Internet And Gprs Technology-based Greenhouse Remote Monitoring System

With the development of the technique in electronics and information in recent years, the technique in agricultural greenhouse are using more and more automation and information techniques. Based on this, this thesis researches on the amalgamation technique between control network and information network. For actual requirement of agricultural research, greenhouse field control network and Internet are connected in the greenhouse remote control system based on Internet.Remote control technique results from the spread of network control. The approach of broaden the control network is coming from the existing information network. This thesis analyzes the realization mode of amalgamation control network and information network and on basis of this, RS-485 is picked as field bus to the remote monitoring system with connection with Internet.Aimed at the characteristics of decentralization and having some trouble with laying the special network in the greenhouse field, GPRS mobile communication module is selected to realize the amalgamation between greenhouse field monitoring network and Internet.On analyzing the requirement of greenhouse environment remote control system, this thesis designs a system to manage large numbers of greenhouses. And considering the development trend of information and intelligence, this thesis designs a network structure combined with information management system.Based on the research above, this thesis develops an environment remote monitoring system for greenhouse with GPRS and Web. This system has C/S and B/S twofold modes, and operates on Web Server. Thesystem makes it easier for agricultural science researchers to do research in greenhouse.
