DETAILED DESCRIPTION

[0036] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0037] See also Figures 1 to 7As shown, a unit integrated module water supply management system of the present invention includes a water quality management module 1, a tap water pressurizing module 2 and a clean energy module 3, which can realize intelligent water supply management. The water quality management module 1 is arranged between the municipal water pipeline and the total water inlet end of the unit residential building, and the tap water transported by the municipal water pipeline is subjected to multiple filtrations through a multi-stage filtering device 11. The water quality intelligent control unit 12 in the water quality management module 1 monitors water quality data (such as turbidity, pH value, residual chlorine, etc.) in real time, and dynamically adjusts the filtration level of the multi-stage filtering device 11 according to the monitored data to ensure that the tap water entering the residential building meets the set water quality standards. The tap water pressurizing module 2 is arranged on the water supply pipeline in the unit residential building, and is used to adjust the pressure of the water supply network according to the user's water consumption and the water pressure changes of the municipal water pipeline, so as to ensure that a stable water supply pressure can still be provided during peak water use or when the municipal water pressure fluctuates. The clean energy module 3 is composed of a power generation device 31 and an energy storage device 32. The power generation device 31 can supply power to the system through renewable energy sources such as solar energy and energy. When the power generation device 31 generates excess electricity, the energy storage device 32 stores the excess electricity and releases the stored electricity when renewable energy generation is insufficient or when electricity demand is at a peak, thereby ensuring the continuous operation of the water quality management module 1 and the tap water pressurization module 2.

[0038] Through the implementation of the present invention, the unit integrated module water supply management system can effectively improve the water quality, stability and energy-saving efficiency of the water supply to residential buildings. The water quality intelligent control unit 12 in the water quality management module 1 ensures that the municipal water supply reaches the safe and clean water quality standards after multi-stage filtration, and provides healthy water that meets user needs. The tap water pressurization module 2 can dynamically adjust the water supply pressure according to the water pressure in the water supply network, ensuring that the water supply stability and adequacy in the residential building can be maintained even during peak water use or when the municipal water pressure is unstable; the pressurization module adopts a modular design, and the pump body of the modular variable frequency pressurization pump group has unified parameters. According to the occupancy rate of the unit residential building, the number of the pump bodies is increased or decreased to meet the different water consumption requirements caused by changes in the occupancy rate in the unit residential building.

[0039] At the same time, the clean energy module 3 uses renewable energy such as solar energy or hydropower to effectively reduce the system's dependence on traditional power grids, and has the environmental protection effect of energy saving and emission reduction. When power generation is insufficient or demand is at a peak, the energy storage device 32 can also release the stored electricity in time to ensure the continuous operation of the water supply system, thereby improving the energy utilization efficiency of the system and further reducing the operating cost of the water supply system.

[0040] In actual implementation, a water quality prediction model based on big data and machine learning algorithms can be introduced. It can predict water quality fluctuations in advance based on historical water quality data and changes in external factors such as weather and environment, and adjust the working mode of the filtration equipment in advance to ensure water supply safety.

[0041] Specifically, the multi-stage filtering device 11 is composed of a coarse filter 111, a fine filter 112, an ultrafiltration device 113 and a water outlet device 114 in sequence. The water delivery end of the municipal water pipeline is connected to the coarse filter 111, and the coarse filter 111 is used to remove larger impurities and particles in the tap water. The fine filter 112 further filters out smaller suspended matter and impurities, and the ultrafiltration device 113 removes fine suspended matter, bacteria and some viruses through microporous membrane filtration. In order to ensure that the water is not contaminated again during the transportation process and maintain the safety of the water quality, some residual chlorine is retained. The amount of residual chlorine retained needs to be strictly controlled within the range required by the specification, which can ensure the disinfection effect without causing potential threats to human health. The purified water is sent to the total water inlet end of the unit residential building through the water outlet device 114 to ensure the safety and cleanliness of the water used by the residents.

[0042] Through the step-by-step filtration of the multi-stage filtration device 11, comprehensive purification treatment is achieved from municipal water supply to unit residential buildings to ensure that the water quality meets the standards. The combined use of the coarse filter 111, the fine filter 112, and the ultrafiltration device 113 can effectively remove various impurities, bacteria, viruses, organic matter, dissolved solids and other pollutants in the tap water, thereby improving the water quality and meeting the high-standard water needs of users. The design of the filtration process enables different filters to perform their respective functions, prolongs the service life of each stage of filtration equipment, and reduces maintenance frequency and operating costs.

