A maker value extraction unit (110) obtains sales profit information of associated equipment of a maker that manufactures the associated equipment. A risk and value calculation unit (105) calculates, based on the sales profit information, a value of the maker manufacturing the associated equipment.

Abstract: A train equipment management system includes an information collection apparatus that collects individual identification numbers for identifying devices from identification tags attached to the devices installed in a train, collects device operation information indicating an operating condition of each device, and transmits, for each device, the individual identification number, the device operation information, a car number for identifying a car in which each device is installed, and a formation number for identifying the train, to a ground system; and the ground system that manages the formation number, the car number, and the device operation information in association with the individual identification number of each device.

Abstract: A vehicle monitoring apparatus (300) transmits transmission data obtained from each appliance (200) and the amount of transmission data to a data processing apparatus (500). First, the data processing apparatus calculates the amount of used resources that is the amount of resources used in processing the transmission data, in the amount of resources of computer resources, on the basis of the amount of transmission data. Next, the data processing apparatus increases or decreases, to the amount of used resources, the amount of secured resources that is the amount of resources secured in the amount of resources of the computer resources. Then, the data processing apparatus processes the transmission data by using the amount of secured resources in the amount of resources of the computer resources.

Abstract: An on-vehicle device mounted on a train includes a second on-vehicle-side wireless communication unit that performs wireless communication with the ground side, and an on-vehicle-side ground-to-vehicle communication security unit that encrypts or decrypts wireless communication data. The on-vehicle-side ground-to-vehicle communication security unit includes an on-vehicle-side secret-key holding unit that retains a plurality of secret keys that have secret key numbers for performing encryption or decryption; an on-vehicle-side secret-key selecting unit that selects one secret key from the on-vehicle-side secret-key holding unit using a secret key number calculated using train information unique to a train; and an on-vehicle-side encryption and decryption processing unit that performs encryption or decryption using the one secret key selected by the on-vehicle-side secret-key selecting unit.

Abstract: An information integration unit (110) generates integrated data (500) based on individual device data (300) and composite device data (400). The individual device data includes, for each individual device, an individual device identifier (311) and an other-device identifier (314) of each of one or more other devices. The composite device data includes, for each set of a composite device, a composite device identifier (421), time period information (424, 425), and an individual device identifier (423) of each of one or more individual devices. The integrated data includes link information (520) for each set of an individual device and one of one or more other devices, and includes link information (530) for each set of a composite device and an individual device. The link information (530) associating the composite device and the individual device with each other includes time period information (522) indicating a time period in which the individual device has been used for the composite device.

Abstract: An object is to enable wireless communication between a portable terminal and on-board devices, and enable wireless connection to a train composition to be subjected to maintenance even in the presence of a plurality of train compositions. A control transmission device is mounted on a train and includes: a port connectable by wire to a maintenance communication device that is an external terminal; a train composition number notification unit that provides notification of a train composition number of the train; and a wireless network ID reception unit that receives a wireless network ID for constructing a wireless network. The wireless network ID received by the wireless network ID reception unit is generated based on the train composition number provided by the train composition number notification unit.

Abstract: A train information management device sends and receives information to and from both a train-controlling in-vehicle wireless station for controlling an operation of a train, and a door-controlling in-vehicle wireless station for controlling vehicle doors. The device includes a wireless train control unit, an automatic operation unit, and a door control unit. The wireless train control unit receives route information represented by a consecutive block sequence and information on a stop limit location that the train may reach without hindering a preceding train, and if this route information includes a station block number, consults an in-vehicle database to extract, before the train arrives at a platform, an arrival track where the train is to stop, a stop target location at a stop station dependent on a travel direction of the train, and which of the vehicle doors is to be opened, and stops the train in accordance with the route information.

Abstract: A train-information management device mounted on a train, includes: an intra-block position calculator to convert information on a kilometrage that indicates a position of the train into information on a block number and an intra-block position of a plurality of blocks into which a route of the train is divided and that are used when a train position is specified by a train radio system; and an on-board router to communicate the information on the block number and the intra-block position to a ground side by using a system that is different from a system that is used for communication between the ground side and a train side via a radio base station in the train radio system.

Abstract: A data management apparatus writes data collected concerning equipment mounted on a railroad vehicle, which is a moving body that repeatedly moves on the same route, during movement of the railroad vehicle into a time-series table. The data management apparatus classifies data stored in the time-series table into a plurality of groups based on a movement location of the railroad vehicle taken when the data was collected. The data management apparatus writes pieces of data classified into the respective groups into a converted table for every group.
