石油管道泄漏检测与定位系统设计

The Leak Detection and Location System Design of Petroleum Pipeline

为了提高传统负压力波检测石油管道泄漏的灵敏度和定位精度,采用C/S架构设计了多点分布式的检测和定位监测系统,该系统由管道沿线检测节点、监测分站和监测中心三部分构成。检测节点采集管道内部的压力信号,并通过GPRS网络传输到监测中心,实现对整个管道压力的实时在线监测。利用多点分布式负压力波检测方法以及相关分析法理论对采集到的实时数据进行分析和处理,使系统具有更高的响应速度和定位精度。该系统能够迅速检测泄漏点并精确定位,避免造成巨大经济损失和环境污染事件的发生。

In order to improve the sensibility and location precision of petroleum pipeline leak with traditional negative pressure wave detection, a multi -point distributed detection and location monitoring system of detection nodes along pipeline, monitoring sub - stations and pressure monitoring center was designed using C/S structure. The detection node gets the pressure signal in pipeline, and sends it to monitoring center through GPRS network that achieves online monitoring for the whole pipeline in real time. The received data was ana- lyzed and processed with multi - point distributed negative pressure wave detection and correlation analysis method. The system can rapidly detect the leak point in pipeline timely and locate accurately to avoid enormous economic loss and environment pollutions accidents.
