To provide a door abnormality detection system which detects door abnormality accompanied by a car traveling regardless of the type of door abnormality by an external sensor and issues an alarm according to the detection result to an external device.SOLUTION: A door abnormality detection system 200 detects a door abnormality of an elevator 100 with a function of an evasive travel to another floor which makes a car 111 travel to another floor when an elevator door causes a door-opening failure. The door abnormality detection system comprises a detection device 210 installed on a car door 112, and to detect the travelling state of the car 111 and an opening/closing operation of the car door 112 as detection information, an abnormality determination part 223 to determine whether or not a door abnormality occurs based on the detected information and to output an alarm instruction, and an alarm generating part 224 to generate an alarm signal according to the alarm instruction. An abnormality determination part 223 detects the door opening failure based on the detected information and determines that the door abnormality occurs when the door opening failure again occurs repeatedly a predetermined number of times after the evacuating travel to another floor executed.SELECTED DRAWING: Figure 3
【課題】外付けセンサにより、乗りかごの走行を伴うドア異常を、ドア異常の種類によらず検出し、検出結果に応じた発報を外部装置に行う。【解決手段】ドアに戸開不良が発生した場合、乗りかご111を他の階に走行させる他階退避走行の機能を備えたエレベーター100のドア異常を検出するドア異常検出システム200であって、かごドア112に設けられ、乗りかご111の走行状態とかごドア112の開閉動作とを検出情報として検出する検出装置210と、検出情報に基づいて、ドア異常が発生しているか否かを判定し、発報指示を出力する異常判定部223と、発報指示に従って発報信号を生成する発報生成部224と、を備え、異常判定部223は、検出情報に基づいて、戸開不良を検出し、実行される他階退避走行後に再度戸開不良が発生することが予め定めた回数繰り返される場合、ドア異常が発生していると判定する。【選択図】図3
