Die Erfindung betrifft ein Verfahren zur Informationsübermittlung von einer Strecke an ein Fahrzeug, bei dem streckenseitig punktförmig über eine Gleiskoppelspule Datentelegramme mit einem Startteil und einem Restteil an eine fahrzeugseitige Empfangseinrichtung gesendet werden, wenn die Gleiskoppelspule von dem Fahrzeug passiert wird, bei dem in Fahrtrichtung vor der Gleiskoppelspule fahrzeugpositionsunabhängig in Perioden Schleifentelegramme zur Vorabinformation über den Inhalt der Datentelegramme ausgesendet werden und bei dem als Schleifentelegramme die Datentelegramme unverändert verwendet werden. Die Erfindung betrifft ferner eine streckenseitige Einrichtung zur Durchführung des Verfahrens.The invention relates to a method for transmitting information from a track to a vehicle on the track side point telegrams via a track coupling coil with a starting part and a remaining part to one vehicle-side receiving device are sent when the Track coupling coil is passed by the vehicle in which Direction of travel in front of the track coupling coil regardless of vehicle position in periods loop telegrams for advance information sent out about the content of the data telegrams and the data telegrams as loop telegrams can be used unchanged.

Aus der DE 42 02 782 A1 ist eine Einrichtung zur Übertragung
von Informationstelegrammen bekannt. Zur Vermeidung gegenseitiger
Störungen beim gleichzeitigen Betrieb mehrerer
Einrichtungen wird den Informationstelegrammen ein systemerkennbar
abgesetztes Kopftelegramm mit der Angabe des Datenformats
des nachfolgenden Informationstelegramms vorausgeschickt.
Die DE- DE 37 02 527 C2 lehrt eine einkanalige Datenübertragungseinrichtung, die ohne Prüftelegramme und mit einer vergleichsweise kurzen Einlesezeit für zu übertragende Datentelegramme auskommt, indem den mehrfach übertragenen, inhaltsgleichen Telegrammen jeweils ein individueller, signifikant unterschiedlicher Telegrammkopf vorangestellt wird. DE-DE 37 02 527 C2 teaches a single-channel data transmission device, those without test telegrams and with one comparatively short read-in time for those to be transferred Data telegrams by using the multiple transmitted telegrams with the same content each an individual, significantly different telegram header becomes.
Ein Verfahren und eine Einrichtung der eingangs genannten Art
sind aus dem Prospekt "PUNKTFÖRMIGE ZUGBEEINFLUSSUNG / DAS ZUGBEEINFLUSSUNGSSYSTEM
ZUB 100" der Siemens AG, Bestell-Nr. A25090-A543-A116-3,
PA 03931.0 bekannt. Dieser Prospekt beschreibt
eine Einrichtung, die an entscheidenden Streckenpunkten wie
Signalstandorten oder vor Langsamfahrstellen, Informationen
von der Strecke auf das Fahrzeug überträgt. Diese Informationen
können zur Überwachung der Zughöchstgeschwindigkeit,
Ausgabe optischer oder akustischer Warnsignale, Bremsvorgaben
oder Zwangsbremsungen und/oder zur Überwachung des
Fahrzeugführers dienen. Die situations- oder signalbegriffsabhängigen
Informationen werden in Form von Datentelegrammen
mit festgelegter Datenstruktur von einer streckenseitigen
sogenannten Gleiskoppelspule auf eine korrespondierende
sogenannte Fahrzeugkoppelspule übertragen. Zum Erzeugen des
jeweils aktuell gültigen Datentelegramms dient ein Telegrammgenerator.
