摘要
高压输电线路跨度较大,并且沿线地理条件复杂,给设计工作增加了难度。无人机(Unmanned Aerial Vehicle,UAV)在工程测绘、电力巡检等方面应用广泛,利用无人机搭载激光雷达,对高压输电线路的沿线地理信息进行采集,并使用特定的软件利用采集数据制作三维图,可以为设计人员直观了解输电线路沿线情况和优化设计方案提供必要的支持。基于此,以某220 kV高压输电线路为例,概述无人机校验方案和航线方案的设计内容、激光点云数据处理以及DEM、DOM的生成方法,从工程路径与排位优化方面,总结利用无人机激光雷达技术优化高压输电线路设计的效果,为后续工程施工提供支持。
The large span of high-voltage transmission lines and the complex geographical conditions along the lines increase the difficulty of design.Unmanned Aerial Vehicle(UAV)is applied widely in engineering surveying and mapping,electric inspection,etc.,using UAVs laser radar,for high voltage transmission line along the acquisition of geographic information data and the use of specific software using the collected data to produce three dimensional figure,intuitive to designers understand the situation along the transmission line and the optimization design program provides the necessary support.Taking a 220 kV high-voltage transmission line as an example,this paper firstly summarizes the design content of UAV verification scheme and route scheme,as well as the method of laser point cloud data processing and generation of DEM and DOM.Then,it summarizes the effect of UAV lidar technology in optimizing the design of high-voltage transmission line from the aspects of engineering path and scheduling optimization.It provides support for subsequent engineering construction.
