Description

Technical Field

[0001] This application relates to the field of water pump control technology, and in particular to a water pump intelligent control method and system. Background Technology

[0002] A water pump is a commonly used fluid machine whose main function is to transport liquids, such as water and oil. It can transport liquids from one place to another and is often used in water supply, drainage, irrigation, industrial production and other fields.

[0003] In related technologies, when using a water pump, the pump's inlet pipe is typically connected to a water tank or other water source, while the outlet pipe is typically connected to various water usage points. When the pump starts, the suction generated inside the pump body draws water from near the inlet pipe into the pump body, thus achieving liquid transport. To facilitate pump operation, the pump's inlet pipe is generally located relatively close to the bottom of the water source to reduce the likelihood of insufficient water to pump due to depletion of the water supply.

[0004] In the aforementioned technologies, since water contains impurities such as silt, which accumulate at the bottom of the water source over time, if the bottom of the water source is not treated regularly, the accumulated silt will get closer and closer to the water pump's inlet pipe. At this time, the suction force generated by the water pump will cause the silt to move towards the inlet pipe, thereby increasing the filtration pressure on the filter screen on the pump body and making the water flow prone to blockage. Therefore, the overall performance of the water pump may be poor, and there is still room for improvement. Summary of the Invention

[0005] In order to reduce the possibility of poor overall performance of the pump during use, this application provides a water pump intelligent control method and system.

[0006] Firstly, this application provides a smart control method for a water pump, employing the following technical solution:

[0007] A method for intelligent control of a water pump, comprising:

[0008] Obtain the pipe-sand gap distance between the inlet pipe and the silt, as well as the inlet pressure of the inlet pipe.

[0009] When the pressure at the inlet of the water pipe is greater than the preset required pressure, determine whether the pipe sand interval distance is greater than the preset benchmark qualified distance;

[0010] If the pipe sand interval distance is greater than the benchmark qualified distance, the water pump will be controlled to maintain its original state;

[0011] If the pipe sand interval distance is not greater than the benchmark qualified distance, the difference between the pipe sand interval distance and the benchmark qualified distance is calculated to determine the required upward movement distance;

[0012] The pressure at the inlet is calculated based on the difference between the pressure at the inlet and the required pressure to determine the pressure that can be reduced at the inlet. The feasible upward movement distance corresponding to the pressure reduction at the inlet is then determined based on the preset pressure matching relationship.

[0013] Determine whether the upward shift of the demand is greater than the feasible upward shift;

[0014] If the required upward movement distance is not greater than the feasible upward movement distance, then control the water inlet pipe to move upward by the required upward movement distance;

[0015] If the required upward movement distance is greater than the feasible upward movement distance, then control the water inlet pipe to move upward by the feasible upward movement distance.

[0016] Optionally, if the required upward movement distance is greater than the feasible upward movement distance, the intelligent pump control method also includes:

[0017] Define the current position of the water inlet pipe as the original position, and establish a lateral movement plane at the original position;

[0018] A pipe movement path is established on the lateral movement plane, and the water inlet pipe is controlled to move according to the pipe movement path to obtain the pipe sand interval distance in real time, and the pipe sand interval distance is defined as the detection interval distance.

[0019] Determine if there are any points where the detection interval distance is greater than the benchmark acceptable distance;

[0020] If there are no points where the detection interval distance is greater than the benchmark acceptable distance, then control the water inlet pipe to move upward from its original position by a feasible upward distance;

[0021] If there are points where the detection interval distance is greater than the benchmark acceptable distance, then the corresponding point is defined as a valid location point, and the detection interval distance obtained at the valid location point is defined as the valid interval distance.

[0022] The maximum effective interval distance is determined according to the preset sorting rules, and the effective location point corresponding to the effective interval distance is defined as the required location point. The water inlet pipe is then controlled to move to the required location point.

[0023] Optionally, after the effective interval distance is determined, the intelligent control method for the water pump also includes:

[0024] Obtain the fixed position of the water inlet;

[0025] The original extension length is determined based on the fixed location of the water inlet and the original location, and the required extension length is determined based on the fixed location of the water inlet and the effective location point.

[0026] The difference between the original extension length and the required extension length is used to determine the length of demand variation.

[0027] The compensation parameters corresponding to the length of demand variation are determined based on the preset compensation matching relationship.

