摘要
为了解决长输埋地管道非法占压、开挖引起的管道泄漏或偷油事件,提出了采用分布式光纤振动传感技术构建管道安全监测系统,依据管道通讯光缆中的冗余光纤实时监测并识别管道沿线因占压、开挖引起的振动信息并进行安全预警,并通过试验验证了该监测技术的可行性,指出该方法具有较高的振动定位精度和高实时性。
In order to solve the problem of oil leakage or stealing caused by illegal occupation and excavation,a novel distributed vibration fiber optical sensing technology is proposed to build a pipeline safety monitoring system. Based on the redundant optical fiber in the pipeline communication cable,the real-time monitoring and identification of vibration information caused by occupation and excavation along the pipeline are carried out and the safety warning is carried out. The monitoring method is verified by the test. Test result indicates that the method has high vibration positioning accuracy and high real-time performance.
