[0105] S705. According to the dynamic irrigation plan, the operating status of the centrifugal pump, the high-pressure centrifugal pump, the solenoid valve group and the fertilizer injector is controlled through the control cabinet to achieve precise irrigation and fertilization.

[0106] Meteorological data is one of the important bases for generating irrigation plans, mainly including parameters such as rainfall, temperature, humidity and wind speed. These data are collected in real time by meteorological stations and transmitted to the irrigation management platform. Its working principle is to predict evaporation and crop water demand in the future by analyzing the rainfall, temperature, humidity and wind speed in meteorological data. Evaporation refers to the amount of water evaporated from the soil and plant surface into the atmosphere, and crop water demand refers to the amount of water required by crops during their growth. In actual implementation, the process of predicting evaporation and crop water demand is as follows: First, the irrigation management platform receives real-time meteorological data from the meteorological station. For example, assuming that the current rainfall is 10 mm, the temperature is 25 degrees Celsius, the humidity is 60%, and the wind speed is 3 meters per second; then, the platform calculates the evaporation and crop water demand in the next 24 hours based on these data and the preset meteorological model; for example, assuming that the predicted evaporation in the next 24 hours is 5 mm and the crop water demand is 8 mm, the platform will generate the corresponding irrigation plan based on these data. By predicting evaporation and crop water requirements, the irrigation system can adjust the amount of irrigation water in advance, avoiding insufficient or excessive irrigation caused by weather changes, and significantly improving irrigation efficiency and crop yields.

[0107] Soil moisture data and nutrient content data are another important basis for generating irrigation plans, mainly including parameters such as soil moisture, soil temperature, nitrogen content, phosphorus content and potassium content. These data are collected in real time by soil sensors and transmitted to the irrigation management platform. Its working principle is to determine the current soil moisture state and nutrient state by analyzing the soil moisture and soil temperature in the soil moisture data and the nitrogen, phosphorus and potassium content in the nutrient content data. The soil moisture state refers to whether the moisture content in the soil meets the crop needs, and the soil nutrient state refers to whether the nutrient content in the soil meets the crop needs. In actual implementation, the process of determining soil moisture and nutrient status is as follows: First, the irrigation management platform receives real-time data from soil sensors. For example, assuming that the current soil moisture is 20%, the soil temperature is 20 degrees Celsius, the nitrogen content is 50 mg / kg, the phosphorus content is 30 mg / kg, and the potassium content is 40 mg / kg; then, the platform calculates the current soil moisture and nutrient status based on these data and the preset soil model; for example, assuming that the soil moisture is lower than the preset threshold, the platform will determine that the current soil moisture is insufficient and the irrigation water volume needs to be increased; if the nitrogen content is lower than the preset threshold, the platform will determine that the current soil nitrogen nutrient is insufficient and the nitrogen fertilizer dosage needs to be increased. By determining the soil moisture and nutrient status, the irrigation system can accurately adjust the irrigation water and fertilizer application amount, avoiding the problem of poor crop growth caused by insufficient soil moisture and nutrients, and significantly improving irrigation efficiency and crop yield.

[0108] Irrigation water consumption and fertilizer consumption are important reference data for generating irrigation plans. They are mainly monitored in real time by flow meters and fertilizer injectors and transmitted to the irrigation management platform. Its working principle is to calculate the water demand and fertilizer demand of the current irrigation area by analyzing the irrigation water consumption and fertilizer consumption, combined with the preset crop growth model. Water demand refers to the amount of water required by crops in the current growth stage, and fertilizer demand refers to the amount of nutrients required by crops in the current growth stage. In actual implementation, the process of calculating water demand and fertilizer demand is as follows: First, the irrigation management platform receives real-time data from flow meters and fertilizer injectors. For example, assuming that the current irrigation water consumption is 10 cubic meters and the fertilizer consumption is 5 kilograms; then, the platform calculates the water demand and fertilizer demand of the current irrigation area based on these data and the preset crop growth model; for example, assuming that the crop growth model shows that the water demand in the current growth stage is 12 cubic meters and the fertilizer demand is 6 kilograms, the platform will generate the corresponding irrigation plan based on these data. By calculating the water and fertilizer requirements, the irrigation system can accurately adjust the amount of irrigation water and fertilizer, avoiding poor crop growth caused by insufficient or excessive irrigation water and fertilizer, and significantly improving irrigation efficiency and crop yields.

