The present invention includes a position detection unit 11; a regenerating-condition detection unit 13 that detects a regenerative-brake usage condition; a train-line-information holding unit 14 that holds therein information on a section in which a train is more likely to use a brake; a residual-air-amount calculation unit 15 that calculates the amount of residual air in an air tank; and a compressor control unit 12 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 12 causes a compressor to start generating compressed air. In a regenerating condition, in which the train uses a regenerative brake, if the amount of residual air is less than 100%, the compressor control unit 12 causes the compressor to generate compressed air. In a normal condition, if the amount of residual air reaches a first threshold value that is greater than 0%, the compressor control unit 12 causes the compressor to start generating compressed air; and if 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 12 causes the compressor to finish generating compressed air. |
