Abstract

The invention discloses a visible light communication method and system. The method comprises the following steps: an automobile terminal receives a visible light signal sent by a traffic light; the automobile terminal analyzes the visible light signal when receiving the visible light signal to obtain a data transmission protocol frame, wherein the data transmission protocol frame comprises a starting symbol, a device address, an instruction code, a data domain, a termination symbol and a check code; and the automobile terminal displays text information and / or adjusts the working parameters of a home terminal according to the data transmission protocol frame. By adoption of the visible light communication method and system disclosed by the invention, the information transmission and information interaction efficiency of visible light communication are improved.

Description

Technical field [0001] The present invention relates to the technical field of visible light communication, in particular to a visible light communication method and system. Background technique [0002] With the development of LED technology, Visible Light Communication (VLC) has become one of the research hotspots of a new generation of wireless communication technology. While using LED lighting, VLC modulates the signal on the LED light source, and uses the visible light band as a communication carrier to transmit data. However, the efficiency of information transmission and information interaction in the existing visible light communication process is low. Summary of the invention [0003] The main purpose of the present invention is to provide a wireless direct connection method and device, which aims to improve the efficiency of information transmission and information interaction of visible light communication. [0004] In order to achieve the above objective, a visible lig...
