A wheel irrigation group control method and device, a storage medium and a terminal device

Abstract

The application provides a wheel irrigation group control method and device, a storage medium and a terminal device. When a current wheel irrigation group completes a current irrigation task, a target group is controlled to perform a wheel irrigation switching task. The wheel irrigation switching task is a task of opening a set number of water outlets in the target group. The target group is a wheel irrigation group that does not perform the current irrigation task in an irrigation system. In the case that the wheel irrigation switching task is successful, the water outlets in the current wheel irrigation group are controlled to be closed. The success of the wheel irrigation switching task indicates that the proportion of the opened water outlets in the target group is greater than or equal to a first preset proportion within a first preset time length. Even if the water outlets in the current wheel irrigation group are closed, the water pressure in the water delivery pipe will not suddenly increase, thereby avoiding damage to the water delivery pipe and playing a role in protecting the irrigation system.

Description

Technical Field

[0001] This application relates to the field of irrigation, and more specifically, to a method, apparatus, storage medium, and terminal equipment for controlling rotating irrigation groups. Background Technology

[0002] Smart agriculture can significantly save manpower, improve agricultural efficiency, and ensure the quality of agricultural operations, thereby improving harvest results. Therefore, smart agriculture is currently a very popular topic and has attracted the attention of technicians in various fields. An important component of smart agriculture is intelligent irrigation. For example, an irrigation system is set up in farmland. This system includes water outlets and water delivery pipes. The water delivery pipes are connected to the outlets on the water outlets. Water or fertilizer solution enters the water delivery pipes through the outlets, thus transporting it to the planting site of the crops for irrigation or fertilization.

[0003] However, in large-scale planting, the number of water outlets and sluices in the planting area is enormous. Opening all the outlets simultaneously would affect the irrigation effect or efficiency. Therefore, how to efficiently manage the irrigation system has become a difficult problem for those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide a method, apparatus, storage medium, and terminal equipment for controlling rotating irrigation groups, so as to at least partially improve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

[0006] In a first aspect, embodiments of this application provide a method for controlling rotational irrigation groups, the method comprising:

[0007] When the current irrigation group completes its current irrigation task, the target group is controlled to perform the irrigation switching task.

[0008] The irrigation switching task is to open a set number of outlets in the target group, where the target group is the irrigation group in the irrigation system that has not performed the current irrigation task.

[0009] If the irrigation switching task is successful, the outlet of the current irrigation group will be closed.

[0010] The successful completion of the irrigation switching task is characterized by the proportion of open outlets in the target group being greater than or equal to the first preset proportion within a first preset time period.

[0011] Secondly, embodiments of this application provide a rotating irrigation group control device, the device comprising:

[0012] The switching unit is used to control the target group to perform the rotation switching task when the current rotation irrigation group completes the current irrigation task;

[0013] The irrigation switching task is to open a set number of outlets in the target group, where the target group is the irrigation group in the irrigation system that has not performed the current irrigation task.

[0014] The control unit is used to close the outlet of the current irrigation group when the irrigation switching task is successful.

[0015] The successful completion of the irrigation switching task is characterized by the proportion of open outlets in the target group being greater than or equal to the first preset proportion within a first preset time period.

[0016] Thirdly, embodiments of this application provide a storage medium storing a computer program thereon, which, when executed by a processor, implements the above-described method.

[0017] Fourthly, embodiments of this application provide a terminal device, the terminal device comprising: a processor and a memory, the memory being used to store one or more programs; when the one or more programs are executed by the processor, the above-described method is implemented.

[0018] Compared to existing technologies, the irrigation group control method, apparatus, storage medium, and terminal equipment provided in this application control a target group to perform an irrigation switching task when the current irrigation group completes its current irrigation cycle. The irrigation switching task involves opening a predetermined number of outlets within the target group, which is the irrigation group in the irrigation system that has not yet performed its current irrigation cycle. If the irrigation switching task is successful, the outlets in the current irrigation group are closed. Successful irrigation switching is characterized by the percentage of open outlets in the target group being greater than or equal to a first preset percentage within a first preset time period. Even closing the outlets in the current irrigation group does not cause a sudden increase in water pressure in the water supply pipe, thus preventing damage to the water supply pipe and protecting the irrigation system.

