[0014] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0015] A method and device for rotation irrigation of farmland water and fertilizer according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0016] Figure 1 It is a flow chart of a method for rotation irrigation of farmland water and fertilizer provided in an embodiment of the present application. Figure 1 The farmland water-fertilizer rotation irrigation method can be executed by a computer or a server, or software on a computer or a server. Figure 1 As shown, the farmland water-fertilizer rotation irrigation method includes:

[0017] S101, obtaining first distribution data of a farmland, second distribution data of a pipeline in the farmland, and third distribution data of a solenoid valve;

[0018] S102, dividing the farmland into a plurality of grids according to the first distribution data, the second distribution data and the third distribution data;

[0019] S103, identifying the varieties and growth stages of crops in the farmland, and collecting meteorological data of the area where the farmland is located and soil data of each grid;

[0020] S104, determining the amount of water and fertilizer to be applied to each grid according to the variety, growth stage, meteorological data, and soil data and area of ​​each grid;

[0021] S105, dividing the plurality of grids into a plurality of rotation irrigation groups according to the position, water application amount and fertilizer application amount of each grid, wherein each rotation irrigation group includes one or more grids;

[0022] S106, based on the positions of the various rotation irrigation groups, using an optimal path algorithm to generate an optimal order for irrigating the various rotation irrigation groups;

[0023] S107, irrigating the grids in each rotation irrigation group in sequence according to the optimal order.

[0024] The first distribution data is data such as the location and area of ​​the farmland, and the second distribution data is data such as the location of the pipeline laid in the farmland, through which the farmland is irrigated. The third distribution data is data such as the location of the solenoid valve set in the farmland, and the solenoid valve serves as an irrigation switch. There are multiple pipelines and multiple solenoid valves in the farmland. According to the first distribution data, the second distribution data and the third distribution data, the farmland can be divided into multiple grids, and one pipeline and one solenoid valve are used to irrigate one or more grids. The pipelines and solenoid valves are evenly distributed among multiple grids as much as possible to improve the irrigation efficiency.

[0025] Meteorological data include wind speed, rainfall, temperature, air humidity, light intensity, etc. Soil data include humidity, temperature, pH value, EC value (Electrical Conductivity), etc. The amount of water and fertilizer applied to each grid is determined according to the variety, growth stage, meteorological data, soil data and area of ​​each grid. The relationship between the variety, growth stage, meteorological data and soil data of each grid and the unit water application (unit fertilizer application) can be obtained by statistically analyzing the historical irrigation data, and then the unit water application (unit fertilizer application) is multiplied by the area of ​​each grid to obtain the water application (fertilizer application). According to the position, water application and fertilizer application of each grid, multiple grids are divided into multiple rotation irrigation groups. Grids in similar positions can be divided together as a rotation irrigation group, and then multiple rotation irrigation groups are adjusted according to the principle that the water application and fertilizer application of each grid in the same rotation irrigation group are similar to obtain the final division result.

[0026] Each irrigation group is taken as a target, and based on the position of each irrigation group, the optimal path algorithm is used to generate the optimal order of irrigation for each irrigation group. This makes the loss of irrigation for each irrigation group the least, which is equivalent to the shortest path traversing each irrigation group. The optimal path algorithm is an existing algorithm and will not be described here. Finally, the grids in each irrigation group are irrigated in turn according to the optimal order.

[0027] In view of the shortcomings of the prior art, the present application proposes an automated water-fertilizer rotation irrigation system, which aims to solve the problems existing in the traditional system through innovations such as precise grid recognition, multi-mode irrigation configuration, intelligent pressure regulation, and abnormal monitoring and recovery. The specific goals include:

[0028] Grid-based precision irrigation: Based on farmland drawings, the area of ​​each grid in the field is accurately identified, and irrigation plans can be configured by quantity or time, and the irrigation quantity or time of each grid can be automatically calculated. Through the rotation irrigation template, the irrigation sequence can be scientifically arranged to ensure the efficiency and uniformity of farmland irrigation.

[0029] Intelligent pressure regulation: By real-time monitoring of the remote pressure of the irrigation system, the pipeline pressure is automatically adjusted to ensure consistent irrigation pressure in different areas of the field, solving the problem of irrigation differences caused by uneven pressure.

