The working principle of smart water is mainly based on the integrated application of modern information technology. Through the Internet of Things, cloud computing, big data, artificial intelligence and other advanced technologies, intelligent, automated and refined management of water supply, drainage, water quality monitoring and other water management processes is realized. The following is a detailed description of the working principle of smart water:
1、 Data acquisition and transmission
Internet of Things technology: the intelligent water system uses the Internet of Things technology to install sensors, controllers, data acquisition instruments, gateways and other equipment at key locations such as pump stations, pipelines, canals, sewage treatment plants, etc. These equipment can collect various data of the water supply system in real time, such as water quality parameters (pH value, turbidity, residual chlorine, etc.), water volume, water pressure, equipment operation status, etc.
Data acquisition and transmission: the sensor converts the collected data into processable information and transmits it to data processing in real time through wired or wireless networks (such as 4G, WiFi, Ethernet, etc.). This process ensures the accuracy and timeliness of data.
2、 Data processing and analysis
Cloud computing and big data technology: data processing uses cloud computing and big data technology to store, process and analyze massive data. Through in-depth data mining and statistical analysis, the operation rules and potential problems of the water supply system can be revealed.
Artificial intelligence and machine learning: combining artificial intelligence and machine learning technology, build a prediction model, automatically identify abnormal conditions, optimize water supply scheduling, and improve management efficiency. For example, by analyzing historical data, future water demand can be predicted, so as to formulate a reasonable production plan; At the same time, problems such as pipe network leakage and water pollution can be found in time, and corresponding treatment measures can be taken.

3、 Intelligent decision and control
Intelligent decision-making: based on the results of data analysis, the intelligent water system can generate auxiliary decision-making suggestions to help managers make more scientific and reasonable decisions. For example, in the event of an emergency, the system can quickly assess the scope of impact, develop an emergency plan, and notify the relevant responsible person for handling.
Intelligent control: the system supports multiple control modes (such as local manual control, remote control, automatic control, centralized management, etc.), which can be flexibly switched according to the actual situation. Through intelligent control cabinet, intelligent valve and other equipment, the remote control and automatic adjustment of the water supply system can be realized to ensure the safety and stability of water supply.
4、 Comprehensive management and service
Monitoring: The smart water system realizes the perception and real-time monitoring of the water supply system, including water quality, water volume, water pressure, equipment status and other aspects. This will help to find and solve problems in time and improve the safety and reliability of water supply.
Fine management: through data analysis and intelligent control, the system can achieve fine management of the water supply system. For example, optimize the operation of pump stations, reduce energy consumption, reduce the difference between production and sales, etc; At the same time, it can also provide users with a more convenient service experience.
Visual display: the system provides a variety of visual display methods (such as data report, curve chart, GIS map, etc.) to help managers intuitively understand the operation status and various indicators of the water supply system. This helps to improve management efficiency and service level.
To sum up, the working principle of smart water is to realize the perception, intelligent analysis and scientific decision-making of water supply system through modern information technology, so as to promote the modernization and intelligent development of water management.
