Description

Technical Field

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

[0002] A water pump is a commonly used fluid machinery 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 the related art, when a water pump is used, the water inlet pipe of the water pump is usually connected to a water tank or other water source, and the water outlet pipe is usually connected to various water use points. When the water pump is started, the suction force generated inside the pump body can suck the water near the water inlet pipe into the pump body, thereby realizing the liquid transportation. In order to facilitate the use of the water pump, the water inlet pipe of the water pump is generally closer to the bottom of the water source to reduce the situation where the water source storage water volume is reduced and water cannot be pumped.

[0004] In the above-mentioned related technologies, since impurities such as silt may be mixed in the water, they will be deposited at the bottom of the water source over time. If the bottom of the water source is not treated regularly, the deposited silt will get closer and closer to the water inlet pipe of the water pump. At this time, the suction force generated by the water pump acts on the silt, causing the silt to move to the water inlet pipe, thereby increasing the filtering pressure of the filter on the pump body and making it easy for the water flow to be blocked. Therefore, the overall use effect of the water pump may be poor, and there is still room for improvement. Summary of the invention

[0023] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 8 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0025] The embodiment of the present application discloses an intelligent control method for a water pump. During the use of the water pump, the distance between the pipe mouth of the water inlet pipe and the sediment is analyzed when the water pressure requirement is met, so that the movement of the water inlet pipe can be controlled when the two are close, so that the water pump can absorb water better while reducing the sediment moving with the liquid to the filter screen, thereby reducing the occurrence of the filter screen being blocked by sediment and affecting the liquid delivery, and improving the overall use effect of the water pump during use.

[0026] Reference Figure 1 The method flow of the water pump intelligent control method includes the following steps: Step S100: Obtain the pipe-sand spacing distance between the water inlet pipe and the sediment and the water inlet pipe opening pressure of the water inlet pipe opening.

[0027] The pipe-sand interval distance is the distance value between the water inlet pipe orifice and the sediment obtained by the distance sensor installed on the outer side wall of the water inlet pipe orifice. The water inlet pipe is placed vertically at the water source, and the probe of the distance sensor is set vertically downward; the water inlet pipe orifice pressure is the external pressure value obtained by the pressure sensor installed on the outer side wall of the water inlet pipe orifice when the water pump is not operating, which is also the water pressure value.

[0028] Step S101: when the water inlet pressure is greater than the preset required pressure, determining whether the pipe-sand spacing distance is greater than the preset reference qualified distance.

[0029] The demand pressure is the minimum water inlet pressure set by the staff to determine that the water inlet pipe of the water pump can absorb water well. When the water inlet pressure is greater than the demand pressure, it means that the water inlet pipe has been extended into the water and can absorb water well. The benchmark qualified distance is the minimum pipe-sand spacing distance set by the staff that will not produce strong suction on the sediment under the current water pump suction. The purpose of the judgment is to know whether the current water pump will produce a strong suction on impurities such as sediment and cause the impurities to adhere to the filter net.

[0030] Step S1011: If the pipe-sand spacing distance is greater than the reference qualified distance, the water pump is controlled to maintain the original state.

[0031] When the pipe-sand spacing distance is greater than the benchmark qualified distance, it means that it is difficult for the water pump to adsorb the sediment onto the filter net. At this time, the water pump can be controlled to operate normally.

[0032] Step S1012: If the pipe-sand spacing distance is not greater than the benchmark qualified distance, a difference calculation is performed based on the pipe-sand spacing distance and the benchmark qualified distance to determine the required upward movement distance.

[0033] When the pipe-sand spacing distance is not greater than the benchmark qualified distance, it means that the suction generated by the water pump at this time will adsorb the sediment onto the filter net, and this situation needs to be dealt with at this time; the required upward distance is the distance that needs to be moved upward in order for the water pump to work better, which is determined by subtracting the pipe-sand spacing distance from the benchmark qualified distance.

[0034] Step S102: Calculate the difference between the water inlet pressure and the required pressure to determine the reducible pressure at the outlet, and determine the feasible upward movement distance corresponding to the reducible pressure at the outlet according to a preset pressure matching relationship.

[0035] The reducible pressure at the pipe outlet is the external water pressure that can be reduced under the condition that the water pump can be used, and is determined by subtracting the required pressure from the water inlet pressure. The feasible upward distance is the distance that the water inlet pipe can be controlled to move upward when the water pressure meets the requirements. The reducible pressure at the pipe outlet is the water pressure difference. The relationship between water pressure and water depth can be determined by the water pressure calculation formula, and the corresponding pressure matching relationship is established and stored in advance according to the situation.

