余度飞行控制计算机的组成架构分析

Architecture Analysis of Redundancy Flight Control Computer

从余度技术的概念与设计思想入手,介绍了二余度与三余度的飞控计算机组成架构。设计了三余度飞控计算机的硬件体系,并对其组成部分如CPU的选型、总线的确定进行了论述。余度飞控计算机具有很强的容错能力,使得在飞机发生故障时,余度飞控计算机能够快速准确地检测并隔离故障,采取重构策略,确保飞机能够继续执行任务或安全返航。

This paper from the concept of redundancy technique and design principle,introducing the architecture of dual- redundant flight control computer system and the triple- reduntdant flight control computer system. Systematically introducing the general architecture of the triple- reduntdant flight control computer,for system components such as CPU,bus isanalyzed in detail. Redundancy flight control computer has strong fault-tolerant ability that making the aircraft in the ecent of failure,quickly and accurately detecting and isolating the fault quickly and accurately. It can take the reconstruction strategy,ensure that the aircraft can continue to perform or safely coming back.
