Description

A kind of novel intelligent bluetooth lock

Technical field

The utility model relates to smart lock technical fields, and in particular to a kind of novel intelligent bluetooth lock.

Background technique

Mechanical lock traditional at present all only has mechanical unlocking function, and anti-technology unlatching ability is lower, and mechanical key ratio It is easier to replicate, especially can have larger hidden danger when user loses key, lock core and key can only be replaced, lose at high cost.

Utility model content

In view of the above-mentioned problems, the utility model is intended to provide a kind of novel intelligent bluetooth lock.

To realize that the technical purpose, the embodiment of the utility model be:

A kind of novel intelligent bluetooth lock, including lock core control module, key encryption module, bluetooth receiving module, the lock Core control module includes mechanical lock and digital certificate port, and the key encryption module includes mechanical key and Electronic Coding end Mouthful, it is realized between the lock core control module and key encryption module by digital certificate unlocking mode and mechanical unlocking mode double Lock is reopened, the bluetooth module can carry out associated key addition and deletion by mobile terminal, between control module and key module It is communicated by I2C and carries out Electronic Coding certification.

Preferably, the lock core control module and the digital certificate mode of key encryption intermodule pass through on mechanical lock Encryption chip ATSHA204A generate random number, and by random number by I2C be transferred to the ATSHA204A on mechanical key into It reads back again ciphertext after row encryption, finally ciphertext is transmitted into the ATSHA204A in mechanical lock control module and is authenticated.

Preferably, the bluetooth receiving module can carry out the addition and deletion of key ID by mobile terminal, losing Key ID can be removed when key in time keeps it invalid, passes through addition ID again after the new bitting of producer can be received in new bitting Key is set to come into force.

The utility model function is simple, easy to operate, is unlocked by electric mechanical bilayer, and tradition machinery is compared in safety Lock improves very more, and low cost, can use on some hotels, apartment, family.

Detailed description of the invention

Fig. 1 is the structural block diagram of the utility model；

1 lock core control module in figure, 11 digital certificate ports, 2 key encryption modules, 22 Electronic Coding ports, 3 bluetooths connect By module, 4 motor drivens.

Specific embodiment

With reference to the accompanying drawing 1 and specific embodiment the utility model is described in further details.

A kind of novel intelligent bluetooth lock, including lock core control module 1, key encryption module 2 and bluetooth receiving module 3, The lock core control module 1 include mechanical lock and digital certificate port 11, the key encryption module 2 include mechanical key and Electronic Coding port 22 passes through digital certificate unlocking mode and machinery between the lock core control module 1 and key encryption module 2 Unlocking mode realizes dual unlocking, and 4 drawing-in motions are driven by motor in mechanical unlock.

The digital certificate port 11 is made of main control chip nRF51802 and encryption chip ATSHA204A, the electronics Encryption port 22 is encryption chip ATSHA204A, when key is inserted into mechanical lock, controls mould by triggering lock core in mechanical structure Block 1 carries out mechanical key electronic certification, and the lock core control module 1 can read the ID number in key encryption module 2 and itself save Key ID compare, meet ID identification after start to carry out encryption certification.Encryption chip meeting in the lock core control module 1 One group of random code is generated, this group of random code is issued the encryption chip in key encryption module 2 and carried out by main control chip nRF51802 It encrypts and returns to ciphertext.Main control chip verifies the encryption chip that ciphertext is dealt into lock core control module 1 after receiving ciphertext, Realize that electronics is unlocked after being verified, after electronics is unlocked successfully, key can just carry out the mechanical unlocking of motor driven 4 to complete At the process of unlocking.

The bluetooth receiving module 3 is controlled by main control chip nRF51802, and bluetooth receiving module 3 passes through BLE using mobile phone Key ID is added or deleted toward the transmission of lock core control module 1, each encryption chip ATSHA204A has a unique ID number, benefit The identification of key is carried out with this ID number.When new bitting, user passes through mobile phone for key encryption module 2 after taking key Corresponding ID number is sent to lock core control module 1 and is saved, and allows lock core control module 1 that can identify the key of corresponding ID.When When key loss, user can be deleted the correspondence key ID saved on mobile phone by mobile phone, thus make to lose key failure, To guarantee the safety of lock.

The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, all according to this The technical spirit of utility model any trickle amendment, equivalent replacement and improvement to the above embodiments should be included in this Within the protection scope of utility model technical solution.

Claims

1. a kind of novel intelligent bluetooth lock, including lock core control module, key encryption module, bluetooth receiving module, feature exist In: the lock core control module include mechanical lock and digital certificate port, the key encryption module include mechanical key and Electronic Coding port passes through digital certificate unlocking mode and mechanical unlocking between the lock core control module and key encryption module Mode realizes dual unlocking, and the bluetooth receiving module can carry out associated key addition and deletion by mobile terminal, control mould It is communicated between block and key module by I2C and carries out Electronic Coding certification.

2. a kind of novel intelligent bluetooth lock according to claim 1, it is characterised in that: the lock core control module and key Digital certificate unlocking mode between encrypting module is to generate random number by the encryption chip on mechanical lock, and random number is led to Ciphertext of reading back again is crossed after the encryption chip that I2C is transferred on mechanical key is encrypted, finally transmits ciphertext into mechanical lock On encryption chip authenticated.

3. a kind of novel intelligent bluetooth lock according to claim 1, it is characterised in that: the bluetooth receiving module can pass through Mobile terminal carries out the addition and deletion of key ID, and can remove key ID in time when losing key keeps it invalid, is newly matching key Key is set to come into force by adding ID again after producer's new bitting can be received when spoon.
