Pipeline leak detection based on process information fusion

Considering the transient features of pipeline leak,a leak detection method based on process information fusion was presented.The pipeline leak features were analyzed.The extracting method of process information entropy based on process steady entropy,double channel singular spectrum entropy and double channel power spectrum entropy was introduced.The process fusion entropy was used to detect pipeline leak,combining GPS time label location method with GIS information.This method was used for leak monitoring of west products pipeline.The results show that this method has good performance on the accuracy of leak recognition and leak location.
