[0002] In a water supply system, maintaining stable water pressure is crucial for ensuring water supply quality and the normal operation of equipment. Traditional water pump pressure stabilization control methods usually rely on centralized control systems, which have problems such as large data transmission delays, high requirements for network environments, and limited processing capabilities. When water pressure fluctuates, it is difficult for traditional systems to respond quickly and accurately in a timely manner, resulting in unstable water pressure and affecting user experience or the continuity of industrial production. With the development of Internet of Things technology, the amount of data generated by water pump systems is increasing continuously, and traditional methods face great challenges in processing and analyzing this large amount of data.

[0021] Please refer to Figure 1 , Figure 1 is a flowchart of a water pump voltage stabilization control method based on edge computing in some embodiments of the present application. The water pump voltage stabilization control method based on edge computing is used in edge devices. The water pump voltage stabilization control method based on edge computing includes the following steps: S11. Obtain historical water supply data of a preset number in a preset time period of the water supply system, and obtain the water supply stage according to the processing of the historical water supply data; S12. Establish a stage water supply standard database according to the water supply stage in combination with the historical water supply data; S13. Obtain real-time water supply time data, real-time water supply demand data, and real-time water supply pressure data at a preset number of key positions, and obtain effective real-time water supply pressure data according to the processing of the real-time water supply pressure data; S14. Query the stage water supply standard database according to the real-time water supply time data to obtain the corresponding real-time stage water supply standard data, and obtain the water supply state evaluation threshold according to the processing of the real-time stage water supply standard data; S15. Compare the real-time water supply demand data with the water supply state evaluation threshold to obtain the water supply state; S16. Obtain water supply pressure deviation data according to the real-time stage water supply standard data, real-time water supply demand data, and effective real-time water supply pressure data; S17. Regulate the water pump pressure according to the water supply state and the water supply pressure deviation data.

[0022] It should be noted that historical water supply data are the parameters of the operation of the water supply system in the past. Referring to the historical water supply data can better maintain the stable operation of the system. After obtaining the historical water supply data of the preset quantity within the preset time period of the water supply system, the corresponding water supply standard data for the historical stage can be obtained through calculation, statistics, and classification, and then a stage water supply standard database can be generated. The user terminals of the water supply system are generally relatively fixed, and the water supply demand does not change much compared with the historical water supply demand in the same period. Therefore, it can be used as the basis for real-time water supply. Obtain the real-time water supply time data, the real-time water supply demand data corresponding to the real-time water supply time data, and the real-time water supply pressure data at a plurality of preset key positions. Calculate the average value of the real-time water supply pressure data to obtain the effective real-time water supply pressure data. Query the stage water supply standard database according to the real-time water supply time data to obtain the real-time stage water supply standard data corresponding to the real-time water supply time data. Then, obtain the water supply status evaluation threshold after processing according to the real-time stage water supply standard data. Compare the real-time water supply demand data with the water supply status evaluation threshold to obtain the real-time water supply status and determine whether the water supply demand can be met. Process the real-time stage water supply standard data, the real-time water supply demand data, and the effective real-time water supply pressure data to obtain the water supply pressure deviation data. Finally, adjust the pump pressure according to the water supply status and the water supply pressure deviation data.

[0023] Please refer to Figure 2 , Figure 2 is the flowchart of obtaining the water supply stage of the pump voltage stabilization control method based on edge computing in some embodiments of the present application. According to the embodiments of the present invention, the obtaining of the historical water supply data of the preset quantity within the preset time period of the water supply system and the obtaining of the water supply stage according to the historical water supply data specifically include: S21. Obtain the historical water supply data of the preset quantity within the preset time period of the water supply system, including historical water supply time data, the corresponding historical water supply demand data, and historical water supply pressure data; S22. Calculate the historical water supply demand average value and the historical water supply demand standard deviation according to the historical water supply demand data; S23. Process the historical water supply demand average value and the historical water supply demand standard deviation to obtain the water supply stage evaluation threshold data, including the lower bound of the water supply peak time and the upper bound of the water supply valley time; S24. Compare the historical water supply demand data with the lower bound of the water supply peak time and the upper bound of the water supply valley time for threshold comparison, and obtain the water supply stage according to the threshold comparison result, including the water supply peak time, the water supply valley time, or the water supply normal time.

