This invention relates to the field of aquaculture technology, specifically to a deep learning-based aquaculture heat pump fault prediction and adaptive temperature control system and method. The system includes data acquisition, feature extraction, intelligent analysis, decision control, and execution interaction modules. The data acquisition module collects temperature, pressure, flow rate, and power parameters of the heat pump system. The feature extraction module extracts time-domain, frequency-domain, time-frequency, and thermodynamic features from these parameters. The intelligent analysis module includes a fault prediction submodule, an energy efficiency optimization submodule, and a temperature control strategy submodule, used to predict faults and energy efficiency indicators, and generate a dynamic temperature difference setpoint. The decision control module generates a control strategy based on the fault prediction results and the temperature difference setpoint. The execution interaction module receives the control strategy and controls the heat pump system. This system improves water temperature control accuracy to ±0.5℃, far superior to the ±2.1℃ of traditional systems, meeting the aquaculture needs of high-value aquatic species.
