[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Figure 1 This is a general flow chart of an irrigation area water intelligent dispatching method and system. In an embodiment of the present invention, an irrigation area water intelligent dispatching method includes: In Example 1, Figure 1 The implementation process of the intelligent water dispatching method for irrigation areas provided by the embodiment of the present invention is shown and described in detail below: S100: Obtain a river distribution network diagram within the irrigation area, mark the rivers and irrigation areas, wherein the rivers include: main streams and tributaries, divide the irrigation area into several slices, wherein each slice corresponds to a main stream or a tributary, and configure the corresponding relationship between the slices and the users.

[0027] In the river distribution network diagram, the rivers and the ranges that the rivers can irrigate are marked, and the irrigation range is divided into multiple slices; in other words, each slice corresponds to an irrigation area, and each irrigation area corresponds to at least one river; in this process, the slice can be simply understood as a field or several fields; the correspondence between the slice and the user is configured, and the correspondence is determined by the actual use of the land.

[0028] S200: Create a resource scheduling tree consisting of a main node, branch nodes and leaf nodes, and map the river distribution network diagram to the resource scheduling tree, obtain the water use scheduling authority of the river, and issue it to the resource scheduling tree.

[0029] A resource scheduling tree is created using main nodes, branch nodes and leaf nodes. The main node is equivalent to the "trunk", which is used to characterize the water resource distribution of the main stream. The branch node is equivalent to the "branch connected to the trunk", which is mainly used to characterize the water resource distribution of the tributary. The leaf node is equivalent to the "leaves connected to the branch". There are multiple leaf nodes under a branch node, and the leaf node is used to intuitively display soil moisture. The river distribution network diagram is mapped to the resource scheduling tree, that is, the resource scheduling tree is used to display the water use of rivers and soil in the irrigation area.

[0030] The water use scheduling authority of the river is issued to the resource scheduling tree; in real life, large-scale scheduling of water resources in irrigation areas should be coordinated by professional departments, but small-scale water resource scheduling can be carried out independently according to actual conditions; the advantage of issuing water use scheduling authority to the resource scheduling tree is that when it is monitored that the soil moisture is low and the growth of crops is restricted, water resources can be scheduled in a timely and effective manner to ensure the normal operation of agricultural production.

[0031] S300: Receive soil moisture data uploaded by the user, obtain the properties of the crops planted in each slice, find out the nodes with water demand, define them as target nodes, and use the pre-acquired weather monitoring data to calibrate the target nodes.

[0032] Receive soil moisture data uploaded by users and determine the crops planted in each slice and their attributes, including drought resistance, growth stage, and economic value of crops. According to the soil moisture data and attributes, find the nodes with water demand and define them as target nodes. Use weather data to calibrate the target nodes.

[0033] For example, users take photos of the soil through mobile terminals and determine the soil moisture level through deep learning models or machine learning algorithms. The moisture level can be divided into no drought, mild drought, moderate drought and severe drought, etc. Then determine the type and growth conditions of crops planted in the corresponding field and judge whether the field is short of water. If there is a shortage of water, the corresponding leaf node is determined as the target node.

[0034] S400: Construct a hierarchy of stepped water scheduling and transfer the hierarchy to the bottom of the resource scheduling tree, wherein the hierarchy includes at least: mild, moderate, severe and extreme, configure scheduling strategies of different levels, update the target node based on a preset frequency, set the push and pop steps of the target node in the hierarchy, trigger the start of the scheduling strategy, and perform water scheduling on the irrigation area.

[0035] Create multiple levels, each of which is distributed in a stepped manner, and transfer all these levels to the bottom of the resource scheduling tree; when the target node is found, transfer the target node to the level corresponding to the light level, trigger the start of the scheduling strategy, and perform preliminary processing on the target node; after the processing is completed, collect the soil moisture data in the target node again at the preset frequency and update the target node; if after the update, it is found that the soil moisture data is further reduced, that is, the soil is getting drier and drier, at this time, push the target node to the level corresponding to the moderate level and start the corresponding scheduling strategy; and so on, until the soil moisture data gradually increases, the target node is popped out of the level, the scheduling strategy is suspended, and the scheduling of water use in the irrigation area is completed.

[0036] The implementation process of the intelligent scheduling method for irrigation area water use provided by the embodiment of the present invention is as follows: In the level corresponding to the light level, when the target node is pushed in, the river distribution network diagram is traversed to find the water supply fields, build the dispatching waterway, and push it to the user; At the level corresponding to the moderate level, the water use scheduling authority is obtained to perform water scheduling for the irrigation area; In the level corresponding to the severity, the water use scheduling authority is revoked, the location of the target node is obtained, the location, soil moisture data and attributes are integrated, a monitoring report is generated, and the monitoring report is sent to a preset terminal; In the level corresponding to the extreme point, the main node or branch node is marked as the starting point of the scheduling waterway, the scheduling waterway is adjusted, and the control facilities are deployed.

[0037] After the target node is determined, the target node is pushed into the light level; find out the fields in the irrigation area that are rich in water resources and can supply water to the target node, and define them as water supply fields; build a scheduling waterway between the water supply field and the target node, and push the scheduling waterway to the user; the user enables the scheduling waterway to supply water to the target node, thereby realizing the transfer and scheduling of water resources within the slice; in other words, if the soil of only a single slice is dry, irrigation can be carried out by scheduling water resources in other slices.

