[0002] In modern society, the safety of the water supply system is directly related to people's life and health and the quality of life. The supply of clean and safe drinking water is the basis for maintaining human health, promoting economic development and social stability. However, with the acceleration of industrialization and urbanization processes, as well as the impact of global climate change, the existing water supply technologies are facing a series of severe challenges in ensuring water quality safety, as follows: (1) The aggravation of water source pollution: With the increase in industrial activities, untreated or substandard wastewater is directly discharged into natural water bodies such as rivers and lakes, resulting in excessive levels of harmful substances such as heavy metals and organic pollutants; moreover, the excessive use of pesticides and fertilizers enters the groundwater system through rainwater runoff and infiltration, causing eutrophication of water bodies and the accumulation of toxic substances; in addition, during the urbanization process, the discharge of domestic sewage in densely populated areas surges, and if the treatment facilities are imperfect or overloaded, it will also seriously pollute the water source.

[0003] (2) Problems in the water transmission and distribution system: The water supply pipeline systems in many areas were built in the last century, and most of the materials are cast iron or cement, which are prone to corrosion and leakage. This not only causes waste of water resources, but also may become the source of secondary water quality pollution; in addition, the aging pipeline system is also prone to pipeline abandonment problems, thus causing water supply safety problems.

[0004] (3) Monitoring problems: The existing solutions lack effective online water quality monitoring equipment and early warning systems, making it difficult to detect and handle water quality problems in a timely manner.

[0021] The following will elaborate on the preferred embodiments of the present invention in conjunction with the drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] In the description of the present invention, it should be noted that the embodiments described in the present invention are some embodiments of the present invention, rather than all embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0023] In the specification, claims and the above-mentioned drawings of this document, terms such as "first", "second", etc. are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this document described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment. Embodiment 1

[0024] This embodiment provides a high-security water supply method, as Figure 1 and Figure 2 shown, including the following steps: S100, Multi-directional monitoring step: In this step, the water quality, water pressure, and flow rate are monitored respectively, and the safety risk situation in the water supply system is determined based on these data, specifically as follows: For example, a water quality sensor is installed in the water supply pipeline to monitor key indicators such as turbidity, residual chlorine, pH value, and heavy metal content in the water in real time; once water quality abnormalities are found, the safety risk situation is judged as a first-level risk situation, an alarm is immediately issued, and corresponding measures are taken for treatment; For example, the pressure sensor is used to monitor the water pressure change in the water supply pipeline to ensure that the water pressure is maintained within a reasonable range. Excessive water pressure may cause the pipeline to burst, while too low water pressure may affect the normal water use of users; when the water pressure is too high, the safety risk situation is judged as a first-level risk situation, an alarm is immediately issued, and corresponding measures are taken for treatment; For example, a flow sensor is used to monitor the water flow velocity and flow rate in the water supply pipeline in real time, and the water use situation is grasped in real time, providing a basis for the reasonable allocation and scheduling of water resources. When the water flow velocity is too fast and exceeds the preset threshold, the safety risk situation is judged as a first-level risk situation, an alarm is immediately issued, and corresponding measures are taken for treatment; For example, key equipment such as water pumps and valves in the water supply system are monitored in real time, including parameters such as operating current, temperature, and vibration; once abnormalities are found, the safety risk situation is judged as a second-level risk situation, and maintenance and repair are immediately carried out to avoid water supply interruption accidents caused by equipment failures.

[0025] S200, Multi-directional response step: In this step, timely alarm, rapid repair, and simulation emergency are adopted to respond to and avoid early warning of the safety risk situation in a timely manner, specifically as follows: For example, establish an intelligent alarm system that automatically issues an alarm when the water quality, water pressure, or equipment operating status is abnormal, and notifies relevant personnel via text messages, emails, etc. For example, establish a risk location repair system that intelligently obtains the corresponding risk location when a safety risk occurs and directly notifies the repair team of this location to improve the on-site repair efficiency. In addition, use drone technology to quickly detect problems in the water supply network and provide accurate image information for emergency response. For example, use simulation software to establish a water supply system pipeline topology structure diagram and a repair team distribution structure diagram that conforms to the actual situation. Use simulation software to regularly simulate risk situations in the water supply system pipeline, simulate the optimal routes from each repair team distribution point to the risk location of the water supply system pipeline, and record the optimal routes as route support when a risk situation occurs.

[0026] S300, Fire prevention treatment steps: In this step, carry out fire prevention layout for the water supply system to improve the normal operation of the water supply system in an accidental fire environment, and further improve the water supply safety of the water supply system, specifically as follows: For example, in the design and construction of the water supply system, preferentially select materials and equipment with good fire prevention performance. For example, use flame-retardant cables, fireproof coatings, etc. For example, set up isolation measures such as firewalls and fire doors at key parts of the water supply system to prevent the spread of fire.

[0027] For example, establish a backup fire water supply system to ensure that sufficient fire water and short-term temporary water can be provided in a timely manner through the fire water supply system when a fire occurs, and provide backup water supply energy when the water supply system breaks down due to a fire.

[0028] S400, Multi-layer filtration and disinfection steps: In this step, perform multi-level filtration of the water source in multiple links of the water supply system to effectively improve the water quality safety, specifically as follows: For example, before the water source enters the water treatment facility, perform pretreatment filtration to remove large particulate impurities and suspended solids in the water. For example, during the water treatment process in the water treatment facility, adopt deep filtration technologies such as sand filtration, carbon filtration, ultrafiltration, and nanofiltration to further remove tiny particles, organic matter, bacteria, etc. in the water. During the water treatment process, adopt disinfection technologies such as chlorine disinfection, ozone disinfection, and ultraviolet disinfection to kill pathogenic microorganisms in the water and ensure water quality safety. For example, install terminal filters such as activated carbon filters and ultrafiltration membrane filters at the user end to further remove impurities and odors in the water and improve the water quality taste.

[0029] S500, Periodic water quality optimization steps: In this step, a neural network prediction model for water supply safety analysis is established. The input data are various water supply system indicators, such as water quality, water pressure, and equipment operation status, and the output result is the water supply safety score. The water supply system is comprehensively detected regularly, including aspects such as water quality, water pressure, and equipment operation status. The detected data are input into the above model, and according to the evaluation result output by the model, measures are taken in a timely manner for improvement and optimization. When the score is lower than 90 points, the equipment operation control plan is improved; when the score is lower than 80 points, the equipment operation control plan and the water pressure distribution plan are improved; when the score is lower than 70 points, the equipment operation control plan, the water pressure distribution plan, and the water quality filtration and purification plan are improved.

[0030] In summary, by comprehensively applying monitoring technology, timely response technology, fire prevention technology, and filtration and disinfection technology, a high-safety water supply system is established, which helps to ensure people's life and health and quality of life, and also helps to promote the sustainable development of the water supply industry.
