Description
Technical field
The utility model relates to smart card application technologies field, particularly with the passive smart lock of mobile phone NFC communication.
Background technology
NFC is that Near Field Communication abridges, i.e. near field communication (NFC).NFC mobile phone refers to the mobile phone with NFC module.NFC has Three models: mode card, card reader pattern and point-to-point type.Mode card is exactly the equipment simulating with NFC function is become a non-contact card, as access card, bank card etc.Namely card reader pattern uses as contactless card reader.Point-to-point type is about to the linking of devices that two possess NFC function, realizes Point-to-Point Data Transmission.
In prior art, smart card induction lock is widely used in the occasion such as hotel, bathing.There is contactless card reader smart card induction lock inside.When user takes non-contact card to unblank, contactless card reader reads non-contact card identification user identity.When smart card induction lock determination user identity, its internal drive actuator is unblanked.Whether smart card induction lock active period detects has non-contact card to close on, and needs to continue to provide electric energy to it.Just need after dead battery capability to change battery.Generally every just needs more than a year changes one-shot battery, and it is convenient not to use.
Summary of the invention
Needing often to change the shortcoming of battery in order to solve smart card induction lock continued power in above-mentioned prior art, the utility model proposes a kind of passive smart lock for communicating with NFC function card reader mode handset.It, without the need to using Power supply, reduces manufacturing cost and use cost simultaneously.
In order to reach foregoing invention object, the technical solution of the utility model realizes as follows:
The passive smart lock communicated with NFC function card reader mode handset, its design feature is, it is made up of antenna, control module, large value capacitor and actuator.Control module is the module or the chip that comprise noncontact passage, power supervisor, micro-control unit, coulometric detector and driving circuit.The noncontact passage of antenna and control module is interconnected, and control module obtains electric energy and contactless communication from antenna.Power supervisor from noncontact passage obtain electricity and and large value capacitor be interconnected.Noncontact passage and micro-control unit are interconnected.Micro-control unit is connected to actuator through driving circuit, and large value capacitor is connected to micro-control unit through coulometric detector.
The utility model is owing to have employed said structure, and smart lock, without the need to using Power supply, reduces the manufacturing cost and use cost of lockset simultaneously, suitable widespread use.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is used for being made up of antenna 1, control module 2, large value capacitor 3 and actuator 4 with the passive smart lock communicated with NFC function card reader mode handset.Control module 2 is for comprising module or the chip of noncontact passage 2.1, power supervisor 2.2, micro-control unit 2.3, coulometric detector 2.5 and driving circuit 2.4.Antenna 1 is interconnected with the noncontact passage 2.1 of control module 2, and control module 2 obtains electric energy and contactless communication from antenna 1.Power supervisor 2.2 from noncontact passage 2.1 obtain electricity and and large value capacitor 3 be interconnected, noncontact passage 2.1 and micro-control unit 2.3 are interconnected.Micro-control unit 2.3 is connected to actuator 4 through driving circuit 2.4, and large value capacitor 3 is connected to micro-control unit 2.3 through coulometric detector 2.5.
The method step that the utility model passive smart lock realizes unblanking is as follows:
1) NFC mobile phone closes on the antenna 1. of passive smart lock as card reader Mode Launch carrier wave
2) power supervisor 2.2 of control module 2 obtains electricity by noncontact passage 2.1, and this electricity is used for the operation of control module 2 and charges to large value capacitor 3.
3) step 2) while, NFC mobile phone is communicated with micro-control unit 2.3 with the noncontact passage 2.1 of control module 2 by antenna 1, and after having communicated, the micro-control unit 2.3 of control module 2 identifies that whether NFC mobile phone identity is legal.
4) step 2) while, the micro-control unit 2.3 of control module 2 carries out electric power detection by coulometric detector 2.5 pairs of large value capacitors 3, judges that whether the electricity of large value capacitor 3 is up to standard.
5), when step 3) and step 4) satisfy condition simultaneously, the micro-control unit 2.3 of control module 2 controls driving circuit 2.4 actuate actuators 4 and unblanks, otherwise does not unblank.
By a kind of embodiment, the utility model is illustrated above, but the utility model is not limited thereto.In addition, user can use NFC mobile phone, opens the APP that unblanks, and after inputting password or fingerprint authentication, passive smart lock is closed in mobile phone card-brushing region.Passive smart lock antenna 1 obtains the carrier energy of NFC mobile phone, and its control module 2 charges and detect charge capacity in real time to large value capacitor 3.Meanwhile, NFC mobile phone communicates with passive smart lock control module 2, and NFC mobile phone identity obtains passive smart lock accreditation.Now, when large value capacitor 3 electricity enough drives the actuator 4 of passive smart lock, control module 2 controls the execution of large value capacitor 3 energy drives actuator 4 and unblanks.Otherwise, do not perform and unblank.
The utility model passive smart lock realizes in the whole process of unblanking, and the mobile phone with NFC function is card reader pattern, and passive smart lock is the smart lock with non-contact card function.These are different from traditional smart card induction lock.
