Abstract
In order to ensure the stable, reliable and healthy operation of spacecraft, this paper introduces the spacecraft expert diagnosis system for real-time monitoring and early warning of spacecraft. The inference engine is the core of the spacecraft expert system. Each inference engine is responsible for a spacecraft monitoring and early warning. How to ensure the stable and reliable operation of the inference engine is an urgent problem to be solved. In this paper, agent technology is introduced to monitor the reliable operation of the inference engine and process migration when the inference engine fails. At the same time, monitor server resource utilization for process scheduling to achieve server load balancing. Practice has proved that the system can greatly improve the stability of the inference engine, improve the efficiency of spacecraft management, and save a lot of manpower and material resources.