[0024] It should be noted that the water supply situation of the water supply system changes with the water consumption demands of end-users. However, due to the relative fixity of end-users, the water supply situation follows certain patterns. To better adjust the water supply according to the demands of end-users, historical water supply data for a preset period and a preset quantity are obtained. The preset period can be set according to user needs, and the preset quantity can also be customized by the user as required. After determining the preset quantity, data can be obtained at fixed intervals. When sampling, not only the historical water supply time data needs to be determined, but also the corresponding historical water supply demand data and historical water supply pressure data; after averaging the historical water supply demand data, the average value of historical water supply demand can be obtained, and then the standard deviation of historical water supply demand is calculated in combination with the average value of historical water supply demand; the water supply demand data is a variable data, so there will be different water supply stages during the water supply process, such as peak hours or valley hours. The average value of historical water supply demand is just a single data, and a data interval needs to be set to reflect the water supply stage. Therefore, it is necessary to obtain the threshold data for evaluating the water supply stage. The calculation formula for the lower bound of the water supply peak is: ; Wherein, is the lower bound of the water supply peak, is the average value of historical water supply demand, is the standard deviation of historical water supply demand, , are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset water pump voltage stabilization control platform based on edge computing); The calculation formula for the upper bound of the water supply valley is: ; Wherein, is the upper bound of the water supply valley, is the average value of historical water supply demand, is the standard deviation of historical water supply demand, , are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset water pump voltage stabilization control platform based on edge computing); By comparing the historical water supply demand data with the lower bound of the water supply peak and the upper bound of the water supply valley, the water supply peak hour, water supply valley hour, or normal water supply hour can be obtained.

[0025] According to an embodiment of the present invention, the step of comparing the historical water supply demand data with the lower bound of the water supply peak and the upper bound of the water supply valley, and obtaining the water supply stage according to the threshold comparison result specifically includes: If the historical water supply demand data is greater than or equal to the lower bound of the water supply peak, the historical water supply time data corresponding to the historical water supply demand data is the water supply peak hour; If the historical water supply demand data is less than the lower bound of the peak water supply time and greater than or equal to the upper bound of the valley water supply time, the historical water supply time data corresponding to the historical water supply demand data is the normal water supply time; If the historical water supply demand data is less than the upper bound of the valley water supply time, the historical water supply time data corresponding to the historical water supply demand data is the normal water supply time.

[0026] It should be noted that by comparing the historical water supply demand data with the lower bound of the peak water supply time and the upper bound of the valley water supply time, the water supply stage of the historical water supply time data corresponding to the historical water supply demand data participating in the threshold comparison can be obtained.

[0027] Please refer to Figure 3 , Figure 3 is the flowchart of establishing the stage water supply standard database for the water pump voltage stabilization control method based on edge computing provided by the embodiment of the present application. According to the embodiment of the present invention, the establishment of the stage water supply standard database according to the water supply stage and the historical water supply data specifically includes: S31. Classify the peak water supply time, valley water supply time or normal water supply time to obtain the water supply state time periods respectively, including the peak water supply time period, valley water supply time period or normal water supply time period; S32. Calculate the mean values according to the historical water supply time data, the corresponding historical water supply demand data, historical water supply pressure data, combined with the peak water supply time period, valley water supply time period or normal water supply time period, to obtain the historical stage water supply standard data corresponding to the water supply state time periods respectively, including historical stage water supply demand standard data and historical stage water supply pressure standard data; S33. Establish a stage water supply standard database with the water supply state time periods and the corresponding historical stage water supply demand standard data and historical stage water supply pressure standard data.

