Definitions

  • the automatic train supervision system or ATS system (for "Automatic Train Supervision” in English), is implemented in an operational central office. It has different subsystems that allow a route to be assigned to each train and request the opening of a portion of that route in front of the corresponding train.
  • the ground ATC includes a zone controller, or ZC system (for "Zone Controller” in English), in particular responsible for monitoring the presence of each train on the network, the ATC board each train communicating regularly the instant position of the train.
  • ZC system for "Zone Controller” in English
  • the occupation of a zone is determined by the system ZC on the basis of the information it receives, on the one hand, from a primary system detection system and secondly a secondary detection system.
  • the secondary detection system is capable of redunding the primary detection system, in case, for example, the radio communication unit of a train no longer functions, the ZC system can not obtain the instantaneous position of the train.
  • suitable track equipment such as axle counters or track circuits, arranged along the track, the secondary detection system is able to detect the presence of a train in such and such area and to communicating a second occupancy information to the ZC system.
  • the ground ATC has received a message from the radar device indicating a movement of the train, the ground ATC indicates to the ATC board that the instantaneous position of the train is no longer known. Consequently, a phase of initialization of the instantaneous position of the train must be carried out before the ATC board can operate in the "active" operating mode.
  • the comparison of radar images is complex and leads to many false alarms, corresponding either to the detection of a movement of the train when it has in fact remained immobilized, or to the non-detection of certain associated events moving or unhitching the train.
  • the object of the present invention is to answer this problem by proposing an alternative solution to that of the document of the state of the art presented above.
  • odometry means for measuring a movement of the train
  • main calculator for measuring a movement of the train
  • radiocommunication means between the ATC edge and the ground ATC
  • the alarm unit the main computer being programmed to, in "standby" operating mode, verify that the movement of the train measured by the odometry means from a moment of switching from the "active" operating mode to the "idle” mode of operation is zero and, if so, transmit to the ground ATC an instantaneous position of the train using the radiocommunication means, at least at a time of switching from the "idle” mode of operation to the "active" operating mode.
  • the first subsystem 11 is located at a first end of the train 1, for example at the head end (the train 1 moving from right to left on the figure 1 ), while the second subsystem 12 is located at a second end of the train 1, for example a train tail end.
  • the first subsystem 11 comprises a main computer 18 advantageously connected, on the one hand, to a port of the first switch 15 and, on the other hand, to a port of the second switch 16.
  • the main computer 18 constitutes the computer of Train 1 edge and is suitable to be programmed to achieve different features.
  • the first subsystem 11 comprises odometry means. These means comprise at least one sensing element and an acquisition electronics 17.
  • the detection member is a sound wheel 23 consisting of a disc bearing a pattern and coupled to one of the wheels of the train 1 and an optical sensor coupled to a fixed part of the train 1 and able to detect the scrolling pattern worn by the disc.
  • the raw signal generated by the voice wheel 23 is applied to the input of the acquisition electronics 17 which is suitable for calculating a displacement quantity of the train.
  • the odometric means also comprise an antenna 24, for example of the RFID type, capable of picking up the signals emitted by positioning beacons installed on the ground, for example between the two rails of the track 2.
  • the signals received by the antenna 24 are transmitted to the acquisition electronics 17 which is able to process them to extract the information transmitted by a tag, such as an identifier of this tag, the location of this tag, etc..
  • the power supply of the edge ATC system 10 is effected by two low voltage supply lines.
  • the first power line 61 is connected via a converter 63 to the high voltage power supply line 65 of the train.
  • the second power supply line 62 is connected to a battery 64 adapted to, in case of interruption of the high voltage supply of the train, allow the operation of the edge ATC system 11.
  • the edge ATC system 10 can be placed in a standby mode of operation.
  • first and second subsystems 11 and 12 It is symmetrically for the first and second subsystems 11 and 12, first and second switches 15, 16 and 35, 36, the radiocommunication means 20 and 40, the alarm unit 21 and 41 , the main computer 18 and 38, and, among the odometry means, the voice wheel 23 and 43 and the acquisition electronics 17 and 37 of the signal delivered by the corresponding tone wheel.
  • Phase 100 which corresponds to the "active" operating mode, comprises a step 110, during which the ATC edge, for example the subsystem 11 determines the instantaneous position of the train from the signals received from the odometry means, that is to say both of the antenna 24 to recover the position of the last cross tag and the sound wheel 23 so as to determine the distance traveled since this tag has been crossed.
  • the ATC edge for example the subsystem 11 determines the instantaneous position of the train from the signals received from the odometry means, that is to say both of the antenna 24 to recover the position of the last cross tag and the sound wheel 23 so as to determine the distance traveled since this tag has been crossed.
  • the determined instantaneous position is stored in a random access memory of the main computer 18.
  • step 130 this updated instantaneous position is transmitted to the ground ATC via the radiocommunication means 20 and the radio communication infrastructure 7 on the ground.
  • the wakeup unit 21 requests the main computer 18 to check a number of conditions to allow the ATC edge to go to sleep. For example, it is verified that the train has no current mission to perform; that the instantaneous position of the train on the rail network corresponds to a siding (the main computer's random access memory 18 comprising a description database of the rail network); or that the train is stopped, that is to say that no movement is detected by the odometry means.
  • step 310 from the signals received from the voice wheel 23 and processed by the acquisition electronics 17, the main computer 18 determines a displacement d of the train since the last iteration of the step 310.
  • step 320 it is checked whether this displacement d is zero (possibly to a measurement margin close).
  • Steps 310, 320, 330 are iterated periodically.
  • phase 400 wake up train is initiated by receiving a control signal adapted by the wake up unit 21.
  • a wake-up command is produced during the phase 400.
  • the ATC sol reads the current value of the flag and compares it to the null value. If the flag is zero, indicating that train 1 was not moved while parked and its ATC board is in "standby", the ATC ground indicates in the wake up command that the ATC board can consider the value of the position of the train stored in the main computer 18 as the instantaneous position of the train to initialize the "active" operating mode.
  • the embodiment described in detail above makes it possible, at any moment, to verify the integrity of the train for example by circulating a bit of life along the first and second communication networks 13 and 14 between the first and second communication networks 13 and 14 and second subsystems 11 and 12, so as to ensure that the train communications networks are functional and therefore that the cars of the train are not disassembled.
  • This information as to the integrity of the train can advantageously be transmitted to the ground ATC at the same time as the position of the train, for example when the train wakes up.
  • the present invention has the following advantages: It offers increased availability, since the train when restarted is able to immediately know its precise instantaneous position and to circulate without manual intervention. This is particularly advantageous in the case of an unmanned automatic metro.
  • the ATC edge to be able to implement the method described above, is only slightly modified compared to those of the state of the art. It is simply a matter of defining the components that should be switched off when switching from "active" mode to "standby” mode and reprogramming the main computer so that it checks the movement of the train from information obtained by the sound wheel, and retransmitting periodically the position of the train as it has not moved or invalidate the position of the train as soon as it is moved.
