The invention provides an elevator pulley bearing anomaly detection method and device, and belongs to the technical field of elevators. According to whether the number of times that the collected noise is greater than a preset noise threshold value in a preset time period reaches a preset number of times, the continuity of the situation that the collected noise is greater than the preset noise threshold value in the preset time period and whether the situation that the noise is greater than the preset noise threshold value exists in a previous first preset time period, the noise is acquired; whether the pulley bearing is abnormal or not is judged, whether the pulley bearing is abnormal or not can be judged in real time, an alarm is given to elevator management personnel or maintenance personnel, and the safety of an elevator is guaranteed.

    本发明提供了一种电梯滑轮轴承异常检测方法及装置,属于电梯技术领域。根据采集的噪音在预设时间段内大于预设的噪音阈值的次数是否达到预设次数、采集的噪音在预设时间段内噪音大于预设的噪音阈值的情况发生的连续性以及上一第一预设时间段内是否存在噪音大于预设的噪音阈值的情况,判定滑轮轴承是否存在异常,能够实时判定滑轮轴承是否存在异常,并向电梯管理人员或维保人员报警,保证电梯的安全性。
