Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] The invention provides an automatic landing and recovery system for unmanned autonomous aircraft under complex dynamic turbulence conditions, which solves three key problems: one is that the unmanned aerial vehicle must autonomously identify the landing platform and move to the platform autonomously; The environment in which the platform moves is relatively bumpy, and the platform needs to be able to maintain a static attitude to a certain extent, without shaking with vehicles, ships, etc., or to make autonomous adjustments according to the attitude of the drone to fit the attitude angle of the drone when it lands. , to reduce the impact on the landing platform in a dynamic environment; the third is to fix the UAV after it has docked, so as not to fall with the movement of vehicles and other carriers.

[0028] For the above key issues, see figure 1...

Abstract

The invention discloses an automatic landing and recovery system for an unmanned autonomous aircraft under complex dynamic turbulence conditions, which utilizes a binocular camera installed on the UAV to locate the landing platform, and guides the UAV to land on the landing platform; A landing platform with adjustable attitude is installed on it, the carrier detects the attitude of the UAV, and adjusts the attitude of the landing platform based on the attitude of the UAV, so that the attitude of the landing platform matches the attitude of the UAV when it lands, making the landing process more stable and reliable. The limitation of the traditional UAV free landing technology on the stable state of the landing platform is removed; the invention further uses electromagnets to fix the landed UAV so that it can be docked firmly and will not fall with the movement of the landing platform, and can be moved at any time By controlling the electromagnet to release the UAV to take off, it solves the problem that it is difficult for the UAV to move stably with the carrier after landing.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and relates to an automatic landing and recovery system for unmanned autonomous aerial vehicles under complex dynamic turbulence conditions. Background technique [0002] Unmanned aircraft, referred to as UAV, or UAV (unmanned aerial vehicle) or UAS (unmanned aircraft system), is an unmanned aircraft that is controlled by radio remote control equipment and autonomous program control devices. Compared with manned aircraft, the application of drones can effectively expand the scope of activities and improve working hours, and has great application space in the fields of military, scientific research, government, commercial activities, and personal consumer goods. [0003] However, most unmanned aerial vehicles have the problem of insufficient endurance, and the short flight time has become an obstacle to their large-scale application. Therefore, it is very meaningful to develop a UAV landin...
