B, by the information that is sent among the unlocking system determining step A in the NFC portable terminal whether with unlocking system in information be complementary;
C, if the information in result and the unlocking system among the step B does not match, then door lock and does not react;
D, if the interior information matches of result and the unlocking system among the step B is then sent enabling signal by the electronic switch control system of NFC portable terminal in unlocking system;
E, the enabling signal control electromagnetism lockset that is sent by electronic switch control system among the step D are realized unblanking.
As further improvement in the technical proposal, the security information in the above-mentioned steps 1 is fingerprint recognition information or encrypted message or face recognition information or voice messaging.
As further improvement in the technical proposal, the security information in the above-mentioned steps 1 is a fingerprint recognition information, encrypted message, any combination of face recognition information and voice recognition information.
Implement door lock control system and the method thereof based on NFC of the present invention, have following beneficial effect:
Be directed to above situation, the present invention uses the NFC technology, the door lock control system that provides based on NFC, password or finger print information are put into my NFC mobile phone terminal in advance, the door-locking system that constitutes by NFC terminal and intelligent lock system carries out door interlock switch control then, both be convenient to daily life, and safety is also higher.
Description of drawings
Fig. 1 is a system block diagram of writing the information of opening the door of crossing the threshold of the present invention;
Fig. 2 is the flow chart of unblanking of the present invention;
Fig. 3 is the NFC portable terminal control circuit figure that unblanks in the invention.
The specific embodiment
Door lock control method based on NFC provided by the invention may further comprise the steps:
Whether the NFC mobile phone terminal in step 4, the described step 2 is opened with control NFC portable terminal by the point-to-point unlocking system that will the information of unblanking sends NFC portable terminal in the step 3 to.
The process of unblanking in the above step 4 specifically may further comprise the steps:
A, the information of unblanking of NFC mobile phone terminal is sent to the NFC portable terminal;
B, by the information that is sent in the unlocking system determining step 1 in the NFC portable terminal whether with unlocking system in information be complementary;
C, if the information in result and the unlocking system among the step B does not match, then door lock and does not react;
D, if the interior information matches of result and the unlocking system among the step B is then sent enabling signal by the electronic switch control system of NFC portable terminal in unlocking system;
E, the enabling signal control electromagnetism lockset that is sent by electronic switch control system among the step D are realized unblanking.
For said system and method are further described, see also shown in Figure 1ly, implement the door lock control system based on NFC provided by the invention, at first be that the information of opening the door is stored or write; If what the user used is that the mode that numerical ciphers mates is unblanked, as long as simply designed numerical ciphers is deposited in the NFC mobile phone terminal, and encrypted message by the point-to-point NFC portable terminal that is sent to of NFC, and the design of after NFC mobile terminal design coupling, unblanking, thereby finished the information setting of unblanking; If but the user wants to use the mode of finger-print cipher coupling to unblank, the user needs purchase fingerprint reader voluntarily, read finger print information and deposit computer in, by the USB connection finger print information is deposited in mobile phone with the NFC mobile phone terminal, finger print information by the point-to-point NFC portable terminal that is sent to of NFC, and the design of after NFC mobile terminal design coupling, unblanking, thereby finished the information setting of unblanking.Security information in this system can also comprise face recognition information or voice messaging; Also can be the fingerprint identifying information, encrypted message, any combination of face recognition information and voice recognition information.
Referring to shown in Figure 3, the NFC portable terminal control circuit of unblanking comprises two metal-oxide-semiconductors; The resistance R 1 that is connected with the input of two metal-oxide-semiconductors; The utmost point pipe Q1 that is connected with the output of two metal-oxide-semiconductors, the relay U1 that is connected with triode Q1, the electromagnetism lockset J1 that is connected with the output of relay U1 is with relay U1 diode connected in parallel D1; And be the power supply E of two metal-oxide-semiconductors and relay U1 power supply.Wherein U315 is used for detecting the level arrival of whether unblanking, and Q1 is for detecting the on-off circuit of unlocking signal; NFC_CTL is a NFC portable terminal unlocking signal, when NFC_CTL is high level, and conducting U315, and to the input B of Q1 pin, input high level makes the Q1 conducting then, makes the C pin of Q1 also export high level, make electric current flow into 1 pin of relay at last, flow out from 3 pin, thereby start relay switch, make 2 pin of relay and 1 pin carry out conducting, thereby start the electromagnetism lockset, realize unblanking.
Referring to Fig. 2 and shown in Figure 3, when the NFC mobile phone terminal when the NFC portable terminal door control system, and send encrypted message to NFC portable terminal door control system by the NFC mobile phone terminal, differentiate whether correctly coupling of encrypted message by the NFC portable terminal then, when encrypted message is consistent with the password in having the NFC portable terminal, send the information of opening the door by the NFC portable terminal to the control circuit of unblanking, promptly send high level number to circuit, the actuating switch circuit U 315 then, Q1, and starting relay, thereby make the electromagnetism lockset that door is opened, otherwise if encrypted message is when existing password in the NFC portable terminal inconsistent, door lock does not react.
Above embodiment only is that invention is described, yet the present invention is not limited thereto.For those skilled in the art, also be considered as protection scope of the present invention in the various improvement that do not break away from outside the inventive concept scope.
