Description

Technical Field

[0001] This invention relates to the field of data processing technology, and specifically to a method and system for visualizing irrigation district information on a water-saving monitoring platform. Background Technology

[0002] Pipeline sprinkler irrigation technology utilizes natural elevation differences to deliver water through pressurized pipes to different fields. The water is then sprayed into the air through nozzles and falls onto the fields, providing moisture for crop growth. Compared to traditional surface irrigation, sprinkler irrigation offers higher uniformity and produces almost no surface runoff or deep seepage. It also boasts a higher water utilization coefficient, requiring less water to achieve the same irrigation effect, making it particularly effective for water conservation in arid and water-scarce regions.

[0003] When using a water-saving monitoring visualization platform to display irrigation district information, information on different nozzles can be shown, facilitating real-time monitoring and anomaly management. Because nozzles are affected by the terrain elevation differences and pipeline layout within the irrigation district, blockages can occur when water from the main waterway reaches each nozzle, resulting in varying nozzle pressures and reduced uniformity of irrigation across different fields.

[0026] Preferably, the specific obtaining step of the upstream nozzle comprises:

[0027] For the kth nozzle on the jth main waterway, the nozzles corresponding to the field edges tangent to the irrigation area corresponding to the kth nozzle are recorded as the adjacent nozzles of the kth nozzle;

[0048] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined invention purpose, the following will combine the drawings and the preferred embodiments to specifically describe the irrigation area information visualization method and system of the water-saving monitoring platform according to the present application, the specific implementation, structure, features and effects thereof, as follows. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0050] The specific scheme of the irrigation area information visualization method and system of the water-saving monitoring platform provided by the present application will be specifically described below in combination with the drawings.

[0051] In the first aspect, please refer to Figure 1It shows a step flow chart of a water-saving monitoring platform irrigation area information visualization method provided by an embodiment of the present application, and the method comprises the following steps:

[0052] Step S001, read the wind direction and wind speed at the current time by using the water-saving monitoring platform, and obtain the relative elevation and position of each nozzle on each main waterway according to the relative position and height of the nozzle and the water storage pool.

[0053] It should be noted that the visualization platform can display the information of each field area and its sprinkler nozzle in the irrigation area, which is used for monitoring and controlling the sprinkling area to prevent excessive irrigation or insufficient irrigation water, thereby avoiding waste of water resources; since the sprinkling technology is to use natural drop to send water to each nozzle of the field area through the pressure pipeline, the nozzle is affected by the topographic drop of the irrigation area and the pipeline arrangement mode in the process, so that the pressure through the main waterway to each nozzle is different, which causes the irrigation efficiency of the nozzle to be affected by the topographic height and the pipeline, therefore, in this embodiment, the affected nozzle is adjusted by adjusting the pressure of the main waterway to eliminate the influence of the topography and the pipeline arrangement.

[0054] Firstly, the wind direction and wind speed at the current time are read by using the water-saving monitoring platform, and the relative elevation and position of each nozzle on each main waterway are obtained according to the relative position and height of the nozzle and the water storage pool.

[0055] Specifically, the wind direction and wind speed at the current time are read by using the water-saving monitoring platform, wherein the wind direction and wind speed are obtained by the wind speed and direction sensor in the Internet of Things device linked to the water-saving monitoring platform;

[0056] Further, the specific way of obtaining the relative elevation and position of each nozzle on each main waterway according to the relative position and height of the nozzle and the water storage pool is as follows:

[0057] The height of the water storage pool is recorded as 0 elevation, and the difference between the elevation of each nozzle and 0 elevation is recorded as the relative elevation of each nozzle; the longitude and latitude of each nozzle in the irrigation area are recorded as the coordinates of the position of each nozzle;

[0058] It should be noted that each nozzle covers a field area in the irrigation area, since the rotation and spraying of the nozzle is driven by the reaction force generated by the water spraying, the field area that can be sprayed by the nozzle is circular, and the field areas corresponding to adjacent nozzles are tangent; in this embodiment, the combination mode of the nozzle is arranged in the form of a regular hexagon, and other embodiments can also be combined in the form of a square, a regular triangle, etc.

