Abstract

The method involves creating a shelf mark in a station, and is dispatched for the initial notification of a station by another station. The shelf mark is received and signed from another station, and then again sent back to a station and is stored there. The received shelf mark is examined and if no errors are recognized, the transmission of data begins.

Description

Die Erfindung betrifft ein Verfahren zur Übertragung von Daten von einer ersten Station in einem Eisenbahnfahrzeug zu einer zweiten Station.The invention relates to a method for transmitting data from a first station in a railway vehicle to a second station.

Die zweite Station befindet sich in der Regel an einem festen Ort, z. B. in einem Bahnhof oder in einem Stellwerk. Sie kann sich aber auch in einem anderen Eisenbahnfahrzeug befinden.The second station is usually located at a fixed location, eg. B. in a train station or in a signal box. It can also be located in another railway vehicle.

Zur Übertragung von Daten aus einem Eisenbahnfahrzeug und insbesondere zu einer stationären Einrichtung hin werden häufig öffentliche Kommunikationsnetze verwendet. Dadurch besteht die Möglichkeit, dass ein unberechtigter Personenkreis übertragene Daten erhalten kann. Das gleiche Problem ist gegeben, wenn das Eisenbahnfahrzeug zur Datenübermittlung mit der zweiten Station über Funk in Verbindung steht.Public communications networks are often used to transmit data from a railway vehicle and, in particular, to a stationary facility. This gives the possibility that an unauthorized group of persons may receive transmitted data. The same problem exists when the railway vehicle communicates with the second station over the radio for data transmission.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Übertragung von Daten von einer ersten Station in einem Eisenbahnfahrzeug zu einer zweiten Station hin anzugeben, das das Ablesen der Daten durch nicht berechtigte Personen unterbindet. Trotzdem soll auf die große Verfügbarkeit öffentlicher Kommunikationsnetze nicht verzichtet werden.The invention has for its object to provide a method for transmitting data from a first station in a railway vehicle to a second station, which prevents the reading of data by unauthorized persons. Nevertheless, the great availability of public communication networks should not be left out.

Die Aufgabe wird gemäß der Erfindung dadurch gelöst, dass in der ersten Station eine Signatur erstellt und zur Erstanmeldung der ersten Station bei der zweiten Station an diese versandt wird, dass die Signatur von der zweiten Station empfangen, signiert und dann wieder an die erste Station zurückgesandt und dort abgelegt wird und dass erst dann mit der Übertragung der Daten begonnen wird.The object is achieved according to the invention in that a signature is created in the first station and sent to the first station at the first station to the first, that received the signature of the second station, signed and then sent back to the first station and is stored there and that only then begins with the transfer of the data.

Mit dem Verfahren nach der Erfindung wird der Vorteil erzielt, dass die Vertraulichkeit der Datenübertragung gewährleistet ist. Nur wenn die bekannte Signatur der zweiten Station bei der ersten Station eintrifft, ist sichergestellt, dass die zweite Station der gewünschte Empfänger ist. Die Daten können also nicht zu einer unberechtigten Station gelangen.With the method according to the invention, the advantage is achieved that the confidentiality of the data transmission is ensured. Only if the known signature of the second station arrives at the first station, it is ensured that the second station is the desired receiver. The data can not reach an unauthorized station.

Beispielsweise werden die jeweils empfangenen Signaturen überprüft und nur, wenn keine Fehler zu erkennen sind, wird mit der Übertragung von Daten begonnen. Damit wird der zusätzliche Vorteil erzielt, dass die Integrität der Datenübermittlung stets gegeben ist. Es werden vorteilhaft keine fehlerhaften Daten übermittelt.For example, the respective received signatures are checked and only if no errors are to be detected is the transmission of data begun. This provides the additional advantage that the integrity of the data transmission is always given. Advantageously, no erroneous data is transmitted.

