The invention discloses a KPI (Key Performance Indicator) anomaly detection method, device and equipment and a medium, which are applied to the technical field of KPI anomaly, and the method comprises the following steps: obtaining one-dimensional KPI time sequence data of a target interval; wherein the length of the target interval is a first preset time length, and the end time point of the target interval is a specified time point; extracting a first data feature of the one-dimensional KPI time sequence data; inputting the first data feature into a base classifier, and outputting a preliminary anomaly detection result of the single-dimensional KPI time sequence data by using the base classifier; extracting a second data feature of the target time point, and inputting the second data feature and the preliminary anomaly detection result into a label classifier to obtain a classification result; wherein the target time point is any time point within a second preset time length after the pointing time point; a
