A terminal device which receives command information from a central device in a train information management system, includes a transmission-reception unit which transmits and receives the command information to and from the central device or other terminal device and periodically receives command information from a plurality of central devices, a control unit which determines whether or not management information, which is information on a train composition set by a central device which is a transmission source, regarding the received command information, is normal command information and determines command information to be adopted based on a priority set to the central device which is the transmission source when receiving the normal command information from the plurality of central devices, and a storage unit which stores information on the priorities set to the plurality of central devices.

Terminal device, central device, train information management system, and train information management method

A plurality of apparatuses mounted on cars are monitored and controlled by control devices mounted on the cars. A display device capable of displaying apparatus information of the apparatuses is mounted on a driver's cab. A display screen of the display device is configured by arranging a plurality of display components by which apparatus information of each of the apparatuses can be displayed. A software generating device determines arrangement positions of the display components arranged on the display screen, automatically generates layout design data of the display screen, and automatically generates software for generating the display screen on the basis of the layout design data. The arrangement positions of the display components respectively representing the apparatuses when a number of apparatuses of the same type are monitored and controlled by one and the same control device are determined according to arrangement rule information that is exceptional rules.

Software generating device

In the train data transmission system for a train including a plurality of cars, a front car of the train includes: a front car control device that is a central control device configured to send and receive data to and from a control device of a train information management device installed in a following car; an on-board instrument configured to send state information to the front car control device, and receive a control command from the front car control device; and a display device configured to request data from the front car control device using a transmission data format, and receive the data from the front car control device in accordance with the transmission data format. An address is assigned only to data of the front car in the transmission data format, and the display device allocates data of the following car in sequence.

Train data transmission system and train data transmission program

A train car-to-car communication device includes: a terminal; an intra-composition transmission line connected to the terminal within the same composition for transmitting information; a composition-to-composition communication relay unit connected to the intra-composition transmission line for receiving first information from the terminal within the composition and transmitting the first information to an adjacent composition, and receiving second information from the adjacent composition and transmitting the second information to the terminal within the composition of interest; and a composition-to-composition transmission line for connecting the composition-to-composition communication relay units of the adjacent compositions and transmitting the information, and the composition-to-composition communication relay unit determines a difference between composition directions of the composition as a transmission source of the received information and the composition to which the composition-to-composition communication relay unit of interest belongs, and rewrites to invert direction-dependent information contained in the received information if the composition directions are different.
