Verfahren und Einrichtung zum Erkennen hinterherfahrender Fahrzeuge Method and device for detecting vehicles traveling behind
Der Betrieb von Streckennetzen, insbesondere Eisenbahnstre ckennetzen, auf der Basis von Fahrzeugen, die ihre Position selbst regelmäßig oder unregelmäßig ermitteln und an eine Zentraleinrichtung übermitteln, ist beispielsweise im Zusam menhang mit Systemen gemäß dem ETCS Level 3 bekannt. Die Zentraleinrichtung kann auf der Basis erhaltener Informatio nen die Steuerung und Leitung des Verkehrs im Streckennetz vornehmen . The operation of route networks, in particular railway route networks, on the basis of vehicles which determine their position regularly or irregularly and transmit it to a central facility is known, for example, in connection with systems according to ETCS Level 3. The central facility can control and manage the traffic in the route network on the basis of information obtained.
Bei solchen Systemen kann das Problem auftreten, dass der Zentraleinrichtung nicht alle im Streckennetz fahrenden Fahr zeuge bekannt sind, beispielsweise wenn ein Fahrzeug aufgrund eines Defekts seine Positionen nicht übermittelt. In such systems, the problem can arise that the central device does not know all the vehicles traveling in the route network, for example if a vehicle does not transmit its positions due to a defect.
Ausgehend von der beschriebenen Problematik liegt der Erfin dung die Aufgabe zugrunde, ein Verfahren zum Erkennen eines einem vorausfahrenden Fahrzeug in einem vorgegebenen Stre ckenabschnitt einer Fahrstrecke unmittelbar hinterherfahren den Fahrzeugs anzugeben. Based on the problem described, the invention is based on the object of specifying a method for recognizing a vehicle driving directly in front of a vehicle in a predetermined route section of a route.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen gemäß Patentanspruch 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind in Un teransprüchen angegeben. This object is achieved according to the invention by a method with the features according to patent claim 1. Advantageous refinements of the method according to the invention are specified in sub-claims.
Danach ist erfindungsgemäß vorgesehen, dass mit einer Stre- ckenabschnittsüberwachungseinrichtung, die einen vorgegebenen Streckenabschnitt auf das Besetztsein oder Unbesetztsein überwacht, ein Freimeldungssignal erzeugt wird, sobald der Streckenabschnitt nach einem vorherigen Besetztzustand wieder fahrzeugfrei wird, unter Heranziehung einer den Zeitpunkt des Freiwerdens angebenden, streckenseitigen Zeitangabe der Stre- ckenabschnittsüberwachungseinrichtung, einer Ortsinformation des vorausfahrenden Fahrzeugs, die nach dem Verlassen des Streckenabschnitts von dem vorausfahrenden Fahrzeug zu einem Ortsermittlungszeitpunkt ermittelt worden ist, einer den Ortsermittlungszeitpunkt angebenden, fahrzeugseitigen Zeitan gabe und einer die Geschwindigkeit des vorausfahrenden Fahr zeugs angebenden Geschwindigkeitsangabe, der Ort des Fahrzeu gendes des vorausfahrenden Fahrzeugs zum Zeitpunkt des Frei werdens des Streckenabschnitts errechnet wird, der Abstand zwischen dem Abschnittsende des Streckenabschnitts und dem errechneten Ort des Fahrzeugendes ermittelt wird und anhand des Abstands geprüft wird, ob dem vorausfahrenden Fahrzeug ein Fahrzeug unmittelbar hinterherfährt. According to the invention, it is provided that a route section monitoring device, which monitors a given route section for whether it is occupied or unoccupied, generates a release signal as soon as the route section becomes vehicle-free again after a previous occupied state, using a route-side time indication indicating the time of the release the route section monitoring device, location information of the preceding vehicle, which has been determined after leaving the route section by the preceding vehicle at a location determination time, a vehicle-side time indication indicating the location determination time and a speed indication indicating the speed of the vehicle driving ahead, the location of the vehicle end of the preceding vehicle at the time the route section is cleared, the distance between the section end of the route section and the calculated location of the vehicle end is determined, and the distance is used to check whether the vehicle in front is traveling directly behind a vehicle.
Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens be steht darin, dass ein hinterherfahrendes Fahrzeug, das selbst keine Ortsinformationen aussendet und somit für eine überge ordnete Zentraleinrichtung nicht "sichtbar" ist, dennoch er kannt werden kann, indem Ortsinformationen des diesem "un sichtbaren" Fahrzeug vorausfahrenden Fahrzeugs sowie Signale einer Streckenabschnittsüberwachungseinrichtung in der ange gebenen Weise ausgewertet werden. A major advantage of the method according to the invention is that a vehicle traveling behind, which itself does not emit any location information and is therefore not "visible" to a higher-level central device, can nevertheless be known by location information of the vehicle driving in front of this "invisible" vehicle and signals from a section monitoring device are evaluated in the manner indicated.
Vorteilhaft ist es, wenn ein Erkennungssignal erzeugt wird, das ein unmittelbar hinterherfahrendes Fahrzeug anzeigt, wenn der Abstand zwischen dem Abschnittsende des Streckenab schnitts und dem errechneten Ort des Fahrzeugendes größer als eine vorgegebene Auslöselänge ist. It is advantageous if a detection signal is generated which indicates a vehicle traveling directly behind if the distance between the end of the section of the section and the calculated location of the end of the vehicle is greater than a predetermined trigger length.
Auch ist es von Vorteil, wenn ein Ausgangssignal erzeugt wird, das anzeigt, dass kein unmittelbar hinterherfahrendes Fahrzeug vorhanden ist, wenn der Abstand zwischen dem Ab schnittsende des Streckenabschnitts und dem errechneten Ort des Fahrzeugendes kleiner als die vorgegebene Auslöselänge ist . It is also advantageous if an output signal is generated which indicates that there is no vehicle immediately behind if the distance between the end of the section of the route and the calculated location of the end of the vehicle is less than the predetermined trigger length.
Die Fahrstrecke wird vorzugsweise ausschließlich von Fahrzeu gen befahren, die mindestens so lang wie die vorgegebene Aus löselänge sind. Die Fahrzeuge sind vorzugsweise Schienenfahrzeuge. The route is preferably driven exclusively by vehicles that are at least as long as the specified trigger length. The vehicles are preferably rail vehicles.
Die Ortsinformation des vorausfahrenden Fahrzeugs wird vor zugsweise fahrzeugseitig auf der Basis eines Balisensignals einer streckenseitigen Balise ermittelt. Zusätzlich oder al ternativ kann die Ortung auch auf andere Weise, beispielswei se satellitenbasiert, erfolgen. The location information of the preceding vehicle is preferably determined on the vehicle side based on a balise signal from a track-side balise. In addition or alternatively, the location can also be done in a different way, for example by satellite.
Die Streckenabschnittsüberwachungseinrichtung ist bevorzugt eine Gleisfreimeldeeinrichtung. The section monitoring device is preferably a track vacancy detection device.
Als besonders vorteilhaft wird es angesehen, wenn die Stre- ckenabschnittsüberwachungseinrichtung die den Zeitpunkt des Freiwerdens angebende, streckenseitige Zeitangabe an eine streckenseitige Zentraleinrichtung übermittelt, das Fahrzeug die Ortsinformation, die fahrzeugseitige Zeitangabe und die Geschwindigkeitsangabe an die streckenseitige Zentraleinrich tung übermittelt und die Zentraleinrichtung prüft, ob dem vo rausfahrenden Fahrzeug ein Fahrzeug unmittelbar hinterher fährt . It is considered to be particularly advantageous if the route section monitoring device transmits the route-side time indication indicating the time of the release to a route-side central device, the vehicle transmits the location information, the vehicle-side time information and the speed information to the route-side central device and the central device checks whether a vehicle is driving directly behind the vehicle in front.
Das vorausfahrende Fahrzeug übermittelt als Ortsinformation vorzugsweise eine unmittelbar den Ort des Fahrzeugendes ange bende Ortsinformation an die Zentraleinrichtung. The vehicle in front preferably transmits as location information a location information directly indicating the location of the vehicle end to the central device.
