The embodiment of the invention discloses an elevator fault detection method, device and system and a computer readable storage medium. The method comprises the steps that elevator running state data in the door opening and closing state is obtained; dividing the elevator running state data according to different running stages in a door opening and closing period of the elevator; extracting characteristic values of the elevator running state data corresponding to each running stage; elevator fault diagnosis is conducted according to the characteristic values; and/or when the elevator running state data comprises the vibration data, selecting a running stage with a degradation trend according to the historical vibration data of each running stage, and creating a residual life prediction model according to the historical vibration data of the selected running stage, and predicting the residual life of the elevator operation equipment according to the obtained vibration data and a residual life prediction model. By means of the scheme of the embodiment, elevator fault diagnosis is automatically carried out in time, manpower is saved, and interference of fault coupling is avoided.
本申请实施例公开了电梯故障检测方法、装置、系统和计算机可读存储介质,该方法包括:获取在开关门状态下的电梯运行状态数据;对电梯运行状态数据依据电梯的一个开关门周期内的不同运行阶段进行划分;对每个运行阶段对应的电梯运行状态数据分别进行特征值的提取;根据特征值进行电梯故障诊断;和/或,在电梯运行状态数据包括振动数据时根据每个运行阶段的历史振动数据选出具有退化趋势的运行阶段,根据选出的运行阶段的历史振动数据创建剩余寿命预测模型,并根据获取的振动数据和剩余寿命预测模型预测电梯运行设备的剩余寿命。通过该实施例方案,实现了及时、自动地进行电梯故障诊断,节省人力,并避免故障耦合的干扰。