[0059] Step S002, on each main waterway, analyze the relative elevation of the nozzle on the way to each nozzle to reflect the water pressure consumption, and the arrangement and bending of the nozzle on the way, and obtain the affected degree of each nozzle on each main waterway.

[0060] It should be noted that, in the spray irrigation, usually a plurality of nozzles are connected to the same main waterway, due to the limitation of the field area for the spray irrigation nozzle and the different heights of different fields, the pressure of the water flow in the main waterway to each nozzle is different, therefore, the embodiment reflects the consumption of water pressure and the arrangement of the nozzle by analyzing the relative elevation of the nozzle when reaching each nozzle, and obtains the affected degree of each nozzle on each main waterway.

[0061] Preferably, the specific steps of analyzing the relative elevation of the nozzle when reaching each nozzle to reflect the consumption of water pressure and the arrangement of the nozzle on each main waterway to obtain the affected degree of each nozzle on each main waterway include:

[0062] On each main waterway, the elevation influence parameter of each nozzle is obtained according to the relative elevation difference between each nozzle and all the nozzles before the main waterway;

[0063] According to the arrangement of each nozzle on the main waterway, the kinetic energy loss parameter of each nozzle is obtained;

[0064] According to the elevation influence parameter and the kinetic energy loss parameter, the affected degree of each nozzle on each main waterway is obtained.

[0065] Specifically, on each main waterway, the specific way of obtaining the elevation influence parameter of each nozzle according to the relative elevation difference between each nozzle and all the nozzles before the main waterway includes:

[0066] The average of the relative elevations of all the nozzles reached by each nozzle on each main waterway is recorded as the relative elevation of each nozzle on each main waterway;

[0067] The difference between the relative elevation of each nozzle on each main waterway and the relative elevation is recorded as the relative elevation difference of each nozzle on each main waterway;

[0068] The relative elevation difference of all the nozzles on each main waterway is obtained, and the result of the normalization of the relative elevation difference is recorded as the elevation influence parameter of each nozzle on each main waterway.

[0069] In an embodiment of the present application, the way of normalizing the relative elevation difference is to normalize the relative elevation difference to between using the prenmx function; wherein the prenmx function is a known technology, and the embodiment will not be described again; since the difference between each nozzle and the relative elevation of the nozzle it passes is positive or negative, the prenmx function is used for normalization operation.

[0070] It should be noted that the pressure of the water flow of the main waterway when reaching the nozzle is not only affected by the relative elevation, but also due to the bending of the main waterway when arranging the main waterway to avoid the cultivation area of the field area, when the high-speed water flow collides with the bending, the kinetic energy is lost, and the closer the distance from the current nozzle, the greater the kinetic energy loss of the bending nozzle.

[0071] Further, on each main waterway, according to the arrangement bending of each nozzle on the main waterway, the specific way of obtaining the kinetic energy loss parameter of each nozzle is:

[0072] According to the position coordinates of each nozzle in all main waterways and the relative elevation of each nozzle, a field nozzle three-dimensional space of each nozzle is constructed; wherein the field nozzle three-dimensional space is a three-dimensional space, the Y axis is the longitude of the nozzle, the X axis is the latitude of the nozzle, and the Z axis is the relative elevation of the nozzle;

[0073] According to the positions of all nozzles in the field nozzle three-dimensional space, the bending degree of each nozzle of each path nozzle is obtained.

[0074] According to the bending degree of each path nozzle of each nozzle and the distance from the previous path nozzle, the kinetic energy loss parameter of each nozzle is obtained.

