TRAIN INFORMATION MANAGEMENT DEVICE AND TRAIN INFORMATION MANAGEMENT METHOD

摘要

A train information management apparatus includes a first system central device 11-1 configured to generate, based on control input information, first train control information for a car-mounted device in every predetermined period and a second system central device 11-2 configured to generate second train control information, which is the train control information same as or different from the first train control information, based on the control input information starting from time when time obtained by multiplying the predetermined period with 1/2 elapses from a point when the first train control information is transmitted. The first system central device 11-1 generates a first packet every time the first train control information is generated and alternately transmits, every time the first packet is generated, the first packet to a first system trunk transmission line 40-1 and a second system trunk transmission line 40-2. The second system central device 11-2 generates a second packet every time the second train control information is generated and transmits, every time the second packet is generated, the second packet to a trunk transmission line on the opposite side of the trunk transmission line to which the first packet is transmitted.
