Description
Die Erfindung betrifft einen Empfänger mit einer Einrichtung zur Selektion von digital codierten Meldungen, die Ortsinformationen und weitere Informationen enthalten und jeweils als neue Meldung und als dazugehörige Wiederholungsmeldungen mit gegebenenfalls aktualisiertem Inhalt ausgestrahlt werden, wobei mindestens die neuen Meldungen im Empfänger gespeichert und wiedergegeben werden.The invention relates to a receiver with a device for the selection of digitally coded messages, the Location information and other information included and each as a new message and as associated Repeat messages with updated if necessary Content to be broadcast, with at least the new ones Messages are stored and played back in the receiver.
Zur Information von Autofahrern sind bereits seit längerer Zeit gesprochene Verkehrsdurchsagen bekannt. Diese sind mit verschiedenen Nachteilen behaftet, beispielsweise mit Verzögerungen und Ungenauigkeiten, die durch die manuelle und damit auch subjektive Aufnahme und Weitergabe der Informationen verbunden sind. So kommt es beispielsweise vor, daß ein Autofahrer in einen Stau gerät, der (noch) nicht angesagt wurde, oder daß er trotz Stauwarnung die betreffende Straße bei seinem Eintreffen an der bezeichneten Stelle relativ störungsfrei befahren kann. For information of motorists have been around for some time Time spoken traffic announcements known. These are with various disadvantages, for example, with Delays and inaccuracies caused by the manual and thus also subjective reception and transmission of the Information is connected. This is how it happens, for example that a motorist gets stuck in a traffic jam that (still) was not announced, or that despite the traffic jam warning the concerned road on its arrival at the designated Can ride relatively smoothly.
Eine genauere Erfassung sowie eine schnellere Übermittlung ist mit Hilfe des in den letzten Jahren bekanntgewordenen Systems zur Übermittlung digital codierter Verkehrsmeldungen möglich geworden. Der Aufbau und die Codierung dieser Verkehrsmeldungen und die Ortsliste sind in CEN pr ENV12313-1 und pr ENV/278/7/3/0004 festgelegt, der auf dem Normvorschlag ALERT C, Juni 1996, herausgegeben vom RDS ATT ALERT Consortium, basiert. Die wesentlichen Elemente einer Verkehrsmeldung sind dabei der Ort des Geschehens (Location) und das Ereignis (Event). Diese Angaben sind katalogisiert, das heißt, daß jedem verkehrsrelevanten Ort und jedem verkehrsrelevanten Ereignis ein eindeutiger Code zugewiesen ist. Die Verkettung der Orte in der Ortstabelle entlang existierender Straßen gibt den Verlauf wieder. Außer den üblichen Einrichtungen eines Empfangsgerätes mit einem RDS-Decoder sind zur Nutzung des Verkehrsmeldungskanals TMC (Traffic Message Channel) Einrichtungen zur Decodierung, zur Speicherung, zur Weiterverarbeitung und zur Ausgabe der Verkehrsmeldungen erforderlich.A more accurate capture and faster delivery has become known with the help of the in recent years System for transmitting digitally coded traffic reports become possible. The construction and coding of this Traffic announcements and the place list are in CEN pr ENV12313-1 and pr ENV / 278/7/3/0004, which are published on the Standard Proposal ALERT C, June 1996, issued by the RDS ATT ALERT Consortium, based. The essential elements of a Traffic information is the place of the event (Location) and the event. This information is cataloged, that is, every traffic-relevant place and everyone traffic-related event assigned a unique code is. The chaining of places in the place table along existing roads are the course again. Except the usual facilities of a receiving device with a RDS decoders are for use of the traffic message channel TMC (Traffic Message Channel) Facilities for decoding, for Storage, further processing and output of the Traffic reports required.
