基于VAPS的机载多功能显示器的仿真研究

高度集成机载电子设备信息的多功能显示器的出现改变了以往飞机座舱中仪器仪表繁多的布局,使得飞行员能快速获得飞行信息,更加有效地管理和操纵整个系统。本文介绍了在PC机上通过VAPS和VisualC 来构建仿真系统的界面和显示驱动程序,使用VAPS可有效支持图形显示,简化图形显示控制方面的工作。显示驱动程序是仿真实现的关键,程序被设计成实时多任务多线程结构,飞行数据的实时处理和界面显示控制将以任务方式挂载到任务队列上调度执行。结果表明,该仿真方法具有很强的通用性和可扩展性等优点,能很好地实现多功能显示器的仿真。

Simulation of airborne multi-function display based On VAPS

With the appearance of multi-function display system that highly integrates the digital information from airborne devices, the cockpit layout is changed and the pilot can get flight information more quickly and control the aircraft more efficiently. The authors studied the simulation of multi-function display. VAPS and Visual C are used to construct GUI and display driver of multi-function display system. VAPS can support graphical display and simplify the control of it. The display driver is the key of simulation, in which real-time, multi-task and multi-thread structure is used to simulate the system behavior better. The handling of flight data and GUI control are executed as tasks that should be loaded in task list. It is concluded that this method have good adaptivity and expansibility and can supply good simulation performance.
