This dataset is primarily designed to enhance the recognition capability and accuracy of AI models for identifying the life decay status of ADCP (Acoustic Doppler Current Profiler) equipment. Training on this dataset enables AI models to accurately identify performance degradation phenomena, and can be applied to scenarios such as preventive maintenance of hydrological measurement equipment, optimization of instrument replacement cycles, and assessment of the reliability of measurement data quality. Additionally, this dataset can provide scientific evidence for equipment full-life cycle management, intelligent maintenance decision-making, etc., improving the operational reliability of hydrological observation systems.

1. Data Collection
Monitoring data is collected using the enterprise's own ADCP equipment, with simultaneous recording of data ID, collection time, equipment model, geographic coordinates, cumulative operating hours, echo intensity, signal-to-noise ratio, pressure value, water temperature and other related data.

2. Data Preprocessing and Processing
Outliers are removed through data cleaning, and the dataset is divided into training set/validation set/test set at a ratio of 7:2:1. A performance decay index is calculated based on equipment performance parameters, and a baseline health model is established. A multi-level annotation system is set up:
- Level 1 label: Healthy / Degraded (determined based on whether core indicators deviate from the baseline by ±10%)
- Level 2 label: Initial degradation (1-2 indicators exceed the limit) / Intermediate degradation (3-4 indicators exceed the limit) / Severe degradation (key indicators exceed the limit by ±30%)

3. Model Selection and Initialization
A hybrid XGBoost and LSTM model is adopted, with initial parameters set and hyperparameters optimized: dynamically adjusted learning rate of 0.01-0.001, dynamically adjusted batch size of 32-64, dynamically adjusted time step of 12-24; an equipment health assessment module is integrated.

4. Model Training
Distributed training is implemented based on PyTorch, with mixed-precision training (FP16) adopted to improve efficiency. Training duration is set, and data augmentation is used to simulate different aging scenarios, adding effects such as bubble interference, biological fouling, and sensor corrosion. An early stopping mechanism (patience=20) is configured, and gradient clipping is performed with max_norm=1.0.

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 is also set up: single parameter abnormality → multi-parameter abnormality, standard environment → extreme environment
