Abstract
Description
Die Erfindung betrifft ein Einsatzgerät integriert mit Autoradios zur Speicherung und zum Empfang von Verkehrs durchsagen.The invention relates to an insert device integrated with Car radios for storing and receiving traffic announce.
Die Idee befaßt sich speziell mit dem Problem des Ver kehrsfunkservice bei Autoradios. Die Rundfunkanstalten bieten dem Autofahrer die Informationsdienstleistung des Verkehrsfunk an, welches zu bestimmten Uhrzeitpunk ten gesendet wird. Ist nun ein Autofahrer mit einem ver kehrsfunktauglichen Empfangsgerät ausgestattet, so kann er nur zu bestimmten Zeitpunkten die Informationsdienst leistung der Rundfunkanstalten in Anspruch nehmen. Dies soll nun durch die Erfindung verbessert werden, in dem die Autoradios mit einem Einsatzgerät ausgerüstet werden, um den Verkehrsfunk zu jeder Zeit empfangen zu können. Auf diese Weise erhält der Autofahrer die Mög lichkeit, jederzeit eine aktuelle Verkehrslagendurchsage aus eigenem Radio abzurufen, die es ihm ermöglicht, seine Fahrstrecke, der Durchsage entsprechend zu ändern. Die Verwirklichung dieser Erfindung kann auch dazu bei tragen, daß viele Autofahrer aufgrund ihrer Informationen gar nicht erst in einen Stau hineinfahren würden, son dern auf eine Umleitung ausweichten, was mögliche Unfälle am Stauende reduzieren oder die Staulänge auf ein Minium beschränken könnte. Diese Möglichkeit ist nun durch das erfindungsgemäße Einsatzgerät geschaffen worden.The idea deals specifically with the problem of ver Kehrsfunk service at car radios. The broadcasters offer the information service to the driver of the traffic radio, which at a certain time ten is sent. Is now a driver with a ver equipped radio receiver, so can he only the information service at certain times use the services of the broadcasters. This is now to be improved by the invention in which the car radios are equipped with an insert device to receive the traffic information at any time can. In this way, the driver gets the opportunity a current traffic situation announcement at all times retrieve from his own radio, which allows him his Route to change according to the announcement. The implementation of this invention can also help that many motorists carry based on their information wouldn't even get into a traffic jam, son change to a diversion, what possible accidents at the end of the traffic jam or reduce the traffic jam length to a minimum could restrict. This possibility is now through the Insert device according to the invention has been created.
Der Sendevorgang ist wie bisher.The sending process is as before.
Der Rundfunksender sendet das Verkehrsfunksignal aus, das die empfangsfähigen Autoradiogeräte empfangen können. Das verkehrsfunktaugliche Autoradiogerät empfängt das Verkehrs funksignal und unterbricht das im Augenblick laufende Pro gramm, sei es Radio oder Kassette. Bei den bekannten Ge räten erfolgt nun die Verkehrsdurchsage.The radio broadcaster broadcasts the traffic signal that the receivable car radio can receive. The Traffic radio-compatible car radio receives traffic radio signal and interrupts the currently running pro grams, be it radio or cassette. With the known Ge the traffic announcement is now carried out.
