Abstract
The utility model discloses an IC card computer lock capable of ciphering by a user. In the utility model, an input port of a control board of the existing IC card computer lock is provided with a data dial switch and a state dial switch which is used for the conversion of cipher input state and a working card distributing state; namely, when the computer lock is arranged in a working state, the IC card computer lock has the function of a lock, when the computer lock is arranged in the card distributing state, the IC card computer lock has the function of a card distributing device; moreover, under the control of the software of a micro computer, the ciphering action can be automatically carried out to distribute a new card; the security performance of the IC card computer lock can be improved thereby.
Description
The utility model relates to a kind of micro computer lock, is specially adapted to the gate control system that antitheft door, proof box, confidential cabinet etc. need be established password certainly.
At present, the IC-card door-locking system normally is made up of door lock, IC-card, hair fastener and the computing machine access control system of band micro computer.Because it has higher secrecy than mechanical lock and general electronic lock, thus by the field boundary of centralized management such as hotel, restaurant, intelligent office block adopt.The fatal shortcoming of this IC-card computer lock is that lockset can not be established password certainly.Like this, not only brought inconvenience, and security performance also has been subjected to influence to the user.
In view of the above problems, the purpose of this utility model provides a kind of simple in structure, easy to use, and security performance is good, and can establish the IC-card computer lock of password certainly.
Task of the present utility model is achieved through the following technical solutions:
The utility model is provided with a data toggle switch and a state toggle switch on the input port of the control panel of existing IC-card computer lock, as the conversion of password input and two states of work hair fastener; When the computer lock was arranged on duty, the IC-card computer lockset had the function of lockset; When the computer lock was arranged on the hair fastener state, IC-card computer lock then had the function of card sender, and promptly computer is locked under the control of micro computer software, can establish password certainly, the distribution neocaine.
The IC-card computer lock of forming according to said structure includes parts such as lock housing, lock core and master control borad, with the core of single-chip microcomputer as master control borad, state toggle switch, data toggle switch are as input equipment, IC-card seat, driving circuit, drive motor, sliding-tongue, sound and light alarm element etc. are formed execution unit, a kind ofly have high security energy very, and can establish the IC-card computer lock of password certainly thereby constitute.
Through the lock of the IC-card computer after the above-mentioned design, compact conformation, reasonable, easy to use, security performance is good, is a kind of desirable IC-card computer lockset that can establish password according to user's requirement certainly.
Concrete structure of the present utility model and embodiment be as shown in drawings:
Fig. 1 is a theory diagram of the present utility model
Fig. 2 is the structural representation of the utility model embodiment
Fig. 3 is the electrical schematic diagram of the utility model embodiment
Below in conjunction with accompanying drawing, concrete structure of the present utility model is elaborated:
A kind of IC-card computer lock that can establish password certainly is a kind of damascene structures, and it includes door lock back cover 1, lock core 2, parts such as IC-card computer lock master control borad 3, door lock fore shell 4 and handgrip 6.In lock core 2.Be provided with opening square 10, actuating motor 13, sliding-tongue 14 and lock core movable lug 15, actuating motor 13 is connected with driving lever 12 by worm screw 11, one end of driving lever 12 inserts in the square hole of sliding-tongue 14 afterbodys, constitutes unlatching, the closing organ that the IC-card computer is locked with sliding-tongue 14.IC-card computer lock master control borad 3 is connected with actuating motor 13 by extension line 5,9.By IC-card computer lock master control borad 3, then may command actuating motor 13 is done the rotating campaign, to realize the opening and closing of computer lock.
On the master control borad 3 of IC-card computer lock, be provided with single-chip microcomputer IC1, IC-card seat, Programmable Watchdog E EPROM (X25045) IC2, power supply monitor and driving circuit IC3.On the input end of single-chip microcomputer IC1, be provided with a data toggle switch K1 and a state toggle switch K2, as the conversion of password input and two states of work hair fastener; Data toggle switch K1 and state toggle switch K2 are installed in the inboard of master control borad 3, could be provided with when only opening the door lock back cover.
Data toggle switch K1 receives the P of single-chip microcomputer IC1 through pull-up resistor Rep2
2Mouthful, state toggle switch K2 receives the P of single-chip microcomputer IC1 through pull-up resistor Rep1
3Mouthful; IC-card seat and Programmable Watchdog E EPROM (X25045) IC2 meet the P of single-chip microcomputer IC1
1Mouthful; Driving circuit IC3 meets the P of single-chip microcomputer IC1
0Mouthful, its output control actuating motor M, sound SPK, pilot lamp LED1, LED2, and pass through IC5
-2Come self-insurance.Triode T1, T2 (8550 * 2) make the switch of the power supply of general supply and IC-card seat respectively; Triode T3, T4 (8550 * 2) constitute bridge circuit with IC3 and control actuating motor M, drive sliding-tongue 14 and stretch in the opening part of opening square 10, make the handgrip of lock can rotate-unblank, or static-shut.
After IC-card inserts deck, triode T1 conducting, the activation system power supply, and by IC5 (PC817) self-insurance, single-chip microcomputer IC1 makes triode T2 conducting, the state of detected state toggle switch K2 if state toggle switch K2 is arranged on duty, then carries out legitimacy identification and checks cipher to IC-card, when meeting, starter motor M drives sliding-tongue 14 handgrip rotation one is unblanked, and sound and light alarm.Through a period of time
Work time-delay, and close door lock is promptly cut off the electricity supply the function of finish checks cipher, opening the door lock lockset after pulling out card automatically.During illegal operation, false alarm.
When state toggle switch K2 was the hair fastener state, software was waited for K1 toggle switch input password, under the preceding topic of assert the IC-card legitimacy, revises the password of card, finish from the function of establishing the card sender of password, and acousto-optic is correctly reported to the police.
