[0002] Pipeline sprinkling irrigation technology uses natural drop to send water to different fields through pressure pipeline, and the water is sprayed into the air through nozzle and then falls on the field, providing water for crop growth. Compared with traditional surface irrigation, sprinkling irrigation has higher uniformity and almost no surface runoff and deep seepage, so the utilization coefficient of irrigation water is higher, and the amount of water used to achieve the same irrigation effect is less, and the water-saving effect is more significant in drought areas.

[0003] When displaying irrigation area information using a water-saving monitoring visualization platform, the information of different nozzles can be displayed to facilitate real-time monitoring and abnormal management. Due to the influence of the topographic drop of the irrigation area and the pipeline arrangement, the water flow of the main waterway is blocked when it reaches each nozzle, resulting in different pressures of the nozzles, and the uniformity of nozzle irrigation decreases for different fields.

[0018] In order to further clarify the technical means and effects taken by the present application to achieve the predetermined inventive purpose, the specific implementation, structure, features and effects of the irrigation area information visualization method and system of a water-saving monitoring platform according to the present application are described in detail as follows in combination with the drawings and preferred embodiments. 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.

[0019] 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.

[0020] The specific scheme of the irrigation area information visualization method and system of a water-saving monitoring platform provided by the present application is specifically described below in combination with the drawings.

[0021] In the first aspect, refer to Figure 1 which shows the step flow chart of the irrigation area information visualization method of a water-saving monitoring platform provided by one embodiment of the present application, and the method comprises the following steps: 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 water road according to the relative position and height of the nozzle and the water storage pool.

[0022] It should be noted that the visualization platform can display the information of each field 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 uses natural drop to send water through the pressure pipeline to the nozzle of each field, the nozzle is affected by the topographic drop of the irrigation area and the pipeline arrangement mode in this process, so that the pressure through the main water road to each nozzle is different, resulting in that the irrigation efficiency of the nozzle is affected by the topographic height and the pipeline. Therefore, the present embodiment analyzes the topography and pipeline of each nozzle, and adjusts the pressure of the main water road to eliminate the influence of the topography and pipeline arrangement.

[0023] The present embodiment first reads the wind direction and wind speed at the current time by using the water-saving monitoring platform, and obtains the relative elevation and position of each nozzle on each main water road according to the relative position and height of the nozzle and the water storage pool.

[0024] 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 a wind speed and direction sensor in an Internet of Things device linked to the water-saving monitoring platform. Further, the specific way of obtaining the relative elevation and position of each nozzle on each main water road according to the relative position and height of the nozzle and the water storage pool is as follows: The height of the water storage tank is recorded as 0 elevation, and the elevation difference between each nozzle and the 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; It should be noted that each nozzle covers a field area in the irrigation area, and since the rotation of the nozzle is driven by the reaction force generated by the water spray, 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 nozzles 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.

[0025] Step S002, on each main waterway, analyze the relative elevation of the nozzles passed by when reaching each nozzle to reflect the consumption of water pressure and the arrangement of the nozzles passed by, and obtain the affected degree of each nozzle on each main waterway.

[0026] It should be noted that multiple nozzles are usually connected to the same main waterway during sprinkler irrigation. Due to the limitation of the field area on the sprinkler nozzle and the different heights of different field areas, the pressure of the water flow reaching each nozzle in the main waterway is different. Therefore, in this embodiment, the relative elevation of the nozzles passed by when reaching each nozzle is analyzed to reflect the consumption of water pressure and the arrangement of the nozzles passed by, and the affected degree of each nozzle on each main waterway is obtained.

[0027] Preferably, on each main waterway, the specific steps of analyzing the relative elevation of the nozzles passed by when reaching each nozzle to reflect the consumption of water pressure and the arrangement of the nozzles passed by, and obtaining the affected degree of each nozzle on each main waterway include: 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 passed before the main waterway; According to the arrangement of each nozzle on the main waterway, the kinetic energy loss parameter of each nozzle is obtained; According to the elevation influence parameter and the kinetic energy loss parameter, the affected degree of each nozzle on each main waterway is obtained.

