Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum vollständigen Prüfung von Zugbeeinflussungseinheiten mit Zustandsdaten von Streckensignalen bei Relaisstellwerken.The present invention relates to a method and a device for the complete testing of train control units with status data of track signals at relay interlockings.
Mit der Einführung einer neuen Zugbeeinflussungstechnologie, wie z.B. ETCS, ist es je nach zugehörigem Level des Verfahrens erforderlich, an den Lichtsignalen der Sicherungsanlage zur Anzeige der Fahrberechtigung für den voraus liegenden Abschnitt des im Streckennetzes den jeweils angezeigten Begriff abzugreifen und der Telegrammaufbereitung der neuen beizustellenden Zugbeeinflussungstechnologie zuzuführen.With the introduction of a new train control technology, such as ETCS, depending on the associated level of the procedure, it is necessary to tap the light signals of the security system for displaying the driving authorization for the preceding section of the network in the route network and to supply the message processing to the new train control technology to be provided.
Diese Fahrberechtigungssignale, es sind meist Rot / Orange / Grün - Signalsysteme mit 3 Aspekten, verfügen teilweise zusätzlich über eine Anzeige für von der Streckengeschwindigkeit nach unten abweichende einzuhaltende Geschwindigkeitslimiten für den nächsten Abschnitt.These drive authorization signals, which are mostly red / orange / green - signaling systems with 3 aspects, sometimes additionally have an indication of speed limits for the next section which deviate from the line speed.
Da heute die Netze der Bahnen sehr stark genutzt und bis an die Grenzen ausgelastet werden, ist die vollständige Prüfung der Sicherungsanlagen zu Abnahmezwecken im Streckennetz nach der Installation einer neuen Zugbeeinflussungstechnologie vor deren Nutzung ein schwieriges Unterfangen. Die auf den Sicherheitslevel der neu eingebrachten Funktion abgestimmte Prüfung muss nach Kriterien durchgeführt werden, welche den Richtlinien der Zulassungsbehörden entsprechen.As rail networks are now very heavily used and pushed to their limits, the full testing of backup systems for roadside acceptance after installing a new train control technology prior to their use is a difficult undertaking. The test adapted to the safety level of the newly introduced function must be carried out according to criteria which comply with the guidelines of the approval authorities.
Das verlangt, dass alle Zustände an den für den Fahrzeugführer zu beachtenden funktionalen Elementen des Stellwerkes in der Aussenanlage einzustellen sind, in der Regel sind das Signale, deren korrekte und vollständige Übereinstimmung auf die neu installierte Zugbeeinflussungstechnologie zu prüfen und zu protokollieren ist.This requires that all states are set to be observed by the driver functional elements of the interlocking in the outdoor area, as a rule, the signals are their correct and complete To check and log compliance to the newly installed train control technology.
Konkret heisst dies in der Regel, dass alle Signalbegriffe eines Signals einzustellen sind und die Richtigkeit der Ausgabe an der ETCS Balise mittels Telegrammempfang und Verifikation des gesendeten Inhalts zu prüfen ist.Specifically, this usually means that all the signal terms of a signal must be set and the correctness of the output on the ETCS Balise must be checked by means of telegram reception and verification of the transmitted content.
Die Aufgabe der Prüfung ist bei Relaisstellwerken besonders schwierig, da diese als Zustandsautomaten ausgebildet sind und dadurch über keine Datenschnittstellen verfügen, über welche mittels Diagnoserechner einzelne funktionale Elemente ausserhalb des Fahrstrassen-Stellprozesses beeinflusst werden können.The task of the test is particularly difficult at relay interlockings, since these are designed as state machines and thus have no data interfaces, via which individual functional elements outside the driving-path setting process can be influenced by means of a diagnostic computer.
Eine der generellen Schwierigkeiten besteht darin, dass mittels der Einstellung von Fahrstrassen teilweise nur mit grossem Aufwand oder gar nicht eine Einstellung von bestimmten Fahrbegriffen an einem spezifischen Signal möglich ist. Diese Situation besteht unter anderem bei der Rückfallebene der Signalisierung im Störungsfall, hier ist das Herbeiführen der jeweiligen Störungen erforderlich um die Auswirkungen anzustossen.One of the general difficulties is that by means of the setting of routes it is sometimes possible only with great effort or not at all a setting of certain driving terms on a specific signal. This situation exists, among other things, in the fallback of the signaling in the event of a malfunction, here the induction of the respective disturbances is required to initiate the effects.
Weiter kommt hinzu, dass das gesamte zu prüfende Spektrum der Signaltypen die Hauptsignale, Vorsignale, Block- und Deckungssignale beinhaltet. Nachfolgend wird jedoch exemplarisch nur vom Signal gesprochen, bevorzugt ein Hauptsignal.In addition, the entire spectrum of signal types to be tested includes the main signals, pre-signals, block and coverage signals. In the following, however, only the signal is spoken by way of example, preferably a main signal.