[0028] It should be noted that the water supply stage corresponding to a single time point can be obtained through threshold comparison. After obtaining the water supply stages of multiple time points, the water supply state time periods, including the peak water supply time period, valley water supply time period or normal water supply time period, can be analyzed by preset classification and statistical methods for the same category and time - close times. The peak water supply time period means that the water supply is at the peak value within this time period; there can be multiple peak water supply time periods, valley water supply time periods or normal water supply time periods in a day or a cycle; the average value within the water supply state time period can better reflect the water supply parameters. First, judge which ones belong to this time period according to the historical water supply time data, and then calculate the average values of the historical water supply demand data and historical water supply pressure data within this time period respectively to obtain the historical stage water supply demand standard data and historical stage water supply pressure standard data. The established stage water supply standard database includes the water supply state time periods and the corresponding historical stage water supply demand standard data and historical stage water supply pressure standard data.

[0029] Please refer toFigure 4 , Figure 4 is a flowchart of effective real - time water supply pressure data for the water pump voltage - stabilizing control method based on edge computing provided by an embodiment of the present application. According to an embodiment of the present invention, the method for obtaining real - time water supply time data, real - time water supply demand data, and real - time water supply pressure data at a plurality of preset key positions, and processing the real - time water supply pressure data to obtain effective real - time water supply pressure data specifically includes: S41. Obtain real - time water supply time data, real - time water supply demand data corresponding to the real - time water supply time data, and real - time water supply pressure data at a plurality of preset key positions; S42. Calculate the average value according to the real - time water supply pressure data to obtain effective real - time water supply pressure data.

[0030] It should be noted that in the water supply system, due to different pipeline layout situations, real - time water supply pressure data at multiple key positions need to be obtained. In order to more comprehensively and effectively reflect the real - time water supply pressure, the effective real - time water supply pressure data is obtained by calculating the average value of multiple real - time water supply pressure data.

[0031] According to an embodiment of the present invention, the method for querying the stage water supply standard database according to the real - time water supply time data to obtain the corresponding real - time stage water supply standard data, and processing the real - time stage water supply standard data to obtain the water supply status evaluation threshold specifically includes: Query the stage water supply standard database according to the real - time water supply time data to obtain the corresponding historical stage water supply demand standard data, and record the historical stage water supply demand standard data corresponding to the real - time water supply time data as the real - time stage demand standard data; Multiply the real - time stage demand water supply standard data by a preset upper limit coefficient to obtain the upper limit threshold for water supply status evaluation, and multiply the real - time stage water supply standard data by a preset lower limit coefficient to obtain the lower limit threshold for water supply status evaluation.

[0032] It should be noted that after obtaining the real - time water supply time data, the historical stage water supply demand standard data corresponding to the same historical time can be queried from the stage water supply standard database and used as the current water supply data, denoted as the real - time stage demand standard data. When using the real - time stage demand standard data as the water supply output, it can meet the real - time water supply demand data within a certain floating range. Therefore, multiply the real - time stage demand water supply standard data by a preset upper limit coefficient to obtain the upper limit threshold for water supply status evaluation, and multiply the real - time stage water supply standard data by a preset lower limit coefficient to obtain the lower limit threshold for water supply status evaluation; the preset upper limit coefficient and the preset lower limit coefficient are obtained by training based on the historical data of the water supply system, and users can adjust and set them according to actual needs.

[0033] According to an embodiment of the present invention, the method for comparing the real - time water supply demand data with the water supply status evaluation threshold to obtain the water supply status specifically includes: Compare the real-time water supply demand data with the upper threshold and lower threshold for evaluating the water supply status to obtain the water supply status, including over-water supply status, stable water supply status, or insufficient water supply status; If the real-time water supply demand data is greater than the upper threshold for evaluating the water supply status, the water supply status is insufficient water supply status; If the real-time water supply demand data is greater than the lower threshold for evaluating the water supply status and less than or equal to the upper threshold for evaluating the water supply status, the water supply status is stable water supply status; If the real-time water supply demand data is less than or equal to the lower threshold for evaluating the water supply status, the water supply status is over-water supply status.

