摘要
针对当前各种嵌入式系统开发中存在的图形界面开发较难的现状,介绍了一种新型的具有简便的图形界面开发功能的嵌入式系统——QNX;通过其自带的PhAB开发工具,可以方便地开发出用户所需的良好界面;根据QNX强实时性和高可靠性的特点,结合无人机地面控制台嵌入式系统的开发,论述了QNX下嵌入式系统的开发过程以及图形界面的开发方法,叙述了控制台软件的设计思想,给出了软件图形界面,对用户定制其它的带有图形界面的嵌入式系统具有一定的指导意义;通过实时性测试分析可以看出,系统实时响应时间在1-28ms之间,完全满足实时系统的要求。
Taking into account the difficulties in the development of Graphic User Interface in various embedded systems, this paper in- troduces QNX--a new embedded system with simple development function. It serves to develop satisfactory interfaces catering to the need of customers in an easy way via its self--contained developer kit PhAB. With its characteristics of high real--time and reliability and with the assistance of the development of UAV ground control console embedded system, this thesis elaborates the development process of QNX embedded system and ways for exploring Graphic User Interface. Moreover, it describes the design idea of console software and offers software graphical interface, which is significant to customizing other graphical interface embedded system. With the analysis of realtime test, it's clearly that the system's response time is between 1 to 28ms, which satisfied the system's requirement.
