摘　　要：介绍基于虚拟仪器技术构建的异步电机检测系统,实现了异步电机系统的参数检测和故障诊断。文章将基于LabVIEW的小波包理论应用于电机故障诊断研究,将小波变换极大模分析方法应用于信号突变成分的检测,有效地定位并检测出异步电机中的早期故障。最后,通过实验证明了基于小波理论的故障诊断方法的可行性。The study introducs the detection system of asynchronous motor, which is built on the bas of virtual instrument technology. It has realized the detection of parameters and diagnosis of motor fault. The article takes wavelet packet theory which based on the LabVIEW into the reaserch of motor fault diagnosis. Wavelet transform modulus great mutation analysis method has been applied to components of signal detection, to locate and detect the early asynchronous motor fault effectively. The result of experiment shows the feasibility of the fault diagnosis method based on wavelet theorem.