Jedes Datentelegramm beginnt mit einem
Startkopf (Startteil), der ein besonderes Zeichen zur
Synchronisation enthält. An den Startteil schließt sich ein
Restteil an, der Nutzdaten (beispielsweise 64 Nutzbits), eine
Codeüberwachung und einen Stoppblock umfaßt.A method and a device of the type mentioned at the beginning
are from the prospectus "POINT-BASED INFLUENCE / THE
Zur Kommunikation zwischen Strecke und Fahrzeug ist ein mehrkanaliges Übertragungssystem vorgesehen, wobei die Gleiskoppelspule einen passiven Kontrollkreis (50 kHz), einen Energieempfangskreis (100 kHz) und eine Sendeeinrichtung (850 kHz) zum Aussenden der Datentelegramme aufweist. Durch Rückwirkung des Kontrollkreises auf einen Überwachungskanal (Resonanz-Sendeschwingkreis mit 50 kHz) der Fahrzeugkoppelspule wird das Überfahren der Gleiskoppelspule angezeigt. Beim Passieren der Gleiskoppelspule nimmt der Energieempfangskreis fahrzeugseitig über einen 100-kHz-Schwingkreis abgestrahlte Energie für die Versorgung der Sendeeinrichtung auf. Die gesendeten Datentelegramme werden von einer korrespondierenden Empfangseinrichtung in der Fahrzeugkoppelspule empfangen, an die ein Fahrzeuggerät zur weiteren Verarbeitung und Auswertung der Datentelegramme angeschlossen ist.There is a multi-channel for communication between track and vehicle Transmission system provided, the track coupling coil a passive control circuit (50 kHz), an energy receiving circuit (100 kHz) and a transmitter (850 kHz) for sending the data telegrams. By Reaction of the control circuit on a monitoring channel (Resonant transmission resonant circuit with 50 kHz) of the vehicle coupling coil overrun of the track coupling coil is displayed. When passing the track coupling coil, the energy receiving circuit takes on the vehicle side via a 100 kHz resonant circuit radiated energy for the supply of the transmitting device on. The data telegrams sent are sent by a corresponding Receiving device in the vehicle coupling coil received to which a vehicle device for further processing and evaluation of the data telegrams is connected.
Um schon frühzeitig vor der Gleiskoppelspule dem Fahrzeug Vorabinformationen z. B. über Situationen (beispielsweise geänderter Signalbegriff) übermitteln zu können, ist eine der Gleiskoppelspule entgegen der Fahrtrichtung vorgeordnete Sendeschleife vorgesehen. Die Sendeschleife ist über eine Ansteuerschaltung ebenfalls von dem Telegrammgenerator beaufschlagbar und sendet periodisch spezifisch zu kennzeichnende Schleifentelegramme zur Information über den Inhalt des aktuellen Datentelegramms aus.To get the vehicle early in front of the track coupling coil Preliminary information e.g. B. about situations (for example being able to transmit a modified signal term) is one of the Track coupling coil upstream against the direction of travel Send loop provided. The send loop is over one Control circuit can also be acted upon by the telegram generator and sends periodically specific to be labeled Loop telegrams for information about the content of the current data telegram.
Die auch im Hinblick auf eindeutige Positionsinformationen dahingehend, ob sich das Fahrzeug (noch) über der Sendeschleife oder bereits über der Gleiskoppelspule befindet, wünschenswerte Kennzeichnung der Schleifentelegramme könnte durch eine einzufügende Kennung (Bitgruppe) erfolgen. Dazu müßten jedoch die von dem Telegrammgenerator gelieferten Datentelegramme mit erheblichem schaltungs- und steuerungstechnischem Aufwand modifiziert werden.Which also with regard to clear position information whether the vehicle is (still) over the transmit loop or is already above the track coupling coil, desirable labeling of the loop telegrams could by means of an identifier (bit group) to be inserted. To However, the data telegrams supplied by the telegram generator would have to with considerable circuit and control technology Effort to be modified.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Informationsübermittlung von einer Strecke an ein Fahrzeug zu schaffen, bei dem die periodisch ausgesendeten Schleifentelegramme zuverlässig als solche identifiziert und von den über die Gleiskoppelspule ausgesendeten Datentelegrammen unterschieden werden können.The invention is therefore based on the object of a method for transmitting information from a route to a vehicle to create where the periodically broadcast Loop telegrams reliably identified as such and from the data telegrams transmitted via the track coupling coil can be distinguished.