[0043] Specifically, the water quality intelligent control unit 12 includes a sampling device 121, a water quality sensor 122 and a control system 123. The sampling device 121 is installed between the municipal water pipeline and the multi-stage filtration device 11, and can extract water samples from the municipal water pipeline in real time and transport the water samples to the water quality sensor 122. The water quality sensor 122 is used to monitor key water quality parameters such as residual chlorine, turbidity, pH value, conductivity, TOC, COD, TDS, etc. in the water sample in real time.

[0044] In this embodiment, the sampling device 121 includes a first drive motor 1211, a crank-connecting rod mechanism 1212 and a sample barrel 1214. A faucet connected to the municipal water supply pipeline is arranged in the pipeline between the municipal water supply pipeline and the multi-stage filtering device 11. A rotating handle 1213 is provided at the end of the crank-connecting rod assembly. The first drive motor 1211 drives the rotating handle 1213 to rotate the faucet through the crank-connecting rod assembly to extract tap water in the municipal water supply pipeline into the sample barrel 1214. The water quality sensor 122 is arranged in the sample barrel 1214 for real-time monitoring of various parameters of water quality and transmitting the parameters to the control system 123. The control system 123 automatically adjusts the filtration level and working state of the multi-stage filtering device 11 according to the changes in these water quality parameters to ensure that the filtering equipment can specifically treat tap water with different degrees of pollution and realize refined management of water quality.

[0045] The control system 123 is connected to the multi-stage filtering device 11 to ensure that when the water quality sensor 122 detects abnormal changes in specific parameters in the water sample, the filtering process is adjusted in time to achieve the best filtering effect and water safety. The control system 123 can also combine the monitoring data of the water quality sensor 122 to determine the service life of the filter elements at each level in the multi-stage filtering device 11, and automatically prompt the user to replace the filter element (by installing intelligent display terminals on each floor of the unit residential building, comprehensively displaying the real-time water supply status of the system, the operating status of the filtering equipment, the working status of the pressurizing equipment, and the working status of the power supply equipment, etc.), to ensure the continuity of the filtering effect.

[0046] The tap water is monitored and feedback-controlled in real time through the water quality intelligent control unit 12 to ensure that the water quality in the municipal water pipeline can be continuously maintained at a high standard. At the same time, through the automatic adjustment of the multi-stage filtration equipment 11 by the control system 123, the filtration strategy can be flexibly adjusted according to different water quality conditions, avoiding the problem of unstable water supply quality caused by water quality fluctuations. Compared with traditional static filtration equipment, this solution not only improves the filtration efficiency and equipment life, but also reduces the frequency of manual intervention, improves the intelligence and automation level of the water supply system, and ensures the safety and high quality of users' water.

[0047] Specifically, the tap water pressurizing module 2 is composed of a non-negative pressure device 21, a modular variable frequency pressurizing pump group 22, a water pressure sensor 23 and a variable frequency controller 24. The non-negative pressure device 21 is installed between the municipal water supply pipeline and the multi-stage filtering device 11, and is used to ensure that the water pressure of the tap water entering the multi-stage filtering device 11 from the municipal pipeline is stable, thereby avoiding the water supply being affected by insufficient or fluctuating water pressure in the municipal pipeline. The modular variable frequency pressurizing pump group 22 is installed between the multi-stage filtering device 11 and the water supply pipeline of the unit residential building, and is responsible for pressurizing the tap water treated by the multi-stage filtering device 11 and delivering it to each user in the residential building.

[0048] The water pressure sensor 23 is arranged at the output end of the modular variable frequency booster pump group 22, and is used to monitor the pressure data of the pressurized tap water in real time. The frequency conversion controller 24 automatically adjusts the operating frequency of the modular variable frequency booster pump group 22 according to the water pressure data transmitted by the water pressure sensor 23, so as to ensure that the water supply pressure is always kept within the set range, so as to meet the water supply needs of users on different floors.

[0049] By using historical data on user water consumption and combining it with intelligent algorithms to predict future water demand, the pressurization module can adjust the water supply pressure in advance to avoid sudden drops in water pressure or waste of energy.

