Definitions

  • the invention relates to a method for operating a drainage system and a control device for such a drainage system according to the preamble of the independent method claim 1 and the independent device claim 8 (see for example the DE 28 52 784 A1 ).
  • a method for operating a technical draining plant in which a Talbremse is controlled so that processes reach a directional track brake of a direction track with a threshold below speed, for example, from the above, generic forming DE 28 52 784 A1 known.
  • Other methods or control devices are from the DE 30 05 675 A1 or even the DE 11 66 811 A known.
  • the present invention has for its object to provide a method for operating a technical draining plant, which allows even further automation of the operation of the drainage system and, associated therewith ultimately an increase in their performance.
  • This object is achieved by a method for operating a rangierischen drainage system, wherein in a first mode of operation, a downdraft brake is controlled such that processes in the form of expiring cars or groups of cars reach a directional track brake of a direction track with a speed below a first threshold, characterized in that is switched from the first operating mode in a second operating mode, if for an expiry a running target is determined in or in front of the directional track brake of the direction track, and in the second operating mode the valley brake is controlled so that the run reaches the determined running target in or before the directional track brake at a speed below a second threshold.
  • a valley brake is thus controlled in such a way in a first operating mode that the sequences reach the directional track brake of the respective direction track at a speed which falls below a first threshold value.
  • a changeover to a second operating mode takes place in the event that a running target in or before the directional track brake of the directional track is determined for a sequence. This means that even before the process actually reaches the valley brake, it is recognized that the sequence will at least not completely pass through the directional track brake as planned. This has the consequence that based on the relevant process, the braking performance of the directional track brake is not or at least not fully available for braking the process.
  • the valley brake is controlled in the second operating mode such that that the process reaches the determined running target in or before the directional track brake at a speed below a second threshold. This means that in the second operating mode, in contrast to the first operating mode, the control of the valley brake takes place in such a way that it is braked relative to the respective running target and not relative to the respective directional track brake.
  • the control of the valley brake or the speed influencing of the sequence through the valley brake is carried out in such a way that the sequence reaches the determined running target at a speed which falls below the second threshold value.
  • the second threshold may typically be about 1.5 m / s, since this is a common target speed for the impact of a run on a stationary car.
  • the first threshold value in the first operating mode will typically be approximately 4 m / s, since this is a standard value for a permissible intake speed in a directional track brake in practice.
  • the method according to the invention is therefore already characterized by the fact that an automatic operation of the drainage system is also permitted in the event that a directional track is filled into or over the respective directional track brake. Not only is an occupancy or use of this area permitted at all, but moreover, by switching from the first operating mode to the second operating mode and the changed control of the valley brake in the second operating mode, an automated operation of the drainage system continues to be enabled.
  • trains can be formed in an automated form by means of the drainage or train formation system whose length exceeds the useful length of the respective directional track, so that the car column formed by the individual processes in the region of the directional track brake or in extends the area in front of the directional track brake, that is, between the valley brake and the directional track brake.
  • the method according to the invention will generally be carried out specifically for the respective directional track so that a changeover from the first operating mode to the second operating mode is effected specifically for the respective directional track.
  • processes which are intended for another, not yet completely filled directional track, further treated according to the first mode of operation such that the valley brake is controlled so that the operations reach the respective directional track brake at a speed below the first threshold.
  • the valley brake and the directional track brake can each be designed as a single brake element or in the form of several brake elements, that is, as a brake relay.
  • the method according to the invention is switched from the first operating mode in the second operating mode, provided that a run target is determined in or before the directional track brake of the directional track for the process taking into account a Gleis Stahlsprognose and / or a shredding list.
  • a run target is determined in or before the directional track brake of the directional track for the process taking into account a Gleis Stahlsprognose and / or a shredding list.
  • the corresponding sensors can be, for example, track circuits for track free length measurement, wheel sensors for determining the occupancy state of track sections or even radar sensors for distance measurement.
  • the dismantling list is usually provided by a dispatching system and, in addition to information about the destination of the respective process or to the directional track in which the respective process is to be provided, for example, also contain information on the type and length of the individual cars. In particular, from a combination of the track level forecast with information of the shredding list can thus be detected comparatively precise and early overcrowding or emerging overfilling of the directional track.
  • the method according to the invention is configured such that in the second operating mode the valley brake is controlled in such a way that the operations are slowed down to a slower discharge speed from the valley brake compared to the first operating mode.
  • the control of the valley brake in the second mode of operation is aimed at ensuring that the respective sequence reaches the determined running target in or before the directional track brake at a speed below the second threshold. In comparison to the first mode of operation, however, this usually has the immediate result for processes with comparable running characteristics that in the second operating mode the discharge speed from the valley brake is lower than in the first operating mode.
  • the speed of the processes in the area behind the valley brake in the second operating mode is usually about 1.5 m / s to about 2 m / s, while in the first operating mode, the speed of the processes in this area usually at least will be about 3.5 m / s.
  • the method according to the invention can also be configured in such a way that in the second operating mode the valley brake is controlled in such a way that further sequences intended for the directional track achieve a specific target determined for the respective further sequence with a speed that falls below the second threshold.
  • a running target is determined specifically for each sequence and this running target is taken into account in the control of the valley brake.
  • the running target which can also be referred to as a destination, "wander" by running further for the directional track certain processes always in the direction of the professionberg, ie in the direction of the valley brake.
  • the respective travel destination can be determined, for example, by summing the lengths of subsequent processes based on a track fill level prognosis of the direction track or the information that this is occupied up to the directional track brake and thus specifically or individually for each further course determined for the particular direction track Running goal is calculated.
  • the method according to the invention is furthermore designed in such a way that in the second operating mode the valley brake is controlled in consideration of sequence data specific to the respective sequence.
  • specific expiration dates such as the weight or rolling resistance of one expiration, in the second Operating mode in their consideration, a particularly accurate and reliable control of the valley brake and thus ultimately enable the entire drainage system.

  • certain processes in the second operating mode for the directional track in question, certain processes generally have a lower speed in the area behind the valley brake than those sequences which are intended for another directional track not already completely filled.
