Laser energy supply communication system for air vehicle

Abstract

The invention discloses a laser energy supply communication system for an air vehicle. The laser energy supply communication system for the air vehicle comprises a ground energy supply station and the air vehicle. The ground energy supply station is mainly composed of a power supply, a laser driving unit, a laser unit, a beam shaping unit, an optical antenna, a two-dimensional rotary table, an electronic compass, a GPS sensing probe, a CCD image processing unit, a tracking capture control unit and a demodulation unit. The air vehicle is mainly composed of a photoelectric energy converting unit, an energy management unit, a battery pack, a detection unit and a reflection modulator. By means of the laser energy supply communication system for the air vehicle, energy is transmitted to the air vehicle through wireless laser, the working time of the air vehicle is effectively prolonged, meanwhile, the information of the air vehicle is modulated to a small part of laser returned along the original path based on the optical reflection principle, and laser communication between the air vehicle and the ground is achieved.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an aircraft laser energy supply communication system. Background technique [0002] As a practical aerial photography platform, drones and other aircraft will carry a certain amount of equipment (such as relay stations and / or various types of cameras, etc.) to complete aerial signal relay and shooting tasks. . Since traditional drones and other aircraft and the equipment they carry are powered by onboard batteries, if the battery is exhausted, the follow-up work cannot be completed. You can only let the aircraft land, replace the battery or charge the battery, and start again Follow-up. Such a power supply method greatly restricts the working hours of drones and other aircraft, unable to achieve a long-term aerial mission process, and significantly reduces work efficiency, which seriously hinders the development of drones and other aircraft. As drones and other air...

AI Technical Summary

Problems solved by technology

Because traditional drones and other aircraft and the equipment they carry are powered by on-board batteries, if the battery is exhausted, the follow-up work cannot be completed, and the aircraft can only be landed, replaced or charged for the battery, and then start again Follow-up

Such a power supply method greatly limits the working time of drones and other aircraft, making it impossible to realize a long-term aerial mission process, and the work efficiency is significantly reduced, which seriously hinders the development of drones and other aircraft.
