Patent number: 9515944Abstract: 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.Type: GrantFiled: December 12, 2011Date of Patent: December 6, 2016Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Shogo Tatsumi, Takashi Miyauchi, Toshiko Kadono, Tetsuo Komura, Shingo Honda, Takuya Sawa

Patent number: 9387774Abstract: 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.Type: GrantFiled: August 14, 2012Date of Patent: July 12, 2016Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Takuya Sawa, Tomoaki Ikejima, Tetsuo Komura, Shogo Tatsumi, Shingo Honda, Toshiko Kadono, Takashi Miyauchi
