As shown in FIG. 2, the power consumption of the platform door device 20 increases when the doors 22 are opened and closed, and is highest when the doors 22 are opened and closed. The power consumption at the start of opening and closing the door 22 is defined as "starting power W1", and the power consumption during the opening and closing of the door 22 is defined as "operating power W2"(W1>W2). The power consumption of the platform door device 20 when the doors 22 are not opened or closed is "standby power W0"(W0<W2<W1) because the platform door device 20 is in the standby state.

The platform door device 20 stores power in the storage battery 23 via the platform door distribution board 12 when it is in a standby state with relatively low power consumption. The platform door device 20 can reduce the power consumption associated with charging the storage battery 23 by charging the storage battery 23 so that the power consumption is lower than the operating power W2. When the power consumption in the platform door distribution board 12 approaches the power supply capacity, the platform door distribution board 12 suppresses charging of the storage battery 23 to the platform door device 20 via the platform door control board 11. cause or stop.

Until the train arrives at the platform 2 and stops, the platform door device 20 is in a standby state, and the power consumption is standby power W0.

Subsequently, the doors 22 of the platform door device 20 are opened in synchronization with the opening of the doors of the train. The power consumption of the platform door device 20 is starting power W1 from the start of the opening operation of the door 22 to time TA, and then is operating power W2 from the start of the opening operation to the time TB when the opening operation ends.

Subsequently, while the doors 22 of the platform door device 20 are fully open and passengers are getting on and off, the power consumption of the platform door device 20 is standby power W0.
Subsequently, the doors 22 of the platform door device 20 are closed in accordance with the closing operation of the doors of the train. The power consumption of the platform door device 20 from the start of the opening operation of the door 22 of the platform door device 20 to the time TA is starting power W1. The time TA is, for example, approximately 1 to 2 seconds. The power consumption of the platform door device 20 during the opening operation after the time TA has elapsed is the operating power W2. A time TB from the start of the opening operation to the end of the opening operation is, for example, 3 to 15 seconds.
