Description

A kind of remote control password lock

The utility model relates to lockset, particularly a kind of electronic lock of opening with the cipher remote control mode.

The tradition lockset of key, the one, key is how very inconvenient, needs from a pile key, recognize corresponding key, the 2nd, safe coefficient is not high, is difficult to tackle the burglar of special skill.Occurred multiple novel electron lock in recent years on the market, contact has been arranged,, had contactlessly, locked as automobile remote-control as IC-card formula, keyboard-type etc." electron key and the electronic lock " that Chinese patent 96120743 provides has the advantage that password is difficult for being decrypted, but has a plurality of buttons to be used to send different instructions on its electron key, and the user is in use if careless touch of key-press by accident then misoperation can take place; In addition, its electronic lock is equipped with two electromagnetic valves, and manufacturing cost improves.

The purpose of this utility model provide a kind of button operation convenient, accurately, the power consumptive province, can open a plurality of different passwords, remote control password lock that safe and secret degree is high.

The utility model is made up of electronic lock and electron key, and electronic lock is reached by infrared receiver tube, electric device to be made up of the mechanical lock core apparatus of its control, and its password is formed by dynamic coding and two groups of password combination of solid-state coded; Electron key is by infrared emission tube HF is housed ₂And the remote-control box of solid-state coded chip formation, it is characterized in that also including an independence and infrared transmitting tube HF is housed ₁And the remote-control box of dynamic coding chip, wherein the dynamic coding chip output is connected infrared transmitting tube HF with the base stage of a triode ₁Connect with this triode; An output of solid-state coded chip is connected infrared transmitting tube HF with the base stage of a triode ₂Connect with this triode; Be connected with decoding chip and storage chip and the electric device drive circuit of testing code function between infrared receiving tube and the electric device.

In order to save static power consumption, above-mentioned infrared receiving tube can be by main receiving tube HJ ₁With auxilliary receiving tube HJ ₂Form, the conducting by the triggering of auxilliary receiving tube of main receiving tube is wherein with main receiving tube HJ ₁The transistor base of an output series connection connects the Vss end of decoding chip, and the P1.2 end of this chip is connected with the output of the power discharging transistor of assisting receiving tube, thereby makes big power consumption receiving tube HJ ₁Be in electricity-saving state during inoperative.

A button of connecting with power supply is only arranged on the above-mentioned electron key remote-control box, and what have a multiple cipher solid-stately deceives that all passwords can be by the once all emissions of this button in yard chip.

Electric device can be that electromechanical such as micro machine or electromagnetic valve are changeed a device.

Remote control lock provided by the utility model:

One, owing to adopts dualistic coding, wherein the dynamic coding device not carried as side-arm carry, and the regular coding body is long-pending less, conveniently carry as key, even lose, another group password can not gone into to decode yet, decoding circuit has the code function of testing in addition, unlocking mechanism just can move when having only combinational code to accord with entirely, moreover the combination of two groups of passwords can reach several hundred million kinds, the level security height.

Two, owing on the electron key box button is only arranged, only this button need be pressed during use, maloperation can be do not caused.

Three, because general electronic lock is made power supply by dry cell, and main receiving tube function consumption is bigger, has adopted it to need to trigger the just circuit of conducting by auxilliary receiving tube, has saved power consumption, has prolonged the battery altering cycle.

Four, an electron key can be opened a plurality of locks.Each lock deposits the Different Dynamic password respectively in, and the solid-state coded device in the electron key can deposit in advance and reach tens of groups of passwords, presses the button of electron key, can be with the once all emissions of all passwords, and electronic lock carries out verification one by one to the password that receives, as long as there is one group to meet, just can open the door.

Embodiment is provided by accompanying drawing.In the accompanying drawing, Fig. 1 is a dynamic coding remote controller electrical schematic diagram, and Fig. 2 is a solid-state coded remote controller electrical schematic diagram, and Fig. 3 is the electronic lock electrical schematic diagram, and Fig. 4 is the two infrared receiving tube circuit diagrams of electricity-saving type.

Be described further below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 2, dynamic coding device and solid-state coded device constitute remote-control box separately.The dynamic coding chip IC ₁Adopt commercially available MCYYH type coding chip, its input A.-Am is used to input password, its output 0 ₁Connect and infrared transmitting tube HF ₁The power tube BC of series connection ₁₈Base stage.K successively pushes button ₀-K _mIn coding, infrared tube HF ₁Be the sequential transmission password and received, use when being used to password is set by infrared receiving circuit.The solid-state coded chip IC ₂Adopt commercially available 12C5xx type coding chip, manufacturer writes multiple cipher in advance by lock, and its output 2 connects and infrared transmitting tube HF ₂The power discharging transistor BG of series connection ₁₃Base stage, switch key K connects with power supply E, presses K, is stored in IC ₂All the group passwords promptly by infrared transmitting tube HF ₂Sequential transmission is also received by electronic lock, as electron key.

With reference to Fig. 3, infrared receiving tube HJ ₁Adopt commercially available triple-pole type 3PIN, decoding chip IC ₃Adopt commercially available 87LPC764 type, storaging chip IC ₄Adopt commercially available X25045 type, when password is set, infrared receiving tube HJ ₁Receive send by the coded telecommand box the one group dynamically combination dynamic password that sends of sign indicating number and electron key successively, and selected wherein one group dynamic yard, through triode BG ₁, BG ₂, BG ₃The casacade multi-amplifier of forming outputs to decoding chip IC ₄10 ends, IC ₄The 1st end and 1C ₃5,2 ends connect, password enters storaging chip IC ₃, password setting is finished.Such as locking factory at IC ₂Write 1-10 group password in advance, the user with the door be set at 1, the garage is set at 2, office door is set at 3, in each door lock all at IC ₃In deposit specific one group of dynamic sign indicating number in, when the key operated office door of user power utilization, press electron key button K, IC ₄After receiving 10 groups of passwords, automatically from IC ₄In access the solid-state sign indicating number that pre-deposits and dynamically sign indicating number carry out verification, if conform to IC ₄The 2nd and 3 ends output high level, trigger by BG respectively ₄, BG ₅And BG ₆, BG ₇That forms recommends motor-drive circuit, and micro machine S running, and dead bolt motion in the driving device lock core device realize unblanking purpose.

Because infrared receiving tube HJ ₁About the about 500mA of operating current, power consumption is big, is that the electronic lock user of the energy will can't bear the battery heavy burden for battery.Design another embodiment shown in Figure 4, small-power infrared receiving tube HJ for this reason ₂Be normal duty, HJ ₁Be dormant state then, work as HJ ₂When receiving unlocking signal, BG ₉-BG ₁₂Work, BG ₁₂Output to IC ₄P1.2 end, open from the output of Vss end that signal adds to and HJ ₁The BG5 base stage of series connection, HJ ₁Enter duty, thereby make HJ ₁Power consumption greatly reduces, and has realized prolonging the purpose of battery life cycle.
