As shown in Figure 4, what the present embodiment provided a kind of electronic lock realizes system, and the course of work can comprise:
App is downloaded in 41:NFC mobile terminal, application is sent to App background server by App register interface, verify that cell-phone number is that I am in use by identifying code mode, using cell-phone number as electron key ID, background server is sent to my mobile phone through security algorithm determination identifying code, and it has been registration that identifying code acts on herein.
When other NFC mobile terminal except mobile phone are registered, cell-phone number also can be adopted as No. ID, electron key, but identifying code is sent to registration mobile phone.
42: hair fastener authorized device one end USB free drive flowing mode connects the controller management software of electronic lock controller, the NFC chip of hair fastener authorized device reads App store electrons key ID (cell-phone number) in NFC mobile terminal and is directly sent in the controller management software of electronic lock controller by the electron key ID read.
If when using common non-contact inductive card, then what read is the unique ID number of card, using this No. ID electron key ID as card.
43: user carries out electronic lock mandate to electron key ID in the man-machine interaction graphical interfaces of electronic lock controller management software, and ID right to certificate limit information is issued in electronic lock controller.
After 44:NFC mobile terminal opens App, near NFC electronic lock card reader during runnable interface state, NFC chip in NFC electronic lock card reader and the NFC chip of NFC mobile terminal carry out interactive communication, and the electron key ID (cell-phone number) prestored in App and identifying code transfer to NFC chip Signal analysis and the processing module of NFC electronic lock card reader end by radio frequency antenna module.
45:NFC electronic lock card reader poll intercepts radiofrequency signal, identify electron key signal, the master controller of NFC electronic lock card reader carries out security algorithm analysis to the electron key signal transmitted, and whether comparison authorizes the identifying code of generation consistent in the air, after determining non-robber brush lock and legal App, the transmission interface agreement that the master controller of NFC electronic lock card reader is taked according to electronic lock (includes but not limited to Wei root 26, 34, RS232, RS485 etc.) different, by the electron key ID (cell-phone number) obtained, to the process of electron key standardized format, then be sent to electronic lock controller and do authentication.
If use common non-contact inductive card, or when NFC mobile terminal contains hardware safe unit or software cryptography safe unit, then NFC electronic lock reader identification electron key signal obtains electron key ID, (Wei root 26,34 is included but not limited to according to the transmission interface agreement that electronic lock is taked, RS232, RS485 etc.) different, send electron key ID and do authentication to electronic lock controller.
46: electronic lock controller, according to the electron key ID stored and authority information, carries out certification to the electron key ID passed over, determine whether to electric control opening device send out blocking order.
47: the automatically controlled opening/closing locking device of electronic lock according to the electronic lock controller received send open blocking order perform unblank or do not do unlocking action.
The system that realizes of the present embodiment NFC electronic lock and NFC electronic lock card reader, compatible conventional contactless contactless card, user is without in NFC mobile phone situation, legacy card or NFC label mode can be used to open electronic lock, extend use value and the usable range of system greatly, meanwhile, also for the upgrading of original system is provided convenience, cut the waste and duplicate construction.
The system that realizes of the present embodiment NFC electronic lock and NFC electronic lock card reader, according to current technical development situation and future technical advances situation, according to NFC chip inherent characteristic, take P2P mode of operation and snap gauge simulation models to carry out double mode electronic lock lock of opening to design, make system have larger extendability and dirigibility future, also can play the effect cut the waste with duplicate construction.
Cell-phone number under safety verification code is assisted is as No. ID, electronic lock electron key, hommization angle considers convenience and the understanding of user, also provide enhanced the attendance checking function of electronic lock, the intrinsic not reproducible characteristic of cell-phone number substituted for the uniqueness of electronic lock under biological identification technology, reduce Subscriber Unit use cost and use difficulty, also fundamentally stop Subscriber Unit gathers employee information and accidental release illegal act without authority of law, strengthen Socialist law construction and the ruling by law idea improving people.
