摘　　要：针对航天飞行器在高空挂飞过程中,外界温度低于-40℃,很多元器件的无法正常工作,从而导致产品无法启动或工作出现故障.本文采用基于DSP的1553B总线技术以及采用高可靠性硬件比较电路实现对飞行器舱内温度的控制,使其保持在10℃~30℃之间,从而保证舱内设备能够正常工作,提高系统安全性和可靠性.In the process of hanging the spacecraft in the air,the external temperature is lower than-40℃,many components can not work normally,resulting in the product can not start or work failure.In this paper,using DSP based 1553B technology and high reliability hardware comparison circuit are adopted to control the temperature in the cabin of the aircraft to keep it between 10℃and 30℃,so as to ensure the normal operation of the equipment in the cabin and improve the security and reliability of the system.
