  • Patent number: 10471978
    Abstract: Controlling a level crossing includes one or more transceivers located in proximity of a level crossing area on a first side of a railway track; corresponding passive reflective targets located in proximity of the level crossing area on a second side of the railway track opposite to the first side where each transceiver is located and a control unit connected to each transceiver. Each target is arranged to receive RF signals coming from each transceiver and to send back corresponding reflected signals. Each transceiver is arranged to elaborate said reflected signals to calculate predetermined parameters values. Also, the control unit is arranged to acquire said parameters values from each transceiver and to elaborate them to detect the presence of a train in an area around the level crossing area and, in case of presence of said train, to send a warning message and/or close bars of the level crossing.

  • Patent number: 10449983
    Abstract: A method for commanding a railway level crossing protection system comprising: a) activating a railway signal preventing a train from driving beyond a level crossing; b) detecting an incoming train approaching the level crossing and measuring a speed of said incoming train; c) calculating a waiting time, as a function of the train's measured speed; d) waiting until expiration of the calculated waiting time and, once said waiting time expires, sending an order to commute the protection system into the protected state; and e) querying the state of the protection system and if said protection system is found to have commuted into the protected state, deactivating said railway signal, and maintaining said railway signal in the activated state otherwise.

  • Patent number: 10435053
    Abstract: When an event prevents a train from moving along a route in a nominal direction, this method makes it possible to cause it to circulate in an opposite direction by: selecting (120) an origin zone and an output signal; drawing (130) a pseudo-route on the successive zones between the origin zone and the output signal; opening (140) the pseudo-route by associating a sub-route with each zone, corresponding to the reservation of said zone for said train; informing (150) the train that it must circulate in the opposite direction; determining (160) a movement authorization for the train from sub-routes that are open and a list of obstacles that is updated regularly; sending (180) the movement authorization to the train, the determination (160) and transmission (170) steps being iterated until the train crosses the output signal.
