机载多功能显示器的半实物仿真实现

Hardware-in-loop simulation of multi-function display

机载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,使得各型机载电子设备能在多功能显示器上进行高度集成的显示和控制,因此多功能显示器是目前各航空训练模拟器中不可缺少的一部分。本文介绍了一种基于半实物仿真实现的机载多功能显示器,它以单片机为输入监听单元,独立完成对周边键的实时响应;以工控机为显控核心,完成各种飞行信息的显示输出。应用结果表明该仿真技术具有实时性好、通用性和可扩展性强等优点,能很好地满足各型航空训练模拟器的应用需求。

Multi-function display,which is the key component of integrated avionics,makes the cockpit clear and control convenient because of integrating almost all airborne devices display and control.Because of these advantages,the simulation of the multi-function display is indispensable to the aviation maintenance training device. This article introduces a hard-in-the-loop simulation of aviation maintenance training device,with a single chip as input monitor and an IPC as core of display to achieve the functions of control and display in real time. The application of this hardware-in-the-loop simulation proves that this method has good performance in aviation maintenance training device simulation.
