铁路沿线光电缆温度智能监测系统

Temperature Monitoring System of Optical Cable Along Railway

为防止铁路沿线光电缆因异常温升导致断缆或损伤的情况发生,利用铁路沿线既有的通信光缆,结合布里渊光时域反射计技术,对通信光缆沿线的温度变化进行测量、定位并及时进行报警,实现了铁路光电缆温度环境的分布式、全天候实时自动监测定位功能。

To avoid the occurrence of broken or fractured cable caused by abnormal temperament rise,based on existing communication optical cable along the railway,and the Brillouin optical time domain reflectometry,or BOTDR,the temperament changes of the communication optical cable would be measured and positioned and alarms would be give off timely.Thus,a distributed and real-time automatic cable temperature monitoring in all weather can be achieved.
