摘　　要：在飞行试验中,机载PCM数据流实时监控一般采用以工控机和PCM解调卡为构架的方案,所研制设备体积大,重量大,不适合小型飞行器使用。采用嵌入式FPGA/DSP技术设计了一种机载PCM数据流实时监控显示系统,详细阐述了解调电路、控制程序和数据显示的设计方法。该系统实现了PCM数据流的机载实时解调、数据显示功能,满足小型飞行器机载PCM数据流实时监控的需求。In flight test, it is popular that PCM display and control in real-time with industrial computer and PCM decoder. But this product developed is not suitable on small-sized aircraft because of volume and weight. This method was not adopted, but another outlined with embedded technology of FPGA and DSP. It has been not only described that decoding of PCM streaming data and the way of data displaying, but also realized the function of PCM decoding and display in real-time. It has been resolved the problem of not suitable mode of PCM displaying on small-sized aircraft.
