一种接收仿真数据的通用高层体系结构的接口研究

General interface of high level architecture for receiving simulation data

为提高基于高层体系结构的仿真工具的通用性,在分析高层体系结构接口数据流程的基础上,提出了一种通用的高层体系结构接口模型。该模型建立了一种通用的高层体系结构接口数据表示、存储和访问的方法,实现了对象类属性的动态订购和反射。此外,利用联邦对象模型文档自动解析技术,实现联邦对象模型信息动态获取,减少了高层体系结构接口代码中仿真应用与运行时间框架之间的静态连接,实现了仿真应用与运行时间框架之间的松耦合。最后,以虚拟样机可视化虚拟环境的高层体系结构接口开发为例,验证了该高层体系结构接口模型的有效性。

To improve generality of High Level Architecture （HLA） based simulation tools, a general HLA interface was proposed by analyzing data flow of the HLA interface. A general method for data representation, data storage and data access of HLA interface was brought forward in this interface. And the dynamic subscription and reflection of object class attributes were also realized in this interface. Furthermore, the number of static linking between the simulation application and Run-Time Infrastructure （RTI） in the HLA interface source RTI was realized by utilizing the Federation Object Model （FOM） document parsing for dynamic acquisition of FOM information. Finally, an application example of the HLA interface design of the Virtual Environment for Virtual Prototyping （VE4VP） was proposed to illuminate the validity of this HLA interface.
