Abstract:

The failure diagnosis technology is not only an important method to enhance the safety and reliability of spacecrafts, but a process to save the maintenance cost during the whole working period of spacecrafts. Thus, it is very significant to investigate the spacecraft failure diagnosis technology, especially the orbit checking and diagnosis technology for the emergent failure treatment. Base on the development of international space transfer vehicle failure diagnosis technology, which produces the integrated design idea of orbit and earth space transportation spacecraft failure diagnosis system structure, expounds the design principle, as well as the specific functional requirements. It introduces the on-board failure diagnosis system and ground failure diagnosis system, whose software component model is proposed. Ground failure diagnosis system is an important role in failure diagnosis on orbit, it can effectively complement the failure analysis, diagnosis, prediction, processing capacity. The system structure has certain reference value to the development of failure diagnosis system for spacecraft.
