基于可见光通信的新型LED节日彩灯控制器设计

摘要

A multi-mode display control system based on single chip STC12C5A60S2 was designed,in which the single chip STC12C5A60S2 is taken as its control core,and the peripheral circuits such as the wireless remote control circuit,audio input circuit and LED display circuit are used.The system has two control modes:the wireless remote control and manual control,and also has three application modes:general lighting,cool moving painting and music spectrum.These characteristics make the system adapt to application requirements of different occasions.In addition,the LED is adopted as display screen of the system.The LED can act as the role of communication tools instead of the WLAN,WiFi or Bluetooth in some places that are not suitable for electromagnetic transmission.The system can realize three functions:lighting,decoration and visible light communication.%以STC12C5A60S2单片机为核心,结合无线遥控、音频输入、LED显示等外围电路,设计实现了一种基于单片机的无线遥控/手动双重控制的多模显示控制系统.系统具有普通照明、酷炫动画及音乐频谱三种应用模式,适应不同场合应用需求.采用LED作为显示屏,可代替WLAN,WiFi或蓝牙等,在一些不适合电磁传输的场所充当通信工具的角色,实现照明、装饰及可见光通信的三重功能.
