Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Absetzen von Störungsmeldungen von einer dezentralen Funktionseinheit in einem Sicherungssystem für schienengebundenen Verkehr.The present invention relates to a method and apparatus for issuing fault messages from a remote functional unit in a rail-based traffic safety system.
Dezentrale Funktionseinheiten in Eisenbahn-Sicherungsanlagen haben in gewissen funktionalen und schaltungstechnischen Ausprägungen keine direkten elektrischen Verbindungen zu den zentralen Bereichen der ihr zugehörigen Sicherungsanlage, wie z.B. zu Stellwerken, um Informationen zum Betriebszustand beim Auftreten einer Regelabweichung in der bestimmungsgemässen Funktionalität mittels einer Störungsmeldung abzusetzen.Decentralized functional units in railway safety systems do not have any direct electrical connections to the central areas of their associated safety system in certain functional and circuit-related manifestations, such as e.g. to interlockings to issue information about the operating state when a control deviation in the intended functionality by means of a fault message.
Es kommt hinzu, dass Versorgungsenergie in den dezentralen Bereichen infolge ihrer aufwendigen Bereitstellung durch die Erfüllung der Kenngrössen "Verfügbarkeit und Qualität" nur sehr eingeschränkt bereitgestellt werden kann.In addition, energy supply in the decentralized areas can only be provided to a very limited extent as a result of their costly provision by meeting the parameters "availability and quality".
Die Bahnbetreiber ihrerseits haben die Aufgabe, den Betrieb möglichst störungsfrei und damit genau nach Fahrplan abzuwickeln. Gelingt das nicht, so kommt es zur Verschiebung der fahrplanmässigen Betriebsordnung und zum Teil auch zur Verärgerung der Bahnbenutzer und in der Folge ist durch Rückerstattungen oder Preisabschlägen an die Kunden mit Einbussen im Ergebnis beim Betreiber zu rechnen.The railway operators, for their part, have the task of completing the operation as trouble-free as possible and thus according to the timetable. If this does not succeed, then there is a shift in the scheduled operating rules and in part also to the annoyance of rail users and as a result is expected by refunds or discounts to customers with losses in the result at the operator.
Es ist deshalb wichtig, dass funktionale Störungen und insbesondere solche durch Ausfälle von Funktionseinheiten in der Infrastruktur unverzüglich an eine zentrale Stelle gemeldet werden. Damit eingeschlossen sind auch die dezentralen Einheiten der Sicherungsanlagen.It is therefore important that functional disturbances, and in particular those due to failures of functional units in the infrastructure, be reported immediately to a central office. This also includes the decentralized units of the security systems.
Dadurch können ohne Verzögerung geeignete Massnahmen für die operative fahrdienstliche Ebene sowie für die Instandstellung der ausgefallenen Einheiten eingeleitet werden.As a result, suitable measures can be initiated without delay for the operative driver-service level and for the repair of the failed units.
Ein Teil der Funktionseinheiten kann mittels Datenaustausch von Zustandsparametern oder auch über eine quantitative Bewertung stromkreistypischer Parameter durch die Stellwerkanschaltung von der zentralen Seite her auf ihren Funktionsstatus bewertet werden. Die vollständige Abdeckung der Überprüfung ist dabei jedoch nicht gegeben.A part of the functional units can be evaluated for their functional status by means of data exchange of state parameters or also via a quantitative evaluation of circuit parameters typical by the interlocking connection from the central side. However, the full coverage of the review is not given.
Schwierig bis meist unmöglich ist es in der Regel, eine Störinformation an die zentrale Empfängerstelle durchzuleiten, wenn die betrachteten Funktionseinheiten sich am Ende einer Funktionskette befinden und nur Information bei anderen Einheiten lesen, nicht aber schreiben. Sie haben somit keinen Zugang zu den Verbindungen in die zentralen Bereiche für das Absetzen von Störungsmeldungen. Es bestehen damit für die Rückmeldung von Störungen in den zentralen Bereich erhebliche Lücken. Diese Lücken sind umso grösser, je mehr noch ältere Technologien in der betrachteten Anlage eingesetzt werden, was gerade im Bereich von Relaisstellwerken noch wesentlich ausgeprägter ist als im Umfeld moderner elektronischer Stellwerke.It is usually difficult, if not impossible, to pass on interference information to the central receiver site if the functional units considered are at the end of a functional chain and only read information from other units but not write. This means you will not have access to the links to the central trouble shooting sections. There are thus considerable gaps in the feedback of disruptions in the central area. These gaps are even greater the more older technologies are used in the system under consideration, which is even more pronounced in the area of relay interlockings than in the environment of modern electronic interlockings.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Absetzen von Störungsmeldungen von einer dezentralen Funktionseinheit in einem Sicherungssystem für schienengebundenen Verkehr anzugeben, bei denen Störungsmeldungen zuverlässig und mit Sicht auf den infrastrukturellen Aufwand einfach abgesetzt werden können. Die
Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 und 7 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind den davon abhängigen Patentansprüchen 2 bis 6 bzw. 8 bis 12 zu entnehmen.This object is solved by the features of claims 1 and 7. Advantageous embodiments of the invention can be found in the dependent claims 2 to 6 or 8 to 12.