[0028] The selection parameters are determined by calculation based on the compensation parameters and the effective interval distance. The selection parameter with the largest value is determined according to the sorting rules, and the effective location point corresponding to the selection parameter is defined as the required location point.

[0029] Optionally, after the selected parameters are determined, the intelligent control method for the water pump may also include:

[0030] Determine if there are at least two valid location points with the same and maximum selection parameters;

[0031] If there are no at least two valid location points with the largest and the same selection parameter, then the valid location point corresponding to the selection parameter with the largest value shall be determined as the required location point.

[0032] If there are at least two valid location points with the same maximum selection parameter, the valid location point corresponding to the selection parameter with the largest value is defined as the candidate location point, and the detection area is delineated with the candidate location point as the center and the preset unit distance as the radius.

[0033] Within the detection area, the difference is calculated based on the effective interval distance of the candidate location points and the detection interval distance of other points to determine the point difference distance;

[0034] The average difference distance is determined by averaging the distance differences between all points identified from a single candidate location.

[0035] The minimum average difference distance is determined according to the sorting rules, and the candidate location point corresponding to this average difference distance is determined as the required location point.

[0036] Optionally, the steps for establishing a pipe movement path on the lateral movement plane include:

[0037] Establish a fixed interval on the preset timeline with the current time point as the endpoint and a preset fixed duration.

[0038] Within a fixed interval, obtain the total number of valid overall points determined as valid location points and the total number of overall analyses.

[0039] The percentage of valid groups is determined by calculating the number of valid groups and the number of overall analyses.

[0040] Points where the effective overall proportion is greater than the preset baseline demand proportion are defined as theoretically feasible points, and the theoretically feasible points are connected in sequence to determine the pipeline movement path.

[0041] Optionally, the step of connecting the theoretically feasible points sequentially to determine the pipeline movement path includes:

[0042] Randomly select one theoretically feasible point from all theoretically feasible points and connect it to the original location;

[0043] Randomly select one of the remaining theoretically feasible points and connect it with the previously selected theoretically feasible point, and continue to select until there are no more theoretically feasible points to choose from;

[0044] Based on the current theoretically feasible point connections, determine the feasible connection paths, and based on the feasible connection paths, determine the feasible connection distances.

[0045] The feasible connecting route with the smallest value is determined according to the sorting rules, and the feasible connecting path corresponding to this feasible connecting route is determined as the pipeline movement path.

[0046] Optionally, after the feasible connecting distance is determined, the intelligent control method for the water pump also includes:

[0047] Determine whether there exist at least two identical feasible connected paths with the minimum feasible connected distance;

[0048] If there are no at least two feasible connecting paths with the smallest and the same possible connecting distance, then the pipeline movement path is determined based on the feasible connecting path corresponding to the unique feasible connecting path with the smallest possible value.

[0049] If there are at least two feasible connecting paths with the smallest and the same feasible connecting distance, then the feasible connecting path corresponding to the feasible connecting path with the smallest value is defined as the candidate connecting path, and the number of times each point on the candidate connecting path is used as the required location point is obtained in a fixed interval.

[0050] Points with non-zero demand frequency are defined as permit points, and the number of permits is determined by counting the permit points on each alternative connected path.

[0051] The maximum permitted quantity is determined according to the sorting rules, and the alternative connecting path corresponding to that permitted quantity is determined as the pipeline movement path.

[0052] Secondly, this application provides an intelligent control system for a water pump, which adopts the following technical solution:

[0053] A smart control system for water pumps, comprising:

[0054] The acquisition module is used to acquire the pipe-sand gap distance between the water inlet pipe and the silt, as well as the water inlet pressure at the water inlet pipe opening.

[0055] The processing module, connected to the acquisition and judgment modules, is used for information storage and processing;

[0056] The judgment module, connected to the acquisition and processing modules, is used for judging information.

[0057] When the pressure at the inlet of the water pipe is greater than the preset required pressure, the judgment module determines whether the pipe sand interval distance is greater than the preset benchmark qualified distance.

[0058] If the judgment module determines that the pipe sand interval distance is greater than the benchmark qualified distance, the processing module controls the water pump to maintain the original state;

[0059] If the judgment module determines that the pipe-sand interval distance is not greater than the benchmark qualified distance, the processing module calculates the difference between the pipe-sand interval distance and the benchmark qualified distance to determine the required upward movement distance.

