Detailed Description
Embodiments of the present invention will be described in detail below, by way of example with reference to the accompanying drawings.
With the development of the technology of the permanent magnet synchronous motor, the air conditioner also gradually adopts the permanent magnet synchronous motor, meanwhile, with the pursuit of people on living standards, the air conditioner is also installed in various environments, which means that the working condition of the motor in the air conditioner needs to be considered is more and more severe, and the requirements on all aspects are also higher.
In the related art, for fault control of a motor, a controller eliminates faults by controlling the motor to stop working, automatically resumes working after a certain time, and solves problems by prompting manual repair after the accumulated number of faults reaches a certain value in a certain time, but for repeated motor faults caused by abnormal internal storage of a chip due to strong external interference of the controller such as high voltage surge higher than 6000V or lightning stroke, the adoption of the mode cannot be effectively solved.
In order to solve the above problems, an embodiment of a first aspect of the present invention provides a motor control method, by which normal operation of a motor can be quickly recovered under the condition that a controller is subjected to abnormal interference failure, and manual intervention is not required, so that user experience is improved.
A motor control method according to an embodiment of the present invention is described below with reference to fig. 1, and as shown in fig. 1, the motor control method includes at least steps S1 to S4.
Step S1, acquiring working state information of a motor.
The working state information may be understood as information reflecting the working condition of the motor, such as information of the working temperature of the motor, the working frequency of the motor, or the rotation speed of the motor.
And S2, determining abnormal operation of the motor according to the working state information.
The abnormal motor operation refers to driving faults of the motor, and at least comprises abnormal interference faults and real faults. The abnormal interference fault can be understood as a fault generated by the occurrence of an abnormality of the motor driving parameter, for example, the abnormal interference fault can be an abnormal interference such as lightning stroke or surge and the like of a controller for controlling the motor, so that the motor driving parameter is interfered to be abnormal, and when the motor is driven, the motor is repeatedly failed due to the abnormal driving parameter; the real fault may be understood as a fault generated by an operation fault of the motor itself or an operation fault of the controller, for example, the real fault may include a motor stall, a motor capacitor open circuit, a motor capacitor short circuit, a motor turn-to-turn short circuit, a motor thermal protector failure, and the like.
Specifically, the fault judgment condition of the motor can be preset according to the working state information, in practical application, the working state information is judged based on the stored fault judgment condition through the working state information acquired in real time, and if the working state information meets the fault judgment condition, the abnormal operation of the motor can be determined.
And step S3, determining the type of abnormal operation of the motor.
In the embodiment, types of motor operation anomalies such as motor stalling, motor capacitor open circuit, motor capacitor short circuit, motor turn-to-turn short circuit, motor thermal protector failure, controller failure, motor driving parameter anomaly and the like may be classified according to a certain rule in advance and stored, for example, the types of motor operation anomalies such as motor stalling, motor capacitor open circuit, motor capacitor short circuit, motor turn-to-turn short circuit, motor thermal protector failure, controller failure, motor driving parameter anomaly and the like may occur in actual motor application, and the types of each motor operation anomaly are numbered and stored.
And S4, determining that the motor continuously generates the same type of abnormality for N times and the software reset mark is not detected, and controlling the motor to reset the software.
Wherein, N is more than 1, preferably, the value range of N is 3-5, under this scope, not only is convenient for accurately judge the reason of motor operation abnormality, but also can guarantee the duration that can resume automatically when the motor operation is abnormal, avoid influencing the problem that the user uses because of repeated trouble makes the time overlength.
