摘要
针对大规模复杂仿真系统中分布式数据管理的需求,提出了基于组件的通用数据管理方法.首先对数据操作过程进行抽象,设计了数据操作组件元模型,然后在符合高层体系结构的模式下,对数据操作组件进行了集成.提出了双总线的逻辑结构,将控制信息和数据流分别传输,减少了相互间的干扰.文中提出的数据管理方法已经在实际仿真系统中应用,效果令人满意.
It is presented in the paper the idea of constructing generic data management framework in large-scale complex simulation systems aiming at fulfilling the data requirements of simulation systems. Firstly, the meta-model of data operation is designed based on the abstraction of data operation process, and then the data management integration framework in accordance with HLA is proposed to integrate data components. It is also presented in the paper the dual-bus logic structure, which separates control messages with data flows, thus reducing interference between them. This data management method has been applied in practical simulation systems with satisfactory results.