[0050] The pressurization module can effectively avoid the impact of water pressure fluctuations in the municipal water supply network on the stability of water supply in residential buildings through the application of the non-negative pressure device 21, and ensure that the multi-stage filtration equipment 11 can obtain a stable water source. At the same time, the modular variable frequency pressurization pump group 22 is linked with the water pressure sensor 23 and the variable frequency controller 24 to achieve automatic adjustment of the water supply pressure, adjust the working state of the pump group according to the actual water demand, and avoid the problem of excessive pressurization or insufficient pressure. Compared with the traditional fixed pressurization system, this solution can dynamically respond to changes in factors such as floor height and water consumption, ensure the water supply pressure of high-rise residents, and significantly improve the energy saving and operation efficiency of the water supply system.

[0051] In actual use, by collecting long-term water supply pressure and water consumption data, a user water use habit model can be established to predict the peak water use period in advance, automatically adjust the working mode of the booster pump group, and reduce energy consumption. In combination with the Internet of Things technology, the booster module is connected to the remote monitoring platform to achieve real-time monitoring of the operating status of the modular variable frequency booster pump group 22, automatically detect abnormal operating conditions and issue early warnings, so as to facilitate timely maintenance and prevent water supply interruptions.

[0052] Specifically, the water quality management module 1 further includes a direct drinking water supply unit 13 and a domestic water supply unit to meet the diverse needs of residents in residential buildings for different water quality uses. Among them, the direct drinking water supply unit 13 is composed of a disinfection device 131 and a drinking water pipeline 135. The disinfection device 131 has an outer cylinder 132, an ultraviolet disinfection device 133 arranged in the outer cylinder 132, and a shunt water inlet pipe 134. The shunt water inlet pipe 134 is wound in the outer cylinder 132. The ultraviolet disinfection device 133 is used to irradiate the shunt water inlet pipe 134 in the outer cylinder 132 with ultraviolet light to kill bacteria that may exist in the shunt water inlet pipe 134. The drinking water pipeline 135 is directly connected to the user's kitchen or direct drinking water equipment to ensure that the tap water treated by the multi-stage filtration device 11 meets the direct drinking standard. A first water distribution end and a second water distribution end are provided on the household water supply pipe of each user in the unit residential building. The first water distribution end is connected to the drinking water delivery pipe 135 through a disinfection device 131. The disinfection device 131 performs secondary treatment on the tap water after multi-stage filtration to remove harmful substances such as microorganisms and bacteria to ensure safe and hygienic water quality.

[0053] Intelligent valves are installed at the first water distribution end and the second water distribution end, and the distribution ratio of direct drinking water and domestic water is automatically adjusted according to the water consumption and water quality requirements through the control system 123 to ensure flexible scheduling of different water use scenarios. A water quality sensor 122 is installed in the direct drinking water pipeline 135 to monitor water quality changes in real time. When an abnormality is detected, the disinfection device 131 is automatically triggered to strengthen the treatment or cut off the water supply to ensure the safety of residents' drinking water.

[0054] The drinking water delivery pipeline 135 adopts plastic-coated copper pipes or stainless steel pipes to prevent secondary pollution, and delivers the treated tap water to the user's kitchen or drinking water equipment to meet the high-standard water needs of residents for direct drinking or food preparation. The domestic water supply unit is connected to the household non-direct drinking water water use place through the second water distribution end, and the tap water treated by the multi-stage filtration device 11 is directly delivered to the bathing, cleaning and other use places. This module ensures that the different needs of residents for drinking water and non-direct drinking water are effectively met through the reasonable allocation of water supply routes. The plastic-coated copper pipe combines the advantages of copper material (such as antibacterial, corrosion resistance and stability) and the protection of plastic coating (such as anti-scaling, anti-condensation and insulation performance), providing higher durability and water quality safety for the water delivery pipeline. This design effectively reduces the risk of secondary pollution and ensures the high quality of drinking water delivered to users.

[0055] This solution realizes the differentiated management of water supply to residents and fully guarantees the high quality and safety of direct drinking water. By adopting a combination of multi-stage filtration and disinfection devices 131, the tap water is finely treated to ensure that the quality of direct drinking water meets food hygiene standards and meets the needs of users for high-quality drinking water; at the same time, copper pipes or stainless steel pipes are used as drinking water pipelines 135 to prevent secondary pollution and improve the hygiene and reliability of the water supply system. The domestic water supply unit directly transports the water treated by the multi-stage filtration equipment 11 to non-direct drinking water places to avoid waste of resources and ensure the efficient operation of the water supply system. This differentiated water supply solution not only improves the comfort of residents' water use, but also realizes the rational use of water resources.

