero load; When delivery article qualityCurrency while equaling the nominal load capacity m1_ena (m1=m1_ena) of elevator for fully loaded; Because of research object of the present inventionFor there being the elevator of counterweight, and this counterweight quality m3 is greater than unloaded car quality m0 conventionally;

Show through above-mentioned formula 28-1,28-2,28-3-1,28-3-2,28-4-1,28-4-2 computational analysis: work as deliveryArticle quality value m1 and unloaded car mass value m0's and with the difference of counterweight mass value m3 more hour, pass through safetyThe License Value of the speed of checking and approving is larger; Analyze theoretically, when load product mass value m1 and unloaded car mass valueM0's and while equaling counterweight mass value m3 (also: m1+m0=m3), while being also the mass balance of traction sheave the right and left,The now License Value maximum of speed, the value of the delivery article quality m1 in this situation is equilibrium valve, the now load of elevatorSituation is called counterweight balance; Equilibrium valve is also the absolute value of the difference of counterweight mass value m3 and unloaded car mass value m0;Because equilibrium valve is generally the half of the nominal load capacity m1_ena of elevator, so counterweight balance also can be described as semi-load;

For the ease of understanding, the present invention agreement: when load product mass value be greater than zero and be less than the first preset value (0 < m1 <The first preset value) time be underloading; When load product mass value is more than or equal to the second preset value and is less than the payload ratings of elevatorIt when amount m1_ena (the second preset value≤m1 < m1_ena), is heavy duty;

(the first preset value≤the second preset value); For example, 0.5 times of the desirable equilibrium valve of the first preset value, second is defaultBe worth 1.5 times of desirable equilibrium valve; Certainly, this value first preset value, the second preset value can be adjusted by user; But conventionally, in order to understand facility, meet following Mathematical rule better: (0 < the first preset value < equilibrium valve), (equilibrium valve <The second preset value < m1_ena)

When elevator, more to level off to the License Value of full load speed uplink and/or downstream rate less;

Elevator is fully loaded when up, consumes electric power many, lower when the License Value weight/HP ratio balance of speed uplink; And this valueThe power safety value Po_ena (being generally equal to the rated power of motor) of motor while being limited by motoring condition;

Elevator is fully loaded when descending, lower when the License Value weight/HP ratio balance of downstream rate; And this value is limited by electric driving force systemThe ability to arrange jobs of system to braking power, with the power safety value Po_ena (being generally equal to the rated power of motor) of motorIt is irrelevant;

Different from conventional prejudice (while allowing weight/HP ratio balance when as descending in elevator underloading with higher, downstream rate faster): when elevator underloading descending (value that also delivers article quality m1 levels off to zero), consume electric power many,Now lower when the License Value weight/HP ratio balance of downstream rate; And the power safety value of motor when this value is limited by motoring conditionPo_ena (being generally equal to the rated power of motor);

Different from conventional prejudice (while allowing weight/HP ratio balance when as up in elevator underloading with higher, speed uplink faster): in the time that elevator underloading is up, lower when the License Value weight/HP ratio balance of speed uplink; And this value is limited by braking workSafety value P4_ena or the P5_ena of rate, with the power safety value Po_ena (being generally equal to the rated power of motor) of motorIrrelevant.

(five .2)

Comprehensive, from different with conventional prejudice, while being not elevator underloading, allow operation fast; The operation of control elevatorAscending for elevator speed and the desired value of downstream rate and the nyctitropic acceleration of each speed, operation upper limit threshold values, each classRespective value, all need can learn through deep safety compute; " controlling described elevator operation " of the present invention,Refer to " control elevator described in described elevator control and meet safety standard operation ";

The described safety standard that meets, in following safety condition 1, safety condition 2, safety condition 3 at least one;

Safety condition 2: as 28B, 28C, 28D scheme, be used for control by tabling look-up or obtaining this from outside, other systemThe join operation value of this mechanical operating parameters or the respective value of this class of elevator operation processed (are also instruction preset value or operationUpper limit threshold values), verify from result: this value is not more than the safety value of mechanical operating parameters;

The safety value of this mechanical operating parameters is moving according at least comprising mass carried (being preferably current actual value) and sourceThe parameter of force parameter (being preferably safety margins threshold values) is calculated gained (result as shown in embodiment 28A); CanWith what understand, it is safe moving with the value control elevator of this mechanical operating parameters;

Safety condition 3: for controlling the join operation value of this mechanical operating parameters of elevator operation or the respective value of this class(being also instruction preset value or operation upper limit threshold values) and the corresponding driving source parameter of mass carried (current actual value)Value be not more than the safety margins threshold values of this driving source parameter; Detailed description of the invention, the value of corresponding driving source parameter canDeformation formula by above-mentioned formula 28-1,28-2,28-3-1,28-3-2,28-4-1,28-4-2 is calculated gained.

