Design Of Intelligent Water Saving Irrigation System Based On Mobile Terminal

With the increasing global population,the human demand for water resources is increasing,but the world's only water resources are limited so how to make rational use of water resources and how to save water has become the focus of attention today.In this paper,an intelligent water-saving irrigation system based on mobile terminal is studied,which is mainly used in the scenarios of wide distribution of crop planting,multiple monitoring points and difficult power supply,combining mobile terminal with Narrow-Band Internet of Things(NB-IoT)technology,using high-precision soil temperature and humidity sensor,collecting soil temperature and humidity information and meteorological information on line,It realizes the functions of real-time display of collected infonnation,intelligent selection of irrigation strategy,remote control of irrigation equipment and so on.The main work is divided into the following areas:1.Intelligent water-saving irrigation system design.The structure design of intelligent irrigation system,the design of Information acquisition module of NB-IoT node and the software design of WeChat small program are completed.The hardware part mainly completes the core control board design,the NB-IoT communication module design,the Sensor module design,as well as the photovoltaic power module four part of the circuit design.2.Mobile terminal design.Based on WeChat small program,a simple and easy user interface is designed,because WeChat small program has the advantages of intelligent,flexible,convenient,low cost,so in the software design we use WeChat small program as the user's operating software design.Small programs can be obtained through the mobile phone WeChat scan code,users do not need to install software,through small programs we can do the remote control of field equipment,real-time view of the various environmental data collected by the node,users can do more convenient and efficient management of field environmental information,to achieve timely irrigation of crops,reducing the waste of water resources at the same time increases the yield of crops.3.Irrigation strategy development.The system designed three irrigation modes for manual irrigation,scheduled irrigation and quantitative irrigation.Users can select the appropriate irrigation mode at the mobile terminal as needed.