[0075] Specifically, according to the positions of all nozzles in the field nozzle three-dimensional space, the specific way of obtaining the bending degree of each path nozzle of each nozzle is:

[0076] All nozzles passed by each nozzle in each main waterway are recorded as the path nozzles of each nozzle in each main waterway;

[0077] The positions of all path nozzles of each nozzle on each main waterway are fitted in the field nozzle three-dimensional space to obtain a main waterway fitting space line of each nozzle.

[0078] The Euclidean distance between each path nozzle of each nozzle and the main waterway fitting space line is recorded as the bending degree of each path nozzle of each nozzle.

[0079] It should be noted that if the nozzles passed by each nozzle are arranged in a straight line, the kinetic energy loss will only be affected by the diversion of the path nozzles, if the main waterway is more curved, that is, the Euclidean distance between each path nozzle and the main waterway fitting space line is larger, the kinetic energy loss of the water flow encountering the bending is larger, so the bending degree is larger, and if there is a path nozzle with extremely close distance and extremely large bending degree before the nozzle, the kinetic energy loss is larger because the water flow cannot recover the kinetic energy through a long pipeline.

[0080] Further, the specific way of obtaining the kinetic energy loss parameter of each nozzle according to the bending degree of each path nozzle of each nozzle and the distance from the previous path nozzle is:

[0081] An energy loss parameter of each nozzle is obtained, which is positively correlated with the bending degree of all the way nozzles of each nozzle and negatively correlated with the distance of each nozzle from the previous way nozzle.

[0082] As an example, the energy loss parameter of the i-th nozzle is calculated in the following manner:

[0083]

[0084] wherein, is the distance of the i-th nozzle from the j-th way nozzle, is the bending degree of the j-th way nozzle of the i-th nozzle; is the bending degree of the j-th way nozzle of the i-th nozzle, wherein the j-th way nozzle is the previous way nozzle of the i-th nozzle, is the number of way nozzles of the i-th nozzle. Specifically, the specific manner of obtaining the affected degree of each nozzle on each main waterway according to the elevation influence parameter and the energy loss parameter is as follows: The affected degree of each nozzle on each main waterway is obtained, which is positively proportional to the elevation influence parameter and the energy loss parameter.

[0085] As an example, the affected degree of each nozzle on each main waterway is multiplied by the linearly normalized result of the elevation influence parameter, and the result is taken as the affected degree of each nozzle on each main waterway.

[0086] It is to be noted that the linear normalization in the embodiment is realized by using the maximum and minimum value normalization algorithm.

[0087] Step S003, a visualization plane of the irrigation area is constructed using the positions of all the nozzles on all the main waterways; on each main waterway, the relative positions of each nozzle and adjacent nozzles in the wind direction at the current time are analyzed by using the visualization plane of the irrigation area to obtain the upstream nozzles of each nozzle on each main waterway; the affected degree of the upstream nozzles is combined with the atomization condition under the wind speed at the current time to obtain the atomization and diffusion degree of each nozzle on each main waterway caused by each upstream nozzle; and the linkage affected degree of each nozzle on each main waterway is obtained according to the atomization and diffusion degree and the diffusion condition of the water mist under the relative elevation influence of different nozzles.

[0088] It is to be noted that the linear normalization in the embodiment is realized by using the maximum and minimum value normalization algorithm.

[0089] Step S003, a visualization plane of the irrigation area is constructed using the positions of all the nozzles on all the main waterways; on each main waterway, the relative positions of each nozzle and adjacent nozzles in the wind direction at the current time are analyzed by using the visualization plane of the irrigation area to obtain the upstream nozzles of each nozzle on each main waterway; the affected degree of the upstream nozzles is combined with the atomization condition under the wind speed at the current time to obtain the atomization and diffusion degree of each nozzle on each main waterway caused by each upstream nozzle; and the linkage affected degree of each nozzle on each main waterway is obtained according to the atomization and diffusion degree and the diffusion condition of the water mist under the relative elevation influence of different nozzles.

