Abstract
The utility model relates to a magnetically controlled electronic burglar-proof lock, comprising a digital keyboard, a magnetically controlled lock, a computer crypto chip, an alarm and a current magnifier; the gating lines of the digital keyboard are connected to the input end of the computer crypto chip, the output of one path of the computer crypto chip is connected with the magnetically controlled lock by the current magnifier, while the output of the other path is connected with the alarm. A lock code is input to the burglar-proof lock of the utility model by the digital keyboard, the available encoding quantity is large, the deciphering possibility of strangers is quite low, and an audible alarm can be sent out when a wrong password is input, thus greatly enhancing the burglar-proof performance. The magnetically controlled electronic burglar-proof lock is suitable for being installed on various room doors or car doors, and can be used as burglar-proof tools of rickshaws or motor vehicles.
Description
Technical field
The utility model relates to a kind of electronic lock, specifically a kind of magnetic control electronic safety lock.
Background technology
Commercially available lock can be divided into tongue lock and disk type coded lock two big classes substantially at present.The mutual opening rate height of tongue lock, theftproof performance is relatively poor; The coding figure place of disk type coded lock is few, and the chance of giving away secrets is many, and because the relation of internal construction, and the impact sound of the interior metal disc that brings according to turning handle can break a code and unblank.
The utility model content
The purpose of this utility model just provides a kind of multidigit coding, be difficult for the magnetic control electronic safety lock decoded, improving the theftproof performance of lock, for the common people's stable life provides safeguard.
The utility model is achieved in that a kind of magnetic control anti-theft electronic lock, include digital code keyboard, magnetic control lock, computer cipher chip, alarm and current amplifier, the select lines of digital code keyboard is connected to the input of computer cipher chip, one tunnel output of computer cipher chip connects magnetic control lock through current amplifier, and device taking alarm is exported on another road.
The used computer cipher chip of the utility model can be accepted the password of the 1-12 position of institute's subsection according to the setting up on their own of user.After the user was by the correct password of digital code keyboard input, the computer cipher chip was the exportable pulse of unblanking.This unblanks pulse after current amplifier amplifies, and drives the electromagnetic valve action in the magnetic control lock, and lock is opened.If the password bad of input then can not drive magnetic control lock and unblank.Behind three (can set) bad passwords of input, the computer cipher chip is exported starting impulse to alarm, and (can set) warns to make alarm send alarm sound one minute, to draw back theft with fear.The coding of 1-12 position has 1,000,000,000 more than, and the probability that the stranger decodes is almost nil, therefore the theftproof performance of this lock is improved greatly.
The utility model is suitable for being installed on various doors or the car door, also can be used as the antitheft apparatus of rickshaw or electric motor car.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
The specific embodiment
As shown in Figure 1, this magnetic control anti-theft electronic lock includes digital code keyboard 1, magnetic control lock 2, computer cipher chip IC
1, alarm 3 and current amplifier.Digital code keyboard 1 can be selected 12 telephone keypads of standard for use, wherein except that ten figure keys of 0-9, also has " M " memory button and " K " unlock key." M " memory button is used for setting or changing password, and " K " key is the button that is used to unblank after the password input.Magnetic control lock 2 can be selected existing approved product for use.The computer cipher chip IC
1Can select SR301 for use, its 5-8 pin and the 10th to 11 pin are input, connect the ranks select lines of digital code keyboard 1; Its 15th and 17 pin is two outputs.The 17th pin output termination current amplifier.Current amplifier is by compound transistor T
1, T
2With base resistance R
1Connect to form (also can adopt other amplifier architectures certainly), triode T
2Colelctor electrode as on the electromagnetic valve in the output termination magnetic control lock 2 of current amplifier.The computer cipher chip IC
1The 15th pin output device 3 taking alarm.Alarm 3 can be selected the KD9561 alarm chip for use, is connected to resistance R at the input of this alarm chip
2, at the output of alarm chip through capacitor C
4Connect loudspeaker Y.Certainly, also can select for use other alarm chips to form alarm.
Be to guarantee the utility model reliably working, can adopt the power supply mode of multiple power supplies, in these three kinds of modes of promptly available AC power, dc source and outer input jack two kinds or whole.
