Abstract

The electrical has a resistor and a capacitor coupled to the battery and with a switching transistor and signal generator. The switch is mounted on the steering wheel of the road vehicle and so long has it is held down the signal generator does not provide an output. If released the generator activates a buzzer.

Description

Bekanntlich tritt immer häufiger der sogenannte „Sekundenschlaf" bei vielen Autofahrern auf, was zu schlimmen Unfällen führen kann. Vor allem ist dies bei Autobussen der Fall, wo viele Leute transportiert werden. Um diesen Umstand zu verhindern, dient der Schutrgegenstand, der wie folgt beschrieben wird.As is well known, the so-called "second sleep" for many drivers on what bad accidents to lead can. Especially this is the case with buses, where a lot of people be transported. To prevent this, the Protective object, which is described as follows.

Über den Ladewiderstand(LW) wird der Kondensator(LK) nach einer e-Funktion aufgeladen. Bei Erreichen einer Spannung von ca. 5V wird der Ausgang des Verstärkers A von + 12 V auf 0 V und der nachgeschaltete Verstärker B von 0 V auf + 12 V umgeschalten. Dadurch wird der Transistor T1 durchgeschaltet und der Signalgeber (SG) wird über den Kondensator K1 und den parallelen Entladewiderstand(EW) aktiviert. Dadurch gibt der Signalgeber (SG) ein kurzes Signal ab. Der Spannungsteiler(ST) liefert die erforderlichen Schaltspannungen für die Verstärker.about the charging resistance (LW) becomes the capacitor (LK) after an e-function charged. When a voltage of approx. 5V is reached, the output of the amplifier A from + 12 V to 0 V and the downstream amplifier B from Switched 0 V to + 12 V. As a result, the transistor T1 is turned on and the signal generator (SG) is over the capacitor K1 and the parallel discharge resistor (EW) activated. As a result, the signal generator (SG) emits a short signal. The voltage divider (ST) delivers the required switching voltages for the amplifiers.

Drückt der Fahrer den Drucktaster, wird der Kondensator (LK) und der Kondensator K1 entladen und der Vorgang wie unter 2. beschrieben wiederholt sich.If the driver presses the push button, the capacitor (LK) and the capacitor K1 are discharged and the The process as described under 2. is repeated.

Drückt der Fahrer aber den Taster(DT) nicht, so steigt die Kondensatorspannung(LK) weiter bis 6,5 V und damit wird der Ausgang des Verstärkers C von +12 V auf 0 V und der Ausgang des nachgeschalteten Verstärkers D von 0 V auf +12 V umgeschaltet. Dadurch wird der Transistor T2 durchlässig und schaltet den Signalgeber auf volle Lautstärke ein.If the driver presses the button (DT) not, the capacitor voltage (LK) continues to rise to 6.5 V and this will be the output of the amplifier C from +12 V to 0 V and the output of the downstream amplifier D switched from 0 V to +12 V. This makes transistor T2 transparent and switches the signal generator to full volume.

Die Einrichtung kann sowohl als getrennte Schaltung aufgebaut sein, als auch im Armaturenbrett und am Lenkrad eines Fahrzeugs integriert werden. Der Drucktaster kann über Kabel oder direkt am Lenkrad montiert sein.The device can be used as a separate circuit be built, as well as in the dashboard and on the steering wheel Vehicle can be integrated. The push button can be wired or mounted directly on the steering wheel.

Parallel zu dem Signalgeber kann auch ein Relais eingeschaltet sein, dessen Hilfskontakte die Zündung des Fahrzeugs unterbrechen und damit den Motor ausschalten.In parallel to the signal generator a relay must also be switched on, the auxiliary contacts for the ignition of the Interrupt the vehicle and switch off the engine.
