Description

Technical Field

[0001] The present application relates to the technical field of water pump regulation, and specifically relates to a water pump control method, device, equipment and storage medium. Background Art

[0002] At present, water pump systems are widely used in the water supply field to provide stable water pressure and water volume. In traditional water pump control methods, a fixed threshold is usually used to control the start and stop of the water pump. However, this control method cannot dynamically adjust the operating state of the water pump according to the actual water consumption demand, which may cause waste of water resources or affect users due to insufficient water supply. Summary of the Invention

[0003] The present application provides a water pump control method, device, equipment and storage medium, which are used to dynamically adjust the operating state of the water pump, and try to avoid the occurrence of situations that may cause waste of water resources or affect users due to insufficient water supply.

[0004] In a first aspect, the present application provides a water pump control method applied to a computer device. The method includes: determining the historical average water consumption of the target area in each time period according to the historical water consumption data of the target area; determining the lowest water pressure reference value and the highest water pressure reference value of the water pump in each time period of the target area according to the historical average water consumption of the target area in each time period; obtaining the first water consumption within a first preset duration before the current moment, and predicting the water consumption trend within a second preset duration after the current moment according to the first water consumption to obtain a prediction result; adjusting the lowest water pressure reference value and the highest water pressure reference value of the water pump in the time period corresponding to the second preset duration according to the prediction result.

[0005] By adopting the above technical solution, according to the historical water consumption data of the target area, the average water consumption of each time period in this area can be analyzed, which provides a basis for determining the reasonable water pressure reference value of the water pump at different times. Setting the reference value according to the actual water consumption characteristics can make the normal water supply of the water pump meet the demand and avoid long-term over-supply. Real-time monitoring of the current water consumption, and then predicting the water consumption change trend in the future according to the current water consumption data, can realize the prediction of future water consumption conditions, so that the system actively adjusts to the predicted water consumption demand. According to the prediction of the future water consumption trend, timely adjust the water pressure reference interval of the corresponding time period, so that the reference value can dynamically adapt to the demand change, and try to avoid the occurrence of situations that may cause waste of water resources or affect users due to insufficient water supply.

[0006] Optionally, determining the lowest reference value and the highest reference value of the water pressure of the water pump in each time period according to the historical average water consumption of the target area in each time period includes: drawing a water pressure curve graph of each time period according to the historical average water consumption of the target area in each time period; determining the lowest reference value and the highest reference value of the water pressure of the water pump in each time period according to the water pressure curve graph.

[0007] By adopting the above technical solution, this solution draws the corresponding water pressure curve graph for each time period according to the historical average water consumption of the target area at different times, and then determines the reference water pressure interval for each time period based on the position and shape of the curve. The method of determining the reference value by observing the change of the water pressure curve can intuitively reflect the water consumption characteristics at different times. When the position of the water pressure curve is relatively high, it indicates a large water consumption, and a relatively high highest reference value can be set at this time; while when the position of the curve is relatively low, it indicates a small water consumption in this time period, and a relatively low lowest reference value can be set. To sum up, this solution makes full use of the advantage of the water pressure curve graph to intuitively display the water consumption characteristics, making the determination of the reference water pressure value more accurate and reasonable, ensuring the basic water supply volume and achieving economic water-saving operation.

[0008] Optionally, predicting the water consumption trend within a second preset duration after the current moment according to the first water consumption to obtain a prediction result includes: combining the first water consumption and the historical average water consumption corresponding to the time period in which the second preset duration is located to predict the water consumption trend within a second preset duration after the current moment to obtain a prediction result.

[0009] By adopting the above technical solution, first obtain the first water consumption before the current moment, which represents the most recent water consumption situation. Then, compare it with the average water consumption level of the time period in which this first water consumption is located in the historical data. By comparing and analyzing the current real-time water consumption with the average water consumption in the same historical time period, the water consumption trend within the future preset duration can be predicted more accurately, that is, it can be judged whether the water consumption will be significantly higher or lower than the average level, providing a reliable basis for subsequent water consumption management decisions.

