针对城市电缆或通信光缆经常遭受市政建设带来的外力破坏问题,提出一种基于光传感技术的电力管道光缆防外破监测方法。分析研究了监测系统原理与架构,利用振动装置在光缆通道上方模拟试验,并对现场数据进行了分析验证,现场实验外破定位精度小于±100 m,可明显发现施工信号频率及其倍频特征。结果表明,基于光传感技术的电力管道光缆防外破监测系统可实现外破振动信号的监测与识别,现场应用效果较好。

In view of the problem that urban cables or communication cables are often damaged by external forces caused by municipal construction,a monitoring method based on optical sensing technology for power pipeline optical cables is proposed in this paper.The principle and architecture of the monitoring system are analyzed and studied.The vibration device is used to simulate the test above the optical cable channel,and the field data are analyzed and verified.The results show that the power pipeline optical cable anti-damage monitoring system based on optical sensing technology can realize the monitoring and identification of the external damage vibration signal,and the field application effect is better.
