摘要
我们讨论了一种基于照明灯具的模块化可见光通信系统。利用发光二极管(LED)本身的频闪特性,将信号经过LED器件调制,发出人眼无法察觉到的高速调制光载波信号在空间中自由传输,通过光电探测器接收、再生、解调来实现信息的传递。通信单元采用模块化结构内嵌于吸顶灯、筒灯、射灯等各类灯具,使普通LED照明灯具具备了可见光通信功能,同时可以兼顾室内照明的专业要求。
The paper discusses a modular visible light communication system based on lighting fixtures.Using the strobe characteristics of light-emitting diode( LED),the signal can be modulated by LED devices,and the high-speed modulated optical carrier signal can transmit in the space freely,at last,through the photoelectric detector receiving,reproducing,and demodulating to achieve the delivery of information. The communication unit adopts the modular structure embedded in the ceiling lamp,down lamp,spotlight and other kinds of lamps,making the ordinary LED lighting fixtures have the visible light communication function,at the same time taking into account the professional requirements of indoor lighting.
