Elevator abnormal vibration detection method based on residual analysis

The invention relates to an elevator abnormal vibration detection method based on residual analysis. The method comprises the following steps of a, collecting acceleration data of elevator operation,carrying out the residual decomposition, and calculating the peak-to-peak value of a decomposed residual sequence; b, detecting an abnormal value in the peak-to-peak value, and enabling the abnormal value to form a vibration section in a corresponding abnormal section in the residual sequence in a merging manner; and c, analyzing the vibration attribute of the vibration section, carrying out stagedivision on the acceleration, and determining the vibration generation stage. According to the method, more vibration related data, including the vibration duration, the vibration intensity and the vibration generation stage can be acquired. 本发明涉及一种基于残差分析的电梯异常振动检测方法，包括以下步骤：a、采集电梯运行的加速度数据并进行残差分解，计算分解后的残差序列的峰峰值；b、检测峰峰值中的异常值，并以合并的方式使异常值在残差序列中对应的异常段形成振动段；c、分析振动段的振动属性，并对加速度进行阶段划分，确定振动发生阶段。本发明的方法能够获取到更多的振动相关数据，包括振动时长、振动强度和振动发生阶
