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 communication device operating as a hub in a train network system that includes a plurality of hubs installed in train vehicles, each of the plurality of hubs belonging to both a trunk network in which a signal transmission range is not limited and a branch network in which a signal transmission range is limited, and adding, to a signal to be transmitted to a hub belonging to the same branch network as it does, network type information indicating whether the signal is a trunk network signal or a branch network signal. The communication device transmitting branch network information including at least identification information on a branch network to which it belongs at a predetermined timing, and based on branch network information received from an adjacent communication device, determining whether or not to add the network type information to a signal to be transmitted to the adjacent communication device.

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.

摘要: A communication apparatus is mounted on a train and forms a train communication system together with a system control apparatus that generates control frames including general and low-latency frames. The communication apparatus includes: a general transfer processing unit that stores the general frame; a low latency transfer processing unit that stores the low-latency frame, the low latency frame requiring transferring with lower latency than the general frame; a frame identification unit that identifies priority of the control frame and outputs the control frame to the general transfer processing unit or the low latency transfer processing unit based on a priority setting table indicating the priority of the control frame and set in the identification unit; an output control unit that preferentially transfers the low-latency frame over the general frame; and a control unit that modifies the priority setting table.
