Training AI models using this dataset enables precise recognition of common pressure sensor failure types including drift, jamming, and abnormal noise, and can be applied to scenarios such as underwater equipment condition monitoring, marine observation system maintenance, and hydrological measurement data quality control. Furthermore, this dataset can provide decision-making basis for intelligent equipment health management, predictive maintenance and other applications, improving the reliability of marine observation data. 1. Data Collection Hydrological monitoring data is collected using the enterprise's proprietary ADCP equipment, with synchronized records of data ID, collection time, equipment model, geographic coordinates, original pressure values, water temperature and other related data. 2. Data Preprocessing and Processing Outliers are removed through data cleaning, and the dataset is split at a ratio of 7:2:1. Based on the pressure data, statistical features such as pressure change rate and standard deviation are calculated. A multi-level annotation system is established: - Level 1 label: Normal Pressure / Abnormal Pressure (determined based on the physical threshold of pressure values) - Level 2 label: Drift failure (sustained unidirectional change) / Jamming failure (constant numerical value) / Noise failure (abnormal fluctuation) 3. Model Selection and Initialization A hybrid model combining 1D-CNN and temporal attention mechanism is adopted. The model parameters are initialized and hyperparameters are optimized: dynamically adjusted learning rate within 0.001-0.0001, dynamically adjusted batch size within 32-64, dynamically adjusted time step within 12-32; a physical constraint module is integrated. 4. Model Training Training is implemented using PyTorch, with mixed-precision training (FP16) adopted to improve efficiency. The training duration is set, and data augmentation is performed to simulate different fault modes, including adding effects such as bubble interference, signal interference, and sensor aging. An early stopping mechanism (patience=15) and gradient clipping (max_norm=1.0) are configured. 5. Model Evaluation During the model training process, the validation set is used to adjust hyperparameters. After training is completed, the model performance is evaluated on the test set. The evaluation metrics include: - Basic performance metrics: Accuracy, False Positive Rate - Scenario robustness test: Bubble interference detection rate - Progressive testing: Single fault → Compound fault, Static environment → Dynamic environment
