[0068] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0069] The motor, as a driving device, is often installed in the roof, wall, inside and outside, etc. which are not easy to maintain, as an important part of air conditioner and ventilation system. Usually, the motor controller is filled with gel and firmly installed with the motor structure for heat dissipation, and only the communication line is led out from the controller, and the power supply and control bundle are led out through the structure reserved hole, which is used to feed back the motor running information to the air conditioner mainboard or other control board.

[0070] When the system malfunctions and the motor is the only component to be checked for abnormalities, maintenance personnel need to use maintenance tools to carefully inspect the motor, and the fault location is difficult.

[0071] Therefore, how to diagnose the motor has become an urgent problem to be solved.

[0072] Based on this, this application provides a motor diagnostic method, applied to motor diagnostic equipment in a motor diagnostic system, such as... Figure 1 As shown, the motor diagnostic system includes a motor device, a motor diagnostic device, and electronic equipment. The motor device and the motor diagnostic device are communicatively connected, and the motor diagnostic device and the electronic equipment are communicatively connected.

[0073] Specifically, such as Figure 2 As shown, the motor device includes a motor controller. The electronic device can be a terminal device, such as a mobile phone, computer, tablet computer, etc. The embodiments in this application do not specifically limit the electronic device.

[0074] Optionally, the motor controller of the motor equipment has reserved control wiring harnesses and communication lines, etc. The motor diagnostic equipment can be connected to the motor controller of the motor equipment via the communication line, and electronic devices can be connected to the motor diagnostic equipment wirelessly via Bluetooth or WIFI. The motor diagnostic equipment may also include a rechargeable battery to provide power to the motor diagnostic equipment.

[0075] The communication line can be a communication method with strong anti-interference capabilities, such as RS485, RS422, or CAN communication.

[0076] RS-485 stands for "Recommended Standard 485." It is a serial communication standard that uses differential signal transmission, offering strong anti-interference capabilities and enabling long-distance, multi-point communication. RS-422 also stands for "Recommended Standard 422." While also a serial communication interface standard using differential signal transmission, RS-422 is full-duplex, unlike RS-485 which is half-duplex. CAN stands for "Controller Area Network." It is a serial communication network that effectively supports distributed or real-time control, featuring high performance and high reliability, and is widely used in automotive electronics, industrial automation, and other fields.

[0077] The connection mode of the motor diagnosis device and the electronic device can be any wireless mode such as NFC, lora, infrared, etc., or a wired mode such as USB. Among them, NFC is the full name of "Near Field Communication", which means "near field communication" in Chinese. It is a short-range high-frequency wireless communication technology that allows electronic devices to exchange data in a non-contact point-to-point data transmission (within ten centimeters). LoRa is the full name of "Long Range", which means "long distance" in Chinese. LoRa is a low-power wide-area network communication technology with long transmission distance and low power consumption, suitable for application scenarios in the Internet of Things field with high requirements for distance and power consumption.

[0078] Specifically, the motor diagnosis device receives the running data corresponding to the motor device and the initial fault identifier sent by the motor device, analyzes the initial fault identifier, determines the target fault description information corresponding to the motor device, ensures the accuracy of the determined target fault description information corresponding to the motor device, and realizes the diagnosis of the motor. Then, the target fault description information and the running data are transmitted to the electronic device to make the electronic device display the target fault description information and the running data, so that the maintenance personnel can locate the motor fault position according to the target fault description information and the running data. The efficiency of diagnosing the motor is improved. In addition, the above method solves the problems of high maintenance cost, low efficiency and inability to perform post-sales of the motor device.

[0079] According to the embodiment of the present application, a motor diagnosis method embodiment is provided. It should be noted that the steps shown in the flowchart of the drawing can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from here.

[0080] In this embodiment, a motor diagnosis method is provided, which can be used in the motor diagnosis device of the above-mentioned motor diagnosis system. The motor diagnosis system includes a motor device, a motor diagnosis device and an electronic device, the motor device and the motor diagnosis device are in communication connection, Figure 3 The flowchart of the motor diagnosis method according to the embodiment of the present application is shown in Figure 3 The flowchart includes the following steps:

[0081] Step S101, receiving the running data corresponding to the motor device and the initial fault identifier sent by the motor device.