Specifically, since the controller controlling the motor is disturbed by an abnormal disturbance such as a lightning stroke or a surge, the motor driving parameters are disturbed abnormally, thereby, when the motor is driven, the repeated motor faults generated by the abnormal driving parameters, that is, the motor is repeatedly abnormal, when the motor is in operation and is identical in each abnormality, the reason for the abnormal motor operation is described as the reason that the controller is disturbed by the abnormal abnormality, but in fact, the motor itself is not abnormal, in this case, if the motor is still in fault, the operation of clearing the fault and restarting is repeatedly executed, or a plurality of faults occur within a certain time, the mode of locking and alarming the fault is not effectively solved, and the motor is easy to cause the failure to automatically recover, if the motor is not in manual intervention, the normal operation is not affected, in this case, the motor is not continuously in operation, in the case, the abnormal operation is not controlled, in the abnormal operation is considered to be in the abnormal state, in consideration of recovering the normal operation by the reset operation, in the reset operation, that the abnormal operation is not in the reset operation is performed, the abnormal operation is not in the case of the abnormal operation is performed, the motor is continuously in the same time as the abnormal operation is controlled, the abnormal operation is not in the abnormal operation is performed, the abnormal operation is not in the normal state, the normal operation is continuously reset is controlled, when the abnormal operation is performed, and the abnormal operation is not is continuously reset is performed, in the abnormal operation is not is controlled in the normal operation is performed, the abnormal data interfered in the controller can be recovered by controlling the motor to reset the software, normal operation of the motor is recovered, manual intervention is not needed, labor cost is reduced, time cost is saved, and user experience is improved.
According to the motor control method provided by the embodiment of the invention, when the motor operation is determined to be abnormal, if the motor is determined to continuously generate the same type of abnormality for N times, the controller for controlling the motor is subjected to external abnormal interference, so that the motor driving parameters are interfered to be abnormal, the motor repeatedly generates the same type of faults, in this case, the software reset mark is not detected at the same time, the control motor can restore the interfered abnormal data in the controller by performing software reset, the normal operation of the motor is restored, the manual intervention is not needed, the labor cost is reduced, and the user experience is improved.
In some embodiments, if it is determined that the same type of abnormality occurs to the motor N times continuously and the software reset flag is detected and the abnormality occurring to the motor N times continuously is different from the abnormality occurring before the reset, it is indicated that the controller has performed the reset operation, and the abnormality occurring to the motor before the reset is different from the abnormality occurring to the motor of the same type occurring N times continuously after the reset, it is indicated that the abnormality occurring to the motor N times continuously after the reset is caused by the controller being subjected to the external abnormality, so that the motor is controlled to perform the software reset to automatically recover the abnormal data interfered in the controller, thereby recovering the normal operation of the motor without the manual intervention, reducing the labor cost, saving the time cost, and improving the user experience.
In some embodiments, if it is determined that the same type of abnormality occurs to the motor N times continuously and the software reset flag is detected, and the abnormality occurring to the motor N times continuously is the same as the type of abnormality occurring before the reset, it is indicated that the controller has performed the over-reset operation, and the abnormality occurring to the motor before the reset is the same as the abnormality occurring to the motor of the same type occurring to N times continuously after the reset, it is indicated that the abnormality occurring to the motor of the same type occurring to N times continuously is caused by the real fault of the motor after the reset, so that the fault of the motor can be determined and the fault alarm can be performed, so that after-sales personnel can quickly locate the cause of the fault and maintain in time.
In some embodiments, if it is determined that the motor continuously generates N anomalies and the anomaly types are different, and M anomalies continuously generate within the first preset time and the software reset flag is not detected, it indicates that the number of running anomalies of the motor accumulated within the first preset time reaches a certain value, and the types of the anomalies are different each time, and the controller does not perform the reset operation, then controls the motor to perform the software reset to clear the fault through the reset operation.
Wherein M >1, preferably, the value range of M is 5-10, under this scope, not only is convenient for accurately judge the reason that the motor is abnormal in operation, but also can guarantee the duration that can resume automatically when the motor is abnormal in operation, avoid influencing the problem that the user uses because of repeated trouble makes the time overlength.
