[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a ship-based unmanned aerial vehicle assisted landing system and method suitable for remote water surfaces. Background Art

[0002] With the popularization and promotion of drone technology, ship-based drones are playing an increasingly important role in shipping, monitoring, military and other fields. At the same time, how to improve the accuracy and safety of ship-based drone landing is a major problem in the field of drone technology. Traditional ship-based drones need to rely on runway deceleration to achieve the landing of the drone. This method has the problems of large runway space and great damage to the landing gear of the drone. To solve the above problems, the current existing technology uses mechanical claws to achieve the recovery of ship-based drones, but this relies on complex and precise mechanical structures and protective materials with strong pressure resistance. The overall equipment is complex and costly, and the recovery accuracy will also decrease when dealing with complex marine weather conditions such as typhoons and tornadoes. For this reason, we propose a ship-based drone assisted landing system and method suitable for remote water surfaces. Summary of the invention

[0003] The object of the present invention is to provide a ship-based UAV assisted landing system and method suitable for remote water surfaces to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a ship-based UAV assisted landing system suitable for remote water surface, comprising a ship-based UAV and a base, wherein an electromagnetic adsorption component is rotatably installed on the top of the base, and a rotating connection component is rotatably installed on the bottom of the ship-based UAV, and after the electromagnetic adsorption component is powered on, the rotating connection component and the electromagnetic adsorption component attract each other, so as to realize the assisted landing of the ship-based UAV;

[0005] A pneumatic fisheye lens monitoring component is installed at the bottom of the ship-based UAV. The pneumatic fisheye lens monitoring component is located inside the rotating connection component and is coaxially arranged therewith, and the pneumatic fisheye lens monitoring component acts on the electromagnetic adsorption component.

[0006] Furthermore, the base is fixed on the hull.

[0007] Furthermore, the electromagnetic adsorption component includes an electromagnetic suction cup rotatably connected to the base through a bearing, a power supply is installed on the side wall of the electromagnetic suction cup, and a button is coaxially installed on the top of the electromagnetic suction cup, the button, the electromagnetic suction cup and the power supply are all electrically connected, and the three form a closed loop.

[0009] Furthermore, the side wall of the conical cylinder in the electromagnetic chuck forms an angle of 45° with the horizontal plane.

[0010] Furthermore, the rotating connection assembly includes a rotating drum rotatably connected to the bottom of the ship-based UAV through a bearing, the interior of the rotating drum is hollow, a driven wheel is coaxially mounted on the top outer surface of the rotating drum, a driving wheel is meshingly connected to the outer surface of the driven wheel, an air motor is mounted on the top of the driving wheel, and the starting motor is fixed to the bottom of the ship-based UAV.

[0011] Furthermore, the bottom of the drum is configured to be conical, and the outer surface of the drum cone is sleeved with a conical iron ring, the angle between the conical iron ring and the horizontal plane is 45°, and the conical iron ring is adapted to the conical cylinder on the top of the electromagnetic suction cup.

[0014] According to one aspect of the present invention, the present invention provides a working method of a ship-based UAV assisted landing system applicable to a remote water surface, comprising the following steps:

[0015] S1. When the ship-based UAV needs to land, the pneumatic motor is first started to drive the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate, thereby driving the rotating drum and the conical iron ring to rotate accordingly, so as to reduce the interference of wind and waves on the landing of the UAV;

[0016] S2. Use a fisheye wide-angle lens to capture images of the docking process and transmit them to the ship-based drone in real time. The ship-based drone continuously adjusts its flight attitude to bring the electromagnetic suction cup and the conical iron ring closer and closer.

After the electromagnetic adsorption component 3 is powered on, the rotating connection component 4 and the electromagnetic adsorption component 3 attract each other, so as to realize the auxiliary landing of the ship-based UAV 1;

[0033] A pneumatic fisheye lens monitoring component 5 is installed at the bottom of the ship-based UAV 1. The pneumatic fisheye lens monitoring component 5 is located inside the rotating connection component 4 and is coaxially arranged therewith, and the pneumatic fisheye lens monitoring component 5 acts on the electromagnetic adsorption component 3.

[0034] According to the technical solution of this embodiment, the electromagnetic adsorption component 3 includes an electromagnetic suction cup 31 rotatably connected to the base 2 through a bearing, a power supply 32 is installed on the side wall of the electromagnetic suction cup 31, and a button 33 is coaxially installed on the top of the electromagnetic suction cup 31. The button 33, the electromagnetic suction cup 31 and the power supply 32 are all electrically connected, and the three form a closed loop. When the button 33 is pressed down to form a passage, the electromagnetic suction cup 31 will be energized to generate magnetism, thereby adsorbing and fixing the rotating connection component 4.

