TRAIN-INFORMATION MANAGEMENT DEVICE AND TRAIN-INFORMATION MANAGEMENT METHOD

摘要

A central device includes an information replacing unit. When the information replacing unit detects, on the basis of contact information acquired from an electric coupler provided in a coupled vehicle in a formation B having a train-information management device that manages vehicle information in accordance with the Ethernet® protocol, that a formation A that includes a train-information management device that manages vehicle information in accordance with the ARCNET protocol is coupled to the formation B, then the information replacing unit replaces vehicle information from the formation A with vehicle information in accordance with the Ethernet® protocol; outputs the replaced vehicle information to the formation B; replaces the vehicle information from the formation B with the vehicle information in accordance with the ARCNET protocol; and outputs the replaced vehicle information to the formation A.

主权项

1. A train-information management device comprising a central device that is connected to the Ethernet® provided over a plurality of vehicles constituting a train formation and that manages vehicle information in accordance with the Ethernet® protocol, wherein
the central device comprises an information replacing unit that, when having detected that a second formation including a train-information management device that manages vehicle information in accordance with an ARCNET protocol is coupled to a coupled vehicle in a first formation having the train-information management device,
replaces vehicle information from the first formation with vehicle information in accordance with the ARCNET protocol and outputs the replaced vehicle information to the second formation, andreplaces the vehicle information from the second formation with the vehicle information in accordance with the Ethernet® protocol and outputs the replaced vehicle information to the first formation, and an information transmitting unit that, when having detected that a third formation of a same type as the first formation is coupled to the first formation,
outputs vehicle information from the third formation to the first formation, andoutputs the vehicle information from the first formation to the third formation.
