Abstract
The invention relates to the authentication and the printing of paper currency serial numbers. A CIS (contact image sensor) is adopted to scan the paper currency. High-efficiency videotext signal reshaping and compression, feature extraction and automatic identification and screening of network allow a microcontroller with low operational capability to extract and identify a character signal from image background effectively, so that a machine can identify and print the nominal amount and the serial number of the paper currency. Two independent identification CPUs are respectively aimed at deep color and light color images signals so as to effectively compensate for the difference of deep color and light color signals of the paper currency, thereby improving the recognition rate and the reliability. The CIS is installed in the paper currency passage of a bill counter, automatically identifies the new and old editions of paper currency, reads the serial number and the image signals, extracts 2 letters and 11 digital signals after the separation of the image signals, and shows the results and prints the serial number after the image signal compression and movement and the identification of letters or numerals.
Description
Technical field
The present invention relates to the counting field.
Background technology
Along with Chinese economic development, social status also constantly rises.Currency is also more and more paid attention to as the symbol status of a kind of national image of representative.Thereby the research of the identification of currency and application thereof are also just more and extremely more urgent.
Banknote is in circulation, and often the judgement because of counterfeit money causes dispute.For example, the Party A receives Party B's cash, in just finding counterfeit money is arranged afterwards, and the Party A can't prove that counterfeit money is exactly the Party B's this moment.If litigant's print record face to face when handing-over goes out the sequence number of all banknotes, problem has just solved.
Bank Clerk, ATM Automatic Teller Machine etc. if be equipped with banknote sequence number identification record equipment, when the counterfeit money dispute occurring, can provide admissible evidence, have both avoided dispute, have improved the credit rating of financial company again.
Departments such as finance, public security by the financial sector network, monitor the sequence number of each site circulation banknote for specific needs (for example searching the banknote of the blacklist on the sequence number).
Summary of the invention
In order to solve above technology, the present invention has adopted the scanning of CIS contact image sensor, facsimile signal shaping efficiently, compression, feature extraction and network are discerned screening automatically, make the general single chip of low arithmetic capability can make character signal effectively from image background, detach identification, make machine can discern and print the denomination and the sequence number of banknote.
The technology crux problem that the present invention solves is:
1) adopts CIS contact image sensor and general single chip as image capture and signal processing unit, constitute anti-counterfeit recognition system cheaply.
2) single-chip microcomputer is made the synchronously mutual school of double-channel signal processing mode, effectively reduces the deep or light identification influence that causes of image printing.
3) facsimile signal shaping efficiently, compression, feature extraction and network are discerned screening automatically, make the general single chip of low arithmetic capability can make character signal effectively detach identification from image background, machine can be discerned print banknote denomination and sequence number.
4) waveform Dynamic Tracing Technology and trend prediction determination methods effectively reduce the influence of light and device aging, promote false proof and discrimination.
The invention has the beneficial effects as follows that because the present invention can be to the banknote number storage, every bundling note machine can give unique serial number, the whole bundle of banknote deposits warehouse of bank in.In case rob the bank, armoured van, or crime such as kidnapping, bank and other financial mechanism can propose every number of being robbed according to unique serial number of every bundling note machine and be announced, the offender is formed deterrence.

Embodiment
Light source among the present invention (1) is used to read bank note (2) number information, can adopt photovalve.Consider banknote number position, and the workload of arrangement banknote, scan controller needs respectively to install 1 in banknote homonymy the right and left number position, can scan whole numbers like this.Employing is ripe, stable, 51 series are made core CPU cheaply, system adopts a plurality of CPU structures, function modoularization, each CPU undertakes function separately separately, each CPU usefulness is performed to ultimate attainment, finish the digital operation workload of complexity such as the Flame Image Process of having only large complicated DSP just can finish, letter identification, digit recognition.2 groups of scanister are installed on paper money counter, one group be positioned at paper money counter send paper money and the top that goes out the paper money position intermediate, another group is positioned at paper money counter and send paper money and go out below, paper money centre position.
Adopt two independent identification CPU respectively to deep or light different picture signal, effectively compensate the deep or light difference signal of bank note, improved discrimination and reliability.
The CIS contact-type image sensor is installed in the banknote path of paper money counter, automatically the new old edition of identification reads the series number picture signal, separate through picture signal, extract 2 letters and 11 digital signals, then through picture signal compression and mobile and letter identification or digit recognition, last display result and printout.
Claims (4)
1, a kind of discriminating of paper money sequence number and printing, it comprises mechanical hook-up, housing, counting control circuit, output unit, also include scanister, banknote number storage unit, it is characterized in that the CIS contact-type image sensor is installed in the banknote path of paper money counter, automatically the new old edition of identification reads the series number picture signal, separate through picture signal, extract 2 letters and 11 digital signals, then through picture signal compression and mobile and letter identification or digit recognition, last display result and printout.
2, the discriminating of paper money sequence number according to claim 1 and printing is characterized in that: the installation site of described scanister is corresponding with banknote front number, about each 1.
3, the discriminating of paper money sequence number according to claim 1 and printing, it is characterized in that: scanister is two pairs, the wherein a pair of paper money counter that is positioned at send paper money and the top that goes out paper money centre position banknote, and another send paper money and the below that goes out paper money centre position banknote to being positioned at paper money counter.
4, the discriminating of paper money sequence number according to claim 1 and printing is characterized in that: this paper money counter also comprises reading in sequence number picture signal (3) unit, CPU image scanning control signal (4) unit, image binaryzation processing unit (5), the deep or light threshold adjusting of image (6), CPU memory image unit (7), number identification (8), numerical signal separation cuts (9), sequence number output and printing (11) of connecting successively.