[0033] In the description of this application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Taking the irrigation and fertilization of an area (e.g., a cotton field) using an irrigation system as an example, the irrigation system includes water outlets, water delivery pipes, and drip irrigation tape. It should be understood that the water outlets can be evenly distributed throughout the cotton field, or installed by workers as needed. Optionally, the water outlets are equipped with electric valves (e.g., electric three-way valves). Each electric valve has at least one outlet; of course, the number of outlets on an electric valve can be one, two, or more. Each outlet is connected to a corresponding drip irrigation tape via a different water delivery pipe. Water or fertilizer solution can also reach the roots of the cotton plants through the "outlet-water delivery pipe-drip irrigation tape" system.

[0036] When the area to be irrigated is too large, for example, 140 mu (approximately 9.3 hectares), and there are many water outlets in the area, such as 14 outlets, opening all the outlets at the same time as the water pump means that 140 mu of land needs to be irrigated simultaneously. This may result in insufficient water pressure after the pump, leading to insufficient pressure at the outlets of the drip irrigation tape in the field, and water cannot drip out through the outlets of the drip irrigation tape.

[0037] In one possible implementation, all the water outlets within the irrigation area can be grouped into at least two irrigation rotation groups. Continuing with the previous example, assuming each water outlet has two outlets, for instance, 14 water outlets can be divided into two irrigation rotation groups. Each rotation group corresponds to an irrigation area of ​​70 mu (approximately 4.7 hectares), and each rotation group contains 14 outlets. After the water pump is started, only one outlet in one rotation group needs to be opened, ensuring sufficient water pressure at the drip irrigation tape's outlet holes, allowing water to drip smoothly and thus implementing accurate and efficient irrigation.

[0038] The irrigation system includes at least two rotating irrigation groups, such as Irrigation Group A and Irrigation Group B. In one possible implementation, switching between Irrigation Group A and Irrigation Group B can be achieved based on the irrigation duration of each group. For example, Irrigation Group A starts irrigating at 12:00. It is calculated that Irrigation Group A needs 5 hours to complete irrigation. At 17:00, all outlets associated with Irrigation Group B will automatically open, and then automatically close all outlets associated with Irrigation Group A after 10 minutes. The process for obtaining the 5-hour irrigation duration for Irrigation Group A is as follows: the irrigated area for Irrigation Group A is 75 mu (approximately 4.3 hectares), and the standard water consumption for this irrigation is 20 cubic meters per second. 3 / mu, the total irrigation volume of Irrigation Group A this time is 1500m³. 3 The water pump used for irrigation group A has a flow rate of approximately 300 m³ / h. 3 / h, so it can be calculated that it takes 5 hours for irrigation group A to complete irrigation.

[0039] In the above scheme, 10 minutes after opening all the outlets associated with irrigation group B, all outlets in irrigation group A must be closed, regardless of the number of outlets already opened in irrigation group B. For example, if irrigation group B currently has 4 open outlets, but its associated outlet count is 14, this indicates that the number of open outlets in irrigation group B is too low. At this point, the water or fertilizer solution after the pump needs to flow through the currently open outlets in irrigation group B to the corresponding drip irrigation belt, leading to excessive water pressure in irrigation group B and a risk of the water pipeline rupturing due to excessive pressure. For instance, at 5:00 PM, irrigation group A completes irrigation and automatically opens all the outlets associated with irrigation group B (approximately 14 outlets). However, the electric valves in irrigation group B malfunction, opening only 4 outlets instead of the required 14. At this point, 10 minutes have passed since the outlets associated with irrigation group B were first opened. By default, all outlets associated with the A-stage irrigation group are closed. As a result, with the water pump running normally, only four outlets are open, leading to excessive water pressure in the pipeline that exceeds its pressure-bearing capacity, causing the pipeline to rupture.

[0040] Furthermore, in the above scheme, the actual water consumption of the rotating irrigation group may deviate significantly from the planned water consumption, failing to achieve the goal of accurately controlling the water consumption per acre for the rotating irrigation group. During pump operation, the pump flow rate fluctuates due to factors such as the area of ​​the rotating irrigation group, voltage, and current. The pump flow rate used to calculate the irrigation duration of rotating irrigation group A is 300 m³ / s. 3 / h, but the actual flow rate might be 330m. 3 / h, so if 1500m² is to be irrigated 3 The actual irrigation time was only 4.5 hours, but it took 5 hours, resulting in an extra 0.5 hours of water being poured, approximately 155m³. 3 This translates to approximately 2m² per mu. 3 / mu, which deviates significantly from the planned usage.