[0036] Step S103: Determine whether the required upward moving distance is greater than the feasible upward moving distance.

[0037] The purpose of the judgment is to find out whether the current defects can be overcome by moving the water inlet pipe upward.

[0038] Step S1031: If the required upward moving distance is not greater than the feasible upward moving distance, the water inlet pipe is controlled to move upward by the required upward moving distance.

[0039] When the required upward moving distance is not greater than the feasible upward moving distance, it means that the current defect of adsorbing mud and sand can be overcome by moving upward. At this time, the water inlet pipe can be normally controlled to move upward the required moving distance. In order to facilitate the movement of the water inlet pipe, the part of the water inlet pipe connected to the pump body can be set as a foldable hose, such as a corrugated hose; wherein, the movement of the water inlet pipe can be achieved by installing a mobile device at the pipe mouth of the water inlet pipe, and the mobile device is wirelessly connected to the system. When the signal that the water inlet pipe needs to move is output, the mobile device can move in the water to carry the water inlet pipe to move synchronously; wherein the mobile device can be a device similar to a submersible, which is not described here.

[0040] Step S1032: If the required upward moving distance is greater than the feasible upward moving distance, the water inlet pipe is controlled to move upward by the feasible upward moving distance.

[0041] When the required upward moving distance is greater than the feasible upward moving distance, it means that the required upward moving distance cannot be fully moved upward to overcome the current defects. At this time, the feasible upward moving distance of the water inlet pipe is controlled to maximize the distance between the pipe mouth and the sediment, thereby minimizing the sediment adsorbed in the filter net of the pump body.

[0042] Reference Figure 2 If the required upward movement distance is greater than the feasible upward movement distance, the water pump intelligent control method further includes: 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.

[0043] The original position is defined to identify the position of the water inlet pipe before it is moved, so as to facilitate subsequent analysis; the lateral movement plane is a plane that passes through the original position and is parallel to the bottom surface of the water source.

[0044] Step S201: establishing a pipeline moving path on a lateral moving plane, and controlling the water inlet pipeline to move according to the pipeline moving path to obtain the pipe-sand interval distance in real time, and defining the pipe-sand interval distance as the detection interval distance.

[0045] The pipeline movement path is the path along which the water inlet pipeline moves on the horizontal movement plane. The path can be set in advance by the staff, or determined according to the method of step S500-step S503. When the water inlet pipeline is controlled to move according to the pipeline movement path, the distance between the bottom sediment and the pipeline will change due to different sediment deposition amounts. At this time, the corresponding pipe-sand interval distance is defined as the detection interval distance for identification, which is convenient for subsequent analysis.

[0046] Step S202: Determine whether there are points whose detection interval distance is greater than the reference qualified distance.

[0047] The purpose of the judgment is to find out whether there is a point on the lateral moving plane where the water pump can perform better operation.

[0048] Step S2021: If there is no point where the detection interval distance is greater than the reference qualified distance, the water inlet pipe is controlled to move upward from the original position by a feasible upward distance.

[0049] When there is no point where the detection interval distance is greater than the benchmark qualified distance, it means that there is no point on the lateral moving plane where the water inlet pipe can operate well. At this time, the water inlet pipe can be controlled to return to the original position and move upward.

[0050] Step S2022: If there is a point where the detection interval distance is greater than the reference qualified distance, the corresponding point is defined as a valid position point, and the detection interval distance obtained at the valid position point is defined as the effective interval distance.

[0051] When there are points where the detection interval distance is greater than the benchmark qualified distance, it means that the water pump operation requirements can be met without moving upward. At this time, the corresponding points are defined as valid position points to distinguish different position points for subsequent analysis. At the same time, the effective interval distance is defined to identify the detection interval distance corresponding to the valid position point for subsequent analysis.

[0052] Step S203: determining the effective interval distance with the largest value according to a preset sorting rule, defining the effective position point corresponding to the effective interval distance as the required position point, and controlling the water inlet pipe to move to the required position point.

[0053] The sorting rule is a method set by the staff to sort the size of values, such as the bubbling method. The sorting rule can be used to determine the effective interval distance with the largest value, that is, the pump body can not only operate well at this position, but also can still control the water inlet pipe to drop when the water level drops subsequently to meet the water pressure requirements; 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 be moved to a place that meets the requirements so that the water supply pump can operate better.

[0054] Reference Figure 3 After the effective interval distance is determined, the water pump intelligent control method also includes: Step S300: Obtain a fixed water inlet position.

[0055] The fixed water inlet position is the position of the pipe in the pump body that is connected to the hose part of the water inlet pipe. That is, no matter how the water inlet pipe is moved and adjusted, as long as the pump body does not move, the fixed water inlet position will not change. It can be determined by installing a positioning device at the corresponding connection.

