分层实时网络结构在仿真中的应用研究

复杂的实时仿真系统中不同层次对实时性要求各不相同.依据仿真数据划分为控制信息和状态信息,提出了运用实时TCP协议进行控制信息传输和使用实时UDP协议进行状态信息传输的实时仿真局域网.针对半实物接入的需求,实现了基于反射内存网的半实物接入网络.在信息传输延迟理论指导下,对两种网络环境进行了实时性分析.结合某武器系统的分布式仿真试验,给出了分层实时网络的设计方案.

Applied Research on Delaminated Real-Time Network Framework in Simulation

Different level requests variously the real-time behavior in the complex real-time simulation system.Simulation data is partitioned into the controlsand status information,so real-time simulation LAN that controls information transmission by using real-time TCP and status information transmission by using real-time UDP is proposed.Aiming at the need of hardware-in-the-loop simulation system,reflective memory networks(RMN) is used.Under the guidance of the theory about delays in the transmission of information,the real-time behaviors of the two kinds of network are analyzed.According to the distributed simulation system of a weapon system,the design of delaminated real-time network framework is also provided.
