Design of Distributed Fault-Tolerant System for UMS

综合控制管理是机载机电设备发展的趋势 .针对航空机电设备综合控制管理预研项目 ,利用分布式容错技术、高可靠航空电子总线技术和嵌入式实时多任务操作系统应用技术 ,设计并实现了一个分布式容错计算机系统 .讨论了系统的工作特点、系统结构、通信网络、冗余管理和实时容错分布执行软件 .

Integrated control and management is a trend of development for onboard machine-electronic equipment. Based on distributed fault tolerant technique, high reliable bus technique of avionics and application technique of embedded real-time operation system, a design and an implementation of a distributed fault tolerant computer system which can provide integrate control and management for onboard machine-electronic equipment are presented. The feature and structure of the system, the communication network, the redundancy management and the real-time fault-tolerant administer software is discussed.
