TRAIN-INFORMATION MANAGEMENT DEVICE AND DEVICE CONTROL METHOD

The present invention includes a position detection unit 11; a regenerating-condition detection unit 13 that detects a condition in which the regenerative-brake is used; 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; an air-conditioning set-value holding unit 15 that holds therein a temperature set value of an air conditioner; and a target-temperature control unit 12 that decides a target temperature that is designated to the air conditioner. 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 12 decides a value, generated by adding a predetermined value to the temperature set value, as the target temperature. In a regenerating condition in which the train uses a regenerative brake, the target-temperature control unit 12 decides a value, generated by subtracting a predetermined value from the temperature set value, as the target temperature. In a normal condition that is neither the regeneration-preparation condition nor the regenerating condition, the target-temperature control unit 12 decides the temperature set value as the target temperature.