[0056] During actual implementation, a sewage recovery and purification module can be added at the end of the system (the domestic water drainage end of the unit residential building), and the discharged domestic sewage can be reused after filtering and treatment for non-direct drinking water purposes such as landscape irrigation and cleaning, further realizing the recycling and conservation of water resources.

[0057] Specifically, the integrated water supply management system includes a central control unit, which is connected to the water quality management module 1, the tap water pressurization module 2 and the clean energy module 3, aiming to realize intelligent and comprehensive control of the water supply system. The central control unit obtains water quality parameters, tap water pressure requirements and clean energy supply and demand status in real time through data interconnection with the water quality sensor 122, the water pressure sensor 23 and the clean energy monitoring device, forming dynamic feedback of the water supply system. Based on the acquired data, the central control unit can specifically adjust the operating parameters of the filtering and disinfection device 131 of the water quality management module 1 to ensure the stability and safety of the output water quality.

[0058] At the same time, the central control unit adjusts the operating status of the modular variable frequency booster pump group 22 in the tap water booster module 2 according to the real-time water pressure data to meet the water supply pressure requirements of different time periods and different floors. In addition, the central control unit also monitors the power supply status of the clean energy module 3. When the energy supply is insufficient or the power consumption is at peak, it optimizes the power distribution between modules to ensure the continuous and stable operation of the system. Each module is connected to the central control unit through a data link to achieve mutual cooperation and ensure the intelligent management and efficient operation of the entire water supply system.

[0059] The solution builds an integrated and intelligent water supply management system through the unified scheduling and management of each module by the central control unit. The central control unit dynamically adjusts the working status of the water quality management module 1 and the tap water pressurization module 2 according to the real-time water quality and water pressure data to ensure that the water supply quality and pressure are always in the best state, and improve the safety and comfort of residents' water use. At the same time, the central control unit intelligently allocates the clean energy module 3 to achieve efficient use of energy, reduce the system's operating costs and dependence on external electricity, and reflect the characteristics of green environmental protection. Compared with traditional water supply systems, this integrated management system has a higher level of automation and the ability to respond to emergencies, ensuring the stability and sustainability of water supply.

[0060] Specifically, the clean energy module 3 of the integrated water supply management system uses one or a combination of water energy or solar energy to solve the power supply and energy saving and environmental protection problems of the residential building water supply system. The power generation equipment 31, a hydroelectric generator set or a solar photovoltaic panel 311, can be flexibly combined or used one by one according to the site conditions to build a diversified renewable energy power supply system. The hydroelectric generator set converts water energy into electrical energy, and the solar photovoltaic panel 311 converts solar energy into electrical energy, and converts the DC power generated by each into the AC power required by the water supply system through an inverter.

[0061] Each power generation unit is connected to the central control unit, which monitors the power generation of clean energy and the electricity demand of residential buildings in real time, gives priority to clean energy when the power supply is sufficient, and switches to the municipal power grid when necessary. This module is connected to the water quality management module 1 and the tap water pressurization module 2 to ensure that all parts of the water supply system can operate normally under different energy supply conditions. Through the dynamic scheduling of the clean energy module 3 by the central control unit, efficient utilization of various energy forms and real-time management of the balance of power supply and demand are achieved.

[0062] In this embodiment, the clean energy module 3 is powered by a photovoltaic power generation system. The photovoltaic power generation system is composed of photovoltaic panels and energy storage equipment 32. It adopts a self-generated and self-used mode. According to the power of the electrical equipment of the integrated water supply system, photovoltaic panels of corresponding areas are configured to generate electricity. When there is sufficient sunshine, photovoltaic power generation is used for equipment, and the excess power is stored through the energy storage device 32. At night or on rainy days, the equipment is powered. In the most unfavorable state, energy can be stored during the valley power supply to ensure stable power consumption of the equipment. The photovoltaic power generation system is managed by an intelligent platform, and the power consumption mode can be intelligently adjusted according to the power consumption of the electrical equipment to ensure stable operation of the equipment.