[0034] It should be noted that when the real-time water supply demand data is greater than the upper threshold for evaluating the water supply status, the current water supply can no longer meet the real-time water supply demand data, which is the insufficient water supply status; the stable water supply status indicates that the real-time water supply demand can be met; the over-water supply status means that the water supply is excessive in this state.

[0035] According to the embodiment of the present invention, the processing of obtaining the water supply pressure deviation data based on the real-time stage water supply standard data, real-time water supply demand data, and effective real-time water supply pressure data specifically includes: Input the stage demand standard data, stage pressure standard data, real-time water supply demand data, and effective real-time water supply pressure data into a preset water supply pressure deviation evaluation model for processing to obtain the water supply pressure deviation data.

[0036] It should be noted that the water supply pressure deviation evaluation model is a model obtained by training with a large amount of historical data, and the water supply pressure deviation data can be calculated through this model; The calculation formula for the water supply pressure deviation data in the water supply pressure deviation evaluation model is: ; Wherein, is the water supply pressure deviation data, , are the stage demand standard data and stage pressure standard data respectively, , are the real-time water supply demand data and effective real-time water supply pressure data respectively, , , , are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset water pump voltage stabilizing control platform based on edge computing).

[0037] According to the embodiment of the present invention, the regulation of the water pump pressure based on the water supply status and water supply pressure deviation data specifically includes: If the water supply status is an over - water - supply status, the effective real - time water supply pressure data is reduced by the water supply pressure deviation data; If the water supply status is a stable water supply status, the effective real - time water supply pressure data remains unchanged; If the water supply status is an under - water - supply status, the effective real - time water supply pressure data is increased by the water supply pressure deviation data.

[0038] It should be noted that when the water supply status is an over - water - supply status, it means that the water supply is excessive, and the water supply pressure can be appropriately reduced. Therefore, the effective real - time water supply pressure data is subtracted by the water supply pressure deviation data. When the water supply status is an under - water - supply status, it means that the water supply is insufficient, and the water supply pressure needs to be increased. On the basis of the effective real - time water supply pressure data, the water supply pressure deviation data is added.

[0039] It is worth mentioning that it also includes: Obtain the water supply pressure deviation data of a preset time period according to a preset time interval; Calculate the average value of the water supply pressure deviation and the variance of the water supply pressure deviation according to the water supply pressure deviation data; Process the average value of the water supply pressure deviation and the variance of the water supply pressure deviation through a preset water supply trend status evaluation model to obtain a water supply trend index; The calculation formula of the water supply trend index in the water supply trend status evaluation model is: ; Wherein, is the water supply trend index, and are respectively the average value of the water supply pressure deviation and the variance of the water supply pressure deviation, and and are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset water pump voltage - stabilizing control platform based on edge computing).

[0040] It should be noted that during the water supply process, in order to ensure meeting the water use requirements of users or ensuring the normal operation of the water supply, it is necessary to judge the water supply pressure deviation data. If the water supply pressure deviation data suddenly increases or suddenly decreases, it is not appropriate, indicating an abnormal situation. Therefore, in order to better predict the water supply situation, the average value of the water supply pressure deviation and the variance of the water supply pressure deviation are calculated. The water supply trend status evaluation model is obtained through training with a large amount of historical data.

[0041] It is worth mentioning that it also includes: Compare the water supply trend index with a preset water supply trend status threshold to obtain a water supply trend status, including a stable trend and an abnormal trend; Extract a first threshold and a second threshold according to the water supply trend status threshold, and the first threshold is greater than the second threshold; Compare the water supply trend index with the first threshold and the second threshold; If the water supply trend index is greater than the first threshold or less than the second threshold, the water supply trend status is an abnormal trend; If the water supply trend index is greater than or equal to the second threshold and less than or equal to the first threshold, the water supply trend status is a stable trend.

