Definitions

  • the present invention relates to a method of controlling a railway vehicle running in automatic driving on a railway track shared in transmission zones, possibly independent of the cantons defined for the track circuits (at least, when these are of the “ without joint ”).
  • the receiver, on board the rail vehicle is connected to a voltage variation detector allowing it to precisely detect its passage over the transverse elements of the conductive turn disposed between the two rows of rails; in addition, a transmitter tuned to a second frequency is also on board and is arranged so as to induce a current in the rows of rails and, consequently, in the conductive turn so as to cause variations in the voltage induced in the turn , two other resonant circuits tuned to this second frequency being connected between the two rows of rails together with the first two.
  • the variations in the alternating supply voltage of the turn further constitute negative redundant information of the presence of a vehicle on the transmission zone.
  • This method has the particular advantage of using existing devices and superimposed on conventional track circuits.
  • it makes it possible to ensure, on board the vehicle, the necessary corrections to the odometers whose accuracy is required in automatic piloting, and to deliver, to the central control station, information making it possible to locate any vehicle at any time on one lane, with redundant information, which is very important if we want to reduce the distance between each vehicle.
  • Figures 1 and 2 schematically represent a device implementing the method according to the invention, device respectively installed on the ground and on board the railway vehicle.
  • a turn 6 is arranged between the rows of rails 1 and 2 in the immediate vicinity of the downstream shunt.
  • This coil 6 is supplied by a transmitter circuit comprising a generator 7 of alternating signals serving as a carrier wave for the information to be transmitted, connected to a modulator 8.
  • the modulated signals are applied to the coil 6 via a transformer 9 acting as an impedance adapter and circuit breaker.
  • the turn 6 therefore induces in the rails, an alternating signal which will be received on board the rail vehicle 16 entering the transmission zone, by means of the receiver part of the two transceivers 10 and 11 with which it is provided downstream of its front wheels 12, 13 forming a shunt via the axle 14.
  • the use of two transceivers is advantageous to allow operation in differential mode when receiving, therefore safer, edge.
  • the transmitting part of the on-board transceivers 10, 11 continuously transmits an alternating signal which is induced in the rails 1, 2 and, therefore, picked up by the coil 6.
  • An alternating signal generator 15 is onboard at this effect.
  • the operation of the control device is as follows:
  • a controlled limitation of the current delivered by the generator to the ground 7 allows, in addition to the protection of the equipment, to drop the supply voltage of the loop when approaching the rail vehicle.
  • the combination of these two positive and negative vehicle presence information allows a device on the ground to possibly interrupt the transmission in the transmission block, and to transmit in the downstream block while ensuring the continuity of the transmission for the on-board receivers.
  • the on-board receivers When the head of the rail vehicle 16 passes over each of the transverse parts of the turn 6, the on-board receivers are able to detect them with precision, and allow the rail vehicle to correct its location. Conversely, the passage of the on-board transmitters above the turn allows the device on the ground to accurately detect the position of the rail vehicle.
  • This logical information is transmitted respectively to the ground to a central control station 20, not shown, and, on board, to a local piloting unit 21. With such a method, the information transmitted over a determined area is only valid for the train. traveling in this area since the very presence of the train prevents the signals from spreading behind it. In fact, because there is no possible longitudinal crosstalk, it is possible to use only one frequency on the ground to supply the different turns 6 of the same railroad track.
