Canopy Monitor

Introduction and Principle

Online plant canopy monitoring device is a device used for real-time monitoring of plant canopy status. It uses lens imaging to measure plant canopy data and calculates canopy structure parameters through the measurement of canopy porosity; This is the principle unanimously adopted by various canopy instruments in the world, and this method is precise, labor-saving, time-saving, fast and convenient among all methods. To provide reliable scientific basis for guiding rational fertilization in rural areas and efficient management of modern farms, it is widely used in scientific research and production guidance in agriculture, forestry, plants, and other fields.

Technical specifications

1. Image acquisition:

Acquisition method: Use a movable image collector with a 100 ° wide-angle lens, deployed above the canopy for downward image capture

Resolution: 2592 * 1944

Perspective subdivision: The zenith angle can be divided into ten regions from 0 ° to 75 ° (100 ° wide-angle lens), and the azimuth angle of 360 ° can also be divided into ten regions

2. Photosynthetically active radiation (PAR):

Sensing range: Sensing spectrum 400nm -700nm

Measurement range: 0——2000μmol/㎡•S

3. Canopy analysis host:

Built in system: Built in automatic image analysis and processing system

User interface: Equipped with a 10 inch color touch screen display, supporting historical data viewing, multiple language (Simplified Chinese, English) switching, and content transmission settings.

Color correction: manually adjust HSV color space threshold

4. Monitoring scope:

Coverage area: centered around the canopy analysis host, supporting any point within a range of 30 meters

Canopy height requirement: applicable to plant communities with a canopy height of less than 1.5 meters

5. Collection and transmission:

Time interval: Users can set the collection and transmission interval, with a minimum interval of 1 hour and a maximum interval of 72 hours

Automation: Based on the latitude and longitude information of GPS positioning, automatic collection during the day and automatic pause at night are achieved

6. Data storage and transmission:

Local storage: Provides 20GB of large storage space, sufficient to store historical data and images for over 180 days, and supports exporting through USB interface

Cloud platform: The collected data is automatically uploaded to the cloud based agricultural data center through 4G wireless transmission. Users can access real-time data through a dedicated account and download it in tabular form

7. Energy supply:

Solar energy system: including 200W solar panels and 130Ah colloidal cells to ensure long-term stable power supply; It can also support 220V AC power supply
