Abstract

The invention relates to a method for locating a rail vehicle (13) with a device (15) for determining the position of a rail vehicle on a route by reading out the positions of reference marks, passed by the rail vehicle (13), along the route of the rail vehicle (13) and by evaluating the supplementary distance information. In order to be able to locate a rail vehicle with little expenditure and with comparatively high accuracy with such a method, in the case of a route with at least one route section (1) which is bounded by axle-counting sensor units (2, 3) and has an axle-counting evaluation device (6), an axle number information item (Ae1) of the axle-counting evaluation device (6) is transmitted to the device (15) for determining the position of a rail vehicle. In the device (15) for determining the position of a rail vehicle, the position of an axle of the rail vehicle (13) which corresponds to the axle number information item (Ae1) is determined using route topology data present there, and this position is used as a further reference mark.

Description

Beschreibung description
Verfahren zum Orten eines Schienenfahrzeugs Die Erfindung betrifft ein Verfahren zum Orten eines Schienenfahrzeugs mit einer Schienenfahrzeug-Positionsbestimmungseinrichtung auf einer Fahrstrecke mittels Auslesens der Positionen von vom Schienenfahrzeug passierten Referenzmarken entlang der Fahrstrecke des Schienenfahrzeugs und durch Aus- werten von ergänzenden Entfernungsangaben. The invention relates to a method for locating a rail vehicle with a rail vehicle position determination device on a driving route by reading out the positions of reference marks passed by the rail vehicle along the travel path of the rail vehicle and by evaluating additional distance indications.
Bei einem bekannten Verfahren dieser Art (W. Fenner, P. Neumann, J. Trinckauf „Bahnsicherungstechnik", 2003, Seite 83) werden als Referenzmarken Balisen verwendet sowie schienfahr- zeugseitige Odometer, mit denen ergänzende Entfernungsangaben gewonnen werden. Dabei dienen die Balisen zur Kalibrierung der Odometer. In a known method of this type (W. Fenner, P. Neumann, J. Trinckauf "Bahnsicherungstechnik", 2003, page 83), beacons are used as reference marks, as well as on-board odometers, which are used to obtain additional distance indications Calibration of the odometer.
Der Erfindung liegt die Aufgabe zugrunde, das bekannte Ver- fahren so fortzuentwickeln, dass mit geringem Aufwand einThe object of the invention is to further develop the known method in such a way that with little effort
Schienenfahrzeug mit vergleichsweise hoher Genauigkeit geortet werden kann. Rail vehicle can be located with relatively high accuracy.
Zur Lösung dieser Aufgabe wird bei einem Verfahren der oben angegebenen Art erfindungsgemäß bei einer Fahrstrecke mit mindestens einem durch Achszähl -Sensoreinheiten begrenzten Streckenabschnitt mit einer Achszähl -Auswerteeinrichtung eine Achsanzahl - Information der Achszähl -Auswerteeinrichtung zu der Schienenfahrzeug-Positionsbestimmungseinrichtung über- tragen; in der Schienenfahrzeug-Positionsbestimmungseinrichtung wird unter Benutzung dort vorhandener Streckentopo- logie-Daten die Position einer der Achsanzahl -Information entsprechenden Achse des Schienenfahrzeugs ermittelt und diese Position als eine weitere Referenzmarke verwendet. To solve this problem, according to the invention, in a method of the type specified above, an axle number - information of the axle counting - evaluation device is transmitted to the rail vehicle position determination device in a route with at least one track section bounded by axle counting sensor units with an axle counting device; in the rail vehicle position determination device, the position of an axis of the rail vehicle corresponding to the number of axles of the rail vehicle is determined using existing line topography data and this position is used as a further reference mark.
Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens wird darin gesehen, dass den auf Streckenabschnitten mit Achszähl -Sensoreinheiten vorhandenen Achszähl -Auswerteein- richtungen eine zusätzliche Funktion zugewiesen wird, indem diese im Zusammenwirken mit den Schienenfahrzeug-Positionsbestimmungseinrichtungen zur Bildung weiterer Referenzmarken zusätzlich zu den von Balisen gebildeten üblichen Referenz- marken benutzt werden. Ortungsunsicherheiten lassen sich dann insbesondere dort verringern, wo die Entfernung zwischen den Referenzmarken bzw. Balisen relativ groß ist und Streckenabschnitte mit Achszähl -Sensoreinheiten ohnehin vorhanden sind und erfindungsgemäß zur Bildung von weiteren Referenzmarken herangezogen werden. A significant advantage of the method according to the invention is seen in the fact that the axle counts present on sections of track with axle counting sensor units are an additional function is assigned by using these in conjunction with the rail vehicle positioning devices to form further reference marks in addition to the usual reference marks formed by balises. Tracking uncertainties can then be reduced in particular where the distance between the reference marks or balises is relatively large and track sections with axle counting sensor units are present anyway and are used according to the invention to form further reference marks.
Bei dem erfindungsgemäßen Verfahren kann die Achsanzahl - Information in verschiedener Weise zu der zu der Schienenfahrzeug-Positionsbestimmungseinrichtung übertragen werden. Vorteilhaft ist es, wenn die Achsanzahl - Information von der Achszähl -Auswerteeinrichtung direkt zu der Schienenfahrzeug- Positionsbestimmungseinrichtung übertragen wird, weil in diesem Falle der Übertragungsweg kurz und damit auch die Übertragungsdauer kurz ist. Die Bestimmung der Position der der Achsanzahl - Information entsprechenden Achse des Schienenfahrzeugs kann daher ohne Weiteres sehr genau erfolgen. Erfolgt die Übertragung dabei in vorteilhafter Weise über eine Funkverbindung, dann ist ein zusätzlicher Aufwand vergleichsweise gering, weil dafür auch eine in der Regel vorhandene Empfang- seinrichtung der Schienenfahrzeug-Positionsbestimmungseinrichtung mit benutzt werden kann. In the method according to the invention, the number of axles of information can be transmitted in different ways to that for the rail vehicle position determining device. It is advantageous if the number of axles - information from the axle counting -Auswerteeinrichtung is transmitted directly to the rail vehicle position determining means, because in this case the transmission path is short and thus the transmission time is short. The determination of the position of the number of axles - information corresponding axis of the rail vehicle can therefore be carried out very precisely without further notice. If the transmission takes place advantageously via a radio link, then an additional expense is relatively low, because it can also be used for a usually existing receiving device of the rail vehicle position determination device.
In dieser Hinsicht vorteilhafter ist eine Ausführungsform des erfindungsgemäßen Verfahrens, bei dem die Achsanzahl -Informa- tion von der Achszähl -Auswerteeinrichtung über eine Zugsicherungseinheit zu der Schienenfahrzeug-Positionsbestimmungseinrichtung übertragen wird. Dabei ist es vorteilhaft, wenn die Achsanzahl - Information von der Achszähl -Auswerteeinrichtung über eine Kommunikationsverbindung zu der Zugsicherungsein- heit und von dieser über eine Nachrichtenverbindung zu der Schienenfahrzeug-Positionsbestimmungseinrichtung übertragen wird. Hierbei kann nämlich auf schon vorhandene Informations- Übertragungswege zurückgegriffen werden, beispielsweise auf CBTC-Lösungen für MetroSysteme . In this respect, an embodiment of the method according to the invention in which the number of axles of information is transmitted from the axle counting evaluation device to the rail vehicle position determination device via a train protection unit is more advantageous. It is advantageous if the number of axles - information from the axle counting -Auswerteeinrichtung is transmitted via a communication link to the Zugsicherungsein- unit and from this via a communication link to the rail vehicle position determination device. This can in fact be based on already existing information Transmission paths, for example to CBTC solutions for metro systems.