Begleitend zu der immer stärkeren Präsenz von elektronischen Funktionseinheiten in den Schienennetzen der Bahnen ist somit die Frage nach der Energieversorgung und der Funktionsüberwachung solcher Einheiten gelöst. Die Anzahl der Einheiten nimmt Streckeneinheit resp. pro Streckenpunkt stetig zu, die Leistungsaufnahme geht tendenziell durch den Einsatz moderner Elektronik jedoch immer mehr zurück. Es werden daher vermehrt Speisesysteme verwendet, welche über einen Energiespeicher verfügen (z.B. Akku, über Supercap und andere), die aus einer oder mehr Quellen gespiesen werden. Sie arbeiten im Sub-Watt bis zum tieferen einstelligen Wattbereich.Accompanying the ever-increasing presence of electronic functional units in the railway railways, the question of the power supply and the functional monitoring of such units is thus solved. The number of units takes distance unit resp. per waypoint steadily increasing, but power consumption tends to decline more and more due to the use of modern electronics. There is therefore an increasing use of feed systems which have energy storage (e.g., battery, supercap, and others) fed from one or more sources. They work in sub-watt to the lower single-digit watt range.
Erfindungsgemäss ist es nun vorgesehen, die Speisung resp. die Speiseeinheit einer gestörten Funktionseinheit dahingehend zu nutzen, im dem die Speisung auf eine in der Automatisierungstechnik breit eingesetzte Mobileinheit (z.B. ein GSM Sendemodul) umgeschaltet wird und diese in der Folge eine Störungsmeldung für die gestörte Einheit absetzt. Dieses Verfahren kann single wie auch multiple angewendet werden, das heisst ein Sendemodul nimmt Fehlermeldungen/Zustandsmeldungen von nur einer oder von mehreren Funktionseinheiten entgegen und setzt sie ab.According to the invention, it is now provided, the supply resp. to use the supply unit of a faulty functional unit in that the supply to a widely used in automation technology mobile unit (for example, a GSM transmitter module) is switched and this sets in the sequence of a fault message for the faulty unit. This method can be used single as well as multiple, that is to say a transmission module accepts error messages / status messages from only one or more functional units and sets them down.
Bevorzugte Ausführungsbeispiele der vorliegenden Erfindung werden anhand einer Zeichnung näher erläutert. Dabei zeigt die Figur in schematischer Ansicht ein Signal 2, das neben einem Gleis 4 angeordnet ist. Das Signal 2 verfügt im Bereich des Gleises 4 über eine Stromversorgung 6. Diese Stromversorgung 6 ist ein Teil der Steuerungseinheit 8 für das Signal 2. Die Spannungsversorgung 6 kann aber auch eine durch mehrere Steuerungseinheiten genutzte Energiebasis, welche eine dezentrale autonome oder teilautonome Produktion von elektrischer Betriebsenergie ermöglicht. Die Steuerungseinheit weist zudem ein Steuermodul 10 auf, das das Signal 2 und dessen Signallampen ansteuert. Das Steuermodul 10 weist aber auch einen Speicher auf, in dem eine Störungsmeldung 16 für die Funktionen des Signals 2 und der Steuerungseinheit 8 konfiguriert ist. Die Störungsmeldung 16 wird vorliegend über ein in die Steuerungseinheit 8 integrierte GSM-Funkmodul 14 abgesetzt.Preferred embodiments of the present invention will be explained in more detail with reference to a drawing. The figure shows a schematic view of a signal 2, which is arranged next to a track 4. The power supply 6 is a part of the control unit 8 for the signal 2. The power supply 6 can also be used by a plurality of control units energy base, which is a decentralized autonomous or teilautonome production of electrical Operating power allows. The Control unit also has a
Die Steuerungseinheit 8 (eine oder mehrere möglich) im Gleisbereich am lokal gleichen Ort, welche auf Ausfall überwacht werden müssen und über keine eigene Fehleroffenbarung über Stellwerkkabel oder Speisekabel 18 verfügen, verwendet beispielsweise ein bistabiles Relais 12, welches über einen Umschaltkontakt für die Speisung und einen Arbeitskontakt für die Betriebszustandsinformation verfügt.The control unit 8 (one or more possible) in the track area at the same location locally, which must be monitored for failure and have no own error disclosure on interlock cable or
Beim Initialisieren der Bahnanlage wird das bistabile Relais 12 in die Speisestellung für das zugehörige Steuermodul 10 gesetzt. Es liegt daher weder eine Speisespannung noch die Betriebszustandsinformation (Störungsinformation) am GSM-Funkmodul 14.When initializing the railway system, the
Kommt es nun aber zu einer Störung in der Steuerungseinheit 8 und dem von ihr gesteuerten Signal 2, so schaltet diese Steuerungseinheit ihr bistabiles Relais 12 für die Speisung um, trennt sich hinsichtlich des Teils für die Betriebszustandsinformation von der Versorgung und meldet für seine Betriebszustandsinformation den Zustand "gestört an das GSM-Funkmodul, welches eine Information mit den Koordinaten und allenfalls weiterer Information zur Störung an eine zentrale Stelle, wie z.B. das Stellwerk, meldet.If, however, a fault occurs in the control unit 8 and the signal 2 which it controls, this control unit switches its
Die wesentlichen Schritte des Verfahrens sind daher wie folgt zusammenfassbar:
- 1. Initialisierung eines Sendemoduls (z.B. GSM-Funkmodul 14) durch die Speiseanschaltung (z.B. 6) über eines der bistabilen Speiseumschalt-
Relais 12 einer der am Streckenpunkt, z.B. dem Signal 2, betriebenen Funktionseinheit, z.B. Steuerungseinheit 8. - 2. Konfigurieren einer Störungsmeldung (z.B. in Form einer SMS, die eine Störinformation der Funktionseinheit umfasst).
