System for occupancy detection in a railroad line and for digital communication with trains that run along said railroad line

摘要

A system for occupancy detection in a railroad line, or the like, and for digital communication with trains running along the railway line, in which, a) the track which forms the railroad line is divided into a plurality of segments of successive via galvanically isolated having a predetermined length, called blocks, the rails of each track segment isolated forming a track circuit (cBD, cdB1, cdB2, cdB3) for detecting the presence of a train within said isolated track segment, for communicating with a train within said insulated track segment and / or for detecting diagnostic data about the state of the said isolated track segment; b) it is provided a central unit (1) control and supervisory generates and transmits control signals to execute procedures train detection and / or procedures for communication with the train relative to a train traveling on that segmentode isolated path and / or to execute diagnostic procedures; c) a central unit (1) control and monitoring communicates with the track circuit (cBD, cdB1, cdB2, cdB3) of each track segment isolated by a subunit (2, 2 ', 2 ") control and monitoring, associated with each segment isolated track or track circuits (cBD, cdB1, cdB2, cdB3) to generate and receive codes, and which subunit (2, 2 '', 2¿¿) control and supervisory procedures executed to detect the presence of a train (T) within the track segment associated isolated.