[0060] The processing module calculates the difference between the inlet pressure and the required pressure to determine the pressure that can be reduced at the inlet, and determines the feasible upward movement distance corresponding to the pressure reduction at the inlet based on the preset pressure matching relationship.

[0061] The decision module determines whether the upward movement distance of the requirement is greater than the feasible upward movement distance.

[0062] If the judgment module determines that the required upward movement distance is not greater than the feasible upward movement distance, the processing module controls the water inlet pipe to move upward by the required upward movement distance;

[0063] If the judgment module determines that the required upward movement distance is greater than the feasible upward movement distance, the processing module controls the water inlet pipe to move upward by the feasible upward movement distance.

[0064] In summary, this application includes at least one of the following beneficial technical effects:

[0065] During the use of the water pump, the distance between the inlet pipe and the sediment is analyzed to maintain this distance when the water pressure is sufficient. This reduces the likelihood of the water pump drawing large amounts of sediment into the filter screen, thus improving the overall performance of the water pump. The lateral movement of the inlet pipe can be controlled to determine the position that meets the usage requirements without longitudinal movement, so that the water pump can be used better subsequently.

[0074] To make the purpose, technical solution, and advantages of this application clearer, the following is combined with Figures 1-8 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0075] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0076] This application discloses an intelligent control method for a water pump. During the use of the water pump, the distance between the inlet of the water inlet and the sediment is analyzed when the water pressure requirement is met. When the two are close, the movement of the inlet pipe can be controlled, so that the water pump can draw water better while reducing the sediment from moving with the liquid to the filter screen. This reduces the occurrence of the filter screen being blocked by sediment, which affects the liquid delivery and improves the overall performance of the water pump.

[0077] Reference Figure 1 The method flow of the intelligent control method for water pumps includes the following steps:

[0078] Step S100: Obtain the pipe-sand gap distance between the water inlet pipe and the silt, as well as the water inlet pressure at the water inlet pipe opening.

[0079] The pipe-sand interval distance is the distance between the inlet of the water pipe and the silt obtained by the distance sensor installed on the outer wall of the inlet of the water pipe. The inlet of the water pipe is placed vertically at the water source, and the probe of the distance sensor is set vertically downward. The inlet pressure is the external pressure value obtained by the pressure sensor installed on the outer wall of the inlet of the water pipe when the water pump is not operating. This pressure value is also the water pressure value.

[0080] Step S101: When the pressure at the inlet of the water pipe is greater than the preset required pressure, determine whether the pipe sand interval distance is greater than the preset benchmark qualified distance.

[0081] The required pressure is the minimum inlet pressure set by the staff for the water pump's inlet pipe to effectively draw water. When the inlet pressure is greater than the required pressure, it indicates that the inlet pipe is already submerged in the water and can effectively draw water. The benchmark acceptable distance is the minimum pipe-sand interval distance set by the staff to ensure that the water pump's suction force will not generate a strong suction force on sediment. The purpose of this judgment is to determine whether the water pump will generate a strong suction force on sediment and other impurities, causing them to adhere to the filter screen.

[0082] Step S1011: If the pipe sand interval distance is greater than the benchmark qualified distance, then control the water pump to maintain the original state.

[0083] When the interval between pipes is greater than the standard acceptable distance, it means that the water pump is not easily able to adsorb the silt onto the filter screen. At this time, it is sufficient to control the water pump to operate normally.

[0084] Step S1012: If the pipe-sand interval distance is not greater than the benchmark qualified distance, the difference between the pipe-sand interval distance and the benchmark qualified distance is calculated to determine the required upward movement distance.

[0085] When the sand-filled pipe interval is not greater than the benchmark acceptable distance, it means that the suction generated by the water pump will adsorb the sand onto the filter screen. This situation needs to be addressed. The required upward movement distance is the distance that needs to be moved upward in order for the water pump to function better. It is determined by subtracting the sand-filled pipe interval from the benchmark acceptable distance.

[0086] Step S102: Calculate the difference between the inlet pressure and the required pressure to determine the pressure that can be reduced at the inlet, and determine the feasible upward movement distance corresponding to the pressure that can be reduced at the inlet according to the preset pressure matching relationship.

