The invention relates to the technical field of visible light communication, and particularly discloses an emergency lighting and communication integrated system based on an unmanned aerial vehicle, and the system comprises the unmanned aerial vehicle equipped with an angle diversity transmitter, and a plurality of users located in a circular target area. The circular target area is fixed; the unmanned aerial vehicle hovers right above the circle center of the circular target area; the angle diversity transmitter comprises a central LED and N side LEDs which are obliquely and uniformly distributed around the central LED and are greater than or equal to 3; the central LED and the N side LEDs irradiate a circular target area at the same time; the hovering height of the unmanned aerial vehicle and the inclination angles of the N side LEDs need to be set so that an irradiation area jointly formed by the N side LEDs can fully cover a target area. The angle diversity transmitter is arranged on the unmanned aerial vehicle to adjust the inclination angle of the side LED, the cruising ability of the unmanned aerial vehicle is improved by selecting the optimal combination of the hovering height of the unmanned aerial vehicle and the inclination angle of the ADT, and the energy efficiency of the UAV-VLC system can be maximized.
本发明涉及可见光通信技术领域,具体公开了一种基于无人机的应急照明与通信一体化系统,系统包括一架配备有角度分集发射机的无人机,以及位于圆形目标区域的多个用户;圆形目标区域固定不变;无人机悬停于圆形目标区域圆心的正上方;角度分集发射机包括一个中心LED和围绕中心LED倾斜均匀分布的N≥3个侧面LED;中心LED和N个侧面LED同时向圆形目标区域照射;无人机的悬停高度和N个侧面LED的倾斜角的设置需使得N个侧面LED共同形成的照射区域全覆盖目标区域。本发明通过在无人机上配备角度分集发射机以对侧面LED的倾斜角进行调节,通过选取无人机悬停高度和ADT倾斜角的最优组合来提高无人机的续航能力,可以最大化UAV‑VLC系统的能效。
