Linux嵌入式网络仪器的远程图像通信系统实现

为了在嵌入式中获得数字图像的远程通信和Internet传输,实现了基于uClinux嵌入式操作系统的图像信息采集网络仪器和通过拨号方式的嵌入式远程图像通信系统。网络仪器由MCF5272为硬件核心,以uClinux为操作系统。采用拨号方式实现远程接入Internet。图像经过解码和编码后,以文件方式保存和传输。介绍了图像采集网络仪器的构成、远程图像通信系统的组成、接入Internet的uCl; nux拨号方式、接收图像信息的Internet远程服务器的配置、嵌入式中图像文件自动传输与接收设计。并通过实验检验了网络仪器和远程通信的实现方案。结果表明,在Linux嵌入式网络仪器中采用远程拨号方式可以实现图像的因特网通信。

Realization of remote image communication system in embedded network instrument based on Linux

In order to complete remote image communication through Internet,the network instrument based on uClinux operation system for gathering image and remote image communication by dialing to Internet in embedded system was completed. The network instrument was made of MCF5272 with the uClinux operation system, and linking to Internet by dialing modem. The image was stored and transmitted by the manner of file after decode and encode. The structure of network instrument for collection image, the system of remote image communication,the manner for dialing to Internet, the configuration of remote image server in Internet, the design of automatic transmitting for image files in embedded and receiver were introduced in the paper. The experiment of remote image communication with the embedded network instrument was done. The result indicates that the remote image communication in embedded network instrument based Linux is successful.