[0041] To overcome the above problems, this application provides a terminal device, which may be a computer device, a server device, or a management module in an irrigation system. Please refer to... Figure 1 A schematic diagram of the terminal device. The terminal device includes a processor 10, a memory 11, and a bus 12. The processor 10 and the memory 11 are connected via the bus 12. The processor 10 is used to execute executable modules, such as computer programs, stored in the memory 11.

[0042] Processor 10 can be an integrated circuit chip with signal processing capabilities. During implementation, each step of the rotating irrigation group control method can be completed through integrated logic circuits in the hardware or software instructions within processor 10. The aforementioned processor 10 can be a general-purpose processor, including a Central Processing Unit (CPU), a Network Processor (NP), etc.; it can also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components.

[0043] The memory 11 may include high-speed random access memory (RAM) and may also include non-volatile memory, such as at least one disk storage device.

[0044] Bus 12 can be an ISA (Industry Standard Architecture) bus, a PCI (Peripheral Component Interconnect) bus, or an EISA (Extended Industry Standard Architecture) bus, etc. Figure 1 The symbol is represented by a single double-headed arrow, but this does not mean that there is only one bus 12 or one type of bus 12.

[0045] The memory 11 is used to store programs, such as the program corresponding to the irrigation group control device. The irrigation group control device includes at least one software function module that can be stored in the memory 11 in the form of software or firmware or embedded in the operating system (OS) of the terminal device. After receiving the execution instruction, the processor 10 executes the program to implement the irrigation group control method.

[0046] The terminal device provided in this application embodiment may also include a communication interface 13. The communication interface 13 is connected to the processor 10 via a bus.

[0047] It should be understood that when the outlet valve in the irrigation system is equipped with an electric valve, the terminal device can communicate wirelessly or wiredly with the electric valve through the communication interface 13 to complete the exchange of command information.

[0048] It should be understood that, Figure 1 The structure shown is only a partial schematic diagram of the terminal device; the terminal device may also include components that are larger than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof.

[0049] The rotating irrigation group control method provided in this application embodiment can be applied to, but is not limited to, any method for... Figure 1 For the specific procedures of the terminal devices shown, please refer to [link / reference]. Figure 2 The control methods for rotational irrigation groups include S103, S104, S105, and S106, which are described in detail below.

[0050] S103, determine one of the irrigation groups that has never performed the irrigation switching task as the new target group.

[0051] The target group is the irrigation group in the irrigation system that has not performed the current irrigation task and the rotation irrigation switching task.

[0052] Taking an irrigation system comprising irrigation groups A, B, C, and D as an example, assuming irrigation group A is the first group to perform the irrigation task, when irrigation group A performs its irrigation task or completes its current cycle, one of the three groups (B, C, and D) can be selected as the new target group. For example, choosing irrigation group B as the new target group means that after irrigation group A completes its irrigation task, irrigation group B will be controlled to perform the irrigation task.

[0053] It should be understood that before executing the irrigation task, the B-type irrigation group needs to perform the irrigation switching task in S104, which involves opening a set number of outlets within the B-type irrigation group. This set number can refer to the total number of outlets in the irrigation group, or it can be set based on actual water pressure requirements or experience. If the B-type irrigation group fails to execute the irrigation switching task, it cannot be used as the target group and a new target group needs to be determined. Otherwise, uneven irrigation will occur, and excessive water pressure may damage the water supply pipes after the A-type irrigation group closes its outlets. Optionally, the C-type irrigation group can be used as the new target group. If the C-type irrigation group successfully executes the irrigation switching task, it becomes the new current irrigation group. When the C-type irrigation group executes the irrigation task or completes its current irrigation cycle, a new target group needs to be determined. Since the B-type irrigation group failed to execute the irrigation switching task previously, it cannot be used as the new target group; only the D-type irrigation group can be used as the new target irrigation group.

[0054] S104: When the current irrigation group completes its current irrigation task, control the target group to perform the irrigation switching task.

[0055] Among them, the rotation irrigation switching task is to open a set number of water outlets in the target group, and the target group is the rotation irrigation group in the irrigation system that has not performed the current round of irrigation task.

[0056] It should be understood that an irrigation system includes at least two rotation irrigation groups. Taking an irrigation system comprising rotation irrigation groups A, B, C, and D as an example, assuming rotation irrigation group A is the current rotation irrigation group, it is currently performing an irrigation task, meaning the outlets in rotation irrigation group A are open, irrigating or fertilizing the crops. When rotation irrigation group A completes its current irrigation task, it needs to select one of the rotation irrigation groups (B, C, and D) that did not perform the current irrigation task as the target group; let's assume rotation irrigation group B is chosen as the target group. At this point, it is necessary to control rotation irrigation group B to perform a rotation switching task, that is, to control a set number of outlets within rotation irrigation group B to open.

