Abstract

Es wird ein Empfänger zum Empfang von Rundfunksendungen vorgeschla­gen, der eine Auswerteschaltung für digital übertragene Verkehrs­nachrichten besitzt. Der Rundfunkempfänger weist einen Speicher auf, in dem straßenorientierte Segmente vorgesehen sind, die in Strecken­segmente untergliedert sind. Beim Empfang von digitalen Verkehrs­nachrichten ist es hinreichend, die Straße, das Streckensegment und die Richtung anzugeben. Aufgrund der im Speicher aufgeführten Anord­nung ist es dann für den Empfänger möglich, sich die weiteren Infor­mationen zu generieren. Dadurch wird erreicht, daß die digitale Da­tenübertragung mit einer schnellen Wiederholungsrate erfolgen kann.

A receiver for receiving radio broadcasts is proposed, which has an evaluation circuit for digitally transmitted traffic messages. The radio receiver has a memory in which street-oriented segments are provided, which are subdivided into line segments. When receiving digital traffic messages, it is sufficient to specify the street, the route segment and the direction. Because of the arrangement listed in the memory, it is then possible for the receiver to generate the further information. It is thereby achieved that the digital data transmission can take place at a fast repetition rate.

Description

Stand der TechnikState of the art

Aus der Zeitschrift Bosch Technische Berichte, Band 8 (1986), Heft 1/2, Seiten 15 bis 25 ist es bekannt, codierte Verkehrshinweise über UKW-Rundfunksender mittels RDS zu übertragen. Gemäß den dort gemach­ten Vorschlägen, sind die Verkehrshinweise typisiert, so daß nicht die gesamte Verkehrsinformation übertragen werden muß, sondern es genügt, lediglich Schlüsselworte zu übertragen. Durch das dort vor­geschlagene Übertragungsverfahren wird erreicht, daß ein Empfänger nach dem Empfang von drei Gruppen in der Lage ist, eine Verkehrs­information auszugeben. Der dort vorgeschlagene Weg hat sich be­währt, es hat sich jedoch gezeigt, daß insbesondere bei einer Viel­zahl von zu übertragenden Informationen es recht lange dauert, bis alle Informationen über Verkehrsstörungen zum Empfänger übertragen worden sind.From the magazine Bosch Technischeberichte, Volume 8 (1986), Issue 1/2, pages 15 to 25, it is known to transmit coded traffic information via VHF radio stations using RDS. According to the suggestions made there, the traffic information is typed so that not all of the traffic information has to be transmitted, but it is sufficient to only transmit keywords. The transmission method proposed there ensures that a receiver, after receiving three groups, is able to output traffic information. The route proposed there has proven itself, but it has been shown that, especially with a large amount of information to be transmitted, it takes quite a long time for all information about traffic disturbances to be transmitted to the recipient.

Vorteile der ErfindungAdvantages of the invention

Bei der erfindungsgemäßen Ausgestaltung des Rundfunkempfängers gemäß den kennzeichnenden Merkmalen des Hauptanspruchs ergibt sich demge­genüber der Vorteil, daß die Datenübertragung zum Empfänger wesent­lich schneller durchführbar ist, so daß innerhalb der gleichen Zeit wesentlich mehr Informationen übertragbar sind. Der Betreiber des Empfängers ist daher in der Lage, wesentlich früher in den Be­sitz der Verkehrsnachrichten zu gelangen. Als weiterer Vorteil ist anzusehen, daß durch die vorgeschlagene Maßnahme die Redundanz der Übertragung erhöhbar und somit die gesamte Übertragung sicherer aus­zugestalten ist. Als weiterer Vorteil ist anzusehen, daß durch die vorgeschlagene Maßnahme konstenintensive Zusatzeinrichtungen nicht nötig werden.In the embodiment of the radio receiver according to the invention according to the characterizing features of the main claim, there is the advantage that the data transmission to the receiver can be carried out much faster, so that within the same Time much more information is transferable. The operator of the receiver is therefore able to get the traffic news much earlier. A further advantage is that the redundancy of the transmission can be increased by the proposed measure and the entire transmission can thus be made more secure. Another advantage is that the proposed measure does not require cost-intensive additional devices.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vor­teilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Empfängers möglich. Besonders vorteilhaft ist es, durch die zusätzliche Übertragung der Zahl der interessierten Strecken­segmente sicherzustellen, daß die Information sich nicht lediglich auf ein Steckensegment bezieht, sondern auch mehrere Streckenseg­mente umfaßbar sind. Dadurch wird die Flexibilität bei dem vorge­schlagenen Empfänger weiter erhöht.Advantageous further developments and improvements of the receiver specified in the main claim are possible through the measures listed in the subclaims. It is particularly advantageous to ensure by the additional transmission of the number of interested segment segments that the information relates not only to one segment of the plug, but also that several segment segments can be included. This further increases the flexibility of the proposed recipient.

