Description

Die Erfindung betrifft ein Verfahren zur Erhöhung der Verfügbarkeit einer Gleisfreimeldeanlage, die mit einem Stellwerk verbunden ist, wobei zwischen Achszählpunkten Gleisfreimeldeabschnitte gebildet werden, sowie eine diesbezügliche Vorrichtung.The invention relates to a method for increasing the availability of a track vacancy detection system which is connected to an interlocking, wherein track vacancy detection sections are formed between axle counting points, and a related device.

Achszähl- und Gleisfreimeldesysteme dienen der Steuerung des Bahnbetriebes und müssen, insbesondere bei stark frequentierten Bahnstrecken, sehr hohen Zuverlässigkeits- und Verfügbarkeitsanforderungen genügen. Die Sicherheit und Unfallfreiheit des Bahnbetriebes hängt entscheidend von der einwandfreien Funktion der Gleisfreimeldeanlagen ab.Axle counting and track vacancy detection systems are used to control railway operations and must meet very high reliability and availability requirements, especially on heavily frequented railway lines. The safety and freedom from accidents of railway operations depends crucially on the perfect functioning of the track vacancy detection systems.

Aus der EP 1 295 775 A1 ist eine Einrichtung zur Zugerkennung bekannt, die verschachtelte Erkennungsmittel verwendet. Die DE 10 2005 048 852 A1 beschreibt außerdem ein Verfahren zur richtungsorientierten Achszählung von Schienenfahrzeugen.From the EP 1 295 775 A1 a device for detecting trains is known which uses nested detection means. The DE 10 2005 048 852 A1 also describes a method for direction-oriented axle counting of rail vehicles.

Bei Gleisfreimeldeanlagen auf der Basis von Achszählpunkten sind zwischen benachbarten Achszählpunkten Gleisfreimeldeabschnitte definiert, deren Belegungszustand durch Vergleich der Zählergebnisse der benachbarten Achszählpunkte ermittelt wird. Nachteilig bei dieser Standardkonfiguration sind vor allem die durch Störungen und Ausfälle verursachten Wirkungen. Störungen umfassen vor allem durch Umwelteinflüsse verursachte Modifikationen der Signalverläufe. Ein Ausfall ist dagegen eine permanente oder intermittierende Fehlfunktion einer Funktionseinheit, beispielsweise einer Signalverbindung. Ausfälle und Störungen führen zu betrieblichen Behinderungen. Insbesondere bei schwer zugänglichen Gleisfreimeldeabschnitten, beispielsweise in einem Tunnel, können Reparaturen nur in bestimmten Zeiträumen, zum Beispiel während der Betriebsruhe, durchgeführt werden.In the case of track vacancy detection systems based on axle counting points, track vacancy detection sections are defined between neighboring axle counting points, the occupancy status of which is determined by comparing the counting results of the neighboring axle counting points. The main disadvantage of this standard configuration is the effects caused by faults and failures. Disturbances primarily include modifications of the signal curves caused by environmental influences. A failure, on the other hand, is a permanent or intermittent malfunction of a functional unit, for example a signal connection. Failures and disruptions lead to operational disabilities. Particularly in the case of difficult-to-access track vacancy detection sections, for example in a tunnel, repairs can only be carried out at certain times, for example during the shutdown period.

Um die Verfügbarkeit bei Störungen und Ausfällen zu erhöhen, ist es bekannt, die gesamte Gleisfreimeldeanlage in doppelter Ausführung zu installieren. Dabei werden Informationen von zwei Gleisfreimeldeabschnitten an das Stellwerk übertragen. Nachteilig ist besonders, dass die Schnittstelle zum Stellwerk erweitert werden muss, damit das Stellwerk Informationen von zwei Gleisfreimeldeanlagen verarbeiten kann.In order to increase availability in the event of disruptions and failures, it is known to install the entire track vacancy detection system in duplicate. Information from two track vacancy detection sections is transmitted to the signal box. A particular disadvantage is that the interface to the signal box has to be expanded so that the signal box can process information from two track vacancy detection systems.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung oben genannter Art anzugeben, die auf einfache Weise, insbesondere ohne Erweiterung der Stellwerksschnittstelle, eine Erhöhung der Verfügbarkeit der Gleisfreimeldeanlage ermöglichen.The invention is based on the object of specifying a method and a device of the above-mentioned type which enable an increase in the availability of the track vacancy detection system in a simple manner, in particular without expanding the interlocking interface.