[0042] It should be noted that when the water supply trend status is a stable trend, it indicates that the change in water supply demand is small; when the water supply trend status is an abnormal trend, it indicates that there is an abnormality in the water supply system, and there may be a sudden large increase in water supply demand, or pipeline damage, or abnormal operation. Once an abnormal trend is determined, corresponding measures can be taken in a timely manner.

[0043] The present invention also discloses a water pump pressure stabilization control gateway based on edge computing. A program of a water pump pressure stabilization control method based on edge computing is stored in the gateway. When the program of the water pump pressure stabilization control method based on edge computing is executed by the processor, the following steps are implemented: Obtain historical water supply data of a preset number in a preset time period of the water supply system, and obtain a water supply stage according to the processing of the historical water supply data; Establish a stage water supply standard database according to the water supply stage and historical water supply data; Obtain real-time water supply time data, real-time water supply demand data, and real-time water supply pressure data at a preset number of key positions, and obtain effective real-time water supply pressure data according to the processing of the real-time water supply pressure data; Query the stage water supply standard database according to the real-time water supply time data to obtain corresponding real-time stage water supply standard data, and obtain a water supply status evaluation threshold according to the processing of the real-time stage water supply standard data; Compare the real-time water supply demand data with the water supply status evaluation threshold to obtain a water supply status; Obtain water supply pressure deviation data according to the real-time stage water supply standard data, real-time water supply demand data, and effective real-time water supply pressure data; Regulate the water pump pressure according to the water supply status and the water supply pressure deviation data.

[0044] It should be noted that historical water supply data are the parameters of the operation of the water supply system in the past. Referring to the historical water supply data can better maintain the stable operation of the system. After obtaining the historical water supply data of a preset quantity within a preset time period of the water supply system, the corresponding water supply standard data for the historical stage can be obtained through calculation, statistics, and classification, and then a stage water supply standard database can be generated. The user terminals of the water supply system are generally relatively fixed, and the water supply demand changes little compared with the historical water supply demand in the same period. Therefore, it can be used as the basis for real-time water supply. Obtain the real-time water supply time data, the real-time water supply demand data corresponding to the real-time water supply time data, and the real-time water supply pressure data at a plurality of preset key positions. Calculate the average value of the real-time water supply pressure data to obtain the effective real-time water supply pressure data. Query the stage water supply standard database according to the real-time water supply time data to obtain the real-time stage water supply standard data corresponding to the real-time water supply time data. Then, obtain the water supply status evaluation threshold after processing according to the real-time stage water supply standard data. Compare the real-time water supply demand data with the water supply status evaluation threshold to obtain the real-time water supply status and determine whether the water supply demand can be met. Process the real-time stage water supply standard data, the real-time water supply demand data, and the effective real-time water supply pressure data to obtain the water supply pressure deviation data. Finally, adjust the water pump pressure according to the water supply status and the water supply pressure deviation data.

[0045] According to an embodiment of the present invention, the obtaining of the historical water supply data of a preset quantity within a preset time period of the water supply system and the obtaining of the water supply stage according to the historical water supply data specifically include: Obtaining the historical water supply data of a preset quantity within a preset time period of the water supply system, including historical water supply time data, as well as the corresponding historical water supply demand data and historical water supply pressure data; Calculating the average value of the historical water supply demand and the standard deviation of the historical water supply demand according to the historical water supply demand data; Processing the average value of the historical water supply demand and the standard deviation of the historical water supply demand to obtain the water supply stage evaluation threshold data, including the lower bound of the water supply peak time and the upper bound of the water supply valley time; Comparing the historical water supply demand data with the lower bound of the water supply peak time and the upper bound of the water supply valley time, and obtaining the water supply stage according to the threshold comparison result, including the water supply peak time, the water supply valley time, or the normal water supply time.

