复杂实时仿真系统运行支撑环境研究

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.

Support Environment of Complex Real-time Simulation System

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 design...
