Train control system, base-station control device, ground wireless base station, and on-vehicle wireless station
First Claim
1. A train control system for controlling an operation of a train by transmitting and receiving, between an on-vehicle wireless station mounted on the train and a ground wireless base station, information that includes train control information by wireless communication, the train control information being information for controlling an operation of the train, whereinthe information that includes the train control information further includes general transmission information that is information other than the train control information,the ground wireless base station includes a first processor to execute a first program and a first memory to store the first program which, when executed by the first processor, performs processes oftransmitting the general transmission information only once from the ground wireless base station to the on-vehicle wireless station,transmitting the train control information repeatedly a plurality of times from the ground wireless base station to the on-vehicle wireless station, andamong the repeatedly transmitted train control information, the on-vehicle wireless station uses, for an operation of the train, a piece of train control information, which the on-vehicle wireless station receives without lack of data for a first time.

Abstract
A train control system controls an operation of a train by transmitting and receiving, between an on-vehicle wireless station mounted on the train and a ground wireless base station, information that includes train control information by wireless communication. General transmission information, which is information included in the information that includes the train control information and is transmitted only once from the ground wireless base station to the on-vehicle wireless station. The train control information is transmitted repeatedly a plurality of times from the ground wireless base station to the on-vehicle wireless station. Among the repeatedly transmitted train control information, the on-vehicle wireless station uses, for an operation of the train, a piece of train control information, which the on-vehicle wireless station receives without lack of data lack for a first time.
