英文摘要：

Aiming at the shortage of large power consmnption, unreliable network communication and different system time on pipeline online monitoring, a new oil pipeline leakage detection and positioning system based on embedded PC104 is designed. Use the GPS time service technology and LAN between central PC and remote terminal unit. The detection principle, hardware structure and software design of the system are introduced in detail. The test and actual application show that the system operates stably, and its power consumption is low and integrity, reliability and real-time performance of remote data transmission is guaranteed. It is able to correctly identify the pipeline leakage, and nlake accurate positioning,