[0028] 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 passed before the main waterway includes: The average of the relative elevations of all the nozzles passed by when reaching each nozzle on each main waterway is recorded as the cumulative relative elevation of each nozzle on each main waterway; The difference between the relative elevation of each nozzle on each main waterway and the cumulative relative elevation is recorded as the relative elevation difference of each nozzle on each main waterway; The relative elevation difference amplitude of all the nozzles on each main waterway is obtained, and the result of normalizing the relative elevation difference amplitude is recorded as the elevation influence parameter of each nozzle on each main waterway.

[0029] In an embodiment of the present application, the normalization of the relative elevation difference amplitude is performed by using a premnmx function to normalize the relative elevation difference amplitude to wherein the premnmx function is a known technique, and the embodiment will not be described in detail; since the difference in the relative elevation of each nozzle and the nozzles along the way is positive or negative, the normalization operation is performed by using the premnmx function.

[0030] 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 by the bending of the main waterway when arranging the main waterway to avoid the cultivation area of the field area, and when the high-speed water flow collides with the bending, the kinetic energy is lost, and the closer the distance between the current nozzle and the bending nozzle, the greater the kinetic energy loss.

[0031] Further, on each main waterway, the specific manner of obtaining the kinetic energy loss parameter of each nozzle according to the arrangement and bending of each nozzle on the main waterway is as follows: According to the position coordinates of each nozzle in all the main waterways and the relative elevation of each nozzle, a three-dimensional space of the field nozzle of each nozzle is constructed; wherein the three-dimensional space of the field nozzle 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. According to the positions of all the nozzles in the three-dimensional space of the field nozzle, the bending degree of each nozzle of each passing nozzle is obtained. According to the bending degree of each nozzle of each passing nozzle and the distance from the previous passing nozzle, the kinetic energy loss parameter of each nozzle is obtained.

[0032] Specifically, according to the positions of all the nozzles in the three-dimensional space of the field nozzle, the specific manner of obtaining the bending degree of each nozzle of each passing nozzle is as follows: All the nozzles passed by each nozzle in each main waterway are recorded as the passing nozzle of each nozzle in each main waterway. The positions of all the passing nozzles of each nozzle on each main waterway in the three-dimensional space of the field nozzle are fitted to obtain a main waterway fitting space line of each nozzle. The Euclidean distance between each passing nozzle of each nozzle and the main waterway fitting space line is recorded as the bending degree of each passing nozzle of each nozzle.

[0033] It should be noted that if the nozzle arrangement of each nozzle is a straight line, the kinetic energy loss will only be affected by the shunt of the passing nozzle, if the main waterway is more curved, that is, the Euclidean distance of each passing nozzle and the space line fitting the main waterway is larger, the kinetic energy loss of the water flow encountering the bending part is larger, so the bending degree is larger, and if there is a passing nozzle with extremely close distance and extremely large bending degree before the nozzle, the kinetic energy loss is larger because the water flow fails to recover kinetic energy through a long pipeline.

[0034] Further, the specific way of obtaining the kinetic energy loss parameter of each nozzle according to the bending degree of each passing nozzle of each nozzle and the distance from the previous passing nozzle is: Obtaining the kinetic energy loss parameter of each nozzle, the kinetic energy loss parameter is positively correlated with the bending degree of all passing nozzles of each nozzle, and is negatively correlated with the distance from the previous passing nozzle.

[0035] As an example, the calculation method of the kinetic energy loss parameter of the i-th nozzle is: Wherein, is the distance of the i-th nozzle from the j-th passing nozzle, is the bending degree of the j-th passing nozzle of the i-th nozzle; is the bending degree of the j-th passing nozzle of the i-th nozzle, wherein the j-th passing nozzle is the previous passing nozzle of the i-th nozzle, is the number of passing nozzles of the i-th nozzle. Specifically, according to the elevation influence parameter and the kinetic energy loss parameter, the specific way of obtaining the affected degree of each nozzle on each main waterway is: Obtaining the affected degree of each nozzle on each main waterway, the affected degree is positively proportional to the elevation influence parameter and the kinetic energy loss parameter. As an example, the embodiment multiplies the affected degree of each nozzle on each main waterway after linear normalization of the affected degree of each nozzle on each main waterway and the elevation influence parameter, and the result is taken as the affected degree of each nozzle on each main waterway.

