Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
According to an embodiment of the application, a method for processing a fan in a condensing unit is provided. Alternatively, in the embodiment of the present application, the method for processing a fan in the condensing unit may be applied to a hardware environment formed by the terminal 101 and the server 102 as shown in fig. 1. As shown in fig. 1, the server 102 is connected to the terminal 101 through a network, which may be used to provide services (such as application services, etc.) to the terminal or clients installed on the terminal, and a database may be provided on the server or independent of the server, for providing data storage services to the server 102, where the network includes, but is not limited to: the terminal 101 is not limited to a PC, a mobile phone, a tablet computer, or the like.
The processing method of the fan in the condensing unit in the embodiment of the application may be executed by the server 102, may be executed by the terminal 101, or may be executed by both the server 102 and the terminal 101. The terminal 101 may execute the processing method of the fan in the condensing unit according to the embodiment of the present application, or may be executed by a client installed on the terminal.
Taking a terminal executing the method for processing a fan in a condensing unit according to an embodiment of the present application as an example, fig. 2 is a schematic flow chart of an alternative method for processing a fan in a condensing unit according to an embodiment of the present application, as shown in fig. 2, a flow of the method may include the following steps:
step 201, current operation data of a fan are obtained.
In some embodiments, the current operational data of the blower may be, but is not limited to, current to the motor of the blower, PWM duty cycle, or motor speed.
The current operation data can be obtained by detecting the electric signal of the fan through a circuit.
202, acquiring current detection data of the fan detected by a detection device under the condition that the fan runs according to the current running data, wherein the detection device comprises at least two detection pieces symmetrically arranged at an air outlet of the fan, and the detection pieces are used for detecting the rotation condition of the fan; .
In some embodiments, the data detected by the detecting device may be different under different operation data when the fan is operating normally. By acquiring the current detection data, the fault condition of the fan can be further judged.
The detection device may be of various types, for example, a wind sensor for detecting the wind power of a fan, a frequency detector for detecting the frequency of the blades of the fan, a pressure sensor for detecting the connection pressure between a motor bearing and the blades, and a temperature sensor for detecting the temperature at a predetermined position in front of the fan. And the infrared transceiver is used for detecting whether the fan blade moves or not.
Under the condition that the detection devices are different, the collected operation data of the fans are also different. For example, where the detection device is a wind sensor, the operational data may be a current of the wind turbine; in the case where the detection device is a frequency detector, the operation data may be a PWM duty cycle of the blower; in the case that the detection device is a pressure sensor, the operation data may be a rotational speed of the blower; in the case that the detection device is a temperature sensor, the operation data may be a rotational speed of the fan; in the case that the detection device is a distance detector, the operation data may be a rotational speed of the fan; in the case where the detection means is an infrared transceiver, the operational data may be the rotational speed of the fan.
It can be understood that if the fan blade falls off or the rotation speed of the motor is low, the fan blade does not rotate along with the rotation of the motor, and the distance detected by the distance detector does not change, so that the infrared transceiver can assist in detection.
Through setting up a plurality of detection pieces, every detection piece can all detect the fan, utilizes the testing result of a plurality of detection pieces to carry out fault judgement for the result is more accurate.
In an optional embodiment, before the obtaining the current detection data detected by the detecting device on the fan, the method further includes:
acquiring historical operation data of the fan under the condition of normal operation;
acquiring historical detection data of the fan detection by the detection device when the fan runs according to the historical running data;
and determining and storing a functional relation between the historical operation data and the historical detection data.
In some embodiments, by acquiring the historical operation data and the historical detection data and performing data analysis on the historical operation data and the historical detection data, for example, the historical operation data may be divided into a plurality of sections, and trend of the historical detection data corresponding to each section may be analyzed to obtain the functional relationship.
Taking operation data as motor current and detection data as wind power data as an example, on one hand, the wind power data and the motor current can be collected through experiments to find a corresponding functional relation, so that a data model is built; on the other hand, the section correspondence of the section of the wind power data collected by the experiment and the motor current data can be carried out, and a data model is built. The larger the wind power is, the larger the data of the obtained wind sensor is, the larger the motor current is, and the two have a set upper limit value, and the positive correlation function relation is formed.
Taking operation data as PWM duty cycle and detection data as fan blade frequency as examples, on one hand, the data of the fan blade frequency and the motor frequency can be collected through experiments, and the functional relation between the fan blade frequency and the PWM duty cycle is found by combining the functional relation between the motor frequency and the PWM duty cycle of a motor specification, so that a data model is built; on the other hand, the interval of segmenting the fan blade frequency collected by the experiment and the PWM duty ratio under the corresponding motor frequency corresponds to each other, and a data model is built. The speed regulating voltage and the PWM duty ratio of the motor are in a positive correlation linear function relationship (can be obtained through a correlation specification), the speed regulating voltage and the motor frequency are in a positive correlation linear function relationship, the fan blade function and the motor frequency are in a positive correlation linear function relationship (the fan blade frequency is increased along with the increase of the motor frequency), and therefore the positive correlation linear function relationship between the frequency detector data (the fan blade frequency) and the PWM duty ratio can be obtained according to the mode.
