Background

The smart agricultural irrigation system leverages 4G/3G/NB-IoT connectivity combined with automated control technology to deliver precision irrigation. By monitoring real-time data on crop water requirements, weather conditions, and soil moisture levels, the system accurately determines when and how long to irrigate. This approach not only enhances water resource utilization and addresses water scarcity challenges but also increases crop yield and reduces overall production costs.

Wlink Solution

WLINK’s solution integrates a 4G/3G/NB-IoT modem and RTU to wirelessly transmit farm meteorological and soil moisture data to a centralized data center. The data center processes this information and compares it with predefined irrigation thresholds. When the data indicates that irrigation is needed, a command is sent to the WLINK Cellular Modem/RTU to activate the solenoid valves and start the pump according to preset irrigation schedules.

Features

The smart irrigation system includes several key components:

1. Data Acquisition

• Sensor Integration:
       Automatic weather stations and soil moisture sensors continuously gather essential environmental data.

2. Irrigation Control

• Automated Operations:
       By controlling solenoid valves, the system manages pump operation to support various irrigation modes, including automatic, scheduled,  periodic, and manual.

3. Cellular Data Communication

• Robust Connectivity:
       The WLINK 4G/3G/NB-IoT modem/RTU transmits sensor data to the data center and provides a secure channel for remote control of irrigation equipment.

4. Data Processing

• System Configuration:
       Operators can set data acquisition intervals, system execution parameters,      and other operational conditions.

• Real-Time Display:
       Collected data is presented in real time via charts and reports, allowing      for immediate analysis.

• Remote Command      Execution:
       Control commands are relayed to the irrigation system via the cellular      module, managing the on/off status of the solenoid valves.

• Automated Irrigation:
       Irrigation is triggered automatically when sensor readings meet or exceed      the preset thresholds.

Benefits

• Customizable Irrigation Modes:
       Multiple irrigation strategies can be tailored to suit specific field conditions, maximizing water efficiency.

• Remote Monitoring and Control:
       Cellular connectivity enables remote management, reducing manual labor and streamlining operations.

• Data-Driven Management:
       Advanced data processing provides quantitative insights into water demand for different crops at various growth stages.

• Water Conservation:
       Precision control ensures that only the necessary amount of water is used, significantly reducing waste.