[0036] It should be noted that the linear normalization of the embodiment is realized by using the maximum and minimum value normalization algorithm.

[0037] It should be noted that the linear normalization of the embodiment is realized by using the maximum and minimum value normalization algorithm.

[0038] It should be noted that the linear normalization of the embodiment is realized by using the maximum and minimum value normalization algorithm.

[0039] ​​Step S003, constructing a visualization plane of the irrigation area using the positions of all the nozzles on all the main water routes; on each main water route, using the visualization plane of the irrigation area to analyze the relative positions of each nozzle and adjacent nozzles in the wind direction at the current time, obtaining the upstream nozzle of each nozzle on each main water route; using the affected degree of the upstream nozzle in combination with the atomization under the wind speed at the current time, obtaining the atomization diffusion degree of each nozzle on each main water route by each upstream nozzle; according to the atomization diffusion degree and the diffusion of water mist under the influence of the relative elevation of different nozzles, obtaining the linkage affected degree of each nozzle on each main water route.

[0040] It should be noted that after obtaining the affected degree of each nozzle, the pressure output by the water storage tank can be adjusted to increase or decrease the pressure, thereby realizing the regulation and control of the sprinkling effect. However, since the sprinkling nozzles are distributed in a network and connected to each nozzle through the main water route, and the water pump pressure is usually output from the water storage tank to each main pipeline, that is, the self-adaptive pressure regulation of each nozzle cannot be realized. Therefore, when adjusting the pressure of a main water route, it cannot completely make each nozzle on the main water route achieve the optimal sprinkling effect.

[0041] In actual sprinkling scenarios, the water flow sprayed from the nozzle is affected by air resistance and water droplets, and if there is wind interference at this time, when the wind speed is too large, the pressure of the nozzle with a low affected degree is increased, the air resistance of the sprayed water flow is larger, and the water flow is atomized. The water droplets after atomization are scattered by the wind, and the landing point deviates from the landing point without wind, resulting in a decrease in the uniformity of sprinkling.

[0042] It should be further noted that the atomized water flow is more susceptible to wind, causing water droplets that should fall in the current nozzle corresponding field to fall into the field downstream of the wind direction. Therefore, the embodiment considers that too high pressure causes water flow to be atomized by wind resistance, resulting in landing point deviation, and the field corresponding to the nozzle with a large affected degree receives water flow from the nozzle with a small deviation degree, thereby balancing the water pressure of multiple main water routes, making the water flow landing point as uniform as possible in each field, and thereby improving the efficiency of sprinkling.

[0043] Preferably, a visualization plane of the irrigation area is constructed using the positions of all the nozzles on all the main water routes; on each main water route, the relative positions of each nozzle and adjacent nozzles in the wind direction at the current time are analyzed using the visualization plane of the irrigation area, and the specific way to obtain the upstream nozzle of each nozzle on each main water route is as follows: A two-dimensional visualization plane of the irrigation area is constructed according to the longitude and latitude, and the positions of all the nozzles on all the main water routes are projected onto the visualization plane of the irrigation area; For the jth main water route and the kth nozzle, the nozzles corresponding to the field edge tangent to the kth nozzle are recorded as adjacent nozzles of the kth nozzle. Let the current time be the 0 degree direction, the position of the kth nozzle as the origin, and the adjacent nozzles between 90 degrees and 270 degrees among all adjacent nozzles of the kth nozzle be the upstream nozzles of the kth nozzle.

[0044] It should be noted that the upstream nozzle and the kth nozzle are not necessarily on the same main waterway.

