基于GPRS影像监控终端的研究与实现

Research on Implementation of Image Monitoring Terminal Based on GPRS

提出一种基于GPRS技术的影像监控系统,可实现GSM、CDMA和Internet网络的无线远程监控和报警防盗.该系统使用Freescalei.MXLARM9处理器作为系统硬件平台,软件核心架构采用嵌入式Linux操作系统,具有实时性和多线程性,可同时对多个任务进行处理.并同时研究了系统基于ARM的嵌入式技术,遵照WAP2.0技术标准完成终端短信、彩信及Internet网络数据的通信,可实现广泛用于家庭、商铺和企业等场所的安防监控终端.

An image monitoring system is introduced based on GPRS, which is capable of implementing several functions such as GSM, CDMA wireless network, Internet Remote Monitor ＆ Control and emergency alarm. The presented system adopts Freescale i.MXL ARM9 processor as the key hardware platforms, and the major software framework is constructed on the embedded Linux operating system. Such system configuration is able to handle multiple tasks in a real-time and multi-threaded fashion. Also investigated in this report are the ARM-based embedding technology, communications of SMS, MMS and Internet data based on the WAP2.0. The research results can be widely applied to security monitoring terminal for the use of family, department stores and business sectors.
