Abstract

The invention relates to a method for controlling the sequence of trains during traffic control, whereby a telephone communication between a traffic controller in a traffic control centre and a driver is carried out. In order to increase security during telephone communication, the traffic controller transmits a driving permit to the driver, in addition to a test code which is specific to the driving permit and determined by a traffic control computer, and the driver inputs the driving permit and the test code into a vehicle appliance which calculates the test code according to the same algorithm as the traffic control computer, and compares the calculated test code with the inputted test code. The driving permit is authenticated only if the two codes correspond.

Description

Beschreibungdescription
Verfahren zur Sicherung der Zugfolge im ZugleitbetriebProcedure for securing the train sequence in train control mode
Die Erfindung betrifft ein Verfahren zur Sicherung der Zugfolge im Zugleitbetrieb gemäß dem Oberbegriff des Anspruchs 1 sowie eine diesbezügliche Vorrichtung gemäß dem Oberbegriff des Anspruchs 3.The invention relates to a method for securing the train sequence in train control operation according to the preamble of claim 1 and a related device according to the preamble of claim 3.
Auf Strecken mit geringem Verkehr wird die Sicherung der Zugfolge häufig im Zugleitbetrieb realisiert. Dabei regelt der Zugleiter Zug- und Rangierfahrten auf einer zugeordneten Zugleitstrecke mit Zuglaufmeidungen und anderen Meldungen. Der Zugleiter führt ein Zugmeldebuch, in das der Betriebszustand der Zugleitstrecke, d. h. die an die Triebfahrzeugführer fernmündlich übermittelten Fahrerlaubnisse zum Befahren der Zugleitstrecke eingetragen werden. Aufgrund fehlender technischer Sicherung sind im Zugleitbetrieb nur geringe Geschwindigkeiten, insbesondere bis 60 km pro Stunde und bei Erfül- lung bestimmter Voraussetzungen bis 80 km pro Stunde zugelassen. Die Zuglauf erfolgung findet im Zugleitbetrieb nur in Form des handschriftlich geführten Zugmeldebuchs statt. Es stehen keine rechnergestützten Zuglaufdaten zur Anbindung an andere Informations- und Dispositionssysteme zur Verfügung.On routes with little traffic, the securing of the train sequence is often implemented in the train control mode. The train manager regulates train and shunting runs on an assigned train route with train avoidance and other messages. The train manager keeps a train log, in which the operating status of the train route, i.e. H. the driver's licenses for driving on the train route that are sent to the driver by telephone are entered. Due to the lack of technical security, only low speeds are permitted in the train control mode, in particular up to 60 km per hour and if certain conditions are met up to 80 km per hour. The train running takes place in the train control mode only in the form of the handwritten train log. There is no computer-aided train routing data available for connection to other information and disposition systems.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen und ein Verfahren der gattungsgemäßen Art anzugeben, das mit geringem technischen Aufwand eine sicherheitliche Ergänzung des Zugleitbetriebes ermöglicht .The invention has for its object to eliminate these disadvantages and to provide a method of the generic type that enables a safe addition to the train control operation with little technical effort.
Die Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch die Einführung des fahrerlaubnisspezifischen Prüfcodes ist die Übermittlung einer Fahrerlaubnis, für die die sicherheitlichen Voraussetzungen nicht erfüllt sind, technisch ausgeschlossen. Außerdem wird die Einhaltung der Fahrerlaubnis auf dem Triebfahrzeug technisch überwacht. Der Prüfcode garantiert eine technische Absicherung der fern- mündlichen Kommunikation, wobei abgesichert ist, dass der Zugleiter keine Fahrerlaubnis erteilen kann, die er nicht vorher durch Eingabe in den Zugleitrechner auf Zuverlässigkeit geprüft hat und auch dass der Triebfahrzeugführer keine Bestätigung für eine Fahrerlaubnis erhält, wenn er in das Fahrzeuggerät eine Fahrerlaubnis eingibt, die er vorher nicht bzw. nicht in dieser Form erhalten hat. Der Prüfcode wird durch einen manuell nicht nachvollziehbaren Algorithmus aus den Daten der aktuellen Betriebssituation berechnet. Dabei ist natürlich sicherzustellen, dass sich die Prüfcodes nicht mit nachvollziehbarer Regelmäßigkeit wiederholen können.The object is achieved with the characterizing features of claim 1. Through the introduction of the driver's license-specific test code, the transmission of a driver’s license, for which the security requirements are not met, technically excluded. In addition, compliance with the driving license on the locomotive is technically monitored. The test code guarantees a technical security of the telephonic communication, whereby it is ensured that the train manager cannot issue a driving license that he has not previously checked for reliability by entering it in the train control computer and that the driver does not receive a confirmation of a driving license if he enters a driver's license into the vehicle device that he has not previously received or has not received in this form. The check code is calculated by a manually incomprehensible algorithm from the data of the current operating situation. Of course, it must be ensured that the check codes cannot be repeated with comprehensible regularity.
