Abstract

The system consists in that the car radio, without the safety box which is in the hands of the user, transforms itself into a transmitter when it is removed. In this way, the car radio transmits a signal when it is used after a theft, which signal is received by the police and will lead to locating and apprehending the thieves. As a result, thefts of car radios will be a matter of the past.

Description

Das Autoradio wird so hergestellt, daß der HF-Ant. Verstärker, ein Mini-Sender, einen Micro-Relaise (Öffner), der dem Relais-Spule parallel geschaltetem Transistor, wird durch einem Zähler/Decoder Kombination in einem geschlossenen, integriertem Modul ausgeschaltet (Skizze 2a, b, c, d, e).The car radio is manufactured so that the HF-Ant. Amplifier, a mini transmitter, a micro-relay (break contact), the transistor connected in parallel with the relay coil, is combined by a counter / decoder combination closed, integrated module switched off (Sketch 2a, b, c, d, e).

Bei einem möglichem Diebstahl wird die Dauerspannung unterbrochen. Das Öffner-Relais schließt die Kontakte weil der Strom in der Magnetspule unterbrochen wird. Dadurch kommt der Mini-Sender (Skizze 2.b) in Bereitschaft für eine Betriebsspannung (+12 V). Beim Anschluß an diesem entnimmt der Transistor der paral­ lel zur Relais geschaltet ist (Skizze 2.c, d) über geschlossenen Kontakte (+) deren Basis zusätzlich ist die Spannung und bildet durch Leitung der Spannung eine Brücke über die Relais-Spule, so daß der Relais aus­ geschaltet ist und dessen Kontakte geschlossen bleiben. Bei Inbetriebnahme des Gerätes beginnt der Mini-Sender Signale zu geben, so daß diese empfangen werden und das Gerät geortet werden kann.In the event of a possible theft, the permanent voltage interrupted. The normally closed relay closes the contacts because the current in the solenoid is interrupted. This brings the mini transmitter (sketch 2.b) in Ready for an operating voltage (+12 V). At the The transistor is connected to the paral lel switched to the relay (sketch 2.c, d) over closed contacts (+) whose base is additional the tension and forms a by conducting the tension Bridge over the relay coil so that the relay is off is switched on and its contacts remain closed. The mini transmitter starts when the device is started up To give signals so that they are received and the device can be located.

Wenn der Besitzer das Autoradio ausmontieren will, steckt dieser einen Chip (xy) (Skizze 1 und Skizze 2 - xy -) der ein Zubehör des Radios ist, in den vorgesehenen Schlitz und trennt das Gerät von der Spannung.If the owner wants to remove the car radio, he puts a chip (xy) (sketch 1 and sketch 2 - xy -), which is an accessory of the radio, in the slot provided and disconnects the device from the voltage.

Das im Chip befindliche Frequenzgenerator ist bereits im Frequenz codiert. Beim Anschluß des Gerätes an Spannung, leitet das (x) Integrier-Modul dem Zähler/ Decoder (Skizze 2.e) diesen, und im Ausgang des Zähler/Decoders entsteht ein (-) Low-Signal.The frequency generator in the chip is already coded in frequency. When the device is connected to voltage, the (x) integration module directs the counter / decoder (sketch 2.e), and a (-) low signal is generated in the output of the counter / decoder.

Dieses (-) Low-Signal macht den Basis (-) des Tran­ sistors (Skizze 1.f) der den Relais sperrt, und dadurch funktioniert der Relais und öffnet die Kon­ takte so, daß der Mini-Sender keine notwendige Betriebsspannung erhält.This (-) low signal makes the base (-) of the tran sistors (sketch 1.f) which blocks the relay, and this will make the relay work and open the con clock so that the mini transmitter no necessary Receives operating voltage.

Claims (3)

Die bisherigen diebstahlsicheren Autoradios beruhen auf dem System, daß diese vom Dieb nicht benutzt werden können, dadurch, daß der Besitzer einen Kod-Nr. hat, oder das Suchlauf-System abmontierbar ist.The previous anti-theft car radios are based on the system that the thief is not using it can be, that the owner a Code no. or the search system can be removed is. Trotzdem werden die Systeme durch Diebe übergangen, indem entweder, die Kod. Nr. ausfindig gemacht wird, oder durch eine Extraspannung das Gerät in Betrieb genommen wird, und auch weil nur die Cassettenteile ausreichen erscheint.Still, the systems are overruled by thieves by either locating code no. or the device in operation due to an extra voltage is taken, and also because only the cassette parts appears sufficient. Beim 100% Safe System dagegen ist die Benutzung des Diebesgutes unmöglich, weil dadurch das Gerät selbst einen Signal sendet und der Polizei die Ortung des gestohlenen Gerätes möglich macht.With the 100% Safe System, however, the use of the Theft is impossible because it makes the device itself sends a signal and the police locate the stolen device.