[0045] It should be noted that the smaller the affected degree of the upstream nozzle, the more the upstream nozzle is not affected by the terrain and the bending of the main waterway, and the greater the wind speed, the smaller the affected degree, and the more likely the water flow sprayed by the upstream nozzle is atomized and sprayed into the field of the current nozzle. Therefore, the atomization diffusion degree of each nozzle affected by each upstream nozzle is obtained by the affected degree of each upstream nozzle of each nozzle and the wind speed at the current time.

[0046] Preferably, the specific way of obtaining the atomization diffusion degree of each nozzle on each main waterway affected by each upstream nozzle of the nozzle is as follows: The atomization diffusion degree of each nozzle on each main waterway affected by each upstream nozzle of the nozzle 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.

[0047] As an example, the specific way of obtaining the atomization diffusion degree of the kth nozzle on the jth main waterway affected by the pth upstream nozzle of the nozzle is as follows: 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 on the jth main waterway affected by the pth upstream nozzle of the nozzle. It should be noted that if the affected degree of the pth upstream nozzle is 0, the atomization diffusion degree of the kth nozzle on the jth main waterway affected by the pth upstream nozzle of the nozzle is recorded as 1.

[0048] It should be noted that the diffusion of 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 its 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 by combining the atomization diffusion degree.

[0049] 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 water mist under the influence of the relative elevation of different nozzles are as follows: obtaining, according to the relative elevations of each nozzle and each upstream nozzle thereof, an elevation gain coefficient of each nozzle on each main waterway with respect to each upstream nozzle thereof; obtaining, according to the relative elevations of each nozzle and each upstream nozzle thereof, an elevation gain coefficient of each nozzle on each main waterway with respect to each upstream nozzle thereof; obtaining, according to the relative elevations of each nozzle and each upstream nozzle thereof, an elevation gain coefficient of each nozzle on each main waterway with respect to each upstream nozzle thereof;

[0050] Specifically, on each main waterway, the specific way of obtaining the elevation gain coefficient of each nozzle on each main waterway with respect to each upstream nozzle thereof according to the relative elevations of each nozzle and each upstream nozzle thereof is as follows: obtaining, according to the relative elevations of each nozzle and each upstream nozzle thereof, an elevation gain coefficient of each nozzle on each main waterway with respect to each upstream nozzle thereof; If the drift elongation parameter of the kth nozzle and the pth upstream nozzle thereof on the jth main waterway is equal to 0, the absolute value of the drift elongation parameter of the kth nozzle and the pth upstream nozzle thereof on the jth main waterway is recorded as the elevation gain coefficient of the kth nozzle on the jth main waterway with respect to the pth upstream nozzle thereof. If the drift elongation parameter of the kth nozzle and the pth upstream nozzle thereof on the jth main waterway is greater than 0, the elevation gain coefficient of the kth nozzle on the jth main waterway with respect to the pth upstream nozzle thereof is recorded as 1.

[0051] It is to be noted that if the kth nozzle is lower than the pth upstream nozzle, the kth nozzle is more likely to receive the water flow atomized by the pth upstream nozzle, and thus the elevation gain coefficient is smaller, which can be used to weaken the affected degree of the kth nozzle, i.e., to make the water flow missing of the kth nozzle available through increasing pressure or the atomized water flow of the pth upstream nozzle.

[0052] Further, the compensation weight of each nozzle on each main waterway with respect to each upstream nozzle thereof is obtained, and the compensation weight is inversely proportional to the elevation gain coefficient and the atomization diffusion degree; 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 waterway with respect to each upstream nozzle thereof is recorded as the compensation weight of each nozzle on each main waterway with respect to each upstream nozzle thereof.

[0053] Further, the specific way of compensating the affected degree of each nozzle on each main waterway with the compensation weight to obtain the linkage affected degree of each nozzle on each main waterway is as follows: The product of the sum of the compensation weights of all upstream nozzles for each nozzle on each main waterway and the degree of influence of each nozzle on each main waterway is recorded as the linkage influence degree of each nozzle on each main waterway.

