Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation equipment, and particularly to an intelligent water-electricity integrated irrigation interaction method and system. Background Art

[0002] In the current agricultural irrigation system, although the application of automation and intelligent technologies has made remarkable progress, bringing many conveniences and efficiency improvements to agricultural production, this field still faces many deep-seated problems and challenges, especially in the accuracy of irrigation management.

[0003] Traditional irrigation methods, as the cornerstone of agricultural production for a long time, often rely on farmers' empirical judgments or preset timed irrigation plans. In this mode, the irrigation decision-making process lacks scientific data support and dynamic adjustment mechanisms, and it is difficult to accurately reflect the actual demand changes in different irrigation areas. For example, factors such as soil moisture, crop growth stage, weather conditions (such as rainfall, temperature, humidity, wind speed, etc.), and soil type will have a significant impact on irrigation demand, but these factors are often ignored or simplified in traditional irrigation methods.

[0004] Due to the lack of accuracy in irrigation decision-making, irrigation is often carried out when it is not needed, or the irrigation volume is insufficient or excessive when irrigation is needed, resulting in unnecessary consumption of water resources, or affecting the respiration of crop roots due to overly wet soil, and even causing the breeding of pests and diseases. Insufficient or excessive irrigation poses a serious threat to the growth and yield of crops. Insufficient irrigation will cause the crops to lack water, affecting their normal physiological activities and yield formation; while excessive irrigation may cause problems such as oxygen deficiency in crop roots and nutrient loss, which is also not conducive to the healthy growth of crops. Especially during the critical growth periods of crops, such as the flowering period and the fruiting period, the precise control of irrigation volume is particularly important, and a slight deviation may have a significant impact on the yield.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will be described through specific embodiments in conjunction with the accompanying drawings of the present invention.

[0029] As described in the background art, there are currently technical problems of low accuracy in irrigation decision-making and irrigation water volume during agricultural irrigation, resulting in insufficient or excessive irrigation and affecting the growth of crops.

[0030] To solve this technical problem, as Figure 1 shown, an embodiment of the present invention provides an intelligent hydroelectricity-integrated irrigation interaction method. This method includes steps S101-S107.

[0031] S101. Receive the irrigation instruction of the user.

[0032] In the embodiment of this application, the irrigation instruction includes the irrigation area, irrigation time, and irrigation water volume.

[0033] Exemplarily, the irrigation instruction should clearly include the irrigation area (such as specific plots, crop types, etc.), irrigation time (start time and end time or specific time period), and irrigation water volume (expressed in cubic meters, liters, or irrigation duration, etc.). Before receiving the instruction, the system should automatically verify the rationality of the user input, such as checking whether the irrigation time and water volume are within a reasonable range and whether the irrigation area is registered, etc.

[0034] It should be noted that during the agricultural irrigation process, the intelligent irrigation terminal can irrigate the crops according to the set program. Alternatively, the user can also participate in the irrigation process and irrigate the crops according to the user's irrigation instruction.

[0035] Exemplarily, the user can directly operate on the intelligent irrigation terminal, and the intelligent irrigation terminal receives the irrigation instruction input by the user.

[0036] Exemplarily, the user can also communicate with the intelligent irrigation terminal through the user terminal. The intelligent irrigation terminal receives the irrigation instruction sent by the user terminal. Among them, the user terminal can be a PDA, mobile phone, notebook, and other personal intelligent terminals.

[0037] S102. In response to the irrigation instruction, send a data request to the irrigation control center.

[0038] In the embodiments of the present application, the data request is used to request the historical weather data and historical irrigation data of the irrigation area to be sent back.

[0039] Exemplarily, in the embodiments of the present invention, according to the irrigation instruction input by the user, the system can automatically generate a data request, which includes the specific types of data required (historical weather data, historical irrigation data), the time range, and the identifier of the irrigation area. The data request is sent to the irrigation control center through a secure network protocol (such as HTTPS) to ensure the security and integrity of data transmission. According to the urgency of irrigation, different priorities are assigned to the data request to ensure that the data acquisition for critical irrigation tasks is processed first.