[0010] Optionally, combining the first water consumption and the historical average water consumption corresponding to the time period in which the second preset duration is located to predict the water consumption trend within a second preset duration after the current moment to obtain a prediction result includes: making a preliminary prediction of the water consumption trend within the second preset duration according to the first water consumption to obtain a preliminary prediction result; calculating the difference between the first water consumption and the historical average water consumption corresponding to the time period in which the second preset duration is located; adjusting the preliminary prediction result according to the difference to obtain the prediction result.

[0011] By adopting the above technical solution, this solution makes full use of the latest water usage situation reflected by the first water consumption to make a preliminary judgment on the water usage trend. For the preliminary prediction result, reference correction of historical data is carried out to avoid prediction deviation caused by relying only on current data. By calculating the difference between the real-time data and the historical average value, it can be judged whether the water consumption is higher or lower than the normal level, and the preliminary prediction is corrected accordingly. Since it combines real-time monitoring and historical analysis, compared with single data source prediction, this application can improve the prediction accuracy, make the result closer to the actual water usage situation, and provide a relatively reliable basis for subsequent water usage management decisions.

[0012] Optionally, adjusting the preliminary prediction result according to the difference to obtain the prediction result includes: if the difference is positive, increasing the preliminary prediction result by a value proportional to the difference; if the difference is negative, decreasing the preliminary prediction result by a value proportional to the difference; and obtaining the prediction result according to the increased or decreased value.

[0013] By adopting the above technical solution, if the recent water consumption exceeds the historical average level, the prediction result will increase; conversely, if the recent water consumption is lower than the historical average level, the prediction result will decrease, which can make the prediction result more in line with the actual situation and thus more effectively control the operation of the water pump.

[0014] Optionally, the method further includes: obtaining the water pressure at the current moment in the target area; if the water pressure is less than the preset minimum reference value or greater than the preset maximum reference value, sending an alarm message to the terminal device of the maintenance personnel so that the maintenance personnel can perform maintenance.

[0015] By adopting the above technical solution, the water pressure parameter during the operation of the water pump is monitored in real time. Once the water pressure is detected to be abnormal, that is, higher than the maximum reference value or lower than the minimum reference value, the system can immediately send an alarm message to notify the maintenance personnel. The reference value range of the alarm setting is the normal water pressure range determined according to historical data analysis. Therefore, if the water pressure exceeds this range, it can be judged as an abnormal situation. Obtaining the real-time water pressure and comparing it with the reference value can realize the real-time monitoring of the operation state of the water pump and ensure that the water pressure is within the normal range. Once an abnormality occurs, the maintenance personnel can be notified in the first time to enable them to rush to the scene for maintenance in time, avoiding the expansion of the fault or equipment damage, and improving the reliability and safety of the water pump system.

[0016] Optionally, after adjusting the minimum water pressure reference value and the maximum water pressure reference value of the water pump for the corresponding time period of the second preset duration according to the prediction result, it further includes: obtaining the feedback information of the user side; and optimizing the minimum water pressure reference value and / or the maximum water pressure reference value of the water pump in each time period of the target area according to the feedback information.

[0017] By adopting the above technical solution, after the system adjusts the reference water pressure value according to the prediction result, various feedback information from the user side can also be obtained. This feedback can help the system further determine whether the recent adjustment of the water use plan is scientific and reasonable and whether it causes a poor user water use experience. If the feedback shows that the user's water consumption is insufficient or the water pressure is unstable, the reference water pressure range can be appropriately increased. On the contrary, if the user reports an overabundance of water supply, the reference water pressure can be appropriately decreased. Through interaction and optimization with the user, the compliance of the water supply plan can be improved, enabling the reference water pressure value to meet both the user's needs and achieve water and energy conservation. In addition, user feedback can also be used as data for model training to continuously enhance the system's self-learning and optimization capabilities.

[0018] In a second aspect, the present application provides a water pump control device, which includes: a first determination module, a second determination module, a prediction module, and an adjustment module; wherein, the first determination module is configured to determine the historical average water consumption of the target area in each time period according to the historical water use data of the target area; the second determination module is configured to determine the lowest reference water pressure value and the highest reference water pressure value of the water pump in the target area in each time period according to the historical average water consumption of the target area in each time period; the prediction module is configured to obtain the first water consumption within a first preset duration before the current moment and predict the water use trend within a second preset duration after the current moment according to the first water consumption to obtain a prediction result; the adjustment module is configured to adjust the lowest reference water pressure value and the highest reference water pressure value of the water pump in the time period corresponding to the second preset duration according to the prediction result.