Diese Aufgabe wird bei einem Verfahren der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß zu Beginn der jeweiligen Periode vorab zumindest ein unvollständiges Schleifentelegramm gesendet wird, wobei aber zumindest der Startteil des Datentelegramms gesendet wird, und daß die so erzeugte Aufeinanderfolge mehrerer Startteile von der fahrzeugseitigen Empfangseinrichtung erkannt wird. Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens besteht darin, daß zum Erzeugen der Datentelegramme ohnehin vorhandene Schaltungsteile auch zum Erzeugen bzw. Kennzeichnen der Schleifentelegramme verwendet werden können. Dazu ist lediglich eine vergleichsweise einfache Steuerung erforderlich, die zu Beginn der jeweiligen Periode vorab ein von der fahrzeugseitigen Empfangseinrichtung erkennbares Startsignal (Startschritt) dadurch erzeugt, daß zumindest der Startteil des unveränderten, als Schleifentelegramm ausgesendeten Datentelegramms zumindest zweifach aufeinanderfolgend ausgesendet wird. Die Empfangseinrichtung erhält damit ein zuverlässig erkennbares spezifisches Zeichen zur Identifizierung einer Folge von Schleifentelegrammen, ohne daß die als Schleifentelegramme dienenden Datentelegramme in ihrer Bitstruktur modifiziert werden müssen. Dadurch kann auf bereits vorhandene und bewährte streckenseitige Einrichtungen zurückgegriffen werden; bereits installierte Zugbeeinflussungssysteme können einfach nachgerüstet werden (Aufwärtskompatibilität).This task is carried out in a method of the type mentioned at the beginning Art solved according to the invention in that at the beginning of at least one incomplete period in advance Loop telegram is sent, but at least the Start part of the data telegram is sent, and that the so generated Sequence of several starting parts from the vehicle side Receiving device is recognized.

Die Erfindung wird nachfolgend anhand einer Zeichnung weiter
erläutert; es zeigen:
Figur 1 zeigt schematisch einen Streckenabschnitt STR mit
zwei Schienen 1, 2 und ein darauf in Fahrtrichtung A verkehrendes
Fahrzeug FZ mit einem Zugbeeinflussungssystem, das
grundsätzlich in dem eingangs genannten Prospekt "PUNKTFÖRMIGE
ZUGBEEINFLUSSUNG" beschrieben ist. Der Streckenabschnitt STR ist
mit einer streckenseitigen Einrichtung 10 ausgerüstet, die
mit einer korrespondierenden, fahrzeugseitigen Einrichtung 20
zusammenwirkt. Die Einrichtung 20 umfaßt wie eingangs
erläutert einen 50 kHz-Kontrollschwingkreis, einen 100 kHz-Energiesendekreis
und eine Empfangseinrichtung, die auf einer
Frequenz von 850 kHz arbeitet. Diese Komponenten sind in
Figur 1 zusammenfassend als Fahrzeugkoppelspule FZS bezeichnet,
an die zur Auswertung und zum bedarfsweisen Eingriff in
Steuerorgane (z. B. Bremsen) des Fahrzeugs FZ ein Fahrzeugrechner
FR angeschlossen ist.Figure 1 schematically shows a route section STR

Die streckenseitige Einrichtung 10 dient zur Information,
Kontrolle und ggf. Beeinflussung (z. B. Bremsung) des Fahrzeugs
FZ vor einem Signal 25 und umfaßt zur Bildung von Übertragungskanälen
auf die korrespondierenden fahrzeugseitigen
