Technical field
The utility model belongs to the technical field of the identity of utilizing I.D. identification I.D. possessor, is specifically related to a kind of easy China second-generation identity card recognition device.
Background technology
The use of current radio-frequency card is commonplace, and be widely used in various occasions such as gate inhibition, work attendance, consumption, when using radio-frequency card, mainly utilize the content of storing in the radio-frequency card sign as unique identity of possessor, such as the MF1 card is exactly this class card, but adopt this class card at first to need the possessor to purchase this type of card, therefore increased possessor's expenditure in order to the identity of distinguishing the possessor.China second-generation identity card is popularized at present, China second-generation identity card also is a kind of of radio-frequency card, but data such as the name of storing in the China second-generation identity card, ID (identity number) card No. are encrypted, therefore discern each holder if utilize data such as name in the China second-generation identity card, ID (identity number) card No., just need configuration to contain the special-purpose card reader of safety encipher module, therefore existing China second-generation identity card identification equipment price height, volume is big, power consumption is big, and be not easy to use.
Summary of the invention
One of the purpose of this utility model provides a kind of China second-generation identity card recognition device, and it is simple in structure, and is easy to use, and cost and power consumption are all lower.
For achieving the above object, the utility model has adopted following technical scheme: a kind of China second-generation identity card recognition device, this recognition device comprises controller, is provided with the identification module that China second-generation identity card is discerned in the controller.
The utility model can also be achieved by following measure:
Described identification module comprises by sky alignment China second-generation identity card and sends recognition command and replying of China second-generation identity card dealt with the Card Reader chip.
Described Card Reader chip carries out identification by the ID number possessor to China second-generation identity card of the RFID chip in the identification China second-generation identity card.
Described controller is that model is the single-chip microcomputer of MSP430F2252, the Card Reader chip is the AS3910 card reader that satisfies Austrian Microtronic A/S of ISO14443B standard, antenna is the PCB antenna, and described single-chip microcomputer MSP430F2252 and described AS3910 card reader are by the Serial Peripheral Interface (SPI) communication.
Another purpose of the present utility model provides a kind of recognition methods of adopting above-mentioned recognition device, and the technical scheme of this recognition methods may further comprise the steps:
Step 101, controller control Card Reader chip sends the REQB order by sky alignment China second-generation identity card, and the Card Reader chip is given controller the acknowledgement transmissions of the China second-generation identity card of receiving by antenna, if China second-generation identity card is replied correctly, then carry out next step, otherwise repeating step 101;
Step 102, controller control Card Reader chip sends the ATTRIB order by sky alignment China second-generation identity card, the Card Reader chip is given controller the acknowledgement transmissions of the China second-generation identity card of receiving by antenna, after if China second-generation identity card is replied correct and is entered state of activation, then carry out next step, otherwise return step 101;
In the described step 103, read ID number order of the RFID chip in the China second-generation identity card, its data are 0x00 0x36 0x00 0x00 0x08.
The beneficial effects of the utility model are: because ID number of the RFID chip in each China second-generation identity card all is unique, the ID of each I.D. number all inequality, so therefore each ID number just corresponding accredited personnel utilize the technology of ID number identification holder of China second-generation identity card just can be applied to various occasions such as work attendance, gate inhibition, consumption.The utility model has the advantages that the China second-generation identity card that can fully use the resident to have, and do not need the resident to buy extra radio-frequency card in addition, and the utility model does not need to use the special-purpose card reader of China second-generation identity card to go enciphered messages such as the name of reading encrypted, identification card number yet, simultaneously the utility model have also that circuit is simple, cost and power consumption advantage all lower and easy to use.
