Overhead high-voltage line intelligent autonomous flight tour inspection system and method along wires

Abstract

The invention discloses an overhead high-voltage line intelligent autonomous flight tour inspection system and method along wires. The system comprises a ground control station, laser radar, a laser radar data processing module and a multi-rotor unmanned aerial vehicle, the laser radar and the laser radar data processing module are both arranged on the multi-rotor unmanned aerial vehicle, the laser radar is used for acquiring information of the angle and the distance of a high-voltage line relative to the multi-rotor unmanned aerial vehicle, the laser radar data processing module transmits theabove information to the ground control station in a wireless mode, a motor driving module of the multi-rotor unmanned aerial vehicle performs rotating speed control on propeller motors in the multi-rotor unmanned aerial vehicle under the control of an unmanned aerial vehicle control center, the unmanned aerial vehicle and the overhead high-voltage line maintain a fixed distance, and the unmannedaerial vehicle performs cruise flight along the overhead high-voltage line. According to the system and method, in the tour inspection process, personnel operation is avoided, and high-efficiency, multifunctional and omnibearing intelligent overhead high-voltage line monitoring tour inspection can be realized.

Description

Technical field [0001] The invention relates to the technical field of inspections, in particular to an overhead high-voltage line intelligent autonomous flight inspection system and method along a wire, which is suitable for the detection of the situation of the overhead high-voltage line and the distance of tree barriers around the overhead high-voltage line. Background technique [0002] With the rapid economic development, the construction of power grids in various countries has gone through a stage of rapid development. Take my country as an example. At present, six large trans-provincial power grids have been built, and the total length of transmission lines exceeds 1.15 million kilometers. Due to long-term exposure to the field, the power line is damaged by continuous mechanical tension, lightning flashover, material aging, and man-made influences such as broken strands, abrasion, and corrosion. It must be repaired or replaced in time. At the same time, the growth of trees...

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 operational errors or equipment failures, resulting in equipment damage.
