Vertical take-off and landing unmanned aerial vehicle mobile platform landing guide device and guide method thereof

Abstract

The invention discloses a vertical take-off and landing unmanned aerial vehicle mobile platform landing guide device and a guide method thereof, and belongs to the field of shipboard unmanned aerial vehicle landing navigation. The device comprises a stable platform carried on a ship deck. The stable platform comprises a target, an upper platform, a lower platform, an electric cylinder and three supporting rods, and the electric cylinder controls the three supporting rods to perform three-degree-of-freedom motion, so that attitude motion in the pitching direction, the rolling direction and theyawing direction of the deck is compensated; when the vertical take-off and landing unmanned aerial vehicle is about to land on the deck, the unmanned aerial vehicle firstly autonomously follows the deck to move and gradually approaches a landing point until reaching the position above the target; the height of the unmanned aerial vehicle is gradually reduced to be close to a landing point througha dynamic-to-dynamic differential relative positioning technology until the deck reaches a visual capture point of the unmanned aerial vehicle, and visual navigation is introduced into the unmanned aerial vehicle; meanwhile, the deck automatically adjusts the inclination angle to counteract deck posture movement, and stable landing of the unmanned aerial vehicle is guaranteed. The structure is simple, full-autonomous deck landing of the unmanned aerial vehicle is achieved, and the landing guiding precision is improved.

Description

technical field [0001] The invention belongs to the field of shipboard unmanned aerial vehicle landing navigation, in particular to a vertical take-off and landing unmanned aerial vehicle mobile platform landing guide device and a guide method thereof. Background technique [0002] The drone industry has developed rapidly in recent years, and its integration with various fields has become more extensive. Compared with traditional manned carrier-based aircraft, carrier-based UAVs are smaller in size and more autonomous when performing tasks such as maritime exploration, aerial reconnaissance, or long-range strikes. They also have flexible combat capabilities, good stealth performance, and can ignore the human body. Extreme all-weather work in harsh environments such as high-altitude hypoxia, while having the advantage of zero casualties, it plays a vital role in the modern navy. [0003] China is a large maritime country with a large territorial sea and a long coastline. The...

Problems solved by technology

Since both the base station and the UAV are in motion, relying only on the traditional GPS single-point positioning accuracy is insufficient, differential GPS positioning will bring large errors due to the movement of the base station, inertial navigation has cumulative errors, and radar navigation is easy to be detected. detection interference