[0109] The dynamic irrigation plan is the core output of the irrigation system, which mainly includes parameters such as irrigation time, irrigation water volume, fertilizer type and fertilizer amount. Its working principle is to generate a dynamic irrigation plan based on evaporation, crop water demand, soil moisture status, soil nutrient status, water demand and fertilizer demand. In actual implementation, the process of generating a dynamic irrigation plan is as follows: First, the irrigation management platform calculates the irrigation time and amount of irrigation water in the current irrigation area based on the predicted evaporation, crop water requirement, soil moisture status, soil nutrient status, water requirement and fertilizer requirement; for example, assuming that the predicted evaporation in the next 24 hours is 5 mm, the crop water requirement is 8 mm, the soil moisture status is insufficient, and the water requirement is 12 cubic meters, the platform will generate a corresponding irrigation plan, including the irrigation time of 6 am and the irrigation water volume of 12 cubic meters; then, the platform calculates the type and amount of fertilizer to be applied in the current irrigation area based on the soil nutrient status and fertilizer requirement; for example, assuming that the soil nitrogen nutrient status is insufficient and the fertilizer requirement is 6 kg, the platform will generate a corresponding fertilization plan, including the type of fertilizer is nitrogen fertilizer and the amount of fertilizer is 6 kg. By generating a dynamic irrigation plan, the irrigation system can accurately adjust the irrigation and fertilization strategies according to real-time data, avoiding the problem of poor crop growth caused by inaccurate irrigation and fertilization, and significantly improving irrigation efficiency and crop yield.

[0110] The execution of the dynamic irrigation plan is achieved by controlling the operating status of the centrifugal pump, high-pressure centrifugal pump, solenoid valve group and fertilizer injector through the control cabinet. Its working principle is to adjust the operating parameters of each device according to the irrigation time, irrigation water volume, fertilizer type and fertilizer amount in the dynamic irrigation plan. In actual implementation, the process of controlling the operating status of the equipment is as follows: First, the control cabinet receives the dynamic irrigation plan from the irrigation management platform. For example, assuming that the dynamic irrigation plan requires irrigation to start at 6 o'clock in the morning, the irrigation water volume is 12 cubic meters, the fertilizer type is nitrogen fertilizer, and the fertilizer amount is 6 kilograms; then, the control cabinet adjusts the operating frequency of the centrifugal pump and the high-pressure centrifugal pump according to the dynamic irrigation plan to ensure that the water flow reaches 12 cubic meters / hour; at the same time, the control cabinet adjusts the opening and closing state of the solenoid valve group to ensure that the water flow is distributed to different irrigation areas; in addition, the control cabinet adjusts the operating status of the fertilizer injector to ensure that the amount of nitrogen fertilizer reaches 6 kilograms. By controlling the operating status of the equipment, the irrigation system can accurately execute the dynamic irrigation plan, avoiding uneven irrigation and poor crop growth caused by inaccurate equipment operation, and significantly improving irrigation efficiency and crop yield.

[0111] This implementation method generates a dynamic irrigation plan based on meteorological data, soil moisture data, nutrient content data, irrigation water consumption and fertilizer dosage, and accurately controls the operation status of the equipment, so that the irrigation system realizes efficient, accurate and intelligent irrigation and fertilization management. The analysis of meteorological data ensures that the irrigation system can adjust the irrigation water volume in advance according to meteorological changes, avoiding the problem of insufficient or excessive irrigation caused by meteorological changes; the analysis of soil moisture data and nutrient content data ensures that the irrigation system can accurately adjust the irrigation water volume and fertilizer dosage according to the soil state, avoiding the problem of poor crop growth caused by insufficient soil moisture and nutrients; the analysis of irrigation water consumption and fertilizer dosage ensures that the irrigation system can accurately adjust the irrigation water volume and fertilizer dosage according to crop needs, avoiding the problem of poor crop growth caused by insufficient or excessive irrigation water and fertilizer dosage; the generation and execution of dynamic irrigation plans ensure that the irrigation system can accurately adjust the irrigation and fertilization strategies according to real-time data, avoiding the problem of poor crop growth caused by inaccurate irrigation and fertilization. Overall, this technical solution significantly improves irrigation efficiency and crop yields, reduces the waste of water resources and fertilizers, and provides strong technical support for the sustainable development of modern agriculture.

