The Design Of Farmland Environmental Information Monitoring Platform Based On WebGIS

With the development of agricultural modernization,and agricultural demand for the change from coarse to fine day by day.Speeding up the construction of agricultural information and promoting agricultural intelligent management are important to the development of agriculture and national economy.The geographic information system,remote sensing technology,global positioning system technology is increasingly mature and the associated with the development of agriculture.Agricultural information management also followed the frontiers of technology,development of multidimensional,time accuracy and position accuracy.By using these advanced technology combined with modern mature broadband network technology,to integrate all the information required by coherent agricultural expert decision for guiding the development direction of modern agriculture,make agriculture is striding toward the automated,large-scale,intelligent.In this thesis,the farmland information data acquisition of wireless sensor network and GIS technology at home and abroad research status are introduced in summary.According to the actual situation of experimental design,the overall design scheme of the farmland environment information monitoring system based on WebGIS has been developed,and the main hardware system and software program are introduced in detail.The main design of the hardware is the data acquisition and transmission module.Data acquisition takes the ZigBee technology as the core to construct the wireless sensor network,at the same time,the selection of various sensors is given.Wireless transmission module gives a comparison of different ways of wireless transmission,and ultimately determine the GPRS transmission system.Software system platform is the key content of this design.Through the existing GIS software and technology comparison,the final choice of the ArcGIS Server as a service to map publishing platform.The spatial database of ArcGIS platform and the attribute database based on Server SQL are established,and the connection of different data is realized.Finally,combined with the Microsoft Visual Studio 2010 software platform to build the farmland environment monitoring platform,to achieve a comprehensive search of data acquisition,query time,real-time display of the data,a chart of the data change trend display analysis and basic GIS operations.To provide users with an intuitive and effective visual information platform for the users to provide support in agricultural information management and decision-making.
