Abstract:

Live combat training simulates the process of weapon attack and damage based on real military installation. Its essence is multi-platform distributed real-time simulation， and time unity is the primary basis. Based on time unified demand of real combat training， fully considering the training process， information transmission and time basis of platforms， this paper develops time unified technical research. The time unity design is mainly designed from two levels of participation platform time synchronization and training information time alignment， and time consistency verification is carried out periodically to enhance the system robustness and consolidate the foundation of time unity. In this way， the time of whole process and cross-domain multi-platform distributed real combat training can be unified.

Key words: live combat training, time unity, platform time synchronization, information time alignment, time consistency check

摘要：

实兵交战训练是以参训装备为基础平台，模拟武器攻击、命中毁伤过程的实战化军事训练，其本质是多平台分布式实时仿真，时间统一是其首要基础。针对实兵交战训练时间统一需求，充分考虑训练运行流程、信息传输情况，以及参训平台时间基础，开展时间统一技术研究；主要从参训平台时间同步与训练信息时间对齐2个层面进行时间统一设计，并周期进行时间一致性校验以增强鲁棒性，从而形成实兵交战训练应用层时间统一技术方案，高可靠满足实兵交战训练全流程时间统一需求。
