Automatic photography control device for power line inspection unmanned aerial vehicle, and control method thereof

Abstract

The invention discloses an automatic photography control device for a power line inspection unmanned aerial vehicle, and a control method thereof. The automatic photography control device is fixed on metal structure at the front end of an unmanned aerial vehicle body and located above a detection head. The automatic photography control device mainly comprises a control circuit and a battery. The control circuit and the battery are disposed in a box. The control circuit comprises a single-chip microcomputer, a servo steering engine, a wireless receiver, an LCD (liquid crystal display), keys, a camera photography control module, a power management module, and a battery. The single-chip microcomputer is respectively connected with the servo steering engine, the wireless receiver, the LCD, the keys, the camera photography control module, the power management module and the battery. The battery is further connected with the power management module. The automatic photography control device is obtained according to experiments and practical needs in power line inspection with the unmanned aerial vehicle, and allows the unmanned aerial vehicle to take photos efficiently, quickly and simply during power line section.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle power inspection, and in particular relates to an automatic photographing control device and control method of an electric line inspection unmanned aerial vehicle. Background technique [0002] The transmission lines are distributed in many areas, the terrain is complex, and the natural environment is harsh. The power lines and towers have been exposed to the wild for a long time. Due to the influence of the external environment, damage such as broken strands, wear, and corrosion must be repaired or replaced in time. Regularly check the operation of transmission lines, eliminate hidden dangers in time, and ensure power safety. Traditional manual line inspection has a heavy workload, and there are many difficulties in line inspection in complex environments such as mountains and rivers. [0003] UAV line inspection can effectively solve these problems. UAV line inspection mainly refers to t...
