GROUND DEVICE FOR WIRELESS TRAIN CONTROL SYSTEM AND WIRELESS TRAIN CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To enable reliable and secure detection of existence of a train on a track, in a train control system in which an on-vehicle device transmits positional information of the train itself to a ground device via wireless communication.;SOLUTION: In a wireless train control system, a ground device 30 detects existence on a track with a positional detection section S defined as a unit on the basis of an on-vehicle positional signal received from an on-vehicle device. In a closed logic circuit part 200 disposed in the ground device 30, an immediate past result of detecting existence on a track is continuously retained by means of a position storage relay, and non-existence on a track in a detection-target positional detection section S is quickly detected by a track relay 1TR in a track circuit detection section including the detection-target positional detection section S, even when the on-vehicle positional signal from the on-vehicle device is no longer received.;COPYRIGHT: (C)2014,JPO&INPIT