[0019] By adopting the above technical solution, according to the historical water use data of the target area, the average water consumption of each time period in this area can be analyzed, providing a basis for determining the reasonable reference water pressure value of the water pump at different times. Setting the reference value according to the actual water use characteristics can enable the normal water supply of the water pump to meet the demand and avoid long-term overabundant water supply. By monitoring the current water consumption in real time and predicting the water use change trend in the future based on the current water use data, it is possible to anticipate the future water use situation and enable the system to actively adjust to the predicted water use demand. According to the prediction of the future water use trend, the reference water pressure range of the corresponding time period is adjusted in a timely manner, enabling the reference value to dynamically adapt to the demand change and minimizing the occurrence of situations such as waste of water resources or impact on users due to insufficient water supply.

The memory is used to store instructions, the user interface and the network interface are used to communicate with other devices, and the processor is used to execute the instructions stored in the memory so that the electronic device executes a computer program of any one of the above water pump control methods.

[0021] In a fourth aspect, the present application provides a computer-readable storage medium, adopting the following technical solution: storing a computer program that can be loaded and executed by a processor to perform any of the above water pump control methods.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0030] In the description of the embodiments of the present application, words such as "exemplary", "for example" or "for illustration" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary", "for example" or "for illustration" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Specifically, the use of words such as "exemplary", "for example" or "for illustration" is intended to present relevant concepts in a specific manner.

[0031] Before proceeding with the description, the professional terms involved in this article are explained. Minimum water pressure reference value (L): It is used to determine whether the water pressure is too low. If the detected pressure value is lower than the minimum reference value, it indicates that the pressure is too low, and the water pump can be started to provide sufficient pressure. The setting of the minimum reference value can ensure that the pipeline system has sufficient water pressure to meet the requirements during normal operation; Maximum reference value (H): The maximum reference value is used to determine whether the water pressure is too high. If the detected pressure value is higher than the maximum reference value, it indicates that the pressure is too high, and the water pump needs to be stopped to avoid excessive pressure. The setting of the maximum reference value can protect the pipeline system from damage or failure caused by excessive pressure.

[0032] By adjusting the minimum reference value and the maximum reference value, the start and stop of the water pump can be controlled, or the rotation speed or power of the water pump can be adjusted to adapt to the requirements and operating conditions of the pipeline system. For example, in the low water flow mode, the minimum reference value can be reduced to adapt to the smaller water flow demand; while in the high water flow mode, the maximum reference value can be increased to avoid excessive pressure.

[0033] The setting of the minimum reference value and the maximum reference value needs to consider the characteristics of the pipeline system, the requirements of the equipment, and the safety of operation. Reasonable setting of the minimum reference value and the maximum reference value can ensure the normal operation of the system, prevent the water pump from starting and stopping frequently, and the occurrence of excessive pressure, thereby reducing the probability of water pump damage and improving the reliability and efficiency of the system.

[0034] Then, in the prior art, the setting of the minimum reference value and the maximum reference value of the water pump cannot be well applied to various places, and the setting of the minimum reference value and the maximum reference value will affect the start and stop frequency of the water pump. The setting of the minimum reference value and the maximum reference value has an impact on the stability and reliability of the system. If the minimum reference value and the maximum reference value are set unreasonably, it may lead to too low or too high water pressure, affecting the normal operation of the pipeline system. Too low water pressure may not meet the requirements, while too high water pressure may cause pipeline damage or leakage. Reasonable setting of the minimum reference value and the maximum reference value can keep the system within a safe and stable working range. If the minimum reference value is set too high or the maximum reference value is set too low, the water pump may start and stop frequently, which will increase the wear and energy consumption of the water pump and may reduce the stability of the system. Reasonable setting of the minimum reference value and the maximum reference value can reduce unnecessary starts and stops, improve the life of the water pump and the efficiency of the system.

[0035] This application reflects the water pressure by the amount of water used, and then adjusts the minimum reference value and the maximum reference value according to the too small water pressure.

[0036] This application discloses a water pump control method, as Figure 1 shown, this method includes S101 - S104.

