Data Acquisition Of Remote Fault Diagnosis Based On Embedded

The technology of fault diagnosis (FD) is a new intercross technical science. Since it was applied to industrial enterprises, it has brings great benefits to the social and economic development. The research and application of FD developed quickly. With the development of computer and communication technology, the application of computer network is more and more common in modern society. The technology of computer network, especially the technology of Internet makes the study and applications of remote fault diagnosis (RFD) become possible. Embedded system has flexible, special and universal excellence. These advantages offer new orientation of remote fault diagnosis system development.The papers discuss the study and implement of the data acquisition of RFD based on embedded. The papers consist of the following parts: (1) Gathering locale data and long-distance transmitting embedded system based on PC/104 stackable frame. (2) Using network, Internet application and hardware to design remote monitoring system (3) Using the method of frequency spectrum analysis and remote matching to diagnose fault.