[0087] The pressure reduction at the pipe inlet is the external water pressure that can be reduced under the condition that the water pump is in operation. It is determined by subtracting the required pressure from the pressure at the inlet pipe. The feasible upward movement distance is the distance that the inlet pipe can be moved upward under the condition that the water pressure meets the requirements. The pressure reduction of the pipe is the water pressure difference. The relationship between water pressure and water depth can be determined by the water pressure calculation formula. Based on this, the corresponding pressure matching relationship should be established and stored in advance.

[0088] Step S103: Determine whether the upward movement distance of the demand is greater than the feasible upward movement distance.

[0089] The purpose of the assessment is to determine whether the current defect can be overcome by moving the water inlet pipe upwards.

[0090] Step S1031: If the required upward movement distance is not greater than the feasible upward movement distance, then control the water inlet pipe to move upward by the required upward movement distance.

[0091] When the required upward movement distance is no greater than the feasible upward movement distance, it indicates that the current defect of adsorbing silt can be overcome by moving the pipe upward. In this case, normal control of the water inlet pipe to move upward by the required distance is sufficient. To facilitate the movement of the water inlet pipe, the part connecting the water inlet pipe to the pump body can be set as a foldable flexible hose, such as a corrugated hose. The movement of the water inlet pipe can be achieved by installing a mobile device at the inlet of the water inlet pipe. This mobile device is wirelessly connected to the system. When a signal is output that the water inlet pipe needs to be moved, the mobile device can move in the water to carry the water inlet pipe synchronously. The mobile device can be a device similar to a submersible, which will not be elaborated here.

[0092] Step S1032: If the required upward movement distance is greater than the feasible upward movement distance, then control the water inlet pipe to move upward by the feasible upward movement distance.

[0093] When the required upward movement distance is greater than the feasible upward movement distance, it means that the required upward movement distance cannot be completely moved to overcome the existing defects. At this time, the feasible upward movement distance of the water inlet pipe should be controlled to maximize the distance between the pipe opening and the silt, thereby minimizing the amount of silt adsorbed in the filter screen of the pump body.

[0094] Reference Figure 2 If the required upward movement distance is greater than the feasible upward movement distance, the intelligent control method for the water pump also includes:

[0095] Step S200: Define the current position of the water inlet pipe as the original position, and establish a lateral movement plane at the original position.

[0096] Define the original position to mark the location of the inlet pipe before it was moved, so as to facilitate subsequent analysis; the lateral movement plane is a plane that runs through the original position and is parallel to the bottom surface of the water source.

[0097] Step S201: Establish a pipe movement path on the horizontal movement plane, and control the water inlet pipe to move according to the pipe movement path to obtain the pipe sand interval distance in real time, and define the pipe sand interval distance as the detection interval distance.

[0098] The pipeline movement path is the path along which the inlet pipeline moves on the horizontal movement plane. This path can be set in advance by the staff or determined according to the methods in steps S500-S503. When the inlet pipeline moves according to the pipeline movement path, the distance between the bottom sediment and the pipeline will change due to the different sediment deposition amounts. At this time, the corresponding pipe-sand interval distance is defined as the detection interval distance for easy subsequent analysis.

[0099] Step S202: Determine whether there are any points where the detection interval distance is greater than the benchmark acceptable distance.

[0100] The purpose of the judgment is to determine whether there are any points on the horizontal movement plane where the water pump can operate better.

[0101] Step S2021: If there are no points where the detection interval distance is greater than the benchmark qualified distance, then control the water inlet pipe to move upward by a feasible distance from its original position.

[0102] When there are no points with a detection interval greater than the benchmark acceptable distance, it means that there are no points on the horizontal movement plane where the water inlet pipe can be operated well. In this case, the water inlet pipe can be controlled to return to its original position and move upward.

[0103] Step S2022: If there are points where the detection interval distance is greater than the benchmark qualified distance, then the corresponding point is defined as a valid location point, and the detection interval distance obtained at the valid location point is defined as the valid interval distance.

[0104] When there are points where the detection interval distance is greater than the benchmark acceptable distance, it means that the pump operation requirements can be met without moving upwards. In this case, the corresponding point is defined as an effective location point to distinguish different location points and facilitate subsequent analysis. At the same time, an effective interval distance is defined to mark the detection interval distance corresponding to the effective location point, which also facilitates subsequent analysis.

