摘　　要：针对油气管道第三方破坏的威胁,提出了一种基于相位敏感光时域反射仪的分布式光纤振动预警系统,分析了其用于油气管道安全预警的关键技术,并在某原油输送管道现场进行了测试应用。应用结果表明,系统可以准确监测管道附近的人为挖掘,通过多参量模式识别算法可使系统有效区分人为挖掘和干扰信号。Aiming at the threat of third-party interference on oil and gas pipeline,a distributed optical fiber disturbance pre-warning system was put forward based on phase-sensitive optical time-domain reflectometry.The key technology for oil and gas pipeline pre-warning of the system was analyzed and carried out in a crude oil pipeline.The application result shows that the system can monitor artificial excavation near the pipeline,and effectively differentiate the artificial excavation and interference signals by means of multi-parameter pattern recognition algorithm.