Um diese Fahrbegriffe prüfen zu können, müssen somit verschiedene Fahrwege eingestellt werden (zum Teil quer über die gesamte Gleisanlage eines Bahnhofs), was mit der heutigen Dichte des Zugverkehrs meist nicht mehr vertretbar durchführbar ist.In order to be able to check these driving terms, different routes must therefore be set (sometimes across the entire track system of a station), which is usually no longer feasible feasible with the current density of train traffic.
Die bisherige exemplarische Lösung wird anhand von Spurplan-Relaisstellwerken, wie der Typ DOMINO 67 der Anmelderin, welcher verbreitet in der Schweiz im Einsatz steht, beschrieben.The previous exemplary solution is described on the basis of track-plan relay interlockings, such as the DOMINO 67 of the applicant, which is widely used in Switzerland in use.
Die Betreiber von Relaisstellwerken lassen in der Regel Eingriffe für eine Funktionsbeeinflussung nicht zu, verbieten sie jedoch auch nicht generell. In der Folge werden nach einem bekannten Vorgehen zur Durchführung von Prüfungen im Relaisstellwerk in einer Systemeinheit, das heisst dem einem Signal zugehörigen Relaissatz, alle in die Funktion involvierten Sicherheitsrelais von Hand in die erforderliche Lage gebracht und mechanisch mittels eines Keils in der Anzugslage arretiert. Mit der zwangsweise eingenommenen Stellung der dem zu prüfenden Signals zugehörigen Sicherheitsrelais wird der gewünschte Signalbegriff erzwungen.The operators of relay interlockings usually do not allow intervention for a functional influence, but they do not generally prohibit. As a result, according to a known procedure for carrying out tests in the relay interlocking in a system unit, that is, the relay set associated with a signal, all safety relays involved in the function are brought by hand to the required position and locked mechanically by means of a wedge in the attracting position. With the forcibly assumed position of the signal to be tested associated safety relay of the desired signal concept is enforced.
Verkeilungen sind mechanische Eingriffe an Sicherheitsrelais und dadurch kann unbeabsichtigt und unerkannt eine Beschädigung am Relais verursacht werden. Das kann gravierende sicherheitsrelevante Auswirkungen haben.Keystrokes are mechanical interventions on safety relays, which can cause damage to the relay unintentionally and unrecognized. This can have serious security implications.
Ein zweites Vorgehen besteht im Stellen des höchsten Fahrbegriffs und in der Folge werden mittels Wegdrücken oder Abdrücken von angezogenen Relais alle tieferwertigen Fahrbegriffe gebildet.A second approach is to set the highest driving concept and, as a result, all lower-level driving concepts are formed by pushing away or by pressing on energized relays.
Verkeilen und Abdücken sind Vorgehen ohne einheitliche technische Basis und bergen deshalb Gefahren. Solche Vorgehensweisen erfordern hohes Fachwissen sowie eine genaue Anleitung und eine strenge Protokollierung. Es besteht jedoch infolge der an sich unübersichtlichen Vorgehensweise die Schwierigkeit, die Regressionsfähigkeit der Tests zu gewährleisten.Wedging and pulling down are procedures without a uniform technical basis and therefore harbor dangers. Such procedures require a high level of expertise as well as accurate guidance and strict logging. However, due to the intricate nature of the procedure, there is the difficulty of ensuring the regression capability of the tests.
Generell ist festzuhalten, durch die manuellen Eingriffe im Relaissatz können folgende Gefahren oder Behinderungen entstehen:
- Manipulation am "falschen" Relais. Dieser Erstfehler kann mit einem zweiten unabhängigen Fehler zu einer Gefährdung führen (Mehrfehlerfall)
- Mechanische Beschädigung durch das Verkeilen oder Abdrücken der Relais
- Nach dem Beenden der Prüfung verkeiltes Relais nicht befreien
- Bei Ausfahrsignal wird Block angeschaltet, was zu betriebshemmenden Zuständen kann und indirekt Risiken bewirken kann.
- Manipulation on the "wrong" relay. This first error can lead to a danger with a second independent error (multi-error case)
- Mechanical damage due to wedging or forcing the relays
- After completing the test, do not release the wedged relay
- When the exit signal block is turned on, which can to operating conditions and can cause indirect risks.
Es wird ein Verfahren und eine Vorrichtung vorgeschlagen, welches keine Eingriffe an den Sicherheitsrelais der Systemeinheiten, der Relaissätze erfordert.A method and an apparatus is proposed which does not require any interventions on the safety relays of the system units of the relay sets.
Es sind zwei Funktionsbereiche im Spurplan-Relaisstellwerk von Bedeutung, welche auf eine neue Lösung für die Tests entscheidenden Einfluss haben.
- 1. Der Zentralverschluss mit seiner Relaissatzüberwachung, welcher das gesamte Stellwerk sicherheitstechnisch kontrolliert (sozusagen die Achillesferse der Sicherheit).
- 2. Die Spurplantechnik mit der Fähigkeit, dass die spezifischen Relais(steuer)sätze der Aussenanlageelemente diejenigen Eigenschaften besitzen, welche sie befähigen, bei der Fahrstrasseneinstellung die Gleisbelegung (Stellen und Auflösung) zu verwalten. Die Relais(steuer)sätze sind selbst Zustandsautomaten und somit deterministisch.