[0105] Step S203: Determine the effective interval distance with the largest value according to the preset sorting rules, define the effective location point corresponding to the effective interval distance as the required location point, and control the water inlet pipe to move to the required location point.

[0106] The sorting rules are methods set by the staff to sort numerical values, such as the bubble sort method. The sorting rules can determine the effective interval distance with the largest value. That is, at this position, the pump can not only operate well, but also control the water inlet pipe to descend to meet the water pressure requirements as the water level drops. At this time, the corresponding effective position point is defined as the demand position point to control the movement of the water inlet pipe, so that the water inlet pipe can move to the place that meets the requirements and the water pump can operate well.

[0107] Reference Figure 3 After the effective interval distance is determined, the intelligent control method for water pumps also includes:

[0108] Step S300: Obtain the fixed position of the water inlet.

[0109] The fixed position of the water inlet is the position of the pipe connected to the flexible part of the water inlet pipe in the pump body. No matter how the water inlet pipe is moved or adjusted, as long as the pump body does not move, the fixed position of the water inlet will not change. It can be determined by installing a positioning device at the corresponding connection.

[0110] Step S301: Determine the original extension length based on the fixed position of the water inlet and the original position, and determine the required extension length based on the fixed position of the water inlet and the effective position point.

[0111] The original extension length is the distance between the fixed water inlet position and the original position, which is the length that the water inlet pipe needs to be extended. The required extension length is the distance between the fixed water inlet position and the effective position point.

[0112] Step S302: Calculate the difference between the original extension length and the required extension length to determine the length of demand variation.

[0113] The required change length is the length change of the water inlet pipe, which is the difference between the original extension length and the required extension length. This difference is an absolute value. The larger the value, the greater the length change. In this case, in order for the pump to still generate good suction to the water, the range of adjustment of the usage frequency is larger, and the overall operation is more complicated.

[0114] Step S303: Determine the compensation parameters corresponding to the length of demand change based on the preset compensation matching relationship.

[0115] The compensation parameter is a parameter used to select the effective position point after considering the length of demand change. Different compensation parameters correspond to different lengths of demand change. When the length of demand change is smaller, it means that the required length of change is smaller. At this time, the pump body needs to be adjusted less frequently, and the overall operation is more convenient. The corresponding compensation parameter is also smaller. The compensation matching relationship between the two is determined and stored in advance by the staff through multiple tests.

[0116] Step S304: Calculate and determine the selection parameters based on the compensation parameters and the effective interval distance, and determine the selection parameter with the largest value according to the sorting rules, and define the effective location point corresponding to the selection parameter as the required location point.

[0117] The selected parameter is the effective interval distance minus the compensation parameter. The larger this value is, the more suitable the corresponding effective location point is for the placement of the water inlet pipe. Therefore, the selection parameter with the largest value can be determined by the sorting rules. At this time, the corresponding effective location point can be defined as the required location point for the water inlet pipe to be moved.

[0118] Reference Figure 4 After the selected parameters are determined, the intelligent control method for water pumps also includes:

[0119] Step S400: Determine whether there are at least two valid location points with the same and maximum selection parameters.

[0120] The purpose of the judgment is to determine whether there are multiple valid location points that meet the requirements, so as to determine the unique required location point.

[0121] Step S4001: If there are no at least two valid location points with the largest and the same selection parameter, then the valid location point corresponding to the selection parameter with the largest value is determined as the required location point.

[0122] If there are no at least two valid location points with the largest and the same selection parameters, it means that there is only one valid location point that meets the requirements. In this case, it can be determined as the required location point.

[0123] Step S4002: If there are at least two valid location points with the same maximum selection parameter, the valid location point corresponding to the selection parameter with the largest value is defined as the candidate location point, and the detection area is delineated with the candidate location point as the center and a preset unit distance as the radius.

[0124] When there are at least two valid location points with the same maximum selection parameter, it indicates that there are multiple valid location points that meet the requirements. At this time, further screening is required. Candidate location points are defined to distinguish the valid location points that meet the requirements, which facilitates subsequent analysis. The unit distance is a fixed distance set by the staff, and the detection area is delineated to facilitate the analysis and processing of the area around the candidate location points.

[0125] Step S401: In the detection area, calculate the difference based on the effective interval distance of the candidate location points and the detection interval distance of other points to determine the point difference distance.

