Fig. 5 shows the schematic flow sheet according to the motion detection process of being carried out by motion detector of one embodiment of the present of invention.As shown in Figure 5, after motion detector 27 was activated, detecting unit 274 obtained the current a plurality of induced signals (step S501) that produce of a plurality of NFC induction antennas from NFC induction antenna array 272.
Then, detecting unit 274 calculates these a plurality of induced signals signal intensity (step S503) separately.
Detecting unit 274 judges in the signal intensity of these a plurality of induced signals that the signal intensity of at least one induced signal whether is more than or equal to predetermined signal strength threshold value T (step S505).This predetermined signal strength threshold value T equals that NFC card 10 has entered the induction range of a NFC induction antenna but the signal intensity of the induced signal that the NFC induction antenna produces when being positioned at the edge of this induction range.If the signal intensity of at least one induced signal is more than or equal to this predetermined signal strength threshold value T, show that then NFC card 10 has begun action (movement) above NFC induction antenna array 272, otherwise show that NFC card 10 does not also begin action above NFC induction antenna array 272.
If the determination result is NO for step S505, that is: NFC card 10 does not also begin action above NFC induction antenna array 272, and then detecting unit 274 enters waiting status, and this pending state will continue predetermined time interval (step S507).
After this pending state finished (namely continued should predetermined time interval), motion detection process turned back to step S501.
If the judged result of step S509 is yes, that is: NFC card 10 has begun action above NFC induction antenna array 272, and then detecting unit 274 obtains the current a plurality of induced signals (step S509) that produce of a plurality of NFC induction antennas from NFC induction antenna array 272.
Then, detecting unit 274 calculates these a plurality of induced signals signal intensity (step S511) separately.
Detecting unit 274 judges that whether each of signal intensity of these a plurality of induced signals is less than this predetermined signal strength threshold value T (step S513).If each of the signal intensity of these a plurality of induced signals is less than this predetermined signal strength threshold value T, showing then that NFC card 10 moves above NFC induction antenna array 272 finishes, otherwise shows that NFC card 10 also continues action above NFC induction antenna array 272.
If the determination result is NO for step S513, that is: NFC card 10 also continues action above NFC induction antenna array 272, then detecting unit 274 is selected in these a plurality of NFC induction antennas and the corresponding NFC induction antenna of induced signal with maximum signal, as NFC card 10 current the induction antenna of process, i.e. NFC card 10 current residing positions (step S515).
Then after the sign that is identified at the last NFC induction antenna of selecting of the NFC induction antenna of detecting unit 274 these selections of storage (step S517).Sign for the NFC induction antenna of selecting for the first time is stored in first position.
Then, detecting unit 274 enters waiting status, and this pending state will continue predetermined time interval (step S519).
After this pending state finished (namely continued should predetermined time interval), motion detection process turned back to step S509.Here, beginning to turn back to step S509 to the rear motion detection process of this pending state end from step S509 is an assay intervals.
If the judged result of step S513 is yes, that is: NFC card 10 moves above NFC induction antenna array 272 and finishes, and then detecting unit 274 is arranged (step S521) according to storage order to the sign of the NFC induction antenna stored.
At last, the output unit of detecting unit 274 is exported the sign of the NFC induction antenna after this arrangement as the action (step S523) of NFC card 10.
Although it will be appreciated by those skilled in the art that in this embodiment, sequentially represent each NFC induction antenna on the movement locus of NFC card with the front and back of memory location by the precedence of NFC card process, yet the present invention is not limited thereto.For example, in other embodiments of the invention, can to selecteed NFC induction antenna distribute an expression its by the NFC card the mark of precedence of process, this mark can be this selecteed time of NFC induction antenna, which selecteed NFC induction antenna etc., and the sign of this mark with this selecteed NFC induction antenna stored explicitly, like this, the sign that can arrange the NFC induction antenna of storing based on the precedence of the represented NFC card process of this mark, and the sign of the NFC induction antenna after arranging like this is output as the action of NFC card 10.
Fig. 6 shows the schematic flow sheet according to the action password setting up procedure of one embodiment of the present of invention.
As shown in Figure 6, at first, read write line 20 is set to move password pattern (step S600) is set.
Then, when the user is holding NFC card 10 near read write line 20, and when read write line 20 detected NFC card 10 and enters its induction range, the controller 23 of read write line 20 was enabled motion detector 27, and sent " please input action password " information (step S603) to indicator 29.
Then, after the information of receiving self-controller 23, indicator 29 shows this reception information (step S606).
When the user is holding the action of NFC card 10 control and display password above motion detector 27, motion detector 27 detects the action of NFC card 10 by the execution action testing process, and controller 23 (step S609) is exported in the action of the NFC card 10 that detects.What here, motion detector 27 was performed is motion detection process shown in Figure 5.
Controller 23 is stored in (step S612) in the storer 25 to the action of the NFC card 10 of motion detector 27 outputs.
Then, controller 23 sends " please again input action password " information (step S615) to indicator 29.
After the information of receiving self-controller 23, indicator 29 shows this reception information (step S618).