[0082] Specifically, the motor diagnosis device can periodically send request information for reading running data and initial fault identifier to the motor controller in the motor device based on the communication connection between the motor controller in the motor device.

[0083] The motor controller in the motor equipment sends the running data and the initial fault identification corresponding to the motor equipment to the motor diagnostic equipment after receiving the request information of reading the running data and the initial fault identification sent by the motor diagnostic equipment.

[0084] It should be noted that the initial fault identification can be obtained by the motor controller based on the running data of the motor equipment.

[0085] The running data can include DC bus voltage, actual speed and other running data.

[0086] For example, as shown in Table 1, the communication data between the motor diagnostic equipment and the motor equipment.

[0087] Table 1 Communication data between motor diagnostic equipment and motor equipment

[0088]

[0089] Wherein, DATA can be an initial fault identification, and the feedback DATA data is 2 bytes.

[0090] Step S102, analyzing the initial fault identification to determine the target fault description information corresponding to the motor equipment.

[0091] Specifically, after receiving the initial fault identification, the motor diagnostic equipment can analyze the initial fault identification according to the corresponding relationship between the fault identification and the fault description information, and determine the target fault description information corresponding to the motor equipment.

[0092] For example, the corresponding relationship between the fault identification and the fault information can be as shown in Table 2.

[0093] Table 2 Corresponding relationship table between fault identification and fault information

[0094] NO. Fault identification Fault description information 1 0x0000 No fault 2 0x0001 Over-temperature protection 3 0x0002 Three-phase power supply open-phase 4 0x0004 Over-current protection 5 0x0008 Motor start-up locked-rotor protection 6 0x0010 Output open-phase fault 7 0x0020 Under-voltage fault 8 0x0040 Over-voltage fault

[0095] Optionally, the target fault description information supports superposition. That is, if the motor controller simultaneously appears over-temperature protection fault and over-current protection fault, the motor controller feedback initial fault identification is 0x0001+0x0004 equals 0x0005. After the after-sales personnel solve the over-current protection fault problem on site, the motor controller will automatically clear the initial fault identification 0x0001 corresponding to the over-temperature protection fault, and keep the initial fault identification 0x0004 of the over-current protection fault.

[0096] Step S103, transmitting the target fault description information and the running data to the electronic equipment, so that the electronic equipment displays the target fault description information and the running data.

The electronic device displays the target fault description information and the running data.

[0098] In an alternative embodiment of the present application, the motor diagnosis device can also choose to store the motor feedback data directly in the SD card and display the target fault description information and the running data by using the nixie tube.

[0099] In an alternative embodiment of the present application, the motor diagnosis device can store the target fault description information and the running data in the storage space, and then display the target fault description information and the running data based on the nixie tube.

Then, the target fault description information and the running data are displayed, so that maintenance personnel can locate the motor fault position according to the target fault description information and the running data. The efficiency of diagnosing the motor is improved. In addition, the above method solves the problems of high maintenance cost, low efficiency, and inability to perform post-sales of the motor device.

[0107] Specifically, the motor diagnosis device can input the operation data to the preset fault identification model, and determine the candidate fault identification corresponding to the motor device based on the preset fault identification model.

[0108] The preset fault identification model can be any one of a radial basis function (RBF) network, a feedforward neural network (FFNN), a convolutional neural network (CNN), a deconvolutional network (DN), a deep convolutional inverse graphics network (DCIGN), a generative adversarial network (GAN), a recurrent neural network (RNN), a long / short term memory (LSTM), a deep residual network (DRN), and an extreme learning machine (ELM). The preset fault identification model is not limited in the embodiments of the present application.

[0109] The preset fault identification model can be generated based on preset training data. The preset training data includes training operation data corresponding to the motor device and training fault identification corresponding to the training operation data.

[0116] Step a2, if the initial fault identifier is inconsistent with the candidate fault identifier, first fault description information corresponding to the initial fault identifier and second fault description information corresponding to the candidate fault identifier are determined according to the correspondence between the fault identifier and the fault description information.

[0117] Specifically, if the initial fault identifier is inconsistent with the candidate fault identifier, the motor diagnostic device determines first fault description information corresponding to the initial fault identifier and second fault description information corresponding to the candidate fault identifier according to the correspondence between the fault identifier and the fault description information.

