[0030] With the advancement of agricultural modernization and the widespread application of water-saving irrigation technology, the importance of irrigation has become increasingly prominent.

[0031] The irrigation head is one of the core components of the irrigation system. It is the bridge between the water source and the irrigation system. It is responsible for introducing the water source into the irrigation system and performing preliminary treatment (such as filtration, pressurization, etc.) to ensure the cleanliness of the irrigation water and improve irrigation efficiency.

[0032] A well house is a house or structure built around a wellhead. In an irrigation system, a well house is mainly used to protect the wellhead and related equipment, such as pumps, pipes, valves, etc., to prevent them from being eroded and damaged by the natural environment. At the same time, the well house also provides the necessary space and conditions for the operation and maintenance of the equipment. In addition, the well house can also be integrated with an intelligent control system to achieve remote monitoring and automated management of the irrigation process. In a system that uses groundwater for irrigation, a well is one of the main ways to obtain water. At this time, the well house is located above or near the well to provide protection for the well and its ancillary equipment.

[0033] Irrigation system refers to an engineering system that transports water to farmland or plots through a series of facilities to meet the water needs of plant growth. The irrigation system mainly includes water sources, water transmission and distribution facilities and ancillary buildings. The basic principles include water supply, transportation and distribution, control and monitoring. By rationally utilizing water resources and scientifically controlling irrigation volume and irrigation time, the irrigation system can provide plants with the right amount of water and nutrients to promote the growth and development of crops.

[0034] At present, the irrigation head can be understood as a fixed pump house designed according to the well house or irrigation river and channel. It is the core system of water supply and fertilization of the irrigation system. It is connected between the well house and the irrigation system through the well pipe of the well house and the water pipe of the irrigation system. The jurisdiction of the irrigation head is limited, usually within 500 mu of land, and no more than 1,000 mu at most. This is because the groundwater or water supply system is insufficient, and it is difficult to meet the irrigation needs of large fields; if the area of ​​the land under the jurisdiction of the irrigation head is too large, the water pump of the irrigation head will be required to be high, the water pump power will be large and the pipe diameter will be thick, and the cost of investing in the head will be high and the maintenance cost will be high; if the area is too large, the field pipe network will be too complicated, and the pressure loss will be greater the farther away from the pump house, and it will be difficult to ensure the balance of pressure and flow in each irrigation area; therefore, an irrigation head is often used to irrigate 200 mu of land, which is a more common design, especially in some areas where water sources are not scarce.

[0035] However, such a distribution design of irrigation heads introduces the following problem: in a large-scale plot, there are usually multiple well houses (including water wells), and each well house needs to be equipped with an irrigation head, which will significantly increase the overall construction cost of the irrigation system. In view of this, the embodiment of the present application proposes an irrigation method and system, which realizes the mobile function of the irrigation head by equipping the irrigation head with a mobile component, and can travel between multiple well houses, so that multiple well houses can share one irrigation head, thereby effectively improving the utilization rate of the irrigation head and reducing the overall cost of the irrigation system.

[0036] Figure 1 It is a schematic diagram of an irrigation head operation mechanism applicable to an embodiment of the present application.

[0037] refer to Figure 1 As shown, the irrigation head is a movable irrigation head, for example, it can be moved according to a preset moving route, or can be moved in a corresponding manner according to control information from a user or a backend server.

[0038] exist Figure 1 In the diagram, the plot is divided into four sub-plots, in each of the four sub-plots, a well house is set up, and each well house is used to protect a water well. In other words, each sub-plot is set up with a well as the water source of the irrigation system, and each well is provided with a well pipe for the irrigation head to pump water out of the well through the well pipe.

[0039] In addition, water pipelines of the irrigation system are arranged in the four sub-areas, and the irrigation head is used to transport the water pumped out of the well to the corresponding position of the sub-area plot to be irrigated by the water pipeline through the water pipeline. When the entire irrigation system is in a non-irrigation state, the well pipeline and the water pipeline may be in a non-connected state. When the irrigation head reaches the designated well house, it can be connected to the well pipeline and the water pipeline respectively, so that the well pipeline and the water pipeline are in a connected state. Then, based on the water pump of the irrigation head, the water in the well is pumped out and transported to the water pipeline of the irrigation system to realize the corresponding irrigation plan. During the execution of the irrigation plan, the entire irrigation system is in an irrigation state.

