Elevator anomaly detection systems and methods are disclosed. The elevator abnormity detection system is used for precisely detecting the abnormal condition of an elevator and the premonition condition of fault occurrence so as to provide predictive maintenance service. The elevator fault detection device comprises a sensor part for measuring physical parameters of an elevator related to a fault, a data collection part for collecting sensing data measured by the sensor part, and a judgment part for judging whether the sensing data exceeds a preset critical value or not, an interval calculation unit that calculates, as an interval time value, an occurrence time difference between the abnormal modes that occur adjacent to each other for the abnormal modes; and an abnormality score calculator that determines an occurrence density of the abnormal patterns on the basis of an interval time value between the abnormal patterns detected within a predetermined period, and calculates an abnormality score on the basis of the occurrence density.

    公开了电梯异常检测系统和方法。根据本发明的电梯异常检测系统用于精密地检测电梯的异常状况和故障发生的前兆状况以提供预见性维修保养服务,其包括测量与故障相关的电梯的物理参数的传感器部、收集通过传感器部测量的传感数据的数据收集部、对于传感数据判定是否超过预设定临界值,从而检测从正常模式脱离的异常模式的异常模式检测部、对于异常模式将相邻地发生的异常模式之间的发生时间差算出为间隔时间值的间隔算出部、以及以在预定周期内检测到的异常模式之间的间隔时间值为基础来决定异常模式的发生密集程度,并且基于发生密集程度来算出异常分数的异常分数计算器。
