Research On And Realization Of Three-dimensional Reconfigurable Interactive Wireless Monitoring And Management System Of Processed Grain

Grain storage is related to the national development strategy,sustained and steady development of social economy and people's daily life,therefore,establishing a well grain storage system has attracted more and more attention,and has got support over the world.Grain storage system has an important strategic position especially in our country.Processed grain storage is an important part of grain storage system,because of its rapid transformation ability of the food to deal with kinds of public emergency,attracted great attention of the government.The government strengthen the construction of system of contingency storage of grain products in recent years.Compared to raw grain,processed grain has worse stability,higher requirements of safety index,faster frequency of exchange,more difficulties in operating.Therefore the research on scientific management monitoring method of processed grain has important practical significance according to the characteristics of the processed grain.In order to improve fineness and visualization of processed grain storage monitoring and management process,this paper proposes and realizes a three-dimensional reconfigurable interactive wireless monitoring and management system.three-dimensional reconfigurable interactive wireless monitoring and management system of processed grain use Browser/Server system framework to realize the three-dimensional visualization of processed grain warehouse remote monitoring.Major research paper are as follows:1.The server background service program parses and stores data which is collected by the data transmission terminal from the wireless sensor network(WSN)to the database.With user's instructions and background data,the system can vividly achieve interactive three-dimensional virtual scene of processed grain storage monitoring,rendering scenes including the spatial location of grain and wireless sensor nodes,relevant storage and monitoring information,and wireless sensor network state information in real time dynamically,through communicating and transferring data with three dimensional reconfigurable storage monitoring display platform.The system can also show the three-dimensional scene from multi-perspective realizing 3D visualization of monitoring process,and can help the staff locate the dangerous position quickly to take timely measures to improve the management efficiency,save labor cost and improve the quality of processed grain.2.In addition,the system provides a tool capable of combining the heat and mass transfer mathematical model of grain bulk with the actual measurement data from the backend storage to simulate the temperature and humidity field of processed grain in different colors in the three-dimensional monitoring scenario with view to help regulators accurately assess food safety status,and test the accuracy and compatibility of the heat and mass transfer mathematical model in actual storage applications.3.This system provides customizable 3D model library.By using the unified data interface and adding the appropriate 3D model,the user may establish environment monitoring systems applicable to storage of vegetables,fruits and medicine,etc.This new monitoring system will represent the development trend of storage monitoring system.
