4,, then forbid the cut-in point ignition system T3 time as still not connecting ignition lock in the time at T2;

5, the T3 time is to count when stopping to attempt the cut-in point ignition system, then recovers tight ring state through behind the T3,

6, from turn-offing the ignition lock meter through T4 after the time, vehicle is in tight ring state;

7, in T1 time and T2 time, available radio is passed the signal that the someone contacts vehicle automatically back;

8, send stronger alerting signal in the T2 time;

9, the car owner can check after receiving signal whether the someone steals car, and can end robber's crime.

Device of the present invention is achieved in that

It is by (1) detector, (2) T1 timer, (3) T2 timer, (4) T3 timer, (5) actr, (6) countdown circuit, (7) warning circuit, (8) receptor, (9) and composition such as door grade.As shown in Figure 1.Its input connects the Acc line of (10) ignition lock.Output contact ignition system (11).

When detector can detect the someone and contacts vehicle because the fricative electric signal of car key and lock, or because the electric signal that produces owing to the variation of battery tension during electricity consumptions such as the door of driving, its mouth is connected with the input end of T1 timer, and the mouth of T1 timer is connected with the input end of T2 timer and the power control terminal of transmission circuit respectively.The mouth of T2 timer is drawn into end with the control of the input end of T3 timer and warning circuit respectively and is connected, the output of T3 timer is connected with the input end of executive circuit, the mouth of executive circuit is connected with ignition system on the car, and the Acc line of ignition lock is connected respectively with two input ends of door with the mouth of T3 timer.

The present invention drives and locks car that by custom following good effect is arranged owing to adopt former car key to prescribe a time limit in proper order:

1, need not remember that concerning the car owner password need not carry electron key or cipher remote control device yet, need not do additional action, easy to use, can complete hidden installation.

2, concerning the robber, attempt is unblanked not open with different keys explorations in T1 and T2 time (about 30 seconds usually), the picking lock wiring also to have little time.And this moment, the car owner received alerting signal can check whether the someone steals car.When stealing car if any the people, the time of T3 (about 2 ∽ 15 minutes) is on the scene to the car owner.The crime that catches a thief or end him provides guarantee, is safe.

3, circuit is fairly simple, the reliability height.Cost is low.

Embodiment

Accompanying drawing 2 is structures of vibration detector, and accompanying drawing 3 is electrical schematic diagrams of motorcycle anti-theft alarm.

Vibration detector is by (11) piezoelectric ceramic piece, and (12) are suspending hammer fixedly, (13) suspended pendulum, (14) pillar, compositions such as (15) amplifying circuit.Suspended pendulum is hook solid, and the one end has a garden ring set in the hole, garden at piezoelectric ceramic piece edge, and the other end is a metal, and hammer is the arbitrary equilibrium state.Piezoelectric ceramic piece is fixed in the printed board by pillar, and printed board is fixed on the base of annunciator, and annunciator is fixed near the lock body.One end ground connection of piezoelectric ceramic piece, the input end of another termination amplifying circuit, amplifying circuit have potential device W1 to adjust sensitivity, and the mouth energising resistance r1 of amplifying circuit is connected with the C end of binary pair IC1.And be connected with the D end of IC1 by diode d1 and integrating circuit r2, c1, constitute the T1 timer, the R of r3, c2 and IC1 and r4, c3 formation T2 timer, its mouth Q is connected with warning circuit IC3 by resistance r7.The mouth Q of IC2 is connected with the R end of c5 and IC2 by r6 and S end and c4, the r5 of IC2 are connected to form the T3 timer.T3 timer output end Q is connected with the base stage of T1 pipe by r7, constitutes executive circuit by T1 pipe and relay J, and its open contact is connected with ignition system.Private circuit IC3 and aerotron T2, T3 and voltage transformer B and piezoelectric ceramic piece YD2 constitute warning circuit and electronic horn.Resistance r10 and diode d3, d4 and aerotron T4 resistance r11 and diode d5, d6 form two AND circuit, are connected with the Acc line of ignition lock after the end of r10, r11 is connected.Aerotron T5 and resistance r12 diode d7, d8 form countdown circuit, and its mouth is connected with the power lead of emitter.

Under the tight ring state when the attempt of human key is unblanked, because the friction of key and lock body produces vibration, amplifier has output signal and through r2, c1 integration, when when T1 for once rubbed in (the about 10 seconds) time, its integral voltage out of reach high level, as can connect this moment ignition lock then C2 charging IC1 reset and can not report to the police.As take place in the time at T1 more than three times friction or continuous vibration, move the Q end output high level that integral voltage then arrives high level IC1, warning circuit is reported to the police, the emitter emission, the T2 timer begins regularly, the car owner is on the side in this way, also available former car key is connected ignition lock IC1 is resetted at this moment, can drive, as the car owner not the other then available warning that constantly resets receiver of car judge whether the someone steal car (time of fire alarming above T2 then the someone steal car).If continue in the time that at T2 people's motor-car is arranged, this moment, C3 was charged to high level, the output signal of amplifier makes IC2 trigger Q output high level, the T3 timer begins regularly (r6, c5 charging), the T1 pipe can not adhesive of turn-on relay J, and ignition lock can not switching on the ignition circuit, promptly uses former car key this moment, attempt is driven, and can not start vehicle.And the value of T3 can be set by the car owner, has only the car owner just to know, even other people has connected ignition lock also because charging only can prolong the taboo expected time of arrival and departure and can not start vehicle to C4 at T3 in the time.Connect ignition lock as nobody at T3 in time, then IC2 resets when T3 finishes.

C2 enters tight ring state by the r3 discharge through T4 after turn-offing ignition lock after the time.
