[0002] The division of irrigation rotation groups is not only an important part of water conservancy irrigation planning and design, but also a difficult problem that must be faced in production practice. By dividing the irrigation area into different rotation groups, planned irrigation can be carried out according to the water demand of different areas, achieving a reasonable allocation of water resources, protecting the irrigation system and improving irrigation efficiency.

[0003] At present, factors such as flow balance and pressure balance are generally considered during the design stage of the irrigation network, and the network is optimized. However, due to changes in factors such as project construction and production water management, in production practice, with changes in plant and crop varieties, network transformation, area shrinkage, or even cancellation of plots, the actual irrigation area situation may be significantly different from the design plan, and most irrigation projects cannot fully implement the irrigation plan according to the planned rotation irrigation group.

[0004] In order to meet the timely and appropriate water requirements of plants and crops, users or irrigation managers need to divide irrigation groups according to actual production needs. However, the division of irrigation groups requires users to not only understand the soil, plant and crop requirements of each irrigation area, but also understand and even master professional knowledge such as pipe network hydraulics and fluid mechanics. If users divide irrigation groups based on personal experience, it is difficult to guarantee the optimal division results, and it is time-consuming and labor-intensive. Summary of the invention

This embodiment can be applied to the situation where the irrigation area is reasonably divided into multiple rotation groups in combination with the multi-dimensional information of the irrigation area. The method can be executed by an automatic division device for irrigation rotation groups. The automatic division device for irrigation rotation groups can be implemented in the form of hardware and / or software, and can generally be configured in a computer or irrigation cloud platform with data processing capabilities. Figure 1 As shown, the method includes:

[0033] S110, obtaining an initial system pipe network diagram, irrigation district information, and pump room header information of the pump room system, and annotating the initial system pipe network diagram according to the irrigation district information to obtain a target system pipe network diagram.

[0034] Optionally, the irrigation cloud platform has the capabilities of irrigation information collection, processing, irrigation decision-making and information exchange, and can maintain the initial system pipe network diagram of the pump room system, irrigation area information and pump room header information in real time. In the irrigation cloud platform, the system pipe network diagram is stored in the form of an electronic map. When the irrigation cloud platform receives the initial system pipe network diagram hand-drawn by the user, the hand-drawn initial system pipe network diagram can be converted to generate an electronic map that can be recognized by the irrigation cloud platform.

[0035] Optionally, a pump room system may include multiple irrigation areas, and the multiple irrigation areas may be divided into the same irrigation group. During the irrigation process, the pump room starts to fill water into the pipes at all levels under the pump room, and then the irrigation pipes transport the water resources to each irrigation area. Each irrigation area can be connected to the trunk and branch pipes through a field valve. When the field valve is opened, the water resources in the trunk and branch pipes can flow to the irrigation area corresponding to the valve. Conversely, when the field valve is closed, the water resources in the trunk and branch pipes cannot flow to the irrigation area corresponding to the valve.

[0036] Optionally, the initial system pipe network diagram may include the total scope of the project area, the location of the pipe network, the pipeline network, the pipeline attribute information, the pipe point information, the pipe point status, and other auxiliary information such as the pipeline elevation line.

[0038] Optionally, the irrigation area information may include location information, crop information, soil information, irrigation information, terrain information, and field header and status information.

[0039] Optionally, the location information may include information such as the area range, field valve position, altitude and relative height of each irrigation area. Based on the area range and field valve position in the location information, the regional location of each irrigation area and the field valve position can be marked in the initial system pipe network diagram.

[0040] Optionally, the water flow direction of each level of pipeline is determined based on the pump room head outlet position, pipeline network position, pipeline direction, regional position of each irrigation area, and field valve position in the initial system pipeline network diagram, and the pipeline network water flow direction is marked in the initial system pipeline network diagram.

[0041] Optionally, after marking the water flow direction, the subordinate relationship between the pipelines at each level and the irrigation areas can be determined according to the positional relationship between the pipelines and the positional relationship between the irrigation areas and the pipelines. According to the subordinate relationship between the pipelines at each level and the irrigation areas and the distance between the irrigation areas and the pipelines and the pump room, the pipelines at each level and the irrigation areas can be numbered to obtain the target system pipe network diagram.

[0042] Figure 2 is a schematic diagram of an optional system pipe network diagram. Figure 2 As shown in the figure, the pump house system includes main pipelines and trunk and branch pipelines. Both the main pipelines and trunk and branch pipelines can transport water to the irrigation area through field valves. Figure 2 The circle between the middle pipe and the irrigation area can represent the field valve. The pipes at each level can be numbered according to the subordinate relationship between the main pipe and the trunk and branch pipes. The number of the irrigation area can be determined according to the number of the pipe that transports water to it. This is only an example and does not limit the specific form of expression in the system pipe network diagram and the pump room system structure.

[0043] S120. Determine the planned irrigation volume for each irrigation area in the target system pipe network diagram according to the irrigation area information.