Durch den damit verbundenen Sicherheitsgewinn sind Geschwindigkeiten bis 100 km/h genehmigungsfähig.The associated safety gain means that speeds of up to 100 km / h can be approved.
Der Zugleiter verfügt in der Zugleitzentrale über einen Zug- leitrechner, in den - anstelle oder zusätzlich zum Zugmeldebuch - alle Zuglaufmeldüngen eingegeben werden und indem somit ständig eine Datenbasis zur aktuellen Betriebslage auf der Zugleitstrecke vorliegt. Jede Fahrerlaubnis ist vor der fernmündlichen Übermittlung an den Triebfahrzeugführer in den Zugleitrechner einzugeben. Die Eingabe kann auf effektivste Weise ähnlich wie bei Fahrstraßen durch Start-Ziel-Bedienung erfolgen. Der Zugleitrechner nimmt eine Zulässigkeitsprüfung vor und weist bei einem sicherheitskritischen Konflikt die Fahrerlaubnis zurück. Für eine abgewiesene Fahrerlaubnis wird durch den Zugleitrechner kein Prüfcode ermittelt.The train manager has a train control computer in the train control center, in which - instead of or in addition to the train logbook - all train routing notifications are entered and thus there is always a database of the current operating situation on the train control route. Each driver's license must be entered in the train control computer before being transmitted to the driver by telephone. The entry can be made in the most effective way, similar to routes, by start-finish operation. The train control computer carries out an admissibility check and rejects the driver's license in the event of a safety-critical conflict. The train control computer does not determine a test code for a rejected driver's license.
An Bord des Triebfahrzeuges befindet sich ein einfaches Fahrzeuggerät. Die vom Zugleiter fernmündlich an den Triebfahr- zeugführer übermittelte Fahrerlaubnis wird zusammen mit demThere is a simple vehicle device on board the locomotive. The telephone from the train conductor to the Driver's license transmitted together with the
Prüfcode vom Triebfahrzeugführer in das Fahrzeuggerät eingegeben. Das Fahrzeuggerät überprüft die Richtigkeit der eingegebenen Fahrerlaubnis und vergleicht das Fahrziel mit dem ak- tuellen Zugstandort. Steht der Fahrerlaubnis nichts entgegen, wird diese auf dem Display des Fahrzeuggerätes als gültige Fahrerlaubnis angezeigt, andernfalls wird sie vom Fahrzeuggerät zurückgewiesen. Beim Erreichen der Fahrerlaubnisgrenze, d. h. des Fahrzieles, für das die Fahrerlaubnis erteilt wur- de, wird der Triebfahrzeugführer durch eine Anzeige und gegebenenfalls ein akustisches Signal auf das Einholen einer neuen Fahrerlaubnis hingewiesen. Wird die Fahrerlaubnisgrenze überfahren, ertönt ein Warnsignal, das den Triebfahrzeugführer zum sofortigen Halten auffordert .The driver entered the test code in the vehicle device. The vehicle device checks the correctness of the entered driver's license and compares the destination with the current train location. If there is nothing to prevent the driver's license, it will appear on the display of the vehicle device as a valid driver's license, otherwise it will be rejected by the vehicle device. When the driving license limit is reached, i.e. H. At the destination for which the driver's license has been granted, the driver is informed of the need to obtain a new driver's license by a display and, if necessary, an acoustic signal. If the driving license limit is exceeded, a warning signal sounds, which prompts the driver to stop immediately.