[0040] S103. Receive the data response sent by the irrigation control center.

[0041] In the embodiments of the present application, the data response includes the historical weather data and historical irrigation data of the irrigation area.

[0042] Exemplarily, in the embodiments of the present invention, the data response should be in a structured data format (such as JSON, XML), including historical weather data (such as temperature, humidity, rainfall, etc.) and historical irrigation data (such as the time, water volume, and crop response of past irrigation). After receiving the data, the system performs an integrity check to ensure that all the requested data has been correctly returned. The received data is stored in a local database or cloud storage for subsequent analysis and use.

[0043] S104. Based on the data response, check the irrigation instruction and generate multiple irrigation plans.

[0044] As a possible implementation manner, step S104 can be specifically implemented as steps S1041 - S1043.

[0045] S1041. Based on the historical weather data and historical irrigation data in the irrigation response, perform a preliminary estimate to determine the crop water requirement and soil water holding capacity of the irrigation area.

[0046] It should be noted that the embodiments of the present invention can analyze historical rainfall data to understand the average rainfall, seasonal rainfall distribution in the irrigation area, and the occurrence frequency of extreme weather events (such as droughts and floods). Combining historical temperature and humidity data, it evaluates the demand for crop transpiration and the evaporation rate of soil moisture. Considering the influence of solar radiation intensity on soil moisture evaporation and crop water demand. Analyzing historical irrigation records to understand the growth response of crops and the recovery of soil moisture under different irrigation strategies. Through historical data, it understands the change trend of soil moisture after irrigation and the water holding capacity of soils at different depths. According to the crop variety, growth stage, weather conditions, and soil characteristics, a crop water demand model is used to estimate the crop water demand. Through parameters such as soil texture, structure, and organic matter content, it evaluates the field water holding capacity and available water capacity of the soil.

[0047] Exemplarily, the embodiments of the present invention can estimate the daily water demand and total water demand of crops in the current growth stage according to the crop variety, growth stage, historical weather data, and crop water demand model in the irrigation area; estimate the soil water holding capacity according to the soil moisture data and irrigation water volume data in the historical irrigation data.

[0048] In some embodiments, the crop water demand model is determined according to the crop variety and growth stage. The crop water demand models corresponding to each type of crop are different. The water requirements of the same crop are different in different growth stages.

[0049] The embodiments of the present invention can determine the corresponding crop water demand model according to the crop variety; determine the calculated water demand in the current stage according to the growth stage and the crop water demand model; determine the precipitation within a set time period before the current growth stage according to the historical weather data; calculate the daily water demand and total water demand of crops in the current growth stage according to the calculated water demand in the current growth stage and the precipitation within a set time period before the current growth stage.

[0050] The embodiments of the present invention can divide the historical irrigation process into multiple time windows, calculate the soil moisture and irrigation water volume in each time window to obtain the soil moisture change rate for a set water volume during the irrigation process and the soil moisture change rate after irrigation is completed; determine the estimated soil water holding capacity based on the soil moisture change rate for a set water volume during the irrigation process and the soil moisture change rate after irrigation is completed.

[0051] For example, the embodiments of the present invention can perform a weighted sum of the soil moisture change rate for a set water volume during the irrigation process and the soil moisture change rate after irrigation is completed to obtain the soil water holding capacity.

[0052] S1042. Determine the calculated values of the irrigation frequency and irrigation water volume based on the crop water demand and soil water holding capacity in the irrigation area.

[0053] It should be noted that the embodiments of the present invention can determine the number of irrigations according to the crop growth cycle, weather prediction, and soil moisture dynamics to ensure that the crops obtain sufficient water throughout the growth cycle. Using a crop water requirement model or an empirical formula, combined with the crop water demand, soil water holding capacity, and irrigation efficiency, calculate the amount of water required for each irrigation. Considering the losses of the irrigation system (such as pipeline leakage, sprinkler efficiency, etc.), appropriately adjust the irrigation water volume.