[0038] The target node is updated at a preset frequency. If the analysis of soil photos uploaded by users shows that the soil drought has further intensified, the target node will be pushed from the mild level to the moderate level, and water scheduling authority will be opened to transport water to the irrigation area by adjusting the gates and pumping stations in the river.

[0039] After delivering water to the irrigation area, if the soil drought situation continues to worsen, small-scale water resource scheduling should be stopped and water scheduling authority should be withdrawn; because a large-scale drought may have occurred at this time; use the location, soil moisture data and attributes of the target node to generate a monitoring report, and send this monitoring report to the preset terminal, where the preset terminal should be the management department terminal.

[0040] If the drought situation at the target node continues to worsen after large-scale water resource scheduling, a scheduling waterway should be directly established between the river and the target node, and water conservancy facilities such as pumping stations and culverts should be used to irrigate the target node.

[0041] In Example 2, Figure 2 The implementation process of the intelligent water dispatching method for irrigation areas provided by the embodiment of the present invention is shown. The “dividing the irrigation range” is described in detail below: S101: Collect the idle areas in the irrigation area, determine the irrigation range of each river, and delete the idle areas from the irrigation range.

[0042] Find the idle areas in the irrigation area, that is, the areas where crops are not planted, and delete the idle areas from the irrigation range.

[0043] S102: Mark the direction of the river, and sort the slices according to the direction.

[0044] Determine the direction of the river, and sort the leaf nodes in the branch nodes according to the direction. By sorting the leaf nodes, the irrigation range corresponding to each river can be intuitively displayed.

[0045] In Example 3, different from Example 1, in this embodiment of the present invention, the method further includes: Collecting hydrological data of the river, wherein the hydrological data at least includes: water flow, water level and flow, and classifying the hydrological data corresponding to the main stream into a main node, and classifying the hydrological data corresponding to the tributary into a branch node; The branch node is mounted to the main node, the leaf node is mounted to the branch node, and the main node, branch node and leaf node are integrated to generate a resource scheduling tree.

[0046] Collect the hydrological data of the river and classify it into the corresponding branch node or leaf node; in this embodiment, the node is the basic unit of the resource scheduling tree, which is mainly used to store hydrological data and intuitively display the distribution of rivers. The main node and branch node also integrate water scheduling authority. By using the corresponding main node and branch node, the water flow control equipment in the corresponding river can be turned on or off, where the water flow control equipment is a pump station and a gate.

[0047] In Example 4, Figure 3 The implementation process of the intelligent scheduling method for irrigation area water use provided by an embodiment of the present invention is shown. The step of "obtaining the attributes of the crops planted in each slice" is described in detail as follows: S301: Based on the attributes, determine the priority of each slice, wherein the priorities include: high, medium and low, generate a label using the priority, and insert the label into the corresponding slice.

[0048] The priority of each slice is determined according to the crops planted in each slice, where the priorities are divided into high, medium and low, and a label generated by the priority is inserted into the slice.

[0049] S302: Embed an upshift strategy into the high-priority slice.

[0050] When a high-priority slice is defined as a target node, the upgrade strategy is initiated; the upgrade strategy is to directly push the target node into the level corresponding to the medium level.

[0051] For example, when the three slices A, B and C in a certain irrigation area are relatively dry, A and C are planted with wheat. Since wheat is highly drought-resistant, its priority is low, while B is planted with local specialty crops with unique economic value, so its priority is high. At this time, A and C conduct drought prevention and control by finding water supply fields and establishing waterway scheduling, while B directly draws water from the river to ensure the normal growth of specialty crops.

[0052] In Example 5, Figure 3 The implementation process of the intelligent water dispatching method for irrigation areas provided by the embodiment of the present invention is shown. The step of "finding nodes with water demand and defining them as target nodes" is described in detail as follows: S303: Pushing a selection window with integrated soil moisture level to the user, and determining soil moisture data based on the user's selection.

[0053] A selection window is pushed to the user, allowing the user to preliminarily determine the soil moisture level based on production experience, and the user's preliminary determination results are combined with the output results of the deep learning model to finally determine the soil moisture data.

[0054] S304: Integrate the soil moisture data and attributes through the corresponding relationship to determine whether the slice is lacking in water. If so, define the corresponding leaf node as the target node.

[0055] Based on the soil moisture data and the properties of the crops planted in the slice, determine whether the slice is short of water. If it is short of water, the leaf node is defined as the target node. In addition, the water shortage situation in the target node needs to be updated according to the preset frequency.

[0056] In Example 6, Figure 4 The implementation process of the intelligent water scheduling method for irrigation areas provided by an embodiment of the present invention is shown. The steps of "updating the target node based on a preset frequency, setting the push and pop steps of the target node in the hierarchy, triggering the start of the scheduling strategy, and scheduling the water volume of the irrigation area" are described in detail as follows: S401: linking an initial node at the entrance of the layer, and pushing the target node into the layer corresponding to the lightness through the initial node.

[0057] Locate the entrance of the hierarchy and insert the initial node at the entrance. The initial node is used to coordinate the push and pop of the target node to avoid confusion in pushing the hierarchy.

[0058] S402: Based on the soil moisture data and attributes, the target node is updated to determine whether the target node continues to be pushed in. If not, the target node is popped out.

[0059] When the target node is pushed into the level corresponding to the mild degree, the target node is updated to determine whether the soil in the target node is becoming increasingly dry; if so, the target node is continued to be pushed into the level corresponding to the moderate degree, if not, the target node is popped out.
