Data Distribution Management of Flight Simulation Based on HLA/RTI

在基于HLA/RTI的大规模交互仿真中,如何高效地实现数据分发管理的信息交互和传递机制是分布式交互仿真的重要内容.介绍了HLA仿真中的联邦开发和执行过程模型和数据分发管理,提出了一种新的数据分发管理算法,并阐述了该算法的理论和具体实现方法.通过分析采用该算法的数据分发管理仿真系统,证明该算法有效的提高了数据过滤效率,从而缩短系统仿真时间.

In the big-scale interactive simulation based on HLA/RTI, how to establish information exchange and delivery mechanism of Data Distribution Management （DDM） effectively, has become an important content of distributed interactive simulation. This paper introduces Federation Develpoment and Execute Process Model （FEDEP） and DDM in the simulation of HLA, and then a new DDM algorithm is proposed. Tiae theory and the speeitic implementations of algorithrn were presented, ased on analyzing the simulation system with the DDM algorithm. The result shows that the algorithm could improve data filtering rate effectively, accordingly shorten the simulation time.
