Background

Smart agricultural irrigation system combines 4G/3G/NB-IoT network and automatic control technology to implement precision irrigation, based on actual water requirement of crops and information technology to improve irrigation accuracy. The system can automatically sense when and how long the irrigation is needed. Not only the Smart agricultural irrigation system can improve the utilization rate of water resources and alleviate the contradiction of increasingly tense water resources, but also increase the crop yield and reduce the cost of agricultural products.

Wlink Solution

Equipping with WLINK 4G/3G/NB-IoT modem \ RTU enable the system send farm meteorological data and soil moisture data to the data center over wireless network. The data center will analyze the data and compare it with the special irrigation threshold. When data is up to irrigation threshold, the data center will send irrigation command to WLINK Cellular Modem \ RTU to turn on solenoid valves and startup the pump to irrigate the crops according to the preset irrigation mode. 

Features

Usually, the smart irrigation system includes Data Acquisition, irrigation control, wireless communication, data processing and fault detection features.

1. Data Acquisition

The automatic weather station and the soil moisture sensor regularly acquire data

2. Irrigation Control

By controlling the solenoid valve to start and stop the pump to achieve various irrigation modes such as automatic irrigation, timing irrigation, periodic irrigation and manual irrigation.

3. Cellular Data Communication

Using WLINK 4G/3G/NB-IoT modem/RTU to send meteorological and soil moisture data to data center over mobile network, and also provide data transmission channel to remotely control solenoid valves in data center.

4. Data Processing

4.1 System setup

Configure data acquisition period, acquisition interval, system execution conditions and other parameters.

4.2 Data display and printing

The collected data can be displayed in real time, and can be expressed by charts and print operations.

4.3 Send Control Command

The command will be sent to the data acquisition control module through the 4G/3G/NB-IoT module to control the on/off the solenoid valves. 

4.4 Automatic irrigation

The irrigation work is automatically implemented when the system value reaches the preset Irrigation threshold.

5. Failure alarm

Once the irrigation system fails, such as a water pipe rupture, zero water pressure, sensor, motor or solenoid valve failure, the fault warning light will flash and the alarm will beep. The solenoid valve will close and the pump will stop running immediately.

6. Video Surveillance

Remotely monitor the irrigation process and crop growth through video.

Benefits

1. A variety of irrigation modes are selectable according to specific conditions of construction area. It might maximize the utilization rate of irrigation water.

2. With 4G/3G/NB-IoT wireless network technology, remote monitoring of irrigation has been realized, which might reduce work intensity.

3. Data Processing and Analysis System can make quantitative evaluation for water demand information according to different crops in different growing stages and in different areas. 

4. Precisely control irrigation water and save water.
