随着国内外天然气管道建设的迅速发展，管道的安全运行在当前尤为重要。采用基于Cortex—M3内核的高性能STM32处理器对管线中的声波进行采集和分析，从而判断出管道是否泄漏。在检测到泄漏之后，把泄漏信号远传到数据中心，在管道两端ms级时间同步的情况下能对泄漏点进行精确定位，实现了输气管道泄漏快速检测和报警的功能，以及管网的数字化智能监控。

With the rapid development of foreign and domestic natural gas pipeline construction, the safe operation of pipeline is partieu larly important in the current. High-performance STM32 processor based on Cortex-M3 core is used to collect and analyze sound waves in the pipeline, so as to determine whether the pipeline leaks or not. If the leak is detected,the leak signal is transfered to the data cen- ter, and the system can locate the leak point precisely in the ease of ms-class time synchronization at the both ends of the pipeline. The system achieves the gas pipeline leak rapid detection and alarm, and digital intelligent monitoring of sub pipeline network.
