Platform door anomaly detection method and device, terminal equipment and storage medium

The embodiment of the invention discloses a platform door anomaly detection method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining the motion data of different equipment when a platform door executes a door opening motion, the action data of the different devices comprises door body speed data of the platform door, current data of a motor, amplitude data of a belt and current data of an electromagnetic lock; according to the action data of the different devices, action curves of the different devices when the door opening action is executed are constructed; dividing each action curve to obtain a segmented curve of each action curve; extracting a feature value from the segmented curve, and performing dimension reduction on the feature value to obtain a dimension-reduced feature value; and inputting the dimensionality reduction characteristic value into a preset anomaly detection model to obtain an anomaly detection result of the platform door. According to the
