Description

Die Erfindung betrifft eine Anordnung zum Testen von ETCS-Level-2-Funktionalitäten im Schienenverkehr.The invention relates to an arrangement for testing ETCS Level 2 functionalities in rail traffic.

Im europäischen Schienenverkehr wird das bekannte Zugsicherungssystem "European Train Control System, ETCS" verwendet, das als Zugbeeinflussungssystem ein grundlegender Bestandteil des zukünftigen einheitlichen europäischen Eisenbahnverkehrsleitsystems ERTMS ist. Das ETCS soll langfristig die verschiedenen Zugbeeinflussungssysteme in Europa ablösen. Diese Standardisierung ermöglicht eine starke Vereinfachung der signaltechnischen Ausrüstung der Züge in den transeuropäischen Schienennetzen sowie einen einheitlichen hohen Sicherheitsstandard der Infrastruktur. Dabei bleibt die Streckenausrüstung weiterhin unter nationaler Aufsicht.In European rail transport, the well-known train control system "European Train Control System, ETCS" is used, which, as a train control system, is a fundamental part of the future uniform European railway traffic control system ERTMS. In the long term, the ETCS is intended to replace the various train control systems in Europe. This standardization enables the signaling equipment of trains in the trans-European rail networks to be greatly simplified as well as a uniform, high safety standard for the infrastructure. The route equipment remains under national supervision.

Beim ETCS ist eine so genannte "On-Board Unit, OBU" als Baugruppe auf jedem Schienenfahrzeug vorgesehen.With ETCS, a so-called “On-Board Unit, OBU” is provided as a module on every rail vehicle.

Mit dieser OBU-Baugruppe wird die Bewegung des Schienenfahrzeugs überwacht. Im Notfall veranlasst bzw. leitet die OBU auch eine Zwangsbremsung ein. Für die Überwachung stützt sie sich auf Zugdaten, die über Eingaben des Fahrers des Schienenfahrzeugs vorbekannt sind, sowie auf Daten von der Strecke, die sie durch Balisen und im Fall von "ETCS Level 2" zusätzlich per Funk von einem "Radio-Block-Center, RBC" erhält. Sie sendet permanent Positionsdaten an das Radio-Block-Center, so dass dieses den Zuglauf verfolgen kann.This OBU assembly is used to monitor the movement of the rail vehicle. In an emergency, the OBU also initiates or initiates emergency braking. For monitoring, it relies on train data, which is previously known via inputs from the driver of the rail vehicle, as well as on data from the route, which it transmits through balises and, in the case of "ETCS Level 2", additionally via radio from a "radio block center "RBC" receives. It constantly sends position data to the radio block center so that it can track the train's progress.

Das "Radio-Block-Center, RBC" ist hier im Stellwerk angeordnet bzw. vorgesehen, um den oben genannten "ETCS-Level 2-Betrieb" zu realisieren.The "Radio Block Center, RBC" is arranged or provided here in the signal box in order to implement the above-mentioned "ETCS Level 2 operation".

Das Radio-Block-Center RBC erhält vom Stellwerk sicherungstechnische Daten einer Fahrstrecke, beispielweise Daten zur eingestellten Fahrstrecke, zu belegten Gleisabschnitten, etc.The Radio Block Center RBC receives safety data for a route from the signal box, for example data on the set route, occupied track sections, etc.

Das Radio-Block-Center RBC bestimmt daraus für jedes Schienenfahrzeug, das sich im Kontrollbereich des Stellwerks befindet, jeweils geltende Sicherheitsinformationen.From this, the Radio Block Center RBC determines the applicable safety information for each rail vehicle that is in the control area of the signal box.

Die für ein vorbestimmtes Schienenfahrzeug ermittelten Sicherheitsinformationen werden vom Radio-Block-Center RBC an die On-Board Unit OBU des zugehörigen Schienenfahrzeugs übermittelt.The safety information determined for a predetermined rail vehicle is transmitted by the radio block center RBC to the on-board unit OBU of the associated rail vehicle.

Diese Übermittlung wird unter Verwendung einer Funkverbindung, bevorzugt über das bekannte System GSM-R, durchgeführt.This transmission is carried out using a radio connection, preferably via the well-known GSM-R system.