[0044] Optionally, the actual crop evapotranspiration of each irrigation plot is calculated separately based on the crop information, soil information in the irrigation plot information and weather information during the target irrigation time period.

[0045] Optionally, crops may refer to green plants, crops, etc., but are not limited to the above crop types.

[0046] Optionally, the target time period may refer to the time period between the most recent rainfall and the current date, or may refer to the time period between the most recent irrigation and the current date.

[0047] Optionally, after determining the actual evapotranspiration of the crops in the irrigation area, the planned irrigation amount of the irrigation area may be determined based on the water balance principle.

[0048] Optionally, the planned irrigation amount may also be a value set by the user.

[0049] S130, generating the initial rotation irrigation group division result according to the target system pipe network diagram, irrigation area information, pump room header information and the planned irrigation volume of each irrigation area.

[0050] Optionally, the irrigation information in the irrigation area information may include the irrigation method, the sprinkler used and its pressure and flow parameters, and the layout of the sprinkler; the irrigation method may include sprinkler irrigation, micro sprinkler irrigation, drip irrigation, and pipe irrigation.

[0051] Optionally, the terrain information in the irrigation cell information may include elevation and relative height difference.

[0052] Optionally, based on the planned irrigation amount of each irrigation area and crop information, the first round of irrigation group division results are obtained, and the first round of irrigation group division results can ensure that the irrigation amount of each irrigation area meets the crop growth demand.

[0053] Optionally, based on the irrigation information of each irrigation area, the second round of irrigation group division results are obtained. The second round of irrigation group division results can ensure that the flow and pressure of each irrigation area can meet the requirements of the irrigation method. Different irrigation methods require different irrigation flows and irrigation pressures, and different emitters can support different irrigation flows and irrigation pressures.

[0054] Optionally, based on the results of the first and second rounds of irrigation group division, a division result that can meet both crop growth needs and irrigation method needs can be obtained. However, considering that the terrain information of the irrigation area is also one of the important factors affecting the irrigation pressure, if the irrigation area is at a higher altitude than the pump house, the pressure provided by the pump house may not be able to meet the pressure requirements of the emitter. Therefore, the third round of irrigation group division results can be obtained based on the terrain information combined with the results of the first and second rounds of irrigation group division.

[0055] Optionally, after obtaining the results of the third round of irrigation group division, determine whether the irrigation areas in each irrigation group are adjacent or similar irrigation areas based on the pipelines at each level and the irrigation area numbers at each level in the target system pipe network diagram, determine whether the pressure and water output provided by the pump room meet the irrigation needs of each irrigation group based on the pump room header information, and determine whether the soil conditions of each irrigation area can support the planned irrigation volume based on the soil information of the irrigation area, and based on the judgment results of the above conditions, correct the results of the third round of irrigation group division to obtain the initial irrigation group division results.

[0056] Optionally, the initial rotation irrigation group division result is obtained based on the irrigation areas with the same irrigation method and similar irrigation pressure, while ensuring flow balance, pressure balance, the same crops and water management mode, and taking into account multiple factors such as pipeline diameter, pipeline flow direction, field valve pressure requirements, etc.

[0058] Optionally, the plurality of irrigation indicators may refer to a flow balance indicator, a pressure balance indicator, and a flow demand and a pressure demand.

[0059] Optionally, based on the initial rotation irrigation group division results, it can be determined whether each irrigation area in each rotation irrigation group meets the basic conditions of flow balance and pressure balance, and reversely infer whether the flow and pressure of each irrigation area meet the requirements of the planned irrigation volume and irrigation method. If the above irrigation indicators are all met, the initial rotation irrigation group division result is determined as the target rotation irrigation group division result. Otherwise, the initial rotation irrigation group division result needs to be adjusted again until the irrigation indicators are met.

[0060] The technical solution of the embodiment of the present invention obtains the initial system pipe network diagram, irrigation area information and pump room header information of the pump room system, annotates the initial system pipe network diagram to obtain the target system pipe network diagram, determines the planned irrigation volume of each irrigation area in the target system pipe network diagram, and generates the initial rotation irrigation group division result according to the target system pipe network diagram, irrigation area information, pump room header information and the planned irrigation volume of each irrigation area, and then detects multiple irrigation indicators in the initial rotation irrigation group division result. The target rotation irrigation group division result is obtained according to the detection result. On the basis of the built pump room system, considering the real-time irrigation situation, crop situation, irrigation demand and other factors under the pump room system, the rotation irrigation group division result can be automatically generated scientifically and reasonably, and the flow and pressure of each divided rotation irrigation group can be balanced, thereby improving the efficiency of rotation irrigation group division and effectively saving human resources. In addition, the method is also applicable to the planning and design stage of irrigation projects. After determining the basic information such as pipeline direction, pump room, irrigation area, etc., the method can also be used to divide irrigation rotation irrigation groups in the design stage, and lay the foundation for the hydraulic calculation of the main pipeline size.
