Definitions

  • the invention relates to a device for detecting the occupied or free state of a track section with Minim ⁇ least at a vehicle-side transmitter and trackside receiver pairs at the ends of the track section angeord- net and in each case in the track direction spaced first and second receiver, said receiver Passage of the vehicle receive signals from the transmitter and are connected to an evaluation device.
  • the track vacancy detection is an essential decision ⁇ criterion for control of points and signals.
  • the de ⁇ decision is made on whether a rail vehicle may enter in this section of track or not Based on the occupancy status of the track sections.
  • the goal is in principle the prevention of collisions of vehicles by driving or flanking. For this purpose, it must be ensured that in each case only one vehicle is located in a defined section of the route. Other vehicles are the entrance into the ⁇ sen occupied by a vehicle track section to deny. This is the classic task for a signal box.
  • the Stell ⁇ plant requires this backup technical information, which occupied track sections and which are free.
  • the invention has for its object to overcome these disadvantages and to provide a Gleisokomelde appealing of the generic type, in which an increase in the coupling range is detected promptly, so premature free ⁇ message of a still occupied track section can be avoided.
  • the object is achieved in that a ⁇ speaking the receiver during the passage at a coupling range between the transmitter and the receiver plus a maximum distance, which results from a minimum pulse duration of the receiver and a maximum line speed is set in such a way, that an error in the coupling range results in an overlap of the response of the receiver of the receiver pair results.
  • a ⁇ speaking the receiver during the passage at a coupling range between the transmitter and the receiver plus a maximum distance, which results from a minimum pulse duration of the receiver and a maximum line speed is set in such a way, that an error in the coupling range results in an overlap of the response of the receiver of the receiver pair results.
  • the vehicle passage is carried out a check of the track free reporting device on critical increase of the coupling range.
  • An additional effort for regular on-site ⁇ measurement of the current coupling range is eliminated. Maintenance measures of this kind are not required, with a particular advantage of the claimed solution being that timely error disclosure is possible.
  • the receivers are connected in accordance with claim 3 with a fail-safe evaluating one signal box, wherein an AND operation is provided with respect to the activations Chen the two receivers of a receiver pair.
  • the interlocking gets redundant Informatio ⁇ nen, empowered by the normally safe for signaling purposes From ⁇ evaluation within the signal box the required high safety in the track vacancy detection.
  • the AND operation makes it easy to determine whether both receivers generate output information at the same time.
  • FIG. 1 shows the most important components of a train detection system according to the invention
  • Figure 3 is a layout diagram of the receiver and whose activa ⁇ tion.
  • Ends 2 and 3 each have a receiver pair with receivers El and E2 is arranged.
  • the receivers El and E2 When passing through a vehicle 4 (Figu ⁇ Ren 2 and 3), the receivers El and E2 generate output signals which are fed to a signal box 5 for evaluation.
  • the vehicle 4 is equipped with a transmitter S1 which continuously transmits transmission telegrams which are received by the trackside receiver El in the area of a coupling range Di.
  • the simplifying assumption that the coupling is symmetrical, which means that the coupling begins when the Sen ⁇ the Sl has approximately half coupling range Di / 2 to the receiver El, and ends when the transmitter Sl to half by more than the Coupling range Di / 2 is located behind the receiver El.
  • the response of the receiver El ie the output duration of the output signal corresponds to the duration of the coupling plus a time t 0 , during which time t 0 a maximum of one
  • This relationship is illustrated in FIG. Figure 3 shows a constellation with redundant transmitters Sl and S2, both transmitters Sl and S2 are arranged on the vehicle 4 seen in the direction of travel next to each other.
  • the receiver El and E2 are able to distinguish transmit message ⁇ programs from the transmitters Sl and S2.
  • the data telegrams from the first transmitter Sl are only from the first receiver El and the data telegrams from the second transmitter S2 can only be evaluated by the second receiver E2.

Abstract

L’invention concerne un dispositif de détection de l’état occupé ou libre d’une section de voie (1), comprenant au moins un émetteur (S1, S2) côté véhicule et des paires de récepteurs côté ligne, disposées aux extrémités (2, 3) de la section de voie (1) et comprenant respectivement des premier et second récepteurs (E1, E2) espacés dans le sens de la voie (10), les récepteurs (E1, E2) recevant des signaux de l’émetteur (S1, S2) lors du passage du véhicule (4) et étant reliés à un dispositif d’analyse. L’objet de l’invention est de garantir une affectation exacte entre les extrémités de section de voie (2, 3) et la position momentanée du véhicule. A cet effet, dans le cas d’une portée du couplage (D 1, D 2) entre l’émetteur (S1, S2) et le récepteur (E1, E2) en plus d’un parcours maximal (D 0) découlant d’une durée d’impulsion minimale (t 0) des récepteurs (E1, E2) et d’une vitesse maximale de parcours (v max), une réponse des récepteurs (E1, E2) pendant le passage est réglée de telle sorte que lorsque la portée du couplage (D 1, D 2) augmente à cause d’une erreur, les réponses des récepteurs (E1, E2) de la paire de récepteurs sont superposées.
