摘　　要：机载显示系统直接关系到先进航电系统的性能和成本,针对机载显示系统的特点、性能要求,分析了目前机载显示系统存在的复用率低、不易于移植、继承性差、无法重构、成本高等缺陷;提出了基于抽象工厂模式的图形生成设计新思想,对机载显示系统图形库进行分类、分级抽象,建立图形处理模型、图形绘制模型和显示模型三级架构,统一了字符、图形、窗口的模型处理方法;基于OpenGL实现了图形模型开发库和机载显示系统图形生成架构,以该方法实现了某型飞机显示系统的开发,实验证明,该方法实现了显示系统通用开发技术和软件重构技术。The airborne display systems are directly related to the performance and cost of advanced avionics systems. According to the characteristics and performance requirements of the airborne display system, the shortcomings of current airborne display system are analyzed, such as low multiplexing rate, difficult to transplant, poor inheritance, unreconstructible, and high cost. A new idea of graph generation design based on abstract factory pattern is proposed. The graphics library of airborne display system is classified and described abstractly in different levels, and a three-level architecture of graphics: processing model, graphics drawing model and display model, is established. Unified model processing methods for characters, graphics, and windows. Based on OpenGL, the graphics model development library and the airborne display system graphics generation architecture are implemented, this method realizes the development of a certain aircraft flight display system. Experiments show that the method implements the general development technology and software reconstruction technology of the display system.