Frequenzen abgestimmte Schwingkreise einer Gleiskoppelspule
GKS. Ein passiver 50 kHz-Kontrollkreis bewirkt durch einen
Stromabfall in dem fahrzeugseitigen Kontrollschwingkreis eine
Positionsmeldung. Ein 100 kHz-Energieempfangskreis nimmt auf
dieser Frequenz von dem fahrzeugseitigen Energiesendekreis
abgestrahlte Energie auf, um damit einen Telegrammgenerator
und eine mit 850 kHz arbeitende Sendeeinrichtung mit einem
Sendeverstärker SV und einer Antenne ANT (Figur 2) zu
speisen. Entgegen der Fahrtrichtung A ist der Gleiskoppelspule
GKS eine Sendeschleife SS vorgeordnet. Zur Abfrage des
Signalbegriffs und zur Energieentnahme aus dem Signallampenkreis
ist die Einrichtung 10 über Leitungen 28, 29 mit dem
Signal 25 verbunden.The
Gemäß Figur 2 sind in der Gleiskoppelspule GKS nicht nur die
vorgenannten Schwingkreise und ein Spannungsstabilisator 30
angeordnet, sondern auch eine Steuereinrichtung SE und ein
Telegrammgenerator 32, der von einer Telegrammsteuerschaltung
34 und einem aus Sicherheitsgründen zweifach (Redundanz)
vorgesehenen und alternierend abfragbaren Telegrammspeicher
35 gebildet ist.According to Figure 2, the track coupling coil GKS is not only the
aforementioned resonant circuits and a
Die Sendeschleife SS ist von einem Sendeschleifenverstärker
SSV und einer Steuerlogik SL mit Schleifentelegrammen STEL
beaufschlagbar. Um die Sendeschleife SS mit einer vorgebbaren
Periode pulsartig zu aktivieren, schaltet die Steuereinrichtung
SE eine dem Signallampenkreis entnommene und über die
Leitung 29 der Steuerlogik SL zugeführte Versorgungsspannung
U1b zur Telegrammerzeugung als Spannung U1 auch auf den Telegrammgenerator
32 durch. Als Schleifentelegramme werden dem
Sendeschleifenverstärker SSV über eine Leitung 37 die von dem
Telegrammgenerator signalbegriffsabhängig erzeugten Datentelegramme
DTEL unverändert zugeführt. Über eine Steuerleitung
38 erkennt die Steuerlogik SL jeweils das Ende eines Datentelegramms
des Datentelegrammgenerators 32 und kann so nach Erreichen
der gewünschten Anzahl in der jeweiligen Periode auszugebender
Schleifentelegramme deren Angabe bis zum Beginn
der nächsten Periode beenden. Unabhängig davon ist die
Gleiskoppelspule GKS vorteilhafterweise zur Kommunikation mit
einem passierenden Fahrzeug über die Sendeeinrichtung SEN
weiterhin stets betriebsbereit. Wenn ein Fahrzeug mit seiner
Fahrzeugkoppelspule FZS (Figur 1) die Gleiskoppelspule über
den Energieempfangskreis mit einer Spannung U1a speist, wird
über den Sendeverstärker SV das aktuell von dem Telegrammgenerator
32 über eine Ausgangsleitung 40 zugeführte
Datentelegramm DTEL über die Antenne ANT gesendet. Der
Telegrammgenerator 32 wird über eine Diode D1, die Bestandteil

Figur 3 zeigt schematisch die zeitliche Angabe von Schleifentelegrammen
STEL, wobei zum Zeitpunkt to (Sendebeginn) zunächst
als Startschritt nur der Kopfabschnitt, d. h. ein unvollständiges
Schleifentelegramm STELU ausgegeben wird. Dazu
wird ein von dem Telegrammgenerator 32 (Figur 2) dem Sendeschleifenverstärker
SSV zugeführtes unverändertes Datentelegramm
DTEL nach dem Senden seines Startteils START abgebrochen.
