Description

Technical Field

[0001] This application relates to the field of secondary water supply technology, specifically to secondary water supply control methods, systems, media, and equipment. Background Technology

[0002] With social development, secondary water supply systems are being widely used and rapidly developed. More and more new buildings are adopting secondary water supply systems. Secondary water supply refers to the establishment of an auxiliary water supply system on the basis of the urban water supply system to meet the water needs of specific places. It is a flexible and efficient water supply method.

[0003] Secondary water supply systems are particularly crucial in high-rise buildings, where various events are frequently held, leading to significant water demand. Traditional secondary water supply systems are often ill-suited to handle unexpected events in high-rise buildings, such as business buildings, including meetings and events, potentially resulting in insufficient water supply or waste. Therefore, effectively predicting and meeting fluctuating water demands is a pressing issue in the field of secondary water supply. Summary of the Invention

[0004] This application provides a secondary water supply control method that can effectively predict and meet the fluctuating water supply demand for events held in high-rise buildings, thereby improving water supply efficiency.

[0005] In a first aspect, this application provides a secondary water supply control method, the method comprising: Obtain floor information and event information for the target floor in a high-rise building where an event will be held. The floor information includes the floor height and the water supply equipment information corresponding to the target floor. Determine the target water pressure for the target floor based on the floor height and water supply equipment information; Predict the water supply demand information for the target floor based on the activity information; The water supply decision for the target floor is determined based on the target water pressure and the water demand information.

[0006] By adopting the above technical solution, and by acquiring floor information and activity information of the target floor in a high-rise building, it is possible to accurately predict the water supply demand during temporary activities. By combining the floor height and water supply equipment parameters, the actual available water pressure of the target floor after considering the flow loss of the pipeline network can be scientifically and accurately determined. Then, based on different activity information, the water supply demand information can be intelligently predicted. By comparing the target water supply pressure with the predicted water demand, a precise water supply decision plan can be formulated that both ensures water supply security and avoids water oversupply. This effectively predicts and meets the changing water supply demand of activities held in high-rise buildings, and improves water supply efficiency.

[0007] Optionally, the water supply equipment information includes pipe length, pipe diameter, and pipe volumetric flow rate. Determining the target water supply pressure for the target floor based on the floor height and the water supply equipment information includes: determining the theoretical water pressure corresponding to the target floor based on the floor height; calculating the pressure loss based on the pipe length, pipe diameter, and volumetric flow rate; and adjusting the theoretical water pressure based on the pressure loss to obtain the target water supply pressure.

[0008] By adopting the above technical solution, the theoretical water pressure value is first calculated based on the floor height. Then, the pipeline pressure loss is calculated based on the length, diameter, and volumetric flow rate parameters of the water supply pipeline. This allows for the assessment of the impact of hydraulic losses under actual operating conditions. Finally, the target water supply pressure for the target floor is obtained by combining the pressure loss calculation results. This fully considers the combined impact of static head pressure and dynamic flow loss on the actual water supply pressure, making the target water pressure calculation more accurate and comprehensive.

[0009] Optionally, calculating the pressure loss based on the pipe length, the pipe diameter, and the volumetric flow rate includes: determining the water flow velocity based on the volumetric flow rate and the pipe diameter; substituting the water flow velocity, the pipe length, and the pipe diameter into the pressure loss calculation formula to obtain the pressure loss; the pressure loss calculation formula is as follows: In the formula, H is the pressure loss, f is the loss factor, L is the pipe length, D is the pipe diameter, V is the water flow velocity, and g is the gravitational acceleration.

[0010] By adopting the above technical solution, the actual velocity of the water flow is determined based on the volumetric flow rate and diameter parameters of the pipeline when calculating pressure loss. The flow velocity directly reflects the impact of flow rate on pipeline friction loss. The pressure loss calculation formula can evaluate the loss effect of water flow state on pressure transmission under different pipe diameters and lengths. Because flow rate and pipeline geometric parameters are considered, the calculation results can accurately reflect the actual hydraulic characteristics inside the pipeline, achieving accurate and efficient pressure loss calculation.

[0011] Optionally, the activity information includes the activity type, activity schedule, and number of participants. Predicting the water supply demand information of the target floor based on the activity information includes: matching the corresponding water volume prediction model in the prediction model library according to the activity type, wherein the prediction model library includes multiple activity types and corresponding water volume prediction models; and inputting the number of participants and the activity schedule into the water volume prediction model to obtain the water supply demand for each time period.

