[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Digital twinning is a technology that simulates real-world physical entities, processes, or systems within an information platform. This is achieved by creating a digital model that is completely equivalent to the physical entity. This digital model can reflect the entity's status in real time and can be controlled and optimized. The core of digital twin technology lies in data collection, modeling, analysis, and feedback. Digital twinning can be defined as a process that fully utilizes data from physical models, sensor updates, and operational history, integrating multidisciplinary, multi-physics, multi-scale, and multi-probabilistic simulation processes to complete mapping in virtual space. This reflects the entire lifecycle of the corresponding physical equipment or system, establishes a real-time monitoring system, and feeds real-time data back to the digital twin model, enabling real-time monitoring of the physical system. Through model predictions, problems can be identified in advance and control strategies adjusted to ensure stable system operation.

[0023] The digital twin-based water supply network leakage detection system utilizes digital twin technology for real-time monitoring and leakage detection of water supply networks. The system first conducts detailed mapping and statistics of the water supply network. Sensor terminals are then installed on the network to collect data such as pressure and noise. Pattern recognition models are used to identify and detect individual points to identify anomalies. Once an anomaly is confirmed, precise location determination using techniques such as graph convolution is performed to ultimately pinpoint the leak. This system enables more effective management and control of the water supply network, reduces leakage rates, and conserves water resources. By abstracting the water supply network into a hydraulic topology, the system can identify anomalies and locate outliers from a global perspective. By combining advanced sensor technology, pattern recognition, graph convolutional networks, and digital twin technology, the digital twin-based water supply network leakage detection system provides an efficient and accurate solution for leak detection in water supply networks, helping to improve the safety and efficiency of water supply systems.

[0024] Although there are many abnormal leakage detection devices on the market, they still face some problems and challenges in actual application. During the detection process, existing detection devices are usually susceptible to the impact of water flow at the end of the water supply pipeline, causing the equipment and sensors to shake, making data analysis complicated, directly affecting the quality of data collection, resulting in leakage points being missed or incorrectly located, and reducing the accuracy of leakage detection.

[0025] See also Figure 1-Figure 4The utility model provides an embodiment: an abnormal leakage detection device for a water supply network based on digital twins, comprising a support platform and a positioning assembly; a positioning assembly for limiting a device to prevent it from shaking is installed on the upper end of the support platform 1, and the positioning assembly comprises a collar 201, a limiting plate 202, a screw 203, a limiting bar 205, a monitoring module 206, an acoustic wave sensor 210, and a connecting ring 211. Two sets of collars 201 are welded on the bottom of the support platform 1, and limiting plates 202 are symmetrically provided on the inner side of the collar 201.

[0026] See also Figure 1-Figure 2 In this embodiment, two sets of screws 203 are provided at the outer end of the limiting plate 202, and the screws 203 extend to the outer end through the collar 201, and a nut 204 is fixed on the end of the screw 203 away from the collar 201. The interior of the limiting plate 202 is respectively provided with a through hole and a threaded hole for accommodating the screws 203. By using two sets of screws 203 to assist the limiting plate 202 to fit and tighten the position according to the diameter width of the sensor terminal, the contact between the device and the water supply network is closer, reducing data errors caused by sensor shaking or position changes, and improving data accuracy. Multiple sets of limiting strips 205 are laid on the bottom of the support platform 1, and the multiple sets of limiting strips 205 are adhered and fixed to the support platform 1. The limiting strips 205 are used to assist the support platform 1 to fit the outer end of the water supply network, reducing equipment wear caused by contact surface friction of the sensor, extending the service life of the sensor, and reducing maintenance costs.

[0027] See also Figure 1-Figure 3 In this embodiment, a monitoring module 206 is fixed to the upper end of the support platform 1, and two sets of transmission rods 207 are provided on the upper end of the monitoring module 206. The two sets of transmission rods 207 are electrically connected to the monitoring module 206. The monitoring module 206 is used to centrally process the data collected by the sensor, and the transmission rods 207 efficiently transmit the data to the central processing device, adapting to the transmission requirements of different environmental data, ensuring stable operation under various environmental conditions, improving the transmission stability of the equipment, and ensuring subsequent data analysis and processing. Two sets of connecting cables 208 are provided at the outer end of the monitoring module 206. The connecting cables 208 are electrically connected to the monitoring module 206. The ends of the two sets of connecting cables 208 away from the monitoring module 206 are both provided with acoustic wave sensors 210. By using two sets of acoustic wave sensors 210 for detection, more data points are provided.

By using the plurality of welding blocks 212 to assist in welding the acoustic wave sensor 210 to the water supply network terminal, the acoustic wave sensor 210 is firmly installed at the water supply network terminal, reducing the shaking of the sensor caused by water flow impact or external factors, and improving the overall stability.

By using the connecting ring 211, the sensor can be replaced to meet different detection needs, flexibly responding to different environments, and improving the accuracy of collected data.

[0029] When working, first, two sets of rings 201 are used in combination with the limiting plate 202 to assist the device to be installed at the water supply network sensor terminal. According to the diameter width of the sensor terminal, a single set of screws 203 is used to preferentially be inserted into the threaded hole so that the limiting plate 202 fits tightly with the terminal. After the single set of screws 203 is positioned, another set of screws 203 is used to insert the auxiliary limiting plate 202 into the through hole to fit and tighten the limit, thereby reducing data errors caused by sensor shaking or position changes. While fixing the support plate 1, multiple sets of limiting strips 205 laid on the bottom of the support plate 1 fit with the outer end of the water supply network, reducing the equipment wear caused by contact surface friction of the sensor, and realizing the preliminary positioning of the device and the terminal, so that it provides stable and reliable data input, ensuring that the data can be accurately fed back to the digital twin model for model calibration and optimization. After the support plate 1 is assembled, a welding gun is used to weld the welding block 212 to the designated detection position to fix the acoustic wave sensor 210 so that it is firmly installed at the water supply network terminal to reduce the shaking of the sensor caused by water flow impact or external factors. During the detection process, two sets of acoustic wave sensors 210 are used for detection to provide more data points. By comparing and analyzing the two sets of data, abnormal leakage events in the water supply network can be more accurately identified and located. The auxiliary device collects data from different angles and positions to comprehensively cover the monitoring area. The connecting cable 208 transmits the data collected by the acoustic wave sensor 210 to the monitoring module 206 for centralized processing. Secondly, the transmission rod 207 efficiently transmits the data to the central processing unit to adapt to the transmission requirements of different environmental data, ensure stable operation under various environmental conditions, and ensure subsequent data analysis and processing.
