To provide an elevator door control device and a door diagnosis method capable of specifying a detailed occurrence factor when an abnormality occurs in an elevator door.SOLUTION: An elevator door control device according to an embodiment is connected to a door motor that is equipped with a pulse generator, a door full-open detection switch that outputs a door full-open detection signal when the elevator door is fully open, and a door full-close detection switch that outputs a door full-close detection signal when the elevator door is fully closed, and comprises a torque value calculation unit, a pulse value measurement unit, a switch signal acquisition unit, and a diagnosis unit. The torque value calculation unit calculates a torque value applied to the door motor from a current value flowing through the door motor. The pulse value measurement unit measures a pulse value generated from the pulse generator. The switch signal acquisition unit acquires a door full-open detection signal and a door full-close detection signal. The diagnosis unit performs door diagnosis processing on the basis of the calculated torque value, the measured pulse value, and the obtained signal to determine whether there is an abnormality.SELECTED DRAWING: Figure 1

    【課題】 エレベータのドアで異常が発生した際に、詳細な発生要因を特定することが可能な、エレベータのドア制御装置およびドア診断方法を提供する。【解決手段】 実施形態によればエレベータのドア制御装置は、パルス発生器が設けられたドアモータと、エレベータドア全開時にドア全開検知信号を出力するドア全開検知スイッチと、エレベータドア全閉時にドア全閉検知信号を出力するドア全閉検知スイッチとに接続され、トルク値演算部とパルス値計測部とスイッチ信号取得部と診断部とを備える。トルク値演算部は、ドアモータに流れる電流値からドアモータにかかるトルク値を演算する。パルス値計測部はパルス発生器から発生したパルス値を計測する。スイッチ信号取得部はドア全開検知信号およびドア全閉検知信号を取得する。診断部は、演算されたトルク値、計測されたパルス値、および取得された信号に基づいてドア診断処理を行い、異常の有無を判定する。【選択図】図1
