Single unmanned aerial vehicle charging parking apron guiding landing system based on infrared or visible light beams

Abstract

The invention relates to a single unmanned aerial vehicle charging parking apron guiding landing system based on infrared or visible light beams. The single unmanned aerial vehicle charging parking apron guiding landing system involves an unmanned aerial vehicle end, a parking apron end, and a server end, wherein an unmanned aerial vehicle is provided with a microprocessor and a beam transceiver,the beam transceiver is arranged at the bottom of the unmanned aerial vehicle, can vertically downwards emit the light beams under the control of the microprocessor, and can receive an optical signalfrom the parking apron end and transmit the optical signal to the microprocessor; the parking apron end comprises a microprocessor and a beam transceiver, wherein the beam transceiver is arranged on aparking apron, can vertically upwards emit the light beams under the control of the microprocessor, and can receive an optical signal from the unmanned aerial vehicle end and transmit the optical signal to the microprocessor; and the server end carries out calculating according to a three-dimensional coordinate, a flight speed and direction reported by the unmanned aerial vehicle, and a three-dimensional coordinate of the parking apron to obtain a relative position distance, forms and sends out a guidance scheme instruction for controlling the unmanned aerial vehicle to move in the position connecting line direction, and sends out the instruction to the unmanned aerial vehicle through the parking apron end.

Description

technical field [0001] The invention relates to the technical field of optical communication, and specifically designs a set of guided landing system for single UAV charging apron based on infrared or visible light beams. Background technique [0002] Infrared beam ranging can measure a long distance without a reflector and low reflectivity. With the development and progress of LED light source technology, white LEDs with the advantages of high brightness, low power consumption, and long life have gradually replaced fluorescent lamps and incandescent lamps. Due to the convenient modulation and quick response of white light LED communication, it has obvious advantages compared with ultraviolet and radio frequency methods in terms of harmless radiation, security, and stability. It has become an emerging visible light communication (VLC) method, which is gradually being extended to indoor positioning. field. The existing infrared and LED beam ranging methods can maintain the ...

AI Technical Summary

Problems solved by technology

However, the apron has requirements for the position and stability of the UAV docking, and it is difficult to effectively inductively charge the UAVs that are docked and shifted.

In the stage of UAV landing, most of them rely on the operator's subjective experience to perform remote control, and the accuracy of the existing automatic control landing is also difficult to accurately locate the small area of ​​​​the apron.
