为提高分布式仿真系统内部有效数据传输效率,满足系统实时性要求,以车辆定位监控仿真系统为问题原型,提出一种基于运行时间支撑系统数据分发管理(RTI-DDM)和套接字(Socket)的双层数据传输模型.该模型一方面利用RTI-DDM来限定传输数据的范围,有效降低系统内部冗余数据的传输;另一方面,利用Socket技术在仿真实体之间建立点对点的直接传输,从而提高系统的运行效率.对比实验结果表明,在相同仿真交互数据量下,该模型相对于传统RTI数据传输模型,数据传输延时平均缩短50%.

To improve the data transmission efficiency of distributed interactive simulation system and fill real-time requirement,taking a vehicle location and monitoring system as simulation prototype,a double-level data transmission model,which based on distributed data management of run-time infrastructure (RTI-DDM) and socket, is constructed:on the one hand,RTI-DDM is used to limit the scope of data transmission,and therefore redundant data transmission of system is reduced;on the other hand,point-to-point direct transport between the entities is established by Socket technology, so as to enhance the operational efficiency.The experimental results show that, compared with the traditional data transmission model based on RTI,this model shortens data transmission delay by 50%on the average,while the amount of interactive simulation data are salne.
