PROBLEM TO BE SOLVED: To provide a door switch inspection device for detecting an abnormal state of a landing door switch used in an elevator.SOLUTION: Each of a plurality of landing door switches is disposed at a landing door corresponding to each landing floor in order to detect an opening/closed state of the landing door. A door switch inspection device comprises: a plurality of voltage detection units, each of which is connected to the grounding side of the corresponding landing door switch in order to detect a voltage value of the corresponding landing door switch; and a switch contact monitoring unit for detecting an abnormal state of each landing door switch. The abnormal state is detected by calculating a voltage difference between two adjacent floors and comparing the voltage difference with a threshold voltage.SELECTED DRAWING: Figure 2

    【課題】 エレベータで使用される乗場ドアスイッチの異常状態を検出するためのドアスイッチ検査装置を提供する。【解決手段】 複数の乗場ドアスイッチのそれぞれが、乗場ドアの開/閉状態を検出するために、各乗場階の対応する乗場ドアに配設される。ドアスイッチ検査装置は、それぞれの乗場ドアスイッチの電圧値を検出するために、それぞれの乗場ドアスイッチの接地側に接続される複数の電圧検出ユニットと、乗場ドアスイッチの異常状態を検出するためのスイッチ接点監視ユニットとを含み、異常状態の検出は、2つの隣接する階の電圧差を計算し、電圧差を閾値電圧と比較することによって実行される。【選択図】図2
