The invention provides an elevator door monitoring device and an elevator door monitoring system, which can realize control with high convenience according to the motion state of a door even if a signal from a door safety device carried in an elevator cannot be obtained. The elevator door monitoring device is connected with a maintainer terminal carried by a maintainer of an elevator through a communication line and monitors a door of the elevator, and in the elevator door monitoring device, a current detector is arranged in a motor enabling a car door to be opened and closed. When the numberof times the current detected by the current detector exceeds a threshold value reaches a predetermined condition, information for prompting the change of the operation of the car door is transmittedto the maintainer terminal.
本发明提供一种电梯门监视装置以及电梯门监视系统,即使在无法得到来自在电梯中搭载的门安全装置的信号的情况下,也能够根据门的动作状况来实现便利性高的控制。电梯门监视装置经由通信线路与电梯的维护作业员所携带的维护员终端连接,并监视上述电梯的门,在该电梯门监视装置中,在使轿厢门开闭的电动机中设置电流检测器,在通过上述电流检测器检测出的电流超过阈值的次数成为预定条件时,向上述维护员终端发送促使变更上述轿厢门的动作的信息。
