针对3G嵌入式终端设备拨号后获得的IP地址为私有动态IP地址，无法作为服务端被远程计算机直接访问的问题，运用3G技术的V PN组网架构设计了3G移动监控系统，实现对3G嵌入式监控前端的访问。该系统基于ARM-Linux嵌入式开发平台，移植并优化Mjpg-streamer视频服务器，调用V4L2接口实现视频数据的采集，图像数据经JPEG压缩后传输至w eb服务器，通过3G网卡实现监控系统的数据传输。实验表明，该系统运行稳定、实时性高、使用便捷，可广泛应用于各个领域。

3G embedded terminal equipment obtains a private and dynamic IP address after dial-up accesses to the internet ,which can not be directly accessed as a server by remote computers .Aiming at this problem ,3G monitoring system is designed by using the VPN network architecture of 3G technology ,and the access to 3G embedded monitoring front-end is implemented .The system is based on ARM-Linux embedded development platform , transplants and optimizes Mjpg-streamer video server ,uses V4L2 to collect video data ,the image data is compressed by JPEG and transported to the web server ,then the data transport of motoring system is realized by 3G network card .The results show that the system has stable operation ,high real-time performance and convenient usage ,which can be widely used in various fields .