(five .3)

According to foregoing, analysis is learnt, according to the respective value control of the join operation value of this mechanical operating parameters or this classThe operation of described elevator, when the value of delivery article quality is greater than zero while being also non-no-load running, also can follow following speed-regulating scheme1, in 2,3,4,5,6,7 at least one;

Speed-regulating scheme 1: when underloading or when heavy duty elevator the License Value of speed uplink, up should be less than counterweight balance timeThe License Value of speed;

Speed-regulating scheme 2: when underloading or when heavy duty elevator the instruction preset value of speed uplink, should be less than counterweight balance constantlyThe instruction preset value of speed uplink;

Speed-regulating scheme 3: when underloading or when heavy duty speed uplink operation upper limit threshold values, upper scanning frequency should be less than counterweight balance timeThe operation upper limit threshold values of degree;

Speed-regulating scheme 4: when underloading or when heavy duty elevator the License Value of downstream rate, elevator should be less than counterweight balance timeThe License Value of downstream rate;

Speed-regulating scheme 5: when underloading or when heavy duty downstream rate instruction preset value, downstream rate should be less than counterweight balance timeInstruction preset value;

Speed-regulating scheme 6: when underloading or when heavy duty downstream rate operation upper limit threshold values, should be less than counterweight balance scanning frequency at presentThe operation upper limit threshold values of degree;

The core content of this control method they (seven):

The control method of a kind of elevator operating efficiency provided by the present invention and the beneficial effect of system::

In the prior art of current elevator, no matter there are people or nobody to take, no matter load weight, all with same speed operation,This is poor efficiency, non-science, be unfavorable for energy-conserving and environment-protective;

Known by present specification content analysis, if want to control safely, efficiently elevator operation, need to overcome manyPlant technical barrier: need the deep counterweight quality m3 that understands to move the uniqueness impact bringing to elevator; Need to distinguish zero-speedThe various situations such as operation, variable-speed operation, non-zero travel at the uniform speed, need to distinguish electronic up, motor braking is up, electronicThe various energy flows such as descending, motor braking is descending are to operating mode; Need to be by quality of elevator, driving source parameter, system operation ginsengSeveral three kinds of parameters combine and carry out electricity according to factors such as the elevator operation characteristics of law of conservation of energy, Newton's law, uniqueness againLadder operation energy balance is calculated, the especially mechanical movement characteristic to elevator and the electric driving force parameter as driving source parameterProfound understanding, calculates with the elevator operation energy balance that realizes profound cross-cutting electromechanics combination; Carry out complicatedWhen elevator operation energy balance is calculated, also need to carry out that, motor operating mode associated with elevator traffic direction is associated 1, motor workCondition association 2, motor operating mode association 3, motor operating mode association 4, speed become the pass of the Various Complex such as association 1, speed change associated 2Online is calculated; Need to overcome all conglomerate prejudice, need to carry out many creative analysis and research, just likely draw and meet peaceThe mechanical operating parameters of full specification (acceleration when speed uplink, downstream rate, acceleration are up, is slowed down adding when descendingOne or more parameters in speed) safety, control elevator operation efficiently;

Inertial thinking in industry field may think, elevator speed is not suitable for regulating, the meeting of may having thought speed heightDamage safety, the speed of service is fast may easily cause wire cable rupture, all belongs to industry prejudice; Industry prejudice may be recognizedCan be regardless of for ascending for elevator speed, downstream rate, need not distinguish motoring condition, motor braking state; Even if distinguishedMotor braking state, also may think under on-position speed higher/generated energy is more high better;

Just because of the existence in many technical barriers, industry prejudice, so current elevator has formed an overall industry prejudiceAs follows: the elevator of fixing model, only under fixed speed, operation is only safe; If according to the difference of mass carriedThe different speeds of service is set, and is unsafe;

