Definitions

  • the present invention concerns railway vehicles that are equipped with one or more data buses for exchanging data between numerous components of the railway vehicle.
  • bus systems are inter alia used to transmit status and diagnosis data from the railway vehicle's subcomponents, such as traction or braking units, to a central diagnosis system, which is located for example in the driver's cab.
  • the driver of the railway vehicle can then visualise the diagnosis data in his cab via a corresponding display unit.
  • a railway vehicle comprising:
  • inventive railway vehicle may comprise one, several or all of the following features, in all technically feasible combinations:
  • FIG. 1 is a block diagram of a communication network according to the invention, including a railway vehicle's wired communication network, a wireless network and a plurality of remote back offices.
  • the figure represents a communication network 1 comprising a wired communication network 3, a wireless network 5 and an array 7 of remote back offices 9, 10.
  • the wireless network 5 may for example be a radio network using e.g. the GSM standard.
  • the remote back offices are preferably implemented in the form of remote servers 9, 10.
  • Each remote server 9, 10 communicates bi-directionally with the wired communication network 3 via the wireless network 5, as indicated by the arrows A.
  • Each remote server 9, 10 has a different function.
  • One remote server 9 may for example manage the seat reservation in the railway vehicle and exchange reservation data with the wired communication network 3.
  • the remote servers 10 (top and bottom of the figure) are diagnosis servers that receive or request diagnosis data from the wired communication network 3.
  • the reference sign U designates a common wireless interface with a single antenna and modem that is shared by four of the five remote servers 9, 10.
  • the wired communication network 3 is located in a railway vehicle.
  • the boundaries of the railway vehicle are represented by the dashed line 11.
  • the railway vehicle may for example be an electric multiple unit, preferably for passenger transport.
  • the wired communication network 3 includes a safety relevant data network 13 (identified by the solid line) and an information data network 15 (identified by the chain-dotted line).
  • 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.
  • safety relevant components 19 for safely operating the railway vehicle such as a traction or braking unit, are connected to the MVB 17. At least some of the safety relevant components 19 are adapted to provide status data about their operation. This status data is sent over the MVB 17.
  • a processing and diagnosing device 21 for controlling said safety relevant components 19, for receiving and processing said status data and for generating diagnosis data about the condition of the railway vehicle is also connected to the MVB 17.
  • the processing and diagnosing device 21 includes a main processing unit or MPU 21.1 and a driver display unit or DDU 21.2. Both the MPU 21.1 and the DDU 21.2 are connected to the MVB 17 via an MVB card 23.
  • the information data network 15 is used to distribute information data, such as traffic or seat reservation data, inside the railway vehicle. It preferably has a star topology with a central switch 25. It is preferred to implement the information data network 15 in the form of an Ethernet network.
  • the switch 25 is a central hub managing the communication between the various elements of the information data network 15. These elements are all connected to the switch 25, as indicated by the arrows F. Some of these elements are terminal information equipment 27, such as a dynamic passenger information unit or a video camera.
  • 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.
  • the information data network 15 also includes a receiving device 35 that is connected to the switch 25.
  • the receiving device 35 is a Passenger Information System controller or PIS controller.
  • the PIS controller 35 is configured for bidirectional radio communication with one of the remote diagnosis servers 10 and the remote servers 9.
  • the PIS controller 35 has a modem 37 and is connected to a radio antenna 39.
  • a diagnosis data requests relaying device 41 such as a specially modified MVB card, interconnects the PIS controller 35 and the safety relevant data network 13.
  • the MVB card 41 is adapted to relay a request for diagnosis data received by the PIS controller 35 from the remote diagnosis server 10 to the MPU 21.1 via the safety relevant data network 13, as indicated by the arrows P.
  • the MVB card 41 has a special design such that it is only able to send predefined and fixed messages, of which there only is a limited number of different ones, to the MPU 21.1 via the safety relevant data network 13.
  • the same includes a dedicated physical programming access port, which is the only way to reprogram the MVB card 41.
  • 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.
  • the function of the unidirectional security gateway 43 is to relay railway vehicle diagnosis data from said DDU 21.2 to the information Ethernet network 15.
  • said unidirectional security gateway 43 includes a Field-Programmable Gate Array or FPGA that is programmed to allow only unidirectional data communication from the DDU 21.2 to the information Ethernet network 15.
  • the same has a dedicated physical FPGA access port, which is the only way to reprogram the FPGA.
  • the communication network 1 is clearly split up into a first secure sub-network corresponding to the MVB network 13, and a second unsecure sub-network (indicated by the polygon 45 in solid lines) corresponding to the Ethernet network 15 and the wireless network 5.
