I. Product Introduction

The Corn Northern Leaf Blight Automatic Monitoring and Early Warning System relies on an IoT cloud platform, integrating meteorological and soil analysis modules to automatically collect and process environmental data from corn planting areas. The system includes a built-in disease prediction model that combines corn growth characteristics and environmental data to accurately monitor and forecast the incidence trend of northern leaf blight. It provides farmers with a scientific basis for disease control, reduces yield losses, and promotes the intelligent development of agriculture.

II. Technical Parameters

1. Complies with the GB/T 24689.6-2009 standard (Plant Protection Machinery—Agricultural and Forestry Microclimate Information Collection System).

2. Data processing function: The system automatically generates prediction curves for the probability of northern leaf blight occurrence and simultaneously plots microclimate environmental data curves. By displaying dual curves side by side, users can visually analyze the correlation between environmental factors and the incidence trend of northern leaf blight, providing data support for agricultural research and precise control.

3. Data collection host: Capable of collecting data such as air temperature, air humidity, wind speed, wind direction, light intensity, rainfall, soil temperature, and soil humidity; supports Modbus 485 sensor expansion; includes real-time clock and time calibration functions.

4. Communication method: Supports 4G full-netcom.

5. Power supply method: Supports AC 220V or solar power supply DC 12V (40W, 20Ah solar power system).

6. Device operating power: ≤ 3W.

7. Low power consumption: Can operate continuously for ≥45 days in overcast and rainy conditions.

8. Operating temperature: -20 to 70°C.

9. GPS positioning: Built-in GPS positioning function, allowing users to view device station data on GIS maps.

10. Sensors: Utilizes multi-parameter ultrasonic sensors with high-precision measurement performance, supports operation without wind speed startup limitations, and operates stably under zero wind speed conditions. Offers 360° omnidirectional measurement without angle restrictions, simultaneously capturing wind speed and direction values.

11. Data upload: Default upload frequency is once every 60 minutes, 24 times per day; upload frequency can be adjusted as needed.

12. Remote viewing: Supports remote access via mobile app and web端 to view device information such as online status, signal strength, voltage information, historical data queries, and remaining data usage.

13. Remote maintenance: Enables remote updates via the cloud platform, allowing system maintenance and upgrades without leaving home.

14. Software functions:

(1) Fault alarm: Includes device displacement alarm functionality.

(2) Real-time upload: Monitoring data is uploaded to the cloud platform in real time for backup, ensuring no data loss.

(3) Data query and export: Allows screening of monitoring data by time period as needed. Monitoring data can be viewed and exported in the form of graphs, Excel spreadsheets, etc.

(4) WeChat alerts: Device-related warning information can be pushed to users via WeChat official accounts, enabling timely responses and serving a preventive and early warning role.

(5) Threshold settings: Supports setting thresholds for different sensors to enable data monitoring and alerts.
