Transmission line inspection system based on multi-rotor unmanned aircraft

Abstract

The invention discloses a transmission line inspection system based on a multi-rotor unmanned aircraft, which comprises the multi-rotor unmanned aircraft and a ground support system, wherein the multi-rotor unmanned aircraft comprises an aircraft body, an airborne flight control system, an airborne task system and an airborne power supply for supplying power to all the electronic devices; the aircraft body comprises a body, an undercarriage fixedly connected below the body, and a plurality of rotor components which are symmetrically distributed on the periphery of the body; the airborne flight control system comprises a flight navigation and control part, a transmission line anti-collision warning and control part, and an airborne end used for remotely controlling a telemetry data chain; the airborne task system comprises a damping nacelle, an image acquiring device arranged on the damping nacelle, and the airborne end for a wireless image transmission chain; and the ground support system comprises a ground end for remotely controlling the telemetry data chain, a flight monitoring system, the ground end for a wireless image transmission chain, and an image monitoring system. The transmission line inspection system has a reasonable structure, is easily realized, and has high engineering application value.

Description

technical field [0001] The invention relates to a power transmission line inspection system based on a multi-rotor unmanned aerial vehicle, which belongs to the multi-technical interdisciplinary fields of electric power, aviation, and control. The proposal and application of the present invention provide a highly reliable, low-risk, high-efficiency, and low-cost intelligent technical means for short- and medium-distance inspection and detection of power transmission lines, and adapt to the development needs of national smart grid technology. Background technique [0002] Transmission lines have the characteristics of wide distribution, large coverage, complex terrain and harsh natural environment. Since the power wires, ground wires, towers and their accessories are exposed to the wild for a long time, they will be subjected to continuous mechanical tension, various weather phenomena (wind and sun, rain, snow, frost, lightning flashover, etc.), material aging, animal or man-...

AI Technical Summary

Problems solved by technology

[0009] Taken together, it can be seen that in recent years, the research on electric power inspection based on aviation aircraft has rarely disclosed technical details, and there are common problems such as high system complexity, strong control professionalism, low inspection efficiency, high operating costs and risks, and intelligent Low level and other deficiencies (four-rotor UAV is relatively good); especially in terms of the reliability of the aircraft itself and the anti-collision protection of the line safety, there is a lack of practical and effective means
