基于VxWorks的人机界面图形开发系统设计

摘要

针对当前嵌入式实时系统VxWorks图形界面开发支持较弱的缺点,结合海军多功能标准台项目,分析了VxWorks实时操作系统下国内外主流图形开发系统的设计原理,采用了基于控件技术的层次化设计和面向对象的设计方法,实现了一种在VxWorks实时操作系统下具有自主知识产权的人机界面图形开发系统JARI EGK.通过多个项目中的应用验证,JARI EGK在功能和性能方面能够满足基于VxWorks实时系统的窗口图形界面开发要求.%According to the disadvantages of graphics interface design under the real-time embedded operation systems VxWorks, and combining with the Multifunction Console projects, this paper analyzes the design principle of graphical user interface library at home and abroad, and adopts the architecture of hierarchical design and object-oriented programming. One kind of graphical user interface library(JARI_EGK) which possesses independent intellectual property rights is realized and used successfully. Through applied to many projects, JARI_EGK is proved to satisfy the requirement of developing graphical interfaces based on Vx Works real-time system.
