Document Type and Number:
Japanese Patent JP2929391
Kind Code:
B2
Abstract:
PURPOSE:To receive information transmitted from car to ground quickly with a central unit by outputting a poling signal preferentially to a terminal unit corresponding to a grounder on which a train has passed through, at time of this train passing. CONSTITUTION:After a train 1 has passed through a grounder 12A, when it is reached to another grounder 12B, ground information out of a central unit 20 being stored in a repeater 13B is taken into the car side, while car information out of the train 1 is stored in the repeater 13B via the grounder 12B. With the car information received, a train passing signal f1 is transmitted to the side of the central unit 20 from a train passing signal generating part 14B, and a train detecting signal is outputted to a terminal unit position judging part 24 from a passage detecting part 22. This terminal unit position judging part 24 reads terminal unit position information of a memory 23, and thereby it is so judged that a position, where the train 1 this time has passed through, is a terminal unit 11B, outputting it to a poling control part 25, and on the basis of the judged result, a sequence control signal of a poling signal is outputted to a central control part 21.
