Obstacle monitoring device for unmanned aerial vehicle navigation

Abstract

The invention belongs to the technical field of unmanned aerial vehicle obstacle monitoring, and especially relates to an obstacle monitoring device for unmanned aerial vehicle navigation. The devicecomprises a mounting base and supporting legs screwed and fixed to the four corners of the bottom end of the mounting base; a mounting frame is fixed to the bottom end of the mounting base in a threaded connection mode, a servo motor is fixed to the inner side of the mounting frame in a threaded connection mode, the output end of the servo motor is connected with a rotary disc, a lower monitoringbase is fixedly arranged at the bottom end of the rotary disc, and a controller is fixedly arranged in the lower monitoring base. Laser ranging radars are arranged at the top and the periphery of an upper monitoring platform screwed at the top of the unmanned aerial vehicle through the mounting base; when the static unmanned aerial vehicle flies and rises, the laser ranging radars are used for monitoring the distances between obstacles over and around the unmanned aerial vehicle, the unmanned aerial vehicle is prevented from being impacted by the obstacles when flying and rising, the application range is wide, the use efficiency is high, the mounting base is in threaded connection with the unmanned aerial vehicle, dismounting and mounting are convenient, later maintenance and management are facilitated, and the use function is high.

Description

technical field [0001] The invention belongs to the technical field of UAV obstacle monitoring, and in particular relates to an obstacle monitoring device for UAV navigation. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. When recovering, it can automatically land in the same way as the common aircraft landing process, and can also be recovered by remote cont...

Problems solved by technology

Widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic jamming, but UAV is a kind of intelligent equipment, and the flight rise and fall are all controlled by people's remote control. When the flight is too high, people cannot observe the environment around the UAV in time Flying state, it is very easy for the obstacle collision to cause the UAV to crash

[0003] China Patent Network has proposed a UAV landing detection device for dynamic monitoring of ground obstacles, the publication number is CN109795705A, this patent solves the obstacle detection during the UAV descent process, but there are still obstacles when the UAV is flying The case of falling objects
