[0167] Step 6, system integration and optimization: used to integrate data collection, feature extraction, model training, prediction and positioning modules into a unified system; tune the system to ensure efficient collaboration between modules and adapt to different pipe network environments;
[0168] Step 7, real-time monitoring and early warning system: used to display the status of the pipe network and the prediction results in real time through the real-time data monitoring interface. When the system detects a potential water leakage risk, it can promptly notify the operation and maintenance personnel;

[0170] Step 9, testing and evaluation: Test the performance of the system in the actual pipe network environment, evaluate the detection accuracy, response speed and user satisfaction, and iteratively optimize the system based on the test results to meet higher performance requirements.
[0171] Data collection and preprocessing are used to deploy high-precision sensor networks to collect real-time data such as pressure, flow, and sound of the water supply network. Data cleaning, denoising, and standardization are implemented to improve data quality. Data lakes are built to integrate and store historical and real-time data to provide data support for analysis and model training. Figure 3 As shown, the specific steps include the following:
[0172] Step 1.1, sensor deployment: deploy various types of sensors at key nodes of the water supply network, including but not limited to pressure sensors, flow sensors, acoustic sensors, etc., to monitor the status of the network in real time;
[0173] Step 1.2, data acquisition: The data collected by the sensor is transmitted to the central database in real time through the data acquisition system; the data includes pressure readings, flow data, and sound signals;
[0174] Step 1.3, data cleaning: preprocess the collected data to remove invalid or erroneous data points through outlier detection and elimination;
[0175] Step 1.4, denoising: Apply signal processing techniques, including wavelet transform or filter, to remove noise components in the data and improve signal clarity;
[0176] Step 1.5, data standardization: convert data of different dimensions and magnitudes into a unified format for easy subsequent processing and analysis;

[0178] Step 1.7, Data storage: Build a data lake to store cleaned and standardized data, including historical data and real-time data streams;
[0179] In the denoising process, the filter formula used is: y(t) = ∫x(τ)h(t-τ)dτ;
[0180] Where x(τ) is the original signal, y(t) is the filtered signal, and h(t-τ) is the impulse response of the filter;
[0181] Data normalization formula: In the formula, x is the original data, z is the standardized data, μ is the mean of the data, and σ is the standard deviation of the data.
[0182] Emergent feature extraction is used to automatically extract high-level features related to water leakage from preprocessed data using deep learning models such as convolutional neural networks (CNN), recurrent neural networks (RNN), or Transformer models. Self-supervised learning tasks are designed to learn feature representations of water leakage from data in an unsupervised manner.
[0183] Emergence refers to the phenomenon that in a complex system, individual components interact according to simple rules without central control or guidance, thus generating new patterns, structures or behavioral characteristics. These new characteristics are not directly predicted from the characteristics of individual components, but are spontaneously generated in the process of interaction between multiple components. For example, the flocking flight of birds or the collective swimming of fish are not controlled by a single bird or fish, but are generated by the interaction of simple individual rules (such as following the bird or fish in front, avoiding collisions, etc.). For another example, the evacuation behavior of a crowd in an emergency is not controlled by a single individual, but is a collective behavior generated by individuals following simple rules (such as following others and staying away from danger).
[0184] Emergent phenomena study the behavior of complex systems and provide methods for designing more effective algorithms and systems. In water leakage detection technology, emergent phenomena refer to high-level features that are automatically discovered from a large amount of sensor data and can characterize water leakage behavior. These features may not be directly detectable by a single sensor or simple algorithm.