[0118] Step a3, the first fault description information and the second fault description information are integrated to generate target fault description information.

[0119] Specifically, the motor diagnostic device can integrate the first fault description information and the second fault description information to generate target fault description information.

[0120] Step S203, the target fault description information and the operation data are displayed.

[0121] For this step, please refer to the description of step S103 above, which will not be repeated here.

[0130] In step S304, if the target fault description information is that the program in the motor device is not updated, the program update file sent by the electronic device is received.

[0131] The program update file is used for updating the current program in the motor device.

[0132] Specifically, if the target fault description information is that the program in the motor device is not updated, the electronic device can receive the program update file input by the user, or receive the program update file sent by other devices. After receiving the program update file, the electronic device can send the program update file to the motor diagnosis device according to the Ymodem protocol based on the communication connection between the motor diagnosis device and the electronic device, so that the motor diagnosis device can receive the program update file sent by the electronic device.

[0140] Specifically, the motor diagnostic device can send the target check value to the electronic device. The electronic device can compare the target check value with an initial check value corresponding to the program update file to generate check result information. Specifically, if the target check value is consistent with the initial check value, the check result information indicates that the program update file is checked successfully; if the target check value is inconsistent with the initial check value, the check result information indicates that the program update file is not checked successfully.

[0141] In step S3053, the check result information sent by the electronic device is received.

[0142] Specifically, the motor diagnostic device can receive the check result information sent by the electronic device.

[0143] In step S3054, it is determined whether the program update file is checked successfully according to the check result information.

[0144] Specifically, the motor diagnostic device identifies the check result information. If the check result information indicates that the target check value is consistent with the initial check value, it is determined that the program update file is checked successfully; if the check result information indicates that the target check value is inconsistent with the initial check value, it is determined that the program update file is not checked successfully.

[0145] In step S306, if the program update file is checked successfully, the program update file is transmitted to the motor device based on a communication connection between the motor devices.

[0146] Specifically, if the program update file is successfully verified, the motor diagnostic device transmits the program update file to the Flash space of the motor controller of the motor device based on the wired communication interface between the motor diagnostic device and the motor device.

[0147] Step S307, if the program update file is not successfully verified, the motor diagnostic device receives the program update file sent by the electronic device again.

[0148] Specifically, if the program update file is not successfully verified, the motor diagnostic device receives the program update file sent by the electronic device again.

[0149] In another alternative embodiment of the present application, if the target fault description information is that the program in the motor device is not updated, the motor diagnostic device receives the program update file sent by the electronic device. After receiving the program update file sent by the electronic device, the motor diagnostic device can transmit the program update file transmitted by the electronic device to the motor device in a transparent manner. After receiving the program update file, the motor device verifies the program update file based on a preset verification method to generate a target verification value. Then, the motor device sends the target verification value to the electronic device through the motor diagnostic device, so that the electronic device compares the target verification value with an initial verification value corresponding to the program update file to generate verification information. According to the verification result information, it is judged whether the program update file is successfully verified. If the program update file is not successfully verified, the motor diagnostic device receives the program update file sent by the electronic device again.

[0150] Step S308, receiving a user instruction.

[0151] Specifically, the motor diagnostic device can receive a user instruction.

[0152] Step S309, reading a target program file stored in a storage device corresponding to the motor diagnostic device based on the user instruction.

[0153] In an alternative embodiment, after receiving the user instruction, the motor diagnostic device can read a target program file stored in a storage device corresponding to the motor diagnostic device. The storage device is pluggably connected to the motor diagnostic device.

[0154] For example, after receiving the user instruction, the motor diagnostic device can read a target program file stored in an SD card corresponding to the motor diagnostic device based on the SD card reading function of the motor diagnostic device.

[0155] Step S310, transmitting the target program file to the motor device.

[0156] Specifically, the motor diagnostic device transmits the target program file to the motor device.