[0012] By adopting the above technical solution, a water supply prediction model library for different types of activities has been established. The models corresponding to different types of activities can fully consider the specific water consumption characteristics of such activities. By matching the activity type and selecting the appropriate prediction model, and then inputting the activity details, such as the number of people and time distribution, the water demand in different time periods can be accurately predicted.

[0013] Optionally, the water supply equipment information includes rated water pressure, and the step of determining the water supply decision for the target floor based on the target water supply pressure and the water supply demand information includes: extracting the water supply demand in each time period from the water supply demand information, and calculating the actual demand water pressure corresponding to the water supply demand in each time period; determining the water supply decision for the target floor based on each actual demand water pressure and the target water supply pressure, wherein the water supply decision includes the planned water supply pressure in each time period.

[0014] By adopting the above technical solution, the water demand for different time periods is extracted from the prediction results, and the actual water pressure demand for the corresponding time period is calculated. The actual water pressure demand can directly reflect the real-time status of the water supply system during the event. Then, based on the comparison between the actual water pressure demand and the target water pressure, the rationality of the water pressure for each time period relative to the target water pressure is judged, thereby determining the planned water pressure for each time period. Water resources can be allocated in real time according to the event, which not only ensures water supply safety but also achieves precise water use and improves water supply efficiency.

[0015] Optionally, determining the water supply decision for the target floor based on the actual water pressure demand and the target water supply pressure includes: determining whether the actual water pressure demand is less than the target water supply pressure; if the actual water pressure demand is less than the target water supply pressure, then the actual water pressure demanded in each time period is used as the corresponding planned water supply pressure; if there is an overpressure period where the actual water pressure demand is not less than the target water supply pressure, then the target water supply pressure is used as the planned water supply pressure for the overpressure period, and the water consumption of each water-using area of ​​the target floor during the overpressure period is obtained, and a backup water supply decision for the overpressure period is determined based on the water consumption.

[0016] By adopting the above technical solution, when making water supply decisions, the relationship between the actual demand water pressure and the target water supply pressure for each time period is determined. When the actual demand water pressure is lower than the target water pressure, the actual demand water pressure is used as the planned water supply pressure to meet the water demand for that time period. When there is an overpressure period where the actual demand water pressure exceeds the target water supply pressure, a backup water supply plan is determined based on the real-time water consumption data of each water-using area. This allows for a rapid response to sudden large water demand and improves water supply efficiency.

[0017] Optionally, determining the backup water supply decision within the overpressure period based on the water consumption of each of the aforementioned water uses includes: obtaining the water use priority weight of each of the aforementioned water use areas within the overpressure period, and obtaining the maximum water supply that the target water supply pressure can provide according to the water use priority weight of each of the aforementioned water use areas, and allocating the maximum water supply to each of the aforementioned water use areas to obtain the allocated water consumption of each of the aforementioned water use areas; and using the allocated water consumption of each area as the backup water supply decision.

[0018] By adopting the above technical solution, the maximum available water volume is allocated among the regions according to their weights, prioritizing the water demand of regions with high weights. The allocation result is the backup water supply decision, which can ensure that the water supply of important regions is prioritized under limited water volume conditions, and can meet the basic water demand of important regions to the greatest extent.

[0019] A second aspect of this application provides a secondary water supply control system, the system comprising: The floor activity information acquisition module is used to acquire floor information and activity information of the target floor in the high-rise building where the activity is to be held. The floor information includes the floor height and the water supply equipment information corresponding to the target floor. The target water supply pressure determination module is used to determine the target water supply pressure of the target floor based on the floor height and water supply equipment information. A water supply demand information determination module is used to predict the water supply demand information of the target floor based on the activity information; The water supply decision determination module is used to determine the water supply decision for the target floor based on the target water supply pressure and the water supply demand information.

[0020] A third aspect of this application provides a computer storage medium storing a plurality of instructions adapted for loading by a processor and executing the method steps described above.

[0021] A fourth aspect of this application provides an electronic device comprising: a processor and a memory; wherein the memory stores a computer program adapted to be loaded by the processor and to execute the method steps described above.

[0022] In summary, one or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. This application can accurately predict water supply demand during temporary events by obtaining floor information and activity information of the target floor of a high-rise building. By combining the floor height and water supply equipment parameters, it can scientifically and accurately determine the actual available water pressure of the target floor after considering the flow loss of the pipeline network. Then, based on different activity information, it can intelligently predict water supply demand information. By comparing the target water supply pressure with the predicted water demand, it can formulate a precise water supply decision plan that can both ensure water supply security and avoid water oversupply. This can effectively predict and meet the changing water supply demand of events held in high-rise buildings and improve water supply efficiency. 2. This application first calculates the theoretical water pressure value based on the floor height, and then calculates the pipeline pressure loss based on the length, diameter and volume flow parameters of the water supply pipeline. This can assess the impact of hydraulic loss under actual operating conditions.

