电力光缆自动监测系统设计方案

介绍了电力光缆自动监测系统的硬件设计包括硬件组成、工作原理和主要功能以及软件设计包括程控光开关的控制和模块的控制流程；提出了运用电力光缆自动监测系统的关键技术，即自动测试和手动测试的选取，相关参数的设置及故障点地理位置的精确定位。通过电力光缆自动监测系统可获取光纤长度、平均损耗、反射损耗、熔接损耗等相关数据并判断事故点与测试原点间的距离，实现故障点的精确定位，大大缩短了修复故障光缆的时间。

Design Scheme of Automatic Monitoring System for Optical Fiber Cable

This paper introduces hardware design of automatic monitoring system for optical fiber cable,such as hardware components,operating principle,major functions,as well as software components,including control of program control optical switch and control flow of modules.It proposes to utilize key techniques of automatic monitoring system,viz.selection between automatic test and manual test,setting of relevant parameters,precise localization of fault point.By means of automatic monitoring system,length of optical fiber cable,average loss,reflection loss,fusion loss are obtained and distance between accident point and test point is determined.Hence precise localization of accident point is achieved and cable repair time is greatly shortened.
