基于3G和WiFi的无线视频监控系统的设计

Design of Wireless Video Monitoring System Based on 3G and WiFi

为了实现对远程环境的无线智能监控和提高用户控制体验,研究了3G和WLAN无线网络的特点,提出一种以ARM和Linux为平台,融合3G和WiFi无线网络,设计一款无线视频监控系统。利用摄像头进行视频图像的采集,使用H.264进行图像的编码压缩和RTP协议进行图像传输,借助3G网络实现远程控制传输,同时利用WiFi实现局域网络接入的补充。实验结果表明,该设计可以实现PC、平板PC、手机同时多路连接监控,3G、WiFi网络可任意切换,达到预期效果。

In order to achieve the wireless intelligent monitoring of the remote environment and improve the user＇ s control experi- ence, the characteristics of 3G and WLAN wireless network are studied, an idea of developing a wireless monitoring system is pro- posed, using ARM and Linux as a platform, integrating contents of 3G and WiFi wireless network. The camera is used tot video im- age collection, H. 264 is used for image compression and RTP protocol is used for image transmission, to realize remote control transmission of 3G network, WiFi is used to realize the supplement of local area network access. Experimental results show that PC, tablet, mobile phone can connect the system at the same time, 3G and WiFi network can switch to each other, the outcome a- chieves the desired effect.
