余度架构设计是解决飞控计算机可靠性问题的有效途径。为了满足高可靠性飞控计算机系统对可靠性和容错性的特殊要求的目的,提出一种新型三余度飞控计算机的余度架构方案,描述飞控计算机冗余设计方法,设计余度计算机软硬件的总体框架,采用马尔可夫方法对该方案进行了可靠性分析,获得了故障覆盖率和失效率对飞控计算机整体可靠性的影响结果,得到所设计余度架构方案可行的结论。
The redundancy architecture design is an effective way to solve the problem of flight control computer reliability. In order to satisfy the special requirements of reliability and fault tolerance of high reliability flight control computer system, this paper proposes a redundancy scheme of the new three flight control computer, describes the redundancy design method of flight control computer, design redundancy computer Hardware and software, the reliability of the scheme is analyzed by Markov method, the influence of failure coverage and failure rate on the overall reliability of the flight control computer is obtained, and the feasible conclusion of the scheme is obtained.
