摘要 分析了基于HLA的仿真系统中记录与回放结构,研究了联邦执行时仿真数据的记录范围和方法。通过将联邦执行时各种对象类和交互类数据存储在数据库对应的表中,提高了回放时对数据的检索效率。比较了在线回放和离线回放方式,并从实现方法上对在线回放进行了研究。针对仿真演练时各联邦成员的时间推进方式,提出了回放时各邦员间的同步方法。 The architectures of data logging and replay in HLA-based simulation system were analyzed. The scope and methods of simulation data logging during federation execution were researched. By storing simulation data into different tables in a database according to the different object classes and interaction classes, the efficiency of data searching was improved. Comparisons were made between the methods of online replay and offiine replay, and the way of implementing online replay was presented in detail. According to the methods of federates' logical time advancement during excise, the way for synchrony of federates during replay were proposed.
