An intelligent and autonomous flight inspection system and method for overhead high-voltage lines along the conductor

Abstract

The invention discloses an intelligent autonomous flight inspection system and method for an overhead high-voltage line, including a ground control station, a laser radar, a laser radar data processing module, and a multi-rotor drone. The laser radar and the laser radar data processing module are all set in On the multi-rotor drone, the laser radar is used to collect the angle and distance information of the high-voltage line relative to the multi-rotor drone, and the laser radar data processing module transmits the above information to the ground control station by wireless; the motor in the multi-rotor drone The drive module controls the speed of each propeller motor in the multi-rotor UAV under the control of the UAV control center, so that the UAV maintains a fixed distance from the overhead high-voltage line and cruises along the overhead high-voltage line. The invention has the advantages of no need for personnel operation, high efficiency, multi-function, all-round intelligent monitoring and inspection of overhead high-voltage lines in the inspection process, and the like.

Description

technical field [0001] The invention relates to the technical field of inspection, and in particular to an intelligent autonomous flight inspection system and method for overhead high-voltage lines, which are suitable for detection of overhead high-voltage lines and tree barrier distances around overhead high-voltage lines. Background technique [0002] With the rapid economic development, the construction of power grids in various countries has experienced a stage of rapid development. Taking my country as an example, six major power grids across provinces and regions have been built, and the total length of transmission lines exceeds 1.15 million kilometers. Due to long-term exposure to the wild, the power line is damaged by continuous mechanical tension, lightning flashover, material aging, and human influence, such as broken strands, wear, and corrosion. It must be repaired or replaced in time. At the same time, the growth of trees in the wild may cause discharge of powe...

Problems solved by technology

However, most drones use wireless remote control to control the flight, and the drone must be controlled within the operator's field of vision, the flight range is limited, and autonomous flight cannot be achieved

In addition, drones use wireless remote control to control flight in the environment of strong magnetic field interference such as overhead high-voltage lines, which is prone to operating errors or equipment failures, resulting in equipment damage.