[0112] In one implementation of this embodiment, a dynamic irrigation plan is generated based on evaporation, crop water requirement, moisture status, nutrient status, water requirement and fertilizer requirement, including the following steps:

[0113] S801. Calculate the net irrigation water requirement of the current irrigation area based on evaporation and crop water requirement, and determine whether supplementary irrigation is needed based on the current soil moisture status;

[0114] S802, according to the current soil nutrient status and fertilizer requirement, combined with the preset crop nutrient requirement model, determine the supplementary amount of different nutrients and generate a fertilization formula;

[0115] S803, based on the net irrigation water demand and the fertilization formula, and in combination with the terrain data and crop distribution data of the current irrigation area, generate a zoning irrigation plan, the zoning irrigation plan including the irrigation priority, irrigation water volume and fertilization volume of different irrigation areas;

[0116] S804. Dynamically adjust the irrigation time and irrigation water volume in the zoned irrigation plan according to the change of meteorological data to avoid repeated irrigation or water waste before and after rainfall, wherein the dynamically adjusted zoned irrigation plan is used to characterize the dynamic irrigation plan.

[0117] Net irrigation water requirement refers to the amount of water required by crops at the current growth stage minus natural rainfall and the amount of water already in the soil. Its working principle is to calculate the net irrigation water requirement of the current irrigation area by analyzing evaporation and crop water requirement, combined with the current soil moisture status, and determine whether supplementary irrigation is needed. Evaporation refers to the amount of water that evaporates from the soil and plant surface into the atmosphere, crop water requirement refers to the amount of water required by crops during their growth, and soil moisture status refers to whether the moisture content in the soil meets the needs of crops. In actual implementation, the process of calculating the net irrigation water requirement and determining whether supplementary irrigation is needed is as follows: First, the irrigation management platform receives real-time meteorological data from the weather station. For example, assuming that the current evaporation is 5 mm and the crop water requirement is 8 mm; then, the platform calculates the net irrigation water requirement based on these data and the current soil moisture status; for example, assuming that the current soil moisture status is insufficient and the soil moisture is 20%, the net irrigation water requirement is 8 mm-5 mm+2 mm (to supplement the insufficient soil moisture) = 5 mm; then, the platform determines whether supplementary irrigation is needed based on the net irrigation water requirement; for example, assuming that the net irrigation water requirement is 5 mm, the platform will generate a corresponding irrigation plan, including an irrigation water volume of 5 mm. By calculating the net irrigation water requirement and determining whether supplementary irrigation is needed, the irrigation system can accurately adjust the irrigation water volume, avoiding the problem of poor crop growth caused by insufficient or excessive irrigation, and significantly improving irrigation efficiency and crop yield.

