Problems solved by technology

In addition, when UAVs land on mobile platforms such as warships and vehicles, due to the constant changes in the attitude, position and speed of the platform, the UAV needs to quickly and accurately adjust its own attitude to maintain contact with the mobile platform. Synchronous movement, the landing process is very difficult and dangerous
Therefore, the previous UAV take-off and landing methods are highly dangerous and have few applicable occasions, and it is difficult to meet the current UAV application requirements.

Abstract

The ground station full power takeover control system during the take-off and landing phase of the UAV belongs to the field of UAV technology, and is characterized in that it includes: UAV control department and ground station control department; among them, the UAV control department includes: airborne sensor Group, flight control computer, steering gear adapter, steering unit, downlink data link transmitter and uplink data link receiver; ground station control department, including: ground station, downlink data link receiver, uplink data link transmitter , take-off and landing platform and take-off and landing platform sensor group; during the take-off and landing stages of the UAV, the flight control computer uses the downlink data link to send the flight data to the ground station; the ground station uses the relative motion of the UAV and the take-off and landing platform relationship, continuously calculate the UAV control instructions, and manipulate the UAV through the uplink data link, so that it can complete take-off and landing under the full control of the ground station. The invention can improve the safety of the unmanned aerial vehicle in the take-off and landing stages, and expand its application occasions.

Description

technical field [0001] The invention is a device for controlling the automatic take-off and landing of the unmanned aerial vehicle, which can fully automatically guide and control the take-off and landing of the unmanned aerial vehicle in complex environments. It is mainly used in technical fields such as aerospace, drones and robots. Background technique [0002] The take-off and landing of UAVs is a high-incidence phase of crashes, and the accident rate is even higher when UAVs take off and land in complex environments (such as narrow areas or moving platforms). The automatic take-off and landing of UAVs can usually only be completed under good landing conditions such as wide and flat fields, while remote control is the main method in complex environments. In addition, when UAVs land on mobile platforms such as warships and vehicles, due to the constant changes in the attitude, position and speed of the platform, the UAV needs to quickly and accurately adjust its own atti...
