Patent ID: 7756613

Claim:
A signaling system for ensuring protection of a train traveling within a predetermined section by only one signaling telegram; said system being configured such that said one signaling telegram patrols trains which are within said predetermined section and points located within said predetermined section, and contains lock position instruction information for the points and block occupancy information that assigns the right of occupied in one area by a train to each of blocks formed in multiple numbers by division of said predetermined section and point position status information; the block occupancy information which is included in said only one signaling telegram is configured to be updated only in the train in which said only one signaling telegram is patrolling, the point position status information which is included in said only one signaling telegram being able to be updated only in the point in which said only one signaling telegram is patrolling; the signaling system configured to be operatively associated with the train so that when the train is going to enter the next block, the train checks said only one signaling telegram having been received for the information on the right of block occupancy, and the train cannot enter the next block if another train holds the right of block occupancy; a train configured to identify the state of occupancy of the block to be entered by checking the information on the right of occupancy of the block to be entered described in the received only one signaling telegram, and, if another train has not yet secured the right of block occupancy, the identification data of the former train is added to the information on the right of occupancy of the block corresponding to the one to be entered, whereby the right of block occupancy is ensured; and when said train has departed the block, the train is configured to erase the identification data thereof from the information on the right of occupancy of the block corresponding to the one from which the train has departed upon receipt of said only one signaling telegram; and the signaling system configured to be operatively associated with the point so that when the point switches over the lock position, the point describes current position in the point lock position information of said only one signaling telegram; thereby exclusively controlling the right of block occupancy and the lock position status for the points in the one area by said only one signaling telegram.
