UAV (unmanned aerial vehicle) landing detection device for dynamically monitoring ground obstacle

Abstract

The invention relates to a UAV (unmanned aerial vehicle) landing detection device for dynamically monitoring ground obstacles. The UAV landing detection device for dynamically monitoring the ground obstacles is characterized in that the UAV landing detection device comprises a mounting plate; four corners of the bottom of the mounting plate are welded with a sliding sleeve; a partition is welded on the inner side of the sliding sleeve; a supporting slider is slidingly embedded in the inner side of the sliding sleeve and below the partition. The UAV landing detection device for dynamically monitoring the ground obstacles has the advantages that with a second ranging laser radar arranged in the center of the bottom of a turntable, the height of the UAV in the vertical direction can be detected; with a first ranging laser radar in inclined arrangement on the outer side of the turntable, rotation detection of the landing surface of the UAV is carried out, and the first ranging laser radarand the second ranging laser radar can transfer data to a controller for analysis; when the turntable rotates for one week and detects an obstacle, the controller controls the UAV to keep hovering atthe current height, and when the height is lower than the rated value, the controller can control the UAV to rise to a specified height; consequently, the structure can effectively prevent the UAV from coming into contact with the obstacle when the UAV is landing, thereby improving the flight safety of the UAV.

Description

technical field [0001] The present invention relates to the technical field of UAV accessories, and more specifically, relates to a UAV landing detection device for dynamically monitoring ground obstacles. 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. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned paraglider etc. Compared with manned aircraft, it has the advantages of small size, low cost, convenient use, low requirements for combat environment, and strong battlefield survivability. [0003] However, the existing drones do not have an obstacle detection mechanism when they land, so they cannot effectively detect whether t...

AI Technical Summary

Problems solved by technology

[0003] However, the existing drones do not have an internal obstacle detection mechanism when landing, and cannot effectively detect whether there are obstacles on the ground. When there are obstacles on the landing surface, the drone will directly collide with the obstacle when it lands. , it is easy to cause damage to the UAV, and the safety is poor. Secondly, the existing UAV does not have a landing buffer structure inside. When the UAV directly touches the ground, it is easy to cause the precision components inside the UAV to be impacted. damage, poor protection
