Summary of the invention
A kind of IC-card automatic switching method of the present invention is integrated the IC-card card reader by control circuit, and then has been made things convenient for use, has prolonged the serviceable life of IC-card card reader.
The technical solution adopted for the present invention to solve the technical problems is: set up the passage control switching circuit that U1-U6 forms on card reader circuit, 19 pin that connect chip U2 behind 1 pin of 1 pin of its chips U1 chip U4 in parallel, chip U2 connects serial ports J1 and chip U3, chip U1 is connected deck ID1 and ID2 with U4 respectively by socket J2, main frame issues the passage control switching circuit that control command forms for chip U1-U4 by serial ports, and control circuit is connected the passage between card reader and the object card;
Passageway switching method between card reader and the object card may further comprise the steps:
A, main frame issue control command by serial ports J1;
After B, chip U2 obtain passage and switch to deck ID1 order, the level of 19 pin is dragged down, chip U1 and U4 are communicated with pin 1A and 1B1, pin 1A and 1B2 disconnect, thereby C2 connection SMO_C2, C3 is communicated with SMO_C3, and C4 is communicated with SMO_C4, C6 is communicated with SMO_C6, C7 is communicated with SMO_C7, and C8 is communicated with SMO_C8, and PRES is communicated with SMO_PRES, when SM_SW was low, SM_VCC was communicated with SMO_C1;
C, make the signal communication of deck ID1 and socket J2.
Passageway switching method between card reader and the object card may further comprise the steps:
A, main frame issue control command by serial ports J1;
After B, chip U2 acquisition passage switches to deck ID2 order, the level of 19 pin is drawn high, chip U1 and U4 are communicated with pin 1A and 1B2, pin 1A and 1B1 disconnect, thereby C2 connection SM1_C2, and C3 is communicated with SM1_C3,
C4 is communicated with SM1_C4, and C6 is communicated with SM1_C6, and C7 is communicated with SM1_C7, and C8 is communicated with SM1_C8, and PRES is communicated with SM1_PRES, and when SM_SW was low, SM_VCC was communicated with SM1_C1;
C, make the signal communication of deck ID2 and socket J2.
Excellent beneficial effect of the present invention is: set up the passage control switching circuit that U1-U6 forms on card reader, do not increasing the IC card reader and revising under the situation of application program, realize the switching of system manager's IC-card, various mandate IC-card and all types of user card by the passage control switching circuit, reduce IC-card plug number of times, reduce window services personnel's working pressure, reduced use cost, increased work efficiency, facilitated for user and attendant.
