基于小波分析的故障信号检测

Examination of Fault Signal Based on Wavelet Analysis

通过对不同小波基的选取进行比较,给出了用小波分析寻找故障点的方法.并结合故障分析实例做出仿真.仿真结果证明,该方法可以提高信号的分辩率,降低噪声,提高信噪比.

By comparison and selection of wavelet, a new method to find break down points is presented, giving simulation. The method increases resolving power of signal, lowers the noise and increases signal to noise ratio.
