The Development Of Distributed Rotating Machinery Condition Monitoring System Based On Ethernet

The present condition monitoring system is defective to monitor assistant rotating machinery in power plant. Failure can't be detected in time, because this machinery is always distributed and far from control center.The purpose of this paper is to develop a condition monitoring system of distributed rotating machinery based on embedded Ethernet.In this paper, firstly, several kinds of vibration mechanism which bring breakage to rotating machinery, the measuring and processing plans of vibration signal and the background knowledge of ethernet are analysized and introduced. Secondly, the design of hardware system includes acquisition and adjustment circuit, A/D conversion circuit, embedded processor and peripheral circuit, Ethernet interface circuit and so on. Thirdly, the software platform is embedded uClinux operation system. Then, the migration of uClinux and process of application development on this platform are introduced. And the program of transporting data through Ethernet is analyzed especially. At the last, conclusion of this paper and some problems which will be faced in succedent work are pronounced.The success of the development of distributed rotating machinery condition monitoring system based on Ethernet will bring economic benefits to power plant.