Es zeigen Figur 1 ein Beispiel eines Empfängers zum Empfang von Rund­funksendungen mit überlagerter Verkehrsinformation und Figur 2 ein Ausführungsbeispiel des Aufbaus des im Empfänger enthaltenen Spei­chers.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. FIG. 1 shows an example of a receiver for receiving radio broadcasts with superimposed traffic information, and FIG. 2 shows an embodiment of the structure of the memory contained in the receiver.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Aus der Zeitschrift Bosch Technische Berichte, Band 8, 1986, Heft 1/2, Seiten 15 bis 25 ist es bekannt, Empfänger zum Empfang von Rundfunksendungen dadurch zu erweitern, daß auch digitale Verkehrs­informationen empfangbar sind. Hierzu wird das von den Rundfunk­anstalten diskutierte Radio-Data-System benutzt. Hierbei wird die Verkehrsinformation digital codiert, wobei es durch eine vorgegebene Typisierung möglich ist, eine verkehrsrelevante Meldung nahezu un­eingeschränkt auszugestalten. Die Auswertung der typisierten Über­tragung erfolgt hierbei im Empfänger.From the magazine Bosch Technical Reports, Volume 8, 1986, Issue 1/2, pages 15 to 25 it is known to receive receivers To expand radio broadcasts in that digital traffic information can also be received. The radio data system discussed by the broadcasters is used for this. In this case, the traffic information is digitally coded, it being possible, by means of a predetermined typing, to design a traffic-relevant message almost without restriction. The evaluation of the typed transmission takes place in the receiver.

Wie die Figur 1 zeigt, weist ein solcher Empfänger in bekannter Wei­se eine Antenne 10 auf, dem ein Hochfrequenz- und Zwischenfrequenz­teil 11 folgt. Dem Hochfrequenz- und Zwischenfrequenzteil 11 folgt ein Demodulator und Niederfrequenzverstärker 12, an den ein Laut­sprecher 16 angeschlossen ist.As FIG. 1 shows, such a receiver has an antenna 10 in a known manner, which is followed by a high-frequency and intermediate-frequency part 11. The high-frequency and intermediate-frequency part 11 is followed by a demodulator and low-frequency amplifier 12, to which a loudspeaker 16 is connected.

Weiterhin ist an den Hoch- und Zwischenfrequenzteil 11 ein RDS-Emp­fänger 13 angeschlossen, wie er beispielsweise aus der vorgenannten Druckschrift bekannt ist. Dieser RDS-Empfänger wirkt auf einen Spei­cher 14 ein, an den seinerseits eine Ausgabeeinheit 15 angeschlossen ist, die mit den übertragenen Daten und den im Speicher abgelegten Worten die Information aufbaut. Bei der Ausgabeeinheit 15 kann es sich weiterhin um eine Sprachausgabesteuerung handeln, wie sie in der vorgenannten Druckschrift aufgezeigt ist oder es ist möglich, eine optische Anzeige, beispielsweise in Form eines Informations­bandes als LCD-Display vorzusehen. Bei einer Sprachausgabe wird das aufbereitete Sprachsignal dem Endverstärker 12 zugeführt und dann über den Lautsprecher 16 übertragen. Bei einer optischen Übertragung steuert die Ausgabeeinheit 15 die Anzeigeeinheit 17 an.Furthermore, an RDS receiver 13 is connected to the high and intermediate frequency part 11, as is known for example from the aforementioned document. This RDS receiver acts on a memory 14, to which in turn an output unit 15 is connected, which builds up the information with the transmitted data and the words stored in the memory. The output unit 15 can also be a voice output control, as shown in the aforementioned publication, or it is possible to provide an optical display, for example in the form of an information tape as an LCD display. In the case of a speech output, the processed speech signal is fed to the power amplifier 12 and then transmitted via the loudspeaker 16. In the case of an optical transmission, the output unit 15 controls the display unit 17.

Durch die spezielle Ausgestaltung des Speichers 14 wird erreicht, daß eine Ausgabe der beabsichtigten Information mit einem Minimum an übertragenen Daten gewährleistet ist. Hierbei wird vorausgesetzt, daß jede Straße in Segmente aufgeteilt ist, die dem Autofahrer für sich verständlich sind. Betrachtet man beispielsweise die Autobahn A7, so wäre ein Segment beispielsweise durch die größeren Orte Hannover und Kassel definiert, die den meisten Benutzern dieser Strecke bekannt sind. In dem Speicher 14 werden nun diese Segmente 22 straßenorientiert abgelegt. Jeder Straße ist daher ein bestimmter Bereich 20 zugeordnet, in dem die Segmente 22 angeordnet sind.The special design of the memory 14 ensures that the intended information is output with a minimum of transmitted data. It is assumed that that each street is divided into segments that the driver can understand. Looking at the A7 motorway, for example, a segment would be defined, for example, by the larger towns of Hanover and Kassel, which are known to most users of this route. These segments 22 are now stored in the memory 14 in a street-oriented manner. Each street is therefore assigned a specific area 20 in which the segments 22 are arranged.

