Abstract
Description
Autodiebstahlsicherung Die Erfindung bezieht sich auf eine neuartige, elektronische Autodiebstahisicherung, die gegenüber allen bekannten Sicherungen für diesen Zweck den Vorteil hat, allen Gegebenheiten in der Praxis gerecht zu werden.Car theft protection The invention relates to a novel, Electronic anti-theft device, which is different from all known fuses for this purpose has the advantage of being able to do justice to all conditions in practice.
Wird das Gerät mittels des im Wageninneren versteckt angeordneten Ein/Ausschalters in Betrieb gesetzt, hat der Fahrer noch genügend Zeit, den Fahrgastraum zu verlassen und ihn zu verschließen, ohne daß der Alarm schon ausgelöst wird. Nach Ablauf der Verzögerung von ca. fünf Sekunden ist das Gerät so in Bereitschaft geschaltet, daß es Manipulationen an den Schlössern und das Öffnen derselben registriert, um dann wiederum nach fünf Sekunden den Alarm auszulösen. Diese Verzögerung dient auch wiederum dem Zweck, daß der befugte Fahrer in die Lage versetst wird, die Tür zu öffnen, einzusteigen, die Türe zu schließen und die Diebstahlsicherung wieder auszuschalten. Da im Gegensatz hierzu ein Unbefugter den Alarm in dieser Zeit nicht ausschalten kann, weil er nicht weiß, wo der Schalter angeordnet ist, wird der Alarm ausgelöst und folgendes bewirkt s Die Hupe ertönt auf die Dauer son 10 Sekunden, anschließend leuchten die abgeblendeten Scheinwerfer auf, danach ertönt die Hupe nochmals für 3 Sekunden und dann folgt ein laufendes Blinken der Scheinwerfer unterbrochen von dem abwechselnden Hupen in Zeitabständen von Jeweils 3 Sekunden.If the device is hidden inside the car by means of the With the on / off switch activated, the driver still has enough time to access the passenger compartment to leave and lock it without triggering the alarm. To After the delay of approx. Five seconds has elapsed, the device is switched to standby, that it registers tampering with the locks and the opening of the same then trigger the alarm again after five seconds. This delay also serves again for the purpose of enabling the authorized driver to close the door Open, get in, close the door and switch off the anti-theft device again. In contrast to this, an unauthorized person will not switch off the alarm during this time because he does not know where the switch is located, the alarm is triggered and the following has the following effect s The horn sounds for 10 seconds, then light up the dimmed headlights on, then the horn sounds again for 3 seconds and then a continuous flashing of the headlights is interrupted by the alternating horns at intervals of 3 seconds each.
Beim Einschalten des Gerätes wird der Kondensator C1 auf ungefähr 2,1 V gegen Masse aufgeladen. Dieser Vorgang dauert ca. 5 Sekunden. Durch die Inversion wird es dem Eingange-Gate und der Flip-Flop-Schaltung ( FF ) ermöglict, auf Eingangsimpulse anzusprechen. Wird nun einer der vier Eingang ( 4 - g4 ) erregt, so wird diese Kippstufe angestoßen und verweilt ca. 5 Sekunden im metastabilen Zustand.When the device is switched on, the capacitor C1 becomes approximately 2.1 V charged to ground. This process takes about 5 seconds. By inversion it enables the input gate and the flip-flop circuit (FF) to respond to input pulses to address. If one of the four inputs (4 - g4) is now excited, this flip-flop is activated triggered and remains in the metastable state for about 5 seconds.
Nach Ablauf dieser Verzögerung kippt die zweite Stufe in ihren instabilen Zustand und lost über das Relais Rt ein Hubsigaal aus. Die Verzögerungszeit dieser Stufe beträgt ca. 7 Sekunden. Nach Ablauf dieser Zeit wird die Flip-Flop-Schaltung erregt, wodurch die Plusleitung zu den abgeblendeten Scheinwerfern unterbrochen wird.; gleichzeitig läuft der Generator an, der mit einer Frequenz von 0,33 Hz alle drei Sekunden die Hupe über das Relais R1' und die Scheinwerfer über das Relais R3 ein- und ausschaltet.After this delay has elapsed, the second stage flips into its unstable state State and triggers a Hubsigaal via the relay Rt. The delay time of this Level is approx. 7 seconds. After this time has elapsed, the flip-flop circuit energized, which interrupted the positive lead to the dimmed headlights will.; at the same time the generator starts up, with a frequency of 0.33 Hz all three seconds the horn via the relay R1 'and the headlights via the relay R3 turns on and off.
In der Zeichnung ist das Schaltungsschema dargestellt.The circuit diagram is shown in the drawing.