[0030] Multi-mode irrigation: Flexibly configure by grid area or irrigation time to provide adaptable solutions for different crops or farmland conditions and improve water and fertilizer utilization efficiency.

[0031] According to the technical solution provided in the embodiment of the present application, the first distribution data of the farmland, the second distribution data of the pipeline in the farmland and the third distribution data of the solenoid valve are obtained; the farmland is divided into multiple grids according to the first distribution data, the second distribution data and the third distribution data; the variety and growth stage of the crops in the farmland are identified, and the meteorological data of the area where the farmland is located and the soil data of each grid are collected; the amount of water and fertilizer applied to each grid is determined according to the variety, growth stage, meteorological data and the soil data and area of ​​each grid; according to the position, water application amount and fertilizer application amount of each grid, the multiple grids are divided into multiple rotation irrigation groups, wherein each rotation irrigation group contains one or more grids; based on the position of each rotation irrigation group, the optimal path algorithm is used to generate the optimal order of irrigating each rotation irrigation group; according to the optimal order, the grids in each rotation irrigation group are irrigated in sequence. The above technical means can solve the problem that farmland water and fertilizer cannot be accurately irrigated in the prior art, thereby improving the efficiency of water and fertilizer irrigation.

[0032] Furthermore, before collecting soil data of each grid, the method also includes: obtaining the coverage of the solenoid valve; and dividing the farmland into a plurality of grids according to the coverage, the first distribution data, the second distribution data and the third distribution data.

[0033] The farmland is divided into multiple grids, and one pipeline and one solenoid valve are used to irrigate one or more grids. The pipelines and solenoid valves are evenly distributed among multiple grids as much as possible, and each grid is within the coverage of the solenoid valve assigned to it, so as to improve the irrigation efficiency.

[0034] Furthermore, identifying the varieties and growth stages of crops in the farmland includes: obtaining images of the crops in the farmland; using a large language model to identify the varieties and growth stages of the crops from the images; wherein the large language model has been trained and can identify the varieties and growth stages of the crops from the images.

[0035] Before using the large language model to identify the varieties and growth stages of crops from images, the training images are input into the large language model to identify the varieties and growth stages of crops in the training images; the loss between the identified varieties and the labeled varieties is calculated, and the loss between the identified growth stages and the labeled growth stages is calculated, and the large language model is optimized based on the loss.

[0036] Furthermore, the amount of water and fertilizer applied for each grid is determined according to the variety, growth stage, meteorological data, soil data and area of ​​each grid, including: determining the unit amount of water and unit amount of fertilizer applied for each grid according to the variety, growth stage, meteorological data and soil data of each grid; calculating the amount of water and fertilizer applied for each grid based on the area, unit amount of water and unit amount of fertilizer applied for each grid.

[0037] The relationship between the variety, growth stage, meteorological data and soil data of each grid and the unit water application amount (unit fertilizer application amount) can be obtained by statistically analyzing the historical irrigation data. The unit water application amount (unit fertilizer application amount) can then be multiplied by the area of ​​each grid to obtain the water application amount (fertilizer application amount).

[0038] Figure 2 Schematic diagram of another method for rotating irrigation of farmland water and fertilizer provided in the embodiment of the present application. Figure 2 As shown, the method includes:

[0039] Execute the following loop:

[0040] S201, determining whether i is greater than N, wherein i is the serial number of the rotation irrigation group, the initial value of i is 1, and N is the number of the rotation irrigation groups;

[0041] S202, when i is greater than N, it is determined that all rotation irrigation groups have been irrigated and the cycle ends;

[0042] S203, when i is less than or equal to N, irrigate the grids in the i-th irrigation group and start timing. When the irrigation duration reaches the target duration, it is determined that the irrigation of the i-th irrigation group is completed, and i is updated with the value of i plus 1, wherein the target duration is calculated based on the water and fertilizer amounts of all grids in the i-th irrigation group and the irrigation flow rate of the solenoid valve.

[0043] The target duration is the sum of the water or fertilizer application amounts of all grids in the i-th irrigation group and the irrigation flow rate of the solenoid valve.

