Definitions

  • the field of this invention is rail traffic management, in particular the need to maintain train integrity and to ensure that a track is clear.
  • Train integrity devices indicate to the driver and/or the controller that the train is complete and that a part of the load has not become divided from the train. Apart from many other contexts, this information is of vital importance to both the driver and the controller and control systems, to establish that a part of the train was not left on a track section before the next train is authorized into that track section.
  • Train movement authorization has historically been controlled by the issuing of track warrants.
  • RTO Radio Train Order
  • TCO Train Control Officer
  • UHF 450-470 Mhz
  • Authorizations are given orally and are recorded on paper by both the TCO and the driver.
  • TWS Track Warrant Systems
  • TWS a computer is used to issue the authorizations (warrants).
  • Train integrity completeness of the train has been established by various systems of which some are independent of trackside equipment.
  • air monitoring i.e. the air brake system, which uses either positive or negative gauge pressure
  • This can indicate to the driver that his train is intact, or that a part of the load has become divided or detached from the train.
  • Another system is to use a GPS on the last wagon and a GPS on the locomotive and obtaining a measure of the distance between the co-ordinates of these two devices.
  • This system is, however, subject to low accuracy of the GPS, and the intact train length is variable according to geographic factors.
  • the GPS coordinates are subject to an accuracy limit of from 5 to 15 metres; the length of the train can stretch or crimp by up to 10% (which could be up to 20 metres on a 200 wagon train) due to movement in the couplings according to whether the train is being pulled uphill by the locomotive or is being held back by the locomotive while going downhill; and finally, the length of the train reported by the GPS is equal to the distance between the GPS co-ordinates but this is not correct while the train is negotiating a curve.
  • the present invention provides a method of reporting presence or absence of train integrity which comprises selecting a spot on a track, detecting the coordinates of that spot, storing those co-ordinates, detecting the GPS co-ordinates at the end-of-train (EOT), comparing the EOT GPS co-ordinates with the spot co-ordinates and reporting a train integrity if and only when the EOT GPS coordinates match the spot co-ordinates.
  • the method of the invention preferably includes detecting the co-ordinates of the selected spot by using a GPS at the cab or locomotive (front) of the train.
  • the selected spot will be a spot at which the cab or locomotive is located at the moment the spot is selected.
  • the integrity report can be given using this method at any required position and as often as may be required, in the course of the passage of a train along a track or track section.
  • the track clearance signal can be sent from any point on a track where radio contact is available, by voice communication between the driver and the controller.
  • the track clearance signal can be generated automatically using the computerised track warrant system.
  • the advantage of the system of the invention is that the reliability of the signal is independent of the geographical conditions that have been discussed above.
  • the use of the invention can give the critical information that is required when a train is moved onto a sideline or passing loop, for another train to pass on the main track.
  • a useful feature is that the system can, however, be used at any chosen position and is independent of geographic factors in any case.
  • the invention thus makes provision for a GPS located at the end of train (EOT), means to record the GPS co-ordinates of a selected spot, means to transmit the GPS co-ordinates generated by the GPS at the EOT and means to compare these co-ordinates.
  • a GPS is preferably located at the cab or locomotive at the front of the train where the driver is, to provide the spot so- ordinates.
  • This means would include computer hardware and communication means, with suitable implementing software and communication protocols.
  • the invention may also provide means to generate a report of track clear when the GPS signals are identical and to relay that to the driver and preferably also to the controller.
  • the GPS equipment can also provide information as to speed and direction, in addition to position and this information can be useful for the controller as supplementary information.
  • the length of the train can be calculated from the time delay between the two GPS signals and the speed of the train, using an integral calculation, if the speed is varying during the time delay period.
  • the speed and direction can also be given.
  • the speed and direction can again be given and compared.
  • figure 1 is schematic plan view of a train, in the first step of the method
  • figure 2 is a similar view of the train, at the moment when the track clear signal is enabled by the system.
  • the cab 1 of the train 2 has just passed the clearance mark and entered the loop 3, a loop which is provided to allow the main line 4 to be open for other passing trains.
  • the GPS co-ordinates of the position 5 are noted/record£d ⁇ by-a.-GP- -located n..the-cab- A "train, .length- .request-message" containing the co-ordinates is sent to the GPS receiver in the EOT.
  • the GPS unit in the EOT starts measuring the length of the train by calculating the distance the EOT is travelling, using the speed and time inputs from the GPS receiver in the EOT, until the EOT reaches the clearance mark at the position 5.
  • the GPS unit in the cab also measures the length of the train by calculating the distance the cab is travelling, using the speed and time inputs from the GPS receiver in the cab, until a track clear message is received from the EOT having reached the clearance mark at the position 5.
  • the EOT 6 has just reached the clearance mark at the position 5 and the GPS located in the EOT has detected GPS co-ordinates which match those noted/recorded by the GPS in the cab. This match generates a track clear message, since for the match to occur, the EOT must have passed the clearance mark of the loop at position 5.
  • the track clear message contains the length of the train as calculated by the EOT.
  • the train length measurement of the EOT and the cab is terminated by the track clear message.
  • this independent calculation can confirm train integrity.
  • the track 4 is thus confirmed to be clear and open for other traffic.
  • the cab unit will generate an alarm to indicate that either the train is not complete or the equipment is faulty.

Abstract

L'invention concerne un procédé de confirmation de l'intégrité d'un train au moyen d'un équipement GPS. Le procédé est caractérisé par les étapes consistant à sélectionner un point sur une voie, à détecter les coordonnées de ce point, à stocker ces coordonnées, à détecter les coordonnées GPS de fin de train (EOT), à comparer ces coordonnées GPS EOT avec les coordonnées du point, et à reporter l'intégrité d'un train, si et seulement si, les coordonnées GPS EOT correspondent aux coordonnées du point. Les coordonnées du point sont de préférence détectées par un GPS supplémentaire situé dans la cabine de conduite ou dans la locomotive située en début de train. Ainsi, lorsque les coordonnées GPS de fin de train correspondent aux coordonnées du point, il s'avère que la fin du train est également passée sur ledit point.
