Description

Electric lockset pick-proof protection circuit
Technical field
The present invention relates to a kind of electric lockset, more particularly to a kind of electric lockset pick-proof protection circuit.
Background technology
Lockset is born to be continuous has thousands of years of history so far, is popularized with the development of electronic information technology, and society is right The raising of demand for security, lockset have developed into new electric lockset by traditional mechanical lock.Electric lockset overcomes tradition The shortcomings that mechanical lock number of password is few, and a variety of unlocking modes such as password unlocking, fingerprint unlocking, chip card unlocking have been merged, Greatly improved in terms of security and applicability compared with tradition machinery lockset.
Check is compared by internal processor chips, split lock information in electric lockset, and unlocking information is correct Unlocking electric signal is sent, driving (motor, electromagnet etc.) is unlocked, and unlocking after all is one by processor chips Individual unlocking drive signal is realized.
The lock body of usual electric lockset is made up of outdoor, indoor two parts, is easy to installing and using for circuit design and lockset, Wherein outdoor section is integrated with unlocking unit (password, fingerprint, swiping the card), and indoor section is integrated with power supply, specific function Button (system password initialization, system reset etc.), it is contemplated that outdoor reliable with the terminal strip number and circuit of indoor lock body Property, the main control board with processor chips, which is commonly designed, to be placed in outdoor lock body, with the wiring for the unit that shortens and unlock Distance, reach the purpose of enhancing circuit reliability；Reduce outdoor and indoor lock body terminal strip number simultaneously, be easy to lockset peace Dress.But this design causes a kind of hidden danger, unlock and initializing signal is excessively simple, only low and high level is distinguished, and is not compiled Code encryption.If outdoor lock body destroyed, unlocking drive signal line or special key signal wire therein are found, outside applies High/low level signal, you can motor, electromagnet etc. are unlocked or cause lockset cryptographic initialization, so that lockset is beaten Open.
The content of the invention
, can not influenceing circuit the invention provides a kind of electric lockset pick-proof protection circuit in order to overcome drawbacks described above On the premise of installing and using by property and lockset, solve to destroy the technical problem that outer lock body utilizes signal wire external signal to unlock.
The present invention in order to solve its technical problem used by technical scheme be：A kind of electric lockset pick-proof protection circuit, Including outdoor lock body and indoor lock body, the outdoor lock body has primary processor and the unlocking list of letter connection is passed with the primary processor Member, the indoor lock body include passing the special function keys of letter connection, the unlocking for driving lockset to open with the primary processor Element and the power supply that electricity is provided for all parts, secondary processor are additionally provided with the indoor lock body, the secondary processor Communicated with the primary processor by coding encrypting, and with the unlocking element and special function keys respectively by high/low Level signal passes letter connection；After the primary processor receives the unlocking information of unlocking unit, the information is verified, tested Unlocking signal is encoded and is sent to the secondary processor by card after passing through, and the secondary processor is opened by the control of high/low level signal Locking element works.
As a further improvement on the present invention, the unlocking unit comprises at least password unit, fingerprint input part and brush One of card input block.
As a further improvement on the present invention, the unlocking element is motor or electromagnet.
As a further improvement on the present invention, the power supply provides working power for the secondary processor simultaneously.
As a further improvement on the present invention, the special function keys include system password initialization button and system is answered Position button.
The beneficial effects of the invention are as follows：The electric lockset pick-proof protection circuit by the secondary processor on indoor lock body with Primary processor on outdoor lock body establishes coding encrypting communication, and checking of unlocking still is completed by primary processor, when main process task is receiving To after unlocking information (password, fingerprint, swiping the card), the information is verified, is verified to encode unlocking signal and sends out Secondary processor is given, control secondary processor is unlocked.Secondary processor receives indoor special function keys, and (such as system is close Code initialization, system reset etc.) after, the Signal coding is sent to primary processor, primary processor receives the coding, after decoding Perform cryptographic initialization or system reset associative operation, you can after avoiding outdoor lock body destroyed, by finding driving letter of unlocking Number line or special function keys signal wire, are subject to the problem of simple Automatic level control can unlock or initialize, are not influenceing circuit Under the precondition that reliability and lockset are installed and used, the security of lockset is improved.
Brief description of the drawings
Fig. 1 is circuit theory diagrams of the present invention.
With reference to accompanying drawing, make the following instructions：
1 --- outdoor lock body 2 --- indoor lock body
10 --- primary processor 11 --- password units
12 --- fingerprint input part 13 --- input blocks of swiping the card
21 --- special function keys 22 --- unlocking elements
23 --- power supply 24 --- secondary processors
Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment to the present invention elaborates.But protection scope of the present invention is not It is limited to following embodiments, i.e., the simple equivalence changes made in every case with scope of the present invention patent and description are with repairing Decorations, all still belong within patent covering scope of the present invention.
It is a kind of electric lockset pick-proof protection circuit of the present invention refering to Fig. 1, including outdoor lock body 1 and indoor lock Body 2, the outdoor lock body have primary processor 10 and with the primary processor pass letter connection unlocking unit, the indoor lock body include with The primary processor passes the special function keys 21 of letter connection, the unlocking element 22 for driving lockset unlatching and is each portion Part provides the power supply 23 of electricity, and secondary processor 24 is additionally provided with the indoor lock body, the secondary processor and the main process task Device is communicated by coding encrypting, and is passed and believed by high/low level signal respectively with the unlocking element and special function keys Connection；After the primary processor receives the unlocking information of unlocking unit, the information is verified, will be opened after being verified Lock signal coding is sent to the secondary processor, and the secondary processor controls unlocking element manipulation by high/low level signal.
Wherein, the unlocking unit comprise at least password unit 11, fingerprint input part 12 and swipe the card input block 13 its One of, the unlocking element is motor or electromagnet, and the power supply provides working power for the secondary processor simultaneously, institute Stating special function keys includes system password initialization button and system reset button.
