摘　　要：为提升电力通信光缆线路故障定位性能,设计基于GIS技术的电力通信光缆线路故障智能定位系统。搭建系统硬件网络架构,描述光时域反射计的内部结构,分析光时域反射计检测过程的示意图,利用公式计算光缆线路长度,得到实测的OTDR曲线。软件设计方面,将通信光缆线路遥感数据以及其他信息经过变换、拼接、矢量化处理后完成GIS地图数字化转换,根据这些数据进行故障智能定位算法设计。测试结果表明:设计系统的故障定位结果与实际值间偏差小,获得了电力通信光缆线路故障高精度定位结果。In order to improve the fault location performance of power communication optical cable line,an intelligent fault location system of power communication optical cable line based on GIS technology is designed.It builds the system hardware network architecture,describes the internal structure of the optical time domain reflectometer,analyzes the schematic diagram of the detection process of the optical time domain reflectometer,uses the formula to calculate the optical cable line length,and obtains the measured OTDR curve.In terms of software design,the remote sensing data of communication optical cable lines and other information are transformed,spliced and vectorized,and then the digital transformation of GIS map is completed.According to these data,the intelligent fault location algorithm is designed.The test results show that the deviation between the fault location results of the designed system and the actual values is small,and the high-precision fault location results of power communication optical cable lines are obtained.
