Title: WIRELESS TRAIN CONTROL SYSTEM, ABOVE-GROUND CONTROL DEVICE, AND WIRELESS TRAIN CONTROL METHOD
Abstract:
In order to procure a wireless train control method that can be stably put into practice, provided are: a track circuit status information acquisition device for generating a track circuit status signal TR that indicates whether a track circuit of a track is raised or lowered, and a time-element-incorporating track circuit status signal TR-X that indicates the track circuit is lowered at a timing delayed by a set time after the track circuit status signal has indicated that the track circuit is lowered; and an above-ground control device for generating a stopping limit point for a wireless-control-supporting train 41 by using current railway information when the train preceding the wireless-control-supporting train 41 is a wireless-control-supporting train 43, and generating a stopping limit point for the wireless-control-supporting trains 41, 43 by using the track circuit status signal TR and the time-element-incorporating track circuit status signal TR-X when the train preceding the wireless-control-supporting train 41 is a wireless-control-non-supporting train 42. The above-ground control device does not update the stopping limit points when the track circuit status signal TR indicates that the track circuit is lowered and the time-element-incorporating track circuit status signal TR-X indicates that the track circuit is raised.
