Definitions

  • the vehicle is equipped with a travel counter which evaluates wheel signals from travel pulse generators arranged on the axles and thus on the vehicle side a current value for the distance traveled so far or the distance between the current vehicle position and a reference point on the route side provides. Sliding and skidding of the wheels can lead to errors that require regular synchronization of the travel counter.
  • the vehicle-side displacement measuring devices are basically synchronized in that the line conductors are provided with electrical markings at regular intervals and that the passage of these markings is detected.
  • the markings consist of an intersection of the line conductors (Eisner's Taschenbuch der Eisenbahntechnik 1975, Dr. Arthur Tetzlaff-Verlag Frankfurt / M., Pages 179-181).
  • the change in the phase position of the line conductor current in the vehicle-side receiving antennas coupled to the line conductors is used for the synchronization of the vehicle-side displacement measuring devices.
  • an advantageous embodiment of the invention provides that levels are only received and / or evaluated during evaluation time windows whose position and width are determined by the respective track cut length and the joint geometry is determined.
  • Figure 1 is used to explain a line-shaped train control with remotely powered, coded audio frequency track circuits (FTGS), which is explained in the article mentioned in SIGNAL + DRAHT 84 (1992), 6.
  • a track section GST comprises rails S1, S2, between which separating joints TS1, TS2 are arranged. The separating joints are spaced apart according to a track section length GAL and delimit the track section GA.
  • the track section GA is followed by a track section GA 'lying in the direction of travel A and a preceding track section GA ", the other side limitation of which is formed in each case by a corresponding separating joint (not shown in FIG. 1).
  • the vehicle FZ has antennas ANT1, ANT2, which are arranged and connected in a known manner, for receiving the telegrams TEL transmitted via the rails S1, S2 for influencing the vehicle.
  • a first evaluation unit AUSW1 is connected to these antennas via a pre-filter VF1 and provides data telegrams DTEL prepared on the output side for further processing by a vehicle-side computer (channel 1).
  • FIG. 3 shows the signal level (channel 1) of the received telegrams TEL in the upper area. According to the feeding of the Tele ⁇ programs opposite to the direction of travel A ⁇ and the short-circuit effect of the axis ACH disappears this signal level when the S-connector from the antennas ANT1, ANT2 is passed.
  • the level reception via the receiving unit EE channel 2 with the antenna ANT3 is shown.

Abstract

Le compteur de distance (WZ) détermine à partir d'un point de référence (BZ) la distance parcourue (S) sur une section de voie (GST) divisée par des joints de séparation (TS1, TS2) présentant chacun au moins une portion de conducteurs électriques (L1, L2, L3) perpendiculaire aux voies (S1, S2), ces conducteurs servant à acheminer des courants de voie spécifiques à un tronçon de voie dans des tronçons successifs (GA, GA', GA''). Un dispositif récepteur (EE) embarqué, conçu pour recevoir des niveaux (P1, P2, P3) assure une synchronisation précise, lesdits niveaux étant produits par des courants (QS) perpendiculaires aux voies. Une unité d'évaluation (AUSW2) fournit un point de référence actualisé (BZ') lors de la réception des niveaux.
