Analysis of Switch Machines' Current Curve Based on Wavelet Time and Frequency Analysis
Haixiang Lin · Journal of Lanzhou Jiaotong University · 2012
A kind of method of switch machines' current curve analysis is proposed based on wavelet time and frequency analysis.According to the characteristics of the curve,this method can recognise the kind of failure happened,so it can induce the artificial error.This paper introduces basic analysis method of wavelet time and frequency analysis and the advantages of it.
