Design of satellite power distribution and thermal control unit based on TMS570
Abstract： In order to adapt to the rapid development trend of low cost, short cycle, and mass production in domestic commercial aerospace, and in response to the current situation of low integration of various systems on the satellite, a satellite power distribution and thermal control management unit is designed with the microcontroller TMS570 as the core. Each module of the system is integrated using an internal bus, and communicates with the central computer through CAN bus for data exchange, achieving functions such as on/off control of power distribution for each component on the satellite, temperature collection and heating bands control for the satellite, power status monitoring, SADA driving, and software updating in orbit. The system has been applied to multiple satellites in the "Jilin-1" constellation, the ground and in orbit test results show that it has the characteristics of low power consumption, low cost, standard interface, high integration, and strong scalability.