[0037] S101. Determine the historical average water consumption of the target area in each time period according to the historical water consumption data of the target area.

[0038] In an example, obtain the historical water consumption data of the target area. The target area can be an industrial park or a residential community. Determining the historical average water consumption of the target area in each time period according to the historical water consumption data of the target area can more accurately judge the water demand in different time periods and provide a basis for subsequent setting of the water pressure reference value and pump control. Specifically, when implementing, it is first necessary to collect the water consumption data of the target area within a certain time range. For example, the hourly water consumption data of the target area in the past year can be selected. Then, according to the time period division, such as dividing it into working day daytime, night time, weekend time periods, etc., calculate the average water consumption in each time period. When calculating the average water consumption, abnormal data needs to be filtered out, and only valid historical water consumption data is retained to improve the accuracy of the average water consumption.

[0039] After obtaining the historical average water consumption of the target area in different time periods in this way, the lowest reference value and the highest reference value of the water pressure of the pump in each time period can be reasonably set according to the level of the average water consumption. Set the highest reference value higher in the high water consumption period and set the lowest reference value lower in the low water consumption period, so that the reference water pressure value can dynamically adapt to the water demand in different time periods. When performing intelligent control on the pump subsequently, it is also possible to judge whether the current water consumption is normal according to the historical average water consumption. If it is significantly higher, it may indicate a pipeline leak, and if it is lower, it may indicate a change in user water use behavior, both of which can be used as a basis for abnormal alarm.

[0040] In this way, by pre-analyzing the historical average water consumption in different time periods, the setting of the water pressure reference value and the pump control can be made more intelligent and economical, which can not only meet the different water demands in different time periods, but also discover abnormal situations and improve the water resource utilization efficiency.

[0041] S102. Determine the lowest reference value and the highest reference value of the water pressure of the pump in the target area in each time period according to the historical average water consumption of the target area in each time period.

[0042] In an example, determining the lowest reference value and the highest reference value of the water pressure of the pump in the target area in each time period according to the historical average water consumption of the target area in each time period can make the reference water pressure value dynamically adapt to the change of water demand in different time periods, ensuring both the reliability of water supply and the economic efficiency of operation.

[0043] The specific implementation method includes, first, according to the historical average water consumption data of the target area at different time periods, combined with the operating characteristics of water pumps and pipe networks, a water pressure curve graph for different time periods is formulated. Formulating the water pressure curve graph for different time periods specifically includes: collecting the operation parameter data of the pipe network system, which requires collecting the flow-head characteristic curve data of the water pump and the parameter data such as the length, diameter, material, and roughness of the pipeline. These data are related to the hydraulic characteristics of the pipe network. According to the collected pipe network data, using the principles of hydraulics, a hydraulic calculation model of the pipe network system is established. This model can calculate the pressure data at each point of the pipe network under different flow conditions. Input the historical average water consumption data of different time periods into the hydraulic calculation model to simulate and calculate the corresponding water pressure distribution of the pipe network. Analyze the pressure distribution conditions for different time periods to determine the allowable minimum pressure and maximum pressure range on the premise of ensuring water supply. And draw the pressure range for different time periods as a water pressure curve graph. On the water pressure curve graph, locate the allowable minimum pressure point and maximum pressure point, and determine their corresponding values as the minimum water pressure reference value and maximum water pressure reference value for this time period.

[0044] For example, during the peak water consumption period, the overall position of the water pressure curve graph is relatively high; while during the low valley period, the overall position of the water pressure curve graph is relatively low. Then, locate the allowable minimum water pressure and maximum water pressure on the water pressure curve graph for each time period, and determine them as the minimum water pressure reference value and maximum water pressure reference value. In this way, during the peak period, the water pressure reference value is relatively high, which can meet the large-flow water consumption demand; while during the low valley period, the reference water pressure value is reduced, which not only ensures the basic water supply pressure but also reduces the ineffective operation of the water pump. The real-time monitored water pressure data only needs to be maintained within the reference value range, and there is no need to frequently start and stop the water pump or sharply adjust the water pump speed to respond to the water consumption fluctuation.

[0045] By setting the dynamic water pressure reference value according to the historical water consumption data, it can ensure the satisfaction of water consumption demands in different time periods, optimize the operation of the water pump, reduce energy consumption loss, extend the service life, and thus improve the economy and reliability of the water supply system.

