Remote Intelligent Fault Diagnosis System

Traditional fault diagnosis technologies of complicated device cannot adapt the global and customized tendency of manufacturing system. In this paper, remote intelligence fault diagnosis system is to solve the problem economically, rapidly and effectively.To meet the new requirements of complicated device fault diagnosis, this paper puts forward the concept of remote intelligence fault diagnosis system. It is an integration of many diagnosis subsystems by Internet/Intranet that can diagnose independently. They can cooperate to solve the complicated fault problem. In this paper, the whole structure, logical structure, function model and knowledge representation are researched thoroughly. Then the prototype of remote intelligence fault diagnosis system for engine is realized. The server component is realized with Microsoft ASP technology and the diagnosis subsystem components are realized with the DCOM technology. Expert System, Neural Network and Fuzzy Neural Network algorithms are used in the diagnosis subsystems and analyzed. Under the LAN environment, the prototype is realized and run well.
