Power transmission line inspection system based on fixed-wing unmanned aerial vehicle

Abstract

The invention discloses a power transmission line inspection system based on a fixed-wing unmanned aerial vehicle. The power transmission line inspection system based on the fixed-wing unmanned aerial vehicle comprises a ground station and a fixed-wing unmanned aerial vehicle, wherein the ground station comprises a ground control system, an image receiving system, and a data processing system, the fixed-wing unmanned aerial vehicle comprises an unmanned aerial vehicle body, a remote sensing monitoring device, a real-time detection device, an image transmission system, an instruction receiving system, a power system, and a flying control system. The remote sensing monitoring device is used for collecting image information in an area of a power transmission line at a fixed time or a fixed distance or a fixed spot, the real-time detection device is used for collecting information in the area of the power transmission line in real time, and the remote sensing monitoring device and the real-time detection device are arranged on the unmanned aerial vehicle body in a front-and-back adjacent and direct-to-ground mode. The power transmission line inspection system based on the fixed-wing unmanned aerial vehicle is capable of conducting periodical or emergent macroscopic inspections on the power transmission line and accessory equipment of the power transmission line, so that labor intensity of manual power transmission line inspection work is greatly reduced, and power transmission line inspection efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power transmission line inspection system based on a fixed-wing unmanned aerial vehicle. Background technique [0002] In my country, the transmission lines of the power grid have the following characteristics: 1. The terrain and offline environment of the transmission lines are relatively complex; rapid growth or the emergence of illegal buildings). 2. The distribution of transmission lines is wide, the coverage is large, and the natural environment is harsh; especially for some transmission lines distributed in mountainous areas and transmission lines crossing large rivers and rivers, because the areas where they are located are particularly prone to ice disasters, floods, earthquakes, etc. disasters, landslides, mudslides and many other natural disasters, resulting in a significant reduction in the safety factor of these lines. In view of this, the power sector has an extremel...

2. The distribution of transmission lines is wide, the coverage is large, and the natural environment is harsh; especially for some transmission lines distributed in mountainous areas and transmission lines crossing large rivers and rivers, because the areas where they are located are particularly prone to ice disasters, floods, earthquakes, etc. Disasters, landslides, mudslides and many other natural disasters have greatly reduced the safety factor of these lines

However, the unmanned helicopter in the above scheme has insufficient inherent stability and high professional requirements for manual operation. In order to meet the requirements of payload and wind resistance performance, it must have a considerable scale and quality; Line equipment, surrounding environment and ground personnel are potentially harmful, and the operation risk is also high, resulting in very limited potential for comprehensive application and promotion

[0006] 2. The invention patent of "a flying robot for detecting insulators of transmission lines" with the application number of 200810224172.1. This patent is specially used for the detection of insulators of transmission lines, and does not involve the detection of large-scale transmission line corridors. Therefore, It cannot solve the problem of difficult inspection of transmission lines in areas prone to natural disasters such as ice disasters, floods, earthquakes, landslides, or mud-rock flows

[0007] 3. The invention patent of "power transmission line inspection system based on multi-rotor unmanned aerial vehicle" with application number 201110055423.X, which can be used for transmission line inspection, but the image transmission distance in this patent is relatively short, only It can carry out small-scale inspections, but cannot complete one-time long-distance and large-scale inspections of overhead lines. Moreover, it does not have the functions of real-time return of videos and photos, and comparison and analysis of the actual situation of the lines.

[0008] It can be seen that the current transmission line inspection schemes generally have deficiencies such as high system complexity, strong control expertise, high operating costs and risks, and low intelligence level, and the existing UAV inspection system task load Shortcomings such as low flight time, short voyage time, small single inspection range, etc., and it is impossible to achieve real-time macro viewing of video images and timely acquisition of high-resolution photo image information of corresponding parts
