Abstract

An electronic digital mechanical intelligent anti-theft lock can prevent intruder using a universal key and the universal mechanical unlocking technology to unlock, which combines the electronic digital technology and the mechanical lock technology, the electronic digital control technology is added on the basis of original mechanical lock technology, an electronic digital system identification signal with high sensitivity is used for monitoring, and an electronic number is used for identifying the key. Because the electronic digital identification system can identify the effective number in the key to be used as an unlocking or alarming signal, when the electronic digital identification system receives the external unlocking interference, the identification system can accurately identify, generate an automatic alarm and make in an locking state, thereby leading the illegal intruder not to enter into a defended area and to play the anti-theft effect.

Description

Electronic digit mechanical intelligence theftproof lock

Affiliated technical field

The utility model relates to a kind of intelligent anti-theft lock, especially a kind of intelligent anti-theft lock that can prevent that the invador from using master key and universal mechanical unlocking technique to open by force,

Background technology

Existing theftproof lock, when when deploying troops on garrison duty, meeting master key or universal mechanical unlocking technique and unblanking by force, can not discern key voluntarily and let alone freely to open, can not produce automatic warning and lock, so can freely enter the cloth defence area, theftproof lock does not play due effect.

Summary of the invention

For preventing that the invador from using master key and universal mechanical unlocking technique to unblank by force, the intelligent anti-theft lock that the utility model provides a kind of electronic digital technique and mechanical lock technology to combine, this intelligent anti-theft lock combines electronic digit recognition technology and mechanical technique, when when deploying troops on garrison duty, meeting master key or universal mechanical unlocking technique, the capital generation is reported to the police automatically and is locked, and illegal invasion person can not freely enter the cloth defence area.

The technical scheme that its technical problem that solves the utility model adopts is: increase a resistance as data in key, in mechanical lock, increase the electronic digit control system for identifying, utilize key to contact with lock core, transmit data signal and make identification parameter, deliver to electronic recognition system after utilizing the contact read head to read parameter, unblank or alarm signal by the parameter that recognition system identification is sent here, when the contact read head reads external master key or universal mechanical unlocking technique when unblanking, electronic recognition system can both be discerned, and the while sends warning automatically and makes and locking.

The beneficial effects of the utility model are, when meeting illegal invasion person unblanking with master key or universal mechanical unlocking technique when deploying troops on garrison duty, can send automatically and report to the police and make and locking, and illegal invasion person can not freely enter the cloth defence area.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic diagram that reads of the present utility model.

Fig. 2 is a block diagram of the present utility model.

Fig. 3 is circuit theory diagrams of the present utility model.

Battery component 1 among the figure, powered dispenser 2, alarm 3, electromagnetism synchrolock 4, IC ₁ Comparable chip 5, IC ₂Digit chip 6; A is the contact reading assembly, A ₁Be signal output interface, B is the contact transfer assembly, B ₁Be signal backspace input interface after A reads, C connects the electromagnetic lock end, and D is the rechargable power supplies input interface, and E is a key and parameter-embedded, and I is the main controller in the lock.

The specific embodiment

Among the figure, battery component 1 is a rechargeable battery pack, and being responsible for provides working power to anti-theft controller; Powered dispenser 2 and mechanical lock synchro switch are responsible for open and close master controller power supply, are used for conserver power source; Alarm 3 is used to send police whistle sound; Electromagnetic lock 4 is used for the action locking and opens and closes plant equipment.

In accompanying drawing 3, by R ₄Make the major parameter of identification, transmit output through B, by the A-B contact, output after A reads is through R ₂Divide and be sent to IC ₁(3), (6), IC ₁(3), the numeral of (6) and peripheral R ₁, R ₃The comparison that performs an analysis is by IC ₁(1), (7) output, deliver to IC ₂(1), (2), through IC ₂To IC ₁The numeral of delivering to is carried out thresholding relatively, by IC ₂(4), (11) output signal drive and unblank or report to the police, lock.R ₅Be IC ₂The periphery biasing of operate as normal, R ₆For making Q ₂Effectively operate as normal is made current-limiting protection effect, R ₇For making Q ₁Operate as normal is made current-limiting protection effect, Q ₁For electromagnetic lock drives triode, Q ₂For alarm drives triode.

Analyze, drive system is by contact read head A, send by A after reading the parameter that B sends here, through R ₂Carry out the anti-signal parameter sudden change of dividing potential drop, make IC ₁Be in stable duty.The analysis of signal parameter, comparison are by IC ₁(for example LM339LM358 etc.) finishes chip IC ₁To parameter and the peripheral predefined parameter R that is sent here ₁, R ₃Analyze, compare.IC ₂(for example CD4011, CD4081 etc.) is that thresholding is integrated, when only obtaining thresholding numeral working value, and IC ₂(4) just export the control signal that high level is made Q1, otherwise, IC ₂(11) the output high level is made Q ₂Control signal.

Claims

1. an electronic digit mechanical intelligence theftproof lock is characterized in that: increase a resistance as data in key, increase the electronic digit control system for identifying in mechanical lock.
