基于虚拟仪器的原油管道泄漏监测系统

A Virtual Instrument-Based Oil Pipelines Leak Monitoring System

近年来我国原油泄漏事故频仍，造成巨大经济损失和环境污染，所以需要一个能够及时发现并精确定位的监测系统。我们使用Ｎａｔｉｏｎａｌ Ｉｎｓｔｒｕｍｅｎｔｓ公司的虚拟仪器开发平台ＬａｂＶＩＥＷ和数据采集卡，不间断采集压力、流量、温度等参数，监视管道运行状况，并利用电话线路构成通信网络，建立了一个实时性较好的监测系统。对于突发的原油泄漏，我们综合运用了包括小波分析在内的多种信号处理方法，能够及时准确地定位泄漏点。本系统已经成功地应用于胜利油田和华东输油管理局等集输管网和长输管线，取得了可观的经济效益。

Raw oil leakage has been an important problem these years in China, which will cause serious consequences, such as economic loss and environmental pollution. Thus a monitoring system which can detect the leakage and locate the leak point is required. National Instruments＇ graphical programming language, LabVIEW and DAQ board are used to acquire pressure, flow rate and temperature continuously, monitoring the condition of the pipeline. And with telephone communication net, a real-time monitoring system is established. Several methods of signal processing, including wavelet analysis are utilized. The system has played a big role in the pipeline network in Shengli Oil Field and long pipelines of East China Oil Bureau.
