Description

Fingerprint Lock

The utility model relates to a kind of electronic lock class technology, is a kind of Fingerprint Lock.

More, the general mechanical lock of kind of existing lock assembles by machine components, adopts key unlocking, and its confidentiality is relatively poor, so long as identical key just can be opened lock; As at present all automobile door locks, home-use lock etc., its theftproof performance is relatively poor, is not suitable for being contained in place antitheft and that security performance is had relatively high expectations; The other coded lock is opened by different combined digitals, though antitheft and security performance increases to it, its number of combinations is made up by 0～9 tens word, does not have 100% confidentiality.

The utility model is at above-mentioned situation and according to the different a kind of electronic fingerprint locks that provide of everyone fingerprint, compares and by the unlatching of circuit control lock according to scan transfer to the user fingerprints storage center to resident family's fingerprint.

The purpose of this utility model realizes in the following manner: it includes body, locking bolt, the locking bolt opening tool of lock, and it also has the pintle hook lock that is used to block locking bolt, and pintle hook lock is positioned on the body of lock or is positioned on the door regularly by elastic component; Pintle hook lock is controlled by electromagnetic coil, and electromagnetic coil links to each other with circuit by line.Described circuit includes transformation current rectifying and wave filtering circuit, central control circuit, ic chip 3, fingerprint scanner CP, amplifying circuit and locking bolt control circuit.

Fingerprint Lock of the present utility model has higher confidentiality and automaticity height; Be convenient to and computer networking, change the password of lock at any time, have higher theftproof, can be widely used in fields such as hotel, automobile, family expenses door lock.Because the utility model is to adopt fingerprint to unblank, so and people's fingerprint do not have in the world identical non-be to unblank in person, so its theftproof performance is fabulous, security performance is quite high, and this Fingerprint Lock also can be adapted to banking secrecy department or attendance checking system etc.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is a basic structure schematic diagram of the present utility model;

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

Referring to Fig. 1, Fingerprint Lock of the present utility model includes body 1, locking bolt 2, the locking bolt opening tool 3 of lock, and has the pintle hook lock 4 that is used to block locking bolt 2, and pintle hook lock 4 is positioned on the body 1 of lock or fixedly is positioned on the door by elastic component 5; Pintle hook lock 4 is controlled by electromagnetic coil 6, and electromagnetic coil 6 links to each other with circuit 8 by line 7.There are structures such as the body that shuts and locking bolt can adopt existing lock construction; Select the situation difference for use according to it, its locking bolt opening tool 3 can be the handgrip that links to each other with locking bolt; Also can be the key of control lock bolt, at this moment be the double insurance lock that a kind of mechanical lock combines with Fingerprint Lock.

Referring to Fig. 2, above-mentioned circuit 8 includes transformation current rectifying and wave filtering circuit, central control circuit and peripheral circuit thereof, ic chip 3, fingerprint scanner CP, amplifying circuit and locking bolt control circuit; Central control circuit adopts BEC586, can pass through the online control of main control computer, and relevant central control circuit and peripheral circuit thereof all adopt existing circuit, are not described in detail at this.Fingerprint scanner CP links to each other with pin 19 and the IC3 of BEC586, and ic chip 3 links to each other with the pin 28,33 of BEC586; And ic chip 3 links to each other with the colelctor electrode of triode T1, and the base stage of triode links to each other with the pin of BEC586 10; The output pin 22 (A1) of BEC586 links to each other with amplifying circuit; Amplifying circuit is made of triode T2; The locking bolt control circuit is made of triode T3, T4, T5, T6 and T7 etc., the colelctor electrode of triode T7 links to each other with triode T3, the colelctor electrode of triode T6 links to each other with triode T4, be connected with relay J between triode T3 and T4, the base stage of the base stage of triode T2 and triode T3 links to each other with the output pin 22 of BEC586.

Above-mentioned IC3 adopts 24C01A.

The utility model earlier becomes digital code to the fingerprint input computer that needs unlocking person in use, and to transfer to the tapered end memory be on the IC3 to the digital code of computer then, stores.When the fingerprint scanner CP that touches tapered end when people's fingerprint goes up, just people's fingerprint become digital code through the pin 19 of BES586 enter and reach by pin 28,33 IC3 goes up and memory on digital code compare, T1 feeds back to BES586 by triode; Conform to as digital code, by the A1 pin output signal of BEC586, amplify through triode T1, make the relay J adhesive through the locking bolt control circuit again, circuit is connected, coil 6 energisings, and adhesive pintle hook lock 4, thus open locking bolt 2 by locking bolt opening tool 3, realize the purpose of unblanking; Otherwise if digital code does not conform to, circuit is obstructed, and relay disconnects, and pintle hook lock 4 blocks locking bolt 2, can't unblank.Reach antitheft secret effect.