Verfahrensgemäß wird die Aufgabe durch das Verfahren nach Anspruch 1 gelöst.According to the method, the object is achieved by the method according to claim 1.

Die Aufgabe wird auch durch eine Vorrichtung gemäß Anspruch 5 gelöst.The object is also achieved by a device according to claim 5.

Der erste und der zweite Gleisfreimeldeabschnitt, die von Achszählpunktpaaren begrenzt werden, weisen bei korrekter Arbeitsweise der einzelnen Achszählpunkte entweder beide den Freizustand oder beide den Besetztzustand auf. Um Zustandsgleichheit oder Differenzen festzustellen, werden die ermittelten Zustände der beiden Gleisfreimeldeabschnitte in einem dritten, virtuellen Gleisfreimeldeabschnitt verarbeitet. Dieser dritte Gleisfreimeldeabschnitt verhält sich wie ein realer, achszählpunktbegrenzter Gleisfreimeldeabschnitt, indem der dritte Gleisfreimeldeabschnitt nur seinen eigenen Zustand an das Stellwerk meldet. Stellwerksseitig wird kein Unterschied zwischen einem realen und einem virtuellen Gleisfreimeldeabschnitt festgestellt. Auf diese Weise kann die Stellwerks-schnittstelle unverändert bleiben. Das Stellwerk muss nicht gleichzeitig zwei Abschnittsinformationen, nämlich die des ersten Gleisfreimeldeabschnittes und des zweiten Gleisfreimeldeabschnittes, aufwendig verarbeiten. Außerdem werden Aufwand und Kosten reduziert, da nicht mehr das gesamte Achszählsystem verdoppelt werden muss, sondern nur noch die Achszählpunkte als Achszählpunktpaare doppelt benötigt werden.If the individual axle counting points are working correctly, the first and second track vacancy detection sections, which are delimited by pairs of axle counting points, are either both in the free state or both in the occupied state. In order to determine status equality or differences, the determined statuses of the two track vacancy detection sections are processed in a third, virtual track vacancy detection section. This third track vacancy detection section behaves like a real, axle counting point limited track vacancy detection section in that the third track vacancy detection section only reports its own status to the signal box. On the signal box side, no difference is found between a real and a virtual track vacancy detection section. In this way, the interlocking interface can remain unchanged. The interlocking does not have to process two sections of information at the same time, namely that of the first track vacancy detection section and the second track vacancy detection section, in a complex manner. Also will Effort and costs are reduced, since the entire axle counting system no longer has to be duplicated, but only the axle counting points are required twice as axle counting point pairs.

Die nachfolgende Tabelle veranschaulicht die möglichen Zustände Frei, Besetzt, Gestört und Ausfall des dritten Gleisfreimeldeabschnittes in Abhängigkeit von den Zuständen Frei, Besetzt, Gestört und Ausfall des ersten und des zweiten Gleisfreimeldeabschnittes sowie resultierende Redundanz-Fehlermeldungen. Meldung an das Stellwerk Zustand erster Gleisfreimeldeabschnitt Zustand zweiter Gleisfreimeldeabschnitt Zustand dritter Gleisfreimeldeabschnitt Redundanz vorhanden Frei Frei Frei Ja Frei Besetzt Frei Ja Besetzt Frei Frei Ja Besetzt Besetzt Besetzt Ja Gestört Gestört Gestört Nein Gestört Frei Frei Nein Gestört Besetzt Besetzt Nein Ausfall Frei Frei Nein Ausfall Besetzt Besetzt Nein Frei Ausfall Frei Nein Besetzt Ausfall Besetzt Nein Ausfall Ausfall Ausfall Nein The table below illustrates the possible statuses of free, occupied, faulty and failure of the third track vacancy detection section depending on the statuses of free, occupied, faulty and failure of the first and second track vacancy detection sections as well as the resulting redundancy error messages. Message to the signal box Condition of the first track vacancy detection section Condition of second track vacancy detection section Condition of the third track vacancy detection section redundancy available Free Free Free Yes Free Occupied Free Yes Occupied Free Free Yes Occupied Occupied Occupied Yes Disturbed Disturbed Disturbed No Disturbed Free Free No Disturbed Occupied Occupied No failure Free Free No failure Occupied Occupied No Free failure Free No Occupied failure Occupied No failure failure failure No