This fully considers the combined impact of static head pressure and dynamic flow loss on the actual water supply pressure, making the target water pressure calculation more accurate and comprehensive. 3. This application extracts the water demand for different time periods from the prediction results and calculates the actual water pressure required for the corresponding time periods. The actual water pressure required can directly reflect the real-time status of the water supply system during the event. Then, based on the comparison between the actual water pressure required and the target water pressure, the rationality of the water pressure for each time period relative to the target water pressure is judged, thereby determining the planned water pressure for each time period. Water resources can be allocated in real time according to the event, which not only ensures water supply safety but also achieves precise water use and improves water supply efficiency.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0028] Please refer to Figure 1 A flowchart illustrating a secondary water supply control method is presented. This method can be implemented using a computer program, a microcontroller, or run on a secondary water supply control system, or as a standalone application. Specifically, the method includes steps 10 to 40, as follows: Step 10: Obtain the floor information of the target floor in the high-rise building where the event will be held, as well as the event information. The floor information includes the floor height and the water supply equipment information corresponding to the target floor.

[0029] The application can be implemented in the secondary water supply system of any high-rise building, such as high-rise commercial buildings like office buildings and financial centers. These buildings frequently host various business meetings, exhibitions, and company annual meetings, resulting in large and frequently changing water consumption, which traditional water supply systems often struggle to adapt to. They can also be used in high-end hotels and entertainment venues, which frequently host group activities such as banquets, parties, and performances, involving a large number of participants and complex floor areas, requiring the secondary water supply system to provide refined support. Furthermore, they can be used in high-rise residential buildings, apartments, etc., without any limitation.

[0030] This application requires obtaining floor information and activity information of the target floor in a high-rise building as the basis for subsequent water supply control. Floor height is directly related to the head pressure of the water supply system and is a crucial parameter for calculating the target water supply pressure. Head pressure refers to the pressure exerted by a fluid due to its own weight; it is a static pressure exerted on water by gravity. Water supply equipment information determines the actual condition of the water supply system, while activity information is used to predict changes in water demand during activity. Obtaining comprehensive and accurate basic information is a prerequisite for achieving overall water supply control.

[0031] Specifically, floor information may include, but is not limited to, floor height and water supply equipment information corresponding to the target floor. The floor height can be multi-story or single-story. Users can enter the floor number of the event through the floor selection interface, and the system can query the height data of that floor. Water supply equipment information can be extracted from the building design database. Event information allows users to fill in the event type, schedule, number of participants, etc., and can also be cross-checked with the meeting room reservation system.

[0032] Step 20: Determine the target water pressure for the target floor based on the floor height and water supply equipment information.

[0033] Specifically, the target floor height determines the static head pressure, while the specific parameters of the water supply pipes affect the dynamic pressure loss during water transmission. Only by considering both factors can the accurate, loss-compensated target water supply pressure value be calculated. The floor height can be found in the building data based on the target floor where the event will be held. Then, the corresponding water supply pipe length, diameter, and other parameters can be extracted. The floor height data and pipe parameters are then substituted into the hydraulic calculation formula to calculate the theoretical static pressure and flow loss dynamic pressure. Finally, by combining the static pressure and flow loss dynamic pressure, the target water supply pressure value considering the dynamic flow factors is obtained. This target water supply pressure fully considers the combined effects of floor head pressure and pipe hydraulic characteristics, resulting in a more accurate and reasonable calculation, and providing a more scientific and reliable basis for subsequent water supply control. The calculated target water pressure value ensures the water supply needs of users while considering the actual hydraulic conditions of the pipe network, achieving the optimal balance point of the water supply system and greatly improving the system's intelligence level.

[0034] Based on the above embodiments, as an optional embodiment, the step of determining the target water supply pressure for the target floor according to the floor height and water supply equipment information may further include the following steps: Step 201: Determine the theoretical water pressure corresponding to the target floor based on the floor height.

[0035] Specifically, the floor height data is extracted from the acquired target floor information. This floor height is then directly input into the water head pressure calculation formula to obtain the theoretical maximum static pressure value of that floor based on its height. This theoretical pressure only considers the floor's water head and does not include the influence of pipe network flow. This theoretical value represents the upper limit of water pressure for that floor, providing a benchmark for subsequent actual pressure calculations considering pipe flow loss effects. The water head pressure calculation formula is: p = ρgh, where P is the theoretical water pressure and ρ is the density of water, generally taken as 1000 kg / m³. 3 h is the water height, and g is the acceleration due to gravity, taken as 9.8 m / s². 2 .

