[0068] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0069] As an important part of air conditioning and ventilation systems, the motor is a driving device that is often installed with the whole machine on the roof, inside or outside the wall, and other places that are not easy to maintain. Usually, for the consideration of heat dissipation, the motor manufacturer will fill the motor controller with gel and firmly install it with the motor structure. Only the communication line is led out from the controller, and the power supply and control harness are led out through the reserved holes of the structure to feedback the motor operation information to the air conditioner main board or other control board.

[0070] When the system is abnormal, to locate and check whether the motor is abnormal, maintenance personnel need to use maintenance tools to carefully check the motor, and fault location is difficult.

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

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

[0073] Specifically, Figure 2 As shown, the motor device includes a motor controller. The electronic device can be a terminal device, which can be a mobile phone, a computer, a tablet computer, etc. The application embodiment does not specifically limit the electronic device.

[0074] Optionally, the motor controller of the motor device is provided with a control harness and a communication line, etc., the motor diagnostic device can be connected to the motor controller of the motor device via the communication line, and the electronic device is connected to the motor diagnostic device wirelessly via Bluetooth or WIFI. The motor diagnostic device may also include a rechargeable battery to provide power to the motor diagnostic device.

[0075] Among them, the communication line can be a communication method with strong anti-interference ability such as RS485, RS422, CAN communication, etc.

[0076] Among them, the full name of RS-485 is "Recommended Standard 485", which means "Recommended Standard 485" in Chinese. It is a serial communication standard that uses differential signal transmission, has strong anti-interference ability, and can achieve long-distance and multi-point communication. The full name of RS-422 is "Recommended Standard 422", which means "Recommended Standard 422" in Chinese. RS-422 is also a serial communication interface standard that also uses differential signal transmission, but unlike RS-485, RS-422 is full-duplex communication, while RS-485 is half-duplex communication. The full name of CAN is "Controller Area Network", which means "Controller Local Area Network" in Chinese. It is a serial communication network that effectively supports distributed control or real-time control, has the characteristics of high performance and high reliability, and is widely used in automotive electronics, industrial automation and other fields.

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

[0078] Specifically, the motor diagnostic device receives the operating data and initial fault identification corresponding to the motor device sent by the motor device; analyzes the initial fault identification, determines the target fault description information corresponding to the motor device, ensures the accuracy of the target fault description information corresponding to the determined motor device, and realizes the diagnosis of the motor. Then, the target fault description information and operating data are transmitted to the electronic device so that the electronic device displays the target fault description information and operating data, so that the maintenance personnel can locate the motor fault position according to the target fault description information and operating data. The efficiency of motor diagnosis is improved. In addition, the above method solves the problems of high maintenance cost, low efficiency and inability to provide after-sales service for motor equipment returned to the factory.

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

[0080] In this embodiment, a motor diagnosis method is provided, which can be used for the motor diagnosis device in 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 is communicatively connected with the motor diagnosis device. Figure 3 is a flow chart of a motor diagnosis method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

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

[0082] Specifically, the motor diagnostic device may periodically send request information for reading operating data and initial fault identification to the motor controller in the motor device based on the communication connection between the motor diagnostic device and the motor controller in the motor device.

[0083] After receiving the request information for reading the operating data and the initial fault identification sent by the motor diagnostic device, the motor controller in the motor device sends the operating data and the initial fault identification corresponding to the motor device to the motor diagnostic device.

[0084] It should be noted that the initial fault identifier may be obtained after the motor controller performs fault diagnosis based on the operating data of the motor device.

[0085] The operating data may include DC bus voltage, actual speed and other operating data.

[0086] Exemplarily, as shown in Table 1, this is the communication data between the motor diagnosis device and the motor device.

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

[0088]

[0089] DATA may be an initial fault identifier, and the fed-back DATA data is 2 bytes.

[0090] Step S102: Analyze the initial fault identifier to determine target fault description information corresponding to the motor equipment.

[0091] Specifically, after receiving the initial fault identifier, the motor diagnostic device may analyze the initial fault identifier according to the correspondence between the fault identifier and the fault description information, and determine the target fault description information corresponding to the motor device.

[0092] Exemplarily, the correspondence between the fault identification and the fault information may be as shown in Table 2.

[0093] Table 2 Correspondence between fault identification and fault information

[0094] NO. Fault identification Fault description 1 0x0000 No trouble 2 0x0001 Over temperature protection 3 0x0002 Three-phase power supply phase loss 4 0x0004 Overcurrent protection 5 0x0008 Motor stall protection when starting 6 0x0010 Output phase failure 7 0x0020 Undervoltage fault 8 0x0040 Overvoltage fault

[0095] Optionally, the target fault description information supports superposition. That is, if the motor controller has an over-temperature protection fault and an over-current protection fault at the same time, the motor controller feedback initial fault identification is 0x0001+0x0004, which equals 0x0005. After the after-sales personnel conduct on-site inspection and solve the problem that caused the over-current protection fault, the motor controller will automatically clear the initial fault identification 0x0001 corresponding to the over-temperature protection fault and retain the initial fault identification 0x0004 of the over-current protection fault.

