2、 Requirement analysis

Pipeline explosion problem: Pipeline explosion is a major hidden danger to urban water supply safety. The continuous occurrence of pipeline explosions, especially super large explosions, poses a great threat to water supply, with significant economic losses and adverse social impacts. In severe cases, it can cause casualties.

Secondary pollution of water quality in the pipeline network: Currently, the water quality of the effluent from China's water plants has been basically controlled within the national drinking water hygiene standards. However, pipeline bursts or transmission and distribution facilities, as well as secondary water supply facilities, have affected the water quality, and the pipeline network has become a bottleneck for improving the water supply quality.

Pipeline leakage and resource waste: Due to prolonged operation or external damage, urban pipelines suffer from varying degrees of pipeline leakage, which not only wastes valuable water resources but also affects the economic benefits of the water supply industry.

The scheduling capability is relatively weak: the operation of water plants and booster pump stations overly relies on manpower, and even some water supply still relies on manual operation, making it difficult to schedule and control the overall pipeline network situation.

4、 Monitoring content

1. Leakage, bursting, pipe leakage, leakage monitoring

By installing leak monitoring devices at intervals of 50-300 meters in the water supply network, or installing hydrophones every 500 meters, remote real-time monitoring of pipeline leaks (leaks, leaks, bursts) can be achieved; When there is a water leakage in the pipeline network, the friction between the pipe wall and the water flow generates a sound signal. The pipeline leakage monitoring device will transmit the collected sound signal to the platform through wireless communication. The platform will actively identify the water leakage signal through artificial intelligence algorithms, confirm the leakage point, and visually display it on the map, and synchronously send alarm notifications.

2. Pressure and flow monitoring

By installing pipeline pressure monitoring devices, electromagnetic flow meters, etc. in various water supply zones, real-time monitoring of pressure and flow can be achieved. Combined with leakage monitoring and leakage positioning algorithms, leakage zones can be quickly and efficiently found and dealt with, thereby reducing the frequency of leakage and pipe bursting, improving maintenance efficiency, reducing losses, ensuring water supply quality, achieving scientific warning, reducing costs, and improving efficiency.

5、 System advantages

Reduce maintenance costs: By monitoring the operation status of the water supply network, potential problems can be detected in a timely manner and preventive maintenance can be carried out to avoid accidents such as pipeline leakage and bursting, thereby reducing maintenance costs.

Improving emergency response capability: By real-time monitoring of the water supply network, abnormal situations can be detected in a timely manner, and emergency measures can be taken in a timely manner to avoid water supply accidents.

Optimizing water resource management: By monitoring the operation status and water quality of the water supply network, the usage and distribution of water resources can be understood, thereby optimizing the management and allocation of water resources, avoiding waste and unreasonable use of water resources.

Leakage monitoring of water supply networks is an important means to ensure the safety of urban water supply. By real-time monitoring of the operation status, water quality, and other conditions of the water supply network, it can effectively avoid serious consequences such as insufficient water supply and water pollution, and ensure the safety and hygiene of residents' drinking water. At the same time, the municipal pipeline network urban water supply pipeline leakage and burst monitoring system can also improve water supply efficiency, reduce operating costs, and provide important support for the construction of smart cities. Build a comprehensive knowledge base, policy analysis model library, and intelligence research method library related to decision-making themes, and continuously improve the auxiliary decision-making system of the water supply system to provide intelligent decision support and knowledge services for water dispatch decision-making.