[0046] Determining the minimum water pressure reference value and maximum water pressure reference value of the water pump in the target area for each time period according to the historical average water consumption of the target area in each time period includes: drawing the water pressure curve graph for each time period according to the historical average water consumption of the target area in each time period; determining the minimum water pressure reference value and maximum water pressure reference value of the water pump in the target area for each time period according to the water pressure curve graph.

[0047] In one example, the basic steps for drawing a water pressure curve graph include: collecting equipment parameters such as water pumps and pipe networks and system flow data; establishing a hydraulic calculation model and inputting the water consumption flow rates at different time periods; running the calculation model to obtain the pressure distribution data for the corresponding time periods; and plotting the pressure data for different time periods as a curve graph. For example, a water pressure change curve graph for 24 hours a day can be drawn. At this time, the abscissa is time and the ordinate is the pressure value. The curve graph can clearly reflect the pressure characteristics during different time periods such as peak and off-peak periods. During the peak period, due to the large water consumption, the position of the pressure curve will be relatively high. While during the off-peak period, the position of the pressure curve will be relatively low. By observing the shape changes of the pressure curve, the water consumption characteristics during different time periods can be intuitively reflected, providing a basis for determining the dynamic water pressure reference value.

[0048] Draw a water pressure curve graph based on the historical average water consumption in the target area for each time period. This can intuitively reflect the water consumption characteristics during different time periods. For example, during the peak period, the position of the water pressure curve graph will be relatively high, while during the off-peak period, the position of the curve will be relatively low. Then, determine the range of the allowable minimum pressure and the allowable maximum pressure according to the shape and position of the water pressure curve graph. The lower limit of the allowable pressure range is taken as the lowest reference value of the water pressure, and the upper limit of the range is taken as the highest reference value of the water pressure. In this way, by observing the position changes of the water pressure curve graph, the water pressure reference values for different time periods can be obtained more intuitively. During the peak period, since the position of the water pressure curve is relatively high, a relatively high highest reference value can be set; while during the off-peak period, since the position of the curve is relatively low, a relatively low lowest reference value can be set. Drawing the water pressure curve graph can intuitively reflect the water consumption characteristics, providing a basis for the scientific determination of the pressure reference value. Setting the reference value according to the curve can realize the dynamic adjustment of the water pressure, making the water pump control more intelligent and economical.

[0049] S103. Obtain the first water consumption within the first preset time period before the current moment, and based on the first water consumption, predict the water consumption trend within the second preset time period after the current moment to obtain a prediction result.

[0050] In one example, the first preset time period here can be set according to the actual situation. Obtain the first water consumption within the first preset time period before the current moment, and based on the first water consumption, predict the water consumption trend within the second preset time period after the current moment. According to the real-time water consumption situation, predict the water consumption change trend within a certain period in the future to realize the intelligent and economical control of the water pump.

[0051] Specifically, it includes: The first preset duration (e.g., 1 hour) and the second preset duration (e.g., 2 hours) can be preset in advance, and the water consumption data of the target area is continuously monitored and recorded. At the current moment, the system retrieves the average water consumption within the first preset duration (i.e., the most recent 1 hour) as the first water consumption. Then, this first water consumption is compared with the historical average water consumption corresponding to this period to determine whether there is an obvious deviation. If the two are basically equivalent, it is predicted that the water consumption will remain stable within the second preset duration (i.e., the next 2 hours) after the current moment; if the first water consumption is significantly higher than the historical average of this period, it is predicted that the future water consumption will continue to increase; if the first water consumption is significantly lower than the historical average, it is predicted that the future water consumption will continue to decrease.

[0052] In this way, based on the monitored data of the phased water consumption, the general trend of water consumption in the future period can be predicted, which serves as the basis for adjusting the pump control parameters. When it is predicted that the water consumption will increase, the pump speed or the water pressure reference value can be increased in advance; when the water consumption is predicted to decrease, the pump output can be appropriately reduced. The anticipation and active response to the water volume change are realized, which not only ensures the water demand but also improves the economy of the pump.

[0053] Combining the first water consumption and the historical average water consumption corresponding to the time period where the second preset duration is located, the water consumption trend within the second preset duration after the current moment is predicted to obtain the prediction result.

