Description

Technical Field

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

[0002] The multifunctional intelligent water-saving irrigation system represents an important progress in the application of technology and sustainable development in the field of modern agriculture. With the continuous growth of the global population and the gradual emergence of the impact of climate change, traditional agricultural production methods are facing increasingly severe challenges. Among them, water shortage is one of the most prominent problems.

[0003] However, there are still some shortcomings in its 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 judgments and turns irrigation operations on or off 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, the 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 for receiving the irrigation value calculated in the central processing module, and judging the calculated irrigation value and the irrigation threshold, obtaining an instruction, and transmitting 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: used to allow 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; make sure these devices are intact.

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

[0017] Step A4: Insert the monitor vertically at 90 degrees into the soil to be tested. Do not shake the monitor during insertion to prevent the monitor probe from being bent and damaged. Insert the monitor parallel to the soil to be tested for multi-layer soil moisture detection. The humidity heads should be arranged 10 cm apart to prevent mutual interference. Gently insert the monitor into the hole to ensure that the monitor is in full contact with the surrounding soil and remains stable.

[0018] Step A5: Make appropriate connections and fixations according to the monitor model and manufacturer's instructions; ensure that the monitor is placed horizontally to ensure data accuracy.

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

[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 not to care about 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 adjust the water pressure and flow in the irrigation network; according to the requirements of the irrigation strategy, the operating status of the water pump is adjusted in real time to ensure accurate control of the irrigation amount;

[0037] Irrigation network management unit: monitors the operating status of the irrigation network through intelligent valves and monitoring instruments, and promptly detects and handles problems such as pipeline blockage and leakage; optimizes the layout and design of the irrigation network according to the topography and crop layout of the farmland to improve 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, wherein the operating status includes whether the water pump is turned on and the irrigation duration; this real-time monitoring function enables users to grasp the irrigation status of farmland at any time 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 enables users to flexibly adjust irrigation strategies according to their needs or weather conditions to improve irrigation efficiency.
