Power transmission line patrol flight avoidance device and multi-rotor patrol unmanned aerial vehicle

Abstract

The invention is suitable for the field of communication and provides a power transmission line patrol flight avoidance device and a multi-rotor patrol unmanned aerial vehicle. The device comprises an ultrasonic sensor; a distance measuring unit for calculating the distance between the flight avoidance device and barriers according to reception time of reflected electrical signals; a flight control unit for determining the flight state according to the distance and generating a corresponding flight control instruction; and a flight power unit for executing the corresponding flight state according to the flight control instruction. The power transmission line patrol flight avoidance device realizes distance measurement of the barriers in six directions of the unmanned aerial vehicle respectively, calculates the distance between the flight avoidance device and the barriers according to the echo reception time and controls electronic speed adjusters on engine arms to adjust the rotation speeds of motors respectively, so that lift force of each engine arm is adjusted and emergency obstacle avoidance can be realized; the six-rotor unmanned aerial vehicle is controlled to hover, move back, rotate or fly to the left or right, thereby protecting the unmanned aerial vehicle from bumping the barriers, which leads to out-of-control crash of the airplane.

Description

technical field [0001] The invention belongs to the field of communications, and in particular relates to a power transmission line patrol flight avoidance device and a multi-rotor line patrol drone. Background technique [0002] In recent years, the sustained and rapid development of my country's national economy has put forward higher and higher requirements for the electric power industry. At present, my country has formed six inter-provincial power grids in North China, Northeast China, Central China, Northwest China and South China, with more than 700,000 km of transmission lines. However, due to my country's vast territory, complex terrain, few plains, many hills and mountainous areas, complex meteorological conditions, and unstable quality of porcelain insulators, in order to provide safe and reliable power supply, the automation and modernization of line inspection maintenance has increasingly shown its urgency. [0003] At present, one is to use the method of limit...