[0054] Exemplarily, the embodiments of the present invention can determine the calculated value of the number of irrigations according to the daily water demand and total water demand of the crops in the irrigation area, as well as the soil water holding capacity; based on the calculated value of the number of irrigations and the total water demand, determine the calculated value of the irrigation water volume.

[0055] The embodiments of the present invention can determine the initial number of irrigations according to the daily water demand and total water demand; based on the soil water holding capacity, correct the initial number of irrigations to obtain the calculated value of the number of irrigations. For example, the daily water demand is 1 ton, the total water demand is 3 tons, and the soil water holding capacity is 1.2. Then the initial number of irrigations is 3, and the calculated value of the number of irrigations is 4. Another example, the daily water demand is 1 ton, the total water demand is 3 tons, and the soil water holding capacity is 0.6. Then the initial number of irrigations is 3, and the calculated value of the number of irrigations is 2.

[0056] The embodiments of the present invention can calculate the ratio of the total water demand to the calculated value of the number of irrigations, and based on the ratio, determine the calculated value of the irrigation water volume.

[0057] S1043. Based on the calculated values of the number of irrigations and the irrigation water volume, as well as the irrigation instruction, determine multiple irrigation schemes.

[0058] In some embodiments, the irrigation scheme includes the number of irrigations, irrigation duration, and irrigation water volume.

[0059] It should be noted that the embodiments of the present invention can design multiple irrigation schemes in combination with the irrigation time in the user's irrigation instruction and the specific requirements of the irrigation area (such as crop type, growth stage, soil conditions, etc.). The irrigation scheme should include key parameters such as the number of irrigations, irrigation duration (or irrigation rate), and irrigation water volume. Use optimization algorithms (such as genetic algorithms, simulated annealing, etc.) to further optimize the irrigation scheme to balance crop water demand, irrigation efficiency, and cost-effectiveness. Consider the policy restrictions of water resource management and the actual operating capacity of the irrigation system to conduct a feasibility assessment of the scheme. Present the designed irrigation scheme to the user in the form of charts, lists, or simulation animations to help the user intuitively understand the differences and advantages of each scheme. Provide a scheme comparison tool to allow the user to select the most suitable irrigation scheme according to factors such as crop growth goals, water resource limitations, and economic costs.

[0060] Exemplarily, embodiments of the present invention can perform time adjustment based on the calculated value of the irrigation frequency and the irrigation time in the irrigation instruction to determine multiple combinations, each combination including the irrigation frequency and the irrigation duration for each time; determine the irrigation water volume range based on the calculated value of the irrigation water volume and the irrigation water volume in the irrigation instruction; and determine multiple irrigation schemes based on the multiple combinations and the range of the irrigation water volume.

[0061] S105. Send multiple irrigation schemes to the user.

[0062] Exemplarily, embodiments of the present invention can display multiple irrigation schemes in the form of charts, lists or interactive simulations through the user interface to help the user intuitively understand the differences between each scheme.

[0063] S106. Receive the selection instruction of the user.

[0064] In the embodiments of the present application, the selection instruction includes the target irrigation scheme selected by the user among multiple irrigation schemes.

[0065] Exemplarily, embodiments of the present invention can allow the user to select the target irrigation scheme through simple operations such as clicking and swiping, and receive the confirmation instruction of the user. According to the user's historical selections, crop preferences and irrigation habits, the system can provide personalized irrigation scheme suggestions.

[0066] S107. Irrigate the irrigation area based on the target irrigation scheme in the selection instruction.

[0067] Exemplarily, in embodiments of the present invention, according to the target irrigation scheme selected by the user, the system automatically schedules irrigation equipment such as water pumps and valves to start the irrigation operation. During the irrigation process, the system real-time monitors key parameters such as the soil humidity and the crop growth status of the irrigation area through the sensor network. If any abnormality is found or the user needs to change the irrigation plan, the system should support dynamic adjustment of the irrigation strategy to ensure the optimization of the irrigation effect. Record the detailed information of each irrigation, including the irrigation time, water volume, equipment status and crop response, to provide data support for subsequent analysis and optimization.

[0068] As a possible implementation manner, step S107 can be specifically implemented as steps S1071 - S1075.

