摘要
分析了PCM与PPM两种编码方式,比较了其应用于无人机飞行控制领域的优劣。针对FUTABA6通道无人机手遥控制器,设计实现了基于TMS320C2812 DSP芯片的PCM波解码器,实现PCM波的捕获和解码运算,通过RS-232串口协议与上位计算机进行通信。上位机利用MATLAB进行数据的处理。实验表明该解码器可以准确地将无人机遥控器发出的脉冲控制信号数字化解码,显示于上位计算机。
The coding mode of PCM and PPM were introduced, and the application on the UAV control system was compared. Aiming at the PCM signal sent by 6 channels remote controller, A PCM decoder was designed for the UAV remote controller based on TMS320C2812 DSP. By this decoder, the PCM wave was decoded and captured. Through the RS-232 protocol, the DSP communicated with the PC. MATLAB was used on the PC to process data. Experiments show that the decoder can accurately decode UAV remote control pulse signals, and the result was showed on the computer.
