Description
Technical field
The utility model relates to a kind of LED visible light communication audio transmission demonstrator.
Background technology
Visible light communication technology be utilize that LED luminous intensity is high, good stability, response characteristic at a high speed, by LED send discernable by eye not high speed light and shade flash signal out diffuse information, be the new communication technology of of enjoying international academic community to pay close attention in recent years.This technology is still not market application widely at present, therefore needs a kind of demonstration instrument to show that it is in teaching using value.
Summary of the invention
The purpose of this utility model is to provide a kind of LED visible light communication audio transmission demonstrator.
The utility model solves the technical scheme that its technical matters adopts: the utility model utilizes visible light communication technology with the form of simulating signal transmission MP3 audio frequency, to reach demonstration visible ray optical communication object.The utility model is by transmitter module, receiver module and external power supply module composition, wherein transmitter module comprises white LED lamp support, white LED lamp, white LED lamp driving circuit, signal amplification circuit, MP3 voice playing module, receiver module comprises silicon photocell support, silicon photocell, loudspeaker, multistage amplifier circuit, power amplifier, and external power supply module comprises 5V DC power source adapter, switch.
Specific works mode is: white LED lamp, silicon photocell are separately fixed on two vertical racks, makes two stands at a distance of 1m just to placement.Open switch, it is system power supply that 220V alternating current is converted to 5V direct current by 5V power supply adaptor, and MP3 voice data is converted to simulating signal in MP3 voice playing module.The simulating signal that MP3 voice playing module exports amplified by signal amplification circuit, the simulating signal after amplification realizes the fast modulation to white LED lamp through LED lamp drive circuit, and simulating signal is converted into light signal.MP3 voice data is delivered to just right silicon photocell in the form of light, utilizes the photoelectric effect of silicon photocell the light signal transmitted to be converted into the simulating signal with sound signal with identical change rule.Multistage amplifier circuit is made up of pre-amplification circuit and main amplifying circuit, after this simulating signal is amplified by multistage amplifier circuit, is reduced into the simulating signal identical with transmitting terminal.Carry out power amplification by power amplifier to simulating signal afterwards, finally this signal enters speaker drive loudspeaker and sounds, and completes white LED lamp to MP3 audio information transmissions, realizes the demonstration of visible light communication audio transmission.
The beneficial effects of the utility model are: simple to operation, and demonstrating effect is directly perceived, and transmission range is comparatively far away, and audio fidelity is high.Achieve the visible light communication carrying out audio transmission with simulating signal, the white LED lamp communication technology can be shown intuitively.