[0096] Step S103: transmitting the target fault description information and the operating data to the electronic device so that the electronic device displays the target fault description information and the operating data.

[0097] Specifically, after determining the target fault description information, the motor diagnostic device can transmit the target fault description information and the operating data to the electronic device in a general Modbus RTU protocol format based on the communication connection with the electronic device. The electronic device displays the target fault description information and the operating data.

[0098] In an optional implementation of the present application, the motor diagnostic device may also choose to store the motor feedback data directly in an SD card, and use a digital tube to display the target fault description information and operating data.

[0099] In an optional implementation of the present application, the motor diagnostic device may store the target fault description information and the operating data in a storage space, and then display the target fault description information and the operating data based on the digital tube.

[0100] The motor diagnosis method provided in the embodiment of the present application receives the operation data and initial fault identification corresponding to the motor device sent by the motor device; analyzes the initial fault identification, determines the target fault description information corresponding to the motor device, ensures the accuracy of the target fault description information corresponding to the determined motor device, and realizes the diagnosis of the motor. Then, the target fault description information and the operation data are displayed, so that the maintenance personnel can locate the motor fault position according to the target fault description information and the operation data. The efficiency of motor diagnosis is improved. In addition, the above method solves the problems of high maintenance cost, low efficiency and inability to provide after-sales service for motor equipment returned to the factory.

[0105] Specifically, the above step S202 includes:

[0106] Step S2021, identifying the operating data and determining the candidate fault identification corresponding to the motor equipment.

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

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

[0109] Among them, the preset fault identification model can be generated by training based on preset training data, and the preset training data includes training operation data corresponding to the motor equipment and training fault identifiers corresponding to the training operation data.

[0110] Step S2022: compare the initial fault identifier with the candidate fault identifiers.

[0111] Specifically, the motor diagnostic device may compare the initial fault identification with the candidate fault identification.

[0112] Step S2023: Determine target fault description information corresponding to the motor device according to the comparison result.

[0113] Specifically, the above step S2023 may include the following steps:

[0114] Step a1: if the initial fault identifier is consistent with the candidate fault identifier, then according to the corresponding relationship between the fault identifier and the fault description information, determine the target fault description information corresponding to the initial fault identifier.

[0115] Specifically, if the initial fault identifier is consistent with the candidate fault identifier, the motor diagnostic device can determine the target fault description information corresponding to the initial fault identifier or the candidate fault identifier based on the corresponding relationship between the fault identifier and the fault description information.

[0116] Step a2: if the initial fault identifier is inconsistent with the candidate fault identifier, determine the first fault description information corresponding to the initial fault identifier and the second fault description information corresponding to the candidate fault identifier according to the corresponding relationship 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 the first fault description information corresponding to the initial fault identifier and the 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: Integrate the first fault description information and the second fault description information to generate target fault description information.

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

[0120] Step S203: display the target fault description information and operation data.

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

[0122] The motor diagnosis method provided in the embodiment of the present application identifies the operating data, determines the candidate fault identifier corresponding to the motor device, and ensures the accuracy of the determined candidate fault identifier corresponding to the motor device. The initial fault identifier is compared with the candidate fault identifier; if the initial fault identifier is consistent with the candidate fault identifier, the target fault description information corresponding to the initial fault identifier is determined based on the correspondence between the fault identifier and the fault description information, thereby ensuring the accuracy of the determined target fault description information. If the initial fault identifier is inconsistent with the candidate fault identifier, the first fault description information corresponding to the initial fault identifier and the second fault description information corresponding to the candidate fault identifier are determined based on the correspondence between the fault identifier and the fault description information, thereby ensuring the accuracy of the determined first fault description information and the second fault description information. The first fault description information and the second fault description information are integrated to generate the target fault description information, thereby ensuring the accuracy of the generated target fault description information. The inaccuracy of the target fault description information determined based only on the initial fault identifier is avoided.

[0130] Step S304: if the target fault description information is that the program in the motor device is not updated, then receiving a program update file sent by the electronic device.

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

[0132] Specifically, if the target fault description information is that the program in the motor device has not been updated, the electronic device can receive the program update file input by the user, and can also 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 diagnostic device according to the Ymodem protocol based on the communication connection between the motor diagnostic device and the motor diagnostic device when determining that the target fault description information is that the program in the motor device has not been updated, so that the motor diagnostic device can receive the program update file sent by the electronic device. The electronic device can also send the program update file to the motor diagnostic device according to the Ymodem protocol based on the communication connection between the motor diagnostic device and the motor diagnostic device after receiving the sending instruction of sending the program update file input by the user, so that the motor diagnostic device can receive the program update file sent by the electronic device.

[0138] Among them, the preset verification method can be any one of the verification methods such as parity check, cyclic redundancy check, hash check, etc. The embodiment of the present application does not specifically limit the preset verification method.

[0139] Step S3052: sending the target verification value to the electronic device, so that the electronic device compares the target verification value with the initial verification value corresponding to the program update file to generate verification result information.

