Abstract: A RIO device mounted to a train includes an output unit that outputs a signal to a relay mounted to the train, and a controller that controls whether or not to cause the output unit to output the signal. The output unit includes a readback circuit that detects whether or not the signal is outputted from the output unit. The controller makes a signal stop request and a signal output request to the output unit before operation of the train starts, acquires a detection result of the readback circuit while each of the signal stop request and the signal output request is performed, and detects abnormality of the output unit using the detection result.

Abstract: An operation status reproducing device includes an onboard information obtaining unit that obtains onboard information corresponding to date and time from an onboard device mounted on a designated train being a train specified by a train number and the date and time externally designated, a specific event detecting unit that specifies time at which a specific event occurs by analyzing the onboard information, a ground information obtaining unit that obtains ground information in a certain period including the time at which the specific event occurs from a ground device, an external information obtaining unit that obtains external information including weather information in a certain period including the time at which the specific event occurs, and a reproduction image generating unit that generates a reproduction image illustrating a past operation status of the designated train based on the onboard information, the ground information, and the external information.

Abstract: 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.

Abstract: An object is to obtain a ground device capable of reducing a communication time of train information from an onboard device to the ground device. A ground device, which is capable of communicating with an onboard device and acquiring unreceived data from the onboard device by difference downloading or batch downloading, includes a difference-communication determiner to determine whether to acquire the unreceived data from the onboard device by difference downloading or to acquire all data to be acquired from the onboard device including the unreceived data by batch downloading. The difference-communication determiner includes a communication-time evaluator to evaluate a total communication time when data in a specified period is acquired by the batch downloading and that by the difference downloading, and a communication switch to output a download instruction based on a result of evaluation by the communication-time evaluator.

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.