The control method of a kind of elevator provided by the present invention, core object is just this as effect: capture many technology difficultiesInscribe, overcome industry prejudice; By formula 28-1 provided by the present invention, 2,3,4 formula analysis, accurately distinguishing electricityThe energy flow of ladder to operating mode (as ascending for elevator, descending, motoring condition, motor braking state etc.) again according to current fortuneCarry the safety value that calculates the speed of service that article quality m1 could be relatively accurate; When ascending for elevator/descending, basic calculatingStructure difference, the safety margins threshold values of the electric power of motoring condition is generally in power supply, motor driver, motor threeLittle power-handling capability, when motor braking state the safety margins threshold values of electric power be generally power supply, motor driver,Minimum License Value in electrification feedback braking power between motor, brakes and/or dynamic braking power, stateWhen different, the safety margins threshold values of each electric power may have significantly difference; As blind to operating mode in do not distinguished the energy flow of elevatorNot only object is carried out speed adjustment and do not had the effect that speed is adjusted, cause on the contrary elevator operation dangerous; Even at motorOn-position, if the too high ability to arrange jobs that easily causes braking power to exceed electric power system of speed, thus cause becomingFrequently in device busbar voltage raise/easily cause reporting fault/aircraft bombing.

In elevator field, lack open source literature for the damage research of elevator machine device; According to newton's 2 laws (F=m*a)Analyze with formula 1-2 provided by the invention (F1_cal=(m1+m0) * (g+aj)), the damage of mechanical device and speed/Power direct relation and little (speed fast/power can't cause wire cable rupture when large); The damage of mechanical deviceImmediate cause is to cross senior general at certain load-carrying brief acceleration to cause mechanical system stress to be greater than safe threshold values (as steel wire rope drawsPower is greater than breaking stress and ruptures, and causes power transmission shaft off-axis, gear explosion etc. as transfinite/shear stress of moment torque transfinites);When accelerating when up, maybe in the time that deceleration is descending, delivery article quality m1 value that can be current according to elevator according to formula 28-5Calculate rational acceleration and just can be convenient to avoid the comprehensive tensile force f 1 of steel wire rope to transfinite (even fracture); Descending when acceleratingTime, maybe, in the time that deceleration is up, must calculate according to the counterweight quality m3 value (but not m1 value) of elevator according to formula 28-6Go out rational acceleration and just can be convenient to avoid the comprehensive tensile force f 1 of steel wire rope to transfinite (even fracture);

Use control method and the system of a kind of elevator operating efficiency provided by the invention, the safety of elevator can be set accuratelyThe speed of service and/or acceleration, have important for the operational efficiency of raising elevator, the security performance of raising elevator operationEffect; Because current elevator has become infrastructure device in the modern life, in same building, quantity is identical, model is identicalElevator, as adopt this control method and system, can guarantee on safe basis, control efficiently elevator operation, be alsoAllow elevator operation sooner, more reasonable; Shorten passenger stand-by period, take the elevator time, reduce passenger service time,Use cost; As ensured under equal conveying capacity prerequisite, can reduce elevator safe, use number of units, frequency of utilization,Significantly reduce the consumption of institute's elevator to space resources, equipment funds resource, electric energy in building, be conducive to environmental protection and energy saving and fallConsumption.

Technical problem five:

Five of the technical problem to be solved in the present invention is to provide the method for supervising that a kind of parameters of elevator run transfinites, with at elevatorWhen operation, improve security;

The object of the invention is to be achieved through the following technical solutions:

The method for supervising (#3) that 39. the present invention also provide a kind of parameters of elevator run to transfinite, comprises step: obtain described electricityThe join operation value of driving source parameter of ladder, judges that the system whether described join operation value exceed described driving source parameter is pre-If value or safety margins threshold values; Described join operation value is to calculate gained based on elevator operation energy balance.

In this method for supervising (#3), whether transfinite for the driving source parameter of elevator under judging; This systemic presupposition valueLarge I is chosen according to the actual requirements, but conventionally meets: 0 < systemic presupposition value≤driving source parameter safety limiting threshold value.

