Abstract: This paper proposes a research on time and space consistency problem in HLA bridge multiple federations system. It divides the data forwarded by bridge federate into three data types, defines the corresponding structure of entity class and interaction class, and puts forward three processing methods, the delay compensation method(used to solve delay of entity attributes update), the impact point parallel remove method(used to solve delay of Precision Guidance Weapons(PGW) hit Interactions) and the rollback method(used to solve delay of entity anti-attributes update). Experimental results show the methods can efficiently contents the demand of time and space consistency by practical running of the bridge multiple federations system.

Key words: High Level Architecture(HLA), bridge, multiple federations, time and space consistency

摘要： 针对HLA桥接多联邦系统，提出其时空一致性问题研究。将桥接转发的数据划分为3种数据类型，定义相应的实体类和交互类，给出3种处理方法，其中，延时补偿法解决实体属性更新时的延时，平移命中点法处理精确制导武器爆炸交互时的延时，回滚法面向非精确制导武器爆炸交互时的延时。实验结果表明，该方法可满足桥接多联邦系统中的时空一致性。
