This article expatiates the theory on hydraulic system s leakage fault.

The oil pipeline leakage diagnosis system,based on GIS,making full use of GIS platforms,and combining the existing pipeline leakage positioning theory,has many virtues such as geographic information online display,positioning accuracy,rapid response,and sound warning,discarding shrinking and enlarging.

Along with the rapid development and widespread application of digital technologies,the digitization technologies have already become one important part of long-distance oil pipeline leakage diagnosis.

For reasons of low accuracy of traditional leakage,a pipeline leakage diagnosis method based on neural networks and evidence theory is presented by introducing wireless sensor networks and information fusion theory.