Um bei dieser Ausführungsform des erfindungsgemäßen Verfah- rens Ungenauigkeiten bei der Ermittlung der Position der der Achsanzahl - Information entsprechenden Achse des Schienenfahrzeugs zu vermeiden, wird vorteilhafterweise eine Zeitsynchronisation zwischen der Achszähl -Auswerteeinrichtung und der Schienenfahrzeug-Positionsbestimmungseinrichtung vorgenommen, die beispielsweise durch Zeitstempel erfolgen kann. In order to avoid inaccuracies in determining the position of the axle number information corresponding axis of the rail vehicle in this embodiment of the inventive method, advantageously a time synchronization between the axle counting -Auswerteeinrichtung and the rail vehicle position determination device is made, which can be done for example by time stamp.
Um die Position der der Achszahl -Information entsprechenden Achse und damit die Ortung des Schienenfahrzeugs besonders zuverlässig und auch genau vornehmen zu können, wird es als vorteilhaft erachtet, bei einer einem nachfolgenden Streckenabschnitt zugeordneten weiteren Achszähl -Auswerteeinrichtung von dieser weiteren Achszähl -Auswerteeinrichtung eine weitere Achsanzahl - Information zu der Schienenfahrzeug-Positionsbestimmungseinrichtung zu übertragen und in der Schienenfahr- zeug-Positionsbestimmungseinrichtung die weitere Achsanzahl - Information als redundante Achsanzahl - Information zur Bestimmung der Position der Achse zu verwenden. In order to be able to make the position of the axis corresponding to the axis number information and thus the locating of the rail vehicle particularly reliable and accurate, it is considered advantageous for a further section associated further axle counting -Auswerteinrichtung of this further axle counting -Auswerteeinrichtung another number of axles - to transmit information on the rail vehicle position determination device and to use in the rail vehicle position determination device the further number of axes - information as a redundant number of axes - information for determining the position of the axis.
Zur weiteren Erläuterung der Erfindung ist in der Figur ein Ausführungsbeispiel einer zur Durchführung des erfindungsgemäßen Verfahrens geeigneten Anordnung gezeigt . To further illustrate the invention, an embodiment of an arrangement suitable for carrying out the method according to the invention is shown in the figure.
In der Figur ist ein Streckenabschnitt 1 dargestellt, der durch eine Achszähl -Sensoreinheit 2 und eine weitere Achs- zähl -Sensoreinheit 3 begrenzt ist; an den einen Streckenabschnitt 1 schließt sich in dem dargestellten Ausführungsbeispiel ein weiterer Streckenabschnitt 4 an, der einerseits durch die weitere Achszähl-Sensoreinheit 3 und andererseits durch eine zusätzliche Achszähl-Sensoreinheit 5 bestimmt ist. Die Achszähl -Sensoreinheiten 2 und 3 sind mit einer Achszähl - Auswerteeinrichtung 6 verbunden. Die weitere Achszähl-Sensoreinheit 3 ist gemeinsam mit der zusätzlichen Achszähl -Sensor- einheit 5 an eine weitere Achszähl -Auswerteeinrichtung 8 angeschlossen . The figure shows a section 1 which is delimited by an axle counting sensor unit 2 and a further axle counting sensor unit 3; in the illustrated embodiment, a further section 4 connects to the one section 1, which is determined on the one hand by the further axle counting sensor unit 3 and on the other hand by an additional axle counting sensor unit 5. The axle counting sensor units 2 and 3 are connected to an axle counting evaluation device 6. The additional axle counting sensor unit 3 together with the additional axle counting sensor unit 5 connected to a further axle counting -Auswerteeinrichtung 8.