Bei der Eingabe der von dem Zugleiter fernmündlich übermittelten Fahrerlaubnis in das Fahrzeuggerät durch den Triebfahrzeugführer ist der ebenfalls übermittelte Prüfcode mit einzugeben. Das Fahrzeuggerät berechnet nach dem gleichen Al- gorithmus wie der Zugleitrechner für jede eingegebene Fahrerlaubnis den Prüfcode und vergleicht diesen mit dem vom Triebfahrzeugführer eingegebenen Prüfcode. Bei Nichtübereinstimmung des manuell eingegebenen mit dem berechneten Prüfcode wird die Fahrerlaubnis zurückgewiesen. Da der Triebfahrzeug- führer den Prüfcode selbst nicht bestimmen kann und somit zur Eingabe einer gültigen Fahrerlaubnis auf die Übermittlung des Prüfcodes durch den Zugleiter angewiesen ist, ist es nicht möglich, für eine irrtümlich eingegebene Fahrerlaubnis, für die nicht zuvor in der Zugleitzentrale die Zulässigkeit über- prüft wurde und somit ein Prüfcode vorhanden ist, eine Bestätigung dieser Fahrerlaubnis, d. h. eine gültige Fahrerlaubnis, zu erhalten. Gemäß Anspruch 2 ist ein ähnliches Sicherungsverfahren auch bei der Übermittlung einer Zuglaufmeldung von dem Triebfahrzeugführer an den Zugleiter vorgesehen. Vor Abgabe der Zuglaufmeldung, die zur sicherheitlichen Freigabe von vorauslie- genden Gleisabschnitten vorgesehen ist, wird diese Meldung zunächst von den Triebfahrzeugführer in das Fahrzeuggerät eingegeben, welches den zugehörigen Prüfcode berechnet. Anschließend übermittelt der Triebfahrzeugführer die Zuglaufmeldung samt Prüfcode an den Zugleiter, der beide Datensätze in den Zugleitrechner eingibt. Der Zugleitrechner berechnet nach dem gleichen Algorithmus wie das Fahrzeuggerät für jede eingegebne Zuglaufmeldung den Prüfcode und vergleicht diesen mit dem manuell eingegebenen Prüfcode. Bei Nichtübereinstimmung des eingegebenen mit dem berechneten Prüfcode wird die Zuglaufmeidung zurückgewiesen. Dadurch, dass der Zugleiter den Prüfcode nicht selbst bestimmen kann und somit zur Eingabe einer gültigen Zuglaufmeldung auf die Übermittlung des Prüfcodes durch den Triebfahrzeugführer angewiesen ist, besteht keine Möglichkeit, einen zugehörigen Gleisabschnitt irrtümlicherweise freizugeben.When the driver is given the driver's license transmitted by telephone by the train manager to the vehicle device, the test code, which is also transmitted, must also be entered. The vehicle device calculates the test code for each driver's license entered using the same algorithm as the train control computer and compares it with the test code entered by the driver. If the manually entered and the calculated test code do not match, the driver's license is rejected. Since the driver cannot determine the test code himself and is therefore dependent on the transmission of the test code by the train manager in order to enter a valid driver's license, it is not possible for an incorrectly entered driver's license for which the admissibility has not previously been entered in the train control center - has been checked and thus a check code is available to receive a confirmation of this driver's license, ie a valid driver's license. According to claim 2, a similar security procedure is also provided for the transmission of a train running message from the driver to the train manager. Before submitting the train running message, which is provided for the safe release of the preceding track sections, this message is first entered by the driver into the vehicle device, which calculates the associated test code. The driver then transmits the train running message together with the test code to the train manager, who enters both data records in the train control computer. The train control computer uses the same algorithm as the vehicle device to calculate the test code for each train report message entered and compares it with the manually entered test code. If the entered test code does not match, the train run avoidance is rejected. Because the train manager cannot determine the test code himself and is therefore dependent on the transmission of the test code by the driver in order to enter a valid train running message, there is no possibility of mistakenly releasing an associated track section.
