摘要
对锅炉控制系统远程实验中的重要环节——视频传输进行了研究探讨,运用Winsock技术,实现了图像的存取、压缩、编码。为了加快图像的传输速度,本文采用哈夫曼编码算法对图像进行压缩和解压处理,提出了可以加快图像传输的方法,使得实验现场的画面动态更新较快。
The key problem about the boil-controlled remote experiment -visual transferring,is studied in this paper with Winsock technology to realize the acess,compression,encoding of the images In order to enforce the transferring speed,the Huffman algorithm is adopted to deal with the compression and decompression of the image,presenting the way of speeding the video transferring ,which makes the video refresh more quickly.Debugging in Intranet proves that the system can realize video transferring much better.
