PROBLEM TO BE SOLVED: To solve the problem in which failure of a link mechanism cannot be prevented in advance because an abnormality due to long-term deterioration of a link type door cannot be detected.SOLUTION: An elevator control device 20 comprises a car door switch operation position calculation unit 22 and a car door switch operation position abnormality determination unit 26. The car door switch operation position calculation unit 22 calculates an operation position of a car door switch 8 that detects an opened/closed state of a link type door 7 opened and closed by a link mechanism, as a measured value of the car door switch 8. The car door switch operation position abnormality determination unit 26 determines that an abnormality has occurred in the link type door 7 when the measured value of the car door switch 8 is out of the range of a specified value.SELECTED DRAWING: Figure 1

    【課題】リンク式ドアの経年劣化による異常を捉えられないため、リンク機構の故障を未然に防止することができない。【解決手段】エレベーター制御装置20は、かごドアスイッチ動作位置計算部22と、かごドアスイッチ動作位置異常判定部26と、を備える。かごドアスイッチ動作位置計算部22は、リンク機構により開閉するリンク式ドア7の開閉状態を検出するかごドアスイッチ8の動作位置を、かごドアスイッチ8の計測値として計算する。かごドアスイッチ動作位置異常判定部26は、かごドアスイッチ8の計測値が規定値の範囲外であるときに、リンク式ドア7に異常が生じたと判定する。【選択図】図1
