摘要
本文介绍了一种已用于实际的完备冷冗余FDCS系统；监控器降级重构解决了双单元冗余的可靠性瓶颈问题；介绍了故障诊断原理及上位机冗余技术该系统现已以每24h不间断运行了2年，达到了可靠性设计要求。
This paper introduces the ideal outlineredundancy system which has already been used inpracticc. Thc degrading re form for monitor figures outthe key reliability problem in the two units redundancy system; and introduces the principle of failurediagnoses and the center computer redundancy. Thissystem has been working uninterruptedly every dayfortwoyears,achievescompletelytherequestforreliability.