[0069] S1071. Obtain the irrigation data during the irrigation process.

[0070] In some embodiments, the irrigation data includes sensor data and water consumption.

[0071] Exemplarily, the sensor data includes soil humidity data, temperature data and light data.

[0072] Exemplarily, soil moisture sensors are installed at different depths in the irrigation area to monitor the changes in soil moisture in real time. Flow sensors are installed at key positions in the irrigation system (such as the pump outlet, irrigation pipeline branches, etc.) to record the real-time water consumption during the irrigation process. Meteorological sensors such as temperature, humidity, wind speed, solar radiation, etc. are used to evaluate the impact of the environment on the irrigation effect. Through the control system of the irrigation system, the start time, end time, irrigation rate, and total water consumption of each irrigation are recorded.

[0073] S1072. Calculate the water consumption and soil moisture change rate of each sub-region based on the irrigation data.

[0074] Exemplarily, the embodiments of the present invention can statistically analyze the water consumption and soil moisture data of each sub-region, calculate the water consumption per unit time and the soil moisture change rate per unit time in each sub-region; based on the water consumption per unit time and the soil moisture change rate per unit time in each sub-region, calculate the soil moisture change rate per unit water volume in each sub-region.

[0075] Exemplarily, the embodiments of the present invention can divide the irrigation area into multiple sub-regions according to the geographical characteristics, crop types, and irrigation requirements of the irrigation area. According to the data of the flow sensor, combined with the layout of the irrigation system and the irrigation strategy, calculate the water consumption of each sub-region. Use the data of the soil moisture sensor to calculate the soil moisture change rate of each sub-region before and after irrigation to evaluate the irrigation effect.

[0076] S1073. Determine the irrigation situation of each sub-region based on the water consumption and soil moisture change rate of each sub-region.

[0077] In some embodiments, the irrigation situation includes a normal state and an abnormal state.

[0078] Exemplarily, the embodiments of the present invention can determine whether the pipeline connection in each sub-region is normal based on the water consumption per unit time.

[0079] Exemplarily, the embodiments of the present invention can determine whether the sensor working state in each sub-region is normal based on the soil moisture change rate per unit time.

[0080] Exemplarily, the embodiments of the present invention can determine whether the irrigation situation in each sub-region is normal based on the soil moisture change rate per unit water volume. If the pipeline connection is normal and the sensor works normally, but the soil moisture change rate per unit water volume is less than the set threshold, it indicates that there is a situation of water resource waste and it is in an abnormal state, and the user needs to check.

[0081] Exemplarily, embodiments of the present invention can determine whether the irrigation of each sub-region has achieved the expected effect according to the preset irrigation target and soil humidity threshold. If the water consumption is within a reasonable range and the soil humidity change rate meets the crop growth requirements, it is determined to be in a normal state. If the water consumption is abnormal (such as too high or too low), or the soil humidity change rate does not meet the expectation (such as excessive waterlogging due to too high humidity, or drought due to too low humidity), it is determined to be in an abnormal state.

[0082] S1074. If a certain sub-region is in an abnormal state, an alarm message is generated.

[0083] In some embodiments, the alarm message includes the location and alarm time of the sub-region in an abnormal state.

[0084] Exemplarily, the content of the alarm message includes the specific location of the sub-region in an abnormal state (such as coordinates, plot number, etc.), alarm time, abnormal type (such as excessive water consumption, too low soil humidity, etc.) and possible cause analysis. Alarm level classification: According to the severity of the abnormal situation, the alarm message is classified into different levels (such as emergency, important, general, etc.) so that users can process it according to the priority.

[0085] S1075. Send the alarm message to the user to prompt the user to handle the irrigation failure.

[0086] Exemplarily, the alarm notification method: The alarm message is sent to the user in real time through mobile phone text messages, emails, APP push, etc. A detailed viewing page of the alarm message is provided, including historical alarm records, alarm trend analysis and treatment suggestions, etc. After receiving the alarm message, the user should check the irrigation system as soon as possible and take corresponding treatment measures according to the actual situation. The system should allow the user to feedback the treatment result so as to further optimize and adjust the irrigation strategy.

