Definitions

  • the invention relates to an adapter device for a connection between at least one train protection device, in particular an ETCS train protection device, and a rail vehicle.
  • Modern rail vehicles nowadays include a train protection device on the vehicle side, by means of which they can be operated in a train protection system, such as ETCS—European Train Control System. It is necessary here for numerous signals, which can also include status information and commands, to be exchanged between the rail vehicle, in particular its vehicle controller, and the train protection device. Since there are many different vehicle architectures, for example due to different vehicle manufacturers and model series, it is usually necessary to adapt an interface on the vehicle so that the required signals arrive at the train protection device. In this case, a complex adaptation of the vehicle control technology or the vehicle software may be necessary. The structure and requirements for signals and interfaces are precisely defined by specifications such as TS I ZZS - Technical Specification Interoperability.

  • the adapter device comprises at least one vehicle interface, by means of which the adapter device can be connected to the rail vehicle for transmitting signals, at least one train protection interface, by means of which the adapter device can be connected to the train protection device for transmitting signals, and at least one signal processing device which is connected to both the vehicle interface and the train protection interface and which is used to process received signals from the vehicle interface and/or train protection interface and to provide signals at the Train protection interface and / or the vehicle interface is formed.
  • the solution according to the invention has the advantage that it can be easily connected in the rail vehicle between an existing communication interface of the rail vehicle and the train protection device to be connected.
  • the adapter device can be set up in such a way that the necessary signals for the train protection device are provided when corresponding signals are present at the vehicle interface.
  • the vehicle interface of the adapter device is designed in such a way that a large number of different vehicle types can be connected to it with their communication interface. For example, different types of vehicle buses or direct hardware wiring can be used for the connection.
  • the train protection interface of the adapter device is in turn designed for the train protection device to be connected in order to transmit the necessary signals in this way.
  • the train protection device is an ETCS train protection device
  • the type of interface as well as the protocol and the signals are precisely defined.
  • the adapter device according to the invention can be used both for retrofitting old vehicles and for new vehicles.
  • the adapter device can have at least one listening device arranged between the vehicle interface and the signal processing device, by means of which at least some of the signals received from the rail vehicle can be listened to without reaction.
  • This has the advantage that it is ensured that the signals received from the vehicle cannot be changed by the listening device. This simplifies a safety-related approval of the Rail vehicle that is equipped with the adapter device, or even makes a new registration superfluous.
  • the listening device can also be designed for reaction-free listening of signals from the vehicle bus of the rail vehicle.
  • a so-called data diode, also known as a data tap can be used as a monitoring device, for example, which can only monitor data traffic but does not change it. Interference-free eavesdropping is particularly suitable for retrofitting old vehicles, because re-registering the entire vehicle is not necessary or at least easier.
  • the signal processing device can only provide at least one predetermined signal to the train protection interface if one or more predetermined signals have previously been transmitted by the vehicle interface.
  • the at least one predetermined signal at the train protection interface can advantageously be designed in accordance with the ETCS specifications.
  • the train protection interface can be designed for connection to an ETCS vehicle computer. This has the advantage that the adapter device is set up for the ETCS standard without further adjustment and can be put into operation very quickly.
  • the ETCS standard is widespread throughout Europe, which means that a large number of vehicles can be retrofitted very quickly.
  • the adapter device can have at least one display interface, by means of which the adapter device can be configured to be connected to an additional display device for transmitting display signals.

