Abstract
The invention discloses an NFC-based explication device. The NFC-based explication device comprises a magnetic head, a switch, a battery, an MCU, an audio processing module and a loudspeaker, wherein the magnetic head and the switch are arranged on the outer portion of a device body, and the battery, the MCU, the audio processing module and the loudspeaker are arranged in the device body; the switch is used for controlling the battery to be powered on or off; the battery is used for supplying power to the magnetic head, the MCU, the audio processing module and the loudspeaker; the magnetic head is used for scanning NFC labels pasted on articles and transmitting information obtained after scanning to the MCU; the MCU is used for analyzing the information transmitted by the magnetic head and transmitting the information relevant to the NFC labels to the audio processing module; the audio processing module converts the explication information into sound signals and transmits the sound signals to the loudspeaker. The NFC labels are utilized for marking the articles, complicated wiring in a museum or an exhibition hall can be avoided, the attractiveness of the exhibition hall is improved, and electricity can be saved.
Description
Technical field
The present invention relates to a kind of commenting unit based on NFC.
Background technology
Existing commenting unit is infrared ray article commenting unit, and its shortcoming is that infrared emitter needs power supply, accepts infrared terminal
Also to power, have too many article inside museum, need the circuit built the most and loaded down with trivial details, infrared ray is too many
Can produce interference, visual effect is the most unsightly.Also can often occur infrared-ray to disturb, affect visitor and visit.
Also having a kind of commenting unit is by location, just plays specific content when visitor goes to specific place, and its content is
Substantially overview, does not has the detailed explanation of each product, and visitor oneself can't select specific article explanation, detailed solution
Saying word to be seen, word occupies a lot of space and does not has the vivid of speech sound eeplaining.
Summary of the invention
The present invention seeks to provide one for the defect that prior art exists to need not build complicated circuit, can do for passenger
The hand-held commenting unit explained orally in detail.
The present invention for achieving the above object, adopts the following technical scheme that a kind of commenting unit based on NFC, including being arranged on solution
Say the magnetic head outside device and switch, and be arranged on the battery within commenting unit, MCU, audio processing modules and loudspeaker；
Described switch is used for controlling Cell On-Off electricity；
Described battery is used for as magnetic head, MCU, audio processing modules and power speakers；
The NFC label that described magnetic head is attached on article for scanning, and the information scanned is passed to MCU；
Described MCU is for analyzing the information of magnetic head transmission, and the information relevant to NFC label is passed to audio processing modules；
Explainative information is converted into voice signal and passes to loudspeaker by described audio processing modules.
Preferably, being additionally provided with display screen outside described commenting unit, described display screen is for receiving from MCU about explainative information
The time data needed, and data are shown.
Preferably, being additionally provided with volume knob outside described commenting unit, described volume knob is used for controlling speaker
Amount.
Beneficial effects of the present invention: utilize NFC label to be identified, NFC label need not power supply, and handheld terminal is provided for oneself and filled
Electricity battery, museum need not add power circuit, does not also have infrared-ray interference, it is ensured that visitor visits smoothly；
And in handheld terminal, having detailed article explanation, passenger can select oneself interested according to the hobby of oneself completely
Article are understood, and detailed sound explains orally the most vivid.
Accompanying drawing explanation
Fig. 1 fundamental diagram of the present invention；
Fig. 2 present configuration schematic diagram.
Detailed description of the invention
Fig. 1 show a kind of commenting unit based on NFC, including the magnetic head 4 being arranged on outside commenting unit 9 and switch 2, with
And it is arranged on the battery 3 within commenting unit 9, MCU5, audio processing modules 6 and loudspeaker 7；Described switch 2 is used for controlling
Battery 3 power on/off processed；Described battery 3 is for powering for magnetic head 4, MCU5, audio processing modules 6 and loudspeaker 7；Institute
State magnetic head 4 for the NFC label that is attached on article 10 of scanning, and the information scanned is passed to MCU5；Described MCU5
For analyzing the information of magnetic head 4 transmission, and the information relevant to NFC label is passed to audio processing modules 6；Described sound
Frequently explainative information is converted into voice signal and passes to loudspeaker 7 by processing module 6.Wherein, described commenting unit 9 is outside also sets
Display screen 1, described display screen 1 is had to be used for receiving the time data needed from MCU5 about explainative information, and by data
Showing, the outside volume knob 8 that is additionally provided with of described commenting unit 9, described volume knob 8 is raised one's voice for control
Device 7 volume.
Commenting unit 9 shell is provided with switch 2, magnetic head 4, volume knob 8 and display screen 1, at commenting unit 9
Inside is provided with battery 3, MCU5, audio processing modules 6, loudspeaker 7.
Stick NFC label in article 10 appropriate location in museum or exhibition center, when needing to listen explanation, open switch, solve
Saying that the battery 3 in device 9 is just energized for each equipment, hand-held commenting unit magnetic head 4 on hand can be directed at NFC mark by visitor
Signing, magnetic head 4 scans label, label is passed to MCU5 and is identified, and transfers the information relevant with this label, by this
A little information pass to audio processing modules 6, and audio processing modules 6 converts digital signals into voice signal and passes to loudspeaker
7, loudspeaker 7 by voice signal broadcast, MCU5 also can by play with label relevant information required for Time Transmission give display
Screen 1, time showing is out supplied visitor to check by display screen 1, and volume knob 8 can control the volume of loudspeaker 7.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the spirit and principles in the present invention
Within, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