[0126] The point difference distance is the difference between the detection interval distance of other points in the defined detection area and the effective interval distance of the candidate point. This difference is an absolute value. If some points in the detection area do not have a detection interval distance, only the data with a detection interval distance will be used for analysis.

[0127] Step S402: Calculate the mean difference distance based on the average difference distance of all points determined by a single candidate location point.

[0128] The average difference distance is the average of the difference distances of all points.

[0129] Step S403: Determine the average difference distance with the smallest value according to the sorting rules, and determine the candidate location point corresponding to the average difference distance as the required location point.

[0130] The average difference distance with the smallest value can be determined by the sorting rules. The smaller the average difference distance, the closer the detection interval distance of each point in the detection area is to the effective interval distance of the candidate location point. In other words, the mud and sand below the detection area are more level. At this time, it is less likely that a certain part of the mud and sand will accumulate too quickly in subsequent use, requiring the water inlet pipe to be moved again.

[0131] Reference Figure 5 The steps for establishing a pipeline movement path on the lateral movement plane include:

[0132] Step S500: Establish a fixed interval on the preset timeline with the current time point as the endpoint and a preset fixed duration as the width.

[0133] The time axis is a coordinate axis formed by combining various time points, pointing from the time points that have been passed to the time points that have not yet been reached. The fixed duration is the duration set by the staff to obtain historical usage data of the water pump, such as three years, to establish a fixed interval for data acquisition and analysis.

[0134] Step S501: Obtain the total number of valid locations and the total number of overall analyses for each point within a fixed interval.

[0135] The total number of overall analysis counts is the total number of times the water inlet pipe is moved laterally within a fixed interval to mark each point as a valid location point. The total number of valid overall counts is the total number of times a point is determined as a valid location point within the total number of overall analysis counts.

[0136] Step S502: Calculate and determine the percentage of valid groups based on the number of valid groups and the number of overall analyses.

[0137] The effective overall percentage, which is the percentage of points that are identified as effective locations, is determined by dividing the number of effective overall points by the number of overall analyses.

[0138] Step S503: Define the points where the effective overall proportion is greater than the preset baseline demand proportion as theoretically feasible points, and connect each theoretically feasible point in sequence to determine the pipeline movement path.

[0139] The baseline demand ratio is the minimum effective overall ratio that must be met when the point is frequently identified as a valid location point, as set by the staff. When the effective overall ratio is greater than the baseline demand ratio, it means that the point has a high probability of being identified as a valid location point. At this time, it is identified as a theoretically feasible point, and the pipeline movement path is determined by connecting the theoretically feasible points, thereby enabling the determination of the detection interval distance at each theoretically feasible point. The method for connecting theoretically feasible points can be random connection or connection according to the method in steps S600-S603, which will not be elaborated here.

[0140] Reference Figure 6 The steps for connecting the theoretically feasible points in sequence to determine the pipeline movement path include:

[0141] Step S600: Randomly select one theoretically feasible point from all theoretically feasible points and connect it to the original location.

[0142] By randomly selecting one theoretically feasible point from all theoretically feasible points, it can be connected to the original location, thus facilitating the removal of the water inlet pipe from the original location to test the theoretically feasible point.

[0143] Step S601: Randomly select one of the remaining theoretically feasible points and connect it with the previously selected theoretically feasible point, and continue to select until there are no more theoretically feasible points to choose from.

[0144] From the remaining theoretically feasible points, a theoretically feasible point is randomly selected and connected to a previously determined theoretically feasible point. This allows the water inlet pipe to move to a new theoretically feasible point for testing after the previous theoretically feasible point has been tested. Through continuous selection, theoretically feasible points can be connected sequentially.

[0145] Step S602: Determine feasible connection paths based on the current theoretically feasible point connection situation, and determine feasible connection distances based on feasible connection paths.

[0146] A feasible connecting path is the path obtained by connecting all theoretically feasible points from front to back, and the feasible connecting distance is the total distance of the feasible connecting path.

[0147] Step S603: Determine the feasible connecting route with the smallest value according to the sorting rules, and determine the feasible connecting path corresponding to the feasible connecting route as the pipeline movement path.

[0148] The sorting rules can be used to determine the feasible connecting path with the smallest value. That is, when the water inlet pipe moves according to the feasible connecting path corresponding to this feasible connecting path, the overall efficiency is the highest. At this time, it can be defined as the pipe movement path.

