Abstract :
This paper firstly brings forward a basic constitution of pipeline leakage detection system, introduces the main method of the leakage detection, then gives a detailed explanation of the properties of wavelet transform and de-noising principle. The main of the paper introduces the application of wavelet transform in analyzing the signals and eliminating noises. Taking two signals for example, wavelet analysis is used to make the partial characteristics of the signals distinct, and extract the characteristic signals from the original one, at last the paper indicates the realization course of leakage detection system