Beispielsweise sendet eine der Stationen an die andere Station mehrere Vorschläge für Verschlüsselungsalgorithmen, aus denen die andere Station einen der Vorschläge auswählt und das Ergebnis an die zuerst genannte Station zurücksendet. Zu versendende Signaturen werden dann mit dem ausgewählten Verschlüsselungsalgorithmus verschlüsselt. Damit wird der Vorteil erzielt, dass die Vertraulichkeit der übertragenen Daten noch weiter verbessert wird.For example, one of the stations sends to the other station several suggestions for encryption algorithms, from which the other station selects one of the suggestions and sends the result back to the former station. Signatures to be sent are then encrypted with the selected encryption algorithm. This provides the advantage of further improving the confidentiality of the transmitted data.

Beispielsweise sendet die empfangende Station zur Überprüfung des Übertragungsvorgangs die empfangenen Daten an die sendende Station zurück. Sollten andere Daten als die abgesandten Daten zurückkommen, wäre das sofort ein Hinweis auf einen Fehler in der Übertragung und die betreffenden Daten würden nicht berücksichtigt.For example, to check the transmission process, the receiving station sends the received data back to the transmitting station. If any data other than the data sent back, this would immediately indicate an error in the transmission and the data in question would not be considered.

Die erste Station weist zum Senden und Empfangen von Daten beispielsweise ein Fernübertragungsgateway auf. Ein solches Fernübertragungsgateway ermöglicht einen zuverlässigen Datenfluss zwischen der Station im Eisenbahnfahrzeug und den einzelnen Bauelementen des Fahrzeuges. Auch die zweite Station kann beispielsweise ein Fernübertragungsgateway zum Senden und Empfangen von Daten aufweisen.The first station has, for example, a remote transmission gateway for transmitting and receiving data. Such a remote transmission gateway enables a reliable data flow between the station in the railway vehicle and the individual components of the vehicle. The second station may also have, for example, a long-distance transmission gateway for transmitting and receiving data.

Beispielsweise steht das Fernübertragungsgateway mit einem Zugbus in Verbindung.For example, the long-distance transmission gateway communicates with a train bus.

Der Zugbus steht beispielsweise mit Fahrzeugbussen in Verbindung.The train bus is connected, for example, with vehicle buses.

Es sind dadurch zuverlässige Datenströme von den an den einzelnen Fahrzeugbussen angeschlossenen Komponenten über den Zugbus und das Fernübertragungsgateway zur Station für die Datenübertragung gegeben.This provides reliable data streams from the components connected to the individual vehicle buses via the train bus and the long-distance transmission gateway to the station for data transmission.

Beispielsweise werden Protokolle, die vom Zugbus oder vom Fahrzeugbus versandt werden, im Fernübertragungsgateway zur Übertragung umgeformt. Dadurch ist gewährleistet, dass eine zuverlässige Kommunikationsverbindung mit jeder Komponente des Eisenbahnfahrzeuges möglich ist, da das Fernübertragungsgateway von den Komponenten kommende Daten, die als Protokolle vorliegen, in eine zur Übertragung an die zweite Station geeignete Form bringt. Entsprechend macht das Fernübertragungsgateway von der zweiten Station aus am Eisenbahnfahrzeug eintreffende Daten für jede Komponente lesbar.For example, logs sent from the train bus or from the vehicle bus are converted in the remote transmission gateway for transmission. This ensures that a reliable communication link is possible with each component of the railroad vehicle, since the long distance transmission gateway brings data coming from the components, which are available as logs, into a form suitable for transmission to the second station. Accordingly, the remote transmission gateway from the second station makes data arriving on the railway vehicle readable for each component.

Beispielsweise befindet sich die zweite Station an einem festen Ort. Es kann sich dabei um einen Bahnhof oder um ein Stellwerk handeln.For example, the second station is at a fixed location. It can be a railway station or a signal box.

Beispielsweise ist die zweite Station in ein öffentliches Kommunikationsnetz eingebunden. Wenn ein ortsfestes öffentliches Kommunikationsnetz verwendet wird, sind keine neuen Verbindungen notwendig zwischen der zweiten Station und einer Sende- und Empfangsstation für Daten eines fahrenden Eisenbahnfahrzeuges. Es kann aber auch ein öffentliches Kommunikationsnetz genutzt werden, das auch fahrende Eisenbahnfahrzeuge erreicht, zum Beispiel ein Funknetz.For example, the second station is integrated in a public communication network. When a fixed public communications network is used, no new connections are necessary between the second station and a traveling railway vehicle data transmitting and receiving station. But it can also be used a public communication network, which also reaches moving railway vehicles, for example a radio network.