[0057] It should be noted that when the target group is performing the rotational irrigation switching task, the outlet of the current rotational irrigation group (rotational irrigation group A) remains open to avoid excessive water pressure.

[0058] S105, determine whether the rotational irrigation switching task was successful. If yes, proceed to S106; otherwise, repeat S103.

[0059] Among them, the successful switching of irrigation tasks is characterized by the proportion of open outlets in the target group being greater than or equal to the first preset proportion within the first preset time length.

[0060] Optionally, the first preset time length can be 10 minutes, and the first preset percentage can be 80%. Continuing with the example of irrigation group A as the current irrigation group and irrigation group B as the target irrigation group, assuming the total number of outlets in irrigation group B is 20, if the number of outlets opened in irrigation group B within ten minutes is greater than or equal to 16, it indicates that the percentage of opened outlets in irrigation group B is greater than or equal to the first preset percentage. At this time, executing S106 ensures that even if the outlets in irrigation group A are closed, there will be no sudden increase in water pressure in the water supply pipe, thus preventing damage to the water supply pipe and protecting the irrigation system.

[0061] It should be understood that if the B-round irrigation group successfully performs the rotation switching task, the B-round irrigation group can be used as the new current rotation irrigation group.

[0062] Continuing with the previous example, if irrigation group B fails to perform the irrigation switching task, then irrigation group B cannot be used as the target group and a new target group needs to be determined. Otherwise, uneven irrigation will occur, and excessive water pressure will occur after the outlet of irrigation group A is closed, potentially damaging the water delivery pipe. Therefore, a new target group needs to be determined, i.e., S103 needs to be executed.

[0063] S106, if the irrigation switching task is successful, control the outlet of the current irrigation group to close.

[0064] It should be understood that the current irrigation group has completed its irrigation task. If the outlet of the current irrigation group is not closed, it will lead to over-irrigation in the irrigation area corresponding to the current irrigation group, which will not only waste resources but also affect crop growth. Therefore, it is necessary to control the closure of the outlet of the current irrigation group.

[0065] In summary, this application provides a method for controlling a rotating irrigation group. When the current rotating irrigation group completes its current irrigation cycle, it controls a target group to perform a rotating irrigation switching task. The rotating irrigation switching task involves opening a predetermined number of outlets within the target group, which is the rotating irrigation group in the irrigation system that has not yet performed its current irrigation cycle. If the rotating irrigation switching task is successful, the outlets in the current rotating irrigation group are controlled to close. A successful rotating irrigation switching task is characterized by the percentage of open outlets in the target group being greater than or equal to a first preset percentage within a first preset time period. Even if the outlets in the current rotating irrigation group are closed, there will be no sudden increase in water pressure in the water supply pipe, thus avoiding damage to the water supply pipe and protecting the irrigation system.

[0066] It should be noted that even if the irrigation switching task is deemed successful, it is still necessary to open the remaining outlets in the target group that have not yet been opened in order to avoid affecting the irrigation effect.

[0067] exist Figure 2 Based on this, when the outlet is installed on the electric valve inside the outlet pile, regarding the content in S104, this application embodiment also provides a possible implementation method, please refer to... Figure 3 S104 includes: S104-1, which is described in detail below.

[0068] S104-1, send an opening command to all electric valves in the target group so that the electric valves open the corresponding outlets after receiving the opening command.

[0069] Optionally, an electric valve is a valve controlled by an electric actuator to open and close the valve. It can be divided into two parts: the upper part is the electric actuator, and the lower part is the valve. The electric actuator can be a motor or other electric structure.

[0070] By sending open commands to all electric valves in the target group, the irrigation switching task can be completed quickly and efficiently without manual intervention, saving time and effort.

[0071] Please continue to refer to this. Figure 3 Regarding how to determine whether the irrigation switching task is successful, this application embodiment also provides a possible implementation method, such as... Figure 3As shown, S105 includes: S105-1, S105-2, S105-3, S105-4, S105-5 and S105-6, which are described in detail below.

[0072] S105-1 receives the successful opening information from the electric valve.

[0073] The successful opening message includes an indicator that the water outlet has been successfully opened.