[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 the 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 has been successfully checked; if the target check value is inconsistent with the initial check value, the check result information indicates that the program update file has been unsuccessfully checked.

[0141] Step S3053, receiving verification result information sent by the electronic device.

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

[0143] Step S3054: Determine whether the program update file is successfully verified based on the verification result information.

[0144] Specifically, the motor diagnostic device identifies the verification result information. If the verification result information shows that the target verification value is consistent with the initial verification value, it is determined that the program update file verification is successful; if the verification result information shows that the target verification value is inconsistent with the initial verification value, it is determined that the program update file verification is unsuccessful.

[0145] Step S306 : if the program update file verification succeeds, the program update file is transmitted to the motor device based on the communication connection between the motor devices.

[0146] Specifically, if the program update file verification succeeds, 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 verification fails, the program update file is received again from the electronic device.

[0148] Specifically, if the program update file verification fails, the motor diagnostic device receives the program update file sent by the electronic device again.

[0149] In another optional implementation of the present application, if the target fault description information is that the program in the motor device has not been updated, the motor diagnostic device receives the program update file sent by the electronic device. After the motor diagnostic device receives the program update file sent by the electronic device, it 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 the initial verification value corresponding to the program update file to generate verification information. According to the verification result information, it is determined whether the verification of the program update file is successful. If the verification of the program update file is unsuccessful, the motor diagnostic device receives the program update file sent by the electronic device again.

[0150] Step S308, receiving user instructions.

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

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

[0153] In an optional implementation, after receiving the user instruction, the motor diagnostic device can read the target program file stored in a storage device corresponding to the motor diagnostic device, wherein the storage device is pluggable and connected to the motor diagnostic device.

[0154] Exemplarily, after receiving the user instruction, the motor diagnostic device can read the target program file stored in the 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 diagnosis device transmits the target program file to the motor device.

[0157] For example, when electromagnetic interference is severe at the industrial site, the quality of wireless signal transmission is poor. Figure 2 As shown, the motor diagnostic device has an SD card reading function. Insert the SD card containing the target program file into the card slot of the motor diagnostic device and press the program update button of the motor diagnostic device to transmit the target program file transmission link to the motor controller of the motor device in a wired manner with better shielding 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 diagnostic method provided by the embodiment of the present application, if the target fault description information is that the program in the motor device has not been updated, then the program update file sent by the electronic device is received, the program update file is verified based on a preset verification method, and a target verification value is generated, thereby ensuring the accuracy of the generated target verification value. The target verification value is sent to the electronic device so that the electronic device compares the target verification value with the initial verification value corresponding to the program update file to generate verification result information; the verification result information sent by the electronic device is received; based on the verification result information, it is determined whether the verification of the program update file is successful, thereby ensuring the accuracy of the result of whether the verification of the program update file is successful.

[0159] If the program update file is successfully verified, the program update file is transmitted to the motor device based on the communication connection between the motor devices, thereby 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, thereby solving the failure of the motor device and ensuring that the electronic device can work normally. The problem in the prior art that when new and old motors need to be optimized and upgraded, the programming port of the chip is covered by glue, making the upgrade operation difficult is solved. If the program update file is unsuccessful in the verification, 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 operation of the motor device.

[0160] In addition, the motor diagnostic device can also receive user instructions; based on the user instructions, the target program file stored in the storage device corresponding to the motor diagnostic device is read to ensure the accuracy of the read target program file. The target program file is transferred to the motor device. This ensures that the motor device can receive the target program file. This solves the problem in the prior art that the 4G5G signal coverage strength at the industrial site is low, or the electromagnetic interference at the site is serious, the wireless signal transmission is unstable, and the success rate of uploading and downloading data using the cloud server is low.

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

[0162] For example, taking the DM series motor as an example, the communication line is mainly RT communication line (simplex). The diagnostic controller of the motor diagnostic equipment adopts the serial port idle interrupt and uses the two serial ports transparent transmission solution. Figure 6 As shown, the electronic device locally divides the program update file into 128-Byte separate data streams according to the Ymodem protocol, or the diagnostic controller of the motor diagnostic device divides the entire target program file into 128-Byte separate 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. After receiving the data stream, the diagnostic controller of the motor diagnostic device forwards it to the Flash address predetermined by the motor controller of the motor device through Tx1 of the serial port 1. Among them, Tx is the Transmit data sending port.

[0164] After the motor controller of the motor device completes writing the data stream, the motor controller of the motor device sends a response character to the motor diagnostic device Rx1, and the diagnostic controller of the motor diagnostic device sends it to the electronic device end through TX2 of serial port 2. After receiving the response instruction, the electronic device transmits the next program data stream. This is done in sequence to complete the transmission of the entire program file. Among them, Rx is the Recieve data receiving port.

[0165] Use J-Flash to read the bin file of the program to be updated. Save the program file in the mobile device APP or SD card. After the program upgrade is completed, use STM 32CubeProgrammer to read the Flash data at the predetermined address. If the data of the two are consistent, the program update is successful. The APP displays a 29KB program file, the download rate is 1KB / sec, and the total time is 22s to complete the motor controller program upgrade. Figure 6 shown.

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