Design And Implementation Of Farmland Information Monitoring System Based On Internet Of Things Technology

The Internet of Things in modern agriculture refers to the collection of data through various sensors and data transmission to monitoring centers to help farmers find problems in a timely manner and accurately identify the locations where problems occur,so that farmers can greatly reduce out-of-home monitoring.Can grasp farmland information in real time.In this paper,through research on a new generation of information technology,an Internet of Things monitoring system for modern agriculture has been constructed,and servers are deployed on a unified cluster of cloud servers to reduce server hardware,network equipment,and maintenance costs.Finally,farmers can pass Mobile phone or personal computer Internet access real-time view of farmland information.The system adopts a modular design concept,which mainly includes three parts: farmland information data acquisition module,data transmission module,and Internet of Things cloud platform.The function of farmland information data collection system is to use various sensors in combination with single-chip microcomputer to collect data.This system uses homemade soil multilayer temperature sensors as an example.Data transmission module is to transmit field data to Internet of Things cloud platform through LAN,WAN and Internet.The main function of the Internet of Things cloud platform is to accept data from the field,and provide farmers with realtime data display and historical data query functions.The main research contents of this article are as follows:(1)Farmland information monitoring system data acquisition module.According to the analysis of the monitoring objects,the monitoring of the soil temperature and humidity,temperature,humidity,soil PH,light intensity and so on.Through the multi-layer soil temperature sensing hardware design,power module design and communication design,the soil temperature data acquisition function was realized.(2)Farmland information monitoring system data transmission module.Through the common near-distance wireless transmission and long-distance wireless transmission technology,the system adopts ZigBee+GPRS technology.Through the ZigBee close-range networking,sensors in its network range can be aggregated into the ZigBee coordinator,and then the Internet of Things cloud platform can be transmitted through the GPRS network.(3)Farmland information monitoring system Internet of Things cloud platform.According to the analysis of the evolution of the website system architecture,it was determined that the Internet of Things cloud platform adopts the SOA architecture,and through the introduction of SSM,Dubbo,Redis and other technologies,the system architecture of the Internet of Things cloud platform is determined.The Internet of Things cloud platform has designed a single sign-on module,data center module,content center module,search content module and background management module.Because of limited personal energy,the single sign-on function of the Internet of Things cloud platform,the data center data acceptance function,data real-time display and historical data query functions are realized.The Internet of Things cloud platform's web page is based on the Bootstrap framework,using CSS,JS,AJAX and other technologies.The data is displayed using the Baidu open source framework Echarts.A common load balancing solution was introduced and Nignx was used as the Internet of Things cloud platform load balancing solution.Designed a database structure with good scalability,and used MySQL database to store data.Later,MySQL cluster can be used to implement large-scale data storage.
