Research on the UAV-borne Intelligent Tower Base Positioning and Lofting Method
The lofting of overhead line towers in power grid engineering is mostly carried out in complex mountainous areas,and the traditional construction lofting method based on theodolite,total station and handheld differential satellite positioning equipment is labor-intensive,time-consuming and error-prone to data.In this paper,an intelligent tower base positioning and lofting method based on unmanned aerial vehicle(UAV)is proposed,which takes the UAV and laser projector as hardware,and research and develop the intelligent lofting software.Inputting the coordinates of the center pile of each tower pole in the overhead line into the intelligent lofting software platform,the system can calculate the planar coordinates of 20 lofting points for each tower pole in real time,and according to the distribution of the DEM model,surface trees,traffic lines and other obstacles,it can automatically plan the UAV lofting route,adjust the aerial height.With the UAV hovering above each lofting point,laser pointing is carried out to efficiently guide the surface personnel to quickly determine the location of the lofting point.Through multiple rounds of tests,it is shown that the UAV-borne intelligent tower base positioning and lofting system can be used to quickly and accurately complete the lofting of transmission line towers,significantly reducing the number and duration of lofting points in the traditional lofting mode,and provides effective support for the lofting of power grid construction.
