Portable light communication terminal

Abstract

The invention discloses a portable light communication terminal applied to electronic equipment. The portable light communication terminal comprises a light signal conversion module used for receiving external light communication signals and converting the signals into first electric signals, a signal processing module used for converting the first electric signals into communication signals capable of being received by electronic equipment, receiving the communication signals emitted by the electronic equipment and converting the communication signals into second electric signals, a light signal sending module used for receiving the second electric signals and converting the second electric signals outwards, and a storing module used for storing programs used for carrying out modulation and demodulation on interaction information between the signal processing module and the electronic equipment, wherein the storing module is arranged on a server and is for call of the electronic equipment. According to the light communication terminal, signal modulation and demodulation can be realized out of the light communication terminal, the light communication terminal structure is simplified, and portability requirement is satisfied.

Description

technical field [0001] The invention relates to a communication device, in particular to a portable optical communication terminal. Background technique [0002] According to reports, optical information communication researchers have prepared a visible light communication device that uses visible light to transmit network signals in the laboratory. The visible light communication device includes a visible light sending device and a visible light receiving device. Researchers connect the visible light communication device to a computer, and connect the network signal to the light-emitting diode in the visible light sending device, and use the visible light sending device to transmit the network signal Carry out code modulation and send out in the form of visible light. The visible light receiving device decodes and demodulates the network signal in the form of visible light. Through the data line input to the computer connected to it, network signal access is realized, and t...
