The utility model collects a plurality of detecting meanses into a whole, can carry out high-precision complex detection for identity cards, has high intellectualized and automatic degree, can improve detecting accuracy, and has convenient operation.

Description

The ID card verification instrument

The utility model relates to the certificate detecting instrument, relates to a kind of ID card verification instrument specifically.

Current, I.D. is self-evident as its importance of certificate of people's life and work indispensability, and also just seem very important for the discriminating of the I.D. true and false, in the middle of prior art, the true and false of certificate mostly is to rely on manually to judge by rule of thumb or being equipped with simple supplementary instrument carries out authenticity, these supplementary instruments generally all are by the fluorescent lamp certificate to be shone, utilize the reflective observation color of ink or the reflectance of the reflective printing ink on the certificate to wait the true and false of distinguishing the discriminating certificate, because this identification of means mainly is to be judged by people's eyesight and experience, be subjected to artificial factor to cause error in judgement easily, accuracy rate is low, on the other hand, reflective printing ink is as general goods, buying in market easily makes forged certificate also more convenient, this forged certificate also causes omission by the discriminating of this detector easily, does not have the due effect of assessing instrument.

It is one that the purpose of this utility model provides the multiple identification of means of a kind of collection, and I.D. is carried out compound detection, thereby improves the ID card verification instrument of identifying accuracy rate.

In order to achieve the above object, the utility model adopts following structure, the utility model is by electronic rectifier, the luminescence-utraviolet pipe, alarm lamp, display, photosensitive probe, single-chip microcomputer, video camera and independent current source are formed, it is characterized in that: electronic rectifier (1) control luminescence-utraviolet pipe (2), I.D. is carried out reflective irradiation, be connected on single-chip microcomputer (6) input end many groups photosensitive probe (5) respectively the pros and cons of corresponding I.D. carry out reflected light and penetrate the light light signal collection and after photosignal conversion, return single-chip microcomputer (6) comparing analyzing and processing, carrying out the acousto-optic indication by pilot lamp (8) that is connected single-chip microcomputer (6) output terminal and alarm (7) reports to the police, and the Digital Video (3) that single-chip microcomputer (6) input end connects is carried out the picture signal collection to I.D. after single-chip microcomputer (6) processing and amplifying, show that by display (9) single-chip microcomputer (6) and pilot lamp (8) and the required operating voltage of alarm (7) are provided by independent current source.

Described photosensitive probe is made of photodiode cooperates resistance capacitance and photosignal conversion chip to form with amplifying triode photosignal change-over circuit.

Principle of work of the present utility model is as follows: I.D. is put into luminous being radiated on the I.D. front of instrument unlocking electronic rectifier control luminescence-utraviolet pipe, make reflective ink printing pattern and writing on the I.D. carry out reflective, offer an explanation the discriminate one's identification true and false of card of its color and reflectance by vision, simultaneously, the photosensitive probe that is arranged on I.D. pros and cons direction is by to the reflected light of I.D. with penetrate light and carry out sending single-chip microcomputer to carry out signal Processing behind the light signal collection, because the I.D. material therefor is a special paper, its reflection light quantity all is to have standard value with penetrating light quantity, and photosensitive probe is made up of photodiode triode and photosignal conversion chip, photodiode is with the reflected light that collects and penetrate light signal and amplify the opto-electronic conversion chip by triode and convert backspace single-chip microcomputer behind the electric signal to, compare analysis and juggling with the standard signal that is arranged in the single-chip microcomputer, then the result electric signal is exported, carrying out acousto-optic by on-off circuit control pilot lamp and loudspeaker shows, if the then normal pilot lamp of normal signal is glittering, if abnormal signal then alarm lamp is glittering, different audio communication signals is sent in loudspeaker cooperation simultaneously, high definition degree of the analysing video camera that connects on the single-chip microcomputer is then the facsimile signal collection on the I.D. and export on the display after the single-chip microcomputer processing and amplifying, can carry out vestige and identify that single-chip microcomputer and acousto-optic show that required working power is then provided by independent current source.

Because not only having adopted, the utility model utilize ultraviolet ray irradiation I.D. to differentiate that the aberration of reflective printing ink and reflectance detect principle, also adopted the reflective amount of utilizing photosensitive probe captured identity card paper or light transmission capacity and undertaken carrying out the structure that audio communication is reported to the police after the analyzing and processing by single-chip microcomputer, and assist in high definition degree of analysing video camera and carry out the picture and text display structure, the true and false that discriminates one's identification and demonstrate,prove, make the utility model integrate multiple detection architecture principle, can carry out the compound detection of pinpoint accuracy to I.D., intelligent, the automaticity height, can improve effectively and detect accuracy rate and easy and simple to handle, accommodation is extensive.

Below in conjunction with accompanying drawing in detail the utility model is described in detail.
