Fault Diagnosis System

The system uses GRAP in Grey Theory to conduct fault diagnosis of fan and chooses LabWEV for software platform, developing a set of system aiming at fault monitoring on line and diagnosis of mine fan in order to guarantee the running state of fan continuously and efficiently . This system has functions of monitoring on line,fault diagnosis,fault warning,data storage, history inquiry and so on.

In view of the present, the data acquisition system of the fault monitoring system is not perfect, so the data acquisition module of mechanical fault system of wind power generator is developed based on DSP, which better improves the on-line monitoring system. Firstly, the paper introduces the working principle of the module and the selection principle of set measuring point and monitoring point. Then, it introduces the design of hardware system in detail.
