Design and implementation of agricultural water conservancy intelligent irrigation system based on Internet of Things

Aiming at the key problems of farmland irrigation and achieving the purpose of low cost, high energy saving and intelligent irrigation, this paper designs and researches an intelligent irrigation system for farmland based on Internet of Things (IoT).This system makes use of sensors and information technology in the field of water irrigation in the era of Internet of Things (IoT) to improve the automation level of agricultural irrigation, and it is a new embodiment of intelligent water conservation. Through intelligent monitoring, soil moisture and irrigation volume can be precisely controlled to improve the efficiency of water use, thus achieving the purpose of water conservation and playing an active role in alleviating water shortage and related environmental problems. An intelligent irrigation system needs to design the hardware and software of the system. The hardware design of the system mainly includes the design of the collection node module, gateway node module, control module and wireless transmission module. The aim is to achieve real-time data collection and stability of data transmission; in the system software part, the workflow of each node of the wireless communication network is designed to achieve real-time collection of farmland data and precise irrigation of crops.