Diese Segmente 22 sind nunmehr in einzelne Streckensegmente 21 un­tergliedert, die in aufsteigender Folge gespeichert sind. So ist es beispielsweise möglich, dem ersten Segment die Streckensegmente 1 bis 100, dem zweiten Segment die Streckensegmente 101 bis 200 usw. zuzuordnen. Die Streckensegmente selbst sind vorteilhafterweise durch bestimmte Orte definiert, denen eine größere Bedeutung zu­kommt. Bei Autobahnen ist dies beispielsweise dadurch möglich, daß ein Steckensegment aus dem Abschnitt besteht, der durch zwei Auto­bahnausfahrten begrenzt ist. Hierbei braucht das Steckensegment 21 nicht durch eine Strecke gekennzeichnet sein, vielmehr ist es hin­reichend, wenn ein Steckensegment durch einen Ort definiert ist, der beispielsweise in Nord-Süd-Richtung oder in Ost-West-Richtung gesehen am Anfang der Strecke liegt. So ist es beispielsweise mög­lich, im Segment "Hannover-Kassel" ein Streckensegment "Hildesheim" zu kennzeichnen, was sich dann von der Ausfahrt Hildesheim bis zur Autobahnausfahrt Holle erstreckt. Das dem Streckensegment "Hildesheim" folgende Streckensegment "Holle" definiert nunmmehr beispielsweise die Strecke zwischen den Autobahnausfahrten Holle und Salzgitter-Abzweig.These segments 22 are now subdivided into individual track segments 21, which are stored in ascending order. For example, it is possible to assign route segments 1 to 100 to the first segment, route segments 101 to 200 to the second segment, and so on. The route segments themselves are advantageously defined by certain locations that are of greater importance. In the case of motorways, this is possible, for example, in that a plug segment consists of the section which is delimited by two motorway exits. Here, the plug segment 21 does not need to be characterized by a route, rather it is sufficient if a plug segment is defined by a location which, for example, is located at the beginning of the route in the north-south direction or in the east-west direction. For example, it is possible to mark a route segment "Hildesheim" in the "Hanover-Kassel" segment, which then extends from the Hildesheim exit to the Holle motorway exit. The route segment "Holle" following the route segment "Hildesheim" now defines, for example, the route between the motorway exits Holle and Salzgitter junction.

Aufgrund des so ausgebildeten Speicheraufbaus ist es für den Emp­fänger hinreichend, wenn für eine Verkehrsmeldung lediglich das be­troffene Streckensegment und die Fahrtrichtung übertragen wird, so daß mit der bereits übertragenen Art des Hinweises eine vollständige Verkehrsmeldung aufgebaut werden kann. Durch die Übertragung der Straße wird erreicht, daß im Empfängerspeicher 14 lediglich der Be­reich 20 ansprechbar ist, der die entsprechende Straßenkennzeichnung besitzt. Durch die Übertragung des Streckensegments 21 ist aufgrund der Anordnung des Streckensegments im Speicher festgelegt, welches Segment 22 betroffen ist. Außerdem wird durch die Übertragung der Fahrtrichtung festgestellt, durch welche Grenzen das Streckensegment 21 begrenzt ist. Wird als Streckensegment 21 beispielsweise die Num­mer 128 aufgerufen, so ist bei Fahrtrichtung von Nord nach Süd fest­gelegt, daß dem Streckensegment 128 das Streckensegment 129 folgen muß, während bei einer Fahrt von Süd nach Nord dem Streckensegment 128 das Streckensegment 127 folgt. Das gleiche ist natürlich für die Ost- oder Westrichtung festzulegen. Mit den nun vorliegenden Infor­mationen ist es ohne Schwierigkeiten möglich, eine vollständige Ver­kehrsmeldung durchzugeben. Die Information der Straße ist, falls mehrere Straßen berücksichtigt werden müssen, bereits übermittelt, das Segment "Fahrtrichtung Hannover nach Kassel" ist einerseits durch die Fahrtrichtung und andererseits durch das übertragene Steckensegment 21 bestimmt, das in einem bestimmten Segment 22 zu finden ist, die Information, zwischen welchen Punkten ein Verkehrs­ereignis aufgetreten ist, nämlich beispielsweise zwischen Hildesheim und Holle ist ebenfalls einerseits durch die Fahrtrichtung und an­dererseits durch das Streckensegment 21 festgelegt, da bei einer be­stimmten Fahrtrichtung festgelegt ist, daß das eine Streckensegment "Hildesheim" und das in Fahrtrichtung folgende Streckensegment "Holle" heißt. Schließlich muß in bekannter Weise noch eine Informa­tion über die Art des Verkehrsereignisses übertragen werden, bei­spielsweise daß ein Stau wegen eines Unfalls gegeben ist. Die zu übertragenden Informationen beschränken sich also auf die Straße, die Fahrtrichtung, das Streckensegment und die Art des Verkehrser­eignisses.Because of the memory structure designed in this way, it is sufficient for the receiver if only the route segment concerned and the direction of travel are transmitted for a traffic report, so that a complete traffic report can be built up with the type of information already transmitted. The transmission of the street ensures that only the area 20 which has the corresponding street identification can be addressed in the receiver memory 14. Due to the arrangement of the route segment in the memory, the transmission of route segment 21 determines which segment 22 is affected. In addition, the transmission of the direction of travel determines the boundaries by which the segment 21 is limited. If, for example, the number 128 is called up as route segment 21, it is determined in the direction of travel from north to south that route segment 128 must be followed by route segment 129, while route segment 128 follows route segment 128 when traveling from south to north. The same is of course to be determined for the east or west direction. With the information now available, it is possible to submit a complete traffic report without difficulty. The information of the street is already transmitted if several streets have to be taken into account, the segment "direction Hanover to Kassel" is determined on the one hand by the direction of travel and on the other hand by the transmitted plug segment 21, which can be found in a certain segment 22, the information The points between which a traffic event occurred, namely between Hildesheim and Holle, for example, are also determined on the one hand by the direction of travel and, on the other hand, by route segment 21, since it is determined in a certain direction of travel that one route segment "Hildesheim" and the route segment following in the direction of travel "Holle" means. Finally, information about the type of traffic event must be transmitted in a known manner, for example that there is a traffic jam due to an accident. The information to be transmitted is therefore limited to the street, the direction of travel, the route segment and the type of traffic event.

