飞行仿真系统虚拟仪表关键技术

Key Technology of Virtual Instrument in Flight Simulation System

为满足模拟飞行训练的要求,构建真实性强且支持多平台运行的虚拟仪表,对虚拟仪表系统的关键技术进行研讨。基于Visual Studio 2003与GL Studio平台,在现有传统仪表的基础上,分别对虚拟仪表的按钮控件和计时器系统进行设计,通过设立缓存对象使主控送数与人工送数功能同时运行,给出参数处理逻辑算法,根据需求设置系统的修改功能,并通过构建数字仪表进行算法验证。经验证数字仪表运行状况良好,上述功能基本得到实现,运行结果证明了上述关键技术的有效性。

In order to meet the needs of simulated flight training and build virtual instrument with strong authenticity and support for multi-platform operation,the key technologies of virtual instrument system are discussed.Based on Visual Studio 2003 and GL Studio platform,on the basis of existing traditional instrument,and parameters of the button control system part,provide some addition logic algorithm for implementing the following functions.By setting the cache object makes the data transmission of master and manual operation and can run at the same time,improve the instrument human-computer interaction ability.A timer system suitable for virtual instrument is designed.On the basis of the timer,a button control response system is set up to recognize the button behavior freely and improve the flexibility of the using of buttons.Finally,a digital instrument is constructed based on the algorithm operates well,verified the algorithm and the above functions are basically realized,and the above key technologies are proved to be effective by operation results.
