Description

Die Erfindung betrifft ein Verfahren zum Lokalisieren eines in einem CBTC (Communication-Based Train Control)-Zugsteuerungs- und Zugsicherungssystems verkehrenden Schienenfahrzeugs mit einer bordeigenen Zugsteuerungseinrichtung und streckenseitigen Zugsicherungseinrichtungen sowie mit einer Lokalisierungseinheit zum Erfassen von Positionswerten während der Fahrt des Schienenfahrzeugs.The invention relates to a method for locating a rail vehicle operating in a CBTC (Communication-Based Train Control) train control and train protection system with an on-board train control device and trackside train protection devices and with a localization unit for detecting position values while the rail vehicle is traveling.

Bei einem bekannten Verfahren dieser Art kennt die bordeigene, automatische Zugsteuerungseinrichtung, die auch als automatic train control (ATC) bezeichnet wird, stets die genaue Position des Schienenfahrzeugs auf der Strecke. Zu diesem Zwecke liest die bordeigene, automatische Zugsteuerungseinrichtung Referenzpunkte an der Strecke aus, die durch streckenseitige Einrichtungen, wie beispielsweise Balisen, gebildet sind. Die Position der Balisen ist dabei definiert in einer Konfigurationsdatei, die von der bordeigenen automatischen Zugsteuerungseinrichtung benutzt wird. Zur Lokalisierung eines Schienenfahrzeugs ist es in der Regel erforderlich, dass dieses zwei Referenzpunkte passieren muss, um Sicherheit über die Position und die Fahrtrichtung des Schienenfahrzeuges zu gewinnen. Um eine ständige Lokalsierung während der Fahrt des Schienenfahrzeugs - zwischen zwei Referenzpunkten - zu ermöglichen, werden in bekannter Weise Sensoren, wie beispielsweise Radar-Einrichtungen oder Odometer verwendet. Mit diesen Anordnungen wird die jeweilige Geschwindigkeit und die jeweilige Position des Schienenfahrzeugs bestimmt.In a known method of this type, the on-board automatic train control device, which is also referred to as automatic train control (ATC), always knows the exact position of the rail vehicle on the route. For this purpose, the on-board, automatic train control device reads reference points on the route, which are formed by route-side devices, such as balises. The position of the balises is defined in a configuration file that is used by the on-board automatic train control device. To locate a rail vehicle, it is usually necessary for it to pass two reference points in order to gain certainty about the position and the direction of travel of the rail vehicle. To enable permanent localization while the rail vehicle is traveling - between two reference points - sensors, such as radar devices or odometers, are used in a known manner. With these arrangements, the respective speed and the respective position of the rail vehicle is determined.

Bei der Durchführung des bekannten Verfahrens kann der Fall eintreten, dass das Schienenfahrzeug delokalisiert wird, weil beispielsweise ein Odometer versagt hat oder Balisen fehlerhaft gearbeitet haben. In diesem Falle entstehen Sicherheitsrisiken, weil der Zugführer die Verantwortlichkeit übernehmen muss, bis das CBTC-Zugsteuerungs- und Zugsicherungssystem wieder in Ordnung ist bzw. eine Lokalisierung erfolgt ist. Bei führerlosen Schienenfahrzeugen muss der Operator die Verantwortlichkeit für die Weiterfahrt des Schienenfahrzeugs übernehmen.When the known method is carried out, it can happen that the rail vehicle is delocalized because, for example, an odometer has failed or balises are defective have worked. In this case, safety risks arise because the train driver must assume responsibility until the CBTC train control and train protection system is in order again or localization has taken place. In the case of driverless rail vehicles, the operator must assume responsibility for the continued journey of the rail vehicle.

Es besteht nun zur optimalen Abwicklung des Schienenfahrzeug-Verkehrs in einem CBTC-Zugsteuerungs- und Zugsicherungssystems Bedarf, möglichst schnell im Falle einer Delokalisierung wieder eine Lokalisierung des Schienenfahrzeugs zu erreichen. Deshalb könnte man daran denken, die streckenseitigen Einrichtungen, wie zum Beispiel die Balisen, in kürzeren Abständen anzuordnen, um möglichst alsbald nach einer Delokalisierung wieder eine Lokalisierung zu erreichen. Auch ließe sich bei einer Ausfahrt eines Schienenfahrzeugs aus einem Depot eine Lokalisierung schneller erreichen, wenn bis zum Übergang des Zuges in die Hauptstrecke auf der Depotzufahrtsstrecke mehrere Balisen angeordnet werden.For optimal handling of rail vehicle traffic in a CBTC train control and train protection system, there is now a need to re-locate the rail vehicle as quickly as possible in the event of delocalization. Therefore, one could think of arranging the trackside facilities, such as the balises, at shorter intervals in order to achieve localization again as soon as possible after delocalization. Localization could also be achieved more quickly when a rail vehicle exited a depot if several balises were arranged on the depot access route until the train passed into the main route.

