[0033] Combination Figure 1-2 , introduces a sprinkler irrigation control system provided by an embodiment of the present application, the system comprising:

[0034] The map collection unit is configured to collect information about a target area; the target area is an area to be irrigated, and the target area may be an area with a regular shape or an irregular shape.

[0035] The sprinkler irrigation execution unit includes a nozzle and a water flow driving unit, wherein the pitch angle and rotation angle of the nozzle are adjustable; specifically, the water flow driving unit is used to drive the water flow to spray out from the nozzle, thereby forming a water curtain.

[0036] The sprinkler irrigation control unit is configured to control the sprinkler irrigation execution unit to sprinkle irrigation on the target area based on the collected target area information.

[0037] In the embodiment of the present application, the water flow driving unit may be a water pump; the driving force of the water flow driving unit affects the impact force of the water flow sprayed by the nozzle and the water flow coverage distance.

[0038] In the embodiments of the present application, the pitch angle of the nozzle is different, the height of the water flow sprayed by the nozzle and the water flow coverage distance are different; the rotation angle of the nozzle is different, the direction of the water flow sprayed by the nozzle is different.

[0039] In the embodiment of the present application, by setting the sprinkler execution unit to have adjustable pitch angle and rotation angle, and setting a map collection unit and a sprinkler control unit at the same time, the sprinkler control unit controls the pitch angle and rotation angle of the sprinkler execution unit based on the collected information of the target area, so that the entire area to be irrigated in the target area can be evenly covered, automatic sampling and irrigation can be achieved, and the irrigation uniformity and accuracy of the target area can be improved.

[0040] In an embodiment of the present application, the target area information includes boundary information of the target area, relative position information between the sprinkler execution unit and the target area, and control parameter information corresponding to the boundary information; specifically, the boundary information of the target area represents the shape of the target area, and the relative position information between the sprinkler execution unit and the target area represents the working starting position point of the sprinkler execution unit; the control parameter information corresponding to the boundary information represents parameters such as the pitch angle and rotation angle required by the sprinkler execution unit when covering the target area to be irrigated.

[0041] In an embodiment of the present application, by collecting boundary information of the target area, relative position information between the sprinkler execution unit and the target area, and control parameter information corresponding to the boundary information, the control accuracy of the sprinkler execution unit is improved, and automatic sampling and irrigation are realized, thereby improving the irrigation uniformity and accuracy of the target area.

[0042] In an embodiment of the present application, the boundary information of the target area includes multiple target sprinkler points; the sprinkler control unit includes: a sprinkler strategy generation unit, which is configured to make predictions based on the control parameter information corresponding to the multiple target sprinkler points, and determine the control parameter information between adjacent target sprinkler points.

[0043] In an embodiment of the present application, a plurality of target sprinkler irrigation points are connected to form a boundary of a target area; the plurality of target sprinkler irrigation points each correspond to a set of control angles, and each set of control angles includes a pitch angle and a rotation angle.

[0044] In an embodiment of the present application, the sprinkler irrigation strategy generation unit may determine the control parameter information between adjacent target sprinkler irrigation points by interpolation.

[0045] In a specific embodiment of the present application, the multiple target sprinkler points include a first sprinkler point and a second sprinkler point, and the sprinkler strategy generation unit performs interpolation prediction based on the control parameter information corresponding to the first sprinkler point and the second sprinkler point, and determines the control parameter information corresponding to the third sprinkler point; wherein the third sprinkler point is a point on the connecting line between the first sprinkler point and the second sprinkler point; specifically, the third sprinkler point can be one point or multiple points.

[0046] In a specific embodiment of the present application, the distance between adjacent sprinkler points, including the third sprinkler point, is within a preset distance range. For example, the distance between the first sprinkler point and the second sprinkler point is 15m, and the preset distance range is 4-5m. At this time, two third sprinkler points should be inserted between the first sprinkler point and the second sprinkler point.

