    摘要: An object is to provide an in-train transmission control system which can minimize delay in transmission of command data to devices further than the conventional art, in which a central unit provided in any car of a train formation composed of one or more cars and controlling operation of the entire train formation transmits command data to devices provided in some or all of the cars and in which the devices transmit device data to the central unit. The control system comprises relay device provided in the car, and line concentrator allowing the command data to pass therethrough, and when receiving device data from the devices, transmitting the device data to the relay device. The relay device aggregates the device data received from the line concentrator to transmit the aggregated data to the central unit.

    摘要: A train information managing apparatus according to the present invention includes: a terminal apparatus that communicates with a train-mounted device; and a central apparatus that communicates with the terminal apparatus and the train-mounted device. In at least one of the terminal apparatus and the central apparatus, a processing system that includes a signal processing unit is duplicated, the signal processing unit generating a command signal for the train-mounted device and receiving a response signal made in response to the command signal, and at least one of the signal processing units that receive a response signal from the train-mounted device transmits, to another of the signal processing units, information indicating receipt of the response signal so as to be used to determine a failure in one of the processing systems.
