Abstract

The invention provides a visible light duplex communication device, comprising a first transmit-receive module, a second transmit-receive module and an optical communication module; wherein both the first transmit-receive module and the second transmit-receive module are used for receiving and transmitting a multimedia signal; the optical communication module comprises a first quantum well diode device and a second quantum well diode device which are connected through an optical waveguide; the first quantum well diode device is connected with the first transmit-receive module, the second quantum well diode device is connected with the second transmit-receive module; and the optical communication module is used for achieving duplex communication of the multimedia signal between the first transmit-receive module and the second transmit-receive module in the way of optical transmission. The visible light duplex communication device of the invention has the beneficial effects that: a transmission mode of the multimedia signal is changed from conventional electronic transmission or radio wave transmission into photon transmission, thereby greatly improving a transmission efficiency of the multimedia signal; at the same time, duplex communication of the multimedia signal is achieved, and the function of the visible light duplex communication device is expanded.

Description

technical field [0001] The invention relates to the technical fields of visible light communication, intelligent lighting and display, in particular to a visible light duplex communication device. Background technique [0002] Visible Light Communication (Visible Light Communication, VLC) is a new, short-distance, high-speed wireless communication technology developed on technologies such as Light Emitting Diode (LED). It uses LED as the light source, the atmosphere or water as the teaching medium, and transmits information by sending out visible light signals that are imperceptible to the naked eye and flickering at a high speed. Signal reception, regeneration, demodulation to realize the transmission of information. Compared with traditional wireless radio frequency communication technology, VLC has the following advantages: low energy consumption, less equipment purchased, etc., in line with the national energy conservation and emission reduction strategy; no electromagn...