Aus der Druckschrift WO 2014/048710 A2 ist ein Verfahren zum Orten eines Schienenfahrzeugs bekannt. Dabei grenzen zwei Streckenabschnitte aneinander, von denen jeder Streckenabschnitt jeweils durch eine äußere Achszähl-Sensoreinheit und an ihrer gemeinsamen Grenze durch eine gemeinsame Achszähl-Sensoreinheit begrenzt wird. Die Achszähl-Sensoreinheiten eines Streckenabschnitts sind mit einer dem Streckenabschnitt zugeordneten jeweiligen Achszähl-Auswerteeinrichtung verbunden. Wenn sich ein Schienenfahrzeug über die äußere Achszähl-Sensoreinheit in den ersten Streckenabschnitt hinein bewegt, wird die Anzahl der Achsen des Schienenfahrzeugs über die äußere Achszähl-Sensoreinheit bestimmt.From the publication WO 2014/048710 A2 a method for locating a rail vehicle is known. In this case, two route sections adjoin one another, each route section being delimited by an outer axle count sensor unit and at their common limit by a common axle count sensor unit. The axle count sensor units of a route section are connected to a respective axle count evaluation device assigned to the route section. When a rail vehicle moves into the first route section via the outer axle count sensor unit, the number of axles of the rail vehicle is determined via the outer axle count sensor unit.

Gleiches erfolgt, wenn sich das Schienenfahrzeug über die gemeinsame Achszähl-Sensoreinheit in den zweiten Streckenabschnitt hinein bewegt. Dann wird zu einem Zeitpunkt T die Anzahl der Achsen, die sich (noch) im ersten Streckenabschnitt befinden detektiert und es wird zum Zeitpunkt T auch der Moment ermittelt, an dem die erste Achse des Schienenfahrzeugs aus dem ersten Streckenabschnitt in den zweiten Streckenabschnitt wechselt. Über die vorbekannte Position der gemeinsamen Achszähl-Sensoreinheit wird dann die Position der ersten Achse und dadurch die Position der Schienenfahrzeugs ermittelt.The same happens when the rail vehicle moves into the second route section via the common axle counting sensor unit. The number of axles that are (still) in the first route section is then detected at a time T and the moment at which the first axle of the rail vehicle changes from the first route section to the second route section is also determined at time T. The position of the first axle and thereby the position of the rail vehicle is then determined via the previously known position of the common axle counting sensor unit.

Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren der eingangs angegebenen Art so auszugestalten, dass mit ihm eine schnelle Lokalisierung eines Schienenfahrzeugs mit vergleichsweise geringem Aufwand durchgeführt werden kann.The invention is based on the object of designing a method of the type specified at the outset in such a way that it can be used to quickly locate a rail vehicle with comparatively little effort.

Die Aufgabe wird mit einem Verfahren nach Anspruch 1 und einer Anordnung nach Anspruch 4 gelöst.The object is achieved with a method according to claim 1 and an arrangement according to claim 4.

Zur Lösung dieser Aufgabe wird bei einem Verfahren zum Lokalisieren eines in einem CBTC-Zugsteuerungs- und Zugsicherungssystems verkehrenden Schienenfahrzeugs mittels der Lokalisierungseinheit mit einem in einer Position des Schienenfahrzeugs gespeicherten, zuverlässigen Positionswert und einem empfangenen Positionswert eines bei der Fahrt des Schienenfahrzeugs nächst folgend passierten Referenzpunktes eine Lokalisierung des Schienenfahrzeugs vorgenommen wird.To achieve this object, in a method for locating a rail vehicle running in a CBTC train control and train protection system by means of the localization unit with a reliable position value stored in a position of the rail vehicle and a received position value of a reference point that follows next when the rail vehicle is traveling Localization of the rail vehicle is made.

Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens besteht darin, dass mit ihm ein delokalisiertes Schienenfahrzeug vergleichsweise schnell wieder lokalisiert werden kann, weil es nur der Fahrt bis zu einem nächstfolgenden Referenzpunktes bedarf, um eine Lokalisierung zu erreichen; dies ist in einfacher Weise dadurch bewirkt, dass neben dem empfangenen Positionswert des nächstfolgend passierten Referenzpunktes ein vorher gespeicherter, zuverlässiger Positionswert herangezogen wird. Das Schienenfahrzeug muss bei dem erfindungsgemäßen Verfahren nicht erst zwei Referenzpunkte beziehungsweise Balisen wie bei dem bekannten Verfahren passieren, um lokalisiert beziehungsweise nach einer Delokalisierung wieder lokalisiert zu werden, weil anstelle der einen Balise der gespeicherte Positionswert benutzt wird; nur die zweite Balise ist also noch erforderlich.A major advantage of the method according to the invention is that it can be used to locate a delocalized rail vehicle again relatively quickly, because it only takes a trip to a next reference point to achieve localization; this is achieved in a simple manner in that, in addition to the received position value of the reference point that is passed next, a previously stored, reliable position value is used. In the method according to the invention, the rail vehicle does not first have to pass two reference points or balises as in the known method in order to be localized or to be localized again after delocalization, because the stored position value is used instead of the one balise; only the second balise is therefore still required.

