摘　　要：针对城区电缆管廊因施工受损、盗窃等潜在外力破坏问题,研究基于物联网技术和视频监控的管廊防破坏监测分析策略。根据光纤传感技术原理,利用瑞利散射光探测光纤中的扰动信息,判断电缆是否受到外部破坏威胁,同时利用脉冲返回时间,精准定位外界干扰的位置。应用结果表明,系统可实现外力破坏的定位和预警,为线路安全可靠运行提供有力保障。In view of the potential external damage problems of urban cable pipe corridors due to construction damage,theft,etc.,it describes the monitoring and analysis strategies of pipe corridors based on Internet of Things technology and video surveillance.According to the principle of optical fiber sensing technology,Rayleigh scattered light is used to detect the disturbance information in the optical fiber to determine whether it is threatened by external damage.The pulse return time is used to accurately locate the location of external interference.Through the research and application of the cable pipe gallery anti-damage monitoring system,the location and early warning of external damage can be realized,which provides a strong guarantee for the safe and reliable operation of the line.
