| Abstract: | In order to ensure the safe running of electromechanical equipments, the running condi- tion of the rotation machine should be monitored in real time and the crackle fault of the shaft should be detected in time. Data-Acquisition system is constructed for acquiring the vibration signal in real time. The soft module for data analysis and management is development based on the G language labview. A diagnosis expert systerm of shaft crackle is made. The acquisition, disposal and transmission of vibration signal are also realized. The system can be able to monitor the running condition effectively and remove the hidden danger of the equipments. |
