MOVEMENT AUTHORITY CALCULATING METHOD BASED ON TRAIN CONTROL SYSTEM

摘要

A movement authority calculating method based on a train control system comprises the following steps: reading route information of a train, and determining a traversal range of the train according to the route information(A1); initializing an end point of a movement authority as an end point position of the traversal range (A2); searching for static obstacles in the traversal range, and judging whether each of the static obstacles meets the requirements on safe operation of the train in turn; if not, setting the position of the last static obstacle in the traversal range as the end point of the movement authority; if yes, changing the end point of the movement authority into a matched route end point (A3); searching for dynamic obstacles in the traversal range and judging whether a tracking train exists; if yes, modifying the end point of the movement authority into an initial terminal of an axle counter block in which the train is positioned; and if no dynamic obstacle exists in the traversal range, modifying the final end point of the movement authority into the position of the last static obstacle in the traversal range(A4). The present invention improves the operation efficiency of the train.