[0063] By introducing renewable energy sources such as hydropower and solar energy, the dependence on traditional municipal electricity can be effectively reduced, and the green and low-carbon operation of the water supply system can be achieved. The real-time regulation of the clean energy module 3 by the central control unit enables the system to flexibly select and combine various renewable energy sources according to different environmental and climatic conditions, thereby improving energy utilization efficiency. At the same time, during peak power consumption or insufficient clean energy supply, the system can automatically switch to the municipal power grid to ensure the continuous and stable operation of the water supply system and avoid water supply interruptions due to power supply problems. This design not only meets the residents' demand for reliable water supply, but also significantly reduces the operating cost of the system, reflecting the advantages of energy saving, environmental protection and high efficiency.

[0064] A unit integrated module water supply management method comprises the following steps:

[0065] S1, water pretreatment, a water quality management module 1 is set between the municipal water pipeline and the main water inlet end of the unit residential building, and the water quality management module 1 includes a multi-stage filtration device 11 and a water quality intelligent control unit 12. The water quality intelligent control unit 12 uses sensors to monitor the key water quality parameters of the tap water transported by the municipal water pipeline in real time, including residual chlorine, turbidity, pH value, temperature, conductivity, TOC, COD and TDS data. The multi-stage filtration device 11 performs multi-stage treatment on the tap water to remove suspended matter, particulate matter and other impurities to ensure that the water quality meets the corresponding hygiene standards. This step is intended to solve the hidden dangers of residents' water safety caused by fluctuations in the quality of municipal water supply.

[0066] S2. Differentiated water supply. In the residential building, the water supply end of each user's household water supply pipe is respectively provided with a direct drinking water supply unit 13 and a domestic water supply unit. The direct drinking water supply unit 13 performs secondary disinfection on the tap water after multi-stage filtration, such as ultraviolet disinfection or ozone disinfection, to ensure that the water quality meets the drinking water standard, and delivers it to the kitchen and drinking water equipment for direct drinking or food preparation. The domestic water supply unit directly delivers the tap water after multi-stage filtration to the toilet, washing machine and other places where drinking water is not used directly, realizing the management of differentiated water supply and improving the rational use of water resources.

[0067] S3, pressurized water supply, a tap water pressurizing module 2 is set between the water quality management module 1 and the water inlet end of the user's household water supply pipeline. It includes a modular variable frequency pressurizing pump group 22, which can automatically adjust the water supply pressure according to the floor height, real-time water consumption and the pressure of the municipal water pipeline. The pressurizing module adopts a modular design, and the pump body of the modular variable frequency pressurizing pump group is a unified parameter. According to the occupancy rate of the unit residential building, the number of the pump bodies is increased or decreased to meet the different water consumption requirements caused by the change in the occupancy rate in the unit residential building. Through the intelligent regulation of the water demand of users on different floors, the water pressure of each floor is ensured to be constant, the problem of insufficient water supply pressure for high-rise residents is solved, and at the same time, waste or damage to facilities caused by excessive water pressure for low-rise residents is avoided.

[0068] S4. Water meter management. In the residential building, smart remote water meters are installed on the household water supply pipes of each user. The water meters are connected to the central control unit through wireless communication modules. The smart water meters record and monitor the user's water consumption data in real time, and upload the data to the central control unit for remote monitoring, water consumption analysis and billing management. The smart remote water meter has a camera meter reading module, which is used to capture the water consumption information image displayed by the smart remote water meter and upload the image to the central control unit. The central control unit is used to convert the image into a real-time meter reading. The background can trace the meter reading image and meter reading. The central control unit can also perform automatic adjustment and maintenance according to the user's water consumption to improve management efficiency.

[0069] S5, clean energy power generation and energy storage power supply, configure clean energy power generation equipment 31 and energy storage equipment 32 for water quality management module 1 and tap water pressurization module 2. Power generation equipment 31 can select solar energy or hydropower according to site conditions, convert external renewable energy into electrical energy, and provide power support for water quality management and pressurized water supply modules. Energy storage equipment 32 is used to store electrical energy when power generation equipment 31 generates excess electricity, and release the stored electrical energy when clean energy power supply is insufficient or when electricity consumption is at peak, to ensure continuous and stable operation of the system and reduce dependence on the municipal power grid.