Beim "ETCS Level 2" ist eine ständige Kommunikation zwischen Schienenfahrzeug und einer ETCS-Zentrale bzw. Stellwerk via Euroradio vorgesehen.With "ETCS Level 2" there is constant communication between the rail vehicle and an ETCS center or signal box via Euroradio.

Für einen Test von ETCS-Level-2-Funktionalitäten im Feldbetrieb wird ein Radio-Block-Center RBC benötigt, das jedoch nur für einen Regelbetrieb auf einer bestimmten Strecke vorgesehen ist.To test ETCS Level 2 functionalities in field operation, a radio block center RBC is required, but this is only intended for regular operation on a specific route.

Für Testfahrten ergeben sich damit folgende Nachteile:

  • Testfahrten sind nur auf bestimmten Strecken und zu bestimmten Zeiten möglich. In der Regel sind Voranmeldungen nötig und es werden Gebühren fällig. In manchen Projekten sind auch aufwendige Überführungen notwendig.
  • Die Kooperation mit einem Fahrdienstleiter im Stellwerk wird benötigt, die ggf. in Konkurrenz zum normalen Betrieb auf der Teststrecke steht.
  • Spezielle Funktionen (z.B. für Tunnel, neutrale Abschnitte, u.a) können nur unter realen Bedingungen getestet werden, so dass auf der Teststrecke die Anwendung dieser Funktionalitäten möglich sein muss. Dies bedingt einen erhöhten Zeitaufwand.
  • Sind die Möglichkeiten zum Testen der genannten speziellen Funktionen auf der Teststrecke nicht gegeben, ist ein Feldtest nicht durchführbar.
  • Fehler des Personals bzw. zugehörige Stresssituationen können im Feld nicht getestet werden, da das RBC nur für den regulären Betrieb vorgesehen ist und Fehlersituationen nicht zulässt.
This results in the following disadvantages for test drives:
  • Test drives are only possible on certain routes and at certain times. As a rule, advance registration is required and fees apply. In some projects, complex transfers are also necessary.
  • Cooperation with a dispatcher in the signal box is required, which may be in competition with normal operations on the test route.
  • Special functions (e.g. for tunnels, neutral sections, etc.) can only be tested under real conditions, so it must be possible to use these functionalities on the test route. This requires an increased amount of time.
  • If there are no opportunities to test the special functions mentioned on the test track, a field test cannot be carried out.
  • Personnel errors or associated stressful situations cannot be tested in the field because the RBC is only intended for regular operation and does not allow error situations.

Diese Probleme wurden bisher ausschließlich organisatorisch gelöst, indem entsprechend Zeit für Testfahrten auf offiziellen Teststrecken eingeplant wurde. Darüber hinaus wurden diejenigen Funktionen, die auf der Teststrecke nicht prüfbar waren, lediglich im Labor getestet.So far, these problems have only been solved organizationally by scheduling appropriate time for test drives on official test routes. In addition, those functions that could not be tested on the test track were only tested in the laboratory.

Aus Dokument DE 10 2018 116 919 B3 ist ein Verfahren beaknnt, bei dem eine vollständige Simulation einer Streckenfahrt eines Triebfahrzeugs erfolgt.From document DE 10 2018 116 919 B3 is a method known in which a complete simulation of a locomotive's route is carried out.

Aus Dokument CN 106 993 307 A ist eine Simulation zum Testen einer sogenannten "vehicle to ground" Kommunikation bekannt.From document CN 106 993 307 A a simulation for testing so-called "vehicle to ground" communication is known.

Es ist daher die Aufgabe der vorliegenden Erfindung, einen verbesserten Test von ETCS-Level-2-Funktionalitäten im Schienenverkehr anzugeben, der sicher und mit geringen Kosten die oben genannten Nachteile reduziert bzw. gänzlich vermeidet.It is therefore the object of the present invention to provide an improved test of ETCS Level 2 functionalities in rail transport, which safely and at low cost reduces or completely avoids the disadvantages mentioned above.

Zugleich werden über den Rechner für Testzwecke simulierte Daten gebildet und an die On-Board Unit OBU kabelgebunden übertragen.At the same time, simulated data is generated via the computer for test purposes and transmitted via cable to the on-board unit OBU.

Entsprechend werden Daten für Testzwecke von der On-Board Unit OBU kabelgebunden an den Rechner zurückübertragen.Accordingly, data for test purposes is transmitted back to the computer by cable from the on-board unit OBU.
