TRAIN-INFORMATION MANAGEMENT DEVICE AND DEVICE CONTROL METHOD

摘要

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.

1. A train-information management device that is provided on a train, that manages information on devices provided in a vehicle, and that controls each of the devices, the train-information management device comprising:
a position detection unit that detects a position of the train; a regenerating-condition detection unit that detects whether the train is in a condition of using a regenerative brake; 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 an amount of residual air in an air tank that stores compressed air therein to be used for an air brake; and a compressor control unit that controls a compressor that generates the compressed air on the basis of a detection result obtained by the position detection unit, a detection result obtained by the regenerating-condition detection unit, information held in the train-line-information holding unit, and a calculation result obtained by the residual-air-amount calculation unit, wherein in a regeneration-preparation condition
where a train is running through a position at which a 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 is running toward the section, andwhere a train does not use a regenerative brake when the amount of residual air reaches 0%,the compressor control unit causes the compressor to start generating compressed air,
in a regenerating condition where the train uses a regenerative brake, when the amount of residual air is less than 100%, the compressor control unit causes the compressor to generate compressed air, and in a normal condition that corresponds neither to the regeneration-preparation condition nor to the regenerating condition, when the amount of residual air reaches a first threshold value that is greater than 0%, the compressor control unit causes the compressor to start generating compressed air, and when the amount of residual air reaches a second threshold value that is greater than the first threshold value and less than 100%, the compressor control unit causes the compressor to finish generating compressed air.
