The invention discloses a real-time anomaly detection method, device and equipment for an aviation hydraulic pump station and a medium, and relates to the technical field of aviation hydraulic pump station detection. The method comprises the following steps: acquiring historical time sequence data of a target aviation hydraulic pump station; wherein the historical time sequence data is used for representing the performance of the target aviation hydraulic pump station; performing segmentation fitting on the historical time sequence data to obtain segmentation points; based on the segmentation points, classifying the historical time series data after segmentation fitting to obtain a training set; based on the training set, training a constructed initial neural network model to obtain a data prediction model; and detecting the real-time time sequence data of the target aviation hydraulic pump station based on the data prediction model. According to the technical scheme, the fault position of the target aviation