Alternativ kann in vorteilhafter Weise vorgesehen sein, dass sich die Ortsinformation des vorausfahrenden Fahrzeugs auf den Fahrzeuganfang bezieht und der Ort des Fahrzeugendes an hand der auf den Fahrzeuganfang bezogenen Ortsinformation und einer die Länge des vorausfahrenden Fahrzeugs angebenden Län genangabe ermittelt wird. Alternatively, it can advantageously be provided that the location information of the vehicle in front relates to the vehicle start and the location of the vehicle end is determined on the basis of the location information related to the vehicle start and a length indicating the length of the vehicle in front.
Die Zentraleinrichtung ist vorzugsweise ein Stellwerk, ein Zugsicherungssystem oder eine Leitzentrale . The central device is preferably a signal box, a train protection system or a control center.
Das Prüfen, ob dem vorausfahrenden Fahrzeug ein Fahrzeug un mittelbar hinterherfährt, kann alternativ oder zusätzlich auch von einer Prüfeinrichtung des vorausfahrenden Fahrzeugs durchgeführt werden. Checking whether a vehicle is driving directly behind the vehicle in front can alternatively or additionally can also be carried out by a test facility of the vehicle in front.

The data signal contains location information S (t2) (for example in the form of a route specification) of the rail vehicle 20, which the vehicle has determined after leaving the route section 30 at a location determination time. Furthermore, the data signal D contains a location information indicating the location determination time, vehicle-side time indication t2 and a speed indicator V indicating the speed of the rail vehicle 20. The location information S (t2) can be formed, for example, on the basis of information which is generated when a balise passes 60 are received; alternatively, the formation of the location information can also be based on another location method, for example a satellite location such as GPS.
Die Zentraleinrichtung 50 errechnet nun auf der Basis der vom Schienenfahrzeug 20 übermittelten Daten den tatsächlichen Ort, beispielsweise in Form einer Wegstreckenangabe S' (tl), des Fahrzeugendes des Schienenfahrzeugs 20 zum Zeitpunkt des Freiwerdens des Streckenabschnitts gemäß der Zeitangabe tl, vorzugsweise gemäß The central device 50 now calculates the actual location of the vehicle end of the rail vehicle 20 at the time of the vehicle end based on the data transmitted by the rail vehicle 20, for example in the form of a route specification S '(tl) The route section becomes free according to the time t1, preferably according to
S' (tl) = S (t2 ) - V(t2-tl) S '(tl) = S (t2) - V (t2-tl)
In der Figur 3 ist das Schienenfahrzeug 20 bei der errechne- ten Position S' (tl) gestrichelt dargestellt. In FIG. 3, the rail vehicle 20 is shown in dashed lines at the calculated position S '(tl).
Folgt dem Schienenfahrzeug 20 kein hinterherfahrendes Schie nenfahrzeug, wie dies in der Darstellung gemäß den Figuren 1 bis 3 der Fall ist, so wird die Wegstreckenangabe S' (tl) zu mindest näherungsweise dem Ort des Abschnittsendes 31 des Streckenabschnitts 30 entsprechen. Es gilt also If the rail vehicle 20 is not followed by a traveling rail vehicle, as is the case in the illustration according to FIGS. 1 to 3, the route specification S '(tl) will correspond at least approximately to the location of the section end 31 of the section 30. So it applies
S ' (tl) ~ S31 wobei S31 den Ort des Abschnittsendes 31 des Streckenab schnitts 30 beispielsweise in Form einer Wegstreckenangabe bezeichnet . S '(tl) ~ S31 where S31 denotes the location of the section end 31 of the route section 30, for example in the form of a route specification.