Dabei ist gemäß Anspruch 2 vorgesehen, dass der dritte, virtuelle Gleisfreimeldeabschnitt bei Frei-Zustand des ersten oder des zweiten Gleisfreimeldeabschnittes und Besetzt-Zustand des jeweils anderen dieser beiden Gleisfreimeldeabschnitte seinen Frei-Zustand und den Besetzt-Zustand des ersten oder des zweiten Gleisfreimeldeabschnittes an das Stellwerk meldet und das stellwerksseitig eine Grundstellbedienung des im Besetzt-Zustand befindlichen ersten oder zweiten Gleisfreimeldeabschnittes erfolgt. Auf diese Weise ist die Funktionalität der Freimeldung weiterhin gegeben, wenn entweder der erste Gleisfreimeldeabschnitt oder der zweite Gleisfreimeldeabschnitt Besetzt feststellt. Dieser Besetzt gebliebene Gleisfreimeldeabschnitt wird in die Grundstellung freigeschaltet. Die Verfügbarkeit wird somit nicht beeinträchtigt.According to claim 2, it is provided that the third, virtual track vacancy detection section transmits its free status and the occupied status of the first or second track vacancy detection section to the Interlocking reports and the interlocking side a basic setting operation of the first or second in the occupied state Track vacancy detection section takes place. In this way, the functionality of the vacancy detection continues to exist when either the first track vacancy detection section or the second track vacancy detection section detects occupancy. This track vacancy detection section that has remained occupied is activated in the basic position. The availability is therefore not affected.

Alternativ zum vorgenannten Grundstellverfahren ist gemäß Anspruch 3 vorgesehen, dass der der dritte, virtuelle Gleisfreimeldeabschnitt bei Frei-Zustand des ersten oder des zweiten Gleisfreimeldeabschnittes und Besetzt-Zustand des jeweils anderen dieser beiden Gleisfreimeldeabschnitte seinen Frei-Zustand an das Stellwerk meldet und dass der dritte Gleisfreimeldeabschnitt den im Besetzt-Zustand befindlichen ersten oder zweiten Gleisfreimeldeabschnitt in Grundstellung schaltet. Das Stellwerk bekommt dann nur genau einen Gleisfreimeldeabschnittszustand übermittelt, nämlich den verarbeiteten Gesamtzustand des dritten, virtuellen Gleisfreimeldeabschnitts. Die Grundstellung des im Besetzt-Zustand gebliebenen realen ersten oder zweiten Gleisfreimeldeabschnitts führt der dritte, virtuelle Gleisfreimeldeabschnitt selbst durch.As an alternative to the aforementioned reset method, it is provided according to claim 3 that the third, virtual track vacancy detection section reports its free status to the interlocking when the first or second track vacancy detection section is vacant and the other of these two track vacancy detection sections is occupied, and that the third track vacancy detection section switches the first or second track vacancy detection section that is in the occupied state to the basic position. The signal box then only receives exactly one track vacancy detection section status, namely the processed overall status of the third, virtual track vacancy detection section. The initial position of the real first or second track vacancy detection section that has remained in the occupied state is carried out by the third, virtual track vacancy detection section itself.

Erst bei Gestört- oder Ausfall-Zustand des ersten und/oder des zweiten Gleisfreimeldeabschnittes meldet der dritte, virtuelle Gleisfreimeldeabschnitt gemäß Anspruch 4 einen Redundanz-Fehlerzustand als Diagnosemeldung.Only when the first and/or the second track vacancy detection section is in a faulty or failed state does the third, virtual track vacancy detection section report a redundancy error status as a diagnostic message.

