A Design of Image Transmission System Based on Visible Light Communication

摘要:

针对目前可见光通信传输速率低、难以实现图像通信的问题,通过研究高亮度白光LED光强调制原理和光电检测器特性,研制了一种可见光图像传输系统.设计了系统的光发射与接收电路,编写了图像传输与显示程序.通过实验验证,系统实现了通信速率为2Mbit/s的PC机到PC机的字符及图像传输,为高速可见光通信的发展提供了一种可靠的电路设计方案.

Abstract:

Now it is difficult to realize the image transmission based on the visible light communication because of low transmission rate.An image transmission system based on visible light communications is developed by studying the modulation principle of the high-brightness white LED and property of the photodetector.The light transmitter circuit and receiving circuit are designed in the system,as well as the software of image transmission and display are programmed.Eexperimental results verify that the system can comply characters and images communication in 2Mb/s from PC to PC,so it provides a reliable circuit proposal for the progress of high speed visible light communication.