Digital codierte Verkehrsmeldungen - im folgenden auch TMC-Meldungen genannt - können mit dem Radio-Daten-System (RDS) übertragen werden, das eine zusätzliche und unhörbare Übermittlung von digitalen Daten parallel zu Rundfunkprogrammen in einem Datenkanal ermöglicht. Spezifikationen des Radio-Daten-Systems für UKW-Hörfunk sind unter anderem in der Druckschrift Tech. 3244 - E, März 1984 der europäischen Runfunk-Union (EBU) festgelegt. Rundfunkempfänger mit geeigneten RDS-Decodern können übermittelte Daten zusätzlich zum Audioempfang mit dem selben Empfangsteil aufnehmen und decodieren siehe z.B. DE19516477A1.Digitally coded traffic reports - also below TMC messages called - can be used with the radio data system (RDS), which is an additional and inaudible Transmission of digital data in parallel to Radio programs in a data channel allows. Specifications of the radio data system for FM radio are inter alia in the publication Tech. 3244 - E, March 1984 of the European Union of Run-Down Radio Union (EBU). Radio receivers with suitable RDS decoders can transmitted data in addition to the audio reception with the to record and decode the same receiver, see e.g. DE19516477A1.
Die TMC-Meldungen werden nicht nur einmal, sondern zyklisch wiederholt gesendet, solange der Inhalt noch aktuell ist, um auch Empfängern, die nach dem Aussenden einer neuen Meldung eingeschaltet wurden, noch aktuelle Meldungen zuführen zu können und um die Übertragungssicherheit zu erhöhen. Der Empfänger hat daher die Aufgabe, die Meldung zu speichern und jede empfangene Meldung gegen diesen Bestand zu überprüfen, um festzustellen, ob es sich um eine Wiederholungsmeldung oder um eine neue Meldung handelt. Nur im Falle einer neuen Meldung wird der Inhalt dem Fahrer mitgeteilt. Dabei gilt eine Meldung als neu, wenn sie entweder mit keiner der gespeicherten Meldungen übereinstimmt oder aber eine der vorhandenen Meldungen aktualisiert, beispielsweise die Veränderung der Staulänge, aber auch die Aufhebung einer Störung. Bei der Überprüfung der empfangenen Meldung mit dem Bestand an gespeicherten Meldungen wird eine Meldung als neu angesehen, wenn sie sich bezüglich der Ortsinformation, einer Richtungsinformation oder der Art des Ereignisses von den gespeicherten Meldungen unterscheidet.The TMC messages are not just once, but cyclically repeatedly sent as long as the content is still up to date also receivers after sending out a new message have been switched on, still supplying current messages can and to increase the transmission security. Of the The recipient therefore has the task of saving the message and any received message against that inventory Check to see if this is a Repeat message or is a new message. Just in the case of a new message, the content becomes the driver communicated. A message is considered new if it is either with none of the stored messages matches or one of the existing messages updated, for example the change in the storage length, but also the suspension of a disturbance. In the review the received message with the stock of stored Messages will see a message as new when they are with respect to the location information, direction information or the type of event from the stored messages different.
In Feldversuchen hat sich gezeigt, daß durch Fehler bei der Erstellung der Meldungen oder bei einem Wechsel von einem Diensteanbieter zu einem anderen die Häufigkeit der Meldungsaktualisierung zu hoch wurde. Im Extremfall wurden dabei Meldungen innerhalb einer Minute mehrfach geändert, was von Testpersonen als sehr störend empfunden wurde.Field tests have shown that errors in the Creation of messages or when changing from one Service provider to another the frequency of Message update became too high. In extreme cases were messages are changed several times within one minute, which was perceived by test persons as very disturbing.
Aufgabe der vorliegenden Erfindung ist es, einen Empfänger anzugeben, bei dem unter allen im Betrieb vorkommenden Situationen die Anzahl der Meldungsausgaben nicht als störend empfunden wird.The object of the present invention is a receiver to be specified, among which among all occurring in the company Do not put the number of message outputs as is distracting.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine neue Meldung nach dem Empfang gespeichert und mit einem Zeitstempel und mit einer Variablen versehen wird, die mindestens zwei Werte annehmen kann, von denen einer bewirkt, daß innerhalb einer vorgegebenen Zeit nach dem Zeitstempel eintreffende Wiederholungsmeldungen nicht abgespeichert und wiedergegeben werden. This object is achieved in that a new message stored after receipt and with a Timestamp and is provided with a variable that can take on at least two values, one of which causes within a predetermined time after the Timestamp incoming retry messages not be saved and played back.
