摘要
随着电力线通信的广泛应用,电力载波视频监控也越来越受到重视。文中提出一种基于电力载波的视频监控系统的软件设计的方法。系统采用ARM+Linux的软硬件平台,将摄像头采集来的视频图像经过压缩芯片压缩后,再通过实时传输协议RTP/RTCP和传输层的UDP协议进行传输,然后在PC机上接收数据并显示出来。整个系统建立在嵌入式Linux平台上,能独立完成视频的采集、压缩和传输功能,可广泛应用于视频监控领域。实验证明该方法是可行的。
With the extensive application of power line communication, the video surveillance on power line carrier has become increasingly attention. Introduces the software design of a video monitoring system based on power line. With the ARM and Linux plantform,the collected video images from cameras are compressed by compression chip. Then the images are transmitted through the real - time transport protocol RTPZRTCP and the tansport layer UDP protocol. At last the data are received and shown on a computer. The whole system is established on an embedded Linux platform with the function of video images collection, compression and transmission. It can be generalized to the application of most video monitoring area. Experiments show that the method is feasible.