Die Übermittlung einer Zuglaufmeidung von einem örtlichen Bahnhofsfahrdienstleiter an den Zugleiter wäre bei Bedarf in ähnlicher Weise zu realisieren.The transmission of a train routing avoidance from a local station dispatcher to the train manager would be implemented in a similar manner if necessary.
Gemäß Anspruch 3 sind bei einer Vorrichtung zur Durchführung des Verfahrens im Wesentlichen folgende Komponenten erforderlich: ein Zugleitrechner in der Zugleitzentrale für die Zuläs- sigkeitsprüfung und die Berechnung des Prüfcodes eine Kommunikationseinrichtung zwischen Zugleitzentrale und Triebfahrzeug sowie ein Fahrzeuggerät zur Berechung des fahrerlaubnisspezifischen Prüfcodes und mit einer Vergleichseinrichtung zum Vergleich des manuell eingegebenen mit dem berechneten Prüfcode. Für Strecken mit schwachem Verkehr sind somit nur relativ wenig neue Infrastrukturkomponenten erforderlich. Die Kommunikation erfolgt dabei über die vorhandene Kommunikationstechnik. Ein Sicherheitsgewinn ergibt sich auch, wenn nicht alle Triebfahrzeuge mit dem Fahrzeuggerät ausgestattet sind. Zwar können sich gewisse betriebliche Einschränkungen, insbesondere hinsichtlich Geschwindigkeitsbeschränkungen, ergeben, jedoch sind keine aufwendigen technischen Zusatzeinrichtungen in der Zugleitzentrale erforderlich.According to claim 3, the following components are essentially required in an apparatus for carrying out the method: a train control computer in the train control center for the admissibility check and the calculation of the test code, a communication device between the train control center and the locomotive and a vehicle device for calculating the driver's license-specific test code and with a comparison device for comparing the manually entered with the calculated test code. This means that relatively few new infrastructure components are required for routes with light traffic. Communication takes place via the existing communication technology. There is also an increase in safety if not all traction vehicles are equipped with the vehicle device. Certain operational restrictions may arise, particularly with regard to speed restrictions, but no complex additional technical equipment is required in the train control center.
Der Zugleitrechner ist gemäß Anspruch 4 vorzugsweise als signaltechnisch sicherer Rechner mit History-Funktionen ausgebildet. Nur diese signaltechnisch sichere Lösung ermöglicht, auf die Führung des handschriftlichen Zugmeldebuches für den Zugleitbetrieb zu verzichten. Um bei Ausfall des Zugleitrech- ners dem Betrieb mit einem handschriftlichen Zugmeldebuch weiterführen zu können, muss der Zugleitrechner über eine gesicherte History-Funktion verfügen, aus der die unmittelbar vor dem Ausfall bestehende Betriebslage mit allen Zugstandorten und erteilten Fahrerlaubnissen abgerufen und ins Zugmel- debuch übertragen werden kann.The train control computer is preferably designed as a signal-safe computer with history functions. Only this solution, which is secure in terms of signaling technology, makes it possible to dispense with the maintenance of the handwritten train logbook for train control operations. In order to be able to continue operation with a handwritten train logbook in the event of a train control computer failure, the train control computer must have a secured history function from which the operating situation with all train locations and issued driving licenses immediately prior to the failure can be called up and transferred to the train log book can be.
Die Wahl einer signaltechnisch sicheren Lösung würde auch die Integration des Zugleitrechners in die Bedienoberfläche von elektronischen Stellwerken erlauben. Damit wäre es möglich, aus einer Bedienoberfläche sowohl stellwerksgesteuerte Strecken als auch Zugleitstrecken zu steuern. Die Datenbasis des Zugleitrechners erlaubt auch die Anbindung an Dispositions- systeme, also dass auch in den Betriebsleitstellen regionale Netze in die Disposition von stellwerkgesteuerten Strecken und Zugleitstrecken in ein System integriert werden können.The choice of a signal-safe solution would also allow the integration of the train control computer in the user interface of electronic signal boxes. This would make it possible to control both interlocking-controlled routes and train control routes from one user interface. The data base of the train control computer also allows the connection to disposition systems, that is, also in the operations control centers regional Networks in the disposition of interlocking-controlled routes and train routes can be integrated into one system.
