Definitions

  • the present invention relates to a receiving arrangement for speed control according to the preamble of claim 1 and to a related method according to the preamble of claim 7.
  • Known velocity controls in the railway field are also for example based on a travel time of a canton materialized by a track circuit: this control can be ensured by the lateral signaling which implements a device at the end of a track circuit.
  • train stop type to control the emergency braking of the train if it is out of the block before a countdown which has been started when the train entered the block. In this case, it is the total travel time of an area of several hundred meters that is evaluated, and therefore an average speed measurement is only possible over this long travel time. A quasi-instantaneous speed measurement in the vicinity of a point is therefore not possible by this device.
  • An object of the present invention is to provide a receiving arrangement for a simple speed control of a vehicle in the vicinity of a beacon transmitting electromagnetic signals and an associated control method.
  • Figures 1, 2 and 3 respectively present first, second and third embodiments of a receiving arrangement for the speed control of a vehicle (V) according to the invention.
  • the actual speed is thus measured as the actual average speed in the time range (dt). Knowing that the distance (D) between the receiving points is shorter than the length of the vehicle, or even a few meters, the actual speed measurement is thus advantageously almost instantaneous, and therefore more accurate.
  • each of the reception points (S1, S2) comprises a directional antenna, such as that of a beacon reader.
  • the second embodiment of the invention presented to the figure 2 provides that the two reception points (S1, S2) are two successively juxtaposed crossings of an induction circuit, each of said crossovers inducing a detectable change in polarity of the received signal.
  • a time interval (dt) is therefore easily deductible by the measurement of the time between changes in polarity at crossings.
  • the distance (D) between the polarity change points associated with said crossings being known, the actual speed of the vehicle can thus be determined instantaneously in the vicinity of the beacon.
  • the example of arrangement proposed in figure 2 provides that the crossings are simply formed by at least three turns (1, 2, 3) successively juxtaposed forming two crossings, one of the crossings materialized at the junction of the first two turns (1, 2) in the form of eight and the other materialized at the junction of the last two turns (2, 3) in the form of eight.
  • the crossings thus form the actual measurement points by change of polarity thus materializing the said reception points (S1, S2) formed by the two pairs (1, 2) and (2, 3) of crossed turns in the form of eight, the said couples having a common turn (2).
  • a third embodiment of the invention presented to the figure 3 provides that the two reception points correspond to variations in signal intensity at the passage of two successive loops of the same induction circuit above a beacon.
  • the two reception points (S1, S2) are two turns of a common induction circuit aligned on a tag reading axis (Ax), the rest of the circuit being offset with respect to this axis. .
  • the passage of a turn over a beacon induces a detectable change in intensity of the received signal, the signal being greatly reduced between the turns, because offset from the axis.
  • a time interval (dt) is therefore easily deductible by the measurement of the delay between the peaks of signal intensity.
  • the distance (D) between the turns being known, the real speed of the vehicle can thus be determined instantaneously in the vicinity of the beacon.
  • the receiving arrangement according to the invention also provides that at least three juxtaposed reception points can be envisaged, in order to deduce an acceleration component from the vehicle and / or to allow a redundant measurement. or refined speed.
  • a third beacon reader and its directional antenna would be added in juxtaposition of the other two readers / directional antennas (S1, S2) under a known distance with respect to each of the two readers.
  • the induction circuit can thus comprise four juxtaposed turns instead of three.
  • the induction circuit can thus comprise three loops aligned on the beacon axis instead of two.
  • the control method according to the invention provides that the on-board control unit compares the actual speed with a reference speed (for example dynamic, that is to say, taking into account the state of the railway signaling), the latter either from the beacon or from a separate source such as radio type or being an invariant (static reference speed value defined).
  • a reference speed for example dynamic, that is to say, taking into account the state of the railway signaling
  • the control method according to the invention can also provide that the on-board control unit compares the real direction of movement of the train (characterized by an order of passage of the characteristic points of the train on the beacon) with a reference direction, which can be an invariant or dynamically determined by railway signaling. More generally, the on-board control unit compares a reading order of the detection points with a reference direction of movement in order to detect the reverse movement on this beacon, this sense of reference either from the beacon or from a separate source such as radio type or being an invariant (static).
  • control method also provides that the control signal is an indication of actual speed or an alarm of overspeed or misinterpretation, sent either to the driver of the vehicle, or to a centralized control station by a source of communication such as than radio type.
  • the security scheme may provide for modulating the number of beacons on a vehicle path according to speed control requirements.
  • the method according to the invention is thus particularly well suited to such a scheme, because the vehicle will simply, rigorously and autonomously respect all these requirements at each crossing beacons.
  • the control method according to the invention makes it possible to enforce a security scheme providing for the provision of at least one beacon on a braking or stopping area of the vehicle.
  • the effective speed of the vehicle (VE) is thus suitably adapted to the path (x) of a vehicle at each beacon crossing.
  • the safety scheme comprises at least one maximum speed limit value (Vlim) as a reference speed for each beacon in order to limit overspeeds at various points along the path, and, if necessary, to trigger braking to be respected. (Vresp) or emergency or stop (B6) of the vehicle passing a beacon.
  • the control signal thus triggers, according to a pre-established safety scheme, an automatic adjustment of either the speed or an emergency braking of the train or even a stopping the vehicle, if the actual speed exceeds a speed limit depending on the reference speed.
  • the security scheme can also obey a degraded mode of a speed control system, for example CBTC type, allowing in particular in case of failure of a CBTC equipment to switch a speed control exclusively according to the said method, so to ensure maximum safety compliance.
  • a degraded mode of a speed control system for example CBTC type
  • the control method according to the invention is particularly advantageous for a construction vehicle without radio equipment or CBTC. It is indeed simple to have a receiving arrangement according to the invention coupled to an onboard unit (existing) measurement and speed control. This avoids installing on board the vehicle sophisticated and expensive equipment for speed control based on an odometer that counts the wheel turns, with a complex consideration of skid / slip effects because they may be vehicles of short length and / or with significant weight variations depending on their load. In addition, these vehicles may not have anti-skidding / jamming means adapted to odometry needs. Finally, a lack of space is possible to install the odometers or complementary means (radar, accelerometers, ...), as well as the required computers (ATC, radio). The receiving arrangement and the onboard speed measuring components according to the invention are compact and simple, and therefore form an adequate solution for construction vehicles.
  • the control method according to the invention provides that a beacon can be arranged on or at the periphery of a zone without radio equipment or CBTC, in order to simply and effectively meet the security criteria all types of vehicles with or without radio equipment or CBTC, on which however the arrangement for speed control (ie ie, the onboard reception points / on-board measurement and speed determination unit to be coupled to an existing speed control unit) according to the invention is provided.
