Definitions

  • the subject of the invention is that of methods and systems for managing the movement of a vehicle on a railway network.
  • vehicle any vehicle able to move on a rail network, such as a train, a tram, a subway.
  • a railway network is composed of different basic objects, such as a section of track with two end points, a section of track with three end points or switching points, a signaling element, and so on.
  • each object is in a state of engagement taking a particular value among a plurality of possible, predefined values.
  • an interlocking logic has been used to allow the safe movement of a vehicle along a network road.
  • the interlocking logic is implemented at centralizing equipment level, hereinafter called the central control unit, which controls the latching state of all the constituent objects of the network.
  • the interlocking logic uses a route table which presents, for each possible route, the values of the interlocking states of the objects constituting this route which must be simultaneously checked to allow a safe movement of the vehicle on the considered route.
  • the definition of the route table is a compromise between flexibility and operational possibilities, technical feasibility and cost, while considering the interlocking between the movements.
  • the central control and manages the movement of all vehicles traveling at any given time on the rail network.
  • this architecture does not allow an easy update of an existing railway network. For example, the replacement or addition of an object must be followed by the rewrite of the route table and its qualification before its integration at the central control.
  • the invention aims to overcome the aforementioned problems.

  • the planning by the central control 31 of the movement of a train comprises the development of a mission file which is then transmitted to the train controller.
  • the management by the traffic controller of a train is carried out by implementing a protocol for allocating, engaging and then releasing the necessary resources directly from the ROCs with which they are associated.
  • the on-board controller authorizes the safe movement of the train on a path composed of the resources allocated to the train and allowing it to continue the mission assigned to it.
  • a resource of the network 10 is associated with a single ROC but, alternatively, several resources 10 may be associated only one ROC.
