In order to solve the problem of fault diagnosis for a variety of complex spacecraft systems, this paper discusses the establishment of a platform technology for fault diagnosis of spacecraft systems, and analyzes the overall structure of the software platform for spacecraft fault diagnosis systems. In-depth study of the requirements of the fault diagnosis platform as the core part of the software platform, structure, function and system components, design the overall structure of the diagnostic platform system. Application of event algebra method, distributed thinking and Powerbuilder technology as a diagnostic platform for task management strategies and operational rules. Finally, through the actual research on the fault diagnosis system of spacecraft system, it is proved that the technique is effective and feasible.
