摘要
研究基于全光纤传感技术的电缆健康状态监测系统。在分析和研究后向散射分布式光纤传感原理的基础上,成功地开发出了样机系统,并将该系统应用于电力电缆隧道,监控数千米光纤沿线上电缆运行及环境状态的分布。实验结果表明,该系统可实现监测多回内嵌光纤的20km电缆线路的温度、载流量、偷盗入侵等分布状况,并对测量点进行定位。
A cable health state monitoring system based on all-fiber sensor technology is studied. By an analytical research on the backscattering distribution fiber sense theory, the prototyping system is worked out successfully and applied to power cable tunnel which supervises the distribution of kilometers of cable＇ running and environmental status along the line of fiber. The results prove that the system is able to supervise such status distribution as temperature, carrying capacity, stealing or invading of cables with embedded poly-cycle 20 km fiber, and then locate the measuring point.
