Definitions

  • the invention relates to a device for detecting the occupancy or free status of a track section by means of a track comprising both rails of the track section track circuit, in which a transmitter feeds a transmission signal, which is supplied via the track circuit at least one receiver.

  • the presence of a rail vehicle in the track section is revealed by the receiver receiving no or a weaker signal from the transmitter for a defined time. Since ⁇ can be easily identified with the transmission signals from the receiver with a free track section, a high transmission voltage and there ⁇ desirable with a high transmission power.

Abstract

L'invention concerne un dispositif permettant de déterminer si une partie de voie ferrée est libre ou occupée, au moyen d'un circuit de voie (1a, 1b, 1c, 1d; 7a, 7b) comprenant un des deux rails de la partie de voie ferrée, dans lequel un émetteur (2, 8) achemine un signal émis, ce dernier étant envoyé par l'intermédiaire du circuit de voie (1a, 1b, 1c, 1d; 7a, 7b) à au moins un récepteur (3, 9). L'objectif de l'invention est de surveiller une partie de voie ferrée plus longue. A cet effet, le circuit de voie (1a, 1b, 1c, 1d; 7a, 7b) présente des condensateurs (4) mis en parallèle entre les rails.
