Description
Technical field
The utility model relates to the preventing credit card embezzlement technology, but especially a kind of preventing credit card embezzlement device of photographic images.Be applicable to bank or ATM.
Background technology
Along with popularizing of computer technology, utilize the case of credit-card-related offenses also more and more, bank and public security department are also extremely urgent for the preventing credit card embezzlement Study on Technology.In existing preventing credit card embezzlement technology, using maximum is that password is set, and they have been proved to be insecure in actual use.In existing bank hardware facility, the multichannel video camera is housed, video camera links to each other with the Control Room of bank, the monitor staff monitors turnover, the comings and goings situation of personnel in the lobby on video screen, but it also exists randomness, be subjected to the restriction of camera angle, the scene of some particular importance is not taken the photograph on the contrary, each remittee can not fix a point, can not provide the strong evidence of wash rice clearly when getting in public security officer's investigation, in addition, contain much information, a large amount of video tapes are difficult to preserve, search, and general bank only preserved one month.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of easy for installation, preserve a large amount of pictorial informations with less memory capacity, picture is got (remittee) targetedly, but holding time length, high safety, can utilize the preventing credit card embezzlement device of the photographic images of existing supervisory control system.
The technical scheme that the utility model adopted is: but the preventing credit card embezzlement device of photographic images, has the multichannel video camera, the multichannel card reader, its design feature is that it also comprises the Card Reader detector, the video switch controller, monitoring host computer, be connected to video signal cable between video camera and the video switch controller, be connected to transmit line and received signal line between video switch controller and the monitoring host computer, be provided with the Card Reader detector between card reader and the monitoring host computer, its input links to each other with the card reader serial ports by digital signal line, and output is connected with monitoring host computer by differential signal line.
Described Card Reader detector comprises single-chip microcomputer, RS232 drive circuit, RS485 drive circuit, is connected to the RS232 drive circuit between single-chip microcomputer and the card reader, is connected to the RS485 drive circuit between single-chip microcomputer and the monitoring host computer.
The beneficial effects of the utility model are: volume is little, easy for installation, and memory capacity that can be less is preserved a large amount of pictorial informations, has saved memory space, has also prolonged the holding time; Security performance is strong, can utilize existing supervisory control system, this device can make credit card have recessive image information, in the use of credit card, promptly have in the existing supervisory control system of monitoring camera, add and plug this preventing credit card embezzlement device, just can take down this credit card user's digital image photo and storage in bank or ATM etc., simultaneously recording-related information such as service time place etc., improved the anti-performance of usurping of credit card greatly.
Description of drawings
Fig. 1 is a block diagram of the present utility model.
Fig. 2 is the circuit diagram of Card Reader detector in the utility model.
Embodiment
As shown in Figure 1, present embodiment comprises the video camera A～An of multichannel, card reader B～Bn, Card Reader detector I, video switch controller II and the monitoring host computer III of multichannel.Video camera and card reader are to utilize the existing equipment of bank.
Be connected by video signal cable 4 between video camera A and the video switch controller II, be connected with received signal line (RXD) 6 by the line that transmits (TXD) 5 between video switch controller II and the monitoring host computer III.Wherein, video switch controller II can adopt multi-channel video selection card (as NQ1602F, NQQ6408, NQQ1616) to realize.Digital image collection compression module and memory are housed among the monitoring host computer III, the digital image collection compression module can adopt image pick-up card (as Bt848) to add special image compressing card (as W9968CF), also can only adopt image pick-up card (as Bt848), realize compression by software algorithm.The compressed format of image can be JPEG, JPEG2000, wavelet compression, H.263, MPEG1, MPEG2.Memory in the monitoring host computer links to each other with digital image collection compressing card in the monitoring host computer by data/address bus, address bus and control bus, provide storage digital image information needed space, mainly adopt memories such as hard disk, digital-magnetic tape machine and CD to realize.
Video switch controller II and monitoring host computer III can be outsourcing pieces, the video camera A of video switch controller II and multichannel be connected and with being connected of monitoring host computer III all be the standard socket connection, those of ordinary skill in the art can both accomplish.
Shown in Figure 2 is that Card Reader detector I is housed between existing card reader B and monitoring host computer III, and the Card Reader detector mainly is made up of three chip blocks, comprises RS232 drive circuit I-2, single-chip microcomputer I-1, RS485 drive circuit I-3.Link to each other with RX digital signal line 7 serial ports between card reader B and the RS232 drive circuit I-2, link to each other with differential signal line 8 between RS485 drive circuit I-3 and the monitoring host computer III, be connected with bi-directional digital holding wire RX, TX between RS232 drive circuit I-2 and RS485 drive circuit I-3 and the single-chip microcomputer I-1.Two chip block RS232 drive circuits of drive circuit are finished the function that the RS232 conversion of signals becomes the RS485 signal with the RS485 drive circuit, single-chip microcomputer can adopt AVR90 series, 51 family chips, be used for detecting the triggering signal of card reader, and this signal is sent to monitoring host computer.
Workflow of the present utility model is: monitoring host computer III receives the signal of swiping the card that Card Reader detector I sends, be that control of video switch controller II locking sends the pairing rig camera A of card reader B that uses signal, carry out the selection output procedure of an analog video signal, digital image collection compression module among the monitoring host computer III carries out the digitalization compressed coding with the analog video signal of input, catch a series of digital image photo, be stored in the monitoring host computer in the lump together with all the other information of credit card.The staff can use special-purpose software to watch all users' of this credit card a series of digital image photos and relevant information on monitoring host computer, makes credit card have recessive image proof of identification, thereby guarantees its fail safe.
