摘　　要：针对工业控制中视频信号的快速数字采集与低速串行通讯之间的冲突，结合实际应用中视频传输的情况，通过硬件设计分配以及合理利用系统时间，经巧妙的软件设计，有效的压缩了视频信号中的冗余数据，解决了二者之间的矛盾．实际运行证明：此方法工作稳定而可靠，具有实用价值．The conflict between the fast signal collection of video signal and low speed of seri- al communication in the industry control is expatiated in this paper. Conflict is overcomed based on the application by the way of hardware designed, time of system utilize fully and software de- signed felicity, redundancy data are compressed efficiency, the resolution of this contrary is proved to be stable, reliable by practical running.
