Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • an in DE-OS 34 31 171 described track vacancy detection device provides the combination of the track sections adjacent to a defective metering point into a single longer track section (see page 11, lines 3 to 8).
  • the majority of the counting errors can be corrected without redundant devices such as e.g. additional axis detectors must be kept available.
  • This simple three-section correction requires three consecutive free track sections to be carried out. It is improved by further developments of the invention specified in the subclaims to an extended three-section correction, in which, as claimed in claim 2, the correction can also be carried out if one of the three track sections has already been occupied by a subsequent train and / or if as provided in claim 3, the last of the three sections has not yet been cleared.
  • a railway line S is shown schematically, which is divided into track sections by metering points ZP1, ..., ZP4 equipped with computers.
  • a number of axle counting computers assigned to several track sections reads out internal memories of the metering point computers, which contain a current number of axles and the direction of passage of the last registered axis, at regular intervals and manages a net counter A1, ..., A3, for each track section whose counter reading he added changes in the number of axes stored in the counting points delimiting the track section, depending on whether the section is entering or leaving the section with a positive or negative sign.
  • a certain target counter reading (e.g. the counter reading "0") is a prerequisite for a free notification of the respective track section.
  • the track section delimited by the metering points ZP1 and ZP2 is assigned the net counter A1
  • the net counters A2 and A3 belong to the track sections which are delimited by the metering points ZP2 and ZP3 or by the metering points ZP3 and ZP4.
  • FIG. 1 a also shows an error pattern that has arisen as a result of a positive incorrect count of + d axes at the metering point ZP3.
  • the net counters A2 and A3 have been adversely affected by this incorrect count.
  • the at point of delivery ZP3 incorrectly counted additional axes, moving in the direction of travel R, resulted in a negative deviation -d from the target meter reading (O) in the net counter A2, in the net counter A3 they left an excess of + d after clearing the assigned track section.
  • the net counter A1 of the track section first traveled remained unaffected.
  • a correction of the status of the net meters is permitted. It always starts from the net meter, which after clearing the associated track section has a meter reading that is lower than its target meter reading. Such a negative deviation from the target counter reading is a clear criterion for an incorrect count, since other operational events or faults cannot cause negative counter readings and, for example, it can be excluded that a train increases its number of axles while traveling. After a negative meter reading of a net meter is determined, the meter readings of the net meters of the neighboring sections are checked.
  • the net meter which, after the associated track section has been cleared, has a positive deviation from its target meter reading, which corresponds to the amount of the negative deviation of the net meter of the neighboring section, may also be corrected, since this is almost certainly due to the incorrect count.
  • a correction could only be out of place here and lead to a dangerous free message if at least one further metering error at an adjacent metering point and a train separation were present at the same time. Such a case is so unlikely that it can be excluded.
  • the location of the incorrect count is always the point of delivery at which the track sections whose net counters show an opposite deviation from their target counter readings adjoin each other.
  • the correction is made by adding the missing count d to Status of the net counter showing the negative deviation from the target counter reading and by deducting the shortfall d from the reading of the net counter showing the positive deviation from the target counter reading.
  • FIG. 1b shows the distance S corresponding to FIG. 1a with a negative incorrect count at the point of delivery ZP2.
  • the counter readings of the net counters A1 and A2 have been changed due to the insufficiently counted axes of a train traveling in the direction of travel R.
  • the net counter A2 has the negative counter reading of -d, which is decisive for the admissibility of a correction, while the net counter A1 shows a positive remainder d of the same amount and the net counter A3 shows the unchanged target counter reading. The same applies here to the correction as to the case described in connection with FIG. 1a.
  • the described three-section correction corresponds to the security of the "symmetrical four-correction" described in the journal article mentioned at the beginning, but only requires three free track sections to be able to be carried out.
  • the three-section correction can be expanded.
  • the net counter A1 of the neighboring section lying in the direction of travel shows a position Y above its target counter reading
  • a check is carried out to determine whether a previous clearance message and its occurrence by counting axes in the direction of travel R is stored. If this is the case, a correction is made in accordance with the method described in connection with FIG. 1a, since the counter reading Y is due to a new occupation of the section via the counting point ZP1.
  • the status of the net counter A1 remains unchanged, the net counter A2 receives the shortfall d corresponding to the counting error and the net counter A3 receives the amount d deducted.
  • the adjacent track sections are combined into virtual track sections after metering points have failed, the contents of the net counters of the track sections which form the new subsections of the virtual track section are entered into a new net counter assigned to the virtual track section.
  • the virtual track section can then be treated like an ordinary track section.