[0035] Furthermore, the bottom end of the electromagnetic suction cup 31 is configured as a cylinder, and the top end is configured as a cone, and the side wall of the cone forms an angle of 45° with the horizontal plane to reduce the impact force during connection.

[0036] Furthermore, the conical cylinder is an electromagnet and an opening is provided at the top of the conical cylinder, and the button 33 is located inside the conical cylinder.

[0037] According to the technical solution of this embodiment, the rotating connection component 4 includes a rotating drum 41 rotatably connected to the bottom of the ship-based UAV 1 through a bearing. The interior of the rotating drum 41 is hollow, and a driven wheel 42 is coaxially installed on the top outer surface of the rotating drum 41. The outer surface of the driven wheel 42 is meshingly connected with a driving wheel 43. A pneumatic motor 44 is installed on the top of the driving wheel 43, and the starting motor is fixed to the bottom of the ship-based UAV 1. When the UAV needs to land, the pneumatic motor 44 is started to drive the driving wheel 43 to rotate, and the driven wheel 42 is driven to rotate through the rotation of the driving wheel 43, thereby driving the rotating drum 41 and the conical iron ring 45 to rotate accordingly. The rotation of the rotating drum 41 can be used to drive the surrounding airflow to rotate, resist external interference airflow, and facilitate reducing the interference of wind and waves on the landing of the UAV. In addition, compared with other motors, the pneumatic motor 44 has the advantages of lightweight and high safety factor, which can reduce the load of the ship-based UAV 1 and improve safety.

[0038] Furthermore, the bottom of the rotating drum 41 is configured to be conical, and the outer surface of the conical surface of the rotating drum 41 is sleeved with a conical iron ring 45, the angle between the conical iron ring 45 and the horizontal plane is 45°, and the conical iron ring 45 is adapted to the conical cylinder on the top of the electromagnetic suction cup 31, and can achieve a tight fit, thereby enhancing the landing stability.

[0039] According to the technical solution of this embodiment, the pneumatic fisheye lens monitoring assembly 5 includes a piston cylinder 51 fixedly connected to the bottom of the ship-based UAV 1, a support column 52 is installed at the output end of the piston cylinder 51, and a fisheye wide-angle lens 53 is installed at the bottom end of the support column 52. The piston cylinder 51, the support column 52 and the fisheye wide-angle lens 53 are all coaxially arranged with the rotating drum 41, and the fisheye wide-angle lens 53 is electrically connected to the ship-based UAV 1. The fisheye wide-angle lens 53 is used to capture the image during docking and transmit it to the ship-based UAV 1 in real time, so that the ship-based UAV 1 can obtain clearer and more accurate environmental information during the landing process, and the electromagnetic suction cup 31 and the conical iron ring are continuously approached by continuously adjusting the flight attitude, so as to perform precise alignment;

[0040] When the fisheye wide-angle lens 53 touches the button 33 on the inner upper end surface of the electromagnetic suction cup 31, it is considered that the conditions for docking and fixing are met. At this time, the piston cylinder 51 is started to drive the support column 52 and the fisheye wide-angle lens 53 to move downward, so that it presses the button 33 to turn on the circuit. At this time, the electromagnet of the electromagnetic suction cup 31 starts to work and attracts the conical iron ring. In this process, the fisheye wide-angle lens 53 always keeps pressing the button 33, so that the conical iron ring 45 and the electromagnetic suction cup 31 remain relatively fixed, thereby achieving stable landing.

[0045] S3. When the electromagnetic chuck 31 and the conical iron ring are adjusted to the appropriate position, the piston cylinder 51 is started to drive the support column 52 and the fisheye wide-angle lens 53 to move downward, so that the button 33 is pressed, and the electromagnetic chuck 31 is energized to attract the conical iron ring to achieve a stable landing;

[0046] S4. When the ship-based UAV 1 needs to take off, the piston cylinder 51 is started to drive the support column 52 and the fisheye wide-angle lens 53 to move upward, and the squeezing of the button 33 is stopped. At this time, the electromagnetic suction cup 31 is powered off and stops attracting the conical magnetic ring, and the ship-based UAV 1 can be separated from the hull.
