机载LiDAR测量技术在输电运维中的应用

The application of transmission and maintenance based on airborne LiDAR measurement technology

输电线路运维是输电管理的重要环节,传统输电线路巡检依靠人巡为主机巡为辅的作业模式,其巡线测量精度、准确率、时间周期长难以保证。当前机巡作业在一定程度上缓解了运维压力,解决输电线路通道大致情况的检查,但仍未实现树障的精确巡检,机载LiDAR技术的出现使得输电运维模式得以改善,其作为新兴测量手段使输电通道危险点精准测量检测成为可能。文章探讨了传统输电线路运维存在的工作效率、安全度及作业强度等问题,结合机载LiDAR的特点研究该技术在电力工程勘测成图及输电通道危险点检测分析领域技术实现流程与应用情况,以及激光点云数据快速处理与分类,实现对输电通道环境的及飞及测,探讨进一步提升运维应急抢险反应速度和隐患判定的精度,以减少运维人工巡线的投入,提高运维效率。

Transmission line operation and maintenance is an important link of transmission management, the traditional power line patrol auxiliary depends on the operation model of the host, the inspection precision, line measurement accuracy, a long period of time is difficult to guarantee the operation;patrol aircraft to ease the operation pressure to a certain extent, solve the transmission line channel is approximately to check the situation, but yet to achieve accurate inspection tree barrier, airborne LiDAR technology makes the transmission operation mode can be improved, as a new measure to make precise measurement of the dangerous point of transmission channels as possible, this paper discusses the problems of traditional transmission line operation and maintenance work efficiency, safety and work intensity, combined with the characteristics of the airborne LiDAR technology in the electric power engineering survey into danger point diagram and transmission channel detection and analysis technology realization process and application, research on laser point cloud data According to the rapid processing and classification ,we can realize the transmission channel environment and flight and measurement, further improve the speed of operation and emergency response and the accuracy of hidden danger determination, so as to reduce the investment in operation and maintenance, and improve operation and maintenance efficiency.
