GPS在集输管道异常位移监测技术中的应用

The Application of GPS in the Gathering Pipeline Abnormal Displacement Monitoring Technology

集输管道是石油、天然气的主要运输渠道,承担着能源运输的重大责任。一些重大管线如果发生事故,则给国家造成不可估量的损失。这就迫切需要解决管网事故率高的问题,以减少由此造成的不必要的损失。采用GPS系统来监测长距离集输管道的异常位移,具有全天候、高精度、自动化程度高等特点,并且卫星通信覆盖能力强,信号稳定,相对于人烟稀少的地点,更具有优势。本文介绍了利用GPS(RTK)技术监测集输管道实时位移的方法和实现途径。

Gathering pipeline is the major transportation channels of oil and natural gas, bearing significant responsibility for energy transport. Once a major pipeline accident occurred, the loss caused to the State will be immeasurable. There is an urgent need to solve problem of the high accident rate of pipe network, in order to reduce unnecessary losses. The features of that GPS system was applied to monitor and alarm the long-distance gathering pipeline abnormal displacement, which were all-weather, high-precision, high degree of automation, and satellite communications coverage ability, signal stability relative to the location of sparsely populated, make it more superiority. This article describes the method and available ways of GPS （RTK） technology to monitor real-time gathering pipeline displacement.
