Automatic Schemaexport for Element switchIL

Autoexport from the XML-Schema for element IL:switchIL of railML® version 3.1
Documentation The switch is a track asset where a train can change from one track to another. Here the functional aspects for interlocking operation are considered.

Attributes:
  • preferredPosition: This is the preferred position of the switch which it is switched to when not in use or in case of both positions required for flank protection. (optional; xs:string)
Possible values:
  • right
  • left,

  • maxThrowTime: Maximum time in milliseconds during which the IL can drive the element. If it has not reached end-position before this timer expires, the interlocking stops throwing as to prevent damage. (obligatory; xs:duration),

  • typicalThrowTime: typical throw time is the average time it takes between the moment the IL receives the call and the element reaches the new position. Switch throwing adds a delay to route setting that is of great interest to the use case simulation. For this purpose, we add an attribute typicalThrowTime that allows capacity planners to estimate the influence of slow throwing switches on train traffic. Note that this excludes controller (OCS) processing time and communication between controller (OCS) and interlocking. (optional; xs:duration),

  • returnsToPreferredPosition: The automatic normalisation attribute is closely related to the preferred position. Whether or not the IL returns the element to its preferred position depends on this parameter. E.g. a derailer that is modelled as ... preferredPosition=engaged autoNormalisation=true ... will return to its engaged position when released. A switch modelled as preferredPosition=right autoNormalisation=false... will not automatically return to the right position when released. This combination of attributes is useful for geographical interlockings that automatically determine the preferred routes given the preferred position of intervening switches. (optional; xs:boolean),

  • isKeyLocked: One of boolean true or false. True means that the switch is clamped either mechanically or by any electric or electronic means. The interlocking shall never attempt to throw a clamped switch. (optional; xs:boolean),

  • numberOfBladeSwitchActuators: number of switch actuators controlled from interlocking to throw the switch blades, 0 means no direct operation from the interlocking (optional; xs:nonNegativeInteger),

  • numberOfFrogSwitchActuators: number of switch actuators controlled from interlocking to throw the frog nose(s), 0 means no movable frog (optional; xs:nonNegativeInteger),

  • id: unique identifier (optional; xs:ID; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|\{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\}); compare: Dev:Identities
*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
