The Research Of Expert System In Remote Fault Diagnosis

With the development of computer , communication and diagnosis technique ,and diagnosis requirement constantly improving , so put forward to the fault diagnosis method based on above technique together.Concept of the remote the remote fault diagnosis system is introduced.It consists of Web database ,security ,COM and so on.Then , after making the comparison of B/S mode with C/S mode ,the framework of remote diagnosis intelligent technology based on B/S mode and the architecture and function model of the system are established.Based on profoundly researching concerned technology, the thesis focuses on the key techniques ,which need the combination of expert system technique and neural network with net technique.The transportation , storage , loading of fault symptoms and data file , the way of visiting web database , the way of designing interface between web server and diagnosis server are discussed in the thesis.At last, prototype of system is established, and explored a long distance web site which has the function of preliminary diagnosis and demonstration.The server components is realized with Microsoft ASP technology, and the expert diagnosis component is realized with COM technology, and the neural network is realized by MATLAB technology.User can visit the fault diagnosis site in the remote place , and will be helpful to the remote fault diagnosis for complicated equipments.All of those can play an important role in industry field.
