Definitions

  • the present invention relates to a device for transmitting information by rails between a railway track and a set of vehicles traveling in the same direction on this track, along which a plurality of information transmission zones succeed one another.
  • the present invention relates to an improvement made to such a device which has been described in particular in the European patent application published under the number 0 007 271.
  • the series resonant circuit tuned to the carrier frequency connected between the two rows of rails at each end of a transmission zone is constituted by two identical series resonant circuits arranged in parallel and each comprising a capacitor in series with the primary winding of a transformer, the secondary windings of the two transformers being connected in series and in opposition, so that an alternating signal at the carrier frequency appears across the circuit thus formed when the two circuits resonant series have different characteristics.
  • the circuit 51 constitutes the series resonant circuit connected between the two rows of rails 1 and 2 (at one end of an information transmission zone in accordance with the aforementioned European patent application.
  • the circuit 51 must have a substantially zero impedance for the alternating signal por both the information of the area it closes.
  • the circuit 51 is constituted by two series resonant circuits connected in parallel and each comprising a capacitor 101 and 102 and the primary winding 103 and 104 of a transformer.
  • the secondary windings 105 and 106 of the two transformers are connected in series and in opposition and the circuit thus formed is connected (or its terminals 110) to a control center not shown.
  • an alternating signal whose frequency is equal to the carrier frequency appears at terminals 110 if the characteristics of one of the two series resonant circuits undergo a modification and, in particular, if one of the two circuits is interrupted or if a component causes the resonant frequency of one of the two circuits to be derived.
  • circuit 42 corresponds to a series resonant circuit connected upstream of a zone and circuit 51 corresponds to a resonant circuit connected downstream of the immediately adjacent zone.
  • the carrier frequencies of the two immediately adjacent zones being different, the resonant frequencies of the circuits 42 and 51 are different. This has the advantage of being able to appreciate the crosstalk or, more precisely, the ratio of the useful current to the current coming from the adjacent zone.
  • the signal collected at terminals 110 is an alternating signal of the same frequency as that of the signal which was applied to terminals 72.
  • the resonance frequency of any of the resonant circuits formed by the capacitors 101, 102, 201, 202 respectively in series with the primary windings 103, 104, 203, 204 is modified, the signal collected at terminals 110 will have a frequency different from that of the signal which was applied to terminals 72 and this difference will be representative of the faulty resonant circuit.
  • the signal collected at terminals 110 is the sum of a signal at frequency f and a signal of frequency F1 according to the faulty resonant circuit of circuit 42, or the sum of the signal at frequency f and a frequency signal F2 according to the faulty resonant circuit of circuit 51.
  • each of the resonant circuits of circuits 51 and 42 is connected to the rail lines by different cables.
  • the cables 198 and 199 are coupled with the turn 62 in the form of a frame and connected to the generator 32 of the signals carrying information.
  • the transformers of circuit 51 for example each have a second secondary winding 210 and 211.
  • This signal collected at the terminals 212 makes it possible to control the carrier signal emitted in the turn 62 and the good condition of the cables connecting the circuits 51 and 42 to the rails.
  • the coupling of the cables 198 and 199 with the turn 62 is necessary to keep a correct signal at the terminals 212 when a train, passing to the right of the connection to the rails, short-circuits the latter.
