The electronic lock that a kind of NFC mobile phone compatible electronic password unlocks
This utility model relates to electronic lock field, particularly to the electronic lock that a kind of handset compatibility electronic cipher unlocks.
NFC technique, developed by Non-contact radio-frequency identification (RFID), jointly developed by Philips Semiconductors (Xian Enzhi Pu semiconductor company), Nokia and Sony, its basis is RFID connection technology, and RFID, contactless card reader and point-to-point communication are incorporated into a chip. Near-field communication (NearFieldCommunicationNFC) is the radiotechnics of a kind of short distance high frequency, runs in 20cm distance in 13.56MHZ frequency, and its transmission speed has 106kbit/ second, 212kbit/ second, 424kbit/ second three kinds. ISO/IECIS18092 international standard, ECUA-340 standard and ETS1TS102190 standard is become along with NFC has passed through.
Along with popularizing of mobile Internet, mobile phone is as the most direct intelligent terminal in the Internet, and NFC will be adopted by increasing producer as mobile phone standard configuration. Therefore, NFC technique is more wide in the application prospect in electronic lock field. Can realizing enabling record queries, transmission " analog card " for enabling etc., these are all that RFID door lock is inconvenient or irrealizable function, and it is a kind of technology innovation and development that NFC replaces RFID.
At present, having single NFC mobile phone to open the product of electronic lock, know-why, for utilizing NFC device non-contact card to read its id number, opens electronic lock. But it has the disadvantage that:
1. convenience is not enough: when NFC mobile phone is lost or damages, it is impossible to open electronic lock, can not nullify rapidly nfc card.
2. use and there is limitation: can only opening electronic lock by NFC mobile phone, non-NFC mobile phone can not open electronic lock. Multiple kinsfolks must use NFC mobile phone simultaneously, and guest uses non-NFC mobile phone, and owner cannot remotely send " disposable analog card ", opens electronic lock.
Adopt the electronic lock that NFC mobile phone compatible electronic password unlocks, even if owner's NFC mobile phone is lost, it is also possible to open electronic lock with electronic cipher, nullify nfc card in time.Owner remotely sends not only by NFC mobile phone for " the disposable analog card key " opened the door temporarily to NFC mobile phone user, " disposable enabling electronic cipher " can also be sent to the people of non-usage NFC mobile phone as use of opening the door temporarily, use crowd more extensive. The electronic lock of a kind of NFC mobile phone compatible electronic password that this utility model is invented is compared with single NFC mobile phone electronic lock, convenient, safer, more practical, relatively reliable.
Utility model content
The electronic lock that a kind of NFC mobile phone compatible electronic password unlocks, it is characterized in that: described electronic lock be controlled equipment by NFC and electronic cipher, system that lockset mechanical parts, NFC mobile phone APP application software three part are constituted, NFC mobile phone and NFC and electronic cipher control equipment communication or touch human-computer interface module key entry electronic cipher, NFC module drive motor module forward or reverse, makes lockset mechanical parts open or locking;
Described NFC mobile phone compatible electronic password unlocks, and refers to that this electronic lock has NFC mobile phone and two kinds of system enabling keys of electronic cipher.
The electronic lock that a kind of NFC mobile phone compatible electronic password that this utility model is invented unlocks, has three kinds of electronic open-door modes: nfc card pattern; Electronic cipher; Nfc card pattern+electronic cipher. When NFC mobile phone is lost and damages or do not have the user of NFC functional mobile phone, it is possible to by electronic cipher, open electronic lock and nullify rapidly the nfc card of lost mobile phone. More the more important is in that, NFC mobile phone, it is possible to send the electronic cipher with certain authority to the guest without NFC functional mobile phone, as " disposable enabling electronic cipher " is used for opening the door, it is possible to create safer enabling pattern: NFC mobile phone+electronic cipher.
The electronic lock that a kind of NFC mobile phone compatible electronic password that this utility model is invented unlocks, is constituted by following three:
1.NFC and electronic cipher control equipment
2. lockset mechanical parts
3.NFC mobile phone A PP application software
Mentality of designing:
The electronic lock of a kind of NFC mobile phone compatible electronic password that this utility model is invented, devises two kinds of electronics open modes: NFC mobile phone and electronic cipher. Based on NFC chip, power module, Anneta module forming NFC main equipment, NFC mobile phone is NFC target device, when NFC mobile phone communicates with NFC main equipment, NFC main equipment sends driving instruction to motor module, and control, drive motor just or reverse, and makes lock core be in unlatching or locking states. Applied by APP, NFC mobile phone can read the information such as enabling record of NFC main equipment near field, and carries out point-to-point communication between NFC mobile phone, sends " disposable analog card " and is used for unblanking, other target NFC mobile phone also can be authorized by NFC mobile phone, and the use authority of electronic lock is managed.
In like manner, by touching man machine interface or NFC mobile phone keyboard, door-opening password is inputted. Cipher instruction is processed and judges by NFC chip, sends instruction to motor module, is turned on and off electronic lock.
NFC mobile phone and electronic cipher two kinds open electronic lock pattern, when NFC mobile phone is lost or under damaged condition, can open electronic lock by electronic cipher, and nullify nfc card in time. Also can be used for opening electronic lock to non-NFC mobile phone people's pocket transmission " disposable enabling electronic cipher ". Make electronic lock more conveniently, safely, practical.
Accompanying drawing illustrates: Fig. 1 is the electronic lock schematic diagram that a kind of NFC mobile phone compatible electronic password unlocks
As it is shown in figure 1, the electronic door lock system structure that this utility model is invented, NFC and electronic cipher control equipment, lockset mechanical parts, NFC mobile phone APP application software three part are constituted.By NFC module, power module, Anneta module, touch human-computer interface module, motor module composition lockset NFC and electronic cipher control equipment, and NFC mobile phone and electronic cipher are system enabling key. When the NFC device in NFC mobile phone controls equipment near NFC and electronic cipher and is in communication with or keys in electronic cipher by touching man machine interface, after control equipment confirms and judges its access rights, NFC module sends driving instruction to motor module, drive motor forward and backward, lock core office in motor driven latch tool mechanical parts is in the state of unlatching or locking, it is achieved the open and close of electronic lock.
