Abstract
The utility model discloses a two-dimensional code information identification system. The system comprises a light source, an optical system, a central processor, a memory, a loudspeaker and a display, wherein the light source, the optical system and the central processor are connected in turn, and the memory, the loudspeaker and the display are connected with the central processor. The optical system is composed of a lens and a photoelectric conversion chip. The photoelectric conversion chip is located at the rear part of the lens. According to the utility model, an invisible two-dimensional code hidden below ink can be identified; fast decoding can be carried out on the collected invisible two-dimensional code; the display carries out display in real time or the loudspeaker issues regulated sounds in real time; and the two-dimensional code information identification system has the advantages of simple hardware circuit structure and high practicality and reliability.
Description
Technical field
The utility model relates to 2 D code information recognition technology field, particularly a kind of 2 D code information recognition system.
Background technology
Two-dimension code (dimensional barcode) claims again two-dimensional bar code, is a kind of bar code with readability that expands on the basis of bar code.The device scan two-dimensional bar code, the binary data by putting down in writing in the identification length of bar code and the width can obtain the information that wherein comprises.Compare bar code, the data that the two-dimension code record is more complicated are such as picture, network linking etc.Along with a large amount of of a series of digital products such as mobile phone that carry camera popularize, two-dimension code also was widely used in the last few years.
The two-dimension code of ordinary printed is owing to can not preventing from copying, so have certain shortcoming aspect false proof.Along with the development of the progress of society and science and technology, the invisible two-dimensional codes that uses invisible printing ink to print has appearred, and invisible two-dimensional codes is because high security and the reason such as attractive in appearance are subject to the attention of industry day by day.Existing invisible two-dimension code recognition device all adopted with invisible two-dimensional codes be buckled in recognition device below, in building the dark surrounds of sealing, it identifies, but because Concealed label can't be seen by naked eyes when radiation of visible light, so the user just is difficult to be aligned in accurately recognition device on the invisible two-dimensional codes, cause recognition resolution not high, the problem of identifying difficulty.
The utility model content
For this reason, the utility model proposes a kind of 2 D code information recognition system, can eliminate fully because the restriction of prior art and one or more problems that defective causes.
The utility model additional advantage, purpose and characteristic, a part will be elucidated in the following description, and another part will be significantly for those of ordinary skill in the art by the investigation to following explanation or acquire from enforcement of the present utility model.Can realize and obtain the utility model purpose and advantage by the structure of in the instructions of literal and claims and accompanying drawing, pointing out especially.
The utility model provides a kind of 2 D code information recognition system, described system comprises light source, optical system and the central processing unit that connects successively, and the storer, loudspeaker and the display that are connected with described central processing unit, wherein, described optical system is comprised of lens and opto-electronic conversion chip, and described opto-electronic conversion chip is positioned at the rear portion of described lens.
Preferably, described light source is cold-cathode fluorescence lamp.
The utility model can be identified the invisible two-dimensional codes that is hidden under the printing ink, and the invisible two-dimensional codes that collects is decoded fast, by the real-time demonstration of display or by the real-time sound that sends regulation of loudspeaker.The utility model hardware circuit is simple, has very high practicality and reliability.
Description of drawings
Fig. 1 is according to structural representation the utility model embodiment, the 2 D code information recognition system.
Embodiment
With reference to the accompanying drawings the utility model is described more fully, exemplary embodiment of the present utility model wherein is described.
As shown in Figure 1,2 D code information recognition system disclosed in the utility model comprises light source 1, optical system 2 and the central processing unit 3 that connects successively, and the storer 4, loudspeaker 5 and the display 6 that are connected with described central processing unit 3.
Light source 1 in the utility model is the ultraviolet source that can launch ultraviolet light, preferably adopts cold-cathode fluorescence lamp as light source 1, and this light source 1 can send the short wave ultraviolet light of 254nm.Described optical system 2 is comprised of lens 21 and opto-electronic conversion chip 22, and described opto-electronic conversion chip 22 is positioned at the rear portion of lens 21, and it can receive the light through lens 21.Described opto-electronic conversion chip 22 can send to the 2 D code information that collects central processing unit 3.
3 pairs of two-dimension codes of central processing unit are decoded, and read the sound corresponding with this two-dimension code or view data from storer, to export at loudspeaker 5 or display 6.
When the short wave ultraviolet light of the 254nm that the light source 21 of 2 D code information recognition system of the present utility model sends shines on the Concealed label, reflected light is after lens 23 focus on, shine on the opto-electronic conversion chip 22, so opto-electronic conversion chip 22 receives reflected signal, directly light signal is converted to electric signal by this opto-electronic conversion chip 22, then be sent to central processing unit 3 and decode, and real-time loudspeaker 5 or the display 6 of being sent to broadcasted or shown.
2 D code information recognition system of the present utility model can emitting ultraviolet light, so that the invisible two-dimensional codes that is printed on the commodity produces the figure that naked eyes can be seen, and this invisible two-dimensional codes naked eyes under the irradiation of visible light are None-identifieds, thereby, the utlity model has very high practicality and reliability.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
Claims (2)
