摘要

为了实现每基杆塔的光纤定位

从而更精准地实时监测光纤架空地线复合缆的运行状态

提出了一种基于分布式光纤传感技术的杆塔光纤定位方法。通过对实时监测频移数据进行分析

并结合光纤架空地线复合缆自身结构和架设特点发现

在杆塔连接位置由于金具等的连接原因

使得光纤频移变化量较档距中间更小

因而可以从差异化出发识别杆塔的位置

实现输电线路杆塔精确定位。最后通过与线路资料进行对比

验证了定位方式的可行性。

Abstract

In order to realize the optical fiber positioning for each pole tower

and monitor the running status of Optical Power Ground Wire（OPGW）more accurately

this paper presents a method of positioning fiber optic cable based on distributed optical fiber sensing technology.By analyzing the real-time monitoring frequency shift data and combining with the structure and erection of OPGW

it is found that the frequency shift of the optical fiber is smaller than that of the mid span due to the connection of the fittings.Therefore

we can identify the location of the tower from the difference and achieve the precise positioning of the transmission line tower.Finally

the feasibility of the location method is verified by referring the line information.
