The Principle of Dynamic Diagnosis Based on Integrated Maintenance Information and its Application

Based on the concept of an integrated maintenance information system and related information environment, this paper discusses the process of troubleshooting in modern maintenance in detail, and gives a model of dynamic faults diagnosis, in which a reasoning program is designed through taking advantage of information fusion and time analysis. In the end, the authors present the logic process of dynamic diagnosis through a typical example, and propose a dynamic diagnostic system based on information fusion.