Vorzugsweise sind die Achszählpunktpaare gemäß Anspruch 6 jeweils in einem gleichen Bahnschwellenfach angeordnet. Die einzelnen Achszählpunkte, die ein Achszählpunktpaar bilden, sind innerhalb des Schwellenfaches genau gegenüber in der Weise angeordnet, dass die Gleisfreimeldeabschnittslängen und -grenzen des ersten und des zweiten Gleisfreimeldeabschnittes exakt übereinstimmen. Somit ist gewährleistet, dass bei korrekter Arbeitsweise der Achszählpunkte beide Gleisfreimeldeabschnitte entweder den Zustand Frei oder den Zustand Besetzt an den Abschnittsrechner des dritten Gleisfreimeldeabschnittes übermitteln.According to claim 6, the pairs of axle counting points are preferably each arranged in the same railroad tie compartment. The individual axle counting points, which form a pair of axle counting points, are arranged exactly opposite one another within the sleeper compartment in such a way that the track vacancy detection section lengths and boundaries of the first and second track vacancy detection sections match exactly. This ensures that when the axle counting points work correctly, both track vacancy detection sections either have the status free or the status occupied to the section computer of the third track vacancy detection section.

Um systematische Fehler, beispielsweise bei der Projektierung der Achszählpunktrechner, zu vermeiden, ist gemäß Anspruch 7 vorgesehen, dass die beiden Achszählpunkte des Achszählpunktpaares diversitäre Hardware und/oder Software aufweisen. Die zur Raderfassung verwendeten Komponenten, nämlich die Achszählpunkte, können von sehr unterschiedlichem Typ, aber zwecks Vereinfachung auch identisch sein.In order to avoid systematic errors, for example when configuring the axle counting point computer, it is provided according to claim 7 that the two axle counting points of the axle counting point pair have diverse hardware and/or software. The components used for wheel detection, namely the axle counting points, can be of very different types, but for the sake of simplicity they can also be identical.

Zur Vereinfachung kann nach Anspruch 8 auch vorgesehen sein, dass eines der den ersten und den zweiten Gleisfreimeldeabschnitt begrenzenden Achszählpunktpaare als Einzelachszählpunkt mit Doppelnutzungsfunktion ausgebildet ist. Damit ist die Auswerteeinheit der Achszählung in einem Gleisanschlussgehäuse nur einmal vorhanden. Ein Ausfall dieser Auswerteeinheit ist jedoch derart unwahrscheinlich, dass die Verfügbarkeit des Gesamtsystems dadurch nur sehr geringfügig eingeschränkt wird.For simplification, it can also be provided according to claim 8 that one of the axle counting point pairs delimiting the first and the second track vacancy detection section is designed as a single axle counting point with a dual-use function. This means that there is only one axle counting evaluation unit in a siding housing. However, a failure of this evaluation unit is so improbable that the availability of the overall system is only very slightly restricted as a result.

Nachfolgend wird die Erfindung anhand einer figürlichen Darstellung näher erläutert. Die Figur zeigt die wesentlichen Komponenten einer Vorrichtung zur Erhöhung der Verfügbarkeit einer Gleisfreimeldeanlage.The invention is explained in more detail below using a figurative representation. The figure shows the essential components of a device for increasing the availability of a track vacancy detection system.

