Unmanned aerial vehicle sea surface recycling and charging platform and control method

Abstract

The invention relates to an unmanned aerial vehicle sea surface recycling and charging platform which comprises a movable platform, a screw rod, a static platform and a mechanical arm; the movable platform is used for bearing the unmanned aerial vehicle; three screw rods are arranged between the movable platform and the static platform; the fixed ends of the screw rods areconnected with the static platform; the sliding blocks of the screw rods are connected with the movable platform through universal joints; the mechanical arm comprises a base, a first folding arm, a second folding arm and a third folding arm; the base is arranged in the center of the movable platform; one end of the first folding arm is hinged to the base, the other end of the first folding arm is hinged to the second folding arm, and the third folding arm is hinged to the second folding arm; the tail end of the third folding arm is provided with a motion interface; a conductive terminal is arranged on the outer side surface of the motion interface; and the motion interface is used for being inserted into the target interface of the unmanned aerial vehicle. The platform can complete autonomous recovery and charging operation, and the working time of the sea surface operation unmanned aerial vehicle is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle sea surface recovery and charging platform and a control method. Background technique [0002] UAVs operating on the sea surface have limited working hours due to endurance issues. Therefore, in order to increase operating capabilities and recover UAVs in real time, a landing charging device that can be easily placed on any sea carrier boat is needed. Due to the fluctuation of the hull (the spatial position and attitude of the hull will change), it is necessary to keep the platform horizontal and slightly change the spatial position. In terms of balance, the balance platform built with 3 steering gears is more suitable for small carrier boats. Although it can compensate for the attitude change of the landing plane, it is difficult to cope with the change of spatial position. In view of the 6-DOF parallel structure on the market (mainly...

Problems solved by technology

In terms of balance, the balance platform built with 3 steering gears is more suitable for small carrier boats. Although it can compensate for the attitude change of the landing plane, it is difficult to cope with the change of spatial position.

In view of the 6-DOF parallel structure on the market (mainly used as somatosensory game chairs and drone flight simulators on the market, etc.), since DC servo propellers are used as actuators, the number is large, and the control algorithm is too large. cumbersome

As for the charging of the aircraft, under normal circumstances, the charging of the aircraft uses a charger that can balance the charging. However, in the sea charging of drones that exist on the market, they are generally collected in one place and then processed manually, which is time-consuming. strenuous
