摘要
研究平台级仿真训练系统,广泛应用于武器装备试验评估领域中,平台级仿真包含实体数多、交互信息复杂。如果有人或硬件在回路,则需实现实时运行。如果采用分布式结构,还需实现时钟同步。为了解决实体间复杂信息交互、强实时运行和时钟同步控制等问题,提出参照HLA的数据交互机制和时间推进机制设计了平台级仿真系统框架,并采用流行的Win-dows+RTX平台开发了仿真系统软件。经时间测试,设计的仿真系统满足微秒级的定时精度和死线(dead-line)要求。仿真表明,设计方法适用于平台级、多仿真实体交互,为强实时推进的分布式实时仿真系统构建提供了参考。
Platform-level simulation has applied to weapon equipment test and evaluation besides training. It con- tains a large of entities and intricate interactions. The system must run in real-time if it is the hmnan-in-lonp or hardware-in-loop system. Furthermore, the system must be synchronized if it is distributed. To solve the problem of intricate interactions, strong-real-time running and clock synchronization controlling, the paper designed the platform -level simulation architecture by reference to data-exchange mechanism and time-advancement mechanism in HLA, and developed the simulation system based on Windows+RTX platform. After tested, the system has a good perform- ance in timing precision and real-time control. The design in this paper can be used to construct platform-level, multi-entities interaction, strong-real-time distributed simulation systems.
