为解决基于文档的综合通信导航识别系统设计中需求传递的歧义性、设计文档信息离散、系统无法进行仿真验证等问题,研究了一种虚拟样机设计方法。首先,针对综合通信导航识别系统多领域的特点设计了一种由需求模型、架构模型和实现模型构成的三层次虚拟样机模型;其次,对当前主要的基于模型的设计方法与流程进行了深入研究,通过对比分析选择了Harmony SE作为综合通信导航识别系统虚拟样机的设计流程;最后,以某综合化通信导航识别系统为例进行了三层次虚拟样机的设计及仿真验证。设计结果表明,该设计方法能有效解决基于文档设计存在的问题,适用于各类综合通信导航识别系统虚拟样机的设计。

A virtual prototype design method is studied to resolve the problems including requirement ambiguity, information scattering, and absence of simulation in document-based integrated communication, navigation and identification system （ICNI） design. Firstly, a three-level virtual prototype composed of requirement model, architecture model and implementation model is designed according to the multi-discipline of ICNI. Then, a cursory description of some of the leading model-based system design methodologies is provided and Harmony SE is selected as the design flow for the ICNI virtual prototype after comparison. Finally, a virtual prototype for a distributed ICNI system is created and verified through simulation. It can be concluded that the virtual prototype design method resolves the problems in document-based design and fits for all kinds of ICNI system design.
