Abstract
Provided is a station device configured to detect a first zero crossing point (ZCP) and a second ZCP with respect to an alternating current (AC) input voltage, by using a ZCP circuit configured to detect a ZCP of the AC input voltage applied to the station device, obtain information about a pulse width from the first ZCP to the second ZCP, identify whether the AC input voltage is in an overvoltage state, based on the information about the pulse width from the first ZCP to the second ZCP, and deactivate an operation of the suction motor, when the AC input voltage is in the overvoltage state. Where detecting the first ZCP and the second ZCP includes detecting voltage points which are offset from 0 V by a preset value in the AC input voltage.
