With the rapid development of agricultural IoT, smart irrigation is becoming an important technical means to improve the efficiency of agricultural water resources utilization and achieve precision irrigation. The complete intelligent irrigation system is composed of various sensing devices and background management software platforms, which can realize the monitoring and precise control of the entire irrigation area, and greatly improve the efficiency and yield of agricultural irrigation.
1. Field equipment in irrigation areas
a) Telemetry monitoring terminal RTU
This is the core equipment to realize on-site data acquisition and remote control, and mainly has the following functions:
1.Collect data from a variety of sensors, including soil moisture, temperature, EC conductivity, illumination, and more.
2.Control the start and stop status of water pumps, solenoid valves, automatic adjustment devices, etc. according to the instructions.
3.Transmit data to the background server through 4G, WiFi, etc.
4.Local data storage is supported to ensure data security.
5.Remote firmware upgrade is supported.
6.Industrial-grade design, IP65 protection level.
b) Soil moisture sensors.
These sensors are mainly buried in the soil in the root zone and measure the soil moisture content at different levels to determine the timing of irrigation. Common types include:
1.Capacitive soil moisture sensor: Uses the dielectric constant of the medium to measure the soil moisture content.
2.Resistive Soil Moisture Sensor: Determines soil moisture by using changes in soil conductivity.
3.Thermal pulse soil moisture sensor: Soil moisture is determined by the time difference between the propagation time of the thermal pulse in wet and dry soils.
c) Soil temperature sensors.
Measure the temperature change of different soil layers, which is used to analyze the soil thermal environment and judge the crop growth environment. Commonly used sensors include thermistor type, thermocouple type, etc.
4) Soil conductivity sensors.
The conductivity of the soil solution is tested to reflect the soil salt content, which is used to judge the soil quality and irrigation water quality. Generally, an electrode probe is inserted into the ground for direct measurement.
5) Meteorological and environmental monitoring equipment.
It includes parameters to measure air temperature, humidity, light, rainfall, etc., which is used to analyze the local climate environment and irrigation demand.
2. Intelligent irrigation area management and control software platform
The platform realizes the unified monitoring and management of the entire irrigation area, and has the following functions:
1.Data receiving and display: Receiving the data of each measurement point equipment and displaying the distribution in real time.
2.Multi-factor analysis: Correlation analysis of multi-dimensional data such as soil and meteorology.
3.Irrigation suggestion: Intelligently determine the current irrigation demand of each area based on the data.
4.Automatic control: turn on the corresponding pump for irrigation according to demand.
5.Irrigation History: Keep a detailed record of each irrigation for easy reference.
6.Equipment monitoring: monitor the operation status of each equipment, and give an alarm when there is a fault.
7.User management: Users with different permissions can view and manipulate different data.
8.Mobile app control: Users can view and operate monitoring information through the mobile app.
9.Open interface: support docking with other agricultural management systems.
Third, the effect of system application
This set of intelligent irrigation solutions integrates the trinity of sensor network, industrial control system and management software, which can realize the refined management of the entire irrigation area, and has the following application effects:
1.More scientific and reasonable irrigation formulation, based on multi-parameter real-time calculation of the accurate water consumption of each area.
2.More timely and efficient irrigation operations, automatic optimal allocation and scheduling of water resources.
3.More precise irrigation control for precise watering of different crops at different stages of growth.
4.Lower water and labor costs reduce agricultural irrigation operating expenses.
5.Safer and more environmentally friendly crop production, reducing the use of chemical fertilizers and pesticides.
6.Smarter and more convenient management, centralized control and mobile monitoring to improve efficiency.
7.Higher unit yield, effectively improve the efficiency of agricultural production.
Through the application of this set of solutions, the informatization, automation and intelligence of agricultural irrigation can be fully realized, so that the utilization of agricultural water resources can be optimized and the sustainable development of agriculture can be realized. It is suitable for all kinds of large-scale planting and breeding farms, and is an important part of the construction of modern digital agriculture, and its promotion and application have broad prospects.
