Abstract

The invention relates to the technical field of circuit checking, and provides a line checking method and device and a drone. The drone is in wireless communication with a ground control station, a nacelle is loaded on the drone, and a photographic device is loaded on the nacelle. The method comprises the steps of obtaining a to-be-checked line sent by the ground control station, wherein the to-be-checked line comprises multiple continuous target paths; determining a view field point of the nacelle at the current moment on to-be-checked target paths according to the information of the to-be-checked line and a flight position of the drone at the current moment when a line checking instruction sent by the ground control station is received; adjusting a deflection angle of the nacelle according to the view field point of the nacelle at the current moment to make the to-be-checked target paths continuously occur on a view field center of the photographic device. Compared with the prior art, the line checking method can automatically adjust the deflection angle of the nacelle to change the range of the view field for checking, and no man-made intervention is needed in the whole process.

Description

technical field [0001] The invention relates to the technical field of line inspection, in particular to a line inspection method, device and unmanned aerial vehicle. Background technique [0002] Line inspection is an important basis for the maintenance of high-voltage power lines, roads, oil pipelines and other lines. The traditional inspection method mainly uses the maintenance personnel to inspect the line facilities by relying on ground transportation or walking. This inspection method is easily affected by human factors, terrain factors and weather factors, etc., especially the inspection of high-voltage wires will endanger the lives of workers on the inspection line. Generally speaking, this inspection method has high labor costs and labor costs. low efficiency. [0003] In recent years, with the development of UAVs, there has been a way of using UAVs to carry sensor terminals to conduct high-altitude overlooking inspections of lines. This inspection method can rep...
