| Abstract: |
| 【Objective】The aim of this research was to study automated irrigation control system based on internet of things and improve its application in large planting area.【Method】Acquisition of soil moisture information is realized with ZigBee network,and irrigation decision is made according to collected information.PLC is selected as the core controller.The system has a variety of control modes to control irrigation and keep constant pressure for the first water pipe.It executes commands and monitors while irrigation process is controlled and monitored with PLC and HMI platform.The platform alarms if the system fails.【Result】The automated irrigation control system based on internet of things was designed with friendly interface and convenient operation.More than 50% water was saved compared with furrow irrigation and surge flow irrigation,and water amount,irrigation time and fertilization amount were more accurately controlled.Labor force was saved as well.【Conclusion】A water-saving irrigation system with features of remote monitoring,data sharing,accurate irrigation,intelligent alarm and automatic control was established and could be widely used in large scale planting area. |