[0036] Step 202: Calculate the pressure loss based on the pipe length, pipe diameter, and volumetric flow rate.

[0037] Specifically, considering the impact of flow movement on pressure during pipeline transmission, pressure loss is a dynamic hydraulic factor and must be calculated in conjunction with pipeline parameters to obtain a true and reliable water supply pressure value. The flow velocity (v) can be determined based on the volumetric flow rate (Q) and the pipe diameter. The flow velocity v can be calculated using the volumetric flow rate (Q) and the pipe cross-sectional area (A), i.e., v = Q / A. For a circular pipe, the cross-sectional area A can be calculated using the pipe diameter (D), i.e., A = π(D / 2)². Substituting the flow velocity, pipe length, and pipe diameter into the pressure loss calculation formula yields the pressure loss, which is: In the formula, H is the pressure loss in meters, f is the loss factor, which needs to be calculated by looking up a table or using an approximate formula based on the relative roughness of the pipe (determined by the pipe material) and the Reynolds number (determined by the density, velocity, viscosity and pipe diameter of the water flow), L is the pipe length, D is the pipe diameter, V is the water flow velocity, and g is the acceleration due to gravity.

[0038] Step 203: Adjust the theoretical water pressure based on pressure loss to obtain the target water supply pressure.

[0039] Specifically, pressure loss caused by resistance is due to the resistance encountered by water flowing through the pipe. This resistance consumes some kinetic energy, resulting in a decrease in water pressure. Therefore, we need to add this pressure loss to the theoretical water pressure to ensure that water can be effectively delivered to the target floor. The pressure loss H caused by resistance is added to the theoretical water pressure to obtain the adjusted target water supply pressure. The formula for calculating the theoretical water pressure is P = ρgh, and the formula for calculating the adjusted target water supply pressure is P' = ρg(h + H). By adjusting the theoretical static water pressure for dynamic water pressure loss, the calculation results consider both the influence of head pressure and the evaluation of transmission dynamics factors, making the final target water supply pressure value closer to the actual situation. This achieves an organic combination of static and dynamic hydraulic characteristics, enabling the water supply control system to more accurately and comprehensively judge the target pressure state, thereby formulating a more reasonable and effective water supply decision-making scheme.

[0040] Step 30: Predict the water supply demand information for the target floor based on the activity information.

[0041] Specifically, the system retrieves information such as activity type, schedule, and number of participants from the activity details. Based on the activity type, it matches a corresponding water demand prediction model, trained on historical data for that type of activity. Then, the detailed activity information is input into the model for simulation and prediction, yielding the water demand for each future time period. This intelligent model predicts the dynamic water demand for activities, rather than simply relying on empirical estimations. The prediction results closely match actual conditions, enabling the system to clearly understand future water demand trends. Before peak water usage arrives, the system can proactively manage water resources, ensuring the security of water supply for activities.

[0042] Based on the above embodiments, as an optional embodiment, the step of predicting the water supply demand information of the target floor based on activity information may further include the following steps: Step 301: Match the corresponding water volume prediction model in the prediction model library according to the activity type. The prediction model library includes multiple activity types and their corresponding water volume prediction models.

[0043] Step 302: Input the number of participants and the activity schedule into the water demand prediction model to obtain the water demand for each time period.

[0044] Specifically, a prediction model library is established for different activity types. Because water usage patterns vary across different activity types, targeted models are needed to improve prediction accuracy. First, detailed water usage records are collected from past events, such as conferences, exhibitions, and performances, including event schedules, number of participants, and actual water consumption at different stages. These collected water usage records are then categorized by activity type, creating a separate historical water usage dataset for each type. Using machine learning algorithms and historical event information from these datasets as input samples, a water usage prediction model is trained independently for each activity type dataset. This results in water usage prediction models for various activities such as conferences, exhibitions, and performances, forming a complete model library.

[0045] Furthermore, based on the activity type information, a matching water consumption prediction model is searched in the model library. This model library contains pre-trained models for various activities such as conferences, exhibitions, and performances. After selecting the water consumption prediction model corresponding to the activity type, further detailed activity information, such as the number of participants and time segmentation, is input into the selected water consumption prediction model for simulation prediction. The water consumption prediction model will comprehensively consider factors such as the number of participants and the schedule, and dynamically output water consumption results for different time periods.

[0046] Step 40: Determine the water supply decision for the target floor based on the target water pressure and water demand information.

