Abstract
The utility model relates to a theft-proof alarming control device for an automobile, particularly a theft-proof alarming control device used on an automobile, a motor cycle and other motor vehicles, which is composed of a sensing circuit, an alarm circuit and a control circuit. The utility model is characterized in that the control circuit is constituted by connecting a pressure sensing element with a circuit switch in series. One end of the connected in series branch circuit is connected with the primary negative end of the ignition coil of a motor vehicle, and the other end is connected with the ground. The control end of the circuit is connected with the output of the switch or the output of the alarm circuit. The utility model firstly realizes controlling the ignition coil via a single wire, with an ideal effect.
Description
The utility model relates to a kind of anti-theft alarming control device, particularly used anti-theft alarming control device on the self-propelled vehicle such as automobile, motor bike.
Used anti-theft and alarm device generally is made up of sensor, warning circuit and control circuit on the self-propelled vehiclees such as existing automobile, motor bike, its control circuit adopts relay to be serially connected in the high-tension coil loop of self-propelled vehicle usually, but the normal ignition driving can't start self-propelled vehicle with regard to point of cutoff fire coil loop when relay contact disconnects when relay contact is connected.But when installing on the one hand, wants by this class anti-theft and alarm device breakdown point fire coil loop, require very high to relay on the other hand, its pitting of contact of long-term use is serious, even the relay that is of high quality, its contact switch number of times also has only about 50,000 times, influences the reliability and the service life of relay.What is more, also can make self-propelled vehicle flame-out suddenly when cruising because of the defective of relay, and its use is restricted.
The purpose of this utility model is exactly to provide a kind of reliable working performance in order to address the above problem, and long service life need not be destroyed the motor vehicle antitheft alarm controller in self-propelled vehicle high-tension coil loop.
Technical solution of the present utility model:
A kind of motor vehicle antitheft alarm controller, it is made up of sensing circuit (1), warning circuit (2) and control circuit (3), it is characterized in that control circuit (3) is made of pressure responsive device (4) and contactor (5) serial connection, this serial connection branch road one end is connected with the elementary negative terminal of self-propelled vehicle high-tension coil (6), other end ground connection, the control end of contactor (5) links to each other with the output of sensing circuit (1) or the output of warning circuit (2).
The utility model is first on the self-propelled vehicle high-tension coil and connection control circuit, to not doing any destruction and have no effect in the high-tension coil loop, realized single line control ignition coil, its control circuit adopts pressure responsive device and contactor to realize, working current reduces greatly, be the milliampere level, so overcome the pitting of contact defective of relay.The utility model line construction is simple, reliable working performance, and volume is little, long service life.
Fig. 1 is an electric theory structure scheme drawing of the present utility model.
As Fig. 1, sensing circuit of the present utility model (1) is to adopt conventional transducer, as mercury switch, and magnetic switch, infrared invasion probe, microwave invasion probe, the circuit of composition such as fine motion sensing probe.Warning circuit of the present utility model (2) adopts custom circuit, as the warning circuit of forming with buzzer phone, loudspeaker, music-integrating block or wireless launcher etc.The output of sensing circuit (1) can be controlled control circuit (3) by warning circuit (2), also can directly control warning circuit (2) and control circuit (3) simultaneously.Pressure responsive device (4) in the control circuit (3) can adopt pizo-resistance, also can adopt the bi-directional voltage stabilizing diode.Contactor (5) in the control circuit (3) can adopt relay, also can adopt other any type of switch or switch circuit, as transistor switching circuit, can turn-off bi-directional thyristor switch circuit or the like.If contactor (5) adopts relay, its control coil links to each other with the output of sensing circuit (1) or the output of warning circuit (2), and its contact is serially connected on the branch road of pressure responsive device (4).
The utility model is when the self-propelled vehicle cruising, ignition lock (8) is connected, contactor (5) in control circuit this moment (3) is in off-state, then the high-tension coil (6) of self-propelled vehicle and the work of cutout relay (or firing unit) (7) is not produced any influence.When self-propelled vehicle is in anti-theft state, as long as sensing circuit (1) has anti-theft signal output, then it makes warning circuit (2) send alerting signal on the one hand, inform that owner has abnormal condition, the control end of control circuit switch (5) makes contactor (5) become conducting state on the other hand, the ignition signal of high-tension coil (6) and cutout relay (or firing unit) (7) generation is at this moment suppressed by pressure responsive device (4), make the high-voltage output end Vo of high-tension coil (6) can't export high-voltage ignition signal, prevent the stolen purpose of being robbed of self-propelled vehicle thereby reach.
Claims (3)
1, a kind of motor vehicle antitheft alarm controller, it is made up of sensing circuit (1), warning circuit (2) and control circuit (3), it is characterized in that control circuit (3) is made of pressure responsive device (4) and contactor (5) serial connection, this serial connection branch road one end is connected with the elementary negative terminal of self-propelled vehicle high-tension coil (6), other end ground connection, the control end of contactor (5) links to each other with the output of sensing circuit (1) or the output of warning circuit (2).
2, by the described motor vehicle antitheft alarm controller of claim 1, it is characterized in that pressure responsive device (4) can adopt pizo-resistance, also can adopt the bi-directional voltage stabilizing diode.
3, by the described motor vehicle antitheft alarm controller of claim 2, it is characterized in that contactor (5) preferably adopts relay, its control coil links to each other with the output of sensing circuit (1) or the output of warning circuit (2), and its contact is serially connected on the branch road of pressure responsive device (4).
