Research And Design On Virtual Simulation System Based On Wireless Sensor Network

With the development and popularity of the virtual simulation and the wsn monitoring, the traditional video surveillance and 2D interactive interface cannot meet the needs of users,such as simplification, 3D visualization and mobility of the system. Therefore, the research and application of 3D virtual interactive system under complex environments become hotspots in the field of virtual simulation technology.The purpose of this paper is to simulate monitoring system that based on SWN by using virtual simulation technology. After analyzing the demand of system functions and database,we design a framework architecture and the underlying database system. Multi-type sensors are deployed in the labrotay to collect various data, then it can achieve the simulation system. The experimental environment is deployed in the room 600 of main building. The main work of this paper are as follows:1.Analyzing and researching the 3D modeling techniques and the model optimization techniques, completing the modeling and optimization of 3D virtual laboratory scene by using Auto CAD and 3ds Max.2.Studying target tracking and trajectory mining techniques based on wireless sensor network. Proposing a multi-target trajectory set connection algorithm based on Mini Tra Mo algorithm according to the characteristics and needs of our system, by which implement two tracks set error-free connection.3.Studying 3D computer graphics on vectors, matrices, crop, transform, ray tracing, collision detection and other mathematical methods, and unity3 d engine architecture, component technology and development of technology.On the basis of the uinty3 d platform, we develop the virtual simulation system of wireless sensor networks using c#. The experiments demonstrate the feasibility of this simulation system, achieve environmental data display, target activity simulation, interactive roaming between users and real world, fire monitoring and simulation etc. Aiming at reducing the complexity of the system operation with more intuitive using of virtual simulation system. Especially, automatic monitoring alarm of abnormal events and roaming interactive features of our system can substantially cut down the user’s workload, and increase the efficiency of monitoring.
