Description

The high secret electronic lock of key-type

Technical field

The utility model relates to a kind of lockset, particularly relates to the high secret electronic lock of a kind of key-type.

Background technology

On the market multiple electronic lock is arranged now, structurally all comprise single-chip microcomputer and the LCD, keyboard, lock executing agency and the power supply that are attached thereto.Can be divided into following several types by the mode difference of unblanking: 1, key number code type: password can not be oversize, otherwise do not remember, and short password is guessed right easily, and confidentiality is not strong; The function of checking each other that can not support two people to show up simultaneously just to unblank, or dual fail-safe measure.2, magnetic card type: magnetic stripe damages easily, and the demagnetization that is magnetized damages the cost height easily.3, IC-card type: card damages easily, the cost height.4, non-contact type:, under contactless state, give away secrets the cost height easily as radio frequency, RFID etc.5, bion:, have the wrong problem of identification, the cost height as finger pattern.Above-mentioned all electronic lock ubiquity functions fix, dumb, can not adjust the problem of function according to user's needs.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of key-type high secret electronic lock.

For achieving the above object, the high secret electronic lock of the utility model key-type comprises LCD, the keyboard of single-chip microcomputer with lock logic circuit and lock executing agency, power supply, indicator lamp and the apolegamy that is attached thereto, its special feature is that single-chip microcomputer also is connected with a four-wire interface, and four-wire interface is furnished with the Four wire plug formula key of a plurality of band storage chip.Single-chip microcomputer store identification and manipulative procedure, the Four wire plug formula key of band storage chip has corresponding overlength password, and with the Four wire plug formula key insertion four-wire interface of band storage chip, single-chip microcomputer is the identification key cipher automatically, and is very easy to use.The Four wire plug formula key of described band storage chip has a plurality of.So design, the key that adopts the band storage chip are as unlocking cipher, and more convenient employing overlength key (is 1024 bits as length) is difficult for being guessed right strong security.Adopt the general-purpose interface of the direct way of contact of four lines between key and the lock body, data transmission capabilities is big, and cost is low.Lock body adopts general single chip and program to discern and control, and identification is accurate, strong security, and flexible function, cost is low.It has that cost is low, strong security, flexible function, change on demand, the convenient advantage of using.

As optimization, described four-wire interface is a USB formula interface, and Four wire plug formula key is a USB formula key.Then highly versatile of USB interface and USB formula key is adopted in so design, can directly adopt the generic USB interface and the common U disk interface of a large amount of productions and widespread usage.And key adopts small-sized USB flash disk form, and is attractive in appearance and be easy to carry, also not fragile.

As optimization, single-chip microcomputer also is connected with phone or fingerprint collecting recognition device or button numerical ciphers recognition device interface.Make things convenient for the described ancillary service of adapted.

As optimization, described Four wire plug formula key is multiple more than three kinds or three kinds.So design, the convenient unlocking authority that distributes.

As optimization, one of them Four wire plug formula key is to be used to register the franchise key of newly unblanking key, cancelling and having key, set uncaging time and setting unlock mode, a reserve key that uses when being the normal key loss, other is the normal key that is used for unblanking at ordinary times.So design, the user just can have one " franchise key " and some handles " normal key ", and " a reserve key " that uses when normal key is lost.Can be arranged to " single key pattern ", " double key pattern " or " three key patterns " to improve privacy degrees with franchise key according to user's needs.Unlock mode can be changed at any time by programme-control, need not change lock.

Can register new normal key with " franchise key " according to user's needs, or the existing key that cancels; Can set uncaging time with " franchise key " according to user's needs, non-uncaging time does not have franchise key not unblank; Can set unlock mode with " franchise key " according to user's needs, comprise that single key unlocking, double key are unblanked, three key unlockings etc.; When normal key is lost, can make waste and old key with old key number by " franchise key ", old key just can not use; And register new key, then need one " normal key " or " reserve key " to cooperate at least, in order to avoid " franchise key " abused.

Can set unlock mode with franchise key, comprise: single key unlocking pattern, promptly any one inserts four-wire interface to normal key or reserve key can unblank alone; The double key unlock mode promptly needs two normal key or reserve key to insert four-wire interface successively, just can unblank; Three key patterns promptly need three normal key or reserve key to insert four-wire interface successively, just can unblank, and the like.

When normal key is lost, can unblank by " reserve key "+" normal key ".The reserve key is once use, and lockset is initialization, and leaves vestige, and all keys need re-register, and prevents that the reserve key from being abused, and prevents that simultaneously the key of losing from illegally being used.Can export the record of unblanking, inquiry for future reference with " franchise key " according to user's needs.

As optimization, single-chip microcomputer also is connected with fingerprint collecting recognition device or button numerical ciphers recognition device.So design increases by " button numerical ciphers recognition device " or " fingerprint collecting recognition device ", can support the form of unblanking of " key+key number password " or " key+fingerprint ".

As optimization, single-chip microcomputer also connects telephone wire by phone module.So design increases " phone module " and connects telephone wire, can Advise By Wire or SMS notification or alarm when unblanking.Function can also need not more renew lock by software upgrading.

After adopting technique scheme, the high secret electronic lock of the utility model key-type has that cost is low, strong security, flexible function, change on demand, software upgrading, and convenient the use, key is easy to carry, not fragile, advantage that the authority kind is various.
