Abstract
The utility model relates to a vehicle anti-theft device, which comprises a control circuit and an alarm circuit. The control circuit is a closed circuit composed of serially connected a vehicle power supply, a controlled silicon and a relay coil, wherein, the control electrode of the controlled silicon is connected with the anode of the power supply through a magnetic sensor; the alarm circuit is also a closed circuit composed of serially connected the vehicle power supply, a normally closed switch of the relay, an alarm trigger controlled silicon and an alarm, wherein, the control electrode of the alarm trigger controlled silicon is connected with the anode of the power supply through an alarm sensor switch; the high-voltage ignition line of the vehicle is serially connected with a normally open switch of the relay. The utility model is of simple structure and lower cost; if the anti-theft alarm is not released, the high-voltage ignition line of the vehicle will always remain disconnected, and therefore, the vehicle can not be start all the time with a good anti-theft effect.
Description
Technical field
The utility model relates to a kind of alarms and security systems for automobiles.
Background technology
Alarms and security systems for automobiles is mostly realized automobile burglar for the pick-proof of door body at present, and effect is very undesirable in the reality; And other is to the anti-joyride device complex structure mostly of igniting, and manufacturing cost is higher, and inconvenience is applied.
The utility model content
The utility model purpose is to provide a kind of alarms and security systems for automobiles simple in structure, lower-cost.
To achieve these goals, the utility model adopts following technical scheme: alarms and security systems for automobiles, it comprises control circuit and warning circuit, described control circuit is composed in series close circuit successively by automobile power source, silicon control, relay coil, and the silicon controlled control utmost point is connected with positive source by a magneto-dependent sensor switch; Described warning circuit is composed in series close circuit by automobile power source, relay normally closed switch, the triggering of reporting to the police successively with silicon control, annunciator, reports to the police to trigger with the silicon controlled control utmost point to be connected with positive source by the warning sensor switch; Be in series with the relay normally open switch on the high-voltage ignition for automobile line.
The anodal connection of automobile power source unilateral diode is in parallel with the additional supply that is provided with together then in the described warning circuit, inserts warning circuit again.
Described annunciator two ends also are parallel with the radio alarming feedway.
Also be provided with on and off switch in the described control circuit.
The utility model is simple in structure, and cost is lower, if do not remove antitheftly, the high-pressure ignition wire of automobile disconnects all the time, and automobile can not start all the time, and anti-theft effect is better.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
The specific embodiment
Alarms and security systems for automobiles as shown in Figure 1, it comprises control circuit and warning circuit, and described control circuit is composed in series close circuit successively by automobile power source, silicon control MCR1, relay coil J, and the relay J two ends are parallel with diode D1; The control utmost point of silicon control MCR1 is connected with positive source by a magneto-dependent sensor switch G1; Described warning circuit is composed in series close circuit by automobile power source, relay normally closed switch CD, the triggering of reporting to the police successively with silicon control MCR2, annunciator P, and the control utmost point that triggers with silicon control MCR2 of reporting to the police is connected with positive source by warning sensor switch G2; Be in series with relay normally open switch AB on the high-voltage ignition for automobile line.The anodal connection of automobile power source unilateral diode D2 is in parallel with the additional supply that is provided with together then in the warning circuit, inserts warning circuit again.Annunciator P two ends also are parallel with radio alarming feedway Q, can send signal to when reporting to the police on the hand-held warning receiving device.Also be provided with on and off switch K in the control circuit.Whether warning sensor switch G2 can be arranged on wheel or the bearing circle, be used for monitoring car and move.
After opening car door, must be with magnet near the position that magneto-dependent sensor switch G1 is set, G1 is because of being subjected to the magnetic force conducting, silicon control MCR1 is because of obtaining the energizing signal conducting, relay coil J gets electric, relay normally open switch AB closure, and relay normally closed switch CD opens the releasing warning circuit.If magnet of no use is near the position that magneto-dependent sensor switch G1 is set, and when automobile being moved with additive method, warning sensor switch G2 will receive signal and closure, report to the police and trigger the conducting with silicon control MCR2, and warning circuit powers alarm concurrent feed signals to hand-held annunciator.
After K switch disconnects, when warning waits work and gets, if vehicle power is destroyed, do not influence warning, because be added with additional supply in the warning circuit yet.
Claims (4)