[0157] For example, when the electromagnetic interference in the industrial field is serious, the quality of wireless signal transmission is poor. Figure 2 As shown in FIG. 6, the motor diagnosis device is provided with an SD card reading function. The SD card storing the target program file is inserted into the card slot of the motor diagnosis device. The motor diagnosis device program update button is pressed. The target program file transmission link is shielded and transmitted into the motor controller of the motor device in a wired manner with better performance. The motor device can verify the target program file. After the verification is passed, the indicator light prompts that the program upgrade is completed.

[0158] The motor diagnosis method provided by the embodiment of the present application can receive the program update file sent by the electronic device, verify the program update file based on the preset verification method, generate a target verification value, and ensure the accuracy of the generated target verification value. The target verification value is sent to the electronic device to compare the target verification value with the initial verification value corresponding to the program update file to generate verification result information. The electronic device sends the verification result information. According to the verification result information, it is judged whether the program update file is verified successfully, and the accuracy of the result of whether the obtained program update file is verified successfully is ensured.

[0159] If the program update file is verified successfully, the program update file is transmitted to the motor device based on the communication connection between the motor devices, ensuring the accuracy of the program update file transmitted to the motor device, so that the motor device can update the current program based on the program update file, and further solve the fault of the motor device, ensuring the normal work of the electronic device. The problem that the chip programming port is covered by glue when the new and old motor needs to be optimized and upgraded in the prior art is solved. If the program update file is not verified successfully, the program update file sent by the electronic device is received again, avoiding the inaccuracy of the program update file transmitted to the motor device, thereby affecting the normal work of the motor device.

[0160] In addition, the motor diagnosis device can also receive user instructions; based on the user instructions, the target program file stored in the storage device corresponding to the motor diagnosis device is read, ensuring the accuracy of the read target program file. The target program file is transmitted to the motor device. Thus, the motor device can receive the target program file. The problem that the 4G / 5G signal coverage strength is low in the industrial field, or the electromagnetic interference in the field is serious, and the wireless signal transmission is unstable, and the success rate of uploading and downloading data by using the cloud server is low in the prior art is solved.

[0161] In an alternative embodiment of the present application, in order to better introduce the motor diagnosis method provided by the embodiment of the present application, a specific implementation is provided.

[0162] Exemplary, taking DM series motor as an example, the communication line is mainly RT communication line (simplex). The diagnostic controller of the motor diagnostic device adopts serial port idle interruption and uses two serial ports to pass through the scheme. As shown in Figure 6 The electronic device divides the program update file into 128 Byte individual data streams according to the Ymodem protocol locally, or the diagnostic controller of the motor diagnostic device divides the entire target program file into 128 Byte individual data streams according to the Ymodem protocol in the SD card.

[0163] The motor diagnostic device receives the data stream sent by the electronic device based on Bluetooth & WIFI, or reads the data stream from the SD card. Then, the motor diagnostic device sends the data stream to Rx2 of the serial port 2 of the motor diagnostic device. The diagnostic controller of the motor diagnostic device receives the data stream and forwards it to the motor controller of the motor device through Tx1 of the serial port 1 to the predetermined Flash address. Wherein, Tx is the Transmit data sending port.

[0164] After the motor controller of the motor device writes the data stream, the motor controller of the motor device sends a response character to Rx1 of the motor diagnostic device, and the diagnostic controller of the motor diagnostic device sends it to the electronic device end through TX2 of the serial port 2. After receiving the response instruction, the electronic device transmits the next program data stream. In turn, the transmission of the entire program file is completed. Wherein, Rx is the Recieve data receiving port.

[0165] The J-Flash is used to read the bin file of the program to be updated. The program file is stored in the mobile device APP or the SD card. After completing the program upgrade, the STM 32CubeProgrammer is used to read the Flash data of the predetermined address, and the data is consistent, the program update is successful, the APP displays 29KB program file, the download rate is 1KB / sec, and the total time is 22s, which can complete the motor controller program upgrade. As shown in Figure 6

[0166] The motor controller of the motor device uses the J-Flash to read the bin file of the program to be updated and stores it in the electronic device or the SD card. After completing the program upgrade, the motor controller of the motor device uses the STM 32CubeProgrammer to read the Flash data of the predetermined address, and if the data is consistent, the program update is successful. Exemplary, the electronic device can display 29KB program update file, the download rate is 1KB / sec, and the total time is 22s, which can complete the motor controller program upgrade of the motor device.
