基于北斗与分布式光纤的天然气管道预警系统技术测试研究

Technical Test of Beidou Positioning Distributed Fiber Optic Based Natural Gas Pipeline Early Warning System

由于天然气管道老化和腐蚀,外部施工挖掘、爆破等第三方破坏,缺乏科学的管理维护,致使管道事故频繁发生,造成人民群众生命财产损失,城市天然气管道急需增加全天候、抗干扰、能精准定位的检测手段监测管道健康运行。北斗定位分布式光纤天然气管道预警系统能够24小时不间断的监控和预警,并且排除环境干扰因素对威胁管道安全的第三方破坏行为进行精确的识别并且能够精准定位破坏发生位置。本文针对北斗卫星定位分布式光纤预警系统进行一系列现场测试,为光纤管道预警系统保障燃气管道运行安全提供可靠依据。

Natural gas as an important part in the process of our country energy revolution,has important significance to social development and people's life,and pipeline transportation is the lowest cost,highest efficiency and the optimal management mode of transport.Due to aging and corrosion of natural gas pipelines,third-party damage such as external excavation and blasting,lack of scientific management and maintenance,pipeline accidents occur frequently,causing loss of people's lives and property.Therefore,it is urgent to increase all-weather,anti-interference and precise positioning detection means to monitor the healthy operation of gas pipelines.The Beidou positioning distributed fiber optic natural gas pipeline early warning system can monitor and give early warning for 24 hours without interruption,and eliminate environmental interference factors to accurately identify third-party damage behaviors that threaten pipeline safety and precisely locate damage locations.In this paper,a series of field tests are carried out for the distributed fiber optic early warning system of Beidou satellite positioning,which provides a reliable basis for the fiber optic pipeline early warning system to guarantee the safety of gas pipeline operation.