[0054] It should be noted that since each nozzle is affected by the atomization diffusion of all upstream nozzles at the same time, this embodiment compensates the degree of influence of the current nozzle with the sum of the compensation weights of all upstream nozzles to obtain the degree of linkage influence of each nozzle on each main waterway.

[0055] Step S004: Use the degree of linkage influence to screen the missing water nozzles on each main waterway, and use the degree of atomization diffusion of the non-missing water nozzles affected by each upstream nozzle to obtain the balance adjustment coefficient of each main waterway; on the visual water-saving monitoring platform, use the balance adjustment coefficient to balance the water pressure of each main waterway.

[0056] It should be noted that after obtaining the degree of impact on the linkage of each nozzle on each main waterway, the greater the degree of impact, the larger the water gap of the nozzle and the inability to obtain the atomized and diffused water from the upstream nozzle; therefore, the more water-missing nozzles on a main waterway and the greater the degree of impact on the linkage of the missing water nozzles, the more the main waterway needs to increase the water pressure and water volume.

[0057] It should be further explained that since the pressure regulation of the main waterway is not only affected by the water gap in the current main waterway, but also by the demand for atomized diffusion water flow from the main waterway downstream of the wind direction, it is also necessary to avoid the current main waterway being affected by the supply of the main waterway upstream of the wind direction when the main waterway is downstream of the wind direction.

[0058] Preferably, the specific steps of screening the missing water nozzles on each main waterway using the linkage influence degree and obtaining the balance adjustment coefficient of each main waterway using the atomization diffusion degree of each upstream nozzle of the non-missing water nozzle include: Using the linkage impact degree, the missing water nozzles on each main waterway are screened, and an initial adjustment coefficient of each main waterway is obtained according to the linkage impact degree of the missing water nozzles; The initial adjustment coefficient is adjusted using the atomization diffusion degree when the non-missing water nozzle is used as the upstream nozzle to obtain the balanced adjustment coefficient of each main waterway.

[0059] Specifically, the linkage impact degree is used to screen the missing water nozzles on each main waterway, and the specific method of obtaining the initial adjustment coefficient of each main waterway according to the linkage impact degree of the missing water nozzles is as follows: In each main waterway, all nozzles whose linkage affected degree is greater than 0 are recorded as the missing water nozzles of each main waterway; Sum the affected degree of linkage of all missing water amount nozzles of each main water path, and mark it as the initial adjustment coefficient of each main water path.

[0060] Further, the initial adjustment coefficient is adjusted by using the atomization and diffusion degree of the non-missing water amount nozzle as the upstream nozzle, and the specific steps of obtaining the balanced adjustment coefficient of each main water path include: According to the number of non-missing water amount nozzles and the atomization and diffusion degree of the non-missing water amount nozzle as the upstream nozzle, a correction weight of each main water path is obtained. The initial adjustment coefficient is adjusted according to the correction weight, and the balanced adjustment coefficient of each main water path is obtained.

[0061] Specifically, the correction weight of each main water path is obtained according to the number of non-missing water amount nozzles and the atomization and diffusion degree of the non-missing water amount nozzle as the upstream nozzle, and the specific way is: The nozzles other than the missing water amount nozzles in each main water path are marked as non-missing water amount nozzles on each main water path. The ratio of the sum of the atomization and diffusion degrees of the non-missing water amount nozzles on each main water path as the upstream nozzle to the number of non-missing water amount nozzles on each main water path is normalized, and marked as the correction weight of each main water path. It should be noted that the ratio is normalized by using a sigmoid function in this embodiment, which limits the value of the correction weight to between; if the number of non-missing water amount nozzles on each main water path is 0, the correction weight of each main water path is marked as 0.

[0062] 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: The balanced adjustment coefficient of each main water path is obtained by multiplying the initial adjustment coefficient of each main water path by the sum of the correction weight of each main water path and 1.

[0063] It should be noted that after obtaining the balanced adjustment coefficient of each main water path, the water output of different main water paths can be pressurized by the pressurizing pump to balance each main water path.
