分析了当前综合航电显控系统仿真中存在的问题,讨论了此系统的功能、组成及仿真设计方法。结合模拟器研制需求,提出了一种元模型特性的可重构建模方法。利用特征提取法的元模型理论,将构成系统的各个元素及其相互关系合理分类和特征抽象与描述,构建显控系统的元模型。利用GL Studio创建显控系统的图元、字符和人机交互界面;采用面向对象技术对元模型逻辑、画面构建、数据处理进行代码可复用类设计。通过仿真应用验证,结果表明该方法避免了系统仿真中存在的问题,可显著提高显控系统的开发效率,支持多种机型模拟器显控系统的开发。

Analysed of the current integrated avionics display and control system simulation problems, discussed the system's function, composition and the simulation design method detailedly. Proposed a reconfigurable modeling method of meta-model features according to the requirements of the simulator develop. Make full used of the feature extraction method meta-model theory, the various elements that make up the system and their relationship was classified and feature abstract and description reasonably, built the meta-model of display and control system. Created the display and control system's graphic elements, characters and Human-computer interactive interface by GL Studio. Using object-oriented techniques to make reusable class design of meta-model logic, menu build and data processing. Verified through simulation applications, the results showed that the method avoids the problems of System Simulation, could significantly improve the development efficiency of the display and control system, supported the development of display and control systems in multiple type of aircraft simulator.
