Study Of Condition Monitoring And Wavelet Transform In Diagnosis For Boiler Fans

There are two sessions in this research. In the first session a vibration test and off-line processing scheme is presented according to present on-line testing environments . After the data has been collected, attempt of wavelet transform is made combined with traditional Fourier analysis . Various methods of wavelet transform are tried to reveal the relations in transform figures. And the wavelet packet united with statistic analysis is used to show the fault characteristics intuitionisticly. This is the main part of this paper. In second session, the fans performance monitoring system is improved and realized with VC language instead of VB. Ren Ling(Power Plant Thermal Power Engineering) Directed by prof.
