空间任务论证仿真系统中异类RTI连接技术研究

Research on connecting heterogeneous RTIs in space mission simulation system

为使空间任务论证仿真系统具有可重用性和扩展性,将异类运行支撑环境(runtime infrastructure,RTI)连接技术引入其中,使其能够在不同任务的论证过程中使用已有的联邦成员。通过分析高层体系结构(high level architecture,HLA)在该系统中的应用关键技术,以及基于桥接盟员和异类RTI的概念,设计并实现了桥接软件以连接采用不同RTI建立的联邦成员,从而能够快速构建针对不同任务的空间任务论证仿真系统。对桥接软件的时间推进请求响应速度进行了测试,实验结果表明该桥接软件高效且可行。

To improve the reusability and scalability of the space mission simulation system, heterogeneous runtime infrastruc- ture （RTI） interconnection method is adopted, so the federates constructed in previous mission simulations is reused. Through the analysis of the key techniques of high level architecture （HLA） applied in this system, and also based on the concepts of bridge federate and heterogeneous RTIs, an application is designed and implemented to connect federates of different RTIs in or der to make this system flexible. Then, the time advance velocity is tested and the result proves that the bridge is qualified for use.
