Study on open equipment condition monitoring and fault diagnosis system based on internet

An open condition-monitoring system combined C/S (Client / Server) with B/S (Brower / Server) pattern was introduced. It consists of three parts of software: SE (Server-Terminal), ADE ( Analysis-Diagnosis-Terminal) and DAE ( Data-Acquisition-Terminal ). SE can monitor every connection request from ADE or DAE user and determinate whether ADE or DAE can be run on client's PC. As a result, the system security is improved in a sense. Additionally, the system hardware part comprises two kinds of terminal portable instruments: DASOC(data-acquisition system on chip based-on the Cygnal MCU) and DSAI(dynamic signal analysis instrument based on an embedded OS:XPE). DASOC and DSAI can realize data-acquisition, signal analysis and data-transmission based-on internet. The system structure mode has been applied to a certain power plant's enterprise information network in Tianjin. Results show that the system is successful.
