Design of distributed fault-tolerant system for UMS

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.