Step 203, determining normal detection data of the detection device corresponding to the current operation data under the condition that the fan operates normally.
In some embodiments, the fan detects the fan under the condition of normal operation, and stores detected data, or performs data analysis on the obtained detected data to obtain a functional relationship between the operation data and the detected data, so that normal detected data corresponding to the current operation data can be determined from the stored data, or the normal detected data corresponding to the current operation data can be obtained by using the functional relationship.
Specifically, the current operation data may be input into the functional relationship, and the normal detection data may be calculated.
And 204, comparing each piece of current detection data with the normal detection data to obtain respective comparison results.
In some embodiments, a plurality of detecting elements are configured in the detecting device, each piece of current detecting data is compared with the normal detecting data, and whether the current detecting data is within a preset range of the normal detecting data is judged.
And 205, determining the fault condition of the fan based on the comparison result.
In some embodiments, the number of the detecting elements is plural, so that the fan fault condition can be comprehensively judged through the comparison results of the plurality of detecting elements.
In an alternative embodiment, determining a fault condition of the fan based on the comparison result includes:
determining that the fault condition is fault-free under the condition that the number of the current detection data in the normal detection data preset range is smaller than a first preset value;
and under the condition that the number of the current detection data in the normal detection data preset range is not smaller than a first preset value, determining that the fault condition is a fault.
In some embodiments, the first preset value may be set based on practical situations, and is generally set to a value less than half the number of the detecting elements.
In an optional embodiment, in a case that the types of the detection devices are multiple, after determining the fault condition of the fan based on the comparison result, the method further includes:
and if the fault conditions corresponding to the detection devices of each type are inconsistent, alarming and detecting the running state of the condensing unit.
In some embodiments, various detection devices may be provided to detect the fan, so as to improve detection accuracy. When the fault conditions obtained after detection by the detection device are inconsistent, the alarm can be given to inform a technician to check and overhaul in time, and the running state of the condensing unit can be detected to judge whether the condensing unit runs abnormally or not.
In an optional embodiment, the condensing unit includes at least one fan, and after determining the fault condition of the fan based on the comparison result, the method further includes:
determining the number of fans with fault conditions as faults;
obtaining the total number of fans;
stopping the condensing unit under the condition that the number of fans is larger than a second preset value, wherein the second preset value does not exceed the total number;
and under the condition that the number of the failed fans is not greater than a second preset value, controlling the failed fans to be closed, and controlling the fans which are not failed to increase the rotating speed.
In some embodiments, when it is determined that the fan fails, the failed fan may be controlled to shut down, so as to avoid the failed fan from continuing to operate, which results in a failure of the condensing unit. Through judging the quantity of fault fans, under the condition that the quantity of fault fans is more and exceeds a second preset value, the condensing unit is stopped, so that technicians can overhaul the fans in time. When the number of the fault fans is smaller, the fault fans can be closed first, so that the cooling requirement is guaranteed, the rotating speed of the fans which are not faulty can be increased, and the air quantity of the fans before and after control is unchanged.
In a specific embodiment, in the method for processing a fan in a condensing unit, referring to fig. 3, two symmetrical wind sensors can be installed at an air outlet of the fan, wind force judgment is performed by using the two wind sensors, a data model of wind force data and motor current is built, and a main control can set a fault range value through the data model, so that relevant detection is realized. Or, symmetrical frequency detectors can be arranged at the air outlet of the fan, the frequency detectors are utilized to detect the fan blade frequency, a data model of frequency data and PWM duty ratio is built, and the main control can set a fault range value through the data model, so that relevant detection is realized.
Or referring to fig. 4, two distance detectors are installed at the center circle of the fan blade, two distance detectors are installed at the right rear part correspondingly, data of four distance detectors under different motor speeds are detected through experiments, and a data model of distance values and speeds is built. Taking the three-blade fan in fig. 4 as an example, a transmitter is assembled in front of the three-blade fan, a receiver is assembled at the rear of the three-blade fan, and an infrared transceiver is respectively installed at the spare positions of the three-blade fan (i.e. the number of the infrared transceivers is formulated according to the number of the blades and the infrared transceivers are installed at equal distances), so that the detection can still be performed when the fan stops at any position or rotates slowly. And (3) collecting data of the distance data and the motor rotating speed through experiments, searching a corresponding functional relation (for example, in the process of rotating speed from low to high, the front distance detector data gradually decreases, the rear distance detector data gradually increases, the front and rear detector distance data fluctuates in a small range of intervals along with the stable running of the motor, and in different rotating speeds, the front detector distance data and the motor rotate to form a negative correlation functional relation, and the rear detector distance data and the motor rotate to form a positive correlation functional relation), so that a data model is built. On the other hand, the interval correspondence of segmenting is carried out on the distance data of the front detector and the rear detector collected through experiments and the data of the motor rotating speed, and a data model is built.