Es ist ersichtlich, dass ein erster Gleisfreimeldeabschnitt 1a durch zwei Zählpunkte 2a und 3a gebildet wird. Ein zweiter Gleisfreimeldeabschnitt 1b wird von Achszählpunkten 2b und 3b begrenzt, wobei die beiden Gleisfreimeldeabschnitte 1a und 1b längen- und begrenzungsmäßig exakt übereinstimmen. Dazu bilden die Achszählpunkte 2a und 2b sowie 3a und 3b jeweils Achszählpunktpaare 2a/2b und 3a/3b, welche im gleichen Schwellenfach 4a beziehungsweise 4b eines Gleises 5 angeordnet sind. Eine Auswerteeinheit 6a ermittelt aus den Achszählergebnissen der Achszählpunkte 2a und 3a den Zustand Frei, Besetzt, Gestört oder Ausfall des ersten Gleisfreimeldeabschnittes 1a. Analog verarbeitet eine zweite Auswerteeinheit 6b die Zählergebnisse der Achszählpunkte 2b und 3b. Die Zustandsinformationen der beiden Auswerteeinheiten 6a und 6b werden einem Achszählrechner 7 zugeführt, der diese Zustandsinformationen verarbeitet. Die verarbeitete Zustandsinformation wird an ein Stellwerk 8 als Zustand eines dritten, virtuellen Gleisfreimeldeabschnittes weitergeleitet. Das Stellwerk 8 empfängt somit nur Zustandsinformationen der üblichen Art. Dass es sich nicht um die tatsächlich festgestellten Zustände in den Auswerteeinheiten 6a und 6b handelt, ist stellwerksseitig nicht bekannt. Die Schnittstelle zum Stellwerk 8 muss folglich nicht für doppelte Zustandsmeldungen neu konzipiert werden.It can be seen that a first track vacancy detection section 1a is formed by two counting points 2a and 3a. A second track vacancy detection section 1b is delimited by axle counting points 2b and 3b, with the two track vacancy detection sections 1a and 1b exactly matching in terms of length and limitation. For this purpose, the axle counting points 2a and 2b as well as 3a and 3b each form axle counting point pairs 2a/2b and 3a/3b, which are arranged in the same sleeper compartment 4a or 4b of a track 5. An evaluation unit 6a determines from the axle counting results of the axle counting points 2a and 3a the status free, occupied, disturbed or failure of the first track vacancy reporting section 1a. A second evaluation unit processes in the same way 6b the counting results of the axle counting points 2b and 3b. The status information from the two evaluation units 6a and 6b is fed to an axle counting computer 7, which processes this status information. The processed status information is forwarded to an interlocking 8 as the status of a third, virtual track vacancy detection section. The interlocking 8 thus only receives status information of the usual type. Consequently, the interface to the signal box 8 does not have to be redesigned for double status reports.

Die von dem Achszählrechner 7 an das Stellwerk 8 übermittelten Meldungen ergeben sich aus obiger Tabelle. Unkritisch ist eine Zustandsmeldung des Achszählrechners 7 bezüglich des dritten, virtuellen Gleisfreimeldeabschnittes, so lange keiner der realen Gleisfreimeldeabschnitte 1a oder 1b den Zustand Gestört oder Ausfall aufweist. Dann wird davon ausgegangen, dass Redundanz vorhanden ist. Das gilt auch für den Fall, dass einer der beiden Gleisfreimeldeabschnitte 1a oder 1b freigemeldet und der jeweils andere Gleisfreimeldeabschnitt 1b oder 1a besetztgemeldet ist. Die Verarbeitung durch den Achszählrechner 7 führt zur Zustandsmeldung Frei an das Stellwerk 8 und zur Grundstellbedienung des besetztgemeldeten Gleisfreimeldeabschnittes 1a oder 1b. Die Grundstellbedienung erfolgt üblicherweise stellwerksseitig. Es ist aber auch möglich, diese Funktionalität in den stellwerksexternen Achszählrechner 7 zu verlagern.The messages transmitted from the axle counting computer 7 to the signal box 8 result from the table above. A status report from the axle counting computer 7 with regard to the third, virtual track vacancy detection section is uncritical as long as none of the real track vacancy detection sections 1a or 1b has the status faulty or failure. Then it is assumed that redundancy is present. This also applies if one of the two track vacancy detection sections 1a or 1b is reported as vacant and the other track vacancy detection section 1b or 1a is reported as occupied. The processing by the axle counting computer 7 leads to the free status message to the interlocking 8 and to the basic setting operation of the occupied track free reporting section 1a or 1b. The basic operation is usually carried out at the interlocking. However, it is also possible to relocate this functionality to the axle counting computer 7 external to the interlocking.
