大型运输机综合训练器虚拟仪表系统的研究

Research of Virtual Instrument System for Large-scale Aerotransport Integrated Training Simulator

随着计算机技术的快速发展,使虚拟仿真模拟器在军事训练中得到了广泛的应用。目前模拟器仪表系统主要是实表系统,存在驱动复杂、价格昂贵等缺点。结合大型运输机综合训练器的研制,介绍了采用虚拟仪表替代真实仪表的训练器体系结构,给出了利用GL Studio3.0来开发虚拟仪表的过程、数学模型及人机交互方法。以高度表、地平仪等典型虚拟仪表的开发为例,介绍了虚拟仪表中指针、数字轮以及非线性刻度的显示方法,并给出了一些相应的C++代码,为训练模拟器的仪表仿真提出了新的解决方案。

Along with the rapid development of computer technology, virtual simulators are used widely for military training. At present, the instrument system of simulator is mostly real instrument system that has some disadvantages of complex driving and high price. According to the development of large - scale aerotransport integrated train- ing simulator in which the virtual instrument system is used, the simulator architecture,in which the real instrument is replaced by virtual instrument is introduced in the paper. The development process of virtual instrument by means of GL Studio3.0 software, mathematical models and man - machine interactive methods are presented. Displaying methods of needle, digital wheel and nonlinear graduation are introduced through the example of developing some classic instruments such as altitude indicator, horizon sensor etc , and some corresponding C ＋ ＋ codes are given. A new method is provided to implement the instrument simulation of training simulator.
