Research on and implementation of diagnosis platform in spacecraft fault diagnosis software platform

Because of the increasing complexity of spacecraft fault diagnosis, it is necessary to explore the platform technique for spacecraft of fault diagnosis software. The general architecture of software platform of fault diagnosis for spacecraft is analyzed. The general software platform consists of network platform, database platform and fault diagnosis platform etc. The architecture and function of the diagnosis platform, which is the kernel part of the software platform, are researched deeply and designed.The event algebra and distributed calculation and Powerbuilder are applied for database structure and distributed task management policies. Finally, the efficient and feasible of these technique are proved in fault diagnosis of spacecraft.
