【摘要】：针对煤矿井下管道运行情况监测采用人工巡查法存在的耗费人力、物力及突发状况下难以发现泄漏点的问题,基于光纤传感技术及负压波信号检测与定位原理设计了一种煤矿管道泄漏监测系统,给出了系统结构,介绍了光纤压力传感器增敏结构、负压波下降沿信号精确获取技术等系统关键技术,并对系统进行了长期运行试验和可靠性试验。试验结果表明,该系统运行稳定、可靠,能有效识别阀门开闭、泵启停等正常工况变化,并能对突发的管道泄漏进行定位,定位误差小于1%。
[Abstract]:It is difficult to find leakage points in coal mine underground pipeline operation monitoring by manual inspection method, such as wasting manpower, material resources and sudden situation. Based on the optical fiber sensing technology and the principle of detecting and locating the negative pressure wave signal, a leakage monitoring system for coal mine pipeline is designed. The structure of the system is given, and the sensitizing structure of the optical fiber pressure sensor is introduced. The key technologies of the system, such as the accurate acquisition of the negative pressure wave drop edge signal, have been carried out in the long-term operation test and reliability test of the system. The test results show that the system is stable and reliable, can effectively identify the valve opening and closing, pump start and stop and other normal conditions, and can locate the sudden pipeline leakage, the positioning error is less than 1.
