Leak Detection Research of Water Supply Pipeline Based on HHT

摘要：

　　In this paper,the leak detection problem of water supply pipeline,the main sound source and its generating mechanism were studied.The authors use the power spectrum and the Hilbert Huang transform analysis of the vibration frequency characteristics of acoustic signal,and use them for leak detection.Design a set of water supply pipeline leak detection and alarm system based on MATLAB GUI and sensor,acquisition card and other peripheral equipment combined with the hardware and software,and realize the water supply pipeline leak detection.Validate and analyze the proposed scheme by collecting a large number of acoustic signals of different leakages through the experiment.The system is verified with more than 96%accurate rate,and has a certain practical application value.
