Abstract  

Agricultural meteorological stations, as an important part of modern agricultural science and technology systems, are reshaping traditional agricultural production models through multi-source data integration and intelligent analysis technologies. This paper analyzes the core role of agricultural meteorological stations in precision agriculture from four dimensions: technical architecture, functional applications, practical cases, and development trends, and discusses their value in promoting agricultural green transformation.

1. Definition and Functions of Agricultural Meteorological Stations 

1.1 Definition of Agricultural Meteorological Station  

An agricultural meteorological station is an automated observation system that integrates various sensors and data processing technologies. It is primarily used to monitor key meteorological elements such as temperature, humidity, light intensity, rainfall, wind speed and direction, and soil moisture in farmland and surrounding environments. By collecting and analyzing real-time data, it provides scientific support for agricultural production and helps optimize planting decisions. 

1.2 Main Functions of Agricultural Meteorological Stations  

- Real-time Monitoring: Collects microclimate data from the farmland, including temperature, humidity, light intensity, wind speed and direction, and soil moisture.

- Data Analysis: Generates meteorological reports and predictive models through cloud computing and AI technologies to optimize agricultural decisions.

- Intelligent Early Warning: Predicts extreme weather events, such as droughts, floods, and frost, through big data analysis and provides early warnings.

- Precision Management: Supports precision irrigation, variable fertilization, and pest and disease control to improve resource utilization efficiency.

2. Technical Architecture and Core Components of Agricultural Meteorological Stations  

Agricultural meteorological stations adopt a four-layer architecture design: "Perception Layer - Transmission Layer - Platform Layer - Application Layer". 

1. Perception Layer: Integrates high-precision sensors such as temperature and humidity sensors, light sensors, wind speed and direction instruments, and soil moisture sensors.

2. Transmission Layer: Supports LoRa self-organizing networks and 4G/5G communication to ensure real-time remote data transmission.

3. Platform Layer: Built on a cloud computing architecture with PB-level data storage capacity and millisecond-level response speed.

4. Application Layer: Develops intelligent decision-making systems that integrate crop growth models, disaster warning algorithms, and other analytical modules.

3.2 Disaster Prevention and Mitigation  

Early warnings of extreme weather events enable farmers to take effective measures, reducing the economic losses caused by natural disasters. 

3.3 Promoting Precision Agriculture Practices  

Combined with GIS, remote sensing technologies, etc., agricultural meteorological stations support precision irrigation, variable fertilization, and pest control, improving resource utilization efficiency and reducing environmental pollution.

3.4 Supporting Research and Education  

Long-term data accumulation supports agricultural scientific research, reveals the impact of climate change on agriculture, and provides resources for agricultural education.

4. Field Microclimate Meteorological Stations: The Smart Guardian of Precision Agriculture 

Field microclimate meteorological stations are an important part of agricultural meteorological stations, specifically designed to monitor field microclimates. 

4.1 Key Features  

- High-Precision Sensors: Monitors meteorological elements such as temperature, humidity, light intensity, wind speed, and direction.

- Data Support: Provides real-time and historical data queries to help farmers optimize crop management.

- Research Value: Supports agricultural research on the effects of field microclimates on crop growth. 

5. Practical Case: Smart Agriculture Demonstration Park  

A smart agriculture demonstration park utilizes agricultural meteorological station data to achieve intelligent management of irrigation, fertilization, and pest control. Precise control shortens the crop growth cycle, increases yield, reduces the use of chemical fertilizers and pesticides, and improves the safety and market competitiveness of agricultural products. Additionally, the park uses meteorological data to optimize crop planting structures, develop specialty agriculture, and promote agricultural efficiency and farmers' income growth.

- Blockchain Integration: Establishes a credible data recording system for meteorological data, promoting cross-regional data sharing. 

6.2 Key Challenges  

- Data Standardization: Establishing unified meteorological observation standards and data format standards.

- Model Localization: Developing differentiated crop response models for different climate zones.

- Operation and Maintenance Costs: Field equipment has an annual failure rate of about 15%, requiring optimization of maintenance mechanisms. 

6.3 Development Opportunities  

- Policy Support: The "14th Five-Year Plan" proposes building smart farms, with meteorological monitoring equipment included in agricultural machinery purchase subsidies.

- Market Demand: The global precision agriculture market is expected to reach $12.6 billion by 2025.
