摘要
通过在某新型卫星立项攻关上的设计实例，介绍了一种设计方法；通过８０Ｃ３１单片机系统对有效载荷的温度变化进行及时采集监测，并根据卫星运行规律和温度控制要求对百叶窗进行及时有效的控制，在线路设计上采用了双ＣＰＵ系统控制和备份通道控制三套备份设计，极大地提高了控制线路工作的可靠性，能满足卫星工作的要求。
The large-area motor-driven louver has been used on the man-made satellites abroad , but it has yet not been used in our country's satellite. It use this paper introduces a design method for the motor-driven louver able to be used in the new type of satellite which made by our country. This device controls the louver's work according to satellite's moving law. It use two 80C31 systems and a backup control system, raising the device's working credibility largely.