[0090] ​​It should be noted that after the affected degree of each nozzle is obtained, the pressure output of the water storage pool can be adjusted to increase or decrease the pressure, thereby realizing the regulation of the sprinkling effect, but since the sprinkling nozzles are distributed in a network and connected to each other through the main waterways, and the water pump pressure is usually output from the water storage pool to each main pipeline, that is, the self-adaptive pressure regulation of each nozzle cannot be realized, so when the pressure of a main waterway is adjusted, it cannot completely make each nozzle on the main waterway achieve the optimal sprinkling effect.

[0091] However, in an actual sprinkling scenario, the water flow sprayed from the nozzle is affected by air resistance and is atomized, and if there is wind interference at this time, when the wind speed is too large, the pressure of a single main waterway is increased, the pressure of the nozzle with a low affected degree is increased, the air resistance of the sprayed water flow is increased, and the atomized water droplets are scattered with the wind, the landing point is deviated from the landing point without wind, and the sprinkling uniformity is reduced.

[0092] It should be further noted that the atomized water flow is more susceptible to wind, so that the water droplets that should fall in the current nozzle corresponding field fall into the field downstream of the wind direction, and therefore the embodiment considers that the high pressure causes the water flow to be atomized by wind resistance, resulting in a deviation of the landing point, and the field corresponding to the nozzle with a large affected degree receives the water flow of the nozzle with a small deviation degree, thereby balancing the water pressure of multiple main waterways, making the water flow landing point as uniform as possible in each field, and thereby improving the efficiency of sprinkling.

[0093] Preferably, a field visualization plane is constructed using the positions of all nozzles on all main waterways; on each main waterway, the relative positions of each nozzle and adjacent nozzles in the current time wind direction are analyzed using the field visualization plane, and the specific way to obtain the upstream nozzle of each nozzle on each main waterway is as follows:

[0094] A two-dimensional field visualization plane is constructed according to the longitude and latitude, and the positions of all nozzles on all main waterways are projected onto the field visualization plane;

[0095] For the kth nozzle on the jth main waterway, the nozzles corresponding to the field edge tangent to the kth nozzle are recorded as the adjacent nozzles of the kth nozzle;

[0096] The current time is recorded as the 0-degree direction, the position of the kth nozzle is taken as the origin, and the adjacent nozzles of the kth nozzle between 90 degrees and 270 degrees are recorded as the upstream nozzles of the kth nozzle.

[0097] It should be noted that the upstream nozzle and the kth nozzle are not necessarily on the same main waterway.

[0098] It should be noted that the smaller the affected degree of the upstream nozzle, the less affected the upstream nozzle is by the terrain and the bending of the main waterway, and the greater the wind speed, the more likely the water flow sprayed by the upstream nozzle is atomized and sprayed into the field of the current nozzle, so the affected degree of each nozzle by each upstream nozzle and the wind speed are used to obtain the atomization diffusion degree of each nozzle by each upstream nozzle.

[0099] Preferably, the specific way of obtaining the atomization diffusion degree of each nozzle by each upstream nozzle on each main waterway is as follows:

[0100] The atomization diffusion degree of each nozzle by each upstream nozzle on each main waterway is negatively correlated with the affected degree of each upstream nozzle of each nozzle and positively correlated with the wind speed at the current time.

[0101] As an example, the specific way of obtaining the atomization diffusion degree of the kth nozzle by the pth upstream nozzle on the jth main waterway is as follows:

[0102] The ratio of the wind speed at the current time to the affected degree of the pth upstream nozzle is recorded as the atomization diffusion degree of the kth nozzle by the pth upstream nozzle on the jth main waterway.

[0103] It should be noted that if the affected degree of the pth upstream nozzle is 0, the atomization diffusion degree of the kth nozzle by the pth upstream nozzle on the jth main waterway is recorded as 1.

[0104] It should be noted that the diffusion of the atomized water droplets is not only affected by the wind speed but also by the relative elevation of the corresponding field of different nozzles. Since the atomized water droplets are falling, if the current nozzle is lower than the upstream nozzle, the atomized water droplets will fall for a longer time and a longer distance in the air, so the number of falling water droplets is greater. Based on the above logic, the linkage affected degree of each nozzle on each main waterway is obtained based on the atomization diffusion degree.