[0118] Fertilization formula refers to the combination of fertilizer types and dosages generated according to crop needs. Its working principle is to analyze the current soil nutrient status and fertilizer requirements, combine with the preset crop nutrient requirement model, determine the amount of different nutrients to be supplemented, and generate a fertilization formula. Soil nutrient status refers to whether the nitrogen, phosphorus, and potassium content in the soil meets the needs of crops, and fertilizer requirements refer to the amount of nutrients required by crops at the current growth stage. In actual implementation, the process of determining the supplementary amount of different nutrients and generating a fertilization formula is as follows: First, the irrigation management platform receives real-time data from soil sensors. For example, assuming that the current soil nitrogen content is 50 mg / kg, the phosphorus content is 30 mg / kg, and the potassium content is 40 mg / kg; then, the platform calculates the supplementary amount of different nutrients based on these data and the preset crop nutrient demand model; for example, assuming that the crop nutrient demand model shows that the nitrogen requirement in the current growth stage is 60 mg / kg, the phosphorus requirement is 40 mg / kg, and the potassium requirement is 50 mg / kg, then the platform will generate a corresponding fertilization formula, including a nitrogen fertilizer supplement of 10 mg / kg, a phosphorus fertilizer supplement of 10 mg / kg, and a potassium fertilizer supplement of 10 mg / kg. By determining the supplementary amount of different nutrients and generating a fertilization formula, the irrigation system can accurately adjust the amount of fertilizer, avoid the problem of poor crop growth caused by insufficient or excessive fertilization, and significantly improve fertilizer utilization and crop yield.

[0119] The zoning irrigation plan refers to the combination of irrigation priority, irrigation water volume and fertilizer amount generated according to the terrain data and crop distribution data of different irrigation areas. Its working principle is to generate a zoning irrigation plan based on the net irrigation water requirement and fertilizer formula, combined with the terrain data and crop distribution data of the current irrigation area. The terrain data refers to the terrain height, slope and other information of the irrigation area, and the crop distribution data refers to the distribution of different crops in the irrigation area. In actual implementation, the process of generating a zoned irrigation plan is as follows: First, the irrigation management platform receives real-time data from terrain sensors and crop distribution sensors. For example, assuming that the terrain height difference in the current irrigation area is 2 meters, the slope is 5%, and the crop distribution is 60% wheat and 40% corn; then, the platform generates a zoned irrigation plan based on these data, combined with the net irrigation water requirement and fertilization formula; for example, assuming that the net irrigation water requirement is 5 mm, and the fertilization formula is 10 mg / kg nitrogen fertilizer, 10 mg / kg phosphate fertilizer, and 10 mg / kg potassium fertilizer, the platform will generate a corresponding zoned irrigation plan, including irrigation priority for wheat area, 5 mm irrigation water, and fertilization of 10 mg / kg nitrogen fertilizer, 10 mg / kg phosphate fertilizer, and 10 mg / kg potassium fertilizer. By generating a zoned irrigation plan, the irrigation system can accurately adjust the irrigation water and fertilization amount according to the needs of different irrigation areas, avoiding the problem of poor crop growth caused by uneven irrigation, and significantly improving irrigation efficiency and crop yield.

[0120] Dynamic adjustment of the zoning irrigation plan refers to dynamically adjusting the irrigation time and irrigation water volume in the zoning irrigation plan according to the changes in meteorological data to avoid repeated irrigation or water waste before and after rainfall. Its working principle is to dynamically adjust the irrigation time and irrigation water volume in the zoning irrigation plan by analyzing the rainfall, temperature, humidity and wind speed in the meteorological data. In actual implementation, the process of dynamically adjusting the zoning irrigation plan is as follows: First, the irrigation management platform receives real-time meteorological data from the meteorological station. For example, assuming that the current rainfall is 10 mm, the temperature is 25 degrees Celsius, the humidity is 60%, and the wind speed is 3 meters per second; then, the platform dynamically adjusts the irrigation time and irrigation water volume in the zoning irrigation plan based on these data; for example, assuming that the original irrigation time of the zoning irrigation plan is 6 o'clock in the morning and the irrigation water volume is 5 mm, the platform will adjust the irrigation time to 2 o'clock in the afternoon and the irrigation water volume to 3 mm according to the current rainfall. By dynamically adjusting the zoning irrigation plan, the irrigation system can accurately adjust the irrigation time and irrigation water volume according to meteorological changes, avoiding the problem of poor crop growth caused by repeated irrigation or water waste before and after rainfall, and significantly improving irrigation efficiency and crop yield.

