Definitions

  • the safety relevant data network 13 has a safety relevant data bus 17.
  • the safety relevant data bus 17 is a Multifunction Vehicle Bus or MVB.
  • the information data network 15 also includes a transmitting device 29 that is connected to the switch 25.
  • the transmitting device 29 is a transceiver with a modem 31.
  • the transceiver 29 is connected to a radio antenna 33 so that it can communicate wirelessly with one of the remote diagnosis servers 10.
  • a unidirectional security gateway 43 interconnects the DDU 21.2 and the Ethernet network 15. As indicated by the arrows K, the unidirectional security gateway 43 allows data communication from the DDU 21.2 to the information Ethernet network 15 but prevents any data communication from the information Ethernet network 15 to the DDU 21.2.

Claims (3)

  1. Schienenfahrzeug (11), Folgendes umfassend:
    - eine sicherheitsrelevante Komponente (19) für den sicheren Betrieb des Schienenfahrzeugs, wie beispielsweise eine Zug- oder eine Bremseinheit, wobei die sicherheitsrelevante Komponente (19) dafür eingerichtet ist, Statusdaten über ihren Betrieb bereitzustellen,
    - eine Verarbeitungs- und Diagnostiziervorrichtung (21) zum Steuern der sicherheitsrelevanten Komponente (19), zum Empfangen und Verarbeiten der Statusdaten und zum Erzeugen von Diagnosedaten über den Zustand des Schienenfahrzeugs (11),
    - ein sicherheitsrelevantes Datennetzwerk (13), das einen Multifunktionsfahrzeugsbus oder MVB (17) beinhaltet, der die sicherheitsrelevante Komponente (19) und die Verarbeitungs- und Diagnostiziervorrichtung (21) miteinander verbindet,
    - ein Informations-Ethernet-Datennetzwerk (15), das sich von dem sicherheitsrelevanten Datennetzwerk (13) unterscheidet, zum Verteilen von Informationsdaten, wie beispielsweise Verkehrs- oder Platzreservierungsdaten, in dem Schienenfahrzeug (11), wobei das Informations-Ethernet-Datennetzwerk (15) außerdem eine Empfangsvorrichtung (35) beinhaltet, die für eine bidirektionale Funkkommunikation mit einem entfernten Backoffice (10) konfiguriert ist,
    - eine Diagnosedaten-Anfragenweitergabevorrichtung (41), die dafür angeordnet ist, die Empfangsvorrichtung (35) und das sicherheitsrelevante Datennetzwerk (13) miteinander zu verbinden, wobei die Diagnosedaten-Anfragenweitergabevorrichtung (41) eine MVB-Karte ist, die dafür eingerichtet ist, eine Anfrage nach Diagnosedaten, die durch die Empfangseinheit (35) von dem entfernten Backoffice (10) empfangen wird, an die Verarbeitungs- und Diagnostiziervorrichtung (21) über das sicherheitsrelevante Datennetzwerk (13) weiterzugeben, wobei die MVB-Karte (41) nur dazu in der Lage ist, vordefinierte und feststehende Nachrichten, von denen nur eine begrenzte Anzahl unterschiedlich ist, über das sicherheitsrelevante Datennetzwerk (13) an die Verarbeitungs- und Diagnostiziervorrichtung (21) zu senden, und die einen zugeordneten physischen Programmierungszugangs-Port beinhaltet, der der einzige Weg zum Neuprogrammieren der MVB-Karte (41) ist,
    - eine Übertragungsvorrichtung (29) zum Senden von Daten von dem Schienenfahrzeug (11) an das entfernte Backoffice (10), wobei die Übertragungsvorrichtung (29) Teil des Informations-Datennetzwerks (15) ist, und
    - ein Gateway (43), welches das sicherheitsrelevante Datennetzwerk (13) und das Informations-Datennetzwerk (15) miteinander verbindet,
    wobei das Gateway (43) ein unidirektionales Sicherheits-Gateway ist, das eine Datenkommunikation von dem sicherheitsrelevanten Datennetzwerk (13) zu dem Informations-Datennetzwerk (15) gestattet und jegliche Datenkommunikation von dem Informations-Datennetzwerk (15) zu dem sicherheitsrelevanten Datennetzwerk (13) verhindert, wobei das Gateway (43) ein FPGA (Field-Programmable Gate Array) ist, das einen zugeordneten physischen FPGA-Zugangs-Port aufweist, welcher der einzige Weg zum Neuprogrammieren des FPGA ist,
    wobei das unidirektionale Sicherheits-Gateway (43) dafür eingerichtet ist, die Diagnosedaten von der Verarbeitungs- und Diagnostiziervorrichtung (21) an das Informations-Datennetzwerk (15) weiterzugeben, und
    wobei die Übertragungsvorrichtung (29) dafür eingerichtet ist, die verzögerten Diagnosedaten von dem Schienenfahrzeug (11) an das entfernte Backoffice (10) zu senden.
  2. Schienenfahrzeug (11) nach einem der vorhergehenden Ansprüche, wobei die Übertragungsvorrichtung (29) und/oder die Empfangsvorrichtung (35) dafür eingerichtet sind, drahtlos, insbesondere über Funkwellen, mit Hilfe zum Beispiel des GSM-Standards, mit dem Backoffice (10) zu kommunizieren.
  3. Schienenfahrzeug (11) nach einem der vorhergehenden Ansprüche, wobei das Schienenfahrzeug ein Elektrotriebwagen ist, vorzugsweise für den Passagiertransport.