Referring to fig. 5, the process of establishing the data model may be to acquire the detection data of the detection device, acquire the operation data corresponding to the detection data obtained according to the characteristic relationship and the experimental calibration, build a data model of the detection data and the operation data, and analyze the fault condition of the motor and the fan blade according to the built data model.
Through carrying out the fault detection that the fan blade does not follow the motor to rotate, after detecting the fault that the fan blade does not follow the motor to rotate, fan control of a single fan unit, a double fan and more than the single fan unit is carried out.
Under the condition that the running signal of the motor is normal based on the main control, the fan blade is guaranteed to not follow the motor to rotate under the normal running of the motor. Before entering the refrigeration mode, the operation of the fan is not stabilized, and in order to avoid misjudgment, the main control does not judge the returned signal of the wind sensor.
Specifically, taking the detection device as two wind sensors as an example, referring to fig. 6, after the system is in a cold mode, the main control part compares signals transmitted by the two wind sensors, if the signals meet a fault preset value (namely a fault signal) set in a data model constructed by a wind power value and a current value, a fault alarm that the fan blades do not rotate along with the motor is carried out, and then fan control under the fault is carried out; if one of the sensors meets the fault preset value and the other signal does not meet the fault preset value (namely a normal signal), comparing the signals returned by the two sensors for a plurality of times (for example, ten times), and if the signals are similar signals, returning to the judgment of the fault signal; if the different signals are still kept, judging that the sensor is faulty, and checking whether the sensor is damaged or falls off or the like on site. And under the normal operation of the motor (namely no motor fault alarm), after entering a refrigeration mode, the main control judges the signals of the two wind sensors.
Referring to fig. 7, when the unit is a single fan, the main control firstly judges the sensor signals on the basis of the signals, carries out data acquisition on the wind sensors, judges whether the acquired wind power data meets a fault preset value, if not, normally samples the signals, and if yes, simultaneously controls the motor to stop running according to a motor control method (as shown in fig. 8) when the fan blades do not rotate along with the motor to fault, and carries out shutdown treatment and fault alarm because of the single fan unit; if the failure preset value is not met, signal sampling is normally carried out.
Referring to fig. 8, the motor control method when the fan blade does not follow the motor rotation fault specifically includes: judging whether the condensing unit is a single fan or not after determining that the fan blades do not follow the rotation fault of the motor, if so, stopping the fan, and performing fault alarm; if the fan is not a single fan, judging whether a plurality of fans have faults, if not, stopping the operation of the faulty fan, controlling other fans to maintain operation and increase the rotating speed, if so, stopping the machine, and giving a fault alarm.
When the unit is provided with two fans and more than two fans, as shown in fig. 9, the main control judges the signals of the two wind sensors of each fan, if the two sensors of some fans meet the fault preset value, the main control gives an alarm on the corresponding fans, and simultaneously controls the corresponding motors to stop running, and other motors without faults normally run according to the motor control method (as shown in fig. 8) when the fan blades do not follow the motor to rotate and fail; if the failure preset value is not met, signal sampling is normally carried out.
The frequency detector is similar to the wind sensor in terms of judgment, and will not be described in detail here.
Under the condition that the detection device is a distance detector and an infrared transceiver, the infrared transceiver can ensure that the fault detection is carried out when the fan blade stops or slowly rotates without normally following the rotation of the motor (namely, the infrared transceiver is used for detecting the fan blade in the range that the value of the distance detection possibly cannot meet the fault set value when the fan blade stops or slowly rotates without normally following the rotation of the motor), and the auxiliary detection is carried out on the distance detector. In addition, according to the arrangement of the infrared transceivers, part of the infrared transceivers can detect the blades, and the rest can not detect the blades, so that the working state of the fan blades can be judged.
For example, if the distance detection data meets the fault set value, no matter whether the infrared transceiver detects that the fault state is met, the unit fault alarms, and when the third-point fan blade of the implementation mode does not follow the motor rotation fault, the motor control method and the fourth-point single fan, the double fans and the unit fan blades above do not follow the motor rotation fault detection to process;
if the pressure data does not meet the fault set value, the infrared transceiver detects the condition of meeting the fault, and at the moment, the unit is in a state of needing normal operation of the motor, alarm processing is carried out, the unit is in fault alarm, and when the fan blades do not rotate along with the motor, the motor control method, the single fan, the double fans and the unit fan blades above do not rotate along with the motor to detect the fault, and the unit state is checked.
Further, when the failure results obtained by the wind sensor, the frequency detector, the distance detector and the like are inconsistent, alarm processing is performed, the state of the unit is checked, and whether the sensor or the frequency detector fails or not is verified.
The application provides a processing method of fan in condensing unit solves if fan motor and flabellum are connected inadequately, or unexpected interface loosens, leads to motor normal operating, and the flabellum does not follow pivoted condition or can't reach the requirement rotational speed, can detect fast and send out fault alarm, guarantees to maintain fast, avoids appearing other damages of unit and use loss of property.
Based on the same conception, the embodiment of the present application provides a processing device for a fan in a condensing unit, and the specific implementation of the device may be referred to the description of the embodiment of the method, and the repetition is omitted, as shown in fig. 10, where the device mainly includes:
