[0021] Please refer to Figure 1 , Figure 1 The flowchart of a method for controlling constant pressure water supply in a dual-supply standardized pump room in some embodiments of the present application. The method for controlling constant pressure water supply in a dual-supply standardized pump room is used in terminal devices, such as computers, mobile phone terminals, etc. The method for controlling constant pressure water supply in a dual-supply standardized pump room includes the following steps: S11, obtaining multiple historical water supply data within a preset time period, including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data, and processing the water supply time data and the corresponding water pump water supply pressure data to obtain the water supply pressure level and the corresponding water supply pressure and water supply time; S12, processing the water supply pressure data of the user node and the water supply pressure corresponding to the water supply pressure level to obtain a pipeline pressure loss value corresponding to the water supply pressure level; S13, obtaining real-time water supply time point data, processing the real-time water supply time point data in combination with the water supply time corresponding to the water supply pressure level, obtaining the water supply pressure level and the corresponding water supply pressure and pipeline pressure loss value and processing them, and obtaining the real-time demand water supply pressure of the water pump, including the valley water supply demand pressure, the flat peak water supply demand pressure and the peak water supply demand pressure; S14, according to the real-time demand water supply pressure control water pump to implement water supply and obtain the real-time water supply pressure data of the user node, according to the real-time water supply pressure data of the user node, process and obtain the real-time water supply evaluation index; S15, comparing the real-time water supply evaluation index with a preset water supply evaluation threshold, and controlling the water supply mode adjustment according to the comparison result.

[0022] It should be noted that in order to achieve constant pressure water supply and precise control while reducing equipment energy consumption, firstly, by obtaining multiple historical water supply data including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data within a preset time period, the size of the water pump water supply pressure data and the corresponding time are classified and processed to obtain the water supply pressure level and the corresponding water supply pressure and water supply time. Then, the average of the water supply pressure data of multiple user nodes is calculated and the difference between the water supply pressure corresponding to the water supply pressure level is calculated to obtain the pipeline pressure loss value corresponding to the water supply pressure level. Then, the water supply pressure level is determined according to the real-time water supply time point data to obtain the corresponding water supply pressure and pipeline pressure loss value. The real-time demand water supply pressure of the water pump is obtained after summing. The water supply of the water pump is controlled with the real-time demand water supply pressure. The real-time water supply pressure data of the user node is obtained based on the pressure sensor installed at the user node. The real-time water supply pressure data of the user node is processed to obtain the real-time water supply evaluation index. Finally, it is determined whether it is necessary to control the water supply mode adjustment through threshold comparison.

[0023] Please refer to Figure 2 , Figure 2 It is a flow chart of obtaining the water supply pressure level and the corresponding water supply pressure and water supply time of a method for controlling constant pressure water supply in a dual-supply standardized pump room in some embodiments of the present application. According to an embodiment of the present invention, the acquisition of multiple historical water supply data within a preset time period, including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data, is performed according to the water supply time data and the corresponding water pump water supply pressure data, and the water supply pressure level and the corresponding water supply pressure and water supply time are obtained, including: S21, performing a threshold comparison between the water supply pressure data of the water pump and a preset water supply pressure threshold, wherein the water supply pressure threshold includes a preset first water supply pressure threshold and a preset second water supply pressure threshold, and the preset first water supply pressure threshold is less than the preset second water supply pressure threshold; S22. If the water supply pressure data of the water pump is less than the preset first water supply pressure threshold, it corresponds to the valley water supply pressure level, and the mean value and corresponding water supply time of the water supply pressure data of the water pump are the valley water supply pressure and valley water supply time corresponding to the valley water supply pressure level respectively; S23. If the water supply pressure data of the water pump is greater than or equal to the preset first water supply pressure threshold and less than the preset second water supply pressure threshold, then it corresponds to the flat-peak water supply pressure level, and the mean value of the water supply pressure data of the water pump and the corresponding water supply time are the flat-peak water supply pressure and the flat-peak water supply time corresponding to the flat-peak water supply pressure level respectively; S24. If the water supply pressure data of the water pump is greater than or equal to the preset second water supply pressure threshold, then corresponding to the peak water supply pressure level, the mean value of the water supply pressure data of the water pump and the corresponding water supply time are respectively the peak water supply pressure and peak water supply time corresponding to the peak water supply pressure level.

[0024] It should be noted that in order to more accurately control the water pump pressure to implement water supply, first, based on the pressure sensors arranged at the water pump outlet and the user's home entrance, multiple historical water supply data including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data within a preset time period are obtained. In this embodiment, the preset time period is set to 1 day, and the pressure data is obtained every 5 minutes. The multiple water pump water supply pressure data obtained are respectively compared with the preset water supply pressure threshold. The preset water supply pressure threshold includes a preset first water supply pressure threshold and a preset second water supply pressure threshold. In this embodiment, the preset first water supply pressure threshold is set to 0.3MPa, and the preset second water supply pressure threshold is set to 0.4MPa. If the water If the pump water supply pressure data is less than the preset first water supply pressure threshold, it corresponds to the valley water supply pressure level. By performing threshold comparison on multiple water pump water supply pressure data and the corresponding water supply times, multiple valley water supply pressures and corresponding valley water supply times can be obtained. For example, multiple water pump water supply pressure data that are continuously less than the preset first water supply pressure threshold, the earliest corresponding time is 22:30 and the latest time is 07:30. The average of all the water pump water supply pressure data obtained is 0.26MPa, then 0.26MPa is the valley water supply pressure, and 22:30-07:30 is the valley water supply time; similarly, multiple flat peak water supply pressures and corresponding flat peak water supply times and multiple peak water supply pressures and corresponding peak water supply times can be obtained.

[0025] Please refer to Figure 3 , Figure 3 It is a flow chart of obtaining the pipeline pressure loss value corresponding to the water supply pressure level of a method for controlling constant pressure water supply in a dual-supply standardized pump room in some embodiments of the present application. According to an embodiment of the present invention, the processing according to the water supply pressure data of the user node and the water supply pressure corresponding to the water supply pressure level to obtain the pipeline pressure loss value corresponding to the water supply pressure level includes: S31, according to the valley water supply time, the flat peak water supply time and the peak water supply time, respectively calculate the average of the corresponding user node water supply pressure data, and obtain the valley actual supply pressure, the flat peak actual supply pressure and the peak actual supply pressure on the user side corresponding to the valley water supply time, the flat peak water supply time and the peak water supply time; S32. Process the valley actual supply pressure, flat peak actual supply pressure and peak actual supply pressure on the user side with the valley water supply pressure, flat peak water supply pressure and peak water supply pressure respectively to obtain the valley pipeline pressure loss value, flat peak pipeline pressure loss value and peak pipeline pressure loss value corresponding to the valley water supply time, flat peak water supply time and peak water supply time.

[0026] It should be noted that, during the implementation of water supply, pipeline pressure loss values ​​may not be the same for different pressures and different pipeline layouts. In order to accurately obtain pipeline pressure loss values ​​corresponding to different situations, firstly, the water supply pressure data of multiple user nodes corresponding to the obtained valley water supply time, flat peak water supply time and peak water supply time are averaged respectively to obtain the valley actual supply pressure, flat peak actual supply pressure and peak actual supply pressure on the user side corresponding to the valley water supply time, flat peak water supply time and peak water supply time, and then process them with the valley water supply pressure, flat peak water supply pressure and peak water supply pressure to obtain the valley pipeline pressure loss value, flat peak pipeline pressure loss value and peak pipeline pressure loss value corresponding to the valley water supply time, flat peak water supply time and peak water supply time; The calculation formula for the valley pipeline pressure loss value is: ; in, is the trough pipeline pressure loss value, For low water supply pressure, Provides pressure for the low-peak period on the user side; The calculation formula for the flat peak pipeline pressure loss value is: ; in, is the peak pipeline pressure loss value, Peak water supply pressure, The actual supply pressure for the user side during peak hours; The peak pipeline pressure loss value calculation formula is: ; in, is the peak pipeline pressure loss value, is the peak water supply pressure, To meet the peak supply pressure on the user side.

[0027] According to an embodiment of the present invention, the real-time water supply time point data is obtained, and the real-time water supply time point data is processed in combination with the water supply time corresponding to the water supply pressure level, the water supply pressure level and the corresponding water supply pressure and pipeline pressure loss value are obtained and processed, and the real-time water supply demand pressure of the water pump is obtained, including the valley water supply demand pressure, the flat peak water supply demand pressure and the peak water supply demand pressure, including: Obtain real-time water supply time point data, and compare the real-time water supply time point data with the water supply time corresponding to the water supply pressure level; If the real-time water supply time point is the low-peak water supply time, then the low-peak water supply pressure and the corresponding pipeline pressure loss value are summed and calculated to obtain the low-peak water supply demand pressure of the water pump; If the real-time water supply time point is the flat-peak water supply time, then the flat-peak water supply pressure and the corresponding pipeline pressure loss value are summed and calculated to obtain the flat-peak water supply demand pressure of the water pump corresponding to the flat-peak water supply pressure level; If the real-time water supply time point is the peak water supply time, then corresponding to the peak water supply pressure level, the peak water supply pressure and the corresponding pipeline pressure loss value are summed and calculated to obtain the peak water supply demand pressure of the water pump.

[0028] It should be noted that in order to obtain the water supply pressure of the pump suitable for the current time, the real-time water supply time point data is first obtained, and the real-time water supply time point data is determined to belong to the valley water supply time, the flat peak water supply time or the peak water supply time according to the water supply time corresponding to the water supply pressure level. For example, if the real-time water supply time point is 06:00, which is the valley water supply time, the valley water supply pressure and the pipeline pressure loss value corresponding to the valley water supply pressure level are summed and calculated to obtain the valley water supply demand pressure of the water pump. For example, the valley water supply pressure is 0.26MPa and the pipeline pressure loss value is 0.02MPa, then 0.26+0.02=0.28MPa is the valley water supply demand pressure corresponding to the real-time water supply time point data; similarly, the flat peak water supply demand pressure and the peak water supply demand pressure corresponding to the real-time water supply time point data can be obtained.

[0029] Please refer to Figure 4 , Figure 4 It is a flow chart of obtaining a real-time water supply evaluation index of a method for controlling constant pressure water supply in a dual-supply standardized pump room in some embodiments of the present application. According to an embodiment of the present invention, the water supply pressure control water pump implements water supply according to real-time demand and obtains real-time water supply pressure data of user nodes, and processes the real-time water supply pressure data of user nodes to obtain a real-time water supply evaluation index, including: S41, controlling the water pump to supply water according to the water supply pressure in real time demand; S42, obtaining real-time water supply pressure data of the user node, and extracting peak pressure data and valley pressure data; S43, calculating according to the real-time water supply pressure data of the user node to obtain the node pressure variance; S44, inputting the peak pressure data, the valley pressure data and the node pressure variance into a preset real-time water supply evaluation model for processing to obtain a real-time water supply evaluation index.

[0030] It should be noted that after obtaining the real-time demand water supply pressure corresponding to the real-time water supply time point, the water pump is controlled according to the pressure to implement water supply, and the real-time water supply pressure data of the user node is obtained. First, the peak pressure data and the valley pressure data are extracted, and then the node pressure variance is obtained based on the obtained real-time water supply pressure data of multiple user nodes. For example, the obtained real-time water supply pressure data of the user node are 0.25, 0.27, 0.28, 0.28, 0.26, and 0.25MPa, the extracted peak pressure data is 0.28MPa, the valley pressure data is 0.25MPa, and the average value is 0.265MPa, [(0.26-0.265) 2 + (0.26-0.265) 2 + (0.26-0.265) 2 + (0.26-0.265) 2 + (0.26-0.265) 2 + (0.26-0.265) 2 ] / 6=0.000158 is the node pressure variance. The peak pressure data, valley pressure data and node pressure variance are input into the preset real-time water supply assessment model to obtain the real-time water supply assessment index. The real-time water supply evaluation index calculation formula is: ; in, For real-time water supply assessment index, , , They are peak pressure data, valley pressure data, and node pressure variance, , , It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the constant pressure water supply control platform).

[0031] According to an embodiment of the present invention, the real-time water supply evaluation index is compared with a preset water supply evaluation threshold, and the water supply mode is adjusted according to the comparison result, including: Comparing the real-time water supply assessment index with a preset water supply assessment threshold, wherein the preset water supply assessment threshold includes a first preset water supply assessment threshold, a second preset water supply assessment threshold, and a third preset water supply assessment threshold, and the first preset water supply assessment threshold is less than the second preset water supply assessment threshold, and the second preset water supply assessment threshold is less than the third preset water supply assessment threshold; If it is less than the first preset water supply assessment threshold, the auxiliary water pump is started synchronously to supply water; If it is greater than or equal to the first preset water supply assessment threshold and less than the second preset water supply assessment threshold, the auxiliary water pump is not turned on and the main water pump speed is automatically adjusted; If it is greater than or equal to the second preset water supply assessment threshold and less than the third preset water supply assessment threshold, no adjustment is made; If it is greater than or equal to the third preset water supply assessment threshold, the main water pump is turned off and the auxiliary water pump is turned on.

[0032] It should be noted that the obtained real-time water supply evaluation index is compared with the preset water supply evaluation threshold. In this embodiment, the preset water supply evaluation threshold is set to (0, 0.5), [0.5, 0.65), [0.65, 0.85), and [0.85, 1], which respectively correspond to synchronously starting the auxiliary water pump to supply water, not starting the auxiliary water pump, automatically adjusting the speed of the main water pump, not making any adjustment, shutting down the main water pump, and starting the auxiliary water pump; for example, the real-time water supply evaluation index obtained is 0.4, indicating that the water supply effect is poor, then the auxiliary water pump is started synchronously to supply water.

[0033] According to an embodiment of the present invention, if the water supply value is greater than or equal to the first preset water supply assessment threshold and less than the second preset water supply assessment threshold, the auxiliary water pump is not turned on and the main water pump speed is automatically adjusted, and then the following further includes: According to the real-time water supply evaluation index, a preset water supply evaluation index and water pump speed relationship mapping table is queried to obtain the required speed of the main water pump; The water supply of the main water pump is controlled according to the required speed of the main water pump.

[0034] It should be noted that in order to achieve precise control of the water pump, the preset water supply evaluation index and water pump speed relationship mapping table is queried according to the real-time water supply evaluation index obtained to obtain the main water pump demand speed. The preset water supply evaluation index and water pump speed relationship mapping table is generated after obtaining the water supply evaluation index of a large number of historical samples and the corresponding water pump speed analysis. After determining the main water pump demand speed, the main water pump water supply is controlled.

[0035] According to an embodiment of the present invention, the method of controlling the main water pump to supply water according to the required speed of the main water pump further includes: Obtain real-time water supply characteristic data of the main water pump, including flow data, head data and input power; Processing is performed according to the flow data, head data and input power to obtain the real-time water supply efficiency of the main water pump; Comparing the real-time water supply efficiency of the main water pump with a preset main water supply efficiency threshold; If it is less than the preset main water pump water supply efficiency threshold, an inefficient operation warning will be output; If it is greater than or equal to the main water pump water supply efficiency threshold, no processing will be performed.

[0036] It should be noted that the water pump is the main energy-consuming equipment in the standardized pump room. In order to meet the water supply demand and reduce energy consumption at the same time, the efficiency of the water pump should be guaranteed. The main water pump water supply should be controlled according to the determined main water pump demand speed, and the real-time water supply characteristic data of the main water pump including flow data, head data and input power should be obtained. The flow data, head data and input power should be input into the preset water pump water supply efficiency evaluation model for processing to obtain the real-time water supply efficiency of the main water pump. The calculation formula for the real-time efficiency of the main water pump water supply in the water pump water supply efficiency evaluation model is: ; in, Real-time efficiency of water supply to the main water pump, , , They are flow data, head data and input power respectively. is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the constant pressure water supply control platform); The obtained real-time water supply efficiency of the main water pump is compared with the preset main water supply efficiency threshold. In this embodiment, the main water supply efficiency threshold is set to (0, 0.8), [0.8, 1], and an inefficient operation warning is output correspondingly without adjustment. For example, if the obtained real-time water supply efficiency of the main water pump is 0.7, it means that the water pump efficiency is low, and an inefficient operation warning is output. If the obtained real-time water supply efficiency of the main water pump is 0.85, it means that the water pump efficiency is high, and no adjustment is made.

[0037] It is worth mentioning that according to an embodiment of the present invention, it also includes: Get the real-time pressure value of the city water at the preset node in front of the water pump; Processing the real-time city water pressure value and the preset city water standard pressure value to obtain the city water pressure deviation rate; Comparing the city water pressure deviation rate with a preset city water pressure deviation threshold, wherein the preset city water pressure deviation threshold includes a first preset city water pressure deviation threshold and a second preset city water pressure deviation threshold, and the first preset city water pressure deviation threshold is less than the second preset city water pressure deviation threshold; If it is less than the first preset city water pressure deviation threshold, the water pump is controlled to be turned off; If it is greater than or equal to the first preset city water pressure deviation threshold and less than the second preset city water pressure deviation threshold, a pressure loss warning is output; If it is greater than the second preset city water pressure deviation threshold, no adjustment is made.

[0038] It should be noted that during the water supply process, if there is a leakage, municipal water outage or other problems, the water pump cannot respond in time, which may cause damage to the water pump. Therefore, the real-time pressure value of the municipal water at the preset node in front of the water pump is first obtained, and processed with the preset municipal water standard pressure value to obtain the municipal water pressure deviation rate. For example, the real-time pressure value of the municipal water is 0.38MPa, and the preset municipal water standard pressure value is 0.4MPa, then (0.4-0.38) / 0.4=0.05 is the municipal water pressure deviation rate; the obtained municipal water pressure deviation rate is compared with the preset municipal water pressure deviation threshold. In this embodiment, the preset municipal water pressure deviation threshold is set to (0, 0.1), [0.1, 0.2), [0.2, 1], corresponding to no adjustment, output pressure loss warning, and control of water pump shutdown; for example, if the obtained municipal water pressure deviation rate is 0.05, it means that the deviation is not large, and no adjustment is made.

[0039] The present invention also discloses a dual-supply standardized pump room constant pressure water supply control system, comprising a memory and a processor, wherein the memory comprises a dual-supply standardized pump room constant pressure water supply control method program, and when the dual-supply standardized pump room constant pressure water supply control method program is executed by the processor, the following steps are implemented: Acquire multiple historical water supply data within a preset time period, including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data, and process the water supply time data and corresponding water pump water supply pressure data to obtain the water supply pressure level and the corresponding water supply pressure and water supply time; Processing is performed according to the user node water supply pressure data and the water supply pressure corresponding to the water supply pressure level to obtain a pipeline pressure loss value corresponding to the water supply pressure level; Acquire real-time water supply time point data, process the real-time water supply time point data in combination with the water supply time corresponding to the water supply pressure level, obtain the water supply pressure level and the corresponding water supply pressure and pipeline pressure loss value and process them, and obtain the real-time demand water supply pressure of the water pump, including the valley water supply demand pressure, the flat peak water supply demand pressure and the peak water supply demand pressure; According to the real-time demand water supply pressure, the water pump is controlled to implement water supply and obtain the real-time water supply pressure data of the user node. The real-time water supply pressure data of the user node is processed to obtain the real-time water supply evaluation index; The real-time water supply evaluation index is compared with a preset water supply evaluation threshold, and the water supply mode is adjusted according to the comparison result.

[0040] It should be noted that in order to achieve constant pressure water supply and precise control while reducing equipment energy consumption, firstly, by obtaining multiple historical water supply data including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data within a preset time period, the size of the water pump water supply pressure data and the corresponding time are classified and processed to obtain the water supply pressure level and the corresponding water supply pressure and water supply time. Then, the average of the water supply pressure data of multiple user nodes is calculated and the difference between the water supply pressure corresponding to the water supply pressure level is calculated to obtain the pipeline pressure loss value corresponding to the water supply pressure level. Then, the water supply pressure level is determined according to the real-time water supply time point data to obtain the corresponding water supply pressure and pipeline pressure loss value. The real-time demand water supply pressure of the water pump is obtained after summing. The water supply of the water pump is controlled with the real-time demand water supply pressure. The real-time water supply pressure data of the user node is obtained based on the pressure sensor installed at the user node. The real-time water supply pressure data of the user node is processed to obtain the real-time water supply evaluation index. Finally, it is determined whether it is necessary to control the water supply mode adjustment through threshold comparison.

[0041] According to an embodiment of the present invention, the method of obtaining a plurality of historical water supply data within a preset time period, including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data, and processing the water supply time data and the corresponding water pump water supply pressure data to obtain a water supply pressure level and the corresponding water supply pressure and water supply time, includes: Comparing the water supply pressure data of the water pump with a preset water supply pressure threshold, wherein the water supply pressure threshold includes a preset first water supply pressure threshold and a preset second water supply pressure threshold, and the preset first water supply pressure threshold is less than the preset second water supply pressure threshold; If the water supply pressure data of the water pump is less than the preset first water supply pressure threshold, it corresponds to the valley water supply pressure level, and the mean value and corresponding water supply time of the water supply pressure data of the water pump are the valley water supply pressure and valley water supply time corresponding to the valley water supply pressure level respectively; If the water supply pressure data of the water pump is greater than or equal to the preset first water supply pressure threshold, and less than the preset second water supply pressure threshold, then it corresponds to the flat-peak water supply pressure level, and the mean value and corresponding water supply time of the water pump water supply pressure data are the flat-peak water supply pressure and the flat-peak water supply time corresponding to the flat-peak water supply pressure level respectively; If the water pump water supply pressure data is greater than or equal to the preset second water supply pressure threshold, it corresponds to the peak water supply pressure level, and the mean value of the water pump water supply pressure data and the corresponding water supply time are the peak water supply pressure and peak water supply time corresponding to the peak water supply pressure level, respectively.

[0042] It should be noted that in order to more accurately control the water pump pressure to implement water supply, first, based on the pressure sensors arranged at the water pump outlet and the user's home entrance, multiple historical water supply data including water supply time data and corresponding water pump water supply pressure data and user node water supply pressure data within a preset time period are obtained. In this embodiment, the preset time period is set to 1 day, and the pressure data is obtained every 5 minutes. The multiple water pump water supply pressure data obtained are respectively compared with the preset water supply pressure threshold. The preset water supply pressure threshold includes a preset first water supply pressure threshold and a preset second water supply pressure threshold. In this embodiment, the preset first water supply pressure threshold is set to 0.3MPa, and the preset second water supply pressure threshold is set to 0.4MPa. If the water If the pump water supply pressure data is less than the preset first water supply pressure threshold, it corresponds to the valley water supply pressure level. By performing threshold comparison on multiple water pump water supply pressure data and the corresponding water supply times, multiple valley water supply pressures and corresponding valley water supply times can be obtained. For example, multiple water pump water supply pressure data that are continuously less than the preset first water supply pressure threshold, the earliest corresponding time is 22:30 and the latest time is 07:30. The average of all the water pump water supply pressure data obtained is 0.26MPa, then 0.26MPa is the valley water supply pressure, and 22:30-07:30 is the valley water supply time; similarly, multiple flat peak water supply pressures and corresponding flat peak water supply times and multiple peak water supply pressures and corresponding peak water supply times can be obtained.

[0043] According to an embodiment of the present invention, the processing according to the user node water supply pressure data and the water supply pressure corresponding to the water supply pressure level to obtain the pipeline pressure loss value corresponding to the water supply pressure level includes: According to the valley water supply time, flat peak water supply time and peak water supply time, the corresponding user node water supply pressure data are averaged and calculated to obtain the valley actual supply pressure, flat peak actual supply pressure and peak actual supply pressure on the user side corresponding to the valley water supply time, flat peak water supply time and peak water supply time; The valley actual supply pressure, flat peak actual supply pressure and peak actual supply pressure on the user side are processed with the valley water supply pressure, flat peak water supply pressure and peak water supply pressure respectively to obtain the valley pipeline pressure loss value, flat peak pipeline pressure loss value and peak pipeline pressure loss value corresponding to the valley water supply time, flat peak water supply time and peak water supply time.

[0044] It should be noted that, during the implementation of water supply, pipeline pressure loss values ​​may not be the same for different pressures and different pipeline layouts. In order to accurately obtain pipeline pressure loss values ​​corresponding to different situations, firstly, the water supply pressure data of multiple user nodes corresponding to the obtained valley water supply time, flat peak water supply time and peak water supply time are averaged respectively to obtain the valley actual supply pressure, flat peak actual supply pressure and peak actual supply pressure on the user side corresponding to the valley water supply time, flat peak water supply time and peak water supply time, and then process them with the valley water supply pressure, flat peak water supply pressure and peak water supply pressure to obtain the valley pipeline pressure loss value, flat peak pipeline pressure loss value and peak pipeline pressure loss value corresponding to the valley water supply time, flat peak water supply time and peak water supply time; The calculation formula for the valley pipeline pressure loss value is: ; in, is the trough pipeline pressure loss value, For low water supply pressure, Provides pressure for the low-peak period on the user side; The calculation formula for the flat peak pipeline pressure loss value is: ; in, is the peak pipeline pressure loss value, Peak water supply pressure, The actual supply pressure for the user side during peak hours; The peak pipeline pressure loss value calculation formula is: ; in, is the peak pipeline pressure loss value, is the peak water supply pressure, To meet the peak supply pressure on the user side.

[0045] According to an embodiment of the present invention, the real-time water supply time point data is obtained, and the real-time water supply time point data is processed in combination with the water supply time corresponding to the water supply pressure level, the water supply pressure level and the corresponding water supply pressure and pipeline pressure loss value are obtained and processed, and the real-time water supply demand pressure of the water pump is obtained, including the valley water supply demand pressure, the flat peak water supply demand pressure and the peak water supply demand pressure, including: Obtain real-time water supply time point data, and compare the real-time water supply time point data with the water supply time corresponding to the water supply pressure level; If the real-time water supply time point is the low-peak water supply time, then the low-peak water supply pressure and the corresponding pipeline pressure loss value are summed and calculated to obtain the low-peak water supply demand pressure of the water pump; If the real-time water supply time point is the flat-peak water supply time, then the flat-peak water supply pressure and the corresponding pipeline pressure loss value are summed and calculated to obtain the flat-peak water supply demand pressure of the water pump corresponding to the flat-peak water supply pressure level; If the real-time water supply time point is the peak water supply time, then corresponding to the peak water supply pressure level, the peak water supply pressure and the corresponding pipeline pressure loss value are summed and calculated to obtain the peak water supply demand pressure of the water pump.

[0046] It should be noted that in order to obtain the water supply pressure of the pump suitable for the current time, the real-time water supply time point data is first obtained, and the real-time water supply time point data is determined to belong to the valley water supply time, the flat peak water supply time or the peak water supply time according to the water supply time corresponding to the water supply pressure level. For example, if the real-time water supply time point is 06:00, which is the valley water supply time, the valley water supply pressure and the pipeline pressure loss value corresponding to the valley water supply pressure level are summed and calculated to obtain the valley water supply demand pressure of the water pump. For example, the valley water supply pressure is 0.26MPa and the pipeline pressure loss value is 0.02MPa, then 0.26+0.02=0.28MPa is the valley water supply demand pressure corresponding to the real-time water supply time point data; similarly, the flat peak water supply demand pressure and the peak water supply demand pressure corresponding to the real-time water supply time point data can be obtained.

[0047] According to an embodiment of the present invention, the water supply pressure control of the water pump according to the real-time demand implements water supply and obtains the real-time water supply pressure data of the user node, and processes the real-time water supply pressure data of the user node to obtain the real-time water supply evaluation index, including: Control the water pump to supply water according to the water supply pressure in real time; Obtain real-time water supply pressure data of user nodes, and extract peak pressure data and valley pressure data; Calculate the node pressure variance based on the real-time water supply pressure data of the user node; The peak pressure data, the valley pressure data and the node pressure variance are input into a preset real-time water supply evaluation model for processing to obtain a real-time water supply evaluation index.

[0048] It should be noted that after obtaining the real-time demand water supply pressure corresponding to the real-time water supply time point, the water pump is controlled according to the pressure to implement water supply, and the real-time water supply pressure data of the user node is obtained. First, the peak pressure data and the valley pressure data are extracted, and then the node pressure variance is obtained based on the obtained real-time water supply pressure data of multiple user nodes. For example, the obtained real-time water supply pressure data of the user node are 0.25, 0.27, 0.28, 0.28, 0.26, and 0.25MPa, the extracted peak pressure data is 0.28MPa, the valley pressure data is 0.25MPa, and the average value is 0.265MPa, [(0.26-0.265) 2+ (0.26-0.265) 2 + (0.26-0.265) 2 + (0.26-0.265) 2 + (0.26-0.265) 2 + (0.26-0.265) 2 ] / 6=0.000158 is the node pressure variance. The peak pressure data, valley pressure data and node pressure variance are input into the preset real-time water supply assessment model to obtain the real-time water supply assessment index. The real-time water supply evaluation index calculation formula is: ; in, For real-time water supply assessment index, , , They are peak pressure data, valley pressure data, and node pressure variance, , , It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the constant pressure water supply control platform).

[0049] According to an embodiment of the present invention, the real-time water supply evaluation index is compared with a preset water supply evaluation threshold, and the water supply mode is adjusted according to the comparison result, including: Comparing the real-time water supply assessment index with a preset water supply assessment threshold, wherein the preset water supply assessment threshold includes a first preset water supply assessment threshold, a second preset water supply assessment threshold, and a third preset water supply assessment threshold, and the first preset water supply assessment threshold is less than the second preset water supply assessment threshold, and the second preset water supply assessment threshold is less than the third preset water supply assessment threshold; If it is less than the first preset water supply assessment threshold, the auxiliary water pump is started synchronously to supply water; If it is greater than or equal to the first preset water supply assessment threshold and less than the second preset water supply assessment threshold, the auxiliary water pump is not turned on and the main water pump speed is automatically adjusted; If it is greater than or equal to the second preset water supply assessment threshold and less than the third preset water supply assessment threshold, no adjustment is made; If it is greater than or equal to the third preset water supply assessment threshold, the main water pump is turned off and the auxiliary water pump is turned on.

[0050] It should be noted that the obtained real-time water supply evaluation index is compared with the preset water supply evaluation threshold. In this embodiment, the preset water supply evaluation threshold is set to (0, 0.5), [0.5, 0.65), [0.65, 0.85), and [0.85, 1], which respectively correspond to synchronously starting the auxiliary water pump to supply water, not starting the auxiliary water pump, automatically adjusting the speed of the main water pump, not making any adjustment, shutting down the main water pump, and starting the auxiliary water pump; for example, the real-time water supply evaluation index obtained is 0.4, indicating that the water supply effect is poor, then the auxiliary water pump is started synchronously to supply water.

[0051] According to an embodiment of the present invention, if the water supply value is greater than or equal to the first preset water supply assessment threshold and less than the second preset water supply assessment threshold, the auxiliary water pump is not turned on and the main water pump speed is automatically adjusted, and then the following further includes: According to the real-time water supply evaluation index, a preset water supply evaluation index and water pump speed relationship mapping table is queried to obtain the required speed of the main water pump; The water supply of the main water pump is controlled according to the required speed of the main water pump.

[0052] It should be noted that in order to achieve precise control of the water pump, the preset water supply evaluation index and water pump speed relationship mapping table is queried according to the real-time water supply evaluation index obtained to obtain the main water pump demand speed. The preset water supply evaluation index and water pump speed relationship mapping table is generated after obtaining the water supply evaluation index of a large number of historical samples and the corresponding water pump speed analysis. After determining the main water pump demand speed, the main water pump water supply is controlled.

[0053] According to an embodiment of the present invention, the method of controlling the main water pump to supply water according to the required speed of the main water pump further includes: Obtain real-time water supply characteristic data of the main water pump, including flow data, head data and input power; Processing is performed according to the flow data, head data and input power to obtain the real-time water supply efficiency of the main water pump; Comparing the real-time water supply efficiency of the main water pump with a preset main water supply efficiency threshold; If it is less than the preset main water pump water supply efficiency threshold, an inefficient operation warning will be output; If it is greater than or equal to the main water pump water supply efficiency threshold, no processing will be performed.

[0054] It should be noted that the water pump is the main energy-consuming equipment in the standardized pump room. In order to meet the water supply demand and reduce energy consumption at the same time, the efficiency of the water pump should be guaranteed. The main water pump water supply should be controlled according to the determined main water pump demand speed, and the real-time water supply characteristic data of the main water pump including flow data, head data and input power should be obtained. The flow data, head data and input power should be input into the preset water pump water supply efficiency evaluation model for processing to obtain the real-time water supply efficiency of the main water pump. The calculation formula for the real-time efficiency of the main water pump water supply in the water pump water supply efficiency evaluation model is: ; in, Real-time efficiency of water supply to the main water pump, , , They are flow data, head data and input power respectively. is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the constant pressure water supply control platform); The obtained real-time water supply efficiency of the main water pump is compared with the preset main water supply efficiency threshold. In this embodiment, the main water supply efficiency threshold is set to (0, 0.8), [0.8, 1], and an inefficient operation warning is output correspondingly without adjustment. For example, if the obtained real-time water supply efficiency of the main water pump is 0.7, it means that the water pump efficiency is low, and an inefficient operation warning is output. If the obtained real-time water supply efficiency of the main water pump is 0.85, it means that the water pump efficiency is high, and no adjustment is made.

[0055] It is worth mentioning that according to an embodiment of the present invention, it also includes: Get the real-time pressure value of the city water at the preset node in front of the water pump; Processing the real-time city water pressure value and the preset city water standard pressure value to obtain the city water pressure deviation rate; Comparing the city water pressure deviation rate with a preset city water pressure deviation threshold, wherein the preset city water pressure deviation threshold includes a first preset city water pressure deviation threshold and a second preset city water pressure deviation threshold, and the first preset city water pressure deviation threshold is less than the second preset city water pressure deviation threshold; If it is less than the first preset city water pressure deviation threshold, the water pump is controlled to be turned off; If it is greater than or equal to the first preset city water pressure deviation threshold and less than the second preset city water pressure deviation threshold, a pressure loss warning is output; If it is greater than the second preset city water pressure deviation threshold, no adjustment is made.

[0056] It should be noted that during the water supply process, if there is a leakage, municipal water outage or other problems, the water pump cannot respond in time, which may cause damage to the water pump. Therefore, the real-time pressure value of the municipal water at the preset node in front of the water pump is first obtained, and processed with the preset municipal water standard pressure value to obtain the municipal water pressure deviation rate. For example, the real-time pressure value of the municipal water is 0.38MPa, and the preset municipal water standard pressure value is 0.4MPa, then (0.4-0.38) / 0.4=0.05 is the municipal water pressure deviation rate; the obtained municipal water pressure deviation rate is compared with the preset municipal water pressure deviation threshold. In this embodiment, the preset municipal water pressure deviation threshold is set to (0, 0.1), [0.1, 0.2), [0.2, 1], corresponding to no adjustment, output pressure loss warning, and control of water pump shutdown; for example, if the obtained municipal water pressure deviation rate is 0.05, it means that the deviation is not large, and no adjustment is made.
