摘　　要：采用内置微控制器的液晶显示模块及机械触点式金属键盘,设计了一种航测相机的人机交互系统。系统采用DSP和FPGA协同控制的模式,实现了同液晶显示模块及键盘的软、硬件接口设计。详细描述了系统任务要求、软硬件设计思路及在设计过程中着重考虑的问题。针对液晶屏"雪花"现象产生的原因进行了分析并提出了相应的解决方案,介绍了使用自定义字库进行相机工作信息显示的方法。地面试验及飞行试验表明:系统工作可靠,可视性和可操作性强,满足系统使用要求,为人机交互系统的设计提供了可借鉴的方案。Using LCD module embedded microcontroller and mechanically contacted metal keyboard, a kind of man-machine interactive system for aerial mapping camera was designed. Based on the mode of DSP cooperating with FPGA, the interfaces of hardware and software are realized for LCD module and keyboard. The task requirement, the construction thought and the questions considered emphatically are described in detail. The cause that ＇snow＇ phenomena of LCD is analyzed and the resolution is presented. Furthermore, the design of custom character library is introduced. The experiments on ground and in air show that the system is reliable, and its visibility and operability are satisfying. The requirements for system are achieved, and it provides a kind of referenced design concept for other man- machine interactive system.