When the user is holding NFC card 10 again above motion detector 27 during the action of control and display password, motion detector 27 detects the action of NFC card 10 by the execution action testing process, and controller 23 (step S621) is exported in the action of the NFC card 10 that detects.What here, motion detector 27 was performed is motion detection process shown in Figure 5.
After the action of the NFC card 10 of receiving motion detector 27 output, the action that controller 23 is judged the current NFC card 10 of receiving be stored in storer 25 in the action whether identical (step S624) of NFC card 10.For example, if the action of the current NFC card 10 of receiving is according to the sign of the NFC induction antenna of following arrangement " 1,2,3,5,7,8 and 9 ", and the action that is stored in the NFC card 10 in the storer 25 is the sign " 1,2,3,5,7,8 and 9 " according to the NFC induction antenna of following arrangement, and then the action of this NFC card 10 of twice is identical.Again for example, if the action of the current NFC card 10 of receiving is according to the sign of the NFC induction antenna of following arrangement " 1,2,3,5,7,8 and 9 ", and the action that is stored in the NFC card 10 in the storer 25 is the sign " 1,2,3,5,9,8 and 7 " according to the NFC induction antenna of following arrangement, and then the action of this NFC card 10 of twice is not identical.
If the determination result is NO for step S624, that is: the action of the current NFC card 10 of receiving is not identical with the action of NFC card 10 in being stored in storer 25, then controller 23 sends " action password mistake; please re-enter the action password " information (step S627) to indicator 29, then, action password setting up procedure turns back to step S606, to reset the action password.
If the judged result of step S624 is yes, that is: the action of the current NFC card 10 of receiving is identical with the action of NFC card 10 in being stored in storer 25, then controller 23 sends a requests for identification information message via antenna 21 to NFC card 10, with the identification information (step S630) of request NFC card 10.
The controller 14 of NFC card 10 received requests for identification information message from read write line 20 via antenna 12 after, controller 14 read the identification information (step S633) of NFC card 10 from storer 16.
The controller 14 of NFC card 10 sends an identification information response message (step S636) via antenna 12 to read write line 20, and wherein, this identification information response message comprises the identification information of the NFC card 10 that reads.
The controller 23 of read write line 20 is received identification information response message from NFC card 10 via antenna 21 after, controller 23 sends a password storage resource request message (step S639) via data communication units 28 to server 30, wherein, this password storage resource request message comprises the action of identification information with the NFC card 10 that detects of the NFC card 10 that comprises in this identification information response message.

Then, when the user is holding NFC card 10 near read write line 20, and when read write line 20 detected NFC card 10 and enters its induction range, the controller 23 of read write line 20 was enabled motion detector 27, and sent " please input action password " information (step S703) to indicator 29.
Then, after the information of receiving self-controller 23, indicator 29 shows the information (step S706) of this reception.
When the user is holding the action of NFC card 10 control and display password above motion detector 27, motion detector 27 detects the action of NFC card 10 by the execution action testing process, and controller 23 (step S709) is exported in the action of the NFC card 10 that detects.What here, motion detector 27 was performed is motion detection process shown in Figure 5.
After receiving the action of the NFC card 10 that motion detector 27 sends, the action of the NFC card 10 that controller 23 will receive is stored in (step S712) in the storer 25.
The controller 23 of read write line 20 sends a requests for identification information message via antenna 21 to NFC card 10, with the identification information (step S715) of request NFC card 10.
The controller 14 of NFC card 10 received requests for identification information message from read write line 20 via antenna 12 after, controller 14 read the identification information (step S718) of NFC card 10 from storer 16.
The controller 14 of NFC card 10 sends an identification information response message (step S721) via antenna 12 to read write line 20, and wherein, this identification information response message comprises the identification information of the NFC card 10 that reads.
The controller 23 of read write line 20 is received identification information response message from NFC card 10 via antenna 21 after, controller 23 sends a password authentification request message (step S724) via data communication units 28 to server 30, wherein, this password storage resource request message comprises the action of the NFC card 10 of storing in the identification information of the NFC card 10 that comprises in this identification information response message and the storer 25.
After the controller 33 of server 30 is received password authentification request message from read write line 20 via data communication units 31, controller 33 from password database 35, retrieve with this password authentification request message in the action (step S727) that is associated with storing of the identification information of included NFC card 10.
Then, controller 33 judge NFC card 10 included in this password authentification request message action and should be from password database 35 action that is associated with storing of the identification information with this NFC card 10 of retrieval whether identical (step S730).
If the determination result is NO for step S730, then controller 33 sends the password authentification response message (step S733) of an expression stroke defect to read write line 20 via data communication units 31.
If the judged result of step S7301 is yes, then controller 33 sends a correct password authentification response message (step S736) of expression action via data communication units 31 to read write line 20.
When the controller 23 of read write line 20 receives password authentification response message from server 30 via data communication units 28 after, if the password authentification response message of this reception shows stroke defect, then controller 23 sends " action password mistake; please re-enter the action password " information (step S739) to indicator 29, then, process turns back to step S706.