- 1. The central lock with its relay set monitoring, which controls the entire interlocking safety-related (so to speak, the Achilles heel of safety).
- 2. The track planning technique with the ability that the specific relay (control) sets of outdoor equipment elements have the characteristics that enable them to manage the track occupancy (locations and resolution) in the course setting. The relay (control) sets are themselves state machines and thus deterministic.
Es wird in der Grundsatzfunktion einheitlicher jedoch ein auf den Signaltyp optimierter Prüfsatz verwendet anstelle des Signal-Relaissatzes.
Dieser Prüfsatz verfügt über die Eigenschaften zum Ansteuern der Signale in der Aussenanlage.
Er verfügt jedoch nicht über Funktionen zum Einstellen einer Fahrstrasse, aber zum Einstellen des in Prüfung stehenden Hauptsignals (Ziel). Dadurch ist das Vordringen eines Zuges in den Bereich des jeweils zu prüfenden Signals aus signaltechnischer- wie auch aus der Forderung nach Prüfer-Personenschutz - nicht möglich. Gefahren durch einen herannahenden Zuges bestehen somit nicht mehr.In the basic function, however, a check set optimized for the signal type is used in a more uniform manner instead of the signal relay set.
This test set has the properties for controlling the signals in the outdoor system.
However, it does not have functions for setting a route, but for setting the main signal under test (destination). As a result, the advance of a train in the range of the respective signal to be tested from signaltechnischer- as well as from the demand for Prüfer-personal protection - not possible. Dangers from an approaching train no longer exist.
Die zu prüfenden Fahrbegriffe werden mittels des Prüfsatzes simuliert.Die Eingabe im Prüfsatz kann manuell erfolgen oder es ist ein Interface zu einem Prüfrechner möglich, über welchen die Prüfprozedur systematisiert werden kann.
Der Prüfsatz beschaltet jedoch die Ringleitung des Zentralverschlusses im Stellwerk, so dass die Funktion des Stellwerkes gesamthaft nicht beeinträchtigt ist.The driving terms to be tested are simulated by means of the test record. The input in the test record can be carried out manually or an interface to a test computer is possible via which the test procedure can be systemized.
However, the test set connects the loop of the central lock in the interlocking, so that the function of the interlocking is not impaired overall.
Eine Fahrstrasse mit einem Ziel-Prüfling kann daher erst wieder eingestellt werden, wenn der Prüfsatz gegen den entsprechenden Relaissatz des Signals wieder zurück getauscht worden ist.A route with a destination test object can therefore only be set again when the test set has been exchanged for the corresponding relay set of the signal.
Das Vorgehen in Einzelschritten bei der Prüfung eines Signals mit deren zusätzlich installierten ETCS-Zugsicherungseinrichtungen ist vorzugsweise dargestellt.The procedure in individual steps when testing a signal with its additionally installed ETCS train protection devices is preferably shown.
Zugslagen in der Gleisanlage mit Fahrdienst feststellen und Prozedur Startzeitpunkt festlegen
- 1. (Relais)-Prüfsatz entsprechend der Aufgabe einstellen (Grundstellung)
- 2. Betreffenden Relaissatz des betreffenden Signals entfernen
- 3. Prüfsatz einsetzen
- 4. Gemäss Prüfprotokoll den erstmöglichen Fahrbegriff am Prüfsatz simulieren
- 5. Prüfung der Übereinstimmung in der Aussenanlage bezüglich Telegramminhalt
- 6. Die weiteren Fahrbegriffe der Signalfunktion des Standortes gemäss Punkt 3 und 4 prüfen
- 7. Nach Beenden der Prüfung den Prüfsatz gegen entsprechenden Relaissatz zurücktauschen
- 8. Prüfen, ob HALT-Rückmelder aktiv ist, das heisst, der Satz ist in Grundstellung
- 9. Signalfreigabe an Fahrdienstleiter für die Nutzung im Betriebsablauf
- 1. Set (relay) test set according to the task (basic position)
- 2. Remove the relevant relay set of the relevant signal
- 3. Insert test set
- 4. According to the test report, simulate the first possible driving concept on the test set
- 5. Checking the conformity in the outdoor installation regarding telegram content
- 6. Check the further driving terms of the signal function of the location according to points 3 and 4
- 7. After completing the test, swap the test set for the corresponding relay set
- 8. Check if HALT-feedback is active, ie the set is in basic position
- 9. Signal release to dispatcher for use in operation
Der erfinderische Schritt liegt darin, dass ein neues Verfahren und eine Einrichtung festgelegt wird, welche die Nachteile der Verkeilmethode bezüglich Personensicherheit sowie Regression und insbesondere Fehleranfälligkeit durch manuelle handwerklich anspruchsvolle Handhabungen eliminiert.The inventive step is that a new method and a device is set, which eliminates the disadvantages of the wedging method in terms of personal safety and regression, and in particular error-prone by manual manual handling sophisticated.
