Description

Blue-tooth intelligence safety door latch

[technical field]

This utility model relates to a kind of safety door latch, is specifically related to blue-tooth intelligence safety door latch, belongs to electronic intelligence lockset systems technology field.

[background technology]

Current existing intelligent door lock or gate control system, be used mostly local password, non-contact IC card or NFC technique and realize；In existing technology, the mode of local password cannot realize centralized management, also cannot ensure that password does not leak, thus can bring security risk, is only suitable for using on a small scale；Adopt the door lock of fingerprint identification technology, because cost control problem, the unlocked by fingerprint door lock that open market is sold, it is all optically fingerprint is identified, degree of accuracy is not high, it is possible to by referring to that the plain modes such as mould walk around fingerprint recognition, bring potential safety hazard to door lock；Using the mode of non-contact IC card, be required for providing an IC-card for each user, in use there is loss or stolen situation in IC-card；Management for card neither be accomplished real-time and accurate, there is security risk；Being also required to for a user report the loss make up, these problems are technically difficult to solution；NFC mode can improve the safety of system, but the use of this technology improves user's threshold, and user have to the mobile phone of NFC function or the card allotting support NFC function.

These three mode also has one to common disadvantage is that the disposable enabling mandate that cannot solve temporary visitor, or the owner oneself forgets Password, unblock problem when leaving behind IC-card or nfc card；The safety in safety door latch use procedure and convenience two large problems need to be solved simultaneously, for this, we have proposed blue-tooth intelligence safety door latch.

[utility model content]

The technical problems to be solved in the utility model overcomes existing defect, blue-tooth intelligence safety door latch is provided, it is completely free of conventional door lock or the dependence of gate control system correspondence IC-card or nfc card, Bluetooth mobile terminal completes to arrange by configuring switch initiation door lock, Bluetooth mobile terminal transmits dynamic password by Bluetooth protocol, bluetooth communication module is sent to control unit after receiving, control unit sends the cryptogram to TOTP cryptographic check module and verifies, as verified failed buzzer feedback prompts sound, as verification transmits a signal to driving motor by control unit, door-lock opening；Solve the safety in electronic lock use procedure and convenience two large problems simultaneously.

In order to solve above-mentioned technical problem, this utility model provides following technical scheme:

This utility model provides blue-tooth intelligence safety door latch, grille main body and the fixing buckle of doorframe, described grille main body includes the external numeric keypad in front and the door handle at the back side, the dead bolt of traditional B+level lock core and carrier state inducing function is included inside grille main body, dead bolt is by drive motor, control unit is by configuring whether on-off control enters configurable state, battery compartment is responsible for providing the whole door lock of driven by power, bluetooth communication module is responsible for receiving the password of Bluetooth mobile terminal transmission, control unit is connected with TOTP cryptographic check module and induction apparatus, carry out cryptographic check and door lock state perception, can be inputted by external numeric keypad when without Bluetooth mobile terminal, buzzer can send alarm when door lock exception.

As a kind of optimal technical scheme of the present utility model, under described grille main body duty, Bluetooth mobile terminal completes to arrange by configuring switch initiation door lock, Bluetooth mobile terminal transmits dynamic password by Bluetooth protocol, bluetooth communication module is sent to control unit after receiving, and control unit sends the cryptogram to TOTP cryptographic check module and carries out verification decoding, as verified failed buzzer feedback prompts sound, dead bolt, door-lock opening is regained as verification transmits a signal to driving motor by control unit.

As a kind of optimal technical scheme of the present utility model, whether described control unit can pass through the status checkout door lock of induction apparatus and dead bolt by abnormal opening, as abnormal buzzer high pitch is reported to the police, control unit can monitor the battery dump energy of battery compartment, low electricity early warning is provided, when battery compartment battery is completely depleted or during control circuit fault, can pass through traditional B+level lock core and open the door, for Emergency use.

This utility model reaches to provide the benefit that: is set up by the bluetooth communication module of Bluetooth mobile terminal and door lock and connects, it is possible to allows user realize contactless unblanking, and eliminates the input mode such as password or brush finger stricture of vagina, facilitates user for the use of safety door latch；Do not worry that password is revealed or loses simultaneously, substantially increase the safety in use of electronic lock password；Use bluetooth as communication modes, significantly relax the requirement using scene and equipment, reduce system deployment and implement difficulty, improve Consumer's Experience；The double check of tapered end and door state is provided, runs into fortuitous event, prized such as door or door lock is destroyed, it is possible to send buzzing and report to the police；When the inefficacy of safety door latch electronic installation or running down of battery, it is possible to automatically switch to conventional door lock form, make to turn the key in the lock.
