Problems solved by technology

[0005] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide an automatic airport and control method for unmanned aerial vehicles, which is used to solve the problem that the development of the ground handling system of the unmanned aerial vehicle in the prior art lags behind the development of the unmanned aerial vehicle itself. The degree of automation is low, and manual guarding is required; even in airports equipped with aprons, drones often have low positioning accuracy when landing, and there are large deviations in landing positions or even landing outside the apron, which indirectly leads to the entire shutdown The size of the ping needs to be made very large; in addition, ground handling operations also require a lot of manual participation to complete, such as manually replacing the battery, because currently drones generally need to replace the battery in less than half an hour. The problem is that the drones are large, and the drones are operated outdoors, and the working environment of the operators is harsh

Embodiment 1

[0127] Embodiment one, as figure 2 , image 3 As shown, the transmission mechanism of the split hatch 1 is driven by a synchronous belt. The main principle is that the motor drives the synchronous pulley to drive the synchronous belt to move. The synchronous belt realizes the opening and closing of the left and right hatches through the connecting block. Guide rail for guidance;

[0128] The main components include: left hatch, right hatch, motor, synchronous pulley, synchronous belt, transmission shaft, guide rail slider, connecting block, sliding plate and other basic components;

[0129] The action is: the motor drives the drive shaft to rotate through the synchronous belt, and the drive shaft drives the synchronous pulleys at both ends to drive the two left and right synchronous belts to move. Synchronous movement in the same direction, the left connecting plate is connected through the left sliding plate and drives the left hatch to move, similarly, the right connectin...

Embodiment 2

[0131] Embodiment two, such as Figure 4 As shown, the transmission mechanism of the split hatch 1 adopts a rack-and-pinion drive mode. The main principle is that the motor drives the gear to rotate, and the gear and the rack are meshed to drive to realize linear motion. The rack is fixed on the hatch, so that the hatch The switching action is realized, and the movement is guided by the linear guide rail slider. The main components include: left hatch, right hatch, left motor, left gear, left rack, right motor, right gear, right rack, guide rail , slider and other basic components;

[0132] The action is: the left motor is fixedly installed on the airport equipment, drives the left gear to rotate, the left gear meshes with the left rack to drive the left rack to move in a straight line, and the left rack is fixed on the left cabin door, so that the left cabin door realizes the opening and closing action ; The action of the right cabin door is the same as that of the left cabi...

Embodiment 3

[0133] Embodiment three, as Figure 12 As shown, the shrapnel-type claws do not have motors, gears, rotating shafts and other related parts for opening and closing the claws. Instead, the claws are made into shrapnel forms. The claws enter the battery, and the battery props up the claws until the front part of the claw is buckled. Insert the end face of the battery, and the claws move back to pull out the battery.

Abstract

The invention provides a control method for an unmanned aerial vehicle automatic airport. The landing method comprises the following operation steps that A) the unmanned aerial vehicle acquires real-time position information of the automatic airport; B) approaching of the unmanned aerial vehicle in the air is carried out; C) positioning of the unmanned aerial vehicle is carried out, and PID control is performed through a horizontal position; D) the height of the unmanned aerial vehicle is gradually reduced; E) free falling landing of the unmanned aerial vehicle is carried out: power is cut offat a height 5-10cm away from the automatic airport platform to realize free falling landing; and F) automatic airport centering adjustment is carried out: the automatic airport performs centering adjustment on the landing position of the unmanned aerial vehicle. Automatic and accurate landing and storage of the unmanned aerial vehicle on an automatic airport are realized; the unmanned aerial vehicle has a landing position real-time adjusting function, the landing precision of the unmanned aerial vehicle is guaranteed to be about 10 cm, a battery can be automatically replaced, the taking-off and landing requirements of the unmanned aerial vehicle in severe weather such as rain, snow and the like can be met, the application field of the unmanned aerial vehicle is greatly expanded, the workload of operators is reduced, and airport equipment is compact in size.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an automatic airport for an unmanned aerial vehicle and a control method, which are suitable for precise landing of an unmanned aerial vehicle on an automatic airport and related operations after landing. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, mi...
