Description

Hotel's lock of a kind of Mifare card, both compatibilities of magnetic card

Technical field

The present invention relates to a kind of lockset, particularly the hotel of a kind of Mifare card, both compatibilities of magnetic card lock.

Background technology

Lockset roughly has mechanical lock and electric lockset two large classes, at present, and generally popular dependable performance, the electric lockset that uses safety, conveniently opens; Along with the lot of unstable that occurs in the high speed development of society and the evolution, people also are faced with more safety problem, the safety of aspect, hotel especially, and hotel's safety is with headed by the theftproof performance of door; Lockset is non-anti-theft and economic loss and safety problem that cause still are present urgent problems; Novel intelligent lock is except using mechanical key unblanks on the market, can also directly access to your password or fingerprint is opened lockset, and these bring certain facility can for hotel, office administration; Unblank but access to your password, worry that password penetrated by the people, use fingerprint to unblank, then need fingerprint just can unblank, act as the leader or the supvr need to open lockset fingerprint owner and then do not bother very much at the scene; And the above securely unlocking scheme of taking all can't control by system software, is not with time function, can't follow the trail of at any time the people's that opens the door information, also can't read the record of opening the door.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of novel Mifare card of controlling with system software, hotel's lock of both compatibilities of magnetic card are provided, the anti-theft, the security that have improved lockset are also provided convenience to hotel management simultaneously.

In order to achieve the above object, technical scheme of the present invention is as follows:

Hotel's lock of a kind of Mifare card, both compatibilities of magnetic card is characterized in that: comprise that single-chip microcomputer integrated circuit, Mifare card are known the card circuit, magnetic card is known card circuit, power supply; Circuit system is known the card circuit with the Mifare card respectively by four pin of single-chip microcomputer integrated circuit and is connected, and receives the Mifare card and knows the Mifare card signal that the card circuit sends, and whether system is correctly judged the Mifare card signal that receives; Circuit system is known the card circuit with magnetic card respectively by three pin of single-chip microcomputer integrated circuit and is connected, and receives magnetic card and knows the magnetic card signal that the card circuit sends, and whether system is correctly judged the magnetic card signal that receives.

System is lock core interface and the driving of the side's of comprising tongue, latch bolt, mechanical key composition also; System is sent to the square tongue signal pins of single-chip microcomputer integrated circuit to square tongue signal by square tongue, the latch bolt signal is sent to the latch bolt signal pins of single-chip microcomputer integrated circuit by latch bolt.

The present invention adopts Mifare card and two kinds of unlocking systems of magnetic card, and two schemes all can be unblanked separately, and can follow the trail of at any time the people's that opens the door information, reads the record of opening the door, and has high safety, reliability height, good confidentiality and advantage easy to use.

Embodiment

The present invention is further detailed explanation below in conjunction with drawings and Examples:

Hotel's lock of a kind of Mifare card, both compatibilities of magnetic card is characterized in that: comprise that single-chip microcomputer integrated circuit, Mifare card are known the card circuit, magnetic card is known card circuit, power supply; Circuit system is known the card circuit with the Mifare card respectively by four pin of single-chip microcomputer integrated circuit and is connected, and receives the Mifare card and knows the Mifare card signal that the card circuit sends, and whether system is correctly judged the Mifare card signal that receives; Circuit system is known the card circuit with magnetic card respectively by three pin of single-chip microcomputer integrated circuit and is connected, and receives magnetic card and knows the magnetic card signal that the card circuit sends, and whether system is correctly judged the magnetic card signal that receives; System is lock core interface and the driving of the side's of comprising tongue, latch bolt, mechanical key composition also; System is sent to the square tongue signal pins of single-chip microcomputer integrated circuit to square tongue signal by square tongue, the latch bolt signal is sent to the latch bolt signal pins of single-chip microcomputer integrated circuit by latch bolt.

When Mifare card knowledge card circuit receives outside Mifare card signal, knowing the card circuit by four pin of single-chip microcomputer integrated circuit with the Mifare card is connected, receive the Mifare card and know the Mifare card signal that the card circuit sends, whether system is correctly judged the Mifare card signal that receives, Mifare card signal correctness, hummer and green or red indicator signal pin output high level by the single-chip microcomputer integrated circuit carry out acousto-optic hint, wherein, hummer sends the auditory tone cues of Mifare card correctness, show Mifare card correctness by a bright green or red led, if the Mifare card signal is correct, then export high level to opening drive circuit by the motor signal pin of single-chip microcomputer integrated circuit, then drive the electric motor clutch parts of lock by the opening drive circuit output signal, realize the unlatching of lockset.

When magnetic card knowledge card circuit receives outside magnetic card signal, knowing the card circuit with magnetic card respectively by three pin of single-chip microcomputer integrated circuit is connected, receive magnetic card and know the magnetic card signal that the card circuit sends, whether system is correctly judged the magnetic card signal that receives, magnetic card signal correctness, hummer and green or red indicator signal pin output high level by the single-chip microcomputer integrated circuit carry out acousto-optic hint, wherein, hummer sends the auditory tone cues of magnetic card correctness, show the magnetic card correctness by a bright green or red led, if the magnetic card signal is correct, then export high level to opening drive circuit by the motor signal pin of single-chip microcomputer integrated circuit, then drive the electric motor clutch parts of lock by the opening drive circuit output signal, realize the unlatching of lockset.

Hotel's lock of a kind of Mifare card, both compatibilities of magnetic card is lock core interface and the driving of the side's of comprising tongue, latch bolt, mechanical key composition also; When the guest does not wish to be disturbed, system is transported to signal by square tongue the square tongue signal pins of single-chip microcomputer integrated circuit, the signal correctness, green or red indicator signal pin output high level by the single-chip microcomputer integrated circuit carries out acousto-optic hint, realize that door-locking system enters into the pattern of locking from the normal door pattern, thereby make things convenient for guest or meeting personnel better to have a rest, handle official business, reached " not bothering " prompt facility; When lawless person's want to force open the door burglary or when deliberately destroying door lock, system is transported to signal by latch bolt the latch bolt signal pins of single-chip microcomputer integrated circuit, the signal correctness, hummer and green or red indicator signal pin output high level by the single-chip microcomputer integrated circuit carry out acousto-optic hint, realize that door-locking system enters into alarm mode from normal mode of operation, reached anti-theft alarm function.