[0046] It should be noted that the water supply situation of the water supply system changes with the water consumption demand of the end users. However, due to the relative fixity of the end users, the water supply situation follows certain rules. To better adjust the water supply according to the needs of the end users, historical water supply data for a preset period and a preset quantity are obtained. The preset period can be set according to user needs, and the preset quantity can also be customized by the user as needed. After determining the preset quantity, data can be obtained at fixed intervals. When sampling, not only the historical water supply time data needs to be determined, but also the historical water supply demand data and historical water supply pressure data corresponding to the historical water supply time data should be determined. After calculating the average value of the historical water supply demand data, the historical water supply demand average value can be obtained, and then the historical water supply demand standard deviation can be calculated in combination with the historical water supply demand average value. Since the water supply demand data is a variable data, there will be different water supply stages during the water supply process, such as peak hours or valley hours. The historical water supply demand average value is just a single data, and a data interval needs to be set to reflect the water supply stage. Therefore, it is necessary to obtain the water supply stage evaluation threshold data. The calculation formula for the lower bound of the water supply peak is: ; Wherein, is the lower bound of the water supply peak, is the historical water supply demand average value, is the historical water supply demand standard deviation, 、 are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset water pump voltage stabilization control platform based on edge computing); The calculation formula for the upper bound of the water supply valley is: ; Wherein, is the upper bound of the water supply valley, is the historical water supply demand average value, is the historical water supply demand standard deviation, 、 are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset water pump voltage stabilization control platform based on edge computing); By comparing the historical water supply demand data with the lower bound of the water supply peak and the upper bound of the water supply valley, the water supply peak time, water supply valley time or normal water supply time can be obtained.

[0047] According to an embodiment of the present invention, the step of comparing the historical water supply demand data with the lower bound of the water supply peak and the upper bound of the water supply valley and obtaining the water supply stage according to the threshold comparison result specifically includes: If the historical water supply demand data is greater than or equal to the lower bound of the water supply peak, the historical water supply time data corresponding to the historical water supply demand data is the water supply peak time; If the historical water supply demand data is less than the lower bound of the peak water supply time and greater than or equal to the upper bound of the valley water supply time, the historical water supply time data corresponding to the historical water supply demand data is the normal water supply time; If the historical water supply demand data is less than the upper bound of the valley water supply time, the historical water supply time data corresponding to the historical water supply demand data is the normal water supply time.

[0048] It should be noted that by comparing the historical water supply demand data with the lower bound of the peak water supply time and the upper bound of the valley water supply time, the water supply stage of the historical water supply time data corresponding to the historical water supply demand data participating in the threshold comparison can be obtained.

[0049] According to an embodiment of the present invention, establishing a stage water supply standard database according to the water supply stage in combination with historical water supply data specifically includes: Classify the peak water supply time, valley water supply time or normal water supply time to obtain water supply state time periods respectively, including peak water supply time periods, valley water supply time periods or normal water supply time periods; According to the historical water supply time data, the corresponding historical water supply demand data, historical water supply pressure data, in combination with the peak water supply time period, valley water supply time period or normal water supply time period, calculate the mean value to obtain historical stage water supply standard data corresponding to the water supply state time periods respectively, including historical stage water supply demand standard data and historical stage water supply pressure standard data; Establish a stage water supply standard database with the water supply state time periods and the corresponding historical stage water supply demand standard data and historical stage water supply pressure standard data.

