摘　　要：复杂实时仿真系统中不同层次对实时性、可靠性要求各不相同。网络和信息服务是该类仿真支撑环境的重要组成部分。依据仿真数据划分为控制和状态信息,提出了运用单播和多播的实时仿真以太网。针对半实物接入的需求,实现了基于广播内存网的半实物接入网络。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。测试了各层面的实时性,分析了层面间的实时性约束。结合某武器系统的仿真试验,给出了具体的设计方案,满足了应用中不同实时性的要求。Different level has different requirement for real -time behavior and reliability in complex real -time simulation system. Networks and information service are important components for this kind of supporting environment. Simulation data was partitioned into the control and status information, so real - time simulation Ethernet using RT - TCP and RT - UDP were proposed. Aiming at the need of hardware - in - the - loop simulation system, broadcast memory network was used. Testing database based on RTX memory database was designed to support information management. Real - time behaviors of these parts above were tested, and the real - time restrict between them was analyzed. According to the simulation system of a weapon system, a specific blue print, which satisfies different real -time requirements in the practical application, was also provided.
