Method for defect searching of power transmission lines of multi-rotor unmanned aerial vehicles

Abstract

A method for defect searching of a power transmission lines of multi-rotor unmanned aerial vehicles is characterized in that two unmanned aerial vehicles are adopted to perform flight operation simultaneously, one unmanned aerial vehicle is an operation unmanned aerial vehicle for normal tour, and the other unmanned aerial vehicle is positioned over or at the horizontal orientation of the operation unmanned aerial vehicle and an observed object. When prime lenses are used for the unmanned aerial vehicles, the space distance of the unmanned aerial vehicles should be kept between 3 m and 12 m; and when zoom lenses are used for the unmanned aerial vehicles, the space distance of the zoom lenses should be maintained between 8-20 m. The method has the advantages that through repeated tests, we find that the endurance of the observing unmanned aerial vehicle is more than that of the operation unmanned aerial vehicle by more than three minutes; after the operation unmanned aerial vehicle takes off and is close to the line stage, the observing unmanned aerial vehicle should be above the operation unmanned aerial vehicle and a line to perform observation, and after approaching the line, the observing unmanned aerial vehicle should be at the conversion orientation so as to meet the observation requirements of the operation unmanned aerial vehicle in other orientations.

Description

technical field [0001] The invention belongs to the electric power industry, and relates to an application method of a multi-rotor unmanned aerial vehicle for circuit inspection and a two-position multi-rotor unmanned aerial vehicle for finding defects in power transmission lines and breaking regulations by external force. Background technique [0002] At present, with the development of science and technology and the popularization of multi-rotor UAV technology, more and more power supply companies use multi-rotor UAVs for various inspections and inspections on the line. [0003] However, in the process of using multi-rotor drones for operations, we found that in some cases, the observation target is far away from the drone operator, and the terrain conditions do not allow the drone operator to observe from another angle. When the operator is operating the drone, there will be many visual blind spots or visual errors, which will cause the drone operator to misjudge the dist...

Problems solved by technology

[0003] However, in the process of using multi-rotor drones for operations, we found that in some cases, the observation target is far away from the drone operator, and the terrain conditions do not allow the drone operator to observe from another angle. When the operator is operating the drone, there will be many visual blind spots or visual errors, which will cause the drone operator to misjudge the distance between the target and the drone when operating the drone, and cannot be accurate and timely. Adjust the direction and attitude of the UAV, if it is light, it will cause the UAV to fail to complete the corresponding task, if it is serious, it will cause the UAV to accidentally touch the live line, or crash into other obstacles, resulting in a crash, and even affect the safety of the power grid and surrounding personnel
