摘要
LED可见光作为一种绿色环保、低功率、高亮度的照明光,在当今人们的日常生活和工作中得到了广泛的应用。根据光通信的基本原理,设计出以STC89C52RC单片机为核心的LED可见光通信系统。系统采用单片机作为LED光信号的发射和接收模块,通过对LED光信号的直接调制和检测,并利用串口调试软件辅助实现终端设备间的LED光通信,最终实现了PC间的简单单工数据通信。
LED visible light as a green, low power, high brightness of the lighting, in today＇s people＇s daily life and work has been widely used. According to the basic principle of optical communication, the LED visible light communication system based on STC89C52RC SCM is designed.. System uses a microcontroller as the LED light signal of the transmitting and receiving module by on the LED light signal of direct modulation and detection, and the use of serial debugging software to achieve the terminal equipment between the LED light communication, finally realizes the PC simple simplex data communication.
