Fig. 2 is schematic circuit diagram of the present utility model.
Among Fig. 2, YYH26/28 is novel codec IC, and using coder-decoder to encrypt is a kind of simple and reliable method.The one group of password that is produced by coder is sent to demoder in the mode of serial, demoder repeatedly compares password that receives and the password that itself produces (address code that decoding line is formed) continuously, if through still consistent after repeatedly comparing, then on corresponding pin, export control signal, the expression decoding is correct, otherwise then represent decoding error, thereby realized the design function under the highly confidential condition.YYH26/28 adopts four attitude coded systems, and wherein 1~8 pin, 10~13 pin are this address code.Except that the 1st pin had only three kinds of states, all the other can have four kinds of encoding and decoding states, that is: ground connection VSS is unsettled; Meet VDD or link to each other with the 1st pin.It is the address code of codec that the utility model adopts 1~8 pin of YYH26/28, and worker's attitude is used: ground connection or unsettled, effectively the marshalling sign indicating number is 2
8=256 groups.10 pin of the YYH26~equal ground connection of 14 pin, 10 pin of YYH28~13 pin are ground connection also, and wherein 14 pin of YYH26 are the coding output control terminal, and during ground connection, YYH26 is just by its 17 pin output encoder string.The utility model design substitutes master cock with the 14 pin dead earths of YYH26 with source switch SAO, and the one, handled easily, the 2nd, save the quiescent dissipation under on the alert, the 3rd, can increase secret and safe.
In keyboard circuit, fixed when the decoding line address code state that 1~8 pin of YYH28 is formed, the state of 1~8 code switch key SB5~SB12 of YYH26 should meet the decoding line state of YYH28, at this moment, can press SAO key on the keyboard, then export a pulse high level at 17 pin of YYH28.This high level one tunnel is input to ON-OFF control circuit 2VT1 base stage through KR2-2 normally closed contact, 2R1, finishes and unblanks.One the tunnel makes the 1VT1 conducting, 1VT2 and 1VT3 conducting in succession through 1C2 to 1VT1 base stage.The 3VT3 base potential is zero at this moment, and 3VT3 ends, and delay is blocked and the warning circuit dead electricity of prescribing a time limit is not worked.
In ON-OFF control circuit, when keyboard input proper password, 17 pin of 1IC2 are exported a control signal, and by the KR2-2 normally closed contact, 2R1 provides base flow to 2VT1, the 2VT1 conducting, and 2VT2 is conducting in succession.2VT2 is not before the conducting, 2C1 charges by 2R3, after the 2VT2 conducting, 2C1 discharges over the ground by KR1,2VT2 collecting electrode rapidly, at this moment, crosses bigger discharge current at the KR1 coil midstream, the KR1 adhesive, and, keep the KR1 adhesive with less current by after the 2R3 current limliting, this relay connection method is very valuable to reducing power consumption.Meanwhile, green luminotron 2VD1 is lighted, and indicating lock is unlocked.Open contact KR1-1, the KR1-2 of KR1 connects the automobile ignition coil power supply, and can start automobile ignition switch SBH this moment, finishes the normal startup of automobile.
Kidnap in the control circuit anti-, when automobile normal running, because of the 6 pin electricity of 4IC 1/3VCC, 2 pin do not have the negative going pulse energizing signal, so 3 pin of 4IC are low level, not conducting of 4VT.When automobile suffers unexpected the abduction, as long as the driver is with finger touch M sheet once, have induction impulse singla input because of 2 pin of 4IC this moment, 4IC overturn immediately (because of no RC constant loop, so 4IC does not make temporary steady operation), its 3 pin becomes high level provides base flow for 4VT after the 4R3 current limliting, at this moment, the mercury bulb in the mercury switch flows because of the fluctuation of running car suddenly left, suddenly rightly, and connects 4VT conducting loop, this moment, 4VD was lighted, and indication control effectively.Because the effect of 4VT conducting, the 2VT2 base potential of ON-OFF control circuit descend and approach zero, at this moment, 2VT2 ends, and KR1 discharges, its open contact point of cutoff ignition system power supply, and force the automobile auto shut down.In this process, because of the contact infeed stroke of mercury switch is very little, its joint angle degree of dip is between 7 °-10 °, and speed of response is exceedingly fast.If its speed of response is faster than the drop away time of KR1 and the discharge time of 2C1, then KR1 is in release position always, till automobile extinguishes parking.Whether can carry out restarting, this state that will see mercury switch behind the parking of automobile how.Before anti-abduction control circuit is not eliminated, both made repeated priming, all there is not any meaning, there is not any necessity yet.When the abduction accident is eliminated, the driver can carry out removing to the anti-control circuit of kidnapping, method is to remove strong SA1 touch-switch as long as point makes a movement, this moment, 6 pin current potentials because of 4IC rose to rapidly〉2/3VCC, its 3 pin then becomes low level rapidly, 4VD extinguishes, and the anti-control circuit of kidnapping of indication is eliminated, and is in stand-by state.Because 3 pin of 4IC are low level, 4VT is become by conducting and ends, and the 2VT2 base potential returns to normal value, the KR1 adhesive, and its open contact KR1-1, KR1-2 cut-in point ignition system power supply, can normally start this moment.
