Laser communication and tracking system for unmanned aerial vehicle

Abstract

The present invention relates to a laser communication and a tracking system for an unmanned aerial vehicle, after tracking and positioning the unmanned aerial vehicle, a photoelectric tracking subsystem sends beacon light and signal light sent by a communication subsystem to the unmanned aerial vehicle through a relay optical subsystem, in the same time receives an unmanned aerial vehicle signal,and realizes wireless laser communication between the unmanned aerial vehicle and a main control computer to transmit position and flight attitude of the unmanned aerial vehicle to a main control computer terminal with a liquid crystal display in real time. When transmitting energy to a moving target, the system has high tracking accuracy and stable energy transmission efficiency, realizes the laser communication and tracking aiming of the unmanned aerial vehicle, and can fully combine structural characteristics of the unmanned aerial vehicle for remote laser charging. The high-precision real-time tracking system provides uninterrupted power to the unmanned aerial vehicle, does not require manual control and adjustment of incident laser angles, ensures that a solar battery always outputsmaximum power, thereby greatly reducing energy storage equipment on the vehicle, and has stable energy transfer.

Description

technical field [0001] The invention relates to a communication tracking technology, in particular to a laser communication and tracking system for unmanned aerial vehicles. Background technique [0002] In recent years, the technology of aerial vehicles, especially small aircrafts, has developed rapidly. At present, small aircrafts have limited battery life and need to land and recharge regularly, which will affect their work efficiency. new options. As far as the current laser charging technology is concerned, there are still technical problems that need to be solved urgently, such as the large depletion coefficient of the laser angle, it is difficult to ensure the normal incident condition of the laser, which makes the energy transmission efficiency low and causes a large amount of energy loss. [0003] With the continuous development of science and technology, laser wireless energy transmission technology has been widely used in people's daily life, work and industry, w...

Problems solved by technology

Especially when the target system, that is, the system that receives laser energy is a moving target such as a UAV or a space spacecraft, a low-precision tracking and targeting system will cause part of the laser beam to "miss", so that some photocell panels do not receive laser radiation. Lighting, resulting in energy loss, directly leads to the reduction of energy transmission efficiency
