TRAIN-ENERGY CONTROL SYSTEM, GROUND DEVICE, AND ON-BOARD DEVICE

摘要

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.

主权项

1. A ground device comprising:
a ground transmitting and receiving unit that receives, from each of a plurality of trains running within a same feeding section, running-state information that indicates a running state, which is any of a regenerative braking state, an accelerating state, and a coasting state, and storage-battery-state information that indicates a state of charge of a storage battery provided in the train; and a control unit that determines whether there is a train that has the running-state information indicating a regenerative braking state on a basis of the running-state information on the trains received by the ground transmitting and receiving unit, and, when the running-state information on one or more of the trains indicates a regenerative braking state, determines a train that absorbs regenerative power from among the trains on a basis of the running-state information and storage-battery-state information on the trains, and controls the ground transmitting and receiving unit such that a power absorption command is transmitted to the determined train.
