Research On Distributed Scene Simulation System Of Virtual Battlefield Environment

With the development of technology, military simulation is playing an increasingly important role. At the same time, more and more techniques in military simulation such as numerical simulation, physical simulation and semi-physical simulation are used to shorten the period of developing production and improve comprehensive performance of new generation weapon systems.Scene simulation technology is introduced to simulate training system and data protocols are defined to realize communication among scene simulation system and other subsystems in this thesis. The vivid and interactive characteristics of scene simulation are exploited to design distributed scene simulation system that is utilized to train combatants and evaluate the performance of weapon systems.The main contents are summarized as follows:(1) Firstly, the functions and characteristics of existing simulate training system are introduced and the limitations and shortcoming are also pointed to determine master design thought of distributed scene simulation system.(2) Secondly, HLA architecture migrates and TCP/IP communication protocols are adapted to link federal members, which achieve real-time data transmission among subsystems.(3) Thirdly, according to the basic principles of modeling, comparison of the three-dimensional modeling tools, targeted using three-dimensional modeling tools to establish the necessary simulation entity model and three-dimensional scene, and optimized the model.(4) Fourthly, visual simulation development ways for comparison, select the real-time visual simulation software Vega and combined with C/C + + language and MFC class library for visual simulation system development, and design the general object oriented software framework of visual simulation system, implements the system of special effects, meter data display, real-time interaction, key technology such as window and freedom viewpoint.(5) Finally, describe the demo environment of visual scene simulation system and demonstrate the system, evaluate the system performance, invite designers to evaluate user experience evaluation, system meet the design personnel of project evaluation and performance verification requirements.The research of this thesis has been applied in simulate training system of aerospace institute. The experiments show that the method proposed in this thesis can achieve a good effect and satisfy the requirement that designers evaluate and validate protocol.