[0105] Preferably, the specific steps of obtaining the linkage affected degree of each nozzle on each main waterway according to the atomization diffusion degree and the diffusion of the water mist under the influence of the relative elevation of different nozzles are as follows:

[0106] On each main waterway, the elevation gain coefficient of each nozzle by each upstream nozzle on each main waterway is obtained according to the relative elevation of each nozzle and each upstream nozzle thereof.

[0107] The compensation weight of each nozzle by each upstream nozzle on each main waterway is obtained according to the elevation gain coefficient and the atomization diffusion degree.

[0108] Compensate the affected degree of each nozzle on each main water path by the compensation weight, and obtain the linkage affected degree of each nozzle on each main water path.

[0109] Specifically, on each main water path, according to the relative elevation of each nozzle and each upstream nozzle thereof, the specific way of obtaining the elevation gain coefficient of each nozzle on each main water path by each upstream nozzle thereof is that:

[0110] Obtain the difference of the relative elevation of each nozzle and each upstream nozzle thereof on all main water paths, and after the maximum and minimum value normalization of the difference of the relative elevation, obtain the drift extension parameter of each nozzle and each upstream nozzle thereof;

[0111] If the drift extension parameter of the kth nozzle and the pth upstream nozzle thereof on the jth main water path is equal to 0, the absolute value of the drift extension parameter of the kth nozzle and the pth upstream nozzle thereof on the jth main water path is recorded as the elevation gain coefficient of the kth nozzle on the jth main water path by the pth upstream nozzle thereof. If the drift extension parameter of the kth nozzle and the pth upstream nozzle thereof on the jth main water path is greater than 0, the elevation gain coefficient of the kth nozzle on the jth main water path by the pth upstream nozzle thereof is recorded as 1.

[0112] It is required to be explained that if the kth nozzle is lower than the pth upstream nozzle, the kth nozzle is more likely to receive the atomized water flow of the pth upstream nozzle, and therefore the elevation gain coefficient is smaller, which can be used to weaken the affected degree of the kth nozzle, that is, to make the water flow missing of the kth nozzle can be obtained by increasing the pressure and also by the atomized water flow of the pth upstream nozzle.

[0113] Further, obtain the compensation weight of each nozzle on each main water path by each upstream nozzle thereof, which is inversely proportional to the elevation gain coefficient and the atomization diffusion degree;

[0114] As an example, the difference between 1 and the product of the atomization diffusion degree and the elevation gain coefficient of each nozzle on each main water path by each upstream nozzle thereof is recorded as the compensation weight of each nozzle on each main water path by each upstream nozzle thereof.

[0115] Further, the specific way of compensating the affected degree of each nozzle on each main water path by the compensation weight to obtain the linkage affected degree of each nozzle on each main water path is that:

[0116] The product of the sum of the compensation weight of each nozzle on each main water path by all upstream nozzles thereof and the affected degree of each nozzle on each main water path is recorded as the linkage affected degree of each nozzle on each main water path.

[0117] It is to be noted that, since each nozzle is simultaneously affected by the atomization diffusion of all upstream nozzles, the present embodiment compensates the affected degree of the current nozzle by the sum of the compensation weights of all upstream nozzles, to obtain the linkage affected degree of each nozzle on each main waterway.

[0118] Step S004, screening the missing water amount nozzles on each main waterway by the linkage affected degree, and obtaining the equilibrium adjustment coefficient of each main waterway by the atomization diffusion degree of each upstream nozzle of the non-missing water amount nozzle; using the equilibrium adjustment coefficient to balance the water pressure of each main waterway on the visual water saving monitoring platform.