Die Zentraleinrichtung 50 prüft nun, ob die folgende Bedin gung erfüllt ist: The central device 50 now checks whether the following condition is fulfilled:
I A | < d I A | <d
mit A = S ' (tl) - S31 wobei d eine Mindestlänge angibt, die auf der Fahrstrecke 10 fahrende Schienenfahrzeuge stets aufweisen, und A den Abstand zwischen dem Abschnittsende 31 und dem tatsächlichen Ort des Fahrzeugendes des Schienenfahrzeugs 20 zum Zeitpunkt tl be zeichnet . with A = S '(tl) - S31 where d specifies a minimum length that rail vehicles traveling on the route 10 always have, and A denotes the distance between the section end 31 and the actual location of the vehicle end of the rail vehicle 20 at time tl.
Ist die Bedingung erfüllt, so passt anschaulich beschrieben kein Schienenfahrzeug in den Bereich zwischen Abschnittsende 31 und Fahrzeugende des Schienenfahrzeugs 20. Demgemäß wird die Zentraleinrichtung 50 ein Ausgangssignal El erzeugen, das anzeigt, dass dem Schienenfahrzeug 20 kein anderes Schienen fahrzeug unmittelbar folgt. Die Figur 4 zeigt zum Vergleich die Situation für den Fall, dass dem Schienenfahrzeug 20, nachfolgend vorausfahrendes Schienenfahrzeug genannt, ein unmittelbar hinterherfahrendes Schienenfahrzeug 21 folgt. In diesem Fall wird das Freimel dungssignal F(tl') zu einem späteren Zeitpunkt erzeugt, näm lich erst dann, wenn das hinterherfahrende Schienenfahrzeug 21 den Streckenabschnitt 30 verlässt. Aus diesem Grunde ist die Differenz zwischen den Zeitangaben t2 und tl' viel klei ner als die Differenz zwischen den Zeitangaben t2 und tl, so dass nun gilt: If the condition is met, no rail vehicle fits descriptively described in the area between section end 31 and vehicle end of the rail vehicle 20. Accordingly, the central device 50 will generate an output signal El, which indicates that the rail vehicle 20 is not immediately followed by another rail vehicle. For comparison, FIG. 4 shows the situation in the event that the rail vehicle 20, hereinafter referred to as the preceding rail vehicle, is followed by a rail vehicle 21 immediately following it. In this case, the release signal F (tl ') is generated at a later point in time, namely only when the traveling rail vehicle 21 leaves the route section 30. For this reason, the difference between the times t2 and tl 'is much smaller than the difference between the times t2 and tl, so that the following now applies:
A = S ' (tl ' ) - S31 > d A = S '(tl') - S31> d
Stellt die Zentraleinrichtung 50 fest, dass die letztgenannte Bedingung erfüllt ist, so erzeugt sie ein Erkennungssignal E2, das das unmittelbar hinterherfahrende Schienenfahrzeug 21 anzeigt . If the central device 50 determines that the latter condition is fulfilled, it generates a recognition signal E2 which indicates the rail vehicle 21 traveling immediately behind.
Bei dem Ausführungsbeispielen gemäß den Figuren 1 bis 4 wird das Erzeugen des Ausgangssignals El und des Erkennungssignals E2 durch die Zentraleinrichtung 50 durchgeführt. Alternativ oder zusätzlich kann auch eine fahrzeugseitige Prüfeinrich tung des Schienenfahrzeugs 20 das Ausgangssignal El und das Erkennungssignal E2 erzeugen, wenn der fahrzeugseitigen Prü feinrichtung die Zeitangabe tl bzw. tl ' , also der Zeitpunkt des Freiwerdens des Streckenabschnitts 30 mitgeteilt wird. In the exemplary embodiments according to FIGS. 1 to 4, the generation of the output signal E1 and the detection signal E2 is carried out by the central device 50. As an alternative or in addition, a vehicle-side test device of the rail vehicle 20 can generate the output signal E1 and the detection signal E2 if the vehicle-side test device is informed of the time t1 or tl ', that is to say the time when the route section 30 becomes free.
Die Figur 5 zeigt ein Ausführungsbeispiel für eine Prüfein richtung 100 zum Erkennen eines einem vorausfahrenden Schie nenfahrzeug 20 in dem Streckenabschnitt 30 unmittelbar hin terherfahrenden Schienenfahrzeugs 21. FIG. 5 shows an exemplary embodiment of a test device 100 for recognizing a rail vehicle 20 traveling directly in front of a rail vehicle 20 in the route section 30.