Durch die Erfindung und das Einsatzgerät für Autoradios wird nun dieser Vorgang geändert, um den Service für den Autofahrer zu erweitern. Wie bisher empfängt ein verkehrs funktaugliches Empfangsgerät das von den Rundfunkanstal ten ausgesandte Signal. Das Signal bewirkt nun, daß ein vorgesehener programmierter Chip aktiviert wird. Im Chip löst das Signal folgenden programmierten Vorgang aus (in der graph. Darstellung nicht enthalten). Die in digitaler Form gespeicherte Verkehrsdurchsage soll gelöscht werden. Im Anschluß daran fragt der Chip den vorgesehenen Digital- Analog-Wandler nach neuen Daten ab, die er abspeichern soll. Ist die Abfrage beendet, so wartet der Chip ein Sig nal ab, das das Verkehrsdurchsageende kennzeichnet. Wird der Empang dieses Signals vom Chip registriert, so wird der Aufnahmevorgang abgeschlossen. Eine Abruftaste am Radio, von einem Relais gesteuert, ermöglicht, daß die im Chip abgezeichnete Verkehrsdurchsage an den Digital- Analog-Wandler geleitet wird. Der Digital-Analog-Wandler seinerseits verarbeitet die Daten und leitet diese an ei nen vorgesehenen elektromagnetischen Schwingkreis, der durch Demodulation die Verkehrsdurchsage wieder hörbar macht.By the invention and the application device for car radios this process is now changed to the service for the Expand motorists. As before, traffic receives radio-compatible receiving device from the broadcaster emitted signal. The signal now causes a provided programmed chip is activated. On chip the signal triggers the following programmed process (in the graph. Representation not included). The one in digital Formed traffic announcement should be deleted. The chip then asks the intended digital Analog converter for new data, which it store should. When the query is finished, the chip waits for a sig that indicates the end of the traffic announcement. Becomes the receipt of this signal by the chip is registered the recording process is completed. A call button on Radio, controlled by a relay, allows the Traffic announcement signed on the chip to the digital Analog converter is routed. The digital-to-analog converter in turn processes the data and forwards it to egg NEN provided electromagnetic resonant circuit, the the traffic announcement can be heard again by demodulation makes.

Ausgehend vom Sendebereich der Sendeanstalten empfängt das Autoradiogerät das Signal der Verkehrsdurchsage. Die ses Signal bewirkt nun, daß der programmierte Chip 5 ak tiviert wird. Im Chip 5 löst das Signal folgenden pro grammierten Vorgang aus (in der Darstellung Fig. 3 nicht enthalten). Die in digitaler Form gespeicherte Verkehrs durchsage soll gelöscht werden. Im Anschluß daran fragt der Chip 5 den Digital-Analog-Wandler 6 nach neuen Daten ab, die er abspeichern soll. Ist die Abfrage beendet, so wartet der Chip 5 ein Signal ab, das das Verkehrsdurch sageende kennzeichnet. Wird der Empfang dieses Zeichens vom Chip registriert, so wird der Aufnahmevorgang abge schlossen. Eine Abruftaste 8 am Radio ermöglicht nun, von einem Relais 7 gesteuert, daß die im Chip abgezeich nete Verkehrsdurchsage an den Digital-Analog-Wandler 6 geleitet wird. Der Digital-Analog-Wandler 6 seinerseits verarbeitet die Daten und leitet diese an den elektro magnetischen Schwingkreis 3, der durch Demodulation die Verkehrsdurchsage wieder hörbar macht.Starting from the broadcasting area of the broadcasters, the car radio receives the signal of the traffic announcement. This signal now causes the programmed chip 5 to be activated. In chip 5 , the signal triggers the following programmed process (not included in the illustration in FIG. 3). The traffic announcement saved in digital form is to be deleted. The chip 5 then queries the digital-to-analog converter 6 for new data which it is to save. If the query is ended, the chip 5 waits for a signal which indicates the end of the traffic announcement. If the receipt of this character is registered by the chip, the recording process is completed. A call button 8 on the radio now enables, controlled by a relay 7 , that the traffic announcement marked in the chip is passed to the digital-to-analog converter 6 . The digital-to-analog converter 6 in turn processes the data and passes it to the electro-magnetic resonant circuit 3 , which makes the traffic announcement audible again by demodulation.
Auf diese Weise erhält der Autofahrer die Möglichkeit, zu jedem Zeitpunkt, außer während des Speichervorgangs eine aktuelle Verkehrsdurchsage aus eigenem Radio abzu rufen, die es ihm ermöglicht, seine Fahrstrecke der Durchsage entsprechend zu planen.In this way, the driver has the opportunity at any time, except while saving to make a current traffic announcement from their own radio call that allows him to track his route of travel Plan the announcement accordingly.
