摘要
小波变换具有良好的时 -频局部化特性 ,是信号的时 -频域分析和处理的有效方法 .简要论述了有关小波变换的基本理论 ,介绍了小波变换在异步电动机转子断路故障诊断的原理 ,给出了信号检测电路的组成 .
Wavelet transform with the good partial characteristic in time?frequency regions is an effective way to make time?frequency analysis and processing of the signals.It has mainly discussed the basic theory of wavelet transform,and introduced the principle of the diagnosis in the open?circuit rotor of asychronous motor with wavelet transform.The construction of signal detection circuit is given as well.
