Abstract

A recognizing anti-fake voice pen belongs to the field of an anti-fake detection tool, and comprises an outer barrel of the recognizing anti-fake pen, an outside link single chip computer and an audio processing equipment, and is characterized in that a camera lens is arranged in the outer barrel of the recognizing anti-fake voice pen, and is connected with a sensor, and then is connected with an image interface chip electric circuit, threads through USB interface and is connected with the single chip computer, finally, the voice is output after the audio is processed. The recognizing anti-fake voice pen can read the invisible lattice code quickly and exactly, and has good safe anti-falsification and anti-replicability.

Description

The recognition anti-counterfeiting voice pen

Technical field

The utility model belongs to the anti-counterfeiting detection field of tool, specially refers to a kind of recognition anti-counterfeiting voice pen that is used for digital identification range.

Background technology

Because the coding rule of bar code and two-dimensional bar code is open, for example representative two-dimension code PDF417, QR sign indicating number etc., also very ripe to their recognition facility simultaneously, so in use, its privacy degrees relative with security a little less than.As bar code, bar code is made up of one group of regularly arranged bar shaped, space and corresponding character, represents the sign of certain information.The principal character of two-dimensional bar code is all to represent to have data message in level and vertical direction.And the some horizontal and vertical parity check code is a kind of novel coding, it be my company in conjunction with mathematics, cryptography, a kind of coding of self-defined establishment, the decoding difficulty is big, this horizontal and vertical parity check code is miniature arrangement simultaneously, at 5 * 5mm ²At least have more than 300 information point in the scope, its be difficult for to be decoded, and special invisible material processed in addition simultaneously becomes sightlessly, and can not be reprinted, be duplicated, and a kind of coding that safe class is high, thereby be applicable to the fields such as false proof, anti-falsifying that require secret.For strengthening the security that the some horizontal and vertical parity check code uses, can adopt infra-red material to make specialities, promptly in links such as printing, printings, will put the horizontal and vertical parity check code stealth, excite down shining of common and extraordinary light, human eye still can't be seen, can not be replicated or copy.

Fig. 1 has provided the shape of some horizontal and vertical parity check code.As seen from Figure 1, literal, figure and acoustic information become a horizontal and vertical parity check code by encoding process.The point horizontal and vertical parity check code seems rambling point by some to be formed, and in the alignment processes of these points, but contains corresponding literal, figure and acoustic information.

Contained information in this horizontal and vertical parity check code is according to the inverse operation process of cataloged procedure, by decoding, deciphering, again by graphics process and pronunciation circuit, with information reverting (Fig. 2).The theoretical foundation of Here it is knowledge and magnanimity anti-counterfeiting voice pen.

Summary of the invention

The utility model technical issues that need to address are, in known technology, one dimension or two-dimensional bar code had weakness such as easy recognition, transreplication, antifalsification difference, under the occasion that needs safety, maintains secrecy is inapplicable, in order to overcome these deficiencies, just need develop a kind of coding that is applicable to antifalsification, high safety, promptly put horizontal and vertical parity check code, thereby to its development reading device.The purpose of this utility model, provide a kind of recognition anti-counterfeiting voice pen, for realizing this purpose, the technical scheme that is adopted is as follows: a kind of recognition anti-counterfeiting voice pen, comprise recognition Antiforging pen urceolus, outside single-chip microcomputer and the audio processing equipment that connects, it is characterized in that, be equipped with in the recognition anti-counterfeiting voice pen urceolus pick-up lens, it in succession sensor, be connected to the image interface chip circuit, be connected to single-chip microcomputer through USB interface, after export after the Audio Processing.Described absorption camera lens includes camera lens, light-splitting processing assembly and the light source luminescent wavelength is had the special source of particular requirement, and the optical wavelength scope of this special source is at 750-1150nm.

The beneficial effect of this recognition anti-counterfeiting voice pen is, can put horizontal and vertical parity check code to stealth and carry out fast, accurately reads, and safety anti-fake performance and anti-replication performance are good.

Fig. 2 is recognition anti-counterfeiting voice pen profile synoptic diagram;

Fig. 3 is recognition anti-counterfeiting voice pen structure block diagram;

Fig. 4 is above-mentioned recognition anti-counterfeiting voice pen lens assembly annexation figure.

Embodiment

With reference to Fig. 1, the shape and the forming process thereof of expression point horizontal and vertical parity check code, wherein putting horizontal and vertical parity check code 1 is to count software by specific similar rambling a slice point that coding rule presented by calculating, and Fig. 2 a represents the appearance shape synoptic diagram of this product, and 2 is plastic casing among the figure.With reference to Fig. 2 b, expression recognition anti-counterfeiting voice pen is formed the block diagram of structure, among the figure as for side in the works be camera lens 3, it links to each other with sensor 4, be connected to image interface chip 5 and single-chip microcomputer 6 through sensor, the signal of handling delivered to the Audio Processing part by single-chip microcomputer.With reference to Fig. 3, be recognition anti-counterfeiting voice pen lens assembly annexation figure, the optical wavelength of indication special source among the figure, its scope is at 750-1150nm, and this special source promptly is the light source that the light source luminescent wavelength is had particular requirement.

Claims

1. distinguish anti-counterfeiting voice pen for one kind, comprise recognition Antiforging pen urceolus, outside single-chip microcomputer and the audio processing equipment that connects, it is characterized in that, be equipped with in the recognition anti-counterfeiting voice pen urceolus pick-up lens, it in succession sensor, be connected to the image interface chip circuit, be connected to single-chip microcomputer through USB interface, after export after the Audio Processing.

2. according to the described recognition anti-counterfeiting voice pen of claim 1, it is characterized in that described absorption camera lens includes camera lens, light-splitting processing assembly and the light source luminescent wavelength is had the special source of particular requirement, the optical wavelength scope of this special source is at 750-1150nm.
