Research and Design of Visible Light Communication

通过分析可见光通讯技术的理论,提出了一种用于传输各种字符的"可见光通信"方案。该方案包括发送端和接收端,具体实现电路由主控模块、电源模块、晶振电路、信号发送、矩阵键盘、光电检测模块、LCD显示电路组成;STC12C5A60S2单片机作为发送端和接收端的主控制器,可以实现控制LED灯的亮灭来传递信息。该系统具有电路设计合理、原理清晰、集成度高和数据更新快等优点,在通信行业具有很好的实用价值。

Through analyzing the the theory of visible light communication technology, this paper proposes a scheme of＂visible light communication＂ for the transmission of various characters. The scheme includes sending end andreceiving end. The circuit is composed of main control module, power supply module, crystal oscillator circuit, signalsending, matrix keyboard, photoelectric detection module and LCD display circuit. STC12C5A60S2 single chipmicrocomputer is the main controller of sending end and receiving end. The microcomputer realizes the control of theLED light on and off, and the LED light is on and off to carry the information. The system has reasonable circuitdesign, clear principle, high integration and fast data update, it has good practical value.
