The invention discloses a visible light communication device which belongs to the field of communication devices. The visible light communication device is composed of a signal sending module and a signal receiving module. The signal transmitting module mainly receives the common optical signal, and then modulates the received signal to be transmitted into the optical signal, and sends out information in the form of an optical signal. At the same time, some modules are powered by the existing optical signals. The signal receiving module mainly receives the modulated optical signal, converts itinto the electric signal, processes and demodulates to obtain the signal to be sent, completes the transmission of the signal, and utilizes the received modulated optical signal to supply power, thussolving the problem of energy waste caused by not using the existing light source to supply power in the visible light communication. The visible light communication device can be used in the fieldsof communication, transportation, industry and intelligent life.
Description
technical field [0001] The invention belongs to the field of communication devices, in particular to a visible light communication device. Background technique [0002] Visible Light Communication technology (Visible Light Communication, VLC) refers to the use of light in the visible light band as an information carrier, without the need for transmission media such as optical fibers, and directly transmits optical signals in the air. At the same time, it is suitable for use in the field of information security. As long as the visible light is blocked, the information in the VLC communication network will not be leaked, and it has a high degree of confidentiality. [0003] Visible light communication technology is green and low-carbon, can realize almost zero energy consumption communication, and can effectively avoid weaknesses such as radio communication electromagnetic signal leakage, and quickly build an anti-interference and anti-interception security information space. ...