[0054] In an example, by comparing the first water consumption with the historical average water consumption of the corresponding period, the water consumption trend within the future preset duration is predicted. This can comprehensively utilize the current real-time data and past experience data for dynamic prediction and grasp the water consumption situation in the future period, providing a basis for the pump operation.

[0055] Specifically, it includes: The system first obtains the water consumption within the first preset duration (e.g., 1 hour) before the current moment as the first water consumption. Then, it finds the average water consumption in the historical data for the time period (such as 9 - 10 am on Monday) to which this first preset duration belongs. The system will compare the two and judge the ratio of the first water consumption obtained in real time to the historical average water consumption of this period. If they are basically equivalent, it is predicted that the water consumption will remain stable within the second preset duration (such as 2 hours) in the future; if the real-time water consumption is significantly higher than the average value, it is predicted that the future water consumption will increase; if the real-time water consumption is significantly lower than the average value, it is predicted that the future water consumption will decrease.

[0056] Combined with the historical average water consumption corresponding to the time period of the first water consumption and the second preset duration, predict the water consumption trend within the second preset duration after the current moment to obtain a prediction result, including: preliminarily predict the water consumption trend within the second preset duration based on the first water consumption to obtain a preliminary prediction result; calculate the difference between the first water consumption and the historical average water consumption corresponding to the time period of the second preset duration; adjust the preliminary prediction result according to the difference to obtain the prediction result.

[0057] In one example, preliminarily predict the future water consumption trend based on the first water consumption and calculate the difference from the historical average water consumption for adjustment. This can predict the water consumption situation by combining real-time data and historical experience, and improve the prediction accuracy through difference correction, providing an accurate basis for pump control. Specifically, the system first only based on the obtained first water consumption, uses methods such as time series analysis to preliminarily predict the water consumption trend within the next second preset duration to obtain a preliminary prediction result.

[0058] Then, the system calculates the difference between the first water consumption and the historical average water consumption of its corresponding time period, that is, the difference between the real-time water consumption and the average value of the historical water consumption in this period. Next, the system will correct the previously obtained preliminary prediction result according to the difference between the two. If the real-time water consumption is greater than the average value, the preliminary prediction result is increased; if the real-time water consumption is less than the average value, the preliminary prediction result is decreased. After correction, the final prediction result is obtained. In this way, first roughly predict according to the real-time water consumption, and then use historical data for correction, which can prevent the prediction deviation from being too large. Combining real-time data and historical experience, the prediction result is more accurate, providing a reliable basis for formulating the subsequent pump operation strategy and realizing economical and effective water resource management.

[0059] S104, according to the prediction result, adjust the minimum water pressure reference value and the maximum water pressure reference value of the pump corresponding to the second preset duration.

[0060] In one example, according to the prediction result, adjust the minimum water pressure reference value and the maximum water pressure reference value of the pump corresponding to the second preset duration, which can realize the dynamic and intelligent adjustment of the water pressure reference value, accurately match the water consumption demand in the future period, ensure the reliability of water supply, and improve the operation economy.

[0061] Specifically, the system first judges whether the water consumption will deviate significantly from the historical average level of this period according to the prediction of the water consumption trend within the next second preset duration. If the predicted water consumption is basically stable, the original water pressure reference value remains unchanged. If the predicted water consumption will increase significantly, appropriately increase the maximum water pressure reference value corresponding to this period to meet the higher water consumption demand. If the predicted water consumption decreases significantly, appropriately reduce the minimum reference value, and reduce the ineffective operation of the pump on the premise of ensuring the basic water supply pressure.

[0062] Through this control mode of predicting water consumption and actively adjusting the water pressure reference value, it can ensure that the water pressure value is always within a reasonable range that matches the future actual water consumption, avoiding both insufficient water supply and excessive water supply. This can reduce the frequent start-stop and large fluctuations in the rotational speed of the water pump, improve the system stability, enable the water pump to operate in the most economical optimal state, reduce energy waste, and extend the service life.

[0063] Adjust the preliminary prediction result according to the difference value to obtain the prediction result, including: if the difference value is positive, increase the preliminary prediction result by a value proportional to the difference value; if the difference value is negative, decrease the preliminary prediction result by a value proportional to the difference value; obtain the prediction result according to the increased or decreased value.