Dabei ist das erfindungsgemäße Verfahren mit Vorteil auch dann einzusetzen, wenn das Schienenfahrzeug aus einem Depot hinaus auf dem Weg zur Hauptstrecke ist, weil als gespeicherter, zuverlässiger Positionswert der Startpunkt des Schienenfahrzeugs im Depot verwendet werden kann und dann nur noch ein weiterer Referenzpunkt passiert werden muss, um eine Lokalisierung des Schienenfahrzeugs zu bewirken.The method according to the invention can also be used with advantage when the rail vehicle is on its way to the main route from a depot because the starting point of the rail vehicle in the depot can be used as a stored, reliable position value and then only a further reference point has to be passed to locate the rail vehicle.

Das erfindungsgemäße Verfahren lässt sich auch dann einsetzen, wenn eine Delokalisierung während seiner Fahrt auf der Strecke eingetreten ist. In diesem Fall werden nämlich mittels der Lokalisierungseinheit während der Fahrt des Schienenfahrzeugs zuverlässige Positionswerte der Lokalisierungseinheit erkannt und gespeichert und ein vor dem Auftreten von unzuverlässigen Positionswerten zuletzt gespeicherter Positionswert wird als der gespeicherte, zuverlässige Positionswert verwendet. Auch hier lässt sich bei einer Delokalisierung relativ schnell eine Lokalisierung erneut erreichen, weil nur noch ein nächstfolgender Referenzpunkt an der Strecke nach Auftreten der Delokalisierung passiert werden muss.The method according to the invention can also be used if delocalization has occurred while driving on the route. In this case, the localization unit detects and stores reliable position values of the localization unit while the rail vehicle is traveling, and a position value last saved before the occurrence of unreliable position values is used as the stored, reliable position value. Here, too, a localization can be achieved again relatively quickly in the case of delocalization, because only a next reference point on the route has to be passed after the delocalization has occurred.

Die zuverlässigen Positionswerte können nach ihrer Erfassung in unterschiedlicher Weise gespeichert werden; als vorteilhaft wird es angesehen, wenn diese Positionswerte in der bordeigenen Zugsteuerung gespeichert werden. Es ist aber auch möglich und unter Umständen auch vorteilhaft, wenn die zuverlässigen Positionswerte in der streckenseitigen Zugsteuerung gespeichert werden.The reliable position values can be stored in different ways after they have been recorded; It is considered advantageous if these position values in the on-board train control can be saved. However, it is also possible and possibly also advantageous if the reliable position values are stored in the train control on the track side.

Die Erfindung bezieht sich ferner auf eine Anordnung zum Lokalisieren eines in einem CBTC (Communication-Based Train Control)-Zugsteuerungs- und Zugsicherungssystems verkehrenden Schienenfahrzeugs mit einer bordeigenen Zugsteuerungseinrichtung und streckenseitigen Zugsicherungseinrichtungen sowie mit einer Lokalisierungseinheit zum Erfassen von Positionswerten während der Fahrt des Schienenfahrzeugs.The invention further relates to an arrangement for locating a rail vehicle running in a CBTC (Communication-Based Train Control) train control and train protection system with an on-board train control device and trackside train protection devices and with a localization unit for detecting position values while the rail vehicle is traveling.

Um mit einer solchen Anordnung mit vergleichsweise geringem Aufwand und schnell eine Lokalisierung eines delokalisierten Schienenfahrzeugs zu erreichen, ist erfindungsgemäß mittels der Lokalisierungseinheit mit einem in einer Position des Schienenfahrzeugs gespeicherten, zuverlässigen Positionswert und einem empfangenen Positionswert eines bei der Fahrt des Schienenfahrzeugs nächst folgend passierten Referenzpunktes eine Lokalisierung des Schienenfahrzeugs vorgenommen.In order to achieve a localization of a delocalized rail vehicle quickly and with such an arrangement with comparatively little effort, the location unit according to the invention provides a reliable position value stored in a position of the rail vehicle and a received position value of a reference point that is passed next when the rail vehicle is traveling Localization of the rail vehicle made.

Mit dem erfindungsgemäßen Verfahren ergeben sich sinngemäß die gleichen Vorteile, wie sie oben zum erfindungsgemäßen Verfahren aufgeführt worden sind.The method according to the invention gives the same advantages as have been listed above for the method according to the invention.

