基于机载机电控制与管理计算机（USMC）容错技术的研究

机载机电系统是支持飞机正常、安全飞行工作所必需的,对飞机发动机和航空电子等设备的正常执行起着保障作用.为了提高机载机电系统的可靠性,机电系统采用了双余度结构,以达到故障容错,进而实现整个飞机系统的高可靠性和安全性.重点介绍了机载机电控制与管理计算机的容错体系结构的设计方案和工作原理,分析了系统的容错管理策略,研究了支持双余度计算机实现的故障检测及重构等关键技术.

Research on Fault-Tolerance Technique of New Style USMC

Utility systems are required for flight, they ensure aeroengine and aviation electronic devices working as usual. In order to improve the reliability of the system, redundancy technique is used in designing USMC. For the critical or important task, double redundancy management is adopted. This paper introduces the structure design scheme of the fault-tolerance system, principle of working and the implementation of fault-tolerance management strategy, studies the key techniques which provide the implementation of the double redundancy technique.
