基于HLA的语音通信模拟系统

HLA-based Voice Communication Simulation System

依据高层体系结构标准,通过分析语音通信模拟系统的体系结构,定义联邦成员的仿真对象模型,调用运行时间框架的API实现联邦成员的交互,根据语音通信实时仿真的特点,从应用层的角度提高语音通信模拟系统实时性,运用声明管理和数据分发管理进行数据过滤,设置全局时钟进行联邦成员间地时间同步。实验结果表明,采用的方法能够满足语音通信模拟系统的开发需求。

According to the High Level Architecture（HLA） standard, the architecture of voice communication simulation system is analyzed and the model of federation object is defined, which realizes the interaction of federates by the API of Run-Time Ingrastructure（RTI）. In addition, aiming at the characteristic of real-time simulation, the real-time performance of voice communication simulation system is improved. Declaration management and data distribution management are used for data filter and the method that setting a global clock is used for time synchronization in federates. Experimental results show these ways can meet the development requirements of voice communication simulation system.
