Abstract
The utility model relates to an alarm sounding controller for automobiles, which is composed of a 555 timer chip, a relay, a resistor and a capacitor; two signal input ends of the 555 chip are respectively connected with the automobile ceiling lamp door control switch and an output end of an automobile anti-theft apparatus; the signal output ends of the 555 chip are connected with the coils of the relay; one end of a key point of the relay is connected with the automobile anti-theft apparatus, and the other end is connected with an automobile horn. When other people pry off the door, the relay is attracted to fold and the automobile horn sends out alarm. The utility model can control false alarm sounding of an anti-theft apparatus generated by automobile vibration of various causes; the utility model has the simple structure and low cost, which can be directly matched with the existing automobile anti-theft apparatus.
Description
The utility model relates to a kind of alarming device for automobile anti-theft, particularly about a kind of control setup of the automobile anti-theft alarm sound.
At present, the principle of work of the car alarm that people generally use is: in case vibrations appear in vehicle, Car Burglar Alarm just begins to report to the police, the warning car light flicker of automobile, and loudspeaker are screamed.The shortcoming of this Car Burglar Alarm is: bumped automobile because of carelessness as the people, Car Burglar Alarm is with regard to flase alarm, and horn trumpet utters a scream.What is more, bad when weather, when thundering, because vibration also makes the Car Burglar Alarm flase alarm, forms noise emission, influences other people and work, have a rest.
The purpose of this utility model is a kind of controller of design, and the Control of Automobile alarm sound has only when other people pry open car door, and horn trumpet just sends the sound, the sound that sends when preventing the car alarm flase alarm.
For achieving the above object, the technical solution of the utility model is: this auto alarm sound controller, by 555 timer chips, relay constitutes, first signal input part of 555 timer chips links to each other with automobile ceiling light door contact by first resistance, the secondary signal input end links to each other with the car alarm mouth by second resistance, and signal output part links to each other with relay coil by the 3rd resistance; End battle one of relay links to each other with the Car Burglar Alarm mouth, and the other end links to each other with horn trumpet.
The utility model and existing car alarm are used, and do not need existing car alarm is done any transformation.The utility model utilizes 555 timer chips to form flip-flop multivibrator, and the conducting of control relay utilizes Control of Automobile loudspeaker battle of relay, thereby prevents the sound that the Car Burglar Alarm flase alarm sends.The utility model is simple in structure, and cost is low, overcomes existing car alarm shortcoming, reaches the standard and the function of Ministry of Public Security's eco-friendly car Car Burglar Alarm, makes the effect of existing car alarm more satisfactory.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model auto alarm sound controller circuitry figure.
As shown in Figure 1, the utility model is by 555 timer chip U1, and relay J and resistance capacitance constitute.2. the signal input part of U1 passes through resistance R
1K1 links to each other with automobile ceiling light door contact, and 6. the signal input part of U1 passes through resistance R
2U2out links to each other with the car alarm mouth, and 3. the signal output part of U1 passes through resistance R
3Link to each other with the coil of 12V relay J; Relay J battle JK an end link to each other with the mouth of Car Burglar Alarm U2, the other end links to each other with horn trumpet Y.
When the driver leaves automobile, with remote controller automobile is set up defences behind the lock car, the signal input part of 555 chips is the input pulse signal 6., if car is stolen in other people attempt, in the moment of prying open car door, automobile ceiling light door contact is connected, and 2. the signal input part of 555 chips becomes low level by high level, and 3. the signal output part of 555 chips becomes high level by low level, the relay J coil gets, JK closure battle of relay J, horn trumpet begin to report to the police, the flicker of warning car light.When other people have bumped automobile or because of carelessness because vibration when making the Car Burglar Alarm flase alarm, because the ceiling light door contact is not connected, 2. the input end of 555 chips still is level"1", and 3. the mouth of 555 chips still is level "0", and the relay J coil must not, battle, JK was not closed, at this moment, four warning car lights that have only automobile are in flicker, and the loudspeaker of automobile do not send the sound, thereby reach the Control of Automobile alarm sound, prevent the purpose of car alarm flase alarm.
Claims (2)
1, a kind of auto alarm sound controller, by 555 timer chips, relay constitutes, and it is characterized in that:
First signal input part of described 555 timer chips (U1) is by the first resistance (R
1) link to each other with automobile ceiling light door contact (K1), the secondary signal input end is by the second resistance (R
