Abstract
We provide technology that uses data obtained from existing platform door equipment to accurately grasp the status of platform door devices. [Solution] The platform door device of the present invention comprises a door provided on the platform, a control unit that transmits a close command signal or an open command signal to open or close the door, a drive unit that drives the door to close or open in response to receiving the close command signal or the open command signal, a fully closed position detection unit that outputs a fully closed signal when it detects that the door is in the fully closed position, a fully open position detection unit that outputs a fully open signal when it detects that the door is in the fully open position, a position acquisition unit 32 that acquires a first position of the door when the fully open position detection unit switches between a state in which it outputs a fully open signal and a state in which it does not output a fully open signal, and a second position of the door when the fully closed position detection unit switches between a state in which it outputs a fully closed signal and a state in which it does not output a fully closed signal, and an output unit 36 that outputs the first position and the second position.
