Ground control device, radio train control system, and radio train control method

摘要

PROBLEM TO BE SOLVED: To provide a ground control device capable of accurately determining a context of two points in a loop-shaped path section.SOLUTION: A ground control device 10 comparing positions between two points in a track with reference to a block number showing a block that is obtained by dividing a track in a loop-shaped path section and a position in the block, comprises a positional information generating unit 11 for generating positional information upon receiving route information of a train 41 and a train 42 in the track and on-rail positional information of the train 41 and the train 42, and a positional relation determination unit 12 for determining a positional relation upon receiving positional information from the positional information generating unit 11 and outputting positional relation information. When a distance between a rearmost vehicle of a preceding train and a leading vehicle of a following train which are two points in a track straddles a connection point which is a starting point and an end point in the loop-shaped path section, the positional relation determination unit 12 adds or subtracts a position correction value corresponding to a traveling direction of the train 41 and the train 42 and determines a positional relation of these two points.SELECTED DRAWING: Figure 1
