UWB guidance system of automatic landing of unmanned aerial vehicle

Abstract

The invention discloses a UWB guidance system for automatic landing of UAVs; this system is based on UWB technology, UWB capture device captures UWB signals of ground UWB marking points, sends UWB signal data to DSP for processing, and calculates UWB and UWB marking points The flight control system controls the action of the UAV according to the horizontal error; the UWB signal of the UWB marking point on the ground is sent to the field controller by the operator through the operation center and the communication device, and the field controller controls the UWB transmitter to transmit to the UWB marking point UWB signal. Solve the problem that the existing UAV-assisted landing system based on image recognition cannot be used at night, and if the apron is supplemented with light, it is easy to expose the target, and it is not easy to be used in places that need to be concealed.

Description

technical field [0001] The invention relates to an auxiliary system for landing an unmanned aerial vehicle, in particular to a UWB guidance system for automatic landing of an unmanned aerial vehicle. Background technique [0002] As an important part of the key technology of autonomous control, the autonomous take-off and landing of drones is the premise of realizing the recovery and reuse of drones. According to the requirements of combat performance, UAVs have the characteristics of simultaneous take-off and landing of multiple sorties, and the airport is close to the battle front. Therefore, UAVs are required to take off on small airports without fixed runways or short-distance runways. Vertical take-off and landing mode. Take-off is simpler than landing, mainly including two stages of acceleration run and lift-off climb. When the take-off conditions are met, take-off can be realized through relatively simple program control, and there is not much requirement for the aut...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing UAV assisted landing system based on image recognition cannot be used at night, and if the parking apron is supplemented with light, it is easy to expose the target and is not easy to be used in places that need to be concealed. The UWB guidance system for man-machine automatic landing solves the problem that the existing UAV-assisted landing system based on image recognition cannot be used at night, and if the apron is supplemented with light, it is easy to expose the target and is not easy to use in places that need to be concealed.