[0119] It is to be noted that, after obtaining the linkage affected degree of each nozzle on each main waterway, the greater the affected degree, the greater the water amount gap of the nozzle and the water amount that cannot be obtained from the atomization diffusion of the upstream nozzle; therefore, the more the missing water amount nozzles on a main waterway, and the greater the linkage affected degree of the missing water amount nozzles, the greater the water pressure required by the main waterway to increase the water amount.

[0120] It is to be further noted that, since the pressure regulation of the main waterway is not only affected by the water amount gap of the current main waterway, but also affected by the demand of the main waterway downstream of the wind direction for the atomization diffusion water flow, it is also necessary to avoid the influence of the main waterway upstream of the wind direction on the current main waterway when the wind direction is downstream.

[0121] Preferably, the specific steps of screening the missing water amount nozzles on each main waterway by the linkage affected degree, and obtaining the equilibrium adjustment coefficient of each main waterway by the atomization diffusion degree of each upstream nozzle of the non-missing water amount nozzle include:

[0122] screening the missing water amount nozzles on each main waterway by the linkage affected degree, and obtaining the initial adjustment coefficient of each main waterway according to the linkage affected degree of the missing water amount nozzle;

[0123] adjusting the initial adjustment coefficient by the atomization diffusion degree of the non-missing water amount nozzle as the upstream nozzle, to obtain the equilibrium adjustment coefficient of each main waterway.

[0124] Specifically, the specific way of screening the missing water amount nozzles on each main waterway by the linkage affected degree, and obtaining the initial adjustment coefficient of each main waterway according to the linkage affected degree of the missing water amount nozzle includes:

[0125] on each main waterway, all nozzles with a linkage affected degree greater than 0 are recorded as the missing water amount nozzles of each main waterway;

[0126] the sum of the linkage affected degrees of all missing water amount nozzles of each main waterway is recorded as the initial adjustment coefficient of each main waterway.

[0127] Further, the specific steps of adjusting the initial adjustment coefficient according to the atomization diffusion degree of the non-missing water volume nozzle as the upstream nozzle to obtain the balanced adjustment coefficient of each main water path include:

[0128] According to the number of non-missing water volume nozzles and the atomization diffusion degree of the non-missing water volume nozzle as the upstream nozzle, the correction weight of each main water path is obtained.

[0129] According to the correction weight, the initial adjustment coefficient is adjusted to obtain the balanced adjustment coefficient of each main water path.

[0130] Specifically, the specific way of obtaining the correction weight of each main water path according to the number of non-missing water volume nozzles and the atomization diffusion degree of the non-missing water volume nozzle as the upstream nozzle is:

[0131] The nozzles other than the missing water volume nozzles in each main water path are recorded as the non-missing water volume nozzles on each main water path.

[0132] The ratio of the sum of the atomization diffusion degrees of the non-missing water volume nozzles as the upstream nozzle to the number of non-missing water volume nozzles on each main water path is normalized to obtain the correction weight of each main water path.

[0133] It should be noted that the ratio is normalized by using a sigmoid function in this embodiment to limit the value of the correction weight to between; if the number of non-missing water volume nozzles on each main water path is 0, the correction weight of each main water path is recorded as 0.

[0134] Further, the specific way of adjusting the initial adjustment coefficient according to the correction weight to obtain the balanced adjustment coefficient of each main water path is:

[0135] The sum of the correction weight of each main water path and 1 is multiplied by the initial adjustment coefficient of each main water path to obtain the balanced adjustment coefficient of each main water path.

[0136] It should be noted that after obtaining the balanced adjustment coefficient of each main water path, the water outlet of different main water paths can be pressurized by a pressurizing water pump to balance each main water path.

[0137] Preferably, the specific way of balancing the water pressure of each main water path using the balanced adjustment coefficient in the visual water-saving monitoring platform is:

[0138] The balanced adjustment coefficient of each main water path is input into the visual water-saving monitoring platform, and the pressurizing water pump of each main water path is adjusted in relative amplitude according to the balanced adjustment coefficient of each main water path.
