【 摘 要 】

The leakage of flammable gas during pipeline transportation will cause waste of resources and environment pollution,even explosion which means great loss to human life and property.Therefore,the issue of leak detection of flammable gas pipeline is particularly important.This paper mainly applies the correlation analysis based on the negative pressure wave to detect the leakage of gas pipeline.And wavelet analysis is applied to denoise the noise contained in the collected pressure signals.In the end,the method is tested through simulation.
