<p><P>PROBLEM TO BE SOLVED: To provide a train control system, an on-board device and a ground device for safely and efficiently controlling a train, even if radiocommunication abnormality is caused. <P>SOLUTION: This train control system communicates between the on-board device 20 mounted on the train and the ground device 10 installed on the ground by radio transmission. The on-board device includes a position detecting means 41, a stoppable position calculating means 43, an on-board telegram transmission means, a ground telegram receiving means, and a train control means. The ground device includes an on-board telegram receiving means, a train existing line information making means 51, a route constituting information making means 52, a stopping limit information making means 53, and a ground telegram transmission means. The train control means of the on-board device controls the train based on a stopping limit position received by the ground telegram receiving means when radiocommunication with the ground device is normal, and stops the train in a range up to a stoppable position capable of confirming that the ground device receives normally by reception confirming information received by the ground telegram receiving means when abnormality is caused in the radiocommunication with the ground device. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