Will man sich bei der Meldung nicht lediglich auf ein Streckenseg­ment beschränken, sondern sollen auch mehrere Streckensegmente von der Verkehrsmeldung erfaßt werden, ist eine zusätzliche Information nötig, die besagt, wieviel Streckensegmente von einem Verkehrser­eignis beeinflußt sind. Zu diesem Zweck ist es lediglich notwendig, die Zahl der interessierenden Streckensegmente 21 näher zu kenn­zeichnen und ebenfalls mit zu übertragen. Wird beispielsweise die Zahl 2 übertragen, deutet dies darauf hin, daß das Verkehrsereignis sich über zwei Streckensegmente erstreckt. Bei der Auswertung durch die Auswerteschaltung 15 wird daher neben dem Streckensegment 128 erst das übernächste Streckensegment, nämlich das Streckensegment 130 berücksichtigt. Dies bedeutet, daß sich das Verkehrsereignis nicht zwischen Hildesheim und Holle als Beginn des nächsten Streckensegments abspielt, sondern beispielsweise zwischen Hildesheim und Salzgitter-Abzweig, da dies bei dem gewählten Bei­spiel der Anfang des Streckensegments 130 ist.If you do not want to limit yourself to just one route segment during the report, but if several route segments are also to be covered by the traffic report, additional information is required which states how many route segments are affected by a traffic event. For this purpose, it is only necessary to identify the number of route segments 21 of interest in greater detail and also to transmit them. If the number 2 is transmitted, for example, this indicates that the traffic event extends over two route segments. In the evaluation by the evaluation circuit 15, therefore, in addition to the route segment 128, only the next but one route segment, namely the route segment 130, is taken into account. This means that the traffic event does not take place between Hildesheim and Holle as the start of the next route segment, but for example between Hildesheim and the Salzgitter junction, since in the selected example this is the beginning of route segment 130.

Durch den zuvor beschriebenen Aufbau des Speichers 14 im Empfänger ist es daher möglich, die digitalisierten Verkerhrshinweise wesent­lich kürzer zu fassen. Durch die spezielle Ausgestaltung des Emp­fängers wird erreicht, daß die Signalübertragung und -auswertung im Empfänger wesentlich schneller vorgenommen werden kann, so daß im gleichen Zeitraum die Zahl der zu empfangenen Verkehrshinweise er­höht ist. Dies kann beispielsweise auch dazu genutzt werden, die Redundanz der empfangenen Signale zu erhöhen, so daß Störungen leicht zu unterdrücken sind.Due to the above-described structure of the memory 14 in the receiver, it is therefore possible to make the digitized traffic instructions much shorter. The special design of the receiver ensures that the signal transmission and evaluation in the receiver can be carried out much faster, so that the number of traffic information to be received is increased in the same period. This can also be used, for example, to increase the redundancy of the received signals, so that interference can be easily suppressed.
