Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an autonomous line inspection method based on the UAV power system, which can effectively solve the problem of finding out the fault point in time after the power system fails in the background technology, and the existing The inspection of fault points in the power system usually adopts the method of manual inspection. Manual inspection will not only consume a lot of emergency repair time, but also has great limitations. When the environment is dark or dark, manual inspection will not be effective. the role of the problem

Abstract

The invention discloses an autonomous line patrol method for an electric system based on an unmanned aerial vehicle, and relates to the technical field of electric system patrol. The method takes theunmanned aerial vehicle as a carrying main body, and comprises a line patrol method for the electric system, under high light, by the unmanned aerial vehicle, and a line patrol method for the electricsystem, under dim light or no light, by the unmanned aerial vehicle. The autonomous line patrol method for the electric system based on the unmanned aerial vehicle is characterized in that in a patrol process of the unmanned aerial vehicle, imaging equipment generates an image, the image is remotely transmitted to a control room through an image processor and a communication base station, a supply worker searches a fault point, and the characteristics of high working efficiency, high accuracy rate and great working range are achieved; besides, for the condition with dim light and no light, thermal imaging equipment is carried on the unmanned aerial vehicle, and a temperature of a fault point is relatively prominent to achieve the purpose of continuously performing line patrol work on theelectric system in case of relatively dim light and even no light. The way improves work efficiency of processing an emergency event by a night repair team.

Description

technical field [0001] The invention relates to the technical field of power system line inspection, in particular to an autonomous line inspection method based on an unmanned aerial vehicle (UAV) power system. Background technique [0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and power consumption. Its function is to convert the primary energy in nature into electric energy through the power generation device, and then supply the electric energy to various users through power transmission, transformation and distribution. In order to realize this function, the power system also has corresponding information and control systems in various links and different levels to measure, adjust, control, protect, communicate and dispatch the production process of electric energy, so as to ensure that users obtain safe and high-quality electr...
