Definitions

  • the invention relates to a method for specifying permissible travel speeds for rail vehicles on rail systems divided into sections and protected by light signals.
  • the tracks of the rail system are usually divided into sections which may only be used by one vehicle group at a time.
  • the sections are preferably monitored for their free and occupied status by track circuits or axle counters.
  • Optical signals show an advancing vehicle group whether it is allowed to advance into a following section or not.
  • the specification of the highest possible driving speeds and short train follow-up times makes it necessary to give the vehicle associations, in addition to a stop and a driving concept, additional information about the maximum speeds permitted when advancing. This happens e.g. via so-called additional indicators; these are digital indicators for the large-scale visual representation of alpanumeric characters.
  • the object of the present invention is to provide a method according to the preamble of claim 1, which is suitable for minimizing the processing time of computers required for the provision and specification of speed values by optical signals. This task is solved by the features of claim 1.
  • Advantageous refinements of the method according to the invention are specified in the subclaims.
  • Fig. 1 shows a section of a track system with two tracks that can be driven in the same direction of travel.
  • the tracks are divided into track sections that are covered by light signals A to D. It is assumed that a train journey from signal A as starting point S of a route via signal B to signal D as destination point Z has been set. After entering the driveway, the signal definition should now take place, by means of which the vehicles or vehicle groups advancing to the start signal A are assigned the highest possible speeds of travel in order to clear the tracks as quickly as possible, but in the sense of securing those driving in front by means of the Target signal D covered vehicles may only be so high that the advancing vehicle group does not pass the target signal at too high a driving speed.
  • This table compares on the right-hand side as input parameters for various target speeds to be maintained on the target signal of the section under consideration on the left-hand side as corresponding entry speeds into the relevant section as output parameters.
  • a driving speed of 40 km / h is permissible on the signal B. This driving speed is shown on signal B.
  • the determination of the speed value permitted on the start signal of the relevant section also requires knowledge of the speed value permitted on the respective target signal, in the example assumed the target speed 0 for the target signal D.
  • the next light signal lying ahead of the direction of travel is determined, in the example of signal A.
  • signal B forms the section-specific target signal. Due to the distance between these two signals, the start and the target speed according to FIG. 3, line 3, are determined by table 1.
  • the speeds transmitted from the respective target signal to the start signal of a section not only serve to determine the permissible entry speed in each case, but can also be advantageously represented as distant signal terms for the signals following in the route.
  • the aim should be to use as few tables as possible, which can be used as universally as possible, for specifying different entry speeds to different target speeds.
  • the speed actually signaled must also include a maximum track-dependent speed permitted within the individual sections.
  • maximum line speeds lead to a reduction in the entry speed values from the tables, provided that they are above the maximum line speed.
  • Low maximum line speeds can be caused, for example, by slow travel points or by switches that are driven over their branching line.
  • the method according to the invention is advantageously implemented in an electronic signal box organized according to the area computer principle in such a way that the tables are stored in the area computers which are also oriented towards the target speeds to be observed at the end of the individual sections.
  • the references for selecting one or the other table can be stored in the control computers assigned to the signals or also in the area computers provided for controlling these control computers.
  • the individual light signals are assigned identifiers, for example in the form of numbers, under which the references assigned to them for the tables to be selected in each case are stored in the positioning computer or in an area computer.