Der Empfänger mit den erfindungsgemäßen Merkmalen hat den Vorteil, daß die Ausgabe von Wiederholungsmeldungen unabhängig von der Infrastruktur (Diensteanbietern, Rundfunkanstalten usw.) und daher zuverlässig ist. Es wird keine Information über den Meldungsursprung benötigt, wodurch das Meldungs-Management einfacher wird und Speicherplatz gegenüber anderen Lösungen eingespart wird.The receiver with the features according to the invention has the Advantage that the output of repeat messages regardless of the infrastructure (service providers, Broadcasters, etc.) and therefore reliable. It will no information about the message origin needed, which makes the message management easier and Space is saved over other solutions.
In dem erfindungsgemäßen Empfänger werden Löschmeldungen wie normale Wiederholungsmeldungen gehandhabt, was ebenfalls eine Vereinfachung im Meldungs-Management bewirkt. Das Problem der Meldungs-Präsentation bei widersprüchlichen Meldungsinhalten von verschiedenen Quellen tritt nicht mehr auf.In the receiver according to the invention are deletion messages such normal repeat messages handled, as well Simplification in message management causes. The Problem of message presentation in case of conflicting Message content from various sources no longer occurs on.
Eine Weiterbildung des erfindungsgemäßen Empfängers besteht darin, daß beim Empfang einer neuen Meldung die Variable auf denjenigen Wert gesetzt wird, der die Speicherung und Wiedergabe einer Wiederholungsmeldung gestattet und daß bei dem Empfang einer jeweils ersten Wiederholungsmeldung die Variable auf den anderen Wert gesetzt wird, daß beim Empfang weiterer Wiederholungsmeldungen geprüft wird, ob die vorgegebene Zeit nach Setzen der Variablen auf den anderen Wert vergangen ist, und daß zutreffendenfalls die empfangene weitere Wiederholungsmeldung abgespeichert und wiedergegeben wird und die Variable wieder auf den anderen Wert gesetzt wird.A development of the receiver according to the invention exists in that when receiving a new message, the variable on that value is set that the storage and Play a repeat message allowed and that at the receipt of a respective first repeat message the Variable is set to the other value that when receiving further repeat messages is checked whether the given time after setting the variable to the other Value has passed, and that, if applicable, the received further repeat message stored and reproduced and the variable is set to the other value again becomes.
Diese Weiterbildung stellt sicher, daß die erste Aktualisierung einer Meldung sehr schnell erfolgen kann, wodurch der Großteil der in der Realität auftretenden Fälle von für den Benutzer interessanten Aktualisierungen abgedeckt wird. This training ensures that the first Update a message very quickly, which accounts for the majority of cases occurring in reality of updates of interest to the user is covered.
Vorzugsweise ist bei dem erfindungsgemäßen Empfänger vorgesehen, daß die Variable durch ein einzelnes Bit dargestellt ist. Hierbei tritt ein Vorteil des erfindungsgemäßen Empfängers, daß nämlich nur wenig Speicherplatz benötigt wird, besonders deutlich hervor. Je nach Erfordernissen können jedoch für die Variable auch mehrere Bits vorgesehen sein.Preferably, in the inventive receiver provided that the variable by a single bit is shown. This is an advantage of according to the invention, namely that only a little Storage space is needed, especially clear. ever however, as required, for the variable as well several bits can be provided.
Je nach persönlichem Geschmack des Benutzers, dem jeweiligen Einsatzgebiet des Fahrzeugs und anderen Umständen kann die als störend empfundene Zahl von wiedergegebenen Wiederholungsmeldungen verschieden groß sein. Bei einer anderen Weiterbildung des erfindungsgemäßen Empfängers ist daher vorgesehen, daß die vorgegebene Zeit vom Benutzer voreinstellbar ist.Depending on the personal taste of the user, the respective Operational area of the vehicle and other circumstances may be the annoying number of reproduced Repeat messages vary in size. At a another embodiment of the inventive receiver Therefore, provided that the predetermined time by the user is presettable.

