It is such designing basic design of the present utility model:
We wish that at first it has the function of general electronic password lock is that the password of each lock can change, and enough multiple variation possibilities should be arranged, correct when unblanking as long as import password at every turn, lock is opened immediately, secondly use two keys to replace the keyboard of conventional coded lock, be beneficial to and prevent pounding, use two keys can input password, sign indicating number, triggering doorbell and under-voltage detection and warning device can also disappear simultaneously.
Based on above-mentioned imagination in detail, the composition and the operating principle of each functional unit of solution is described in detail below in conjunction with accompanying drawing:
Said power supply adopts No. 5 batteries of commercially available eight joints, equipped with battery groove 16 in the casing, the positive and negative contact 9,10 of power backup interface is established in handle 8 inboards outdoors, diode VD1 and VD2 isolate two cover power supplys, battery is the power supply in limited time of other unit through electronic switch, the conducting of triode V1, the V2 of said electronic switch unit or end, the power supply of decision electronic switch opens and closes, the power-on time T of capacitor C 1 and resistance R 1 decision electronic switch.When static state, button S1 disconnects, and capacitor C 1 end is pressed to high, and triode V1 and V2 end, and electronic switch ends, and output voltage is zero, the quiescent current microampere order.Press the S1 key once, capacitor C 1 is discharged rapidly, is recharged triode V1, V2 conducting again thereupon, electronic switch output voltage+V also keeps T second, simultaneously, when pressing the S1 key and inputing each password and count, as long as the adjacent arbitrarily time interval of pressing for twice is less than T second, supply voltage+V is then arranged all the time, and press for the last time after the S1 key, electronic switch is continued power T second also, and said under-voltage detection and doorbell unit are with triode V4, NAND gate IC7, Schmidt trigger ICl
cWith buzzer HA be core, wherein IC7
a, IC7
bConstitute audio frequency oscillator, NAND gate IC7
c, IC7
dDrive buzzer HA, triode V4 constitutes the detection level, determines the under-voltage threshold values of battery according to the action message electric current of electromagnet DT, and the resistance that changes resistance R 13 can be provided with under-voltage threshold values, when if cell voltage is higher than threshold values, press the S1 key once, triode V4 conducting, collector voltage is low, the oscillator starting of oscillation, buzzer HA rings T second rapidly, and the expression battery still can use, simultaneously as doorbell.Otherwise, pressing the S1 key, triode V4 ends, and buzzer HA does not ring, and explanation should more renew battery.
Said singly-bound pulse I, singly-bound pulse II Unit two are with two key S1, S2 and Schmidt trigger ICl
a, ICl
bBe core, its 26S Proteasome Structure and Function is identical, is used for producing counting and quenching pulse, as presses the S1 key once, and an IC1 output Millisecond (being decided by resistance R 5 and capacitor C 3) pulse is pressed S1, S2 once, Schmidt trigger ICl simultaneously
a, ICl
bThe two-way pulse of output is through yard pulse synthesis unit that disappears, and zero clearing order count device IC3 and stepping mnemon IC5, IC6 work the sign indicating number effect that disappears.
Said password counting unit is core with decade counter IC2, is linked to be the counting enabled state, receives the ICl in the singly-bound pulse I unit
aThe count pulse of output is each input password counting, the ICl in the singly-bound pulse II unit
bThe pulse of output is prepared for password counter IC2 receives the next bit password through time delay process resistance R 8 and capacitor C 6 zero clearing IC2, and " 0 " of password counter IC2～" 9 " end is with stepped form output high level.
The password preset unit is made of four decimal system dial switch B1～B4, and 0 to 9 input of dial switch B1～B4 is corresponding in parallel, corresponding again " 0 " to " 9 " output that is connected to IC2.Four output e of B1～B4
1～e
4Corresponding 42 inputs and door IC4 of sending the stepping control module
a～IC4
d, to press the button that adds deduct on every dial switch and can give easily and put decimal system password, password can be from window 18 direct-views.Therefore, press the S1 key n time, import a password and count n to IC2, the output that then gives that dial switch of putting several n of being among B1～B4 becomes high level.
Order count device unit is a core with decade counter IC3, is connected into the counting enabled state, receives singly-bound pulse II unit ICl
bThe count pulse of output.IC3 output " 1 " to " 4 " correspondingly send the IC4 in the stepping control module
a～IC4
dOne of two inputs, as the stepping control signal of four passwords inputs, output " 5 " to " 9 " forms the coded signal that disappears, this unit of zero clearing and stepping mnemon through isolating diode VD8～VD12.Zero clearing work when differentiation element C7 and R9 are responsible for IC3 and power up.
Because the high level of IC3 output has stepping, so after IC3 and power connection make the IC3 automatic clear, press a S2 key, then with door IC4
aOpen, allow the output e of B1
1By.By a S2 key, open and door IC4 again
b, simultaneously with door IC4
aClose, allow the output e of B2
2By.The result is that order is by S2 four times, with door IC4
a～IC4
bOrder is opened, and makes e
1～e
4Order is passed through.Continue to press S2 again, then zero clearing IC3 and IC5～IC6 work the sign indicating number effect that disappears, and when IC3 counted up to 9, output " 9 " uprised level, as alarm trigger signal X, can give the corridor internet alarm system outward.
Stepping mnemon is made of d type flip flop IC5～IC6.Four d type flip flop levels are linked to be the stepping chain, and clock CP1～CP4 is successively from the IC4 of stepping control module
a～IC4
dOutput.When voltage+V occurs,, make stepping mnemon enter initial state through differential circuit R10 and each trigger of C8 zero clearing.When having only CP1～CP4 to obtain rising edge in proper order, first trigger IC5
aThe high level of D end just can step to the 4th trigger IC6
bOutput as the control signal of unblanking of stepping mnemon output.
Therefore, have only to input as follows and put password n identical on B1～B4 with giving
1～n
4The time, just can obtain unlocking signal: simultaneously by two key S1 and two counters of S2 zero clearing and stepping mnemon, according to pressing S1 n fast
1Inferior, fast reaching by a S2 inputed first password n like this
1In like manner input back three password n
2～n
4, when pressing S2 the 4th time, stepping mnemon is promptly exported the control signal of unblanking.
The coding and decoding array of four decimal system passwords shown in Fig. 2, size of key 10
4Copy that password presets, the structure of stepping control and memory and four unit of order count, be easy to the password figure place is extended to nine.
Driving stage is made up of triode V3 and resistance R 12.The time-delay reset unit is by integrating circuit R1 and C9(time-delay T
1Second) and isolating diode VD13 composition.When control signal is unblanked in the output of stepping mnemon, the V3 conducting, electromagnet DT2 gets electric, the pin 3 in the sucking-off lock body, it is spacing to remove locking bolt 5.Stir outer handle 8, take out the bolt of unblanking and open the door.The control signal of unblanking is sent time-delay reset unit, T
1Second (T
1＜T) after, through diode VD13 zero clearing stepping mnemon, the control signal of unblanking is disappeared, triode V3 ends, electromagnet DT dead electricity, pin falls, and goes into behind the door, handle 6 is sent locking bolt in the manually operated door, pin falls into stopper slot 4, fastens locking bolt.When going out, pinning switch S 37, that DT is got is electric, and handle is unblanked in the manually operated door, has also carried out voltage detecting simultaneously.
If make the two key formula electronic password locks control of same two covers circuit emergency interface each other, only needing driving stage triode V3 in two covering devices is in parallel at its colelctor electrode, emitter stage gets final product, and other is installed roughly the same.Total and installation are referring to accompanying drawing 3.
