Train control device

摘要

A train control device includes an on-vehicle base station mounted on a train, base stations that can communicate with the on-vehicle base station, an on-vehicle control device controlling an operation such that the train can stop before reaching a stop limit before which the train can run safely, and ground control devices that transmit, to the train side, the stop limit calculated based on information on the current position acquired from the train side via the base stations and opening information on a turnout on the ground. The on-vehicle control device calculates a channel-reservation start pattern, which is a pattern determining a reservation start position of a communication channel of a base station as a switching target when the base station as a communication partner to the on-vehicle base station is switched and in which the reservation start position is different according to train speed and train position.

主权项

1. A train control apparatus comprising:
an on-vehicle base station that is mounted on a train; a ground base station that is installed on a ground and is capable of communicating with the on-vehicle base station; an on-vehicle control device that is mounted on the train, reports a current position of the train to the ground base station via the on-vehicle base station, and controls an operation such that the train is capable of being stopped before reaching a stop limit, which the on-vehicle control device has acquired from the ground base station via the on-vehicle base station and which is a limiting position before which the train is capable of running safely; and a ground control device that is installed on the ground and transmits the stop limit, which is calculated on a basis of information on the current position acquired from the on-vehicle control device via the on-vehicle base station and the ground base station, to the on-vehicle control device via the on-vehicle base station and the ground base station, wherein the on-vehicle control device, when the ground base station that is a communication partner to the on-vehicle base station is switched, includes
a channel-releasing-pattern calculation unit that calculates a channel releasing pattern that determines a position where a communication channel of the ground base station that is a switching source is released after performing switching of the ground base station that is a communication partner to the on-vehicle base station on a basis of a train speed and a train position, anda communication-channel releasing unit that, when detecting that the train has passed the channel releasing pattern, releases the communication channel of the ground base station that is a switching source.
