Abstract

The invention relates to a visible light both-way communication system. The system comprises an LED light source device with a visible light both-way communication function, and a visible light communication Internet device, wherein the visible light communication Internet device is capable of connecting with a mobile terminal, and the LED light source device comprises a power source module, a power line carrier module, a first Ethernet speed conversion module, an uploaded signal receiving modulating module, a downloaded emitting modulating module, and an LED light source module; the visible light communication Internet device comprises an uploaded signal emitting modulating, a downloaded signal receiving modulating module, a second Ethernet rate conversion module and an interface circuit. A light signal emitted by the LED light source module is the visible light incapable of generating radiated interference and harming the human body, and the transmission range of the light signal is the irradiation range of the LED light source device, the place out of the irradiation range is free from the light signal, and the irradiation range of the LED light source device is shielded, the privacy and the security of the communication are guaranteed.

Description

technical field [0001] The invention belongs to the field of visible light communication, in particular to a visible light two-way communication system, in particular to a two-way communication system composed of an LED light source device with a visible light communication function and a mobile terminal. Background technique [0002] With the rapid popularization of smart devices, the rapid increase in the number of users, and people's demand for high-speed broadband multimedia communications, the spectrum resources of wireless access networks are tight, coupled with the limitations of factors such as electromagnetic radiation interference, and the limitations of radio-on-fiber (RoF) technology. The immaturity has caused the traditional access network technology to perform profound and revolutionary changes, thus creating a resource to broaden the spectrum. The communication method of transmitting base stations through green and energy-saving LED lights is called visible lig...
