| Summary: | The stacker is an important part of automatic storage. The safety and health of the running track are the primary premise to ensure the stable operation of the stacker. In this paper, a new combinational method to locate abnormal interval for running track of stacker is proposed. First, the interval smoothing method and data interpolation method are used for preprocessing of the original current data sampled from stackers; second, the box plot method for outlier detection is applied to the smoothed data; at the same time, in order to make up for the defect of the box plot method that can only detect the extreme points, failing to detect abrupt change points, the box plot method is combined with the wavelet transformation method to construct a combinational anomaly interval location method; finally, the validity of the algorithm proposed in this paper is verified by the running current data of the stacker in the intelligent operation and maintenance warehouse of the national power grid.
