Embodiment
With embodiment the technical scheme that the present invention can prolong the non-contact card system of service range is elaborated below.
With reference to Fig. 1, the non-contact card system that the present invention can prolong service range by card reader, the additional reader and the non-contact card that are used to prolong the Card Reader distance form.Wherein, card reader is the master control end of system, is responsible for sending the Card Reader order to additional reader, and the data that receive non-contact card from additional reader.Additional reader receives the order of card reader, finishes the reading writing working to non-contact card.Between card reader and the additional reader with the mode swap data of radio communication.Contactless IC card is used to deposit user profile, account information etc.This card has been selected the Mifare series contactless IC card of Philips company.
With reference to Fig. 2, card reader is made up of first wireless data transfer module, RS232 module and first controller etc.This card reader has kept stronger upgrading ability, can add time block, memory module, human-computer interaction module etc. as required easily.First controller is mainly finished work such as the control and management of each module and encryption, deciphering.Wireless data transfer module is an existing product, selects to have the Transistor-Transistor Logic level interface serial data transmission rate 9600bps, the module of aerial speed 38400bps.PC interface module U4 is the RS232 interface module, as the interface module of communicating by letter with host computer, can communicate with PC when being necessary.
With reference to Fig. 3, additional reader is made up of card reading module, second wireless data transfer module and second controller etc.Wherein card reading module is the MF RC500 of Philips company, and MF RC500 is applied to a member in the high integrated Card Reader IC series in the 13.56MHz contactless communication.This Card Reader IC series has been utilized advanced modulation and demodulation notion, fully-integrated under 13.56MHz all types of passive contactless communication modes and agreement.Second wireless data transfer module is identical with first wireless data transfer module.Second controller is responsible for control and management card reading module, second wireless data transfer module, and the data that read are carried out suitable processing.
The following describes the course of work that the present invention can prolong the non-contact card system of service range.
At first, data in the IC-card are through ovennodulation, become simulating signal and signal is launched, receive by card reading module antenna among Fig. 6, the simulating signal through ovennodulation that antenna receives is finished demodulation by the card reading module among Fig. 5, digital data transmission after the demodulation is given the controller among Fig. 4, and controller is transferred to wireless data transfer module among Fig. 7 with signal wirelessly by wireless data transfer module among Fig. 6, is finally received by Fig. 8 middle controller.So, finished signal and snapped into the transmission of card reader from contactless ic, with reference to Fig. 4 to Fig. 7, its detailed process is:
1. signal snaps into the process of card reader from contactless ic: the signal through ovennodulation that contactless IC card sends is received by card reading module antenna shown in Figure 6, be input to No. 29 pins of card reading module U2 (MFRC500) among Fig. 5, signal by demodulation, is transferred to 32～No. 39 pins of data bus of the second controller U1 (SST89E564RD) among Fig. 4 by 13～No. 20 pins of data bus of card reading module U2 (MFRC500) in card reading module U2 (MFRC500).The second controller U1 (SST89E564RD) is again with No. 11 pin outputs of data by the second controller U1 (SST89E564RD), be transferred to No. 11 pins of the first controller U3 (STC89LE58) among Fig. 7 by means of wireless data transfer module, handle by the first controller U3 (STC89LE58).
2. the process of signal from the card reader to the contactless IC card: among Fig. 7 the first controller U3 (STC89LE58) with data by No. 13 pins output, be transferred to No. 10 pins of the second controller U1 (SST89E564RD) among Fig. 4 by means of wireless data transfer module, the second controller U1 (SST89E564RD) is again by 32～No. 39 pins of data bus, 13～No. 20 pins of data bus with data transmission card reading module U2 (MFRC500) in Fig. 5, data are modulated in card reading module U2 (MFRC500), by card reading module U2 (MFRC500) No. 5 and No. 7 pins are transferred to by card reading module antenna shown in Figure 6 again, are received by contactless IC card afterwards.
Can prolong among the embodiment of non-contact card system of service range in the present invention, between card reader and contactless IC card, increased an additional reader that volume is little, by this additional reader as intermediary, make card reader and the non-operating distance that connects card improve the several number magnitude, respond well.This system does not change the principle of work of contactless IC card, has just prolonged operating distance between card reader and the contactless IC card by additional reader with auxiliary communication.Additional reader receives the order from card reader, the read-write contactless IC card, mutual to carry out between the mode of radio communication and the card reader, make card reader on 100 meters even farther distance, read and write contactless IC card, improve result of use greatly, obtained gratifying effect.
The present invention can prolong the non-contact card system of service range, when not using additional reader, does not influence the use of original card reader, still can operate as normal.
