2nd, support the consensus standard for meeting：ESAM the and PSAM modules of ISO/IEC14443TypeA/TypeB, ISO7816 standard
Card；
3rd, the communication baud rate of RS232 communication interfaces is 57600bps or 115200bps；
4th, communication protocol can be customized according to customer requirement, increased the motility of card reader；
5th, the key load modes such as plaintext key, ciphertext key, key numbering are supported.
Description of the drawings
Fig. 1 is a kind of theory diagram of charging pile special-purpose radio-frequency card reader proposed by the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.
With reference to Fig. 1, a kind of charging pile special-purpose radio-frequency card reader, including CPU microcontrollers, card reader control chip, antenna,
PSAM interfaces, ESAM interfaces, display lamp, buzzer, RS232 communication interfaces, local upgrade interface, the model of CPU microcontrollers
For STM32F101, the contactless read-write card chip of model MFRC522 of card reader control chip, communication frequency are 13.56MHz,
PSAM interfaces, ESAM interfaces are respectively used to the PSAM and ESAM for reading ISO/IEC14443TypeA/TypeB, ISO7816 standard
Module card, the communication baud rate of RS232 communication interfaces is 57600bps, and the CPU microcontrollers control core with card reader respectively
Piece, PSAM interfaces, ESAM interfaces, RS232 communication interfaces, local upgrade interface are bi-directionally connected, the output of the CPU microcontrollers
End is connected with the input of antenna, display lamp, buzzer respectively.
Wherein CPU microcontrollers and card reader control chip are the cores of radio-frequency card reader, complete card behaviour for control
Make flow process；Display lamp using common light emitting diode be used for indicating operating status, buzzer for reminding to user operation,
Model KTT-5018A paster thin Buzzer.
After CPU microcontrollers receive the instruction of the operation sheet that host computer is sent, the instruction is converted to into card reader
Card reader control chip is issued in instruction to control chip accordingly, and operational order is converted to 13.56MHz's by card reader control chip
Radiofrequency signal is interacted with card, or passes through PSAM interfaces, ESAM interfaces and PSAM or ESAM cards in the way of wired
Interact.
Interactive instruction mainly has：Open antenna, card seeking, card is carried out read operation, to stick into row write operate, to sticking into value
Operation, closing antenna.
It is required for sending the access key of card when operation sheet, this card reader supports that plaintext key, ciphertext are secret
The modes such as key, key sequence number.And card reader general on market all only supports plaintext key, such key safety is inadequate.It is bright
Secretarial's key is that general card reader is all supported, he is that key is given Card Reader by communication protocol by host computer when card is accessed
Device, card reader this key go to access card, and such access mode key is easily stolen；Ciphertext key principle is with plain text
Mode it is identical, except for the difference that key be through encryption, even if be stolen to use, and ciphering process include algorithm and
The ciphertext factor, this is double to fill protection；Key numbering principle is identical with the mode of ciphertext key, except for the difference that algorithm and ciphertext because
Son is all unmodifiable, and equivalent to special key mode, and key numbering can reach 65535 kinds.And this card reader collection
Into above 3 kinds of key modes, general and customization can be used.
This card reader supports the operation of M1 cards and CPU card and ESAM and PSAM cards, possesses the special key configuration of client,
Ciphertext key is supported, customization communication protocol is supported, support that various protocols automatically switch, cost has advantage.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, should all be included within the scope of the present invention.
