Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 4, the card reading module of the many smart cards of a kind of compatibility that the utility model discloses, comprises MCU processor 1, ID induction module 2 and IC induction module 3.
ID induction module 2 and IC induction module 3 are electrically connected alternately with MCU processor 1 respectively, i.e. ID induction module 2 and IC induction module 3 and MCU processor 1 information mutual communication.The card number information that ID induction module 2 reads ID card transfers to MCU processor 1, and the card number information that IC induction module 3 reads IC-card transfers to MCU processor 1; The work of MCU processor 1 control ID induction module 2 and IC induction module 3.
ID induction module 2 and IC induction module 3 are connected to antenna (21,31).ID induction module 2 comprises oscillatory circuit, amplifying circuit etc., provides the radiofrequency signal required for ID card, and read ID card information, ID induction module 2 is prior art, and its concrete structure does not repeat herein.
IC induction module 3 comprises IC Card Reader chip, provides the radiofrequency signal required for IC-card, reading and writing IC card information, and IC induction module 3 is prior art, and its concrete structure does not repeat herein.
MCU processor 1 comprises single-chip microcomputer and control switching circuit, for the information of reading process ID induction module 2 and IC induction module 3, for the working hour of control ID induction module 2 and IC induction module 3, for analyzing the various cards that IC induction module 3 reads.
The utility model ID induction module 2 is for responding to the information of ID class card as ID card, IC induction module 3 is for responding to the information of IC class card, as nfc card, IC-card, the ID card and cell phone intelligent paste card etc., the work of MCU processor 1 control ID induction module 2 and IC induction module 3, MCU processor 1 controls to switch ID induction module 2 and IC induction module 3 Card Reader, as shown in Figure 4, thus various contactless card can be read, use more for convenience.
Radiofrequency signal due to the induction antenna 21 of ID induction module 2 can disturb the induction antenna 31 of IC induction module 3, cause Card Reader mistake, need employing two induction module time-sharing work patterns, namely when ID induction module 2 works, IC induction module 3 is invalid, and when IC induction module 3 works, ID induction module 2 is invalid, two kinds of Card Reader patterns can switch once for 0.25 second, and handoff procedure as shown in Figure 2.
ID card coded format 5 byte, MCU processor 1 directly reads ID card number by ID induction module 2.
IC-card belongs to category-A card; Nfc card belongs to category-A card; I.D. belongs to category-B card; Mobile phone string number same nfc card; Company of handset IC pastes the same IC-card of card.Because the coded format of various card is different, need to switch, MCU processor 1 first switches IC induction module 3 to category-A card Card Reader mode detection, has signal just to read card number information according to category-A card agreement; During category-A card Card Reader mode detection no signal, MCU processor 1 switches IC induction module 3 to category-B card Card Reader pattern, has signal just to read card number information according to B class card agreement; Switchback category-A card Card Reader pattern during category-B card Card Reader mode detection no signal, as shown in Figure 3.
The foregoing is only preferred embodiment of the present utility model, not to the restriction of this case design, all equivalent variations done according to the design key of this case, all fall into the protection domain of this case.
