Description

Authentication lockset

Technical field

The utility model relates to a kind of intelligent and safe lockset more particularly to a kind of authentication locksets.

Background technique

Traditional lockset is to be opened using corresponding key, but this mechanical key is very easy to copy, therefore pass There is very big loophole in safety in the lockset of system.And some electronic access control systems are opened using digital certificate card or password It opens, has very big improvement in safety, but this electro-magnetic door is once powered off and will be turned on, and this dependence It still is able to pull open if magnetic force encounters stronger pulling force the structure locked a door, therefore there is also very big security risks.

Summary of the invention

The purpose of this utility model：A kind of authentication lockset by that could open after authentication is provided.

To achieve the goals above, the technical solution of the utility model is：

A kind of authentication lockset, including rotation blocker, rotation driving circuit, controller for authentication, authentication code drive mould Block, overtime ReSet Circuit and power supply, the rotation blocker are connected to rotation driving circuit, the controller for authentication difference It is connected to rotation driving circuit, authentication code drive module, overtime ReSet Circuit and power supply.

Above-mentioned authentication lockset, wherein the rotation driving circuit uses direction and moves drive module TMC2130-LA。

Above-mentioned authentication lockset, wherein the controller for authentication uses safety certification and controls microprocessor HD64F36079GHV。

Above-mentioned authentication lockset, wherein the authentication code drive module uses NFC authentication code identification chip PN5180。

Lockset key is configured and authenticates RF tag by the utility model, and is also matched inside corresponding lock controller Authentication code information is set, only by the key of authentication, lockset understands unlocking key hole just in order to which key can successfully be held Open the lockset.The utility model can be improved the safety of lockset, eliminate conditional electronic lock by increasing authentication to key With the security risk of access control system.

Detailed description of the invention

Fig. 1 is the internal structure chart of the utility model authentication lockset.

Fig. 2 is the functional block diagram of the utility model authentication lockset.

Specific embodiment

The embodiments of the present invention that the following is further explained with reference to the attached drawings.

Referring to Figure 1 and shown in Fig. 2, a kind of authentication lockset, including rotate blocker 1, rotation driving circuit 2, recognize Controller 3, authentication code drive module 4, overtime ReSet Circuit 5 and power supply 6, the rotation blocker 1 is demonstrate,proved to be connected to rotation and drive Dynamic circuit 2, the controller for authentication 3 are connected respectively to rotation driving circuit 2, authentication code drive module 4, overtime ReSet Circuit 5 and power supply 6.

The electronic label code of the corresponding certification RF tag of 3 storage inside of controller for authentication, while certification is penetrated Frequency marking label are mounted on corresponding lockset on the key, when the key close contact configured with certification RF tag is to lockset, recognize Card controller 3 can control the electronic tag for the certification RF tag that authentication code drive module 4 is read on the key by SPI interface Code, and electronic label code is transferred on controller for authentication 3, controller for authentication 3 passes through the electronic label code that will be acquired and inside All electronic label codes of storage are compared one by one, consistent if there is comparing, and represent current key as the key by certification Spoon, then controller for authentication 3 starts driving current by SPI digital interface control rotation driving circuit 2 to drive rotation to block Device 1 rotates, so that keyhole is blocked opening, the key which passes through smoothly can open lockset by keyhole, Authenticated by above-mentioned key, so as to effectively prevent other staff's unauthorized privately caused by copy key it is dangerous Property.When key is by certification, the controller for authentication 3 drives rotation blocker 1 to open by control rotation driving circuit 2 Clocked operation is carried out to overtime ReSet Circuit 5 after the blocking of keyhole, can be started immediately, overtime ReSet Circuit 5 uses real-time Clock circuit, when controller for authentication 3 passes through the time-out time that the time that overtime ReSet Circuit 5 is read is more than inner setting, representative Keyhole opens time-out, and whether the key for no matter passing through certification at this time opens lockset, and the controller for authentication 3 can control rotation Turn driving circuit 2 to drive rotation blocker 1 to block closing keyhole, thus the safety of effective protection lockset, to improve lockset Safety.

If controller for authentication 3 is read by authentication code drive module 4 less than electronic label code or the electronics mark of reading Label code and the comparison of all electronic label codes of 3 storage inside of controller for authentication can not pass through, and just represent the key without certification, Therefore it can be blocked by rotation blocker 1 and fail to open lockset.

The rotation driving circuit 2 uses direction and moves drive module TMC2130-LA.

The controller for authentication 3 uses safety certification and controls microprocessor HD64F36079GHV.

The authentication code drive module 4 uses NFC authentication code identification chip PN5180.The authentication code drives mould Block 4 can read the electronic label code of RF tag by radio frequency read-write in certain reading/writing distance.The authentication code Drive module 4 is configured with read-write antenna, can increase the reading/writing distance of radiofrequency signal.

The rotation blocker 1 uses stepper motor and rotates shutter, thus realize to keyhole block and It opens.

The utility model can be improved the safety of lockset, eliminate conditional electronic lock by increasing authentication to key With the security risk of access control system.