Den Streckenabschnitten 1 und 4 ist in dem dargestellten Aus- führungsbeispiel eine Zugsicherungseinheit 10 zugeordnet, die somit streckenseitig vorgesehen ist. Die Zugsicherungseinheit 10 ist über eine bidirektionale Kommunikationsverbindung 11 sowohl mit der einen Achszähl -Auswerteeinrichtung 6 als auch mit der weiteren Achszähl -Auswerteeinrichtung 8 verbunden. Von der einen Achszähl -Auswerteeinrichtung 6 wird eine Achsanzahl - Information Ael zur automatischen Zugsicherungseinheit 8 übertragen, wenn sich ein Schienenfahrzeug 13 in Richtung eines Pfeils 12 in den einen Streckenabschnitt 1 hineinbewegt. Befindet sich ein Schienenfahrzeug vollständig auf dem einen Streckenabschnitt 1, dann gibt diese Achsanzahl - Information Ael die Anzahl der von der einen Achszähl -Sensoreinheit 2 erfassten Anzahl von Achsen wieder. Entsprechendes gilt hinsichtlich der weiteren Achszähl -Auswerteeinrichtung 8, die eine weitere Achsanzahl -Information Ae2 an die automa- tische Zugsicherungseinheit 10 sendet, wenn in diesen Streckenabschnitt ein Schienenfahrzeug eingefahren ist. In dem dargestellten Beispiel gemäß Figur 1 wird der automatischen Zugsicherungseinheit 10 eine Achsanzahl „12" im ersten Streckenabschnitt 1 und eine Achsanzahl „0" für den Streckenab- schnitt 4 gemeldet. The track sections 1 and 4 in the illustrated embodiment, a Zugsicherungseinheit 10 is assigned, which is thus provided trackside. The train protection unit 10 is connected via a bidirectional communication link 11 both to the one axle counting evaluation device 6 and to the further axle counting evaluation device 8. An axle counting device 6 transmits an axle number information Ael to the automatic train control unit 8 when a rail vehicle 13 moves in the direction of an arrow 12 into the one track section 1. If a rail vehicle is located completely on the one track section 1, then this number of axles of information Ael represents the number of the number of axles detected by the one axle counting sensor unit 2. The same applies with regard to the further axle counting evaluation device 8 which sends a further number of axles of information Ae2 to the automatic train control unit 10 when a rail vehicle has entered this section. In the example shown in FIG. 1, the automatic train control unit 10 is notified of an axle count "12" in the first track section 1 and an axle count "0" for the track section 4.
Wie die Figur ferner zeigt, ist das Schienenfahrzeug 13 mit einer Schienenfahrzeug-Positionsbestimmungseinrichtung 15 ausgerüstet, mit der die Positionen von Zugspitze und Zugende möglichst genau bestimmt werden. In der Schienenfahrzeug- Positionsbestimmungseinrichtung 15 sind Daten des Schienenfahrzeugs 13, wie Länge, Anzahl der Achsen und die Positionen der Achsen in Bezug auf die Länge des Schienenfahrzeugs 13 gespeichert . As the figure further shows, the rail vehicle 13 is equipped with a rail vehicle position determining means 15, with which the positions of Zugspitze and Zugende are determined as accurately as possible. In the rail vehicle position determining means 15, data of the rail vehicle 13 such as length, number of axles and positions of the axles with respect to the length of the rail vehicle 13 are stored.
Werden im Rahmen der Ortung des Schienenfahrzeugs 13 bzw. der Ermittlung der Position einer der Achsanzahl - Information entsprechenden Achse des Schienenfahrzeugs 13 die Achsanzahl- Informationen Ael und Ae2 von den Achszähl -Auswerteeinrichtungen 6 und 8 zu der Zugsicherungseinheit 10 übertragen und von dieser über die Nachrichtenverbindung 15 zur Schienenfahrzeug-Positionsbestimmungseinrichtung 14 weiter geleitet, dann werden diese Informationen von der Schienenfahrzeug- Positionsbestimmungseinrichtung 15 verarbeitet. If, as part of the locating of the rail vehicle 13 or the determination of the position of an axis of the rail vehicle 13 corresponding to the number of axles, the number of axles Information Ael and Ae2 transmitted from the axle counting -Auswerteeinrichtungen 6 and 8 to the train control unit 10 and passed from the latter via the communication link 15 to the rail vehicle position determining means 14, then this information is processed by the rail vehicle position determining means 15.