In keyboard delay blockade, the warning circuit of prescribing a time limit, because of YYH28 decoder decode state is fixed, operation keyboard when password bad, the serial pulses code signal (no matter this code signal of password correctness exists all the time) of the 17 pin output of YYH26 coder, be input to the 3VT1 base stage through 3C1, the 3VT1 conducting, 3VT2,3VT3 conducting in succession, the power supply positive voltage is exported from the 3VT3 emitter.This moment, power supply charged to 3C2 by 3R4, because of the 3C2 both end voltage can not consolidation, the 3R4 resistance is bigger, starting stage voltage all is added in the 3R4 two ends, 2 pin of 3IC/2, the current potential of 6 pin〉2/3VCC, 5 pin of 3IC/2 are low level, KR2 discharges, luminotron 3VD1 does not work, normal KR2-1 disconnection battle of KR2, and normally closed contact KR2-2 connects.Along with the prolongation to the 3C2 charging duration, 2 pin of 3IC/2,6 pin current potentials descend, and<during 1/3VCC, by the astable circuit upset that 3IC/2 forms, 5 pin are high level, and luminotron 3VD1 is lighted, and the indication keyboard is blocked when dropping to.Simultaneously, the KR2 adhesive, open contact KR2-1 connects, and normally closed contact KR2-2 disconnects.Determine by the value of 3C2,3R4 delay time.The utility model delay time was 10 seconds.At this moment, when 3C4 was high level at 5 pin of 3IC/2, moment was recharged, 3VT4 moment conducting, and 8 pin moments of 3IC/2 are imported a negative going pulse, make the monostable circuit of being made up of 3IC/2 enter temporary stable state, and stable state time t is determined by the value of 3R6,3C5 temporarily.Stable state time t is set to 3 minutes temporarily as requested.At the 9 pin output high level of temporary stable state 3IC/2 in the time, and trigger the pulse acoustical alarm work of forming by F1~F4 with direct-drive output high level input gating.The alarm work principle is as follows: when the 6 pin input high levels of F2, and the F2 upset, its 4 pin is a low level, 1 pin of F1,2 pin also are low level, the F1 upset, and its 3 pin is a high level, because the effect of 3C7,3R8, first gating unit of being made up of F1, F2 is in oscillatory regime.Driving pulse is input to 8 pin of F3 from 3 pin of F1, the F3 upset, its 10 pin is a low level, and 12 pin of F4,13 pin also are low level, the F4 upset, its 11 pin output high level, equally because of the effect of 3C8,3R9, second gating unit of being made up of F3, F4 is in oscillatory regime, and exports by 11 pin of F4 in the lump after the impulse singla of first gating unit and impulse singla itself that produce amplified, after the amplifier that direct drive is made up of 3V15,3VT6 amplified, SP sent chimes of doom by loud speaker.Because the oscillation frequency of first gating unit is lower than the vibration rate of Unit second, its warning tone is uprised by low in one-period, again by high step-down and quite ear-piercing, can play certain threatening effect to the car stealer.
When the 12 pin level of 3IC/2 increase the electrically-charged time of 3C5 because of power supply, and during 2/3VCC, 3IC/2 withdraws from temporary stable state.This moment, 3C5 discharged over the ground by 13 pin of 3IC/2, got ready for touching next time to put.9 pin of 3IC/2 are low level, and chimes of doom stops.The utility model time of fire alarming of prescribing a time limit is set at 3 minutes, and the value of adjusting 3R6 can change time of fire alarming in limited time.When if the proper password of input after the keyboard lockout meets YYH28 decoding line state, 17 pin of YYH28 are output as the pulse control signal of high level, be input to the base stage of 1VT1 through IC2, the 1VT1 conducting, 1VT2,1VT3 conducting in succession, this moment, the 3VT3 base potential was zero, 3VT3 ends, postpone to block, the warning circuit power supply disappears in limited time, and quits work.KR2 discharges, and luminotron 3VD1 extinguishes, and open contact KR2-1 disconnects, and normally closed contact KR2-2 connects, and keyboard lockout is disengaged.Because of having input control signal, ON-OFF control circuit enters mode of operation, the KR1 adhesive, and its open contact is connected the automobile ignition coil power supply, and can start automobile this moment according to a conventional method.
The effect of open contact KR2-1, normally closed contact KR2-2 is: when among the strong SB1~SB4 of the puppet on the car stealer mistake keypad when any key or control key SAO, if within 10 seconds, do not revise password, keyboard will be blocked, and send about 3 minutes ear-piercing chimes of dooms.The car stealer both made and disconnected pseudo-key or control key this moment, and all numerical keys, because of the effect of KR2-1, keyboard was blocked always.Meanwhile, the also input circuit of cut-off switch control circuit of normally closed contact KR2-2.Before not having the proper password input, can't remove at all.
When the car stealer only presses positive sign indicating number key except that SAO, SB1~SB4, because of password is known nothing,, still can't unblank though can not occur that keyboard is blocked and chimes of doom at this moment.Because of pseudo-key loads in mixture in positive sign indicating number key, confidentiality is very strong, and password is difficult to decode.
The user is when pressing the proper password operation keyboard, and its time also can only finish within 10 seconds, otherwise above-mentioned situation will occur.In actual the use, the user can press proper password earlier and select SB5~SB12 key switch state, need only press master cock SAO then and can realize unblanking.Because of all key switches all are that auto-lock function is arranged, operate easily.
The user should loosen all key switches (promptly disconnecting) before car, makes the keyboard zero clearing, does on the alert.The utility model this moment consumed power hardly, quiescent dissipation is humble.
ICW7806 is a three terminal regulator, and its effect is to make voltage for complete machine provides 6 stable couchers, to guarantee that performance is unaffected when 12 volts of voltages descend.
When the utility model was implemented, fixed mount 1, key panel 2, cabinet 3 all adopted metal work to make, and carry out surperficial spraying plating.All keyboard switches all adopt small-sized piano type self-lock switch, indicator lamp 4,5,7 is high brightness redness, green, yellow light-emitting diode, magnetic horn formula high pitch loudspeaker in loud speaker 6 adopts, clearing key 8 adopts small-sized touch-switch, touches sheet 9 and adopts copper clad plate processing and electroplate.
