基于3G网络的无线视频监控终端设计

摘要

This terminal is a digital video surveillance system. It includes video or data acquisition, video compression, 3G wireless video transmission, etc. The control terminal is based on TVP5150 and changes the video signals with camera capture analog into digital signal to input to the DSP. By embedding H. 264- into DSP, it compresses the video stream with terminal receives. And it can meet the needs of high precision real-time video surveillance. This terminal integrates 3G and Internet edge, no matter where and when, the customer can quickly access system, remote monitoring and management. The terminal can be started by SMS mode, command machine control, terminal server, timing and alarm triggers. And it can also collect real-time data.%本终端是集视频或数据采集、视频压缩、3G无线视频传输等功能为一体的数字视频监控终端，终端采用TvP=5150视频解码芯片，将摄像机采集的模拟视频信号转换成数字信号输入到DSP中。通过在DSP中植入的H．264算法来压缩终端接收到的视频流，这能够满足高精度实时视频监控的需求。本终端整合了3G网络和Inter—net网络的优势，无论客户身在何处、在何时间，都可以迅速接入系统，随时随地进行远程监控管理。本终端可以通过短信、命令台控制、终端服务器、定时以及报警触发方式启动，同时可以实时采集现场数据。
