  • Patent number: 10586962
    Abstract: An on-board device is mounted on a train having a battery capable of supplying power when a vehicle power supply is off, a parking brake to fix a wheel when the train is stopped, and a parking-brake controlling electromagnetic valve to be energized by power supplied from the battery when the parking brake is released, and even when the vehicle power supply is off, retains position information of the train stored when the vehicle power supply is on. The on-board device includes a parking-brake release detecting circuit that has a parking-brake-controlling-electromagnetic-valve energization detecting unit to detect energization to the parking-brake controlling electromagnetic valve when the vehicle power supply is off, and a parking-brake-controlling-electromagnetic-valve energization detection storage unit to store therein a result of detection until stored contents are reset.

  • Patent number: 10202134
    Abstract: 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.

  • Patent number: 9393976
    Abstract: After latest door opening-side information is received from an operational management server on a ground after a train starts an operation, train-information managing apparatuses output the door opening-side information to display control apparatuses as guidance data, the display control apparatuses create video data indicating an opening side of doors for all stops at least between a next stop and a terminal station of the train using the door opening-side information, and displays perform display using the video data.

  • Patent number: 9387774
    Abstract: The train-information management device includes a position detection unit; a regenerating-condition detection unit that detects a regenerative-brake usage condition; a train-line-information holding unit that holds therein information on a section in which a train is more likely to use a brake; a residual-air-amount calculation unit that calculates the amount of residual air in an air tank; and a compressor control unit that controls a compressor. In a regeneration-preparation condition, if a train is running through a position where the distance between the position and a section in which a train is more likely to use a brake is equal to or less than a given value, if the train does not use a regenerative brake, and if the amount of residual air reaches 0%, the compressor control unit causes a compressor to start generating compressed air.

  • Patent number: 9254753
    Abstract: The present invention includes a position detection unit; a regenerating-condition detection unit; a train-line information holding unit that holds therein information on a section in which a train is more likely to use a brake; an air-conditioning set-value holding unit that holds therein a temperature set value of an air conditioner; and a target-temperature control unit that decides a target temperature. In a regeneration-preparation condition in which a train is running through a position at which the distance between the position and a section in which a train is more likely to use a brake is equal to or less than a given value and in which the train does not use a regenerative brake, the target-temperature control unit decides a value, generated by adding a predetermined value to the temperature set value, as the target temperature.

  • Publication number: 20140336851
    Abstract: Train information managing apparatuses each include a plurality of pieces of control software of versions different from each other. The train information managing apparatus mounted on a head car compares version information of software for devices collected concerning all devices in a formation and version correspondence information included in each of the plurality of pieces of control software, discriminates control software including version correspondence information consistent with the version information of the software for devices concerning all the devices in the formation, when the discriminated control software is different from already-started control software, selects and starts the discriminated control software, and transmits a switching command for switching from the already-started control software to the discriminated control software to a train information managing apparatus mounted on another car.