- 3. Absenden der Störungsmeldung (SMS) vorzugsweise an die zentrale Störmeldestelle (wie z.B. ein zentrales Stellwerk) im Falle einer Störung.
- 4. Optional: periodische Wiederholung der Absetzung der Störmeldung
- 5. Optional: Empfangen einer Quittung (Empfangsbestätigung und damit Rücksetzen der SMS-Ausgabe.

bistable Speiseumschalt relay 12 one of the at the waypoint, eg the signal 2, operated functional unit, eg control unit. 8 - 2. Configure a fault message (eg in the form of an SMS, which includes fault information of the functional unit).
- 3. Sending the fault message (SMS) preferably to the central fault reporting point (such as a central interlocking) in the event of a fault.
- 4. Optional: periodic repetition of the cancellation of the fault message

- 6. Optional: Sending an alive telegram
- 7. Optional: Send RAM (S) messages
Ansatz für die angemessene Überprüfung der Funktion der ZustandsrückmeldungApproach to adequately check the function of the status feedback
Die Ausfallrate und damit die Zuverlässigkeit bei nicht bestromten (nicht im Betrieb stehenden) elektronischen Bauelementen sind signifikant kleiner als bei im Betrieb stehenden Elementen. Das gilt sinngemäss generell für Funktionseinheiten. Durch die Prüfung bei der Inbetriebnahme kann die bestimmungsgemässe Funktionalität festgestellt werden. Danach erhält die Sendeeinheit bei ordnungsgemässer Funktion der ihr zugeordneten Funktionseinheiten an einem Signalstandort keine Versorgungsenergie. Die Ausfallwahrscheinlichkeit ist somit sehr klein.The failure rate and thus the reliability of non-energized (not in operation) electronic components are significantly smaller than those in operation elements. This applies mutatis mutandis to functional units. By checking during commissioning, the intended functionality can be determined. Thereafter, the transmitting unit receives no supply energy at the proper function of its associated functional units at a signal location. The probability of default is thus very small.
Besteht eine Anforderung an die durchgängige Offenbarung von Störungen in Streckenpunkten so kann bedarfsweise mit einer entsprechenden Steuerung periodisch das Sendemodul selbst für die Ausgabe einer Alive-Meldung (SMS) angestossen werden. In der Folge können auch die Funktionseinheiten im jeweiligen Streckenpunkt zum Senden von Status-Meldungen über das (temporär aktivierte) Sendemodul veranlasst werden. Überhaupt kann das bistabile Element nach dem Absetzen einer Störungsmeldung wieder in den normalen Betriebszustand schalten, damit die von der Funktionseinheit 8 noch störungsfrei zur Verfügung stellbaren Funktionalitäten weiter ausgeführt werden können.If there is a requirement for the continuous disclosure of disturbances in waypoints, the transmit module may periodically be required with a corresponding control even for the output of an Alive message (SMS). As a result, the functional units in the respective route point can also be made to transmit status messages via the (temporarily activated) transmission module. In general, the bistable element after switching off a fault message again switch to the normal operating state, so that the function of the unit 8 can still be provided without interference available functionalities can be performed.
Der besondere Pfiff der vorliegenden Erfindung wird daher darin gesehen, dass durch das Umlegen der Speisequelle von der gestörten Funktionseinheit auf bespielsweise ein ansonsten stromloses GSM- Funkmodul das Absetzen einer Störungsmeldung ermöglicht wird. Das Funkmodul kann dabei selbst auch auf Ausfälle überwacht werden. Es ist auch möglich, von der Position einer autonomen Steuereinheit aus ein auf die Funktionalität des Streckenpunktes abgestimmtes Testprogramm auszulösen.The special feature of the present invention is therefore seen in the fact that by placing the power source of the malfunctioning functional unit on recordable, an otherwise currentless GSM radio module, the discontinuation of a fault message is made possible. The radio module can itself be monitored for failures. It is also possible to trigger from the position of an autonomous control unit a tuned to the functionality of the waypoint test program.
