Remote Intelligent Fault Diagnosis System

With the development of technology, the structure of equipment is more complicated, and the character of global and customized tendency of manufacturing system is represented, so traditional fault diagnosis technologies can not adapt to the requirement to fault diagnosis for complicated devices. In the paper, remote intelligent fault diagnosis technology and system is studied to solve the problem economically, rapidly and effectively.Based on an analysis of the requirement of modern manufacturing system to fault diagnosis for complicated devices, the concept of remote intelligent fault diagnose system is put forward, and the architecture and function model of the system are established, and the principle of work of the system is proposed; Then, diversified technologies of realization of the system are studied, which are groundwork of the system; Then, associated with "MS730CP5 automatic door systems for railway rolling", the theories of Expert System and Artificial Neural Network are analyzed in details and used for intelligent fault diagnosis; Last, a prototype of the system is established. The style of the system is network, the server component is realized with Microsoft ASP technology and the intelligent diagnosis components are realized with COM technology. User can visit the fault diagnosis site in the remote place, that will be helpful to the remote fault diagnosis for complicated devices. Under the LAN environment, the prototype is realized and run well.
