基于动态航路的EFIS仿真系统设计

2Design of EFIS Stimulation System Based on Dynamic Air Route Map

针对现阶段电子飞行仪表系统(EFIS)仿真软件不能仿真实时动态导航图的问题,设计了动态航路图模块,开发了具备仿真实时导航图能力的EFIS仿真系统。用FLSIM生成飞行参数,包括飞机位置参数、姿态参数和瞬时运动参数,将这些参数进行必要的运算以驱动由VAPS设计的航路图使其产生位移、旋转等变化,由这些变化来表征飞机位移、转向等运动。围绕航路图设计了其它图形化模块,并设定了这些模块的组合逻辑。最后进行仿真验证,结果表明,动态航路EFIS仿真系统能准确仿真实时导航图。系统软硬件结构简单,具有低成本的优势,在教学、飞行训练等领域有着实际应用前景。

Targeted to the issue that Electronic Flight Instruments System （EFIS） stimulation software cannot stimulate real-time navigation map, this paper designed the model of dynamic air route map and developed an EFIS stimulation system based on it. Flight parameters generated by FLSIM, include locations, attitudes and shifts. They drive the air route map, designed by VAPS, thus the map rotates and moves. Those kinds of changes can represent exactly the changes of plane. Around air route map, this paper also designed other graphic models and defined combi- nation logic of the models. Finally, the stimulation test shows that EFIS stimulation system based on dynamic air route map can stimulate real-time navigation map. This system has advantages of low cost and simple structure so that it is practical at education and pilots training.
