Aiming at the shortage of large power consumption

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 make accurate positioning.
