The Development of the Simulation Training.System in Complicated Electromagnetic Circumstance

针对模拟复杂电磁环境下的装备训练及联动操作,设计与实现了一种将虚拟现实技术与分布式仿真技术相结合的模拟训练系统。采用分布式虚拟仿真技术实现了整个武器系统之间的交互与联动,完成了从单个战车内成员的单独操作训练到全武器系统综合作战演练的全过程。针对几类典型电磁干扰,设计了一系列训练中使用的电磁干扰策略,给出了电磁干扰的模拟方式。采用"虚实结合"的思想,利用仿真实物键盘配合眼镜式显示屏的方式,建立了训练操作的虚拟现实环境,具有较高的沉浸感。实际的训练操作表明,系统能够满足日常操作训练及模拟特殊电磁环境下的训练需求。

In order to simulate the training and joint operation of the weapons in complicated electromagnetic circumstance, a training simulation system combining the technologies of virtual reality and distributed simulation is implemented.The interaction and joint operation of the whole weapon system,as well as the all processes containing the single operation of one tank and the comprehensive training of the full weapon system,are firstly implemented by the distributed Simulation technology.Then,related strategies and simulation modes for several typical electromagnetism interferences arc proposed. Finally,a virtual reality environment with high sense of immersion is established,which is on the basis of'the combination of the virtuality and reality'and the adoption of simulated physical keyboard with eyeglasses.Simulation results show that the system can satisfy the need of training under generic and some special environments.