[0040] From this, it can be seen that after the irrigation head completes the irrigation of the sub-area plot corresponding to the first well house, it can move to the second well house based on a preset route or according to the control information of the user or the background server, and complete the irrigation plan for the sub-area plot corresponding to the second well house, and so on.

[0041] The detailed process of the above irrigation head operation mechanism is described below.

[0042] Figure 2 It is a schematic flow chart of an irrigation method 200 proposed in an embodiment of the present application.

[0043] The method 200 may be performed by a movable irrigation head, that is, the irrigation head is equipped with a movable component, and the method 200 comprises the following steps:

[0044] S210: Determine first movement information, where the first movement information is used to indicate that the irrigation head moves to a position of a first well house.

[0045] In some possible embodiments, the first motion information may be sent by a user through a software application on a terminal device based on a wireless communication network, and received and determined by an irrigation head to trigger an operation of moving the irrigation head to the location of a first well house, wherein the terminal device may belong to a master control center to which the irrigation system belongs.

[0046] In some possible embodiments, the first movement information may be pre-stored locally in the irrigation head, and the irrigation head may read and determine the first movement information after every preset period of time to trigger the operation of moving the irrigation head to the position of the first well house.

[0047] In some possible embodiments, the first motion information may be configured by a background server, and the background server may send the first motion information after a preset period of time, and the first motion information is received and determined by the irrigation head to trigger the operation of the irrigation head moving to the position of the first well house. Among them, the background server may pre-store the location information of multiple well houses under the jurisdiction of the irrigation head, and formulate a corresponding motion plan for the irrigation head according to the location information of the multiple well houses, and the motion plan includes the above-mentioned first motion information. In addition, the background server can also obtain information such as valve control equipment and rotation irrigation groups of at least part of the irrigation system corresponding to each well house, so that the background server can directly determine the rotation irrigation plot information, and then determine the valve control equipment information, and further determine the corresponding irrigation plan, and associate the irrigation plan with the corresponding irrigation head, and send it to the irrigation head at an appropriate time (for example, the irrigation head moves to the corresponding well house position), which is described in detail in subsequent embodiments.

[0048] S220: When the irrigation head reaches the position of the first well house, determine the first irrigation plan, the first irrigation plan is used to indicate the way in which the first irrigation system irrigates the first plot of land, the first well house corresponds to the first plot of land, and the first plot of land is provided with a water pipeline of the first irrigation system.

[0049] In some possible embodiments, the moving parts of the irrigation head may mainly include a power system, a transmission system, a travel system, a steering system and a braking system. Among them, the power system is used to provide the power required for the movement of the irrigation head, including a motor and a battery pack; the transmission system is used to transmit the power generated by the engine to the wheels so that the irrigation head can move, and the transmission system may include a clutch, a transmission, a universal transmission device, a main reducer, a differential and a half shaft, etc.; the travel system is used to support and install the parts of the irrigation head, transmit and bear various loads on and under the irrigation head to ensure the normal travel of the irrigation head; the steering system is used to ensure that the irrigation head can travel in the specified direction, and the steering system may include a steering control mechanism, a steering gear and a steering transmission mechanism; the braking system is used to slow down and ensure reliable parking, and the braking system may include a brake disc, a brake pad, a master cylinder and a slave cylinder, etc.

[0050] In some possible embodiments, the above-mentioned irrigation head may also include an obstacle avoidance system, which includes: a sensor for detecting the surrounding environment and the existence of obstacles, and the sensor may include an ultrasonic sensor, an infrared sensor, a lidar, a camera, etc.; a controller for processing the data collected by the sensor and making decisions according to preset logic and algorithms. The controller may be an embedded system, a microcontroller, etc. The controller may be equipped with corresponding algorithms, for example, data processing and decision-making based on the data collected by the sensor, and the algorithm may include obstacle detection, path planning, speed control, etc.

[0051] In some possible embodiments, the first irrigation plan may be sent by the background server and received and determined by the irrigation header. For example, when the irrigation header reaches the location of the first well house, the target location information is sent to the background server, and the target location information is used by the background server to determine the location of the irrigation header reaching the first well house and trigger the sending of the first irrigation plan to the irrigation header; accordingly, the background server sends the first irrigation plan to the irrigation header in response to the irrigation header reaching the location of the first well house; then the irrigation header receives the first irrigation plan from the background server to determine the first irrigation plan.

