To provide a technique that can diagnose abnormalities of a switch for sensing fully-closed state of a door and of a position of a member for pressing a movable contact of the switch more properly.SOLUTION: A door control device 100 according to one embodiment obtains time-series data on output from a DCS 60 that senses a position of a door 80 in a period of time during which the door 80 of a railway vehicle 1 is in closing motion or in a period of time during which the door is in opening motion and a fully-closes state of the door 80; and diagnoses an abnormality of a position of at least either of the DCS 60 and a DCS contact part 213 for pressing a movable contact 62 of the DCS 60, on the basis of the obtained data.SELECTED DRAWING: Figure 11
【課題】ドアの全閉状態を検知するスイッチやスイッチの可動接点を押圧するための部材の位置に関する異常の診断をより適切に行うことが可能な技術を提供する。【解決手段】一実施形態に係るドア制御装置100は、鉄道車両1のドア80の閉動作の期間又は開動作の期間でのドア80の位置、及びドア80の全閉状態を検知するDCS60の出力の時系列のデータを取得し、取得したデータに基づき、DCS60、及びDCS60の可動接点62を押圧するためのDCS当接部213の少なくとも一方の位置に関する異常の診断を行う。【選択図】図11