[0087] In this way, embodiments of the present invention can prompt the user to handle the irrigation failure through interaction with the user, ensuring normal irrigation.

[0088] Optionally, after step S1071, steps S1076 - S1077 are further included.

[0089] S1076. Based on the soil humidity data, water consumption data, and the irrigation target of the current irrigation process, re-determine the irrigation duration of the current irrigation process.

[0090] It should be noted that during the actual irrigation process, it is necessary to monitor the soil humidity in real time and dynamically adjust the irrigation duration to ensure appropriate irrigation water volume and avoid under-irrigation and over-irrigation.

[0091] Exemplarily, embodiments of the present invention can clarify the main objectives of the current irrigation, such as replenishing the water lost by the crop due to evapotranspiration, promoting the growth of the crop roots, improving the soil structure, etc. According to the crop type, growth stage, weather conditions (such as temperature, humidity, wind speed, solar radiation, etc.) and soil characteristics, specific irrigation target values are determined, such as the target soil moisture range. Analyze the real-time obtained soil moisture data to understand the soil moisture status of the current irrigation area. Compare the soil moisture data with the irrigation target values to evaluate whether it is necessary to adjust the irrigation duration to reach the target soil moisture. Analyze the historical irrigation data and the water consumption data during the current irrigation process to understand the performance and irrigation efficiency of the irrigation system. Considering factors such as the flow rate of the irrigation pump, pipeline losses, and sprinkler efficiency, calculate the actual amount of water irrigated into the soil. Combining the irrigation objectives, soil moisture data, and water consumption data, use an irrigation model or empirical formula to recalculate the irrigation duration. The irrigation duration should ensure that the crop obtains sufficient water while avoiding problems such as water resource waste and soil salinization caused by over-irrigation.

[0092] S1077. Control the operation of the irrigation pump based on the irrigation duration during the current irrigation process.

[0093] Exemplarily, if the operation duration of the pump does not reach the irrigation duration, control the operation of the irrigation pump. If the operation duration of the pump reaches the irrigation duration, control the irrigation pump to stop and end the irrigation.

[0094] Exemplarily, embodiments of the present invention can formulate an irrigation control strategy according to the re-determined irrigation duration, including the start time, operation rate, and stop time of the irrigation pump, etc. Considering the stability and response speed of the irrigation system, ensure that the irrigation control strategy can be accurately executed. Use the control system of the irrigation system to send a control signal to the irrigation pump to start the irrigation process. During the irrigation process, dynamically adjust the operation rate of the irrigation pump according to the real-time obtained soil moisture data and water consumption data to ensure the precise control of the irrigation duration and irrigation amount. When the preset irrigation duration or the target soil moisture is reached, automatically stop the irrigation pump and end the irrigation process. After the irrigation ends, continue to monitor the soil moisture data to evaluate whether the irrigation effect reaches the expected target. If the irrigation effect is not ideal (such as the soil moisture is too high or too low), analyze the reasons and adjust the irrigation strategy for optimization during the next irrigation. Provide feedback on the irrigation effect to the user so that the user can understand the performance of the irrigation system and the water requirements of the crop.

[0095] The present invention provides an intelligent water and electricity integrated irrigation interaction method. When receiving an irrigation instruction from a user, historical weather data and historical irrigation data are obtained through interaction with an irrigation control center. Based on the historical weather data and historical irrigation data, the irrigation instruction is verified, multiple irrigation schemes are determined, and the user is sent to select and determine a target irrigation scheme, and finally irrigation is carried out. In this way, the interaction among the user, the intelligent irrigation terminal and the irrigation control center is realized before irrigation. Through the historical weather data, historical irrigation data and the user's irrigation instruction, the irrigation scheme is comprehensively determined, making the irrigation scheme more adaptable to the actual situation of the irrigation area and improving the accuracy of irrigation decision-making and irrigation water volume in the agricultural irrigation process.

[0096] Optionally, the intelligent water and electricity integrated irrigation interaction method provided by the embodiment of the present invention further includes steps S201-S205.