Die Prüfeinrichtung 100 umfasst einen Rechner 110 und einen Speicher 120, in dem ein Betriebsprogramm BP gespeichert ist. Das Betriebsprogramm BP veranlasst bei Ausführung durch den Rechner 100 diesen dazu, unter Heranziehung der den Zeitpunkt des Freiwerdens des Streckenabschnitts 30 angebenden, stre- ckenseitigen Zeitangabe tl bzw. tl ' , der Ortsinformation S(t2) des vorausfahrenden Schienenfahrzeugs 20, der den Orts ermittlungszeitpunkt angebenden, fahrzeugseitigen Zeitangabe t2 und der die Geschwindigkeit des vorausfahrenden Schienen fahrzeugs 20 angebenden Geschwindigkeitsangabe V den Ort des Fahrzeugendes des vorausfahrenden Schienenfahrzeugs 20 zum Zeitpunkt des Freiwerdens des Streckenabschnitts 30 zu er rechnen. Anschließend ermittelt der Rechner 110 den Abstand A zwischen dem Abschnittsende 31 des Streckenabschnitts 30 und dem errechneten Ort des Fahrzeugendes und prüft anhand des Abstands A, ob dem vorausfahrenden Schienenfahrzeug 20 ein Schienenfahrzeug 21 unmittelbar hinterherfährt. Der Abstand A wird vorzugsweise ermittelt gemäß: The test device 100 comprises a computer 110 and a memory 120, in which an operating program BP is stored. The operating program BP, when executed by the computer 100, causes the computer 100 to use the data that is required to indicate the point in time when the route section 30 becomes free. corner-side time indication tl or tl ', the location information S (t2) of the preceding rail vehicle 20, the vehicle time indication t2 indicating the location determination time and the speed indication V indicating the speed of the preceding rail vehicle 20 the location of the vehicle end of the preceding rail vehicle 20 at the time of the release of route section 30. The computer 110 then determines the distance A between the section end 31 of the route section 30 and the calculated location of the vehicle end and uses the distance A to check whether the rail vehicle 20 traveling in front is directly followed by a rail vehicle 21. The distance A is preferably determined according to:
A = S' (tl) - S31 (siehe Figur 3) bzw. A = S '(tl) - S31 (see Figure 3) or
A = S' (tl') - S31 (siehe Figur 4)  A = S '(tl') - S31 (see Figure 4)
Ist die Bedingung Is the condition
A > d erfüllt, so wird das Erkennungssignal E2 erzeugt, das das un mittelbar hinterherfahrende Schienenfahrzeug 21 anzeigt. If A> d is met, the detection signal E2 is generated, which indicates that the rail vehicle 21 traveling directly behind.
Ist die Bedingung Is the condition
I A | < d erfüllt, so wird ein Ausgangssignal El erzeugt, das anzeigt, dass dem Schienenfahrzeug 20 kein anderes Schienenfahrzeug unmittelbar folgt. I A | <d is met, an output signal El is generated which indicates that no other rail vehicle is immediately following the rail vehicle 20.
Ist keine der beiden Bedingungen erfüllt, wird vorzugsweise ein Statussignal erzeugt, das angibt, dass keine zuverlässige Aussage bezüglich hinterherfahrender Fahrzeuge getroffen wer den kann. Obwohl die Erfindung im Detail durch bevorzugte Ausführungs beispiele näher illustriert und beschrieben wurde, so ist die Erfindung nicht durch die offenbarten Beispiele eingeschränkt und andere Variationen können vom Fachmann hieraus abgeleitet werden, ohne den Schutzumfang der Erfindung zu verlassen. If neither of the two conditions is met, a status signal is preferably generated which indicates that no reliable statement can be made regarding vehicles traveling behind. Although the invention has been illustrated and described in detail by means of preferred exemplary embodiments, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by a person skilled in the art without departing from the scope of the invention.
