摘　　要：为了提高仿真系统在分布、异构等复杂网络环境下的运行效率,以信息服务的实时性和可靠性为着眼点,提出了一种基于Windows NT与实时扩展的仿真系统架构及其实施方案.在该架构中,运用单播和多播的实时仿真以太网,结合半实物接入的需求,实现了基于广播内存网的半实物接入网络.同时为满足仿真信息的实时性要求,构建了基于RTX内存数据库的试验数据库.测试和分析结果表明,该仿真平台具有良好的可靠性和可扩展性,可满足复杂仿真系统对实时性的要求.Fcousing on real-time and reliability of information service, a simulation system architecture and its implementation method based on Windows NT＋RTX were put forward to improve the running efficiency of simulation system under the complex distributing and heterogeneous network environment. In this architecture, the real-time simulation ethernet using RT-TCP and RT-UDP was used to establ;sh semi-physical access network based on broadcasting memory network. At the same time, to meet the need of real-time of simulation information, testing database based on RTX memory database was designed to support information management. Test and analysis results show that the simulation platform possesses better reliability and extensible performances,and meets the requirements of real-time for the complex simulation system.
