The Monitoring System For Agricultural Environment Based On Point Surface Fusion With The Internet Of Things And WebGIS

In recent years,the technology of Internet of things has been widely used in the field of agricultural environment monitoring.The use of networking technology can be monitoring time continuous real-time data acquisition,convenient for us to observe real-time data processing,but in large area monitoring,due to different spatial variability,most IOT sensor data acquisition and diversification of the small scope of data integration,this technology many problems facing the monitoring points distribution design and data visualization etc..The scope for networking of monitoring objects and regional differences in the characteristics,the method proposed in this paper data simulation and evaluation of a regional approach,and designed a set of things will be on the point of the monitoring data and WebGIS on the face of the spatial data fusion analysis solutions.In the aspect of data collection,we use networking sensors to collect the environmental data of farmland,because the range of sensor data networking limitations,we placed more in the planning of the monitoring area network data collection point to complete large area farmland environmental data collection.The ArcGIS visualization technology is applied to the collected data,and the 3D visualization processing is carried out.In the process of processing,the C++ language is used and the 3D visualization class library SDK is introduced,and a supplementary plug-in for ArcGIS software is written.Then the post-processing plug-in is integrated into the ArcGis software to optimize the three-dimensional visualization of the monitoring data.Finally,a set of agricultural environment monitoring system is set up with the integration of the Internet of things monitoring data and the WebGIS spatial data point surface.The system used to achieve data location map display,from the area of simulation and evaluation of regional monitoring,thematic map management 3 main functions.Finally to Jilin province Nong'an county corn field growth monitoring for the case of the application of system analysis,the results show that the system can effectively realize the dynamic regional agricultural environmental monitoring approach,improve the comprehensive ability of maize crop growth monitoring and disaster management for agricultural production,to provide more convenient service for the application.In the area of monitoring and analysis of thematic map visualization,written post-processing plug-ins integrated into ArcGis software can optimize the 3D visualization of monitoring data,the two-dimensional spatial variability of thematic map than the traditional representation of 3D data more natural,more clear and intuitive,which is of great significance to promote the development of modern agriculture.