Das Fahrzeuggerät ist gemäß einer in Anspruch .5 gekennzeich- neten bevorzugten Ausführungsform als signaltechnisch nicht sicherer Rechner mit History-Funktion ausgebildet. Der Fahrzeugrechner erteilt dem Triebfahrzeugführer keine unmittelbare Freigabe zur Fahrt, sondern greift beim Offenbaren von Fehlern nur hemmend in den Betrieb ein. Ein Versagen des Fahrzeuggerätes kann allein nicht zu einer Gefährdung führen. Dazu muss immer ein Fehlverhalten des Triebfahrzeugführers vorliegen. Folglich ist eine signaltechnisch nicht sichere und damit technisch weniger aufwendige Lösung ausreichend. Dennoch sollten alle Anzeigen und Eingaben des Fahrzeuggerä- tes für nachträgliche Auswertungen bei Unregelmäßigkeiten mittels History-Funktionen protokollierbar sein.According to a preferred embodiment characterized in claim .5, the vehicle device is designed as a signal-insecure computer with a history function. The vehicle computer does not give the driver direct approval for the journey, but only interferes with the operation when errors are revealed. Failure of the vehicle device alone cannot lead to a hazard. To do this, the driver must always have misconduct. As a result, a solution that is not secure in terms of signal technology and is therefore less technically complex is sufficient. Nevertheless, all displays and inputs of the vehicle device should be logable for subsequent evaluations in the event of irregularities using history functions.
Falls örtliche Bahnhofsfahrdienstleiter mit Rechnern zur Berechnung der Prüfcodes ausgestattet werden, gelten ähnliche Anforderungen wie für die Fahrzeuggeräte. Auf eine gesicherteIf local station dispatchers are equipped with computers for calculating the test codes, similar requirements apply as for the vehicle devices. On a secured
History-Funktion kann jedoch bei diesen Rechnern gegebenenfalls verzichtet werden.However, history function can be omitted on these computers if necessary.
Nachfolgend wird die Erfindung anhand figürlicher Darstellun- gen näher erläutert. Es zeigen:The invention is explained in more detail below with the aid of figurative representations. Show it:

From Figure 1 is the procedure for issuing a
Fahrerlaubnis durch eine Zentrale an ein Fahrzeug ersichtlich. Nachdem einem Zugleiter in der Zentrale eine von einem Fahrzeugfuhrer fernmündlich übermittelte Fahranfrage vor- liegt, wird durch den Zugleiter eine entsprechende Fahrerlaubnis in einen Zugrechner eingegeben. Dieser prüft anhand des Belegungszustandes des angefragten Gleisabschnittes die Zulässigkeit der Fahrerlaubnis und berechnet einen fahrerlaubnisspezifischen Prüfcode. Die Fahrerlaubnis wird hernach in einer History-Datei des Zugleitrechners abgespeichert und auf einer Bildschirmanzeige des Zugleitrechners zusammen mit dem Prüfcode quasi erteilt. Diese Fahrerlaubnis wird durch den Zugleiter zusammen mit dem Prüfcode fernmündlich an den Fahrzeugfuhrer übermittelt . Der Fahrzeugfuhrer gibt die Fahr- erlaubnis und den Prüfcode in ein Fahrzeuggerät ein, welches eine Plausibilitätsprüfung, insbesondere hinsichtlich der aktuellen Fahrzeugposition und des Fahrtzieles, durchführt und den Prüfcode analog zum Zugleitrechner fahrerlaubnisspezifisch ermittelt. Danach wird die Fahrerlaubnis in einer History-Datei des Fahrzeuggerätes abgespeichert und als gültige Fahrerlaubnis angezeigt.Driver's license can be seen from a control center on a vehicle. After a train manager at the head office receives a driving request transmitted by telephone from a vehicle driver, the train manager enters a corresponding driver's license into a train computer. This checks the admissibility of the driver's license on the basis of the occupancy status of the requested track section and calculates a test code specific to the driver's license. The driver's license is then saved in a history file of the train control computer and quasi issued on a screen display of the train control computer together with the test code. This driver's license is transmitted by telephone to the vehicle driver together with the test code. The vehicle driver enters the driving license and the test code into a vehicle device, which carries out a plausibility check, in particular with regard to the current vehicle position and the destination, and determines the test code in a manner specific to the driver's license, analogous to the train control computer. The driver's license is then stored in a history file of the vehicle device and displayed as a valid driver's license.
