The Research Of Smart Agricultural Monitoring System Based On Internet Of Things

The Internet of things as the third wave of information industry,will play an important role in the traditional agriculture to modern agriculture upgrade,and based on the smart of the iot agriculture will be a new pattern of agriculture.The Internet of things technology as technical support of agricultural modernization,its application in agricultural production and scientific research will accelerate the development of modern agriculture.Agricultural environment monitoring as an important part of modern agriculture,is the agricultural environment information and crop growth.In the process of agricultural production,soil temperature,soil humidity,environment temperature,environment humidity,rainfall,wind speed,CO2 concentration,pH value of water environment,and other natural factors mutual influence the growth of crops.Traditional agricultural extensive management way,cannot be achieved in agricultural environment information,intelligent management.In order to improve the traditional agricultural production mode and realize intelligent management of agriculture,this paper research of smart agricultural monitoring system based on Internet of things,the system can realize the agricultural environment of crop growth status and parameters of the real-time monitoring and intelligent management,to improve the efficiency of agricultural production and management.This paper first to the topics background,purpose and significance,and the Internet of things involved in the related concepts and technical analysis is introduced.Based on Internet of architecture,design the system overall structure block diagram.To perceive the node hardware architecture,microcontroller platform,wireless communication module,TDR-3 soil temperature and humidity sensors,SH-300-ND CO2 concentration sensor,E-201-C-9 pH sensors,hikvision high-definition video surveillance cameras,JY-QX environment perception such as small-sized automatic weather station sensor as the core,to build a sensor node hardware.Second,the wireless sensor network gateway was designed and implemented.Gateway is designed on the basis of the processor,by extending the ZigBee module,Wi Fi module,Ethernet module,memory module and power module.Gateway of ZigBee module and sensor nodes in wireless sensor network for data communication and the nodes in a network of management,at the same time using Wi Fi module for wireless data transmission and the Ethernet module for data cable transmission,realize the gateway as the sensor nodes connected with the corresponding functions of the monitoring center.On the wireless sensor network node deployment method,by using the deployment scheme based on regular triangle mesh,maximize the network coverage of a single node,greatly reduce the cost of application.Finally,the system software to carry on the design and implementation,including design of the perception layer of the perception node,the transport layer of the coordinator gateway and application layer of the monitoring center.In the monitoring center software design aspect,through in MyEclipse environment,based on B/S architecture using JAVA and JSP language,completed the overall design of the monitoring center,monitoring center Web server,the monitoring center front desk interface design,serial port communication,the client interact with the database and so on,the system adopts the Tomcat server for the release of information,will the Tomcat server to connect to the Internet at the same time,the user can access anywhere monitoring center,realize information sharing.The system test and operation results show that the research of smart agricultural monitoring system based on Internet of things has the following basic functions:(1)acquisition of farmland environment parameter;(2)can real-time video monitoring conditions for the growth of crops;(3)farmland environment parameter and collected in the crop growth status information can be stored on a Web server,provides the basis for the development of modern agricultural information database;(4)short-range wireless network monitoring node and data transmission;(5)the agricultural management after registration,can login system,on the farmland environment parameter and crop growth status in real-time.Thus it can be seen that the paper work to promote the development of China's agricultural modernization is of great significance.