[0050] It should be noted that through threshold comparison, the water supply stage corresponding to a single time point can be obtained. After obtaining the water supply stages of multiple time points, the time points of the same category and close in time can be analyzed through a preset classification and statistical method to obtain water supply state time periods, including peak water supply time periods, valley water supply time periods or normal water supply time periods. The peak water supply time period means that the water supply is at the peak value within this time period; there can be multiple peak water supply time periods, valley water supply time periods or normal water supply time periods in a day or a cycle; the average value within the water supply state time period can better reflect the water supply parameters. First, judge which ones belong to this time period according to the historical water supply time data, and then calculate the average value through the historical water supply demand data and historical water supply pressure data within this time period to obtain the historical stage water supply demand standard data and historical stage water supply pressure standard data. The established stage water supply standard database includes the water supply state time periods and the corresponding historical stage water supply demand standard data and historical stage water supply pressure standard data.

[0051] According to an embodiment of the present invention, obtaining real-time water supply time data, real-time water supply demand data and real-time water supply pressure data at a plurality of preset key positions, and processing the real-time water supply pressure data to obtain effective real-time water supply pressure data specifically includes: Obtain real - time water supply time data, real - time water supply demand data corresponding to the real - time water supply time data, and real - time water supply pressure data at a plurality of preset key positions; Calculate the average value based on the real - time water supply pressure data to obtain effective real - time water supply pressure data.

[0052] It should be noted that in the water supply system, due to different pipeline layouts, real - time water supply pressure data at a plurality of key positions need to be obtained. In order to more comprehensively and effectively reflect the real - time water supply pressure, the effective real - time water supply pressure data is obtained by calculating the average value of a plurality of real - time water supply pressure data.

[0053] According to an embodiment of the present invention, querying the stage water supply standard database according to the real - time water supply time data to obtain corresponding real - time stage water supply standard data, and processing according to the real - time stage water supply standard data to obtain a water supply status evaluation threshold, specifically includes: Query the stage water supply standard database according to the real - time water supply time data to obtain corresponding historical stage water supply demand standard data, and record the historical stage water supply demand standard data corresponding to the real - time water supply time data as real - time stage demand standard data; Multiply the real - time stage demand water supply standard data by a preset upper limit coefficient to obtain a water supply status evaluation upper limit threshold, and multiply the real - time stage water supply standard data by a preset lower limit coefficient to obtain a water supply status evaluation lower limit threshold.

[0054] It should be noted that after obtaining the real - time water supply time data, the historical stage water supply demand standard data corresponding to the same historical time can be queried from the stage water supply standard database and used as the current water supply data, denoted as real - time stage demand standard data. When using the real - time stage demand water supply standard data as the water supply output, it can meet the real - time water supply demand data within a certain floating range. Therefore, multiply the real - time stage demand water supply standard data by a preset upper limit coefficient to obtain a water supply status evaluation upper limit threshold, and multiply the real - time stage water supply standard data by a preset lower limit coefficient to obtain a water supply status evaluation lower limit threshold; the preset upper limit coefficient and the preset lower limit coefficient are obtained through training based on the historical data of the water supply system, and users can adjust and set them according to actual needs.

[0055] According to an embodiment of the present invention, comparing the real - time water supply demand data with the water supply status evaluation threshold to obtain the water supply status, specifically includes: Compare the real - time water supply demand data with the water supply status evaluation upper limit threshold and the water supply status evaluation lower limit threshold to obtain the water supply status, including an over - water - supply status, a stable water - supply status, or a water - supply shortage status; If the real - time water supply demand data is greater than the water supply status evaluation upper limit threshold, the water supply status is a water - supply shortage status; If the real-time water supply demand data is greater than the lower threshold value of the water supply status assessment and less than or equal to the upper threshold value of the water supply status assessment, the water supply status is a stable water supply status; If the real-time water supply demand data is less than or equal to the lower threshold value of the water supply status assessment, the water supply status is an excessive water supply status.

[0056] It should be noted that when the real-time water supply demand data is greater than the upper threshold value of the water supply status assessment, the current water supply can no longer meet the real-time water supply demand data, which is a water supply shortage status; the stable water supply status indicates that the real-time water supply demand can be met; the excessive water supply status means that there is too much water supply in this state.

