摘　　要：分析了OPGW光缆监测在电力系统光通信中的重要意义,给出了利用布里渊散射进行温度和应变分布式传感的机理。针对OPGW光缆铺设线路长,易受环境因素影响的特点,提出了将BOTDR技术应用于光缆监测中的方法,并对该技术的基本原理以及温度和应变测量的传感方案进行分析。给出了一种基于BOTDR的OPGW光缆自动监测方法,介绍了该方法的原理,并对该方法的系统结构、特点以及存在的问题进行了阐述。This paper analyses the importance of OPGW monitoring in power commtmication system, discusses the mecha- nism of temperature and strain distributed sensing using brillouin scattering. Considering OPGW features of long laying and vulnerable to environmental factors, the paper put forward a method of applying BOTDR technology for optical cable monitoring. It analyses the basic principle of this technology and the sensing solution of measuring the temperature and strain. A automatic monitoring method for OPGW cable based on the BOTDR is introduced, and the principle, system structure as well as the characteristics of the method are also discussed in the paper.