[0149] Reference Figure 7 Once the feasible connecting distance is determined, the intelligent control method for water pumps also includes:

[0150] Step S700: Determine whether there are at least two feasible connected paths that are identical and have the shortest possible connected distance.

[0151] The purpose of this judgment is to determine whether there are multiple feasible connected paths that meet the requirements.

[0152] Step S7001: If there are no at least two feasible connecting paths with the smallest and the same length, then determine the pipeline movement path based on the feasible connecting path corresponding to the unique feasible connecting path with the smallest length.

[0153] When there are no at least two feasible connected paths with the shortest and the same length, it means that only one feasible connected path can be determined as the pipeline movement path. In this case, the pipeline movement path determination can proceed normally.

[0154] Step S7002: If there are at least two feasible connected paths with the smallest and the same feasible connected path, then the feasible connected path corresponding to the feasible connected path with the smallest value is defined as the candidate connected path, and the number of times each point on the candidate connected path is used as the required location point is obtained in a fixed interval.

[0155] When there are at least two feasible connecting paths with the shortest and the same length, it indicates that there are multiple feasible connecting paths that meet the requirements. At this point, they need to be filtered. Candidate connecting paths are defined to distinguish different feasible connecting paths for easier subsequent analysis. The number of times a point on a candidate connecting path is determined to be the required location is the total number of times it has been visited.

[0156] Step S701: Define the points with non-zero demand as permit points, and count the permit points on each alternative connected path to determine the permit quantity.

[0157] Define permit points to distinguish points that may serve as demand locations; the number of permits is the total number of all permit points.

[0158] Step S702: Determine the maximum permitted quantity according to the sorting rules, and determine the alternative connected path corresponding to the permitted quantity as the pipeline movement path.

[0159] The maximum permissible quantity can be determined by sorting rules, which means that the path on which the required location point is more likely to be located is the path on which the alternative connected path is determined as the pipeline movement path for the water inlet pipeline to move.

[0160] Reference Figure 8 Based on the same inventive concept, embodiments of the present invention provide a smart control system for a water pump, comprising:

[0161] The acquisition module is used to acquire the pipe-sand gap distance between the water inlet pipe and the silt, as well as the water inlet pressure at the water inlet pipe opening.

[0162] The processing module, connected to the acquisition and judgment modules, is used for information storage and processing;

[0163] The judgment module, connected to the acquisition and processing modules, is used for judging information.

[0164] When the pressure at the inlet of the water pipe is greater than the preset required pressure, the judgment module determines whether the pipe sand interval distance is greater than the preset benchmark qualified distance.

[0165] If the judgment module determines that the pipe sand interval distance is greater than the benchmark qualified distance, the processing module controls the water pump to maintain the original state;

[0166] If the judgment module determines that the pipe-sand interval distance is not greater than the benchmark qualified distance, the processing module calculates the difference between the pipe-sand interval distance and the benchmark qualified distance to determine the required upward movement distance.

[0167] The processing module calculates the difference between the inlet pressure and the required pressure to determine the pressure that can be reduced at the inlet, and determines the feasible upward movement distance corresponding to the pressure reduction at the inlet based on the preset pressure matching relationship.

[0168] The decision module determines whether the upward movement distance of the requirement is greater than the feasible upward movement distance.

[0169] If the judgment module determines that the required upward movement distance is not greater than the feasible upward movement distance, the processing module controls the water inlet pipe to move upward by the required upward movement distance;

[0170] If the judgment module determines that the required upward movement distance is greater than the feasible upward movement distance, the processing module controls the water inlet pipe to move upward by the feasible upward movement distance;

[0171] The lateral movement control module can move the water inlet pipe laterally when the pipe opening is close to the silt, thus making it easier to determine the suitable location for pipe placement.

[0172] The demand location determination module comprehensively analyzes the required pipeline extension length and the distance between the pipeline and the silt to determine a more suitable demand location.

[0173] The valid location point filtering module is used to filter multiple valid location points that meet the requirements.

[0174] The pipeline movement path determination module is used to determine a more suitable pipeline movement path for inlet pipeline movement analysis.

[0175] The path analysis module analyzes the path length of each path to determine the shortest pipeline movement path, thereby improving overall operation efficiency.

[0176] The path filtering module is used to filter multiple feasible connected paths that meet the requirements.

In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the system, device, and unit described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.
