为增强飞行员对控制显示组件(CDU)的直观感受,提高CDU仿真的逼真度,基于嵌入式PC104 CPU和8255可编程设备接口卡,设计仿真键盘硬件电路和键盘码扫描程序,实现对CDU键盘的高逼真硬件仿真。利用面向对象仿真技术,创建出CDU仿真页面,有效解决了页面系统繁重的生成与管理问题。仿真实验结果表明,该方法能够逼真地实现对飞行计算航路数据和性能参数的输入与显示。
In order to enhance the intuition of pilots’ control display unit (CDU) and improve the fidelity of CDU simulation, an emulation keyboard hardware circuit and keyboard code scanner are designed based on embedded PC104 CPU and 8255 programmable device interface card, High realistic hardware simulation. The use of object-oriented simulation technology to create a CDU simulation page, effectively solve the page system heavy generation and management issues. The simulation results show that this method can realistically realize the input and display of flight path data and performance parameters.
