Description

Multifunctional electronic lock

The utility model belongs to the protection mechanism of door, particularly needs the lockset that uses on the emphasis defendance door.

At present, in high-grade hotel, office building, bank and other places that need lay special stress on protecting, extensively mechanical lock and Photoelectric lock of bringing into use and the magnetic card lock that adopts owing to many-sided reasons such as design, quality, is difficult to take precautions against larceny case.Its subject matter is:

Mechanical lock: a, key are easy to copy, the tongue parts of b, lockset are easily because of installing improper or wearing and tearing, promptly lose the anti-usefulness of allocating for, c, can not provide time of door open and close, use records such as keyed feature, d, not in place locking a door, the state that door is left unlocked or unlatched is reactionless, the frequent replacing user of service and the loss of e, key can make corresponding single or multiple door lock lose security performance, can bring heavier financial burden to the user and often change door lock.

Photoelectricity key lock: a, key card adopt plastic tab to add a few metals contact and punch and form, and are easy to copy, and the house spring parts of b, lockset are because of installing improper or wearing and tearing, promptly lose the anti-usefulness of allocating for, c, can not provide time of door open and close, use records such as keyed feature, d, not in place locking a door, no prompt facility, e, can not provide records such as door is opened, closed, power direction, source, use key basis, f, complex structure are easy to be out of order, maintenance difficult, costs an arm and a leg at g.

Magnetic card key electronic lock and the phase-locked comparison of photoelectricity key electronic, except that adopt the magnetic recording card do key card be difficult for imitated, other problems is identical.

The purpose of this utility model is, designs a kind of novel multifunctional electronic lock, and it adopts single-chip microcomputer, and the mechanical part of door lockset is implemented control, and its performance and price are compared with photoelectricity and magnetic card, and be stable and reliable for performance, relative low price.

Multifunctional electronic lock of the present utility model, form by lock body, dead bolt, inside and outside handle and electronic control part and wireless encoding signal emission element, dead bolt is connected with lock body, handle is connected with lock body by the handle neck, it is characterized in that: the component room of posting a letter is set above the interior handle neck of lock body, and the below is provided with the power supply of posting a letter; The electronic control part chamber is set above the handle neck outside lock body, and the below is provided with microcontroller power supply; Wireless encoding signal emission element is connected emitter with single-chip microcomputer; Electronic control part is connected with program storage, data storage, clock circuit by single-chip microcomputer, inner handle sensor, outdoor handle sensor, tongue sensor, door location determination circuit are connected to single-chip microcomputer, and top, electronic control part chamber is provided with the key socket; On lock body top diectric antenna is set, on inside and outside handle neck microswitch is set, single-chip microcomputer is connected with electromagnet, buzzer;

Key adopts international IC-card.

Mode of occupation: will use data as: unit code, key block encoding, tenant's coding, time encoding, encrypted code input IC-card, as the key of lockset.After IC-card inserts the key socket, when data require to conform to this lock, inner handle sensor, outdoor handle sensor, tongue sensor, door decision bits circuits are delivered to the electronic control part chamber with the action open and close signal of telecommunication of corresponding inside and outside handle, tongue and door respectively, the outdoor handle control circuit is the joint portion of lockset electronic control part and mechanical part, the rotation of outdoor handle is opened or is closed in instruction according to single-chip microcomputer, could be opened by the outside with the control door; Not in place when the tongue of closing the door, door is in is left unlocked or unlatched status number after second, starts the Tip Sound circuit, and the state of being left unlocked or unlatched is removed, and this circuit is removed prompting.The electron key that conforms to when nothing inserts and door when being opened by the outside, the time that electronic control part chamber record takes place, start wireless encoding signal emission element simultaneously, outwards transmission content is the wireless signal of door numbering, coverage is interior 50 meters an of building, the receiver that is installed in floor desk and link security authority wired with it is in often keeps listen state, when receiving this signal, send the buzzing sound equipment, charactron shows door numbering and time of origin, and this state finishes when removing button and be pressed; Every data of record all can be accessed also and can be printed by special equipment in the lock.

Multifunctional electronic lock of the present utility model, key adopt IC-card, and the electronic data memory of big capacity or vast capacity is encapsulated in the plastic tab, memory capacity can be by 512 bit to 4 megabit bits, and its storage data are reliable, and playback mode is easy, imitated difficulty, key code does not have repetition.Not only lockset perfect in shape and function also has the unusual reflection ability of opening of door, and can provide accurate data to the work after the crime.Compare with anti-other locksets such as mechanical lock, photoelectricity key lock, magnetic card lock of dialling,, all have very big advantage at aspects such as function design and economic performance compare.

Multifunctional electronic lock of the present utility model is applicable on the door of need emphasis defendance such as each high-grade hotel, office building, bank, apartment, commercial center and uses.

Below in conjunction with drawings and Examples multifunctional electronic lock of the present utility model is described further.