[0070] By setting up the water quality management module 1 and the water quality intelligent control unit 12, the water quality treatment process can be monitored in real time and dynamically adjusted to ensure that the tap water meets the safety and sanitation standards, and effectively reduce the impact of pollutants and water quality fluctuations on the health of residents. Through the differentiated water supply system, different water qualities can be used in different scenarios to optimize the efficiency of water resource utilization, which not only ensures the safety of drinking water, but also avoids the waste of domestic water. The tap water pressurization module 2 ensures the stability of the water supply pressure on different floors through frequency conversion regulation, improves the water use experience, saves energy and reduces maintenance costs. The combination of intelligent remote water meter and central control unit realizes the accurate monitoring and remote management of water consumption, and improves the management efficiency and transparency of the water supply system. By using clean energy power generation and energy storage technology, the green and low-carbon operation of the water supply system is realized, the dependence on external power supply is reduced, and the energy utilization efficiency and system stability are improved.

[0071] Specifically, the water quality management module 1 in step S1 performs multiple filtrations on the tap water transported by the municipal water pipeline through the multi-stage filtration device 11 to ensure that the water quality meets the standard. The multi-stage filtration device 11 includes: a coarse filter 111, which is used to remove large particle impurities in the tap water, such as sediment and suspended matter; a fine filter 112, which is used to further filter out smaller particles and colloids; an ultrafiltration device 113, which is used to intercept tiny suspended matter, bacteria, viruses and other microorganisms in the water; the tap water is processed by the above-mentioned filtering devices in turn, and then transported to the total water inlet end of the unit residential building.

[0072] The water quality intelligent control unit 12 in the water quality management module 1 monitors the water quality parameters such as residual chlorine, turbidity, pH value, temperature, conductivity, TOC, COD and TDS of tap water in the municipal water pipeline in real time through sensors connected to each filtering device. When the monitored parameters exceed the set range, the water quality intelligent control unit 12 will issue an adjustment instruction to adjust the operating status of the filtering equipment to ensure that the filtered water quality meets the drinking water standards. The entire system works in coordination through the central control unit to ensure the stable operation of the multi-stage filtering equipment 11 and the water quality monitoring module.

[0073] By automatically adjusting the working status of each filter device, the system can not only flexibly adjust under different water quality conditions to ensure water quality safety, but also significantly improve the overall efficiency of the water supply system, reduce the cost and error of manual monitoring, and ensure the long-term reliability and low maintenance of the system.

[0074] Specifically, in another embodiment, in step S5, a photovoltaic power generation system is used as a clean energy power generation device 31 to generate electric energy for the water supply system of the unit residential building. The solar photovoltaic panel 311 is installed on the roof of the unit residential building, and the solar energy is converted into electric energy through the solar panel; the energy storage device 32 includes a control box 312 and a battery pack 321 which are connected to each other. The power generated by the photovoltaic panel is stored by the battery pack 321, and the control box 312 integrates electrical components such as circuit breakers, relays, and fuses. The control box 312 is connected to the central control system 123 to receive signals sent by the central control system 123 to distribute power to different loads of the system.

[0075] In actual use, a hydroelectric power generation system can be used, combined with a small water flow or rainwater recycling system or by utilizing the floor difference of a residential building, to use the water flow to drive a turbine to generate electricity. The power generation system converts the generated energy into electricity that can be used by the equipment through an inverter.

[0076] The clean energy power generation system is connected to the energy storage device 32, which uses a high-efficiency battery module (such as a lithium-ion battery) to store the excess electricity generated by the power generation device 31. The energy storage device 32 is connected to the water quality management module 1 and the tap water pressurization module 2 of the water supply system to meet the power demand of the system. When the power generation system generates insufficient electricity, the energy storage device 32 automatically releases the stored electricity to ensure the continuous operation of the system; when the power generation system has sufficient electricity, the excess electricity is stored to cope with peak power consumption or insufficient power generation. The overall power management of the system is monitored and adjusted by the central control unit to ensure that the clean energy power generation and the energy storage device 32 work together efficiently to achieve energy balance in the self-generation mode.

[0077] The various options for photovoltaic power generation and hydropower generation adapt to the environmental conditions of different regions and residential buildings, and realize the efficient use of renewable energy. The addition of energy storage equipment 32 ensures that the water supply system can still operate stably when the energy supply fluctuates. In particular, when photovoltaic power generation is limited by natural conditions, energy storage equipment 32 can provide backup power and reduce the demand for municipal power supply. In actual implementation, photovoltaic and hydropower systems can be intelligently integrated, and the central control unit can automatically dispatch the use ratio of different energy sources according to real-time weather and electricity demand to optimize energy utilization efficiency.