In die Berechnung des Prüfcodes können insbesondere Angaben bezüglich Datum, Zugnummer und Ziel der Fahrerlaubnis ein- fließen.In particular, information regarding the date, train number and destination of the driver's license can be included in the calculation of the test code.
Auf diese Weise wird ein Sicherheitsniveau erreicht, das mit der Zugfolgesicherung auf Strecken mit nicht selbsttätigem Streckenblock ohne Zugbeeinflussung vergleichbar ist. Es ist auch eine stufenweise Umsetzung möglich, indem die Sicherung der Übermittlung von Meldungen auf das Erteilen der Fahrerlaubnis gemäß Figur 1 beschränkt wird. Damit wird durch Ver- hinderung der unzulässigen Abfahrt ohne Fahrerlaubnis bereits die größte Sicherheitslücke des Zugleitbetriebes geschlossen.In this way, a level of safety is achieved that is comparable to the protection of the train sequence on routes with a non-automatic route block without influencing the train. A step-by-step implementation is also possible in that the securing of the transmission of messages is restricted to the issue of the driving license according to FIG. 1. This means that preventing the inadmissible departure without a driver's license has already closed the greatest security gap in train control operations.

Fahrzeug eine von gegebenenfalls mehreren Zuglaufmeldstellen innerhalb einer Zugleitstrecke, für die die Zentrale zuständig ist, erreicht, wird zunächst die Zugvollständigkeit geprüft und in den Fahrzeugrechner eingegeben. Dieser berechnet den Prüfcode, der auch in der History-Datei abgespeichert wird. Der Prüfcode wird angezeigt und zusammen mit der Zuglaufmeldung fernmündlich an den Zugleiter in der Zentrale ü- bermittelt . Zuglaufmeldung und Prüfcode werden in den Zugleitrechner eingegeben, der eine Plausibilitätsprüfung durch- führt und ebenfalls den Prüfcode berechnet und diesen mit dem manuell eingegebenen Prüfcode vergleicht. Daraufhin werden die freizugebenden Gleisabschnitte festgelegt und in die History-Datei eingetragen. Die Bildschirmanzeige bestätigt die Korrektheit der Zuglaufmeldung oder signalisiert gegebe- nenfalls einen Fehlerzustand.If a train reaches one of several train routing reporting points within a train route for which the control center is responsible, the completeness of the train is first checked and entered into the vehicle computer. This calculates the test code, which is also saved in the history file. The test code is displayed and transmitted to the train manager at the control center by telephone together with the train running message. The train running message and the test code are entered into the train control computer, which carries out a plausibility check and also calculates the test code and compares it with the manually entered test code. The track sections to be released are then defined and entered in the history file. The screen display confirms the correctness of the train running message or signals an error status if necessary.
In die Berechnung des Prüfcodes für die Zuglaufmeldung können insbesondere das Datum, die Zugnummer, die Art der Zuglauf- meidung und die aktuelle Zuglaufmeldestelle einbezogen wer- den.In particular, the date, the train number, the type of train avoidance and the current train reporting office can be included in the calculation of the test code for the train running message.
Die Erfindung beschränkt sich nicht auf die vorstehend angegebenen Ausführungsbeispiele. Vielmehr ist eine Anzahl von Varianten denkbar, welche auch bei grundsätzlich anders gear- teter Ausführung von den Merkmalen der Erfindung Gebrauch machen. The invention is not limited to the exemplary embodiments specified above. Rather, a number of variants are conceivable which make use of the features of the invention even when the design is fundamentally different.