[0074] It should be understood that after opening the corresponding outlet, the electric valve can send a successful opening message to the terminal device. This message includes the identifier of the successfully opened outlet, which can be the outlet's number within the irrigation system. It should also be understood that when an electric valve has two or more outlets, such as outlet 50A and outlet 50B on electric valve number 50, both outlets 50A and 50B belong to the target group. When electric valve number 50 receives the opening command for outlets 50A and 50B, if outlet 50A opens successfully but outlet 50B fails to open, electric valve number 50 will only send a successful opening message for outlet 50A.

[0075] It should be noted that if the communication link between the electric valve and the terminal device is broken, the electric valve will not receive the opening command, will not open the corresponding outlet, and will not provide feedback on successful opening. If the electric valve can receive the opening command, but fails to open the corresponding outlet due to mechanical failure (such as jamming), it will also not provide feedback on successful opening.

[0076] S105-2, count the marks of the successfully opened water outlets and determine the number of opened outlets.

[0077] Optionally, the number of successfully opened outlet markers can be counted, which is the number of opened outlets.

[0078] S105-3, the percentage value is determined based on the number of outlets that have been opened and the total number of outlets in the target group.

[0079] For example, if 8 outlets have been opened and the total number of outlets in the target group is 10, then the percentage is 80%.

[0080] Optionally, the terminal device can retrieve the total number of outlets corresponding to each contour group.

[0081] S105-4, Determine whether the percentage of open outlets in the target group is less than the first preset percentage. If yes, proceed to S105-5; otherwise, proceed to S105-6.

[0082] It should be understood that if the percentage of open outlets in the target group is less than the first preset percentage, it means that the number of successfully opened outlets is too small. In this case, S105-5 is executed to determine that the rotation irrigation switching task has failed; otherwise, S105-6 is executed to determine that the rotation irrigation switching task has succeeded.

[0083] S105-5, the irrigation switching task has failed.

[0084] After S105-5, S103 can be repeated to determine a new target group.

[0085] S105-6, the irrigation rotation switchover task has been successfully completed.

[0086] After S105-6, S106 can be executed to control the closure of the outlet in the current irrigation group.

[0087] exist Figure 2 Based on the above, regarding the content in S104 and S105, this application embodiment also provides a possible implementation method, please refer to the following.

[0088] In one possible implementation, the terminal device can also generate an activation prompt and send it to the user terminal. This prompt reminds the user to open all outlets within the target group. After opening a specific outlet (e.g., the outlet corresponding to electric valve number 72), the operator can send a success message via the user terminal. This success message may include an identifier for the outlet corresponding to electric valve number 72. For example, by inputting a command to switch the status of the outlet corresponding to electric valve number 72 from closed to open on the user's screen, the user terminal generates a success message and sends it to the terminal device when the status of the outlet corresponding to electric valve number 72 changes from closed to open. The terminal device can determine whether the irrigation switching task was successful based on the number of received success messages.

[0089] exist Figure 2 Based on this, for the content in S106, this application embodiment also provides a possible implementation method, please refer to... Figure 4 S106 includes: S106-1, S106-2 and S106-3, which are described in detail below.

[0090] S106-1, sequentially close each outlet in the current irrigation group.

[0091] It should be understood that rapidly closing all the outlets in the current irrigation group simultaneously within a short period could cause a significant increase in water pressure, posing a risk of damaging the water supply pipes due to excessive pressure. Therefore, it is necessary to close each outlet in the current irrigation group sequentially, one by one.

[0092] Optionally, a shut-off command can be sent to the electric valve, causing it to close the corresponding outlet upon receiving the command. A shut-off operation prompt can also be sent to the user terminal, reminding the user to close all outlets within the target group.

[0093] S106-2, whenever an outlet is closed, obtain the current pressure of the outlet in the open state.

[0094] It should be understood that, in order to further improve the protection effect, when each outlet in the current irrigation group is closed, the current pressure of the outlet in the open state is obtained, so as to monitor the current pressure of the outlet and avoid excessive water pressure.

[0095] Optionally, a water pressure sensor is installed inside the water outlet. The water pressure sensor is used to obtain the current pressure of the water outlet and transmit the current pressure of the water outlet to the terminal device.

[0096] S106-3, when the current pressure at any outlet exceeds the preset pressure threshold, pause and close the remaining outlets in the current irrigation group.

[0097] Optionally, users can set the pressure threshold via software. Since different farms use different drip irrigation tape materials, the pressure-bearing capacity of the tape also varies. Therefore, the pressure at the outlet of the water outlet will differ, and users need to conduct a water flow test to determine the pressure threshold before setting it.

