摘　　要：管道已经成为石油、天然气最重要的运输工具,但其安全问题也越来越突出。文章介绍了由中国石油天然气管道通信电力工程总公司研制的一种基于光纤传感激光干涉技术的管道安全预警系统,利用与管道同沟敷设的通信光缆作为分布式传感器,对管道沿线的土壤振动情况进行长距离实时监测,通过对管道沿线土壤振动信号的智能分析,判断出威胁管道安全的破坏事件,并对目标实现精确定位和准确报警,从而实现对管道安全的预警。A pipeline early-warning system based on optical fiber laser interference technique is developed by CPP Pipeline Communication and Electric Power Co. It applies the communication optical fiber cable buried in the same pipeline trench as distributed sensors to conduct the long-distance real-time monitoring of soil vibration along the pipeline. Through the intelligent analysis on the vibration signals, it judges the event threatening pipeline safety and makes accurate locating for the event and gives an alarm so that to implement the early-waning for pipeline.
