Abstract

The present disclosure relates to the technical field of visible light communication, and in particular to a data transmission method based on visible light communication, a data transmission device based on visible light communication, a data transmission system based on visible light communication, and a computer-readable medium. The method includes: obtaining current environmental parameters, matching the target light source array according to the environmental parameters; modulating the data to be transmitted according to preset rules to obtain corresponding target electrical signals; making the target light source array send the target electrical signals. In the present disclosure, the corresponding target light source array can be selected for data transmission according to the change of the actual environment, and the efficiency of data transmission can be effectively improved.

Description

Technical field [0001] The present disclosure relates to the field of visible optical communication, and more particularly to a data transmission method based on visible light communication, a data transmission device based on visible light communication, a data transmission system based on visible communication, and a computer readable medium. Background technique [0002] Visible Light Communication, VLC) technology is to transmit information using a high-speed mating dark blinking signal emitted by a fluorescent or light-emitting diode or the like, and connect the wire device of the high-speed Internet to the lighting device, insert the power plug. be usable. The system made by this technology can cover the range of indoor lights, and the computer does not require wire connections, therefore has extensive development prospects, compared to traditional RF communications and other light wireless communication, there is no electromagnetic radiation, and light You can communicate,...
