ABSTRACT:
Each train is equipped with an on-board device for detecting the position of the train with respect to the track and with a transmitter-receive communicating with a central station. The central station has an instantaneous storage of the relative positions of all of the trains in the network, storage of the itineraries of each train, the characteristics of the network related to the speed range, and of the performance of the rolling stock in service. The central station constitutes the organizing unit of the system and comprises a transmission at regular time intervals of messages containing the identification numbers of the trains in circulation which are authorized to follow their route, taking account of position information received from these trains by the central station and of speed range parameters contained in the storage. The device on board each train constitutes an execution unit of the system and recognizes the identification number of the train with which it is associated and controls the stopping of the train in the absence of the identification number in the message which it receives from the central station.