[0098] It should be understood that if the current pressure at any outlet exceeds the preset pressure threshold, it indicates a potential safety hazard. If the outlet is closed, the water pressure may continue to increase, which could increase the possibility of damage to the water pipe. Therefore, it is necessary to close the remaining outlets in the current irrigation group.

[0099] Continue to close the remaining open outlets in the current irrigation group until the current pressure of all the set number of outlets is less than or equal to the preset pressure threshold.

[0100] Please continue to refer to this. Figure 4 Regarding how to further improve the safety of the irrigation system during the switching of irrigation groups, this application also provides a possible implementation method, such as... Figure 4 As shown, when the current pressure at any outlet is greater than the preset pressure threshold, the rotation irrigation group control method also includes: S107, which is described in detail below.

[0101] S107 transmits a pressure over-limit warning to the user terminal to remind the user to check and maintain the irrigation system.

[0102] Optionally, the pressure overshoot alert can be sent via SMS or telephone voice message. After the user performs inspection and maintenance, the current pressure at the outlet of the irrigation system returns to below the pressure threshold, ensuring the safety of the irrigation system.

[0103] exist Figure 2 Based on this, regarding how to determine whether the current irrigation group has completed its irrigation task, this application embodiment also provides a possible implementation method, please refer to... Figure 5 Prior to S104, the rotation irrigation group control methods also included S101 and S102, which are described in detail below.

[0104] S101, obtain the irrigation amount of the current irrigation group.

[0105] Optionally, the irrigation volume of the current irrigation group can be obtained based on a water meter installed at the inlet of the irrigation system; that is, the irrigation volume from the time when the current irrigation group performs the irrigation switching task to the current time. For example, if the water meter reading at the time when the current irrigation group performs the irrigation switching task is 'a', the water meter reading at the current time is 'b', and the irrigation volume of the current irrigation group is w = 'ba', with the water meter unit being meters (m). 3 .

[0106] S102, when the irrigation volume of the current irrigation group is greater than the preset irrigation threshold, determine that the current irrigation group has completed the irrigation task for this round.

[0107] Optionally, the irrigation threshold can be obtained from the irrigated area of ​​the current irrigation group and the preset water consumption per mu (unit of land area). For example, G = t·s, where s represents the irrigated area and t represents the preset water consumption per mu.

[0108] It should be understood that if the current irrigation volume of the irrigation group is greater than the preset irrigation threshold, it means that the irrigation area of ​​the current irrigation group has been fully irrigated. If irrigation continues, over-irrigation will occur. Therefore, it is determined that the current irrigation group has completed the irrigation task for this round.

[0109] In this embodiment, the current irrigation group determines whether it has completed its irrigation task by directly measuring the current irrigation volume. This overcomes the bias problem in related technologies that determine whether the irrigation task has been completed by measuring the irrigation duration, ensuring precise irrigation and avoiding resource waste.

[0110] Please continue to refer to this. Figure 5 S103 can be executed after S102, which will not be elaborated here.

[0111] Continuing with the example above, the irrigation system includes irrigation groups A, B, C, and D. In one possible implementation, if irrigation group B fails to perform its irrigation cycle switching task, after irrigation groups A, C, and D have all completed their current irrigation cycle, the terminal device can send a prompt to the user terminal to activate irrigation group B. This allows the user to manually switch the state of irrigation group B's outlet, thereby completing the irrigation task for the entire area to be irrigated.

[0112] Please see Figure 6 , Figure 6 The irrigation group control device provided in this application embodiment can optionally be applied to the terminal equipment described above.

[0113] The rotation irrigation group control device includes: a switching unit 201 and a control unit 202.

[0114] The switching unit 201 is used to control the target group to perform the rotation switching task when the current rotation irrigation group completes the current irrigation task;

[0115] Among them, the rotation irrigation switching task is to open a set number of water outlets in the target group, and the target group is the rotation irrigation group in the irrigation system that has not performed the current round of irrigation task.

[0116] The control unit 202 is used to close the outlet of the current irrigation group when the irrigation switching task is successful.

[0117] Among them, the successful switching of irrigation tasks is characterized by the proportion of open outlets in the target group being greater than or equal to the first preset proportion within the first preset time length.

[0118] Optionally, the switching unit 201 can execute S104 as described above, and the control unit 202 can execute S101-S103 and S105-S107 as described above.
