Intelligent Remote Monitoring System Of Large Scale Greenhouse

Greenhouse is an important component of modern agriculture,accounting for more and more proportion in agricultural production,and greenhouse monitoring technology is also rising,the most widespread use of which is automated monitoring technology.But present automatic monitoring system,chiefly accomplishing collecting signal,which needs on-site observation and control,can not meet the requirements of large scale greenhouse monitoring,remote monitoring and intelligent monitoring.Based on Iot framework,the intelligent remote monitoring system of large scale greenhouse is designed,and perception and recognition of environment factors,network broad-band communication,data management,and service application are researched.The perception and recognition layer is designed,choosing high-performance sensors,which collect environment information,using Stm32 as main control chip,adopting ZigBee Wireless Sensor Network.Based on the analysis of broadband connection and underlying data,network building layer chooses Udp as transfer protocol,designs communication server by JavaNio,and two logical link of communication,including the data link and control information link.By Java Dbcp,efficiency of font connecting to Mysql is raised obviously.The design of master-slave replication and read-write separation of Mysql accelerates the database access speed and ensures data security.Using segment division and table division methods in the database improve the speed of mass data access.Web server is designed by highly scalable and high stable SpringMvc,and front is designed by Jquery.Web server achieves many functions such as product management,real-time data display,information curve drawing,historical data inquiry,automatic E-mail alarm,on-line forum and so on.