[0057] According to an embodiment of the present invention, the processing of obtaining the water supply pressure deviation data based on the real-time stage water supply standard data, real-time water supply demand data, and effective real-time water supply pressure data specifically includes: Input the stage demand standard data, stage pressure standard data, real-time water supply demand data, and effective real-time water supply pressure data into a preset water supply pressure deviation evaluation model for processing to obtain the water supply pressure deviation data.

[0058] It should be noted that the water supply pressure deviation evaluation model is a model obtained through training with a large amount of historical data. Through this model, the water supply pressure deviation data can be calculated; The calculation formula for the water supply pressure deviation data in the water supply pressure deviation evaluation model is: ; Wherein, is the water supply pressure deviation data, , are the stage demand standard data and stage pressure standard data respectively, , are the real-time water supply demand data and effective real-time water supply pressure data respectively, , , , are preset characteristic coefficients (the characteristic coefficients are obtained by querying a preset water pump voltage stabilization control platform based on edge computing).

[0059] According to an embodiment of the present invention, the regulation of the water pump pressure based on the water supply status and water supply pressure deviation data specifically includes: If the water supply status is an excessive water supply status, the effective real-time water supply pressure data is reduced by the water supply pressure deviation data; If the water supply status is a stable water supply status, the effective real-time water supply pressure data remains unchanged; If the water supply status is a water supply shortage status, the effective real-time water supply pressure data is increased by the water supply pressure deviation data.

[0060] It should be noted that when the water supply state is in the over - water - supply state, it indicates that the water supply is excessive, and the water supply pressure can be appropriately reduced. Therefore, the effective real - time water supply pressure data is subtracted by the water supply pressure deviation data. When the water supply state is in the under - water - supply state, it indicates that the water supply is insufficient, and the water supply pressure needs to be increased. On the basis of the effective real - time water supply pressure data, the water supply pressure deviation data is added.

[0061] It is worth mentioning that it also includes: Obtaining water supply pressure deviation data for a preset time period according to a preset time interval; Calculating the average value of the water supply pressure deviation and the variance of the water supply pressure deviation based on the water supply pressure deviation data; Processing the average value of the water supply pressure deviation and the variance of the water supply pressure deviation through a preset water supply trend state evaluation model to obtain a water supply trend index; The calculation formula for the water supply trend index in the water supply trend state evaluation model is: ; Among them, is the water supply trend index, and are respectively the average value of the water supply pressure deviation and the variance of the water supply pressure deviation, and and are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset water pump voltage - stabilizing control platform based on edge computing).

[0062] It should be noted that during the water supply process, in order to ensure meeting the water use requirements of users or ensuring the normal operation of the water supply, it is necessary to judge the water supply pressure deviation data. If the water supply pressure deviation data suddenly increases or suddenly decreases, it is not appropriate, indicating an abnormal situation. Therefore, in order to better predict the water supply situation, the average value of the water supply pressure deviation and the variance of the water supply pressure deviation are calculated, and the water supply trend state evaluation model is obtained through training with a large amount of historical data.

[0063] It is worth mentioning that it also includes: Comparing the water supply trend index with a preset water supply trend state threshold to obtain a water supply trend state, including a stable trend and an abnormal trend; Extracting a first threshold and a second threshold according to the water supply trend state threshold, and the first threshold is greater than the second threshold; Comparing the water supply trend index with the first threshold and the second threshold; If the water supply trend index is greater than the first threshold or less than the second threshold, the water supply trend state is an abnormal trend; If the water supply trend index is greater than or equal to the second threshold and less than or equal to the first threshold, the water supply trend state is a stable trend.

[0064] It should be noted that when the water supply trend state is a stable trend, it indicates that the change in water supply demand is small; when the water supply trend state is an abnormal trend, it indicates that there is an abnormality in the water supply system, and there may be a sudden large increase in water supply demand, or pipeline damage, or abnormal operation. Once an abnormal trend is determined, corresponding measures can be taken in a timely manner.
