Design And Implementation Of The Temperature And Humidity Monitoring System For Facility Agriculture Based On Wireless Sensor Networks

China is a large agricultural country, and modern agricultural production should be developed. Asan important part of modern agricultural production, facility agriculture should be rapidly developed.Well, in facility agriculture monitoring systems, air and soil temperature and humidity conditions are themost important environmental data. Therefore, we need to enhance the monitoring capabilities, reducethe construction costs, improve the management efficiency and promote the transform ability fromagricultural science to productivity. At the same time, the development of Internet,3G, and wirelesssensor networks technology also provides more technical support for facility agriculture monitoringsystem. Based on this context, this paper designed and realized the monitoring system by integrating thewireless sensor networks and Internet technology.Firstly, the technology of wireless sensor networks for facility agriculture was studied. Thearchitecture included sensor node, sink node and management node. The Network node system includedcommunication protocol, management platform and support platform. The network support technologyincluded the time synchronization technology, location technology, data fusion technology, energymanagement, fault tolerance and data management. Secondly, the technology of Java and Android wasstudied. It included the design method and pattern of UML and MVC, the development technology ofJsp, AJAX, Struts, JDBC, and the module of Android application.A wireless sensor network was set up based on above. It selected the suitable sensor hardwareequipment according to the project need, and realized the service interface of sensor network data. Theneed of temperature and humidity monitoring system was analyzed and a detailed design proposal wasmade, which included overall architecture, HTTP communication model, server and database. Also itgave the design of Web service, mobile system and technique process. At last, a system was developedwith Java and Android, which could meet the need of detailed design.The temperature and humidity monitoring system for facility agriculture based on wireless sensornetworks was the integrated use of WSN, networking and mobile communication technologies. It couldreflect the relevant environmental information of facility agriculture timely and exactly. At the sametime, it had the advantages of energy conservation, accuracy, easily used, low cost, etc. It realized Webservice based on Java. And it could help monitor temperature and humidity information anytime andanywhere.
