Use case / Anwendungsfall / Scénario d’utilisation

Site preparation data for Signal Controlled Warning Systems (SCWS); Daten zur Standortvorbereitung für signalkontrollierte Warnsysteme; nom descriptif en Francais

Description / Beschreibung / Description

An SCWS is a system used to warn working gangs on used tracks that a train is arriving and that they have to stop their work and leave the track area before the train is arriving and passing the working area. The SCWS-system is connected to the interlocking systems and has interfaces to mobile SCWS-equipment which is used by the working gang to announce the position of the gang and to be alerted if a train is approaching. The communication links between the mobile SCWS-equipment and the SCWS-system is realized either using cable-connections or using wireless networks (e.g. GSM-R).

For configuring of the different system-components site- and application-specific data are necessary. The site-specific data are infrastructure data which are used for the interlocking system, for the communication-network and data needed for the specific functions and the application. These data are used for the site-specific installation and for test-tools to verify the proper configuration.

Inputs: Inputs for the data preparation of a SCWS are the topology data from the interlocking system.

These interlocking data (IxL-data) describe

  • the track-topology
  • track-elements
  • block-information
  • speed limits in connection with specific elements of the track (especially switches)

Data needed by the SCWS in addition to the data used for the interlocking system (specific infrastructure data):

  • element lengths
  • allowed speeds on each element
  • the elements which are contained in each warning area
  • depending on the topology of the station the information about requests to / from a neighbor station to look for oncoming trains

Output: The sum of the data above

  • network-specific data
    • IP-addresses
    • ETCS-IDs

Characterizing Data / Charakterisierung der Daten / Caractérisation des données

The lengths of the elements are calculated from the mileages of the element-ends with consideration of error profile data. According to the error profile data lengths at certain mileage values are added or removed. The speeds are taken from the VzG (‚Verzeichnis zugelassener Geschwindigkeiten‘ = allowed speed for each track-segment). According to this speed profile the allowed speeds on an element is calculated. This includes speed changes on an element (necessary if signaling is done by ETCS and not with stationary signaling)

How often do the data change (update)?

The data are generated during installation of a SCWS and updated, if changes / updates of the infrastructure or the interlocking systems and peripherals are done (yearly or ‘pseudo’-static) in parallel to changes of preparation data for the interlocking systems. There are also changes possible or necessary due to operational findings, which force the change of specific parameters for track-sections to be done. There are no regular changes necessary.

Which views are represented by the data (focus)?

  • Signaling
  • Construction
  • Geometry
