| Abstract: | It is important to diagnose sensor fault. Based on the traditional fast Fourier transform ,spectrum analysis has its limitations and defects,and in order to overcome their disadvantage,so use wavelet transform to analyze signal. On the basis of introducing wavelet transform,this paper adopts wavelet transform technology to analyze faults of sensor and diagnose the faults of sensor quickly and correctly.The simulation experiment shows that wavelet transform is very effective to diagnose sensor,and achieves s... |
