Abstract
A system for controlling a level crossing comprising one or more transceivers located in proximity of a level crossing area on a first side of a railway track; one or more corresponding passive reflective targets located in proximity of the level crossing area on a second side opposite to the first side where each transceiver is located; a control unit connected to each transceiver; wherein each target receives RF signals coming from each transceiver and sends back corresponding reflected signals; each transceiver is arranged to elaborate said reflected signals so as to calculate predetermined parameters values; the control unit acquires said parameters values from each transceiver and elaborates them so as 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.
