Abstract

The invention discloses a method, a device and a system for realizing information transmission based on visible light. The method for realizing information transmission based on visible light comprise the following steps: encoding a file to generate bit information when sending file information; grouping the bit information to get bit groups, wherein only the bit information in the same bit group is displayed on a screen at the same time; displaying the bit information in the bit groups screen by screen, wherein the bit information is modulated into pixels of corresponding colors for display, so that a receiving device can acquire images displayed on the screen, and the file is sent to the receiving device. By transmitting data in real time using a screen or an image acquisition unit such as a camera, the transmission process is simplified, the speed and reliability of directional data transmission are improved, and the problem that the existing system is susceptible to interference and is low in transmission rate is solved. A new technological path is provided for visible light communication.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for realizing information transmission based on visible light. Background technique [0002] The traditional end-to-end file transfer methods mainly include Bluetooth, data cable, infrared ray, WiFi, etc. These methods solve the problem of user file transfer and improve the transmission speed, but at the same time, they also have complex operation methods, poor confidentiality, There is a bottleneck in the transmission speed and there is little room for speed improvement. [0003] Visible Light Communication (VLC for short) is a new type of wireless communication technology based on visible light. Visible light communication can provide a short-distance, safe, and interference-free wireless link. Compared with traditional radio frequency communication, it has obvious advantages. However, the current visible light communication technology is suscepti...