In some embodiments, if it is determined that the motor continuously generates N anomalies and the anomaly types are different, and M anomalies occur in the first preset time and the software reset flag is detected, it is indicated that the number of running anomalies of the motor accumulated in the first preset time reaches a certain value, and the types of running anomalies are also different each time, and the controller has performed an over-reset operation, and after the controller is reset, the running anomalies of the motor are not resolved, so that a motor fault can be determined and a fault alarm can be performed, so that after-sales personnel can quickly locate the cause of the fault and maintain the fault in time.
In some embodiments, if it is determined that the motor continuously experiences N anomalies and the anomaly types are different and the number of anomalies occurring within the first preset time is less than M, the current anomaly information is stored and the current motor fault state is cleared.
Specifically, when the number of motor operation anomalies accumulated in the first preset time does not reach a certain value, the controller does not perform fault locking and alarm, but stores current anomaly information to a designated position, for example, the current anomaly information is stored to a target address of an EPROM (Erasable Programmable Read Only Memory, erasable programmable read-only register) of the controller, and the EPROM supports long-term storage, so that subsequent calling and use can be facilitated. Further, after the first time T1s, the controller clears the current motor fault state, which can be understood that the current motor fault state refers to the fault state stored after the abnormal operation of the motor, and the current motor fault state is different from the storage position of the current abnormal information, the current abnormal information is stored in the EPROM of the controller, and the current motor fault state is stored in the ROM (Read-Only Memory) of the controller, when the motor is restarted, if the current motor fault state is still stored in the ROM, the controller defaults to the motor fault and cannot operate normally, and therefore, the controller can clear the current motor fault state stored in the ROM to ensure that the motor can operate normally when the motor is restarted.
In some embodiments, prior to controlling the motor to perform the software reset, current exception information is also stored, and a software reset flag is set and stored for subsequent retrieval and use.
In some embodiments, if the motor is determined to be running normally and the continuous running time reaches the second preset time according to the working state information, the motor is indicated to be recovered to normal working, so that the software reset flag and the abnormal information can be cleared.
The motor control method according to the embodiment of the present invention is illustrated with reference to fig. 2, and specific steps are as follows.
And S5, judging whether the motor runs abnormally or not. If the motor is abnormal, executing a step S6; if the motor is operating normally, step S12 is performed.
And S6, judging whether the abnormality of the motor continuously occurs for N times is of the same type. If yes, executing step S7; if not, step S14 is performed.
Step S7, judging whether the software reset mark is reset or not, namely judging whether the software reset mark is detected or not. If yes, executing step S8; if not, step S10 is performed.
And S8, judging whether the abnormality of the motor continuously occurs for N times is the same as the abnormality type occurring before resetting. If yes, executing step S9; if not, step S10 is performed.
And S9, fault locking and alarming.
Step S10, storing current abnormal information, setting a software reset mark and storing.
Step S11, executing software reset.
Step S12, judging whether the continuous running time of the motor reaches a second preset time T2 minutes. If yes, executing step S13; if not, the step S12 is continued.
Step S13, clearing the software reset mark and the abnormal information.
Step S14, judging whether M times of abnormality continuously occur in the first preset time T1. If yes, executing step S15; if not, step S19 is performed.
Step S15, judging whether the software reset mark is reset or not, namely judging whether the software reset mark is detected or not. If yes, go to step S16; if not, step S17 is performed.
And S16, fault locking and alarming.
And S17, storing current abnormal information, setting a software reset mark and storing.
Step S18, executing software reset.
And S19, storing current abnormal information, and clearing the current motor fault state after T1S.
In summary, according to the motor control method provided by the embodiment of the invention, through the steps, whether the motor operation abnormality is caused by abnormal interference or is truly fault can be effectively identified, and under the condition of abnormal interference fault, the interfered abnormal storage content can be recovered by executing software reset, so that the abnormality can be quickly repaired under the condition of no human intervention, the labor cost is reduced, the user experience is improved, and the fault can be quickly locked when the motor is truly fault, thereby facilitating the subsequent maintenance.
