METHOD FOR INITIALIZING THE FS MODE FOR THE MOVEMENT OF A TRAIN ON A RAILWAY EQUIPPED WITH AN ERTMS/ETCS SIGNALING SYSTEM

摘要

This method for initializing the Full Supervision - FS - mode for the movement of a train (4) on a railway (2) equipped with a signaling system (1) complying with the ERTMS/ETCS Level 2 or Level 3 standards, comprises the steps of: - Identifying the signaling block (A6-A3) in which the train was located when an Embedded Vital Computer - EVC - on board the train disconnects from a Radio Bloc Center - RBC - of the signaling system; - monitoring said block by checking periodically that at least one logical constraint that no other train enters in said block is verified, the logical constraint being elaborated from events on the railway in the vicinity of said block; and, when the result of the checking is negative, updating an attribute associated with said block, the attribute switching from the value "FREE" to the value "NOT FREE"; - when the EVC reconnects to the RBC, the RBC reads the attribute and if it has the value "FREE", sends a movement authority to the train to supervise its movement according to the FS mode, at least on said block.
