Abstract

An embodiment of the invention discloses a method and a system for transparently transmitting full-IP (internet protocol) visible light data. The method and the system aim to realize electromagnetic compatibility among communication equipment and other electronic devices. The system comprises visible light communication terminals and visible light communication illuminating devices (connected into a power line grid), and IP addresses are distributed to the visible light communication terminals and the visible light communication illuminating devices. Each visible light communication illuminating device consists of a power line router modem and a visible light receiving and transmitting device, and each visible light communication terminal consists of a visible light receiving and transmitting device. Conversion between visible light signals and the IP data meeting TCP / IP (transmission control protocol / internet protocol) requirements can be carried out by the visible light receiving and transmitting devices, so that visible light communication among the visible light communication terminals and the visible light communication illuminating devices is realized, and intercommunication between the power line grid and a VLC (visible light communication) network is realized by the power line router modems. In addition, the visible light frequency band ranges from 400THz to 800THz, the common radio frequency band is avoided, and accordingly the problem of electromagnetic interference among the system and other electronic devices is avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method and system for transparent transmission of all-IP visible light data. Background technique [0002] When traditional data communication methods are applied in mines, indoors and other scenarios, since the working frequency of wireless communication terminals at the physical layer is mostly concentrated in the common radio frequency band (several GHz to tens of GHz), wireless communication equipment There are electromagnetic compatibility issues with other electronic equipment. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide an all-IP visible light data transparent transmission method and system, so as to solve the problem of electromagnetic compatibility between a communication device and other electronic devices. [0004] In order to achieve the above purpose, embodiment...
