Abstract
The utility model provides a multi-functional composite card reader, comprising a CPU (central processing unit), a fingerprint scanner, a Flash storage module, a radio frequency card-reading module, an interface control module and a terminal safety control PSAM (pilot symbol assisted modulation) card module, wherein the CPU is connected with the fingerprint scanner, the Flash storage module, the radio frequency card-reading module, the interface control module and the terminal safety control PSAM card module respectively by communication control wires. In the utility model, a CPU card technology and the fingerprint identification technology can be integrated, so as to achieve the purposes of reading the CPU card with 13.56MHz and collecting and identifying fingerprint of a human body on the same card reader, bring great convenience for management efficiency of users and saving the manufacturing cost simultaneously.
Description
Technical field
The utility model relates to reader device, relates in particular to a kind of multi-functional compound card reader.
Background technology
Card reader in the market can be divided into fingerprint identifying class and RF identification class (RFID) card reader substantially.Fingerprint identifying class card reader is suitable for the higher occasion of security requirement, can utilize people's biological characteristic to realize the same purpose of the testimony of a witness.RF identification class card reader card reading speed is fast, is usually used in public transport, gate inhibition, the attendance checking system.
But fingerprint identifying class and RF identification class card reader all can only read in single identification usually, and user such as needs use the card reader of two kinds of functions, just must buy two complete equipments, management respectively.Therefore, increase extra expenses on the one hand, also wasted the time simultaneously, reduced the efficiency of management.
Summary of the invention
The purpose of the utility model is to provide a kind of multi-functional compound card reader of simple in structure, convenient management.This card reader can realize the collection and the identification of reading the CPU card and carrying out somatic fingerprint, greatly facilitates user's the efficiency of management, has also practiced thrift cost of manufacture simultaneously.
The purpose of the utility model realizes through following technical scheme.
A kind of multi-functional compound card reader; Comprise: CPU, fingerprint acquisition instrument, Flash memory module, radio frequency card reading module, interface control module and terminal security control PSAM card module, said CPU is connected with fingerprint acquisition instrument, Flash memory module, radio frequency card reading module, interface control module and PSAM card module respectively through the Communication Control line.
Preferably, said Flash memory module comprises the public area that is used to store user basic information and is used to store the closed security zone of finger print data, fingerprint application program.
Preferably, said interface control module specifically comprises: USB interface, RS485 interface and Wiegand26/34 interface.
Preferably, also comprise the Anneta module that links to each other with the radio frequency card reading module.
The utility model embodiment compared with prior art; Beneficial effect is: the utility model is through combining CPU card and two kinds of technology of fingerprint recognition together; Thereby realize that the CPU card that same card reader both can read 13.56MHz also can carry out the collection and the identification of somatic fingerprint; Greatly facilitate user's the efficiency of management, also practiced thrift cost of manufacture simultaneously.
Description of drawings
Fig. 1 is the utility model hardware principle block diagram.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also shown in Figure 1; Comprise: CPU, fingerprint acquisition instrument, Flash memory module, radio frequency card reading module, interface control module, power module and terminal security control (PSAM card) module, said CPU is connected with fingerprint acquisition instrument, Flash memory module, radio frequency card reading module, interface control module and terminal security control (PSAM card) module respectively through the Communication Control line.The radio frequency card reading module also links to each other with Anneta module.
Wherein, the Flash memory module comprises public area and closed security zone again, and the public area is used to store user basic information, and the closed security zone is used to store finger print data, fingerprint application program.
Wherein, interface control module specifically comprises: USB interface, RS485 interface and Wiegand26/34 interface.
Its principle of work is: behind the electrification reset, CPU is to fingerprint acquisition instrument and the initialization of radio frequency card reading module, and CPU takes out key from the PSAM card, be stored in the storer of radio frequency card reading module.The data of fingerprint collecting and 13.56MHz CPU card read and adopt interrupt mode to carry out; When fingerprint acquisition instrument has finger print data collected; Fingerprint acquisition instrument has been gathered completion through interrupting informing the CPU finger print data; Have no progeny during CPU receives and take out fingerprint image from fingerprint acquisition instrument, through after the Flame Image Process be stored in closed security zone fingerprint template in the Flash memory module and carry out identification and the coupling of 1:1 or 1:N; When the 13.56MHz card is swiped the card; The radio frequency card reading module is used from the key of CPU acquisition the data of reading the 13.56MHz IC-card is deciphered; Data storage after the deciphering is in the storer of radio frequency card reading module; CPU has brushing card data with interruption form notice, and CPU takes out the card relevant information from the storer of radio frequency card reading module.According to the different working pattern, output card relevant information, fingerprint number information etc.
This card reader is mainly used in systems such as gate inhibition, parking lot, consumption or work attendance.Concrete parameter is following:
IC-card technology: Mifare1 (ISO14443A 13.56MHz);
Card Reader distance: be superior to 6cm;
Communication interface: Wiegand 26/34, RS-485 and USB2.0;
Processing capacity: fingerprint: 3000 pieces, Mifare1 card: 3000;
Working method: single deck tape-recorder, single fingerprint and card+fingerprint mode;
The identification response time: less than 1.5 seconds;
Accuracy of system identification (FAR): < 0.001 % (safe class is 4 o'clock);
Refuse sincere (FRR): < 0.1 % (safe class is) at 4 o'clock;
Safe class: 1 ~ 5 grade, can be provided with;
Working temperature :-10oC ~+70 oC;
Working relative humidity: 10% ~ 90%;
Protection class: IP54;
Shell: PC/ABS plastics;
WV: DC7.5V ~ 15V ± 5%;
Working current :≤300mA;
Antistatic interference: 15kV.
This card reader combines CPU card and two kinds of technology of fingerprint recognition together, thereby realizes that the CPU card that same card reader both can read 13.56MHz also can carry out the collection and the identification of somatic fingerprint, greatly facilitates user's the efficiency of management, has also practiced thrift cost of manufacture simultaneously.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