[0044] Furthermore, the grids in each rotation irrigation group are irrigated in turn according to the optimal order, including: for a rotation irrigation group, when the fertilizer application amount of all grids in the rotation irrigation group is zero but the water application amount is not zero, the irrigation pump is started and the water fertilizer machine is turned off: the irrigation amount corresponding to the rotation irrigation group is calculated based on the water application amount of all grids in the rotation irrigation group, the grids in the rotation irrigation group are irrigated and the flow meter is started, and when the value on the flow meter is equal to the irrigation amount corresponding to the rotation irrigation group, it is determined that the irrigation of the rotation irrigation group is completed; or the irrigation time corresponding to the rotation irrigation group is calculated based on the water application amount of all grids in the rotation irrigation group and the irrigation flow rate of the solenoid valve, the grids in the rotation irrigation group are irrigated and the timing is started, and when the irrigation time reaches the irrigation time, it is determined that the irrigation of the rotation irrigation group is completed.

[0045] The irrigation pump is responsible for controlling the water, and the water and fertilizer machine is responsible for pumping and injecting fertilizer. The fertilizer amount of all grids in the rotation irrigation group is zero but the water amount is not zero, which means that only water is needed at this time, and no fertilizer is needed. Therefore, start the irrigation pump and turn off the water and fertilizer machine. The sum of the water amount of all grids in the rotation irrigation group is used as the irrigation amount corresponding to the rotation irrigation group. The sum of the water amount of all grids in the rotation irrigation group divided by the irrigation flow rate is the irrigation duration.

[0046] Furthermore, the grids in each rotation irrigation group are irrigated in turn according to the optimal order, including: for a rotation irrigation group, when the fertilizer amount of all grids in the rotation irrigation group is not zero but the water amount is zero, the irrigation pump is started, and the water-fertilizer machine is started: the irrigation amount corresponding to the rotation irrigation group is calculated based on the fertilizer amount of all grids in the rotation irrigation group, the grids in the rotation irrigation group are irrigated and the flow meter is started, when the value on the flow meter is equal to the irrigation amount corresponding to the rotation irrigation group, the water-fertilizer machine is turned off, and the grids in the rotation irrigation group are continued to be irrigated for a preset time to determine that the rotation irrigation group is irrigated; or the irrigation time corresponding to the rotation irrigation group is calculated based on the water amount of all grids in the rotation irrigation group and the irrigation flow rate of the solenoid valve, the grids in the rotation irrigation group are irrigated and the timing is started, when the irrigation time reaches the irrigation time, the water-fertilizer machine is turned off, and the grids in the rotation irrigation group are continued to be irrigated for a preset time to determine that the irrigation of the rotation irrigation group is completed.

[0047] The amount of fertilizer applied to all grids in the irrigation group is not zero, but the amount of water applied is zero, indicating that fertilizer is needed at this time. Farmland fertilization is to inject fertilizer into water, so start the irrigation pump and the water fertilizer machine. When the value on the flow meter is equal to the irrigation amount corresponding to the irrigation group, it means that the fertilizer is enough, and the water fertilizer machine is turned off. Continue to irrigate the grids in the irrigation group for the preset time to clean the fertilizer residue in the pipeline.

[0048] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0064] Multi-mode irrigation: Flexibly configure by grid area or irrigation time to provide adaptable solutions for different crops or farmland conditions and improve water and fertilizer utilization efficiency.

[0065] According to the technical solution provided in the embodiment of the present application, the first distribution data of the farmland, the second distribution data of the pipeline in the farmland and the third distribution data of the solenoid valve are obtained; the farmland is divided into multiple grids according to the first distribution data, the second distribution data and the third distribution data; the variety and growth stage of the crops in the farmland are identified, and the meteorological data of the area where the farmland is located and the soil data of each grid are collected; the amount of water and fertilizer applied to each grid is determined according to the variety, growth stage, meteorological data and the soil data and area of ​​each grid; according to the position, water application amount and fertilizer application amount of each grid, the multiple grids are divided into multiple rotation irrigation groups, wherein each rotation irrigation group contains one or more grids; based on the position of each rotation irrigation group, the optimal path algorithm is used to generate the optimal order of irrigating each rotation irrigation group; according to the optimal order, the grids in each rotation irrigation group are irrigated in sequence. The above technical means can solve the problem that farmland water and fertilizer cannot be accurately irrigated in the prior art, thereby improving the efficiency of water and fertilizer irrigation.

