摘要
时间一致性是保证分布式仿真系统具有一定置信度的基础,各实时系统仿真时间与物理时间保持同步保证了LVC(真实仿真、虚拟仿真和构造仿真)系统之间交互的因果关系的合理性。提出了异构系统时间自治策略、系统交互的时间戳策略和时钟跟随同步策略,并利用RTX对Windows进行实时性扩展,利用GPS标准秒脉冲的分时方法进行仿真,实现了各异构系统仿真推进时间的同步,并为仿真系统的实时推进以及与真实装设备的实时交互奠定了基础。
The time consistence is the base of the confidence degree of the distributed simulation system. The syn- chronization of simulation time and physical time can make sure that the consequence of the LVC system is rational, This paper brought out some new methods, such as the time autonomy, interaction with time stamps and following clock synchronization. It expended the Windows＇ real-time with RTX, brought out time-subsection based on the standard GPS second impulse, realized the time synchronization of inhomogeneous systems, and facilitated the simula- tion system real-time advance and interaction with real equipment.
