基于QNX的嵌入式操控训练系统软件设计

Software design of embedded control training system based on QNX

QNX操作系统具有可靠性高、实时性强的特点和强大的图形界面功能,基于其开发的水下航行器嵌入式操控训练系统,解决了系统的实时性需求,还能方便地开发出友好的人机界面。简要介绍了QNX操作系统的特点和映像文件配置的一般方法,基于PhAB开发了嵌入式操控训练系统的操控界面,根据系统的模块划分对主程序进行了设计,系统程序运行稳定,满足训练要求,对其他嵌入式训练系统软件设计具有一定的借鉴意义。

QNX,an operating system with strong development function of graphic interface,has the characteristics of high real-time performance and reliability. The embedded control training system for underwater vehicle developed on the basis of QNX can meet real-time requirement of the system and can develop friendly man-machine interface conveniently. The characteris-tics of QNX and the general ways to configure mapping files are briefly introduced. The control interface of the embedded control training system based on PhAB was developed. The main program was designed according to the sort of modules. The embedded control training system can fulfill the requirements of training,and runs steadily,which can be used as a reference to the soft-ware design of other embedded training systems.