[0052] In some possible embodiments, the first irrigation plan may be pre-stored in the background server, and after the background server determines that the irrigation head has arrived at the first well house, the first irrigation plan may be directly sent to the irrigation head. Alternatively, after the background server determines that the irrigation head has arrived at the first well house, the background server may actively obtain relevant information about the first plot of land corresponding to the first well house, such as the scope of the first plot of land, soil quality, local weather, valve group used to irrigate the first plot of land, and other information, and the background server may be equipped with a trained first neural network model, and the relevant information about the first plot of land may be used as the input of the first neural network model, and after data iteration and solution of the first neural network model, the first irrigation plan may be outputted and then sent to the irrigation head.

[0053] In some possible embodiments, the first neural network model may also be replaced by a first machine learning model constructed based on the professional knowledge and experience of business personnel, and the first machine learning model belongs to an expert model.

[0054] In some possible embodiments, the first irrigation plan can also be determined by the irrigation head based on the analysis of the relevant information sent by the background server. For example, when the irrigation head reaches the position of the first well house, the target position information will be sent to the background server, and the target position information is used by the background server to determine the position of the irrigation head at the first well house, and trigger the sending of the information of the first plot and the information of the first valve group to the irrigation head, wherein the information of the first plot is used to indicate the soil quality of the first plot, and the information of the first valve group is used to indicate the sub-division of the first plot corresponding to each valve; the background server responds to the position of the irrigation head reaching the first well house, and sends the information of the first plot and the information of the first valve group of the first irrigation system to the irrigation head. The irrigation head can analyze the relevant information sent by the background server through the first neural network model or the first machine learning model to determine the first irrigation plan.

[0055] In some possible embodiments, the irrigation head is equipped with a built-in processor, which can calculate the water flow required for each sub-division of the first plot of land based on the soil quality of the first plot of land. Combined with multiple valves corresponding to each sub-division, the control quantity of each valve can be determined. The control quantity is used to control the water flow output by the corresponding valve, the water delivery duration, the valve switching sequence, etc. This information can be used as the content of the first irrigation plan to determine the first irrigation plan.

[0056] In some possible embodiments, in the process of determining the first irrigation plan, the background server or the irrigation head may also combine the local real-time weather information of the first plot, the weather information including temperature, rainfall period, rainfall, etc. For example, if the current temperature of the first plot is greater than a preset temperature threshold, the water flow rate for irrigation may be adaptively increased; if there is rainfall in the area where the first plot is located during the first period, the water volume used for irrigation during the first period may be adaptively reduced.

[0057] In some possible embodiments, the irrigation head may have a mobile gateway function and a location acquisition function, so that the real-time location of the irrigation head can be automatically tracked, so the irrigation head can report its own location information to the background server. For example, in the process of the irrigation head moving to the location of the first well house, multiple real-time location information of the irrigation head can be periodically sent to the background server, and the multiple real-time location information includes target location information (for example, at least one real-time location information sent after arriving at the first well house), wherein the irrigation head can dynamically adjust the period of sending real-time location information to the background server, and the adjustment basis can include information such as the moving speed and road conditions of the irrigation head; for example, the faster the moving speed, the shorter the period; the more complex the road conditions, the longer the period, etc.

[0058] Alternatively, in the process of moving toward the position of the first well house, the position of the irrigation head itself is obtained in real time, and when the distance between the self-position and the position of the first well house (the position of the first well house can be preset locally in the irrigation head, or the irrigation head can be obtained from the background server side) is less than or equal to the first distance threshold, the target position information is determined, and the target position information includes the current position of the irrigation head itself, and then the target position information is sent to the background server. Among them, the above-mentioned target position information can also include information such as the current time and the identifier of the irrigation head. The background server can determine the irrigation plan for the irrigation head according to the current time and the identifier of the irrigation head. It can be seen that different irrigation heads can be used to execute different irrigation plans, thereby realizing differentiated management of multiple irrigation heads.

