-
摘要: 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.Abstract: It is a trend that the aircraft onboard machine-electronic equipment is controlled and managed integrated. 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 control and manage aircraft onboard machine-electronic equipment integrated are presented. The work feature and structure of the system, the communication network, the redundancy management and the real-time fault-tolerant administer software is discussed.
