Definitions

  • the invention relates to a device and a method for locating a railway vehicle along a railway equipped with a beacon system and more particularly to a device for the precise and punctual localization of a vehicle. Rail compared to a beacon transmitting an electromagnetic signal for the transmission of information.
  • the invention also relates to an antenna intended to equip a railway vehicle in such a device.
  • the document FR-A-2,713,754 discloses a radiant-powered system of ground beacons for communication with an on-board antenna on a railway vehicle.
  • a system of beacons to locate the railway vehicle on the track punctually by knowing the location of the beacon that is crossed by the antenna on the vehicle. rail. Such a location is usually done by analyzing the power of the signal picked up by the antenna, matching the moment when the signal picked up by the antenna is maximum with the moment when the antenna is located above the beacon.
  • the object of the present invention is therefore to propose a device and a method for locating a railway vehicle which makes it possible to locate the railway vehicle precisely and precisely with respect to a system of beacons, in particular of the EUROBALISE type, and which is simple and economic to achieve.
  • the invention relates to a device for the localization of a railway vehicle along a railway equipped with a beacon system, the beacons being intended to transmit information to the vehicle by the transmission of a electromagnetic signal, the vehicle comprising an antenna having a first receiver circuit for sensing the electromagnetic signal emitted by the beacon which is crossed by the antenna, characterized in that the antenna comprises a second receiver circuit in the form of an eight-loop to precisely determine when the antenna is centered on the beacon.
  • the subject of the invention is also a method for spot localization of a vehicle equipped with a device according to any one of the characteristics described above, characterized in that the phase change of the signal delivered by the second circuit is detected. receiver relative to the signal delivered by the first receiver circuit to deduce the moment when the antenna is centered on the beacon.
  • the invention further relates to an antenna for sensing electromagnetic waves emitted by a beacon, the antenna comprising a first receiver circuit in the form of a simple loop for receiving the information communicated by the beacon, characterized in that it comprises a second loop-shaped receiver circuit in eight for precisely determining when the antenna is centered on the beacon.
  • the antenna is embedded on a railway vehicle and cooperates with beacons in accordance with the EUROBALISE standard.
  • the figure 1 represents a device for spot localization of a railway vehicle on a railway track comprising ground installations which consist mainly of beacons 2, of a type known per se, provided with their control electronics and fixed along the railway line in known locations.
  • the locating device also comprises equipment on board the rail vehicle which consists mainly of a receiving antenna and an evaluation unit 6.
  • the evaluation unit 6, which may be a calculator, is powered by its own converter and is connected to the antenna 1.
  • the antenna 1 is located under the vehicle at a location such that the antenna 1 passes in the axis of the beacons 2 when the train is traveling on the railway.
  • the beacons 2 comprise a transmission circuit provided with a transmitting loop intended to emit electromagnetic waves representative of the information to be transmitted to the vehicle.
  • the beacons 2 are powered by radiation from an onboard transmitter by the antenna 1 of the railway vehicle, the latter providing the energy necessary for the operation of the beacon 2 which is crossed by the railway vehicle.
  • This electrical power supply of the beacon 2 is made for example by integrating into the beacon an antenna circuit provided with a receiver coil connected in series with the primary of an isolation transformer, the secondary of the latter being connected to the circuit of the issue of the beacon.
  • the tags 2 comply with the European standard EUROBALISE, that is to say they ensure the communication by magnetic coupling with the antenna 1 of the vehicle in the frequency band 3.9 - 4.5 MHz, these beacons having the advantage of being compact, with a length of about 50 cm and light, with a weight about 5 kg.
  • the antenna 1 of the vehicle comprises, in a manner known per se, a first receiver circuit 3 which is constituted by a single loop.
  • the first receiver circuit 3 is intended to pick up the signal transmitted by the beacon 2 and is connected to the evaluation unit 6 of the vehicle which analyzes the information transmitted by the beacon 2 crossed by the antenna 1.
  • the antenna 1 also comprises a second receiver circuit 4 which is constituted by a loop in the form of eight, the latter being substantially concentric with the simple loop of the first receiver circuit 3.
  • the second receiver circuit 4 is also connected to the evaluation unit 6 of the vehicle.
  • the size of the loop in eight is close to the size of the transmission loop of the beacon 2 in order to achieve an optimal accuracy on the location of the antenna 1.
  • the beacon 2 When the vehicle approaches a beacon 2 and the transmitter of the antenna 1 of the vehicle is in the contact zone of the beacon 2, that is to say that the energy level captured by the beacon on the ground is sufficient to ensure its operation, the beacon 2 emits an electromagnetic signal representative of the information to be transmitted.
  • This signal is picked up by the antenna 1 of the vehicle and in particular by the loop forming the first receiver circuit 3.
  • the power of the signal picked up by the first receiver circuit 3, as a function of the movement of the antenna 1 carried by the vehicle following the X axis, is represented on the figure 3 .
  • the first receiver circuit 3 of the antenna 1 delivers a signal S 3 which is maximum over a relatively wide range which is centered on the contact zone of the beacon 2, the signal thus captured being able to be favorably used by the signal unit.
  • evaluation 6 to analyze the information transmitted by the beacon 2.
  • the amplitude of the signal varies to cancel at the beginning and at the exit of the contact zone with however the presence of side lobes, of part and other of the contact area.
  • the signal emitted by the beacon 2 is picked up by the second receiver circuit 4 of the antenna 1.
  • the power of the signal picked up by the second receiver circuit 4 as a function of the displacement of the antenna 1 along the axis X is represented on the figure 4 .
  • the second receiver circuit 4 delivers a signal S 4 which varies in amplitude at the beginning and at the end of the contact zone of the beacon 2 and which is zero in the center of the contact zone, that is to say when the point The crossing of the loop in eight is centered on the transmitting loop of the beacon 2.
  • the signal S 4 also has side lobes on either side of the contact zone.
  • the spot localization method according to the invention therefore consists in detecting, with the aid of the evaluation unit 6, the phase change of 180 ° between the signal delivered by the second receiver circuit 4 and the signal delivered by the first receiver circuit 3, in order to deduce the moment when the antenna 1 is centered on the tag 2.
  • Such a location method makes it possible to identify the moment when the antenna 1 is centered on the tag 2 with a accuracy less than ⁇ 5 cm and therefore to locate the vehicle on the track punctually with a precision of the same order.
  • the location of the antenna 1 with respect to the beacon 2 will be validated only if the signal emitted by the beacon 2 contains an informational message, the unit d evaluation 6 thus verifying that the detected phase change is accompanied by the reception of a clear message by the first receiver circuit 3 to validate the location.
  • the security of the location method can also be enhanced by setting a voltage threshold in order to filter out any inadvertent phase changes that may appear on the existing side lobes at the ends of the beacon contact.
  • Such a device associated with such a method thus has the advantage of allowing a one-off registration, at the passage of each beacon, of the railway vehicle on the railway with an accuracy of less than ⁇ 5 cm, and this while retaining a standard type beacon.
  • EUROBALISE very widespread on railway networks.
  • the device and the locating method according to the invention thus make it possible, simply by equipping the railway vehicles with an antenna according to the invention, to very economically obtain a very good accuracy on the points of registration of the vehicle on the track. railway.
