Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation and intelligent control systems, and more particularly to a multifunctional intelligent water-saving irrigation system. Background Art

[0002] The multifunctional, intelligent, water-saving irrigation system represents a significant advancement in technological application and sustainable development in modern agriculture. With the growing global population and the impacts of climate change, traditional agricultural production methods face increasingly severe challenges, with water scarcity being a particularly prominent issue.

[0003] However, it still has some shortcomings in actual use. For example, traditional irrigation methods often rely on fixed schedules or rough empirical judgments, resulting in waste of water resources and imbalance in the farmland environment. Traditional Internet of Things technology uses weather forecasts to implement weather information judgment and turn on or off irrigation operations based on weather information, which can save irrigation water when there is sufficient rain. Therefore, a multifunctional intelligent water-saving irrigation system came into being. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a multifunctional intelligent water-saving irrigation system to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] Data acquisition module: used to collect soil parameters using a soil monitoring instrument and transmit the collected soil parameters to the data processing module for processing;

[0007] Data processing module: used to clean the collected data and transmit the cleaned data to the central processing module;

[0008] Central processing module: used to analyze and calculate the cleaned data to obtain the irrigation value, and transmit the irrigation value to the judgment module for judgment;

[0009] Judgment module: used to receive the irrigation value calculated by the central processing module, and judge the calculated irrigation value with the irrigation threshold, obtain an instruction, and transmit the instruction to the judgment module;

[0010] Control module: used to receive the instructions determined by the judgment module and perform operations according to the instructions;

[0011] Irrigation execution module: used to perform irrigation operations on farmland;

[0012] Remote monitoring and control module: allows users to view the operating status of the irrigation system and farmland environmental parameters in real time through remote devices.

[0013] Preferably, in the data acquisition module, the installation method of the soil monitoring instrument is specifically as follows:

[0014] Step A1: Select farmland sites as monitoring points according to actual needs;

[0015] Step A2: Prepare the necessary soil moisture monitoring equipment and installation tools, including soil monitors, data loggers, cables, and batteries; ensure that these devices are intact.

[0016] Step A3: Use a drill to prepare measurement holes. The depth of the holes should be determined according to monitoring needs. Usually, holes of different depths can be selected to obtain soil data from multiple layers. Ensure that the diameter and depth of the holes are sufficient to accommodate the monitoring instrument and prevent soil collapse.

[0017] Step A4: Insert the monitor vertically 90 degrees into the soil to be tested. Do not shake the monitor during insertion to prevent bending and damaging the probe. Insert the monitor parallel to the soil to be tested. For multi-layer soil moisture detection, arrange the moisture probes 10 cm apart to prevent mutual interference. Gently insert the monitor into the hole, ensuring full contact with the surrounding soil and keeping it secure.

[0018] Step A5: Connect and secure the monitor according to the monitor model and manufacturer's instructions; ensure the monitor is placed horizontally to ensure data accuracy.

[0019] Connect the cable and data collector: Connect the monitor and data collector with a cable; ensure that the cable is firmly connected to avoid loosening or disconnection; at the same time, connect the data collector to the power supply to ensure normal power supply of the equipment.

[0020] Step A6: After completing the equipment installation, start the data logger and ensure that the equipment begins to record soil moisture data; regularly collect and store data, and use appropriate software or tools to analyze and interpret the data; perform appropriate data processing and result interpretation based on monitoring objectives and needs.

[0023] The standard deviation method is used to detect outliers. The calculation method of the standard deviation is as follows:

[0024] ,in, Expressed as standard deviation, Expressed as mean, represents the value of each data point, and N represents the number of data points;

[0025] The specific method for calculating the mean is:

[0026] ,in, Expressed as mean, represents the value of each data point, and N represents the number of data points;

[0027] According to the characteristics and requirements of the data, a threshold is selected, which is the mean plus or minus 2 times the standard deviation. If a data point is less than 2 times the standard deviation, then this data point is considered an outlier. If a data point is greater than the mean plus the threshold, then this data point is considered an outlier.

[0028] Delete the detected outliers.

[0029] The specific method of filling missing values ​​is:

[0030] The outliers removed in the outlier detection step are used to supplement the missing values. The missing values ​​are supplemented by sorting the collected soil data from large to small and taking the median to supplement the missing values.

[0032] , where G represents the irrigation value, T represents the soil temperature, P represents the soil pH value, D represents the soil moisture, and E represents the soil electrical conductivity.

[0033] Preferably, in the judgment module, if the irrigation value calculated in the central processing module is greater than the preset irrigation threshold, an irrigation instruction is output; if the irrigation value calculated in the central processing module is less than the preset irrigation threshold, an irrigation instruction is output.

[0034] Preferably, in the control module, if the instruction received from the judgment module is an instruction requiring irrigation, the irrigation operation is performed; if the instruction received from the judgment module is an instruction to ignore the instruction, no operation is performed.

[0035] Preferably, the irrigation execution module includes the following units:

[0036] Water pump control unit: The central control unit drives the water pump to start or stop through control signals to regulate the water pressure and flow in the irrigation network. It adjusts the operating status of the water pump in real time according to the requirements of the irrigation strategy to ensure accurate control of the irrigation amount.

[0037] Irrigation network management unit: This unit monitors the operating status of the irrigation network through intelligent valves and monitors, promptly identifying and addressing problems such as pipe blockages and leaks. It also optimizes the layout and design of the irrigation network based on the farmland's topography and crop layout, thereby improving irrigation efficiency.

[0038] Preferably, in the remote monitoring and control module, users can obtain key data such as soil moisture, temperature, rainfall, wind speed, and the operating status of irrigation equipment in real time through a dedicated application and web interface, where the operating status includes whether the water pump is on and the irrigation duration. This real-time monitoring function allows users to keep abreast of the irrigation conditions of the farmland and make timely adjustments.

[0039] In addition to real-time monitoring, the remote monitoring and control module also provides remote control functions; users can remotely control the irrigation system through remote devices, including starting or stopping irrigation, adjusting irrigation volume, and setting irrigation time; this remote control function allows users to flexibly adjust irrigation strategies according to their needs or weather conditions to improve irrigation efficiency.
