Abstract

A visible light communication system is provided. The communication system includes at least one of a FFD and a visible light communication light source, and a RFD, wherein the visible light communication light source is configured to carry data information in a visible light signal and send the visible light signal; the RFD is in communication with the FFD and / or in communication with the visible light communication light source, and is configured to receive the visible light signal and demodulate the received visible light signal to recover data information; and the FFD is configured to achieve at least one of the following functions: the function of the visible light communication light source, the function of the RFD, and a function for forwarding the received visible light signal. In the present invention, the technical problem that visible light resources cannot be used fully because there is no network structure used for the visible light communications in the conventional art is solved, thereby achieving the technical effect of improving the utilization rate of the visible light.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a visible light communication system. Background technique [0002] In recent years, wireless communication technology using visible light has gradually attracted widespread attention from academia and industry, especially with the widespread use of lighting equipment such as light-emitting diodes (Light Emitting Diode, referred to as LED) While realizing lighting, the feasibility study of realizing wireless communication network coverage is being carried out in many related enterprises. It can be seen that the communication mode combining optical communication with wireless sensor network, wireless local area network (Wireless Local Area Network, referred to as WLAN), and power line communication system is also being discussed. However, it is certain that visible light communication technology will be one of the optional short-distance ultra-wideband communication methods in ...
