摘要

使用紫外光引导无人机飞行,具有抗干扰能力强、全天候非直视通信、保密通信能力强和适用于特殊场合等优点。因此,提供一种无人机匹配地形飞行的无线紫外光引导方法,以辅助无人机匹配不同地形飞行。提出一种基于紫外光的光功率控制方法,调整紫外信标发送端的角度和发射功率,使得到达无人机飞行平面的紫外光的功率相等,从而保障无人机安全飞行。对功率控制方法进行了计算机仿真。实验结果表明,紫外光LED发送张角不超过80°时,功率容易控制,信标集成易于实现,且受地形、高度等因素影响较小。

Abstract

Ultraviolet light guided flight offers many advantages for unmanned aerial vehicles (UAVs), such as strong anti-interference ability, all-weather operation, non-line-of-sight communication, strong secure communication ability, and suitability to special situations. This study presents a wireless ultraviolet guided method that assists UAV matching of different terrain flights, and proposes a control method of optical power based on ultraviolet light. By adjusting the angle and power of the transmitter of the ultraviolet beacon, the power of the ultraviolet light reaching the flight plane of the UAV is equalized, thereby ensuring the safety of the UAV flight. The power control method is simulated on a computer. When the transmission angle of the ultraviolet LED is 80° or less, the power is easily controlled; moreover, the beacon integration is easily achieved and is less affected by the terrain and height, among other factors.