  • another display device such as For example, an ETCS display can be easily connected.
  • the adapter device In order to be able to connect further devices to the adapter device according to the invention, it can have at least one further interface, by means of which the adapter device is designed to transmit signals for automatic train control, for completeness of the train, for ETCS Level 3, for the condition of the route and/or for diagnosis.
  • the invention also relates to a retrofit kit for a rail vehicle with at least one train protection device, in particular an ETCS train protection device, and an adapter device for a connection between the train protection device and the rail vehicle.
  • the adapter device is designed according to one of the aforementioned embodiments.
  • the invention also relates to a rail vehicle with at least one communication interface, with at least one train protection device, in particular an ETCS train protection device, and with an adapter device for a connection between the train protection device and the communication interface, the adapter device being designed according to one of the aforementioned embodiments.
  • the rail vehicle 1 is connected to the vehicle interface 6 of the adapter device 3 via its communication interface 5 .
  • this connection is divided into one or more bidirectional cable connections 9 and at least one serial unidirectional connection 10 .
  • This serial connection 10 can be designed, for example, as a CAN-BUS, MVB-BUS or as another serial connection.
  • the serial connection 10 is unidirectional in that only data flows in the direction of the adapter device 3 . In contrast to this, the data or signals can be exchanged in both directions via the cable connection 9 .
  • the interface referred to here as communication interface 5 can be designed in different ways. It is usually present in known rail vehicles 1 and is used for data communication with a vehicle controller (not shown) of rail vehicle 1 . A large number of signals can be exchanged via the serial connection 10 . In contrast to this, a specific signal is always transmitted via the cable connections 9 . Particularly important signals, such as e.g. B. a driving direction activation, transmitted via a cable connection 9, because the exclusivity ensures a high level of security. Since the train protection device 4 has to communicate with the vehicle controller when the rail vehicle 1 is in operation, the adapter device 3 must be connected to it. In this case, the communication interface 5 is used for this purpose.
  • the existing communication interface 5 of the rail vehicle 1 essentially does not have to be changed for the use of the adapter device 3 according to the invention.
  • the communication interface 5 is designed for wired communication. This is also an advantage for security reasons. Theoretically, however, wireless communication from the adapter device 3 to the communication interface 5 and thus to the vehicle controller of the rail vehicle 1 would also be conceivable if this were to be used in rail vehicles in the future, for example.
  • the adapter device 3 is also connected to the train protection device 4 via a further serial connection 11 between the train protection device 4 and the train protection interface 7 on the adapter device 3 .
  • the train protection device 4 is designed as an ETCS train protection device, specifically as an EVC—European Vital Computer.
  • the European Vital Computer is a so-called safe vehicle computer in the European train control system ETCS.
  • the EVC is responsible for carrying out a large number of important actions while the rail vehicle 1 is traveling, for example compliance with braking curves.
  • Other safe tasks include e.g. B. the distance and speed monitoring and the processing of ETCS driving permits (Movement Authority) .
  • the serial connection 11 is designed on the basis of existing normative interface requirements in accordance with the ETCS standard, as specified, for example, in accordance with UNIS IG subset 119 and subset 139.
  • the UNIS IG - Union Industry of Signaling is an associated member of the railway industry association UNI FE and prepares specifications for ETCS.

  • these cable connections 12 are designed unidirectionally in the direction of the communication interface 5, so that signals or data are transmitted.
  • the adapter device 3 also includes a listening device 13 , by means of which the data transmitted via the serial connection 10 can be listened to in a reaction-free manner.
  • a listening device 13 can also be referred to as a data tap or data diode.
  • signals and data are processed and forwarded.
  • the signal processing device 8 collects the existing data and signals, in particular from the communication interface 5 , evaluates them and generates output signals, either in the direction of the communication interface 5 or the train protection device 4 .
  • signals are made available via the serial connection 11 in the form of the standardized protocol in accordance with the ETCS specifications.
  • the signal processing device 8 includes a software-based projection interface (not shown) with which the adapter device 3 can be adapted.
  • a software-based projection interface (not shown) with which the adapter device 3 can be adapted.
  • ready-made settings with ready-made data sets for different vehicle types can be present which only has to be selected.
  • the data sets can include different instructions or rules according to which the input signals are processed into output signals. In this way, adaptation to different vehicle types can be accelerated and facilitated.
  • the signal processing device 8 could of course also be adjustable via hardware switches. However , this is rather unusual today .
  • the input signals can also be evaluated in such a way that even if certain input signals are not present, corresponding output signals can nevertheless be set. For example, several predetermined signals at the communication interface 5 can result in the signal processing device 8 reporting a specific signal to the train protection device 4 via the serial connection 11, although this is not directly apparent from the signals received. Since the signal processing device 8 can be programmed, it can also carry out intelligent evaluations. So could the train protection device 4 z. B. expect a signal that the rail vehicle 1 is moving. Such a movement status is z. B. not displayed on the communication interface 8 in the existing type of rail vehicle 1 . But it will z. B. a current speed is displayed. The signal processing device 8 could then be designed in such a way that the movement signal is reported to the train protection device 4 when the speed is not equal to zero.

  • the adapter device 3 has the advantage that it provides the required signals for the train protection device 4 independently of the type of rail vehicle 1 . This can be advantageous in particular when retrofitting the train protection device 4 on older rail vehicles 1, because the signals present at the already existing communication interface 5 of the rail vehicle 1 can be used without changes to the vehicle controller.
  • the signal processing device 8 of the adapter device 3 can be prepared for a large number of different vehicle types, so that only the corresponding data set on the signal processing device 8 has to be selected during assembly and commissioning.
