Abstract: An onboard system includes two control parts. Each of the two control parts has the function of performing a first process for controlling the travel of the transport vehicle. In a period during which a first control part being one control part out of the two control parts is performing the first process, a second control part being other control part out of the two control parts does not perform the first process. In the period during which the first control part is performing the first process, the second control part performs a maintenance process for performing maintenance of the transport vehicle.

Abstract: 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.

Abstract: 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.
