Automobile alarm

The utility model relates to a kind of warning device that uses on the automobile that is installed in.

Less installation cab warning on the at present domestic automobile causes automobile situation stolen, that plundered more serious.And the automobile that has has been installed annunciator, it also is the trigger-type annunciator that adopts function singleness, the effect of this annunciator is when annunciator is in running order, the external object contact is arranged, cause automobile as breaking vehicle glass, pry open the car door compartment, drag the automobile of slinging away, when connecting the start-up system of automobile, all will triggering annunciator and send buzzing warning and light warning.There is following defective in this annunciator: (1) will completely lose warning function after the radio control frequency of annunciator is detected out; When (2) annunciator sent the warning distress signal, the start-up system of automobile was not cut off; (3) annunciator can't be taked suitable safety method to robbing car, robbing car.

It is a kind of multiple functional, highly sensitive that the purpose of this utility model is to provide, and has the auto alarm device of the function of antitheft, anti-snatch, anti-misfortune.

The utility model is to realize like this, this product is made of beeper, auto timer, trigger-type annunciator and circuit controller, beeper is connected with trigger-type annunciator and circuit controller respectively with auto timer, and the trigger-type annunciator is connected with circuit controller, and circuit controller then is connected with vehicle startup system; Beeper, auto timer and circuit controller are positioned at a side side by side, and the trigger-type annunciator then is positioned at opposite side.The circuit of product receives amplification latching circuit, timekeeping circuit, induction system, stable multi-oscillation circuit and warning circuit by the beeper signal and is formed.After beeper or auto timer receive signal current, electric current is input into trigger-type annunciator and circuit controller, bring out the trigger-type annunciator and send alerting signal, and the work of command circuit controller, cut off vehicle startup system.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is the utility model perspective view.

Fig. 2 is each structure connection diagram of the utility model.

Fig. 3 is the circuit diagram of the utility model.

The utility model is made of beeper (1), auto timer (2), trigger-type annunciator (3) and circuit controller (4), beeper (1) is connected with trigger-type annunciator (3) and circuit controller (4) respectively with auto timer (2), and trigger-type annunciator (3) is connected with circuit controller (4), and circuit controller (4) then is connected with vehicle startup system; Beeper (1), auto timer (2) are positioned at a side side by side with circuit controller (4), and trigger-type annunciator (3) then is positioned at opposite side.

In Fig. 3, this circuit receives amplification latching circuit, timekeeping circuit, induction system, stable multi-oscillation circuit and warning circuit by the beeper signal and is formed.Its operating supply voltage 12V, directly automobile power supply, this circuit direct current 12V voltage is through protective tube (FUSE), C ₁After the filtering, be fed to each element circuit respectively, resistance R ₁, R ₂, zener diode DW, diode D ₉Form dividing potential drop, shunting, mu balanced circuit respectively and provide working power to beeper (beeper).Resistance R ₃, R ₄, aerotron BG, relay J ₁, J ₂, button switch AN ₁Form the beeper signal and receive the amplification latching circuit.When beeper receives local launch pad signal, produce a signal voltage through R ₃Current limliting is added to the base stage of BG, and the base stage of BG becomes conducting, J by ending after voltage is arranged ₁Closure, since interlocking, J ₂, J ₃Also closed self-locking is simultaneously connected stable multi-oscillation circuit and warning circuit, and is disconnected Q point automobile starting line simultaneously.Ic chip ₁, resistance R ₅, potential device W ₁, capacitor C ₂, button switch AN ₂, relay J ₄Form timekeeping circuit.Regularly be to connect after 10 minutes, when pressing AN ₂The time, IC ₁2 pin zero clearings also pick up counting IC simultaneously ₁3 pin are in high level at ordinary times, and timing finishes IC after 10 minutes ₁3 pin become low level, J ₄, J ₃Simultaneously electric closure, connect the warning circuit, disconnect Q point automobile starting line.Diode D ₈, inductor G forms induction system.Automobile is promptly exported a signal voltage through D in 5 seconds when being subjected to the collision of any dynamics ₈Trigger warning circuit.Ic chip ₂, capacitor C ₃, potential device W ₂, resistance R ₆, relay J ₅Form the stable multi-oscillation circuit.After the beeper signal receives any one work of amplification latching circuit, timekeeping circuit or induction system, J ₃All closed and through normally closed contact J _3-1To oscillating circuit power supply, IC ₂Electric after, internal oscillator work, IC ₂3 pin outgoing levels are one high and one low, by changing between 0～12V, and pass through IC ₂The external relay J of 3 pin ₅Open contact J _5-1, J _5-2One closes one closes to the left and right indicator power supply of automobile, and its flash of light is warned, and flash rate can be by W ₂Regulate.Ic chip ₃, relay J ₆, J ₇, resistance R ₇, R ₈, annunciator SP forms the warning circuit.After the beeper signal receives amplification latching circuit, timekeeping circuit, any one work of induction system, J ₃Closure is passed through J _3-2Normally closed contact disconnects J ₇Power supply, J ₇Discharge, disconnect Q point automobile starting line respectively and connect annunciator SP.IC ₃The direct 12V of 2 pin power supply is when the circuit output line is cut off or complete machine when destroyed IC ₃2 pin dead electricity become low level by high level, IC ₃Conducting, J ₆Closure is passed through J _6-1Open contact cuts off J ₇Power supply makes J ₇Dead electricity discharges, and connects annunciator SP, disconnects Q point automobile starting line.MK is external door contact interrupter line, and the F point is external inductor line, and the C point is direct powered battery, LD ₁, LD ₂Be automobile steering lamp line, D ₁～D ₇Protection diode for relay.

Beeper (2) is selected used on the market beeper for use, is incorporated into the power networks with local paging station; After the car owner finds that vehicle is stolen, can call out the beeper number to paging station, after beeper receives signal, produce vibrations or ring tone, bring out the trigger-type annunciator at once and send alerting signal, and the work of command circuit controller, cut off vehicle startup system.

When vehicle meets when plundering travelling, the car owner can press can leave vehicle (auto timer pick up counting work) behind the auto timer, after reaching preset time, auto timer is then connected the trigger-type annunciator and is sent alerting signal, and the work of command circuit controller, cut off vehicle startup system.

The utlity model has following advantage: (one) can cut off vehicle startup system automatically when being in alarm condition. (2) phone length, can realize the whole province or nationwide warning by the beeper call signal, and make automobile stop at once travelling in the situation of the networking of beeper the whole province or national network apart from the control warning, sends alarm signal. (3) have the self-clocking effect, realize the automatic timed alarm function.