Further, systemic presupposition value can also be set to multiple, transfinites with the parameter that realizes classification; As by steel wire ropeThe normal value of pulling force is as the first system preset value (supposing the safety margins threshold of the pulling force of its value 50% × steel wire rope);The safety margins threshold of the pulling force of 85% × steel wire rope is made as to second system preset value;

When the join operation value of the pulling force of steel wire rope > safety margins threshold, can start urgent speed limit, acceleration amplitude limit, shutdown,Forbid operation, send the safeguard measures such as alarm signal;

When safety margins threshold > the join operation value of the pulling force of steel wire rope > when second system preset value, now can send out a warning, withThe driving source of warning parameter is in second scope that transfinites;

When second system preset value > the join operation value of the pulling force of steel wire rope > when the first system preset value, now can be bright orangeLamp, with the driving source parameter of warning in first scope that transfinites;

In the time of join operation value < the first system preset value of the pulling force of steel wire rope, now can give a green light, to represent driving sourceParameter does not transfinite.

Comprehensive explanation:

The method for supervising of a kind of elevator provided by the present invention in the time that lifting moves and system (#1), a kind of elevator loadThe monitoring side that the control method of method for supervising and system (#2), a kind of elevator and system, a kind of parameters of elevator run transfiniteThe supervision method and system of method and system (#3), a kind of elevator, have the technical characterictic that part is identical between five, allThe acquisition methods of value and the core invention thought association of system in a kind of parameters of elevator run provided by the present invention: obtainGet the scheme of the join operation value of the measuring and calculating object of described elevator, join operation value be all based on elevator operation energy balanceCalculate gained, described elevator operation energy balance is calculated associated with elevator traffic direction;

But the function between five, application point are respectively had any different again;

Method for supervising and system (#1) when a kind of elevator lifting operation provided by the present invention, core concept is elevatorThe join operation value of measuring and calculating object and the comparison of reference data; In this reference data, the first reference value all requires to approach as far as possibleThe actual value of measuring and calculating object (as delivery article quality); The first reference value can much smaller than the safety margins threshold values of parameter (asThe maximum legal loading capacity of elevator); As taken elevator (supposing everyone heavy 75kg) as 4 people, normal weighing results should be 300kg,Once lift car is shown as 350kg or 250kg, can at once start safe handling mechanism; To realize (comprising personnelThe reason being snapped between car and elevator hoistways causes) elevator energy transmission monitors and early warning extremely, justIn the safety margins threshold values at elevator transfinite protection trigger before, there is more serious, uncertain security incident (bagThe personnel of drawing together are stuck, wire cable rupture, travelling gear explosion, motor driver aircraft bombing, elevator are out of control etc.) carry out beforeMonitoring and protection; Although elevator has safety tongs limit speed limit, the multiple ginsengs such as end protection, electric overcurrent, overvoltage protection of squattingThe safety margins threshold values protection of transfiniting of number, but elevator is once trigger various limit protections, elevator by enter the unknown, noControllable state; The transfinite effect of function of the limit threshold values of each parameter is difficult to test and conduct in the time that elevator normally movesSafeguard protection sensitivity is seriously on the low side, is essentially limit action afterwards; Suppose that safety tongs limit speed limit can normal stuck leadingRail, brings to a halt under its high speed suddenly, also will seriously frighten elevator passenger, easily cause pregnant woman, old passenger, child to hinderDie; Even prime of life passenger, if be snapped into the abnormal accident between car and the borehole wall, carries out the limit at safety tongsAlready may serious injures and deaths before speed limit.

This method for supervising and system (#1), conventionally can be in the time that elevator lifting moves real-time working;

The method for supervising of a kind of elevator load provided by the invention and system (#2), core concept is the load of elevatorJoin operation value and being compared to of safety margins threshold values of product quality set, for example, when delivery article quality is greater than 1.0 times of electricityThe maximum legal loading capacity of ladder (being assumed to be 14 people/1050kg) starts audio alert, reminds driver and conductor to reduce delivery peopleMember/article quality; Be that 4 people take elevator/normal weighing results and should be 300kg even actual, but weigh when weighing systemDuring for 1000kg, traditional apparatus for controlling elevator will think that the energy delivery system of elevator is working properly.

The method for supervising of this elevator load and system (#2), both can be certain particular moment (when operation as elevator zero-speed)Intermittent work, also can be in the time that elevator lifting moves continuously/monitor in real time work.

Analyze accordingly, provided by the invention the former (method for supervising and system (#1) when the operation of a kind of elevator lifting),Will be far above the latter (a kind of method for supervising of elevator load and system in security monitoring effect when elevator lifting operation(#2)), certainly, the latter can realize and weighing before the non-zero-speed operation of elevator, overload monitoring; Can play one for the formerNecessary supplementary function, still significant.
