摘　　要：介绍了基于光散射的分布式光纤温度传感网络的研究现状和发展趋势,主要阐述了基于瑞利散射、喇曼散射和布里渊效应的分布式光纤传感器的工作原理。在此基础上重点介绍了其在高压电缆、电力线沿线温度测量中的应用情况,探讨了传感光电缆替代原有的电缆和光缆,使光通信、电力传输、传感三合一的趋势。The research present status and development of distributed optical fiber temperature sensing network based on light scattering was described. The distributed optical fiber temperature sensors based on Rayleigh scattering, Raman scattering and Brillouin scattering were mainly represented. And the application of optical fiber sensor in high voltage cables and eleetrieal power line supervision were mainly introduced. The sensing light-electrical cable substituted for original electrical cable and optical fiber cable was discussed. The developing three-in-one trend of optical communication, power transmission and sensor was also analyzed.