[0064] In an example, after the system obtains the preliminary prediction result of the first water consumption, it will calculate the difference between the first water consumption and the average water consumption in the corresponding historical period. If the calculated difference value is positive, indicating that the first water consumption is higher than the historical average level, then it is necessary to correspondingly increase the preliminary prediction result, because the increase in real-time water consumption indicates that the future water consumption may also increase. At this time, the system will determine a proportional positive value according to the difference value and add it to the preliminary prediction result to obtain the adjusted final prediction value. On the contrary, if the difference value is negative, indicating that the real-time water consumption is lower than the historical average value, then it is necessary to decrease the preliminary prediction result. The system also determines a proportional negative value according to the negative difference value to correspondingly reduce the preliminary prediction result. Making the difference ratio adjustment can correct the prediction based only on the current water consumption and prevent the prediction result from deviating from the normal level. Combining the actual and historical experience to correct the preliminary judgment can improve the prediction accuracy. More accurately predicting the future water consumption is beneficial to formulating a more scientific and reasonable water pump operation strategy, saving water resources and meeting the water demand.

[0065] Obtain the water pressure of the target area at the current moment; if the water pressure is less than the preset minimum reference value or greater than the preset maximum reference value, send an alarm message to the terminal device of the maintenance personnel so that the maintenance personnel can carry out maintenance.

[0066] In an example, obtaining the water pressure of the target area at the current moment, judging whether the water pressure is abnormal, and sending an alarm notification for maintenance can monitor the operation status of the system in real time. Once the abnormal water pressure is detected, it can respond and dispose quickly to ensure the reliable and safe operation of the water supply system.

[0067] Specifically, it includes: setting real-time water pressure monitoring devices in the target area, which can continuously detect and upload the actual water pressure value at the current moment. The system background will obtain this real-time water pressure data and compare it with the set minimum reference water pressure value and maximum reference water pressure value. If it is detected that the real-time water pressure is lower than the minimum reference value or higher than the maximum reference value, an alarm mechanism for abnormal water pressure will be triggered.

[0068] When the alarm is triggered, the system background will automatically generate an alarm message and immediately push it to the mobile terminal of the maintenance personnel, notifying them that there is an abnormal water pressure in the pipe network system and requiring inspection or handling. The alarm message can include the abnormal time, detection point information, real-time water pressure value, etc., which is convenient for the maintenance personnel to quickly locate the problem and conduct disposal.

[0069] Through the real-time monitoring and abnormal alarm mechanism, once the water pressure in the pipe network is abnormal, the maintenance personnel can be notified immediately, enabling the problem to be responded to and processed in a timely manner, avoiding the serious consequences caused by the expansion of the failure, and ensuring the safe and stable operation of the water supply system.

[0070] Obtain the feedback information of the user terminal; according to the feedback information, optimize the minimum reference water pressure value and / or the maximum reference water pressure value of the water pump in the target area during each time period.

[0071] In one example, obtaining the feedback information of the user terminal and optimizing it can adjust the system according to the actual water usage situation of the user, making the operation parameters of the water pump better match the user's needs and improving the user's satisfaction.

[0072] Specifically, it includes: a water pressure feedback module can be set on the user terminal to allow the user to give feedback on the water pressure situation during the current water usage process, such as excessive water pressure, too low water pressure, or obvious water pressure fluctuations. The user feedback will be uploaded to the system background for analysis in real time. After receiving the feedback information, the system background will comprehensively analyze the feedback of a single user and compare it with the water usage situations of other users to judge the rationality of the user feedback. If it is found that within a certain time period, the proportion of user feedback on excessive or too low water pressure exceeds the preset threshold, it indicates that there may be a problem with the setting of the water pressure reference value during the current time period.

[0073] At this time, the system will start the optimization module to adjust the water pressure reference value for this time period according to the feedback situation, such as increasing the minimum reference value or decreasing the maximum reference value. And observe the user's feedback under the new reference value for a period of time. If the problem is improved, save the new setting; otherwise, continue to optimize. In this way, through interaction with the user, the operation settings of the water pump can be better adapted to the actual needs of the user, which is conducive to improving the user's satisfaction.
