Four-rotor aircraft system of autonomous navigation power line inspection fault detection

Abstract

The invention discloses a four-rotor aircraft system of autonomous navigation power line inspection fault detection. The four-rotor aircraft system is composed of a ground upper computer, a flight control module, an ultrasonic ranging module, a transfer control module, a serial port expansion board, a GPRS communication module, a Beidou navigation module, a battery monitoring module, a camera and an image detection module. According to the system, the obstacles are avoided by using ultrasonic waves in line inspection of an aircraft, the power line fault is detected by using the camera and the image detection module, the detection result and the flight data are transmitted to the ground upper computer in real time through the GPRS communication module, the ground upper computer can also control the aircraft, the battery monitoring module monitors the electric quantity of the battery in real time in line inspection, whether the current aircraft requires to return to the charging point is predicted through calculation, and the aircraft can autonomously return to the charging point when the electric quantity is insufficient.

Description

technical field [0001] The invention belongs to the technical field of electric power line inspection, and in particular relates to a four-rotor aircraft system for self-navigation electric line inspection fault detection. Background technique [0002] With the rapid development of the national economy and the continuous expansion of the city, the power consumption of life and industry has increased sharply, and the scale of the national power grid has continued to expand. A large number of power lines require a lot of manpower, material resources, and financial resources to check to ensure the safety of electricity use. Due to its simple structure, light body weight, and relatively simple control method, the quadrotor aircraft has become a new method of line inspection in recent years by using UAVs for line inspection. Installing high-definition cameras or thermal imagers on UAVs , transmit the power line image to the ground control station, and manually observe whether th...

Problems solved by technology

If we cannot communicate with the aircraft and obtain the status information of the quadcopter regularly, we will not be able to control and calibrate the flight of the quadcopter

Once the aircraft fails or yaws, we cannot reset and adjust the state of the quadcopter through the corresponding control commands in time, which will lead to the adverse consequences of the quadcopter crashing or losing contact