Bewegt sich das Schienenfahrzeug 13 in Richtung des Pfeils 12, beeinflusst die erste Achse des Schienenfahrzeugs 13 die eine Sensoreinheit 3 zu einem angenommenen Zeitpunkt Tl. Infolgedessen ändert sich die Achsanzahl -Information Ael von "12" auf den Wert "11" . Dies geschieht ebenfalls zum Zeitpunkt Tl, weshalb diese Achsanzahl -Information wegen der vorgenommenen Zeitsynchronisierung zwischen Schienenfahrzeug- Positionsbestimmungseinrichtung 15 und der Achszähl -Auswerteeinrichtung 6 in dem dargestellten Ausführungsbeispiels mit einem Zeitstempel entsprechend dem Zeitpunkt Tl versehen wird. Praktisch gleichzeitig ändert sich die weitere Achsanzahl - Information Ae2 der Achszähl -Auswerteeinrichtung 8 von "0" auf "1" . Auch diese Information wird mit einem entsprechenden Zeitstempel versehen. When the rail vehicle 13 moves in the direction of the arrow 12, the first axis of the rail vehicle 13 influences the one sensor unit 3 at an assumed time T1. As a result, the number of axles of information Ael changes from "12" to the value "11". This is also done at time Tl, which is why this number of axes information is provided in the illustrated embodiment with a time stamp corresponding to the time Tl because of the time synchronization between rail vehicle position determination device 15 and the axle counting -Auswerteeinrichtung 6. Practically at the same time, the further number of axles - information Ae2 of the axle counting - evaluation device 8 changes from "0" to "1". This information is also provided with a corresponding time stamp.
Die geänderten Achsanzahl -Informationen Ael und Ae2 werden über die Zugsicherungseinheit 10 zur Schienenfahrzeug- Positionsbestimmungseinrichtung 15 übertragen und von dieser verarbeitet . The changed number of axles information Ael and Ae2 are transmitted via the train protection unit 10 to the rail vehicle position determination device 15 and processed by the latter.
Die Schienenfahrzeug-Positionsbestimmungseinrichtung 15 verfügt über Streckentopologie-Daten, insbesondere über Positi- onsdaten für die Sensoreinheiten 2, 3 und 5. Die Schienenfahrzeug-Positionsbestimmungseinrichtung 15 kann daher aus den übertragenen Achsanzahl -Informationen Ael und Ae2 schließen, das sich die erste Achse des Schienenfahrzeugs 13 genau an der Position des Sensors 3 befindet. Dabei dienen die zwei Achsanzahl - Information Ael und Ae2 dazu, fehlerhafte Positionsermittlungen aufzudecken und ggf. das Ermittlungsergebnis zu verwerfen; eine weitere Referenzmarke wird dann nicht erzeugt . Das erfindungsgemäße Verfahren ist keineswegs an die Positionsermittlung der ersten Achse eines Schienenfahrzeugs gebunden. Vielmehr kann auch die letzte Achse eines Schienenfahr- zeugs herangezogen oder beliebige Achsen zwischen der ersten und der letzten Achse. The rail vehicle position determination device 15 has route topology data, in particular about position data for the sensor units 2, 3 and 5. The rail vehicle position determination device 15 can therefore conclude from the transmitted number of axles information Ael and Ae2, which is the first axis of the rail vehicle 13 is located exactly at the position of the sensor 3. The two number of axes - information Ael and Ae2 serve to detect erroneous position determinations and possibly to reject the result of the determination; another reference mark will not be generated. The method according to the invention is by no means tied to the position determination of the first axis of a rail vehicle. Rather, the last axle of a rail vehicle or any axis between the first and the last axle can be used.
