To provide an elevator door control device capable of detecting that a person or an object gets caught between the elevator doors accurately.SOLUTION: An elevator door control device comprises a motor drive unit 120 for driving a motor for driving to open and close the elevator door and an overload detection unit 130 for detecting an overload state occurring by that an object got caught between the doors. The overload detection unit 130 includes a door opening force calculation unit 131 for calculating the door opening force applied to the object getting caught between the doors in opening operation of the door, an impulse calculation unit 132 for calculating a total of the door opening force within a predetermined time period and a comparison unit 133 for comparing the total of the door opening force calculated by the impulse calculation unit 132 with a predetermined threshold and for detecting that the door is in an overload state when the total of the door opening force exceeds the threshold. When the overload detection unit 130 detects that the door is in overload state, the motor drive unit 120 controls the motor and stops the door opening operation.SELECTED DRAWING: Figure 3
【課題】エレベータのドアに人や物が挟まれたことを精度よく検出することができるエレベータのドア制御装置を提供する。【解決手段】エレベータのドア制御装置は、エレベータのドアを開閉駆動するモータを駆動するモータ駆動部120と、ドアに物が挟まったことにより発生する過負荷状態を検出する過負荷検出部130と、を備える。過負荷検出部130は、ドアの開動作時にドアに挟まった物にかかる戸開力を計算する戸開力計算部131と、予め設定された時間内における戸開力の合計を計算する力積計算部132と、力積計算部132が計算した戸開力の合計と予め設定した閾値とを比較し、戸開力の合計が閾値を超えた場合、ドアが過負荷状態にあることを検出する比較部133と、を備える。ドアが過負荷状態にあることを過負荷検出部130が検出した場合、モータ駆動部120は、モータを制御してドアの開動作を停止させる。【選択図】図3
