基于MDA的虚拟仪表建模与仿真平台设计
|
摘要
目前,模拟器在现代教学与训练中得到了越来越广泛的应用,虚拟仪表成为模拟器研制中不可或缺的重要模拟组件,呈现高度化集成、综合化显示的发展趋势,如何快速地构建虚拟仪表仿真应用成为项目研制中的突出问题.本文以虚拟仪表的仿真为中心,基于MDA的思想,构建了虚拟仪表建模与仿真平台,并对平台中的基础性图元、设备图元、语义、类代码生成等关键性模型组件的设计实现方法进行了探讨.实际应用表明,利用该平台可快速实现虚拟仪表软件的开发,具有效率高、柔性强的优点.
At present,simulator has been used in modern teaching and training widely. Virtual instrument is an important assembly in the development of simulator,appears the trend of high integration and synthetic display. It is an outstanding problem how to develop the virtual instrument application rapidly in the project development. The paper develops the modeling and simulation platform of virtual instrument based on MDA around the virtual instrument simulation. Key modeling assembly has been discussed in detail,including basic graphic elements,device graphic elements,semantics and class code generation as so on. The platform has been applied in the actual project,can develop the application of virtual instrument rapidly,and has advantage of high efficiency and strong flexibility.
