Research on and Realization of Interactive Wireless Monitoring and Management System of Processed Grain Based on Web3D

In order to improve fineness and visualization of processed grain storage monitoring and management process, this paper proposes and realizes an interactive monitoring system based on Web3D. With Web3D, database and user's instructions, 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. The system can also show the three-dimensional scene from multi-perspective realizing 3D visualization of monitoring process. 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. 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.