Bei der erfindungsgemäßen Anordnung ist die Lokalisierungseinheit geeignet, während der Fahrt des Schienenfahrzeugs zuverlässige Positionswerte der Lokalisierungseinheit zu erkennen und zu speichern und einen vor dem Auftreten von unzuverlässigen Positionswerten zuletzt gespeicherten Positionswert als den gespeicherten, zuverlässigen Positionswert zu verwenden. Dadurch ist auch hier die Möglichkeit gegeben, auf der Strecke schnell und mit geringem Aufwand eine Lokalisierung wieder vorzunehmen, nachdem das Schienenfahrzeug delokalisiert worden ist.In the arrangement according to the invention, the localization unit is suitable for recognizing and storing reliable position values of the localization unit while the rail vehicle is traveling, and for using a position value last saved before the occurrence of unreliable position values as the stored, reliable position value. As a result, it is also possible here to locate the route again quickly and with little effort after the rail vehicle has been delocalized.

Die Figuren 1 bis 4 zeigen eine Gleisanordnung 1, die eine Strecke 2 mit einer nur schematisch dargestellten Weiche 3 aufweist, von der geradeaus eine Strecke 4 und abgezweigt eine weitere Strecke 5 fortführen. Hinter der Weiche 3 befinden sich an der weiteren Strecke 5 eine Balise 6 und an der einen Strecke 4 als ein Referenzpunkt eine Balise 7, der in einiger Entfernung - strichliert angedeutet - eine weitere Balise 8 folgt.The Figures 1 to 4 show a track arrangement 1, which has a route 2 with a switch 3 only shown schematically, from which a route 4 straight ahead and branched off continue a further route 5. Behind the switch 3 there is a balise 6 on the further route 5 and a balise 7 on one route 4 as a reference point, which is followed by a further balise 8 at some distance - indicated by dashed lines.

Schematisch angedeutet ist in Figur 1, dass sich ein Schienenfahrzeug 9 bereits über die Weiche 3 hinweg in Richtung des Pfeiles 10 bewegt hat und delokalisiert ist, weil die Weiche 3 nicht in ihrer Geradeaus-Position verriegelt ist, was durch einen Unterstrich 11 angedeutet ist. Das Schienenfahrzeug 3 hat dabei mit seiner Empfangseinrichtung 3a für Balisensignale bereits die eine Balise 7 passiert, ist jedoch nach wie vor delokalisiert, weil es dazu der Passage der weiteren Balise 8 bedarf, was Figur 2 zeigt. Von der Stellung in der Figur 2 ab ist das Schienenfahrzeug 9 wieder lokalisiert; der Ablauf der Lokalisierung gemäß den Figuren 1 und 2 entspricht dem derzeitigen Verfahren.Is indicated schematically in Figure 1 that a rail vehicle 9 has already moved over the switch 3 in the direction of the arrow 10 and is delocalized because the switch 3 is not locked in its straight-ahead position, which is indicated by an underscore 11. The rail vehicle 3 has already passed the one balise 7 with its receiving device 3a for balise signals, but is still delocalized because it requires the passage of the further balise 8, which Figure 2 shows. From the position in the Figure 2 the rail vehicle 9 is located again; the localization process according to the Figures 1 and 2 corresponds to the current procedure.

Die Figuren 3 und 4 zeigen, wie das erfindungsgemäße Verfahren abläuft. Hier ist wiederum angenommen, dass die Weiche 3 nicht in Geradeaus-Richtung verriegelt ist, wodurch das Schienenfahrzeug 9 auch hier delokalisiert ist. Allerdings hat hier das Schienenfahrzeug 9 entsprechend dem erfindungsgemäßen Verfahren vor der Weiche 3 noch einen letzten zuverlässigen Positionswert P1 erfasst und in einem Speicher 12 gespeichert. Passiert das Schienenfahrzeug 9 - wie die Figur 4 zeigt - nun lediglich noch die eine Balise 7, so erfolgt hierbei bereits unter Heranziehung des letztgespeicherten, zuverlässigen Positionswert P1 des Schienenfahrzeugs 9 eine Lokalisierung und nicht erst bei der weiteren Balise 8.The Figures 3 and 4 show how the inventive method works. Here again it is assumed that the switch 3 is not locked in the straight-ahead direction, as a result of which the rail vehicle 9 is also delocalized here. However, in accordance with the method according to the invention, the rail vehicle 9 has detected a last reliable position value P1 in front of the switch 3 and stored it in a memory 12. Passes the rail vehicle 9 - like that Figure 4 shows - now only one balise 7, a localization takes place here already using the last stored, reliable position value P1 of the rail vehicle 9 and not only with the further balise 8.