[0056] Step S301: determining an original extension length according to the fixed water inlet position and the original position, and determining a required extension length according to the fixed water inlet position and the effective position point.

[0057] The original extension length is the distance between the fixed water inlet position and the original position, that is, the length of the water inlet pipe that needs to be extended. The required extension length is the distance between the fixed water inlet position and the effective position point.

[0058] Step S302: Calculate the difference between the original extension length and the required extension length to determine the required change length.

[0059] The required change in length is the length change required for the water inlet pipe, which is the difference between the original extension length and the required extension length. The difference is an absolute value. The larger the value, the greater the length change. At this time, in order for the pump body to still generate suction for the water body, the larger the range of adjustment of the frequency of use is required, and the more troublesome the overall operation is.

[0060] Step S303: determining compensation parameters corresponding to the required change length according to a preset compensation matching relationship.

[0061] The compensation parameter is the parameter for selecting the effective position point after considering the demand change length. Different demand change lengths correspond to different compensation parameters. When the demand change length is smaller, the required change length is smaller. At this time, the frequency of adjustment of the pump body is smaller, the overall operation is more convenient, and the corresponding compensation parameter is smaller. The compensation matching relationship between the two is determined by the staff through multiple tests in advance and entered into storage.

[0062] Step S304: Calculate and determine the selection parameter according to the compensation parameter and the effective interval distance, and determine the selection parameter with the largest value according to the sorting rule, and define the effective position point corresponding to the selection parameter as the required position point.

[0063] The selection parameter is the effective interval distance minus the compensation parameter. The larger the value, the more suitable the corresponding effective position point is for the placement of the water inlet pipe. Therefore, the selection parameter with the largest value can be determined through the sorting rule. At this time, the corresponding effective position point can be defined as the required position point for the movement of the water inlet pipe.

[0064] Reference Figure 4 After the selection parameters are determined, the water pump intelligent control method also includes: Step S400: Determine whether there are at least two valid position points with the largest and identical selection parameters.

[0065] The purpose of the judgment is to find out whether there are multiple valid location points that meet the requirements, so as to determine the only required location point.

[0066] Step S4001: If there are not at least two valid location points with the largest and identical selection parameters, the valid location point corresponding to the selection parameter with the largest value is determined as the required location point.

[0067] When there are not at least two valid location points with the largest and identical selection parameters, it means that there is only one valid location point that meets the requirements, and in this case, it can be determined as the required location point.

[0068] Step S4002: If there are at least two valid position points with the largest and identical selection parameters, the valid position point corresponding to the selection parameter with the largest value is defined as the candidate position point, and the detection area is delineated with the candidate position point as the center and the preset unit distance as the radius.

[0069] When there are at least two valid location points with the largest and identical selection parameters, it means that there are multiple valid location points that meet the requirements, and they need to be further screened and processed. Alternative location points are defined to distinguish the valid location points that meet the requirements for subsequent analysis. The unit distance is a fixed distance set by the staff, and the detection area is delineated to facilitate analysis and processing of the area around the alternative location points.

[0070] Step S401: performing difference calculation based on the effective interval distance of the candidate position points and the detection interval distances of other points in the detection area to determine the point difference distance.

[0071] The point difference distance is the difference between the detection interval distance of other points in the designated detection area and the effective interval distance of the alternative location point. The difference is an absolute value. If the detection interval distance is not obtained for some points in the detection area, only the data with the detection interval distance is used for analysis.

[0072] Step S402: Calculate the average of all point difference distances determined according to a single candidate position point to determine an average difference distance.

[0073] The average difference distance is the average of all point difference distances.

[0074] Step S403: determining the average difference distance with the smallest value according to the sorting rule, and determining the candidate location point corresponding to the average difference distance as the required location point.

[0075] The sorting rules can be used to determine the average difference distance with the smallest value. The smaller the average difference distance is, the closer the detection interval distance of each point in the detection area is to the effective interval distance of the alternative position point, that is, the corresponding mud and sand below the detection area is flatter. At this time, in subsequent use, it is not easy for a part of the mud and sand to accumulate too quickly and require the water inlet pipe to be moved again.

[0076] Reference Figure 5 The steps of establishing a pipeline moving path on the lateral moving plane include: Step S500: establishing a fixed interval on a preset time axis with the current time point as the end point and a width of a preset fixed time length.

[0077] The time axis is a coordinate axis formed by the combination of various time points, pointing from the time points that have passed to the time points that have not yet arrived. The fixed time length is the time length set by the staff to obtain the historical usage data of the water pump, such as three years. A fixed interval is established to facilitate the acquisition and analysis of data.