[0059] In some possible embodiments, the backend server may determine the position where the irrigation head reaches the first well house in the following manner:

[0060] Method 1: The backend server receives real-time location information from the irrigation head, and when N real-time location information received continuously are used to indicate the same location, it is determined that the irrigation head has arrived at the location of the first well house.

[0061] Method 2: The background server first determines the location of the first well house, and the background server receives real-time location information from the irrigation head. When the location indicated by the received real-time location information from the irrigation head is less than or equal to a first distance threshold from the location of the first well house, the background server determines that the irrigation head has arrived at the first well house.

[0062] It should be understood that when the irrigation header periodically sends real-time location information to the background server, the background server can also periodically receive the real-time location information from the irrigation header in sequence. Of course, the background server can also obtain multiple real-time location information sent in sequence by the irrigation header at one time after a period of time.

[0063] Mode 3: When the background server receives the target position information from the irrigation head, the background server determines the position where the irrigation head reaches the first well house, and the target position information is used to indicate the position where the irrigation head reaches the first well house.

[0064] Among them, in mode 3, the irrigation header will not periodically send its own real-time location information to the background server, so the background server will not periodically receive the real-time location information from the irrigation header.

[0065] S230: When it is detected that the irrigation head is respectively connected to the well pipe of the first well house and the water supply pipe of the first irrigation system, water extracted from the first well house is transported to the first irrigation system through the water supply pipe, and first control information is sent to the first irrigation system according to the first irrigation plan. The first control information is used to adjust the opening period and opening degree of each valve of the first valve group in the first irrigation system to complete the first irrigation plan.

[0066] There may be multiple opening periods to achieve periodic opening, and the opening degree corresponding to each period may also be different.

[0067] In some possible embodiments, the irrigation head includes a first pipe opening and a second pipe opening, wherein the first pipe opening is used to be fixedly connected to a water well pipe, and the second pipe opening is used to be fixedly connected to a water delivery pipe. Therefore, the above detection that the irrigation head is connected to the water well pipe of the first well house and the water delivery pipe of the first irrigation system respectively may refer to the detection that the first pipe opening is fixedly connected to the water well pipe, and the detection that the second pipe opening is connected to the water delivery pipe.

[0068] In addition, considering that the pressure at the first pipe opening will increase after the first pipe opening is fixed to the water well pipe, and the same is true for the second pipe opening, pressure sensors can be respectively set at the first pipe opening and the second pipe opening. When the pressure value detected by the pressure sensor is greater than or equal to the preset pressure value, it can be determined that the irrigation head has been fixedly connected to the water well pipe or the water supply pipe.

[0069] In some possible embodiments, the above-mentioned irrigation head can integrate the functions of mobile gateway, irrigation water pump start and stop, and irrigation main line frequency control, among which the irrigation main line frequency control uses frequency conversion technology to control the operation of the main water pump in the irrigation system to achieve precise irrigation, ensure the accuracy of the execution of the above-mentioned first irrigation plan, and achieve energy saving and consumption reduction.

[0070] In some possible embodiments, the first control information may be part of the content of the first irrigation plan. The first control information may be a valve control device information, which refers to the status and performance parameters of valves, pumps, sensors and other devices used to control water flow distribution and irrigation process in the irrigation system. Through the valve control device, the irrigation water volume and irrigation time of each plot can be accurately controlled to ensure the uniformity and efficiency of irrigation.

[0071] In some possible embodiments, the valve control device information may be determined based on the rotational irrigation plot information (may be determined by the above-mentioned backend server or the processor of the irrigation head), and the rotational irrigation plot information refers to the basic conditions and irrigation requirements of the farmland plots included in the rotational irrigation system management, including the geographical location, area, soil type, crop type, growth cycle, water demand, etc. of the plots. When the valve control device information is determined by the processor of the irrigation head, the above-mentioned rotational irrigation plot information may be sent to the irrigation head by the backend server as part of the information content of the above-mentioned first plot.

[0072] Based on the above technical solution, by introducing a movable irrigation head into the irrigation system, the irrigation head can be moved to multiple well houses in sequence, and each time it arrives at a well house, it will cooperate with the well house and the irrigation system corresponding to the well house to complete the corresponding irrigation plan, so that multiple well houses can share one irrigation head, which can effectively improve the utilization rate of the irrigation head and reduce the overall cost of the irrigation system.