Der in Fig. 1 dargestellte Empfänger weist in an sich
bekannter Weise eine Antenne 1, ein Empfangsteil 2, einen
Stereo-Decoder 4, einen NF-Verstärker 5 sowie
Leistungsverstärker 6, 7 und Lautsprecher 8, 9 auf. Das von
dem Empfangsteil 2 abgegebene Stereo-Multiplexsignal wird
außer dem Stereo-Decoder 4 einem RDS-Decoder 3 zugeführt,
dessen Ausgang mit einem Mikrocomputer 13 verbunden ist. Der
Mikrocomputer 13 dient neben der Steuerung des Empfängers
zur Decodierung, Verwaltung, Aufbereitung für die Wiedergabe
und Selektion der TMC-Meldungen. An den Mikrocomputer 13 ist
eine Tastatur 14 und eine Anzeigevorrichtung (Display) 15
angeschlossen. Die Ausgabe der selektierten TMC-Meldungen
kann entweder über das Display 15 oder als Sprachausgabe
erfolgen, wozu der Mikrocomputer 13 über einen
Sprachsynthesizer 16 mit einem Eingang 10 des NF-Verstärkers
5 verbunden ist.The receiver shown in Fig. 1 has in itself
a known manner, an
Fig. 2 zeigt ein Ablaufdiagramm der Meldungsaktualisierung, die als Programm im Mikrocomputer 13 (Fig. 1) beim Empfang einer Meldung abgearbeitet wird. Nach einem Start bei 21 wird eine Meldung TMC von einer im Mikrocomputer 13 vorgesehenen Kommunikationseinheit abgeholt und decodiert. Bei 23 wird diese Meldung mit dem aktuellen Bestand an gespeicherten Meldungen TMC1 bis TMCn verglichen. Bei 24 erfolgt eine Verzweigung in Abhängigkeit davon, ob die Meldung eine neue TMC-Meldung NTMC ist. Ist dieses der Fall, wird bei 26 die Meldung abgespeichert, mit einem Zeitstempel TS, der der aktuellen Uhrzeit H entspricht, und der Variablen - im folgenden Up-Date-Sperre US genannt - versehen. Bei 32 erfolgt die Ausgabe der neuen Meldung. Das Programm wird dann bei 30 beendet.FIG. 2 shows a flow chart of the message update. FIG. that as a program in the microcomputer 13 (Fig. 1) when receiving a message is processed. After a start at 21 a message TMC from one in the microcomputer 13th intended communication unit picked up and decoded. At 23, this message appears with the current inventory stored messages TMC1 to TMCn compared. At 24 a branch takes place depending on whether the Message is a new TMC message NTMC. Is this the case the message is stored at 26, with a time stamp TS, which corresponds to the current time H, and the Variables - called Up-Date-Barrier US below - Mistake. At 32, the new message is output. The Program will end at 30.
Ist bei der Verzweigung 24 die Meldung nicht neu, wird bei
25 abgefragt, ob die Up-Date-Sperre US aktiv ist. Trifft
dieses zu, erfolgt bei 27 ein Vergleich des Zeitstempels TS
mit der aktuellen Uhrzeit H. Bei 28 erfolgt eine Verzweigung
in Abhängigkeit davon, ob die bei 27 ermittelte
Zeitdifferenz H-TS größer als die Sperrzeit ST ist.
Zutreffendenfalls wird bei 29 die Meldung aktualisiert, das
heißt die bis dahin gespeicherte Meldung durch eine
Wiederholungsmeldung überschrieben und mit einem Zeitstempel
TS versehen. Ferner wird die Up-Date-Sperre US aktiviert und
bei 32 die Meldung ausgegeben. If at
War hingegen die Up-Date-Sperre US bei der Prüfung 25 nicht
aktiv, so findet ein direkter Sprung nach 29 statt. Auch
diese Meldung wird bei 32 ausgegeben.On the other hand, the up-date lock US was not on
Ist jedoch die Differenz zwischen der Uhrzeit H und dem Zeitstempel TS nicht größer als die Sperrzeit ST, wird bei 31 die Meldung verworfen und das Programm bei 30 beendet.However, if the difference between the time H and the Time stamp TS not greater than the blocking time ST, is added 31 discarded the message and the program ended at 30.