[0047] In a specific embodiment of the present application, the sprinkler strategy generation unit is also used to determine the third sprinkler point as the target sprinkler point, so that the sprinkler strategy generation unit predicts the control parameters between the first sprinkler point and the third sprinkler point and between the second sprinkler point and the third sprinkler point.

[0048] In a specific embodiment of the present application, the sprinkler strategy generation unit can also input the control parameter information corresponding to multiple target sprinkler points into the prediction learning model for prediction, and obtain the control parameter information between adjacent target sprinkler points; wherein the prediction learning model is obtained based on the control parameters corresponding to multiple sample sprinkler points for prediction learning.

[0049] In a specific embodiment of the present application, the sprinkler strategy generation unit is also configured to screen the third sprinkler points when there are multiple third sprinkler points, so that the angle difference between the rotation angles corresponding to adjacent sprinkler points is greater than the first preset angle and less than the second preset angle.

[0050] refer to Figure 3 In a specific embodiment of the present application, it is assumed that multiple target sprinkler points are pose1, pose2, pose3 and pose4. At this time, the sprinkler strategy generation unit predicts the sprinkler points between pose1 and pose2, between pose2 and pose3, and between pose3 and pose4 to obtain multiple third sprinkler points; specifically, 3 points are predicted between pose1 and pose2, 5 points are predicted between pose2 and pose3, and 3 points are predicted between pose3 and pose4.

[0051] refer to Figure 4 , when the difference in rotation angles between adjacent sprinkler points is greater than the first preset angle and less than the second preset angle, multiple third sprinkler points are screened to obtain control sprinkler points corresponding to the boundary of the target area; specifically, an intermediate point is reserved from three points between pose1 and pose2, two points are reserved from five points between pose2 and pose3, there is a screened point between the two points, and an intermediate point is reserved from three points between pose3 and pose4 to meet the above conditions.

[0052] In the embodiment of the present application, the control parameter information includes the pitch angle of the nozzle, the rotation angle of the nozzle, and the output water flow rate corresponding to the water flow driving unit.

[0053] In the embodiment of the present application, the output water flow rate corresponding to the water flow driving unit represents the impact force of the water flow. The greater the output water flow rate, the higher the stability of the spray water curtain of the nozzle and the greater the impact force of the water flow; conversely, the smaller the output water flow rate, the lower the stability of the spray water curtain; the impact force of the water flow will affect the water flow coverage distance and the impact force on the irrigated ground.

[0054] In a specific embodiment of the present application, the output water flow rates corresponding to different target sprinkler irrigation points may be different, or the output water flow rates corresponding to different target sprinkler irrigation points may be the same.

When the pitch angle is low, the irrigation ground will not be damaged, thereby improving the irrigation reliability and irrigation accuracy.

[0063] In an embodiment of the present application, the sprinkler irrigation strategy generation unit is configured to maintain the pitch angle at 10-15° and adjust the output water flow rate to adjust the maximum sprinkler irrigation distance when the maximum sprinkler irrigation distance is within the second interval, wherein the second interval is the space excluding the first interval in a circle with the sprinkler irrigation execution unit as the center and the second preset distance as the radius, wherein the second preset distance is greater than the first preset distance.

[0070] In a specific embodiment of the present application, when the maximum distance of sprinkler irrigation is within the third interval, the output water flow rate is maintained at the maximum water flow rate.

[0072] In a specific embodiment of the present application, when the maximum distance of the sprinkler irrigation is within the third interval, the adjustment range of the pitch angle is 10 to 25 degrees.

[0073] In an embodiment of the present application, by maintaining the output water flow at a larger water flow rate when the maximum distance of sprinkler irrigation is within the third interval, and adjusting the maximum distance of sprinkler irrigation by adjusting the pitch angle, it is ensured that the water curtain for long-distance irrigation has better wind resistance, thereby improving the reliability and accuracy of irrigation.
