Abstract
A ground device includes a control unit, a storage unit, and a ground transmitting and receiving unit. A ground antenna is connected to the ground transmitting and receiving unit. Train information from an on-board device is received by the ground transmitting and receiving unit via the ground antenna, and is then transmitted to the control unit. Meanwhile, information from the control unit is transmitted to the on-board device via the ground transmitting and receiving unit and the on-board antenna. The control unit accumulates the train information on a train in the storage unit, and also transmits, to the on-board device, command information for a device installed in the train.