[0047] Specifically, the target water supply pressure reflects the system's ability to provide water pressure, while water demand information corresponds to actual water usage at different times. Combining the two allows us to determine whether the system's water supply capacity can meet actual demand, helping to formulate practical water supply decisions. First, based on the established target water supply pressure and the predicted water demand information for each time period, we determine whether the target pressure can meet the predicted water consumption. If it can, then corresponding water supply decisions are made based on the predicted water consumption. If the pressure is insufficient to meet peak water consumption, backup water supply measures will be activated, such as using backup pumps or reducing water usage, to ensure that water demand during critical periods is met.

[0048] Based on the above embodiments, as an optional embodiment, the step of determining the water supply decision for the target floor based on the target water pressure and water demand information may further include the following steps: Step 401: Extract the water demand for each time period from the water demand information, and calculate the actual water pressure required for each time period.

[0049] Specifically, extracting the water demand for each time period and calculating the corresponding actual water pressure is crucial for quantitatively analyzing water usage at different times, serving as an important basis for water supply decisions. Detailed water demand data for each time period is extracted from the predicted water demand information. Then, based on hydraulic principles and the water flow rate at different times, the corresponding water pressure parameters are calculated, which represent the actual water pressure demand for each time period. By quantitatively analyzing the actual water consumption and corresponding water pressure for each time period, the different demand levels on the system's water supply capacity at different times can be clearly identified. The system can then identify peak water consumption periods and develop specific water supply plans to ensure that peak water demand is met.

[0050] Step 402: Based on the actual water pressure demand and the target water supply pressure, determine the water supply decision for the target floor. The water supply decision includes the planned water supply pressure for each time period.

[0051] Specifically, calculating the actual water pressure demand for each time period allows for a clear assessment of the specific water usage situation. Comparing this demand with the target water pressure the system can provide identifies periods where the supply capacity is either sufficient or insufficient. By comparing the actual demand with the target water pressure for each time period, if the target water pressure is greater than or equal to the actual demand, the actual demand is used as the planned water pressure for that period. If the target water pressure is less than the actual demand, backup water supply measures are activated, such as through pipeline scheduling or utilizing backup water sources, to increase the planned water pressure and ultimately form the planned water pressure scheme for each time period.

[0052] Based on the above embodiments, as an optional embodiment, the water supply decision for the target floor is determined based on the actual water pressure demand and the target water supply pressure. The water supply decision includes the step of determining the planned water supply pressure for each time period, and may also include the following steps: Step 4021: Determine whether the actual required water pressure is less than the target water supply pressure.

[0053] Step 4022: If the actual water pressure demand is less than the target water supply pressure, then the actual water pressure demand in each time period shall be used as the corresponding planned water supply pressure.

[0054] Specifically, for each time period, the actual water pressure demand is compared with the target water supply pressure value to determine whether each actual water pressure demand is less than the target water supply pressure. If each actual water pressure demand is less than the target water supply pressure, then the actual water pressure demand is used as the planned water supply pressure for each time period, and the system's water supply capacity can meet the needs of these time periods.

[0055] Step 4023: If there is an overpressure period during which the actual demand water pressure is not less than the target water supply pressure, then the target water supply pressure is used as the planned water supply pressure for the overpressure period, and the water consumption of each water area on the target floor during the overpressure period is obtained. Based on the water consumption, the backup water supply decision for the overpressure period is determined.

[0056] Specifically, if the actual water pressure demand exceeds the target water supply pressure, it is identified as an overpressure period. The system will adopt the target water supply pressure as the planned water supply pressure for these periods. At the same time, it will analyze the water demand of each water-using area during the overpressure period to formulate a targeted backup water supply plan to ensure that these important water-using areas can still obtain sufficient water supply during the overpressure period.

[0057] The process of determining the backup water supply plan can be as follows: First, obtain the water usage priority weights for each water-using area during the overpressure period, and the maximum backup water supply volume that can be provided under the target water pressure conditions. To ensure a reasonable allocation of backup water supply based on the priority of water-using areas when the backup water supply volume is limited, the maximum backup water supply volume is allocated according to the priority weights of each area; areas with higher priority weights receive a larger allocation. Finally, the specific allocation of water supply volume that each water-using area can obtain during the overpressure period is determined, and these allocation plans will serve as the overall backup water supply decision. Priorities can be scientifically allocated according to the importance of the water-using areas' activity levels, ensuring that the water needs of important areas are met first, achieving reasonable allocation of water supply during overpressure periods, and significantly improving the water supply system's allocation optimization and adaptive capabilities.
