石油天然气管道泄漏在线监测报警装置，是根据我国石油天然气管道铺设情况，特别是天然气管道铺设经过人员密集区村镇公路桥梁和涵洞时，沿途管道经常遭受重压受损，也经常遭遇泥石流冲击等灾害，容易导致焊疤和连接处产生漏气，遇高温明火极易产生爆炸。所以在人员密集区管道经过的区域，在管道焊疤和管道连接处安装石油天然气泄漏在线监测报警装置，该装置通过太阳能供电，阴天可连续供电15天以上，智能红外天然气泄漏监测报警仪安装于测点堰井，堰井采用双红外探头设计，检测信号通过GPRS全网通模块发送到管道局监控平台，一旦检测到微量泄漏，测点现场会立即启动高分贝防爆声光报警器，提醒周边群众疏散至有效距离外，报警信号同时通过GPRS无线方式发送到沿途管道局平台，平台通过及时切断沿途上下游闸阀，减小压力等措施的同时，立即安排现场排查检修，从而避免事态进一步扩大，和产生爆炸的危险。
