Definitions

  • the present invention relates to that of systems for managing the circulation of railway vehicles on the service tracks of a railway network.
  • Service tracks (such as the tracks in a marshalling yard or those in a depot) are portions of a rail network that are made up of a large number of sections of track.
  • FIG. 1 The attached figure shows, schematically, service tracks 10, equipped with a system for managing the circulation of railway vehicles 20 according to the invention.
  • the service tracks 10 constitute a portion of a railway network. They have different track sections, referenced 11 to 19 in the figure.
  • switch 6 connects section 16 on the one hand to section 11 and on the other hand to section 12; switch 7 connects section 16 on the one hand to section 17 and on the other hand to section 19; switch 8 connects section 17 on the one hand to section 18 and on the other hand to section 15; and the switch 9 connects section 19 on the one hand to section 13 and on the other hand to section 14.
  • a train 2 as an example of a railway vehicle, runs on the service tracks 10. In the figure, it is shown as running on the track section 11.
  • the rail vehicle traffic management system 20 is based on the implementation of a radiocommunication network respecting the LoRaWAN protocol (or more simply LoRa in what follows).
  • the LoRa protocol is a long-range, low-consumption radio transmission technology, more generally falling under LPWAN (“Low-Power Wide-Area Network”) communication technologies.
  • the LoRa protocol implements a modulation method making it possible to improve the range of communications compared to other radiocommunication protocols, for example the Wi-Fi protocol.
  • the LoRa technology enables communication over a range of over 2 km and up to 45 km in rural areas.
  • the topology of the radio communication network is star. There is a direct exchange of messages between a central node and peripheral nodes. Such a topology reduces the complexity of the operation of the radio communication network and the energy consumption.
  • the system 20 thus comprises a gateway 40 playing the role of central node of the radiocommunication network and a plurality of connected objects placed in the environment and respectively playing the role of peripheral nodes of the radiocommunication network.
  • the system 20 comprises a plurality of track devices.
  • Each track device is therefore a connected object integrating a LoRa radiocommunication interface.
  • These track equipment can be different types of signaling equipment. They may be, as in the figure, point motors. However, as a variant, they may also be pedals, for example hydraulic pedals, making it possible to detect the passage of a train, or even traffic lights, making it possible to visually communicate information to the train drivers.
  • pedals for example hydraulic pedals, making it possible to detect the passage of a train, or even traffic lights, making it possible to visually communicate information to the train drivers.
  • the state of a track device can be modified remotely by means of a control message addressed to it.
  • the figure thus represents, associated with the switch 6, a switch motor 26; at the switch 7, a switch motor 27; at switch 8, a switch motor 28; and at switch 9, a switch motor 29.
  • the switch motor 29 consists of a housing incorporating a motor 30, the actuation of which allows the change of the engagement state of the associated switch 9.
  • the motor 30 is connected to an electric power supply source.
  • the latter consists of a battery 32, which is advantageously rechargeable by a photovoltaic panel 34.
  • the switching motor 29 is then autonomous.
  • the routing motor 29 comprises a LoRa 39 radio communication interface allowing the exchange of messages with the gateway 40.
  • the LoRa interface 39 is connected to a computer 36 capable of interpreting the messages received via the LoRa interface 39 and of controlling the opening or closing of a switch 38 so as to allow the supply of the motor 30 by the battery 32 and consequently the change of position of the switch 9, that is to say the change of the switch engagement state 9.
  • the system 20 includes a server 42 associated with the communication gateway 40.
  • the communication gateway 40 constitutes a LoRa radiocommunication interface for communication with the communicating devices placed in the environment, in particular the track equipment.
  • the communication gateway 40 further comprises a WiFi or 3G / 4G mobile radio communication interface for communication with other communicating devices placed in its environment.
  • the system 20 comprises various devices making it possible to request the modification of the state of one or more pieces of equipment on the track.
  • a first embodiment of such a request device is given by a tablet 50 supplied to the driver of train 2.
  • the tablet 50 is equipped with a LoRa radio communication interface 51 allowing the exchange of messages with the gateway 40.
  • the tablet 50 constitutes a peripheral node of the LoRa radio communication network.
  • the radio communication interface 51 is a WiFi or 3G / 4G interface.
  • the tablet 50 displays a representation of the service channels 10.
  • the driver of train 2 selects a route according to the mission that train 2 has to accomplish. For example, while train 2 is on track section 11, the driver selects a route to take him on track section 13, via track sections 16 and 19.
  • switches 6, 7 and 9 must be placed in a required state.
  • the corresponding switch motors 26, 27 and 29 must therefore be actuated in order to place the switches which they control in the required state.
  • This request message is transmitted by radio between the radio communication interface 51 and the gateway 40.
  • Gateway 40 transmits the request message to server 42.
  • the server 42 executes software for managing the circulation of trains on the service tracks 10. This software is suitable for identifying all of the equipment to be the route and the states in which they must be respectively placed to respond to a route request message.
  • the server 42 determines to put turnout 6 in the left tilted state, turnout 7 in the right tilted state. and turnout 9 in the tilted right state.
  • the server 42 then transmits to each of the identified track devices a control message indicating the state in which it must place the turnout that it controls.
  • the various control messages are transmitted from the gateway 40 to the LoRa interfaces of each of the tracked equipment items identified.
  • the track equipment computer When receiving a command message addressed to it, the track equipment computer extracts from the command message the required state in which the turnout must be placed. If the turnout is not already in this state, the computer activates the engine so as to place the turnout in the required state.
  • the computer checks that the current state in which the switch is located actually corresponds to the required state.
  • a confirmation message indicating that the turnout is in the required state is produced by each piece of equipment on the track and transmitted to the server 42 via the LoRa radio communication network.
  • the server 42 collects the various confirmation messages so as to verify that each turnout of the route corresponding to the route is actually placed in the required state.
  • the server 42 prepares and transmits to the tablet 50, via the radio communication interface 51, a route opening message indicating that the route corresponding to the selected route has been opened.
  • the selected route is displayed as having been assigned to it and that the corresponding route has been opened,
  • the driver of train 2 moves train 2 forward on sight on the section track 11, then on section of track 16, then on section of track 19 and finally on section of track 13.
  • the tablet 50 comprises a means of geolocation, preferably by satellites, for example of the GPS type.
  • the tablet 50 loaded by the driver on board the train 2, determines its geographical position and consequently that of the train 2.
  • the tablet 50 periodically transmits a location message via the radio communication interface 51 to the server 42.
  • the server 42 determines, from the location messages that it receives from train 2, that a section of track has been crossed by train 2, it considers that this section of track is released and that it can be used. to open a route for the movement of another train.
  • a second embodiment of such a request device is given by a panel 52, said to be on the job, that is to say located in the immediate vicinity of the service roads 10.
  • the panel 52 incorporates a control interface.
  • LoRa radio communication 53 allowing the exchange of messages with the gateway 40.
