Embodiment
Below, describe the present invention in conjunction with the accompanying drawings.
As shown in Figure 1, present embodiment provides a kind of switching circuit and the mobile phone that can be used as electron key.
Switching circuit comprises: be used for the NFC antenna 11 of receiving data information, the NFC chip 12 that is used for data processing and conversion that is connected with the NFC antenna, with NFC chip microprocessor linked 13 and the circuit control system 14 that is connected with microprocessor, this circuit control system 14 is by microprocessor 13 its connections of control.Present embodiment NFC antenna tranmitting frequency is 13.56MHz.
Wherein, circuit control system 14 comprises: triode 141, relay 142 and Circuits System 143, the base stage of triode 141 connects microprocessor 13, the grounded emitter of triode 141, the control contact of the collector connection relay 142 of triode 141, the normally opened contact of relay 142 is connected in the Circuits System 143.
Solicited message transmitting element 131 is used to send near the solicited message whether electron key is arranged the inquiry;
Select information transmitting unit 132, be used for after the response message that receives described request information, send the selection information of demand card ID;
Authentication information transmitting element 133 is used for after the response message that contains card ID that receives described selection information, sends the authentication information that includes random data;
Present embodiment also provides a kind of mobile phone that can be used as electron key, and this mobile phone comprises: baseband chip 23, NFC chip 22 that is used for data processing and conversion that is connected with baseband chip and the NFC antenna 21 that is used for receiving data information that is connected with the NFC chip.
Wherein, baseband chip 23 comprises:
Request response message transmitting element 231, be used for when receive whether the solicited message of electron key is arranged near the inquiry after, send and ask response message;
Select response message transmitting element 232, be used for after the selection information that receives demand card ID, send the selection response message that contains card ID;
Authentication response information transmitting element 234 is used to send the authentication response information after described coding unit is encoded.
In conjunction with shown in Figure 2, near real-time or every the solicited message whether electron key is arranged being used to inquire about by NFC chip and NFC antenna transmission at regular intervals of solicited message transmitting element in the microprocessor 13 in the switching circuit 131, for example REQUEST instruction.
When mobile phone enters in the switching circuit radiation field, because mobile phone NFC antenna 21 is in accepting state always, therefore, after mobile phone receives the described request information of switching circuit by NFC antenna 21, issue baseband chip 23 by NFC chip 22, request response message transmitting element 231 in the baseband chip 23 sends a request response message by NFC chip 22 and NFC antenna 21 again, tells switching circuit to have card to enter its radiation areas.
After switching circuit is received the request response message, knowing has card to enter its radiation areas, so the selection information transmitting unit 132 in the microprocessor 13 is selected the solicited message of this card again by NFC chip and NFC antenna transmission, for example SELECT instruction requires the other side that its card ID is sended over.
Mobile phone is given to baseband chip 23 by the NFC chip after receiving the selection solicited message by NFC antenna 21, and baseband chip 23 selects the response message that response message transmitting element 232 will contain mobile phone card ID to send to switching circuit by it.
