Design of Spacecraft Electrical Load Monitoring System Based on STM32

At present, the communication error correction rate of the electrical load monitoring system is low, which leads to the result of logic code writing is not consistent with the actual situation, resulting in the poor accuracy of spacecraft electrical load monitoring. In order to solve this problem, a new spacecraft electrical load monitoring system is designed based on STM32. The hardware and software of the electrical load monitoring system are designed respectively. The hardware of the system mainly designs embedded data interface, external equipment, driver chip and monitoring relay control module. WLAN driver chip can effectively reduce cost and power consumption and improve communication rate. The software function is realized through the implementation of electrical load monitoring, and the software of power load management center is established to improve the communication ability of the monitoring system and the accuracy of load monitoring. The experimental results show that the spacecraft electrical load monitoring system based on STM32 can effectively improve the communication error correction rate, enhance the logic code writing results and actual results, has high accuracy for spacecraft electrical load monitoring, and has a certain practical application.
