直升机电力巡检中的电力线测距方法

直升机电力线巡检的一项重要内容是测量电力线与下方地物的距离,判断电力线附近的地物是否达到危险的高度或位置(即电力线测距),确保线路运行安全。本文在直升机巡检的背景下,结合电力线测距的特点,介绍了电力线测距的基本原理,提出了电力线空间坐标获取和基于铅垂线轨迹法(VLL)直接求取电力线断面高程的方法,并给出了电力线测距数据处理流程,最后通过实验证明了该方法的有效性和可行性。

Power line distance measurement method in helicopter power line inspection

One of the impartant tasks in the helicopter inspection is surveying the distance between the power line and the surface features below in order to determine whether the height or location is dangerous(i.e.power line survey) to ensure the safe operation.This article taking helicopter inspection as the background,combined with the characteristics of power line survey,introduced the basic principles,analyzed two key technologies involved,proposed the method of getting the space coordinates of the power line and the matching method-Vertical Line Locus method(VLL) to strike a power line cross-section elevation directly,and gave the data processing,Finally,experimental results showed that the method was effective and feasible.
