Description
Technical field
The present invention relates to ATM ATM (Automatic Teller Machine), particularly relate to the cash-out movement that can identify crown word number in a kind of ATM ATM (Automatic Teller Machine) and crown word number identification method thereof.
Background technology
In the financial industry such as bank, ATM ATM (Automatic Teller Machine) has obtained and has widely used, its convenient, efficient Self-Service while alleviating bank counter service pressure, also with easy to operate and fast receive praises from customers.
Present stage, ATM (Automatic Teller Machine) has been a kind of high-tech product integrating computer technology, network technology, mechanical & electrical technology, automatic control technology, is the key equipment that bank realizes Self-Service.ATM ATM (Automatic Teller Machine) can realize operations such as withdrawing deposit, deposit, inquire about, change password and transfer accounts.
Because domestic cash flow flux is increasing, along with the frequent use of ATM ATM (Automatic Teller Machine), the dispute of various ATM note output is also more and more frequent, and extraction number as less than desirable in note output amount, note output amount are greater than in the extraction number of needs or note output and occur counterfeit money etc.Especially counterfeit money dispute, note output amount totals is only had because current ATM prints in strip, there is no other more effective note output records, as banknote version, bill crown word number etc., when getting counterfeit money in ATM, always each sticks to his own version or argument for bank and remittee, remittee is always difficult to prove that the counterfeit money in hand comes from ATM, be difficult to evidence obtaining, cannot examine at all, therefore substantially cannot solve the dispute that ATM meets with counterfeit money at present.
Summary of the invention
The present invention mainly solves original ATM and only has note output amount totals, there is no other more effective note output records such as banknote version, bill crown word number, meet with counterfeit money and be difficult to evidence obtaining, cannot examine at all, cause and be difficult to solve the technical matters that ATM meets with the dispute of counterfeit money; A kind of cash-out movement and the crown word number identification method thereof that can identify crown word number are provided, it can record the crown word number of each banknote in the every transaction of ATM, when bank receive holder meet with counterfeit money complain time, the bill crown word number that then can record according to ATM carries out examining and tracing, confirm whether counterfeit money comes from bank, thus the counterfeit money dispute of ATM is readily solved.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: the cash-out movement that can identify crown word number of the present invention, cash-out movement is arranged in ATM, bill crown word number recognition device is provided with in described cash-out movement, described bill crown word number recognition device comprises contact-type image sensor, analog-to-digital conversion module, Flash module and programmable gate array, Flash module is connected with programmable gate array, the data output end of described contact-type image sensor is connected with the data-interface of programmable gate array through analog-to-digital conversion module, the control signal end of contact-type image sensor is connected with the data-interface of programmable gate array, the USB interface of programmable gate array is connected with the USB interface of the industrial control host of ATM, described contact-type image sensor is arranged in the money transmitting channel of described cash-out movement.ATM is when note output, and banknote is passed by the money transmitting channel of cash-out movement, and the banknote of all processes scans down by the contact-type image sensor be arranged in money transmitting channel, and by image data transmission to programmable gate array.Programmable gate array both carried out logic control to contact-type image sensor, again slant correction is carried out to the view data obtained, denoising, luminance proportion, binaryzation, the pre-service such as enhancing and feature extraction, obtain bill crown word number pictorial information to be identified, also can according to the characteristic information of the length and width of banknote picture and papery, identify denomination and the version of banknote, these information flow to the industrial control host of ATM in the lump, by industrial control host, the identification of OCR algorithm is carried out to obtain crown word number to bill crown word number picture, and by crown word number and with the picture of crown word number together with the note output time, note output account, banknote denomination and version are preserved in a hard disk in the mode of database in the lump, and every process and output can be carried out according to the different demands of Ge Jia bank to obtained data.Due to 10 crown word number of banknote, the same with the identification card number of people, there is uniqueness, when therefore depositing and withdrawing in ATM, the crown word number of often opening banknote is recorded exactly, just can follow the trail of source and the whereabouts of each banknote.When bank receive holder meet with counterfeit money complain time, then the bill crown word number that can record according to ATM carries out examining and tracing, and confirms whether counterfeit money comes from bank, thus the counterfeit money dispute of ATM is readily solved.On the other hand, once there occurs the malignant events such as robbery, knowing again the serial number of the stolen banknote robbed, then the bill crown word number database by setting up, following the tracks of the cash lost quickly and easily, giving a clue for solving a case.
As preferably, described bill crown word number recognition device comprises digital signal processor, memory module and microprocessor, memory module is connected with digital signal processor, first bus interface of digital signal processor is connected with the bus interface of described programmable gate array, second bus interface of digital signal processor is connected with the bus interface of described microprocessor, and the USB interface of microprocessor is connected with the USB interface of the industrial control host of ATM.In the technical program, the bill crown word number pictorial information to be identified obtained after programmable gate array pre-service is not transferred to industrial control host, but is transferred to digital signal processor, to reduce the workload of industrial control host.Digital signal processor carries out OCR identification to bill crown word number pictorial information by fuzzy algorithm, export crown word number and picture, also can according to the characteristic information of the length and width of picture and papery, identify denomination and the version of banknote, these data messages send industrial control host by microprocessor to by USB interface again, industrial control host can first by the denomination of the picture that receives and crown word number and banknote, version is together with the note output time, note output account is preserved in a hard disk in the mode of database in the lump, and every process and output can be carried out according to the different demands of Ge Jia bank to obtained data.Meanwhile, microprocessor carries out logic control to programmable gate array and digital signal processor, ensures system worked well.
