Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • Axle counting devices are mainly used in railway systems where long distances between train stations have to be bridged or where track construction reasons, e.g. exclude the use of steel sleepers, the use of track circuits.
  • a known problem with axle counting devices is the occurrence of counting errors which prevent the free signaling of a track section, which presupposes a tie between the number of axles moved into the track section and the number of axles moved out of the track section, and thus lead to operational inhibitions.
  • a number of methods for automatic counting error correction are also known, which enable subsequent release of a track section that has been cleared but is still occupied as a result of a counting error.
  • DE-OS 15 30 389 DE-PS 17 80 469 and DE-OS 19 38 311 circuits which compare the counting results of axle counting points with counting results of more distant axle counting points and subsequently release a section of the route reported as occupied due to a counting error if from this comparison it can be concluded that a counting error must exist and a train separation is no longer the reason for the busy signal.
  • a second postage reporting level can be formed, for example, by axis reporting points arranged at the beginning and at the end of a route.
  • GB-A-2 164 184 discloses a method for track vacancy detection in a railway installation with the features according to the preamble of claim 1.
  • the method according to the invention provides for a counting error of an axle counting point to be corrected as a function of the counting result of two further axle counting points, which may be the two closest points of delivery in the direction of travel or the two points of origin immediately behind in the direction of travel.
  • a correction is only made if in the first case the result to be corrected is lower than that of the following metering points and in the second case the incorrect result is larger than that of the previous metering points.
  • the deviation of the count result to be corrected cannot be caused by a train separation, because in both cases the number of axles has increased, which is only possible through a positive change in train length or through a counting error. If no shunting movements take place in the area under consideration, a positive change in train length is also ruled out as the cause.
  • the correction takes place here independently of any signal box information and, since the two "reference points of delivery" always lie directly next to each other on one side of the point of delivery to be corrected, can be carried out as soon as two successive track sections are cleared. If one uses the usual metering point distances and block lengths today, one can hardly speak of an operational disability.
  • a further development of the method according to the invention described in claim 2 provides for the marking of the route of a train with the aid of the influenced metering points. This makes it possible to change the route of the train, e.g. through a turnout area, to be held and treated as a line-like route with regard to the correction of counting errors.
  • the figures show sequences of meter readings from the metering point memories assigned to the individual metering points, the heights of which are shown here without an exact numerical value, relative to the meter readings of the neighboring axle metering points.
  • 2a shows the state of an unused, declared route, the point of reference memory of which all have the same counter readings, e.g. take the counter reading O.
  • a correction may only be made if train separation can be excluded with certainty.
  • a positive change in train length does not occur in practice, as long as shunting movements can be excluded.
  • a correction is permissible if three successive metering points have the constellations shown in FIGS. 1a and 1b.
  • the meter reading of the third metering point memory seen from the left to the right in the direction of travel, can immediately be adjusted to the meter reading of the two preceding metering point memories, since it must be based on a positive metering error - excluding positive train length changes. Train separation cannot lead to an increase in the number of axles, so it did not happen here.
  • the first point of delivery counted an insufficient number of axes, because both subsequent points of delivery have registered a higher number of counts. A train separation cannot have taken place, since the two points of delivery influenced last have not found any loss in the number of axles.
  • Correction may also be made here and the deviating lower counter reading of the first metering point memory may be increased to the meter reading of the two following metering point memories. In contrast to case 1b, in which the correction is carried out immediately, it can only be corrected here if the track section delimited by the following two metering points has cleared.
  • the counter reading configurations shown in FIGS. 1c to 1f represent case examples in which a correction was made or omitted using the configurations shown in FIGS. 1a and 1b.
  • 1c is the correction of a positive counting error.
  • Fig. 1e shows a train separation with a simultaneous counting error. A correction must not be made because it is not clear which of the meter readings (fourth or fifth from the left) is falsified. Neither of the constellations that permit correction (FIG. 1a or 1b) occurs here.
  • Fig. 1f shows the case of a train separation with positive counting error, in which the counting error is corrected, but the train separation is documented on the basis of the different meter readings of the metering point memories 3 and 4 (counted from the left), and the track section in between remains occupied.
  • the constellation of the counting point memories 4, 5 and 6 is decisive here, which corresponds to the case in FIG. 1b.
  • FIG. 2 illustrates a train journey over a route equipped with metering points.
  • a train entering the route (Fig. 2a) from the left first increases the count of a point of delivery memory assigned to the first point of delivery, then that of the second, third and so on point of delivery memory (Fig. 2b and 2c).
  • the metering point memory located in the direction of travel is deleted, ie reset to the value set before the train journey (FIG. 2d). Since this occurs at every point of delivery on the route traveled, the train journey, as can be seen in FIGS. 2e and 2f, can be followed on the computer until the train has left the route section and all the point of delivery memories have the value set before the train journey.
  • each train journey can be documented without the need for signal box information and for this a signal box interface must be created.
  • each route can be treated as a simple route by a switch area equipped with metering points. Correction of counting errors can then be carried out without any problems, as described above.
  • the counting pulses delivered by the metering points are advantageously stored in separate metering point memories for correction and for marking the route.

  1. Procédé de signalisation de voie libre d'une installation ferroviaire, dans lequel à l'aide de points de comptage disposés sur la voie, le nombre et le sens de passage des essieux parcourus sont déterminés dans un résultat de comptage, dans lequel la libération du bloc de voie situé entre ces points de comptage d'essieux est déterminée grâce à la comparaison des résultats fournis par les points de comptage d'essieux qui se succèdent dans le sens de la marche, dans le cas où la comparaison indique une coïncidence, et dans lequel la correction des erreurs de comptage est effectuée par un ordinateur recevant tous les résultats de comptage de tous les points de comptage d'un tronçon de voie comportant plusieurs blocs, où
    chaque point de comptage situé le long du trajet d'un train fournit des impulsions de comptage qui sont comptés par l'ordinateur en fonction du sens de la marche et le résultat du comptage est mémorise, caractérise par le fait que
    pour procéder à la correction des erreurs de comptage on réalise une égalisation du résultat d'un comptage erroné par rapport aux résultats de deux points de comptage, seulement lorsque ces deux points de comptage correspondent aux points de comptage qui succèdent audit point dans le sens de la marche et que leurs résultats sont identiques entre eux et ont une valeur supérieure à celui à ajuster, ou si ces deux points de comptage précèdent immédiatement ledit point de comptage dans le sens de la marche et que leurs résultats sont identiques entre eux et ont une valeur inférieure à celui à ajuster.
  2. Procédé selon la revendication 1, caractérisé par le fait que le trajet du train est enregistré par l'ordinateur et que dans ce but les résultats de tous les points de comptage d'essieux influencés par le train sont d'abord mémorisés et ensuite effacés, lorsque le point de comptage d'essieux suivant dans le sens de marche, a constaté un résultat de comptage identique et par le fait que les points de comptage, dont les résultats ont été mémorisés et ensuite effacés, restent enregistrés dans l'ordinateur et servent à caractériser le trajet du train.