[0066] In some embodiments, the first division module 302 is further configured to obtain the coverage of the solenoid valve; and divide the farmland into a plurality of grids according to the coverage, the first distribution data, the second distribution data, and the third distribution data.

[0067] The farmland is divided into multiple grids, and one pipeline and one solenoid valve are used to irrigate one or more grids. The pipelines and solenoid valves are evenly distributed among multiple grids as much as possible, and each grid is within the coverage of the solenoid valve assigned to it, so as to improve the irrigation efficiency.

[0068] In some embodiments, the recognition module 303 is further configured to acquire images of crops in a farmland; and use a large language model to recognize the variety and growth stage of the crops from the images; wherein the large language model has been trained and can recognize the variety and growth stage of the crops from the images.

[0069] Before using the large language model to identify the varieties and growth stages of crops from images, the training images are input into the large language model to identify the varieties and growth stages of crops in the training images; the loss between the identified varieties and the labeled varieties is calculated, and the loss between the identified growth stages and the labeled growth stages is calculated, and the large language model is optimized based on the loss.

[0070] In some embodiments, the determination module 304 is also configured to determine the unit water application amount and unit fertilizer application amount of each grid according to the variety, growth stage, meteorological data and soil data of each grid; and calculate the water application amount and fertilizer application amount of each grid based on the area, unit water application amount and unit fertilizer application amount of each grid.

[0071] The relationship between the variety, growth stage, meteorological data and soil data of each grid and the unit water application amount (unit fertilizer application amount) can be obtained by statistically analyzing the historical irrigation data.

[0072] In some embodiments, the irrigation module 307 is also configured to execute the following loop: determine whether i is greater than N, where i is the serial number of the rotation irrigation group, the initial value of i is 1, and N is the number of the rotation irrigation groups; when i is greater than N, determine that all the rotation irrigation groups have been irrigated and end the loop; when i is less than or equal to N, irrigate the grids in the i-th rotation irrigation group and start timing, and when the irrigation time reaches the target time, determine that the i-th rotation irrigation group has been irrigated, and update i with the value of i plus 1, where the target time is calculated based on the water and fertilizer application amounts of all grids in the i-th rotation irrigation group and the irrigation flow rate of the solenoid valve.

[0073] The target duration is the sum of the water or fertilizer application amounts of all grids in the i-th irrigation group and the irrigation flow rate of the solenoid valve.

[0074] In some embodiments, the irrigation module 307 is also configured to, for a rotation irrigation group, when the fertilizer application amount of all grids in the rotation irrigation group is zero but the water application amount is not zero, start the irrigation pump and turn off the water-fertilizer machine: calculate the irrigation amount corresponding to the rotation irrigation group based on the water application amount of all grids in the rotation irrigation group, irrigate the grids in the rotation irrigation group and start the flow meter, and when the value on the flow meter is equal to the irrigation amount corresponding to the rotation irrigation group, determine that the irrigation of the rotation irrigation group is completed; or calculate the irrigation time corresponding to the rotation irrigation group based on the water application amount of all grids in the rotation irrigation group and the irrigation flow rate of the solenoid valve, irrigate the grids in the rotation irrigation group and start timing, and when the irrigation time reaches the irrigation time, determine that the irrigation of the rotation irrigation group is completed.

[0075] The irrigation pump is responsible for controlling the water, and the water and fertilizer machine is responsible for pumping and injecting fertilizer. The fertilizer amount of all grids in the rotation irrigation group is zero but the water amount is not zero, which means that only water is needed at this time, and no fertilizer is needed. Therefore, start the irrigation pump and turn off the water and fertilizer machine. The sum of the water amount of all grids in the rotation irrigation group is used as the irrigation amount corresponding to the rotation irrigation group. The sum of the water amount of all grids in the rotation irrigation group divided by the irrigation flow rate is the irrigation duration.

[0077] The amount of fertilizer applied to all grids in the irrigation group is not zero, but the amount of water applied is zero, indicating that fertilizer is needed at this time. Farmland fertilization is to inject fertilizer into water, so start the irrigation pump and the water fertilizer machine. When the value on the flow meter is equal to the irrigation amount corresponding to the irrigation group, it means that the fertilizer is enough, and the water fertilizer machine is turned off. Continue to irrigate the grids in the irrigation group for the preset time to clean the fertilizer residue in the pipeline.
