摘要
介绍一种基于Linux的嵌入式操作系统和CDMA1X无线数据业务的图像监控系统方案。系统以Linux操作系统为软件平台,以ARM9微处理器AT91RM9200为硬件平台,采用MPEG-4的专用编码芯片GO7007SB对采集到的视频信号进行压缩编码,然后生成MPEG-4视频流。AT91RM9200将视频流进行处理、缓存后通过串口发送到CDMA 1X无线模块,通过CDMA1X业务将图像数据发送到远端服务器。远端服务器具有固定的实IP地址。远端服务器通过SOCK-ET接收图像数据并进行解码显示,还可以通过发送控制信号实现对下位机的控制。
This paper introduced an embedded wireless image monitory system based on Linux. This system based on embedded Linux system and ARM9 microprocessor AT91RM9200, dedicated to the acquisition of digital video compression using the MPEG-4 coding chip GO7007SB, generated MPEG- 4 streaming. AT91RM9200 processed the MPEG- 4 streaming and sent it to the CDMA 1X wireless module, transferred to the remote servers of Internet through CDMA 1X wireless service. The remote servers have a fixed and real IP address. The remote server received image data through SOCKET and decoded image data to display, controlled the monitor terminal by sending control signal.
