Description

technical field [0001] The invention relates to the technical field of electric power inspection, and relates to an electric inspection drone, in particular to an auxiliary mechanical arm for an electric inspection drone and a control system thereof. Background technique [0002] In the power system, the high-voltage overhead transmission line is the aorta of regional power transmission, and the maintenance of the high-voltage overhead line is the basic technical guarantee to ensure the safe operation of the high-voltage transmission network. The maintenance work of high-voltage overhead transmission lines is used to ensure the safe, stable and efficient operation of the power grid, but the transmission line equipment is exposed to the outdoors for a long time, and after long-term operation of wires, lightning conductors, insulators, and fittings, due to the long-term effects of various factors, Falling towers, wear, broken strands, rust, overheating, etc., insulators may be...

Problems solved by technology

However, the device itself only has the function of removing foreign matter, and does not have the ability of power inspection and zero value detection

At the same time, the bottom plate, column, frame and motor support of the device are all made of hollow carbon fiber boards. Without insulation treatment, the body is easily broken down by high voltage.

[0007] The Chinese patent document with the publication number CN109941436A "A UAV capable of live-line operation and maintenance of power line faults" uses multiple systems such as multi-point image acquisition, 3D visualized multi-dimensional control, GPS and Beidou positioning to realize ground personnel Precise control of the robotic arm for drone flight and line fault elimination, rapid inspection and accurate positioning of power line equipment faults, but the device still does not have the functions of electrical inspection and zero value detection

At the same time, the power supply device included in the system, which can use the electromagnetic field around the power line for wireless charging, may also have an impact on the drone's own circuit.

[0008] The Chinese patent document "A UAV-Based Contact Electroscope System and Its Working Method" with the publication number CN109270329A integrates UAV technology and traditional electroscope systems, and uses sensors to collect signals from contact electroscopes and Using wireless transmission technology to transmit the signal to the ground staff, the maintenance personnel can control the drone on the ground, reducing the time-consuming power inspection, but the system itself does not have foreign object removal and zero value detection functions

At the same time, the device has obvious deficiencies in the design of the photoacoustic signal acquisition board and the electromagnetic interference suppression design of the ARM microcontroller
