摘　　要：针对采用异构层次网络架构构建的作战试验测试通信网络在采集试验数据时,由于缺乏全局范围内的时间同步机制导致试验后数据回放过程中出现时间偏差的问题,分析了作战试验异构层次网络独有的特性,给出了作战试验网络的拓扑结构,在此基础上,进一步分析设计了作战试验测试数据回放时间偏差机理与模型,并提出了基于最优划分的时延修正方法和基于虚拟时钟的数据回放控制方法,为保证试验后周期大数据回放与分析处理的精确性提供了一种解决方法。Aiming at the problem of time deviation in post-test data playback process caused by the lack of global time synchronization mechanism in the operational tests communication network constructed with heterogeneous hierarchical network architecture,the unique characteristics of the heteroge-neous hierarchical network of operational tests were analyzed,with topological structure of operational tests given,and with the mechanism and model of the playback time deviation for operational tests data presented.On the basis of that,the time deviation mechanism and model for the combat test data playback were further analyzed and designed,with a delay correction method based on optimal division and a data playback control method based on virtual clock proposed,providing a solution to ensure the accuracy of the post-test cycle big data playback and analysis processing.
