在导弹作战效能优化实时采集技术问题的研究中,针对半实物仿真系统,准确、实时的数据采集,实现优化系统性能,根据导弹半实物仿真数据来源分散、形式多样、实时性要求高等具体特点,设计了一套实时数据采集系统。实时数据采集系统以通用计算机和VMIC反射内存网络为硬件平台,通过对数据采集实时性优化设计,实现了仿真实时数据的分布与集中管理,完成快速闭路仿真。实验结果表明,实时数据采集系统功能完善、运行稳定,满足了半实物仿真的实时数据采集需求。

In the Hardware-in-the-loop simulation system, accurate and real-time data acquisition is the basic premise of operation simulation. In view of the features in Hardware- in- the- loop simulation of scattered data sources, various forms and higher real-time, this paper designs a real-time acquisition system pertinently. The Real -time data acquisition system takes general computer and VMIC reflective memory network as hardware platform, through the real-time optimal design of acquisition process, the distributed and centralized management of the simulation data acquisition is realized. The results indicate that the real-time data acquisition system is characterized by perfect performance and steadily running and can meet the practical requirements of Hardware-in-the-loop simulation.
