According to an example embodiment, there is provided a device (220) for monitoring operation of a locking mechanism (141, 145), the locking mechanism (141, 145) being applied to secure an elevator door (111, 131) to a closed position, where the monitoring is performed by monitoring operation of a door drive system (230) arranged to drive movement of the elevator door (111, 131) between the closed position and an open position, where the door drive system (230) is arranged to drive movement of the elevator door (111, 131) between the closed position and the open position. The device is arranged to: receive one or more parameters describing movement of the elevator door (111, 131) from the closed position towards the open position; determining a door movement curve based on the one or more parameters, the door movement curve describing an aspect of movement of the elevator door (111, 131) relative to the closed position of the elevator door (111, 131); and detecting compromised operation of the locking mechanism (141, 145) based on one or more characteristics of the door movement curve within a portion representing a predetermined travel distance relative to the closed position of the elevator door (111, 131).
根据示例实施例,提供了用于监控锁定机构(141、145)的操作的装置(220),锁定机构(141、145)应用于将电梯门(111、131)固定到关闭位置,其中监控通过监控门驱动系统(230)的操作来执行,门驱动系统(230)被布置用于驱动电梯门(111、131)在关闭位置和打开位置之间的移动,所述装置被布置成:接收描述电梯门(111、131)从关闭位置朝向打开位置的移动的一个或多个参数;基于一个或多个参数确定门移动曲线,门移动曲线描述电梯门(111、131)相对于电梯门(111、131)的关闭位置的移动的方面;以及基于门移动曲线的在表示相对于电梯门(111、131)的关闭位置的预定行进距离的部分内的一个或多个特性来检测锁定机构(141、145)的受损操作。
