Description

Technical Field

[0001] This invention relates to the field of data recording system technology, specifically to a domestically produced servo motor fault data recording system and method based on GD32. Background Technology

[0002] A servo motor is an actuator that controls the rotation of the control surfaces (rudder surfaces) of an aircraft in an autopilot. However, servo motors are prone to failure after prolonged use. Due to the unique operating environment of servo motors, it is necessary to record and process the fault data when a servo motor fails. Therefore, it is essential to design a domestic servo motor fault data recording system and method based on GD32. Summary of the Invention

[0003] The purpose of this invention is to provide a domestically produced servo motor fault data recording system and method based on GD32, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a domestically produced servo motor fault data recording system based on GD32, comprising a system power-on module, a GD32 initialization module, an SD controller initialization module, an ARINC429 initialization module, a CAN controller initialization module, a USB controller initialization module, an AD acquisition initialization module, a self-test module, a shutdown module, an alarm module, an OTC status reading module, a data export request module, a configuration SDIO read / write module, a data update module, a data reading module, an RTC time reading module, a host interaction module, a USB flash drive detection module, a USB flash drive configuration module, and a data storage module. The system power-on module is connected to the GD32 initialization module, which in turn controls the SD controller initialization module. The SD controller initialization module is connected to the ARINC429 initialization module, which in turn controls the CAN controller initialization module. The CAN controller initialization module is connected to the USB controller initialization module, which in turn controls the AD acquisition initialization module. The AD acquisition initialization module is connected to the self-test module.

[0005] Preferably, the self-test module is controlled by a shutdown module and an OTC status reading module, and the shutdown module is controlled by an alarm module.

[0006] Preferably, the OTC status reading module is connected to a request to export data module.

[0007] Preferably, the request to export data module is controlled by a configuration SDIO read / write module and a detection USB flash drive module, the detection USB flash drive module is controlled by a configuration USB flash drive module and a host interaction module, and the host interaction module is connected in conjunction with an OTC status reading module.

[0008] Preferably, the configured SDIO read / write module is connected to a data update module, the data update module is connected to a data read module, and the data update module is connected to an OTC status read module.

[0009] Preferably, the data reading module is connected to an RTC time reading module.

[0010] Preferably, the RTC time reading module is connected to a data storage module, and the data storage module is connected to an OTC status reading module.

[0011] The method for recording fault data of domestic servo motors based on GD32 includes the following steps: Step 1, self-test; Step 2, interaction; Step 3, reading; and Step 4, storage.

[0012] In step one above, the system power-on module is used to power on the system. After power-on, the GD32 initialization module, SD controller initialization module, ARINC429 initialization module, CAN controller initialization module, USB controller initialization module and AD acquisition initialization module are initialized sequentially. Then, the self-test module is used to perform a self-test. If the self-test of the servo fails, the shutdown module is used to stop the system first, and then the alarm module is used to sound an alarm. If the self-test of the servo succeeds, the OTC status is extracted by the OTC status reading module.

[0013] In step two above, a data export request is made through the data export module. After the request is approved, the USB flash drive detection module checks whether the USB flash drive is working or in a normal state. If the USB flash drive is damaged or not working, the USB flash drive is configured through the configured USB flash drive module. After the configuration is completed, the host interaction module performs host interaction. After the interaction, the OTC status is retrieved again. If the data export request from the data export module fails, the SDIO read / write configuration module is used to configure SDIO read / write. Then, the data is updated through the data update module, and the updated data is read through the data read module.

[0014] In step three above, the RTC time is read using the set RTC time reading module and stored in the storage data module;

[0015] In step four above, the data in the storage module is read cyclically, and automatically loops when full. It simultaneously stores the acquired data and time stamp information. The ARINC429 data acquisition interface of the initialization module is implemented through SPI extension, communicating via the SPI bus in SPI mode 0, supporting a maximum communication rate of 10MHz, which meets the ARINC429 communication rate. The main registers include the receive control register, transmit control register, ACLK frequency divider register, and flag interrupt register. Initialization requires configuring these registers to ensure normal communication. When receiving data, the LABEL of the received 429 message needs to be flipped, RFLIP needs to be set to 1, PARITY to 1 to enable parity checking, LABREC and PLON need to be set to 0 to disable tag filtering, and RATE needs to be set to 0, setting the 429 communication rate to high speed 100kbps.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the system can record and process the fault data of the servo motor, which facilitates the subsequent maintenance or repair of the servo motor and improves the safety of using the servo motor. At the same time, an alarm module is set up during the fault data collection process. The alarm module can promptly remind the staff of the servo motor malfunction, which can facilitate timely handling and improve safety. Attached Figure Description

[0025] Please see Figure 5 The present invention provides an embodiment of a method for recording fault data of a domestically produced servo motor based on GD32, comprising the following steps: Step 1, self-test; Step 2, interaction; Step 3, reading; and Step 4, storage.

[0026] In step one above, the system power-on module 1 is used to power on the system. After power-on, the GD32 initialization module 2, SD controller initialization module 3, ARINC429 initialization module 4, CAN controller initialization module 5, USB controller initialization module 6, and AD acquisition initialization module 7 are initialized sequentially. Then, the self-test module 8 is used to perform a self-test. If the self-test of the servo fails, the shutdown module 9 is used to stop the servo first, and then the alarm module 10 is used to trigger an alarm. If the self-test of the servo is successful, the OTC status is extracted by the OTC status reading module 11.

[0027] In step two above, the data export request is made through the data export module 12.

[0028] In step three above, the RTC time is read using the set RTC time reading module 16 and stored in the storage data module 20;

[0029] In step four above, the data in the storage module 20 is read cyclically, and automatically loops when full. It simultaneously stores the acquired data and time stamp information. The ARINC429 data acquisition interface of the ARINC429 initialization module 4 is implemented via SPI extension, communicating via the SPI bus in SPI mode 0, supporting a maximum communication rate of 10MHz, which meets the ARINC429 communication rate. The main registers include the receive control register, transmit control register, ACLK frequency divider register, and flag interrupt register. Initialization requires configuring these registers to ensure normal communication. During data reception, the LABEL of the received 429 message needs to be flipped, RFLIP needs to be set to 1, PARITY to 1 to enable parity checking, LABREC and PLON to 0 to disable tag filtering, and RATE to 0, setting the 429 communication rate to high speed of 100kbps.

[0030] Based on the above, the advantages of this invention are that, during use, the servo motor can perform self-testing and record fault data that occurs during the self-testing process, thereby improving the safety of using the servo motor. In addition, an alarm module 10 is set up, which can promptly remind the staff of servo motor malfunctions, facilitating timely handling and improving safety.
