天线伺服系统的冗余设计

Redundancy Design in Antenna Servo System

天线伺服系统是保证卫星通信质量的关键设备,必须确保其高可靠性,双机冗余设计是提高可靠性的一种有效方法。在对系统可靠性进行分析的基础上对传统天线伺服系统进行研究改进,提出热备份切换的双机冗余设计方案。介绍了系统架构、冗余部件、冗余方式选择、互锁切换机制和数据同步方式的设计思想,并对关键技术给出具体的实现方法,具有一定的实用价值。

The antenna servo system is pivotal equipment to ensure the quality of satellite communication, so high reliability is necessary. Dual hot-spare is an effectual method. On the basis of reliability analysis, the conventional antenna servo system is investigated and ameliorated,and dual hot-spare redundancy design scheme is presented. The design ideas of the system architecture, redundant components and structure choice,switchover control and data synchronization mode are introduced and the implementation of key technologies is given,which has certain practical value.
