    Abstract: It makes it possible to track instrument information and to obtain an accurate history of the instrument information, even when a mounting position mounted with a railway vehicle instrument has been changed. Instrument information indicating an operation or a state of a railway vehicle instrument mounted to each mounting position included in a composition is collected. A serial number determined for each mounting position is updated. The instrument information is assigned with a temporary ID including position information specifying the each mounting position and a serial number. A combination of a new temporary ID and an old temporary ID included in the temporary ID group and assigned to new instrument information and old instrument information indicating an operation or a state of a same railway vehicle instrument is estimated.

  • Patent number: 9553931
    Abstract: A train-information managing apparatus receives a series of control information attached to serial numbers, which are transmitted from a central apparatus, in order of the transmission and carries out control in the order, and even when the central apparatus is changed or the serial numbers are reset, prevents a blank period of control from occurring. Therefore, when a reception serial number n included in received data is a preferential serial number (n?M) and an old number nprev, which is a serial number included in data received and stored last time, is a cyclic serial number (nprev?M+1), the train-information managing apparatus stores the received data.

  • Patent number: 9515944
    Abstract: A train information management apparatus includes a first system central device that generates first train control information for a car-mounted device in every predetermined period and a second system central device that generates second train control information starting from the time at which the time obtained by multiplying the predetermined period with 1/2 has elapsed from the time point when the first train control information is transmitted. The first system central device generates a first packet every time the first train control information is generated and alternately transmits a first packet to a first system trunk transmission line and a second system trunk transmission line. The second system central device generates and transmits a second packet almost in the same manner except that the second packet is transmitted to a trunk transmission line on the opposite side of the trunk transmission line to which the first packet was transmitted.

  • 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.