[0121] This embodiment generates a dynamic irrigation plan based on evaporation, crop water demand, water status, nutrient status, water demand and fertilizer demand, and dynamically adjusts the zoning irrigation plan, so that the irrigation system achieves efficient, accurate and intelligent irrigation and fertilization management. Calculating the net irrigation water demand and determining whether supplementary irrigation is needed ensures that the irrigation system can accurately adjust the irrigation water volume according to crop demand and soil status, avoiding the problem of poor crop growth due to insufficient or excessive irrigation; determining the supplementary amount of different nutrients and generating a fertilization formula ensures that the irrigation system can accurately adjust the amount of fertilizer according to crop demand and soil status, avoiding the problem of poor crop growth due to insufficient or excessive fertilization; generating a zoning irrigation plan ensures that the irrigation system can accurately adjust the amount of irrigation water and fertilizer according to the needs of different irrigation areas, avoiding the problem of poor crop growth due to uneven irrigation; dynamically adjusting the zoning irrigation plan ensures that the irrigation system can accurately adjust the irrigation time and amount of irrigation water according to meteorological changes, avoiding the problem of poor crop growth due to repeated irrigation or water waste before and after rainfall.

[0126] Meteorological data is one of the important bases for generating irrigation plans, mainly including parameters such as rainfall, temperature, humidity and wind speed. The implementation principle is to collect meteorological data in real time through meteorological stations and transmit the data to the irrigation management platform. Meteorological stations are usually composed of rainfall sensors, temperature sensors, humidity sensors and wind speed sensors, which transmit data to the irrigation management platform through wireless or wired communication protocols. In actual implementation, the process of obtaining meteorological data in real time is as follows: First, the meteorological station collects meteorological data in real time through rainfall sensors, temperature sensors, humidity sensors and wind speed sensors. For example, assuming that the current rainfall is 10 mm, the temperature is 25 degrees Celsius, the humidity is 60%, and the wind speed is 3 meters per second; then, the meteorological station transmits these data to the irrigation management platform, and the platform generates corresponding irrigation plans based on these data. For example, assuming that meteorological data shows that there will be heavy rainfall in the next 24 hours, the platform will generate a plan to reduce the amount of irrigation water to avoid water waste caused by repeated irrigation before and after rainfall. By obtaining meteorological data in real time, the irrigation system can adjust the amount of irrigation water in advance according to meteorological changes, avoiding the problem of insufficient or excessive irrigation caused by meteorological changes, and significantly improving irrigation efficiency and crop yield.

[0127] Soil moisture data and nutrient content data are another important basis for generating irrigation plans, mainly including parameters such as soil moisture, soil temperature, nitrogen content, phosphorus content and potassium content.

Flow meters are used to measure irrigation water consumption, and fertilizer injectors are used to measure fertilizer usage. In actual implementation, the process of real-time collection of soil moisture data and nutrient content data, and obtaining irrigation water and fertilizer usage is as follows: First, the soil sensor collects soil moisture data and nutrient content data in real time through the soil moisture sensor, soil temperature sensor and nutrient content sensor. For example, assuming that the current soil moisture is 20%, the soil temperature is 20 degrees Celsius, the nitrogen content is 50 mg / kg, the phosphorus content is 30 mg / kg, and the potassium content is 40 mg / kg; then, the flow meter measures the irrigation water usage in real time, for example, assuming that the current irrigation water usage is 10 cubic meters; the fertilizer injector measures the fertilizer usage in real time, for example, assuming that the current fertilizer usage is 5 kg; then, these data are transmitted to the irrigation management platform, and the platform generates corresponding irrigation plans based on these data. For example, assuming that the soil moisture is lower than the preset threshold, the platform will generate a plan to increase the amount of irrigation water; if the nitrogen content is lower than the preset threshold, the platform will generate a plan to increase the amount of nitrogen fertilizer. By collecting soil moisture data and nutrient content data in real time and obtaining irrigation water and fertilizer usage, the irrigation system can accurately adjust irrigation water and fertilizer usage according to soil conditions and crop needs, avoiding poor crop growth caused by insufficient soil moisture and nutrients, and significantly improving irrigation efficiency and crop yields.