Mit dem Verfahren zur Übertragung von Daten wird insbesondere der Vorteil erzielt, dass einerseits eine ungewollte Übertragung von Daten an einen nicht zugelassenen Empfänger weitgehend ausgeschlossen ist und darüber hinaus Fehler in der Datenübertragung schnell und zuverlässig zu erkennen sind.With the method for the transmission of data in particular the advantage is achieved that on the one hand unwanted transmission of data to an unauthorized recipient is largely excluded and beyond errors in the data transmission can be detected quickly and reliably.

Ein Ausführungsbeispiel für das Verfahren nach der Erfindung wird im Folgenden näher erläutert:An embodiment of the method according to the invention is explained in more detail below:

Eisenbahnfahrzeuge eines Zuges sind über einen Zugbus miteinander verbunden. An den Zugbus sind über Gateways einzelne Fahrzeugbusse, die sich in den einzelnen Eisenbahnfahrzeugen befinden, angekoppelt. An die Fahrzeugbusse sind Komponenten angeschlossen. Beispiele für Komponenten sind die Antriebssteuerung oder die Bremseinrichtung. Zum Anschließen der Komponenten an einen Fahrzeugbus dienen Kommunikationsbusschaltungen.Railway vehicles of a train are connected to each other via a train bus. To the train bus, individual vehicle buses, which are located in the individual railway vehicles, are coupled via gateways. Components are connected to the vehicle buses. Examples of components are the drive control or the braking device. To connect the components to a vehicle bus are communication bus circuits.

Am Zugbus ist ein Fernübertragungsgateway, das Teil einer ersten Station zur Übertragung von Daten ist, angeschlossen. Ein solches Fernübertragungsgateway könnte auch an einem Fahrzeugbus angeschlossen sein.On the train bus is a remote transmission gateway, which is part of a first station for the transmission of data connected. Such a remote transmission gateway could also be connected to a vehicle bus.

Eine zweite Station zur Übertragung der Daten ist beispielsweise an einem festen Ort angeordnet und kommuniziert über ein öffentliches Netzwerk mit der ersten Station im Eisenbahnfahrzeug. Es sind verschiedene Funk-Netzwerke des öffentlichen Netzwerkes möglich, z. B. WLAN. Die zweite Station kann, wenn sie sich an einem festen Ort befindet, auch über ein Kabel-Netzwerk, an das sich ein Funk-Netzwerk anschließt, kommunizieren. Es kann in der zweiten Station z. B. ein Kommunikationsserver, ein Netzwerk aus Einzelplatzsystemen, ein Kommunikationsrouter oder eine Kombination aus diesen Komponenten vorhanden sein.A second station for transmitting the data is arranged, for example, at a fixed location and communicates via a public network with the first station in the railway vehicle. There are various radio networks of the public network possible, for. B. WLAN. The second station, when in a fixed location, can also communicate over a cable network followed by a radio network. It can be in the second station z. As a communication server, a network of single-user systems, a communication router or a combination of these components may be present.

Dass der Empfänger der gewünschte Adressat für die Daten ist, wird durch das Versenden einer Signatur festgestellt. Eine solche Signatur ist eine Zeichenfolge. Falls eine Signatur nicht korrekt sein sollte, werden die Daten nicht berücksichtigt und es kann zusätzlich eine Fehlermeldung abgegeben werden.That the recipient is the desired addressee for the data is determined by sending a signature. Such a signature is a string. If a signature is incorrect, the data will not be taken into account and an additional error message may be issued.

Es wird also nicht nur sichergestellt, dass nur bei den gewünschten Empfängern Daten empfangen werden, sondern es werden auch fehlerhafte Daten erkannt und dann nicht berücksichtigt.It is thus not only ensured that data is received only with the desired receivers, but also erroneous data are detected and then not taken into account.
