| 摘 要： | Pipeline integrity defect is a considerable portion in all the defects.Therefore,the study on detection technique is of great concern to the owners of pipelines.A real-time monitoring system of pipeline defect is established.For unexpected accidents of pipeline leakage,several methods of signal processing,including wavelet analysis are utilized.The leakage can be located accurately in time.This system is applied to many long distance pipelines in China,which has made great contributions to the economy.

A real ti me monitoring system of pipeline defect is established. For unexpected accidents of pipeline leakage, several methods of signal processing, including wavelet an alysis are utilized. The leakage can be located accurately in time. This system is applied to many long distance pipelines in China, which has made great contri butions to the economy. |
