Traditional power line inspection process is that the staffs have to go to the scenes for inspecting lines, the inspected objects mainly cover facilities, towers, wires, transformers, insulators, cross arms, disconnecting links and other equipment, and the inspection information shall be recorded by means of paper medium and then manually entered to the computer. Therefore, the inspection is always subject to human factors, shall endanger the life and safety of line selecting workers in hazardous locations; moreover, manual entry faces large volumes of data and the data manual entry process is error-prone; furthermore, it is impossible to conduct effective management targeted at whether the staff has made in-place inspections, once the inspection quality can not be guaranteed, the safety situations of lines can not be ensured accordingly, leaving safety risks. So what kind of effective measures should be taken is a challenge placed in front of the power sector.
With the rapid economic development, the demand for energy is soaring, so ultra-high pressure-high-capacity power lines are substantially expanded. Line corridors need pass through a variety of complex geographical environment, to reach reservoirs, lakes, steep mountains, etc., all of which bring a lot of difficulties for the detection of power lines. Especially with regard to power lines pass through the primeval forest fringe areas, high altitude, snow-covered areas, move along the areas with the geological disasters as more frequent landslides, debris flows, etc., and most areas are accompanied by high mountains and steep slopes, as well as extremely underdeveloped transport and communications, so how to resolve the day-to-day detection of power lines and improve the detection accuracy and efficiency has become a major problem that plagues the power industry.