Dies kann durch kurzzeitige Abschaltung der Versorgungsspannung
U1b oder (wie in Figur 2 explizit gezeigt)
durch Einwirken auf den Reseteingang der Telegrammsteuerschaltung
34 realisiert werden. Nach einer kurzen Sendeunterbrechung
von 0,15 ms sorgt die Steuereinrichtung SE durch
Beaufschlagung des Sendeschleifenverstärkers SV über die
Leitung 37 mit einem unveränderten Datentelegramm DTEL für
eine nunmehr vollständige Ausgabe eines Schleifentelegramms
STEL. Das Schleifentelegramm STEL entspricht in seiner
Bitstruktur dem unveränderten Datentelegramm DTEL mit dem
schon genannten Startteil START und einem Restteil REST mit
einem Kommandoabschnitt KOM, einer Codesicherung CD und einem
abschließenden Stoppschritt STOP. Dieses Schleifentelegramm
STEL kann mehrfach, vorzugsweise zweifach, ausgesendet
werden. Die zu Beginn einer jeden Periode P vorgesehene
unvollständige Aussendung eines Schleifentelegramms
(unverändertes Datentelegramm), wobei der Abbruch des Aussendens
frühestens nach dem Startteil START erfolgt, ergibt
eine Telegrammsendung mit zwei aufeinanderfolgenden Startteilen
START1, START2 (Doppelstartschritt DST). Der Doppelstartschritt
ist eine signifikante, von dem Fahrzeugrechner
FR erkennbare Markierung. Um die Zuverlässigkeit des Verfahrens
weiter zu erhöhen, sind direkt aufeinanderfolgende drei- oder
vierfache Startschritte vorteilhaft.FIG. 3 schematically shows the time specification of loop telegrams STEL, with only the header section, ie an incomplete loop telegram STELU, being output as the starting step at time t o (start of transmission). For this purpose, an unchanged data telegram DTEL fed from the telegram generator 32 (FIG. 2) to the transmission loop amplifier SSV is terminated after its start part START has been sent. This can be achieved by briefly switching off the supply voltage U1b or (as shown explicitly in FIG. 2) by acting on the reset input of the
Claims (2)
- Method for transmitting information from a track to a vehicle,in which, on the track side, data telegrams (DTEL) with a starting part (START) and a residual part (REST) are transmitted to a vehicle-side reception device (20) via a track coupling coil (GKS) in an intermittent fashion when the vehicle (FZ) passes the track coupling coil (GKS),in which loop telegrams (STEL) are emitted in periods (P) as a function of the vehicle position in the direction of travel (A) upstream of the track coupling coil (GKS) by means of a transmission loop in order to provide preliminary information on the content of the data telegrams (DTEL), andin which the data telegrams (DTEL) are used in unchanged form as loop telegrams (STEL), characterized in that, at the start (to) of the respective period (P), at least one incomplete loop telegram (STELU) is transmitted in advance, at least the starting part (START) of the data telegram (DTEL) being however transmitted, and in that the succession of a plurality of starting parts (START1, START2) which is generated in this way is detected by the vehicle-side reception device (20).
- Track-side device for carrying out the method according to Claim 1,having a telegram generator (32), which generates data telegrams (DTEL) with a starting part (START) and a residual part (REST),having a track coupling coil (GKS) having a transmission device (SEN), which is acted on by the telegram generator (32), in order to output the data telegrams (DTEL) to a vehicle-side reception device (20) when the vehicle (FZ) passes the track coupling coil (GKS), andhaving a transmission loop (SS), which is arranged upstream of the track coupling coil (GKS) counter to the direction of travel (A), is acted on by the telegram generator (32) by means of a drive circuit (SL, SSV), and periodically emits loop telegrams (STEL) independently of the position of the vehicle, in order to provide preliminary information on the contents of the data telegrams (DTEL), the transmission loop (SS) emitting the data telegrams (DTEL) in unchanged form as loop telegrams (STEL), characterized in that a control device (SE) is provided which is designed in such a way that the transmission loop (SS) transmits at least one incomplete loop telegram (STEL) in advance at the start of the respective period (P), for which purpose an emission of a loop telegram is aborted at the earliest after the emission of the starting part (START) of the data telegram.