[0078] Step S501: Obtain the effective overall number of times each point is determined as a valid position point and the overall analysis number in a fixed interval.

[0079] The overall analysis times are the total number of times the water inlet pipe is moved horizontally in a fixed interval to identify each point as a valid position point, and the effective overall times are the total number of times a point is determined as a valid position point in the overall analysis times.

[0080] Step S502: Calculate based on the effective overall number and the overall analysis number to determine the effective overall ratio.

[0081] The effective overall proportion is the proportion of points determined as effective location points, which is determined by dividing the effective overall number by the overall analysis number.

[0082] Step S503: define points where the effective overall proportion is greater than the preset benchmark demand proportion as theoretically feasible points, and connect the theoretically feasible points in sequence to determine the pipeline movement path.

[0083] The benchmark demand ratio is the minimum effective overall ratio set by the staff to be determined that the point is often determined as a valid position point. When the effective overall ratio is greater than the benchmark demand ratio, it means that the point is currently located with a greater probability of being determined as a valid position point. At this time, it is determined as a theoretically feasible point, and the pipeline movement path is determined based on the theoretical feasible points, so that the detection interval distance at each theoretically feasible point can be determined; the method for connecting the theoretical feasible points can be random connection, or it can be connected according to the method of steps S600-S603, which will not be repeated here.

[0084] Reference Figure 6 , the steps of connecting each theoretical feasible point in sequence to determine the pipeline moving path include: Step S600: randomly selecting a theoretically feasible point from all theoretically feasible points and connecting it to the original position.

[0085] A theoretically feasible point is randomly selected from all the theoretically feasible points, and can be connected to the original position, so that the water inlet pipe is moved out of the original position to detect the theoretically feasible point.

[0086] Step S601: randomly selecting a theoretically feasible point from the remaining theoretically feasible points to connect with the previously selected theoretically feasible point, and continue selecting until there is no theoretically feasible point to select.

[0087] A theoretically feasible point is randomly selected from the remaining theoretically feasible points and connected to the previously determined theoretically feasible point, so that the water inlet pipeline can be moved to the new theoretically feasible point for detection after the previous theoretically feasible point detection is completed; the theoretically feasible points can be connected in sequence through continuous selection.

[0088] Step S602: Determine a feasible connected path based on the current theoretically feasible point connection status, and determine a feasible connected distance based on the feasible connected path.

[0089] A feasible connected path is the path obtained by connecting all theoretical feasible points from front to back, and the feasible connected distance is the total distance of the feasible connected path.

[0090] Step S603: Determine the feasible connected distance with the smallest value according to the sorting rule, and determine the feasible connected path corresponding to the feasible connected distance as the pipeline moving path.

[0091] The sorting rules can be used to determine the feasible connected distance with the smallest value, that is, the overall efficiency of the water inlet pipeline is the highest when it moves along the feasible connected path corresponding to the feasible connected distance. In this case, it can be defined as the pipeline movement path.

[0092] Reference Figure 7 After the feasible connected distance is determined, the water pump intelligent control method also includes: Step S700: Determine whether there are at least two feasible connected paths with the same minimum connected distance.

[0093] The purpose of the judgment is to find out whether there are multiple feasible connected paths that meet the requirements.

[0094] Step S7001: If there are not at least two feasible connected paths with the smallest and identical feasible connected distances, the pipeline moving path is determined according to the feasible connected path corresponding to the unique feasible connected distance with the smallest numerical value.

[0095] When there are not at least two feasible connected paths with the smallest and identical distances, it means that only one feasible connected path can be determined as the pipeline moving path, and the pipeline moving path can be determined normally.

[0096] Step S7002: If there are at least two feasible connected paths with the same minimum feasible connected distance, the feasible connected path corresponding to the feasible connected distance with the smallest value is defined as the alternative connected path, and the number of times each point on the alternative connected path is used as a demand location point is obtained in a fixed interval.

[0097] When there are at least two feasible connected paths with the same minimum connected distance, it means that there are multiple feasible connected paths that meet the requirements. At this time, they need to be screened; define alternative connected paths to distinguish different feasible connected paths for subsequent analysis; the number of requirements is the total number of times the points on the alternative connected paths are determined to be the required locations.

[0098] Step S701: define points whose demand times are not zero as permitted points, and count the permitted points on each candidate connected path to determine the permitted quantity.

[0099] Permit points are defined to distinguish points that may serve as demand locations, and the permitted quantity is the total quantity of all permitted points.

[0100] Step S702: determining the maximum permitted quantity according to the sorting rule, and determining the candidate connected paths corresponding to the permitted quantity as the pipeline moving paths.
