基于GPRS的视频图像传输系统设计与实现

摘要

System need to install digital video equipment on measuring points,and then establish TCP connections through GPRS network to transfer data and instructions. Live video processing module communicates with GSM base station through GPRS Modem,GPRS packet data packet will be sent from the GSM base station to the SGSN node,and then sent to GGSN gateway node by the SGSN. On GGSN Node data packets will be converted into the format that can be transmitted on internet and finally sent to the remote video server. System can transmit real-time pictures and video files to the remote monitoring center via wireless networks,and monitor the measuring points real-time and dynamically. It has properties of strong flexibility and scalability.%设计了可将被监测点实时采集的图片、视频文件通过无线网络传输到远程监控中心,可实时动态地报告被监测点的情况的传输系统,该系统在视频测点安装数字摄像设备,通过GPRS网络建立TCP连接传输数据和指令,现场视频处理模块通过GPRS Modem与GSM基站通信,GPRS分组数据包从GSM基站发送到SGSN节点,再由SGSN送到GGSN网关节点,GGSN把收到的数据包进行处理,转换为可在Internet中传送的格式,最终送给远程视频服务器端.
