【摘要】 随着图像压缩技术、网络传输技术和电子技术的飞速发展，嵌入式数字图像监控系统已经成为当今监控领域的一个新的开发热点。在特定的工业环境中，由于地理环境偏远等问题，必须采用无线远程的方法进行监控，本系统采用32位ARM处理器与DSP视频压缩模块相结合，并考虑到实际的GPRS与视频传输的速度匹配问题，采用JPEG编码方式，成功的解决了这个技术问题。本文论述了基于GPRS的嵌入式图像监控系统的原理和实现。该系统主要由监控中心和监控终端组成，监控中心和监控终端通过Internet和GPRS网络联系起来，实现通信。监控中心在PC机上建立具有图形界面的监控程序，实现图像监控功能。监控终端采用ADSP-BF531为压缩编码芯片，和外围芯片接口后构成嵌入式计算机硬件平台，为了便于开发和支持网络功能，系统选用嵌入式操作系统wince4.2，组成通用的嵌入式计算机平台，监控终端通过GPRS模块接入移动网络，再通过移动的网关接入Internet。更多还原

【Abstract】 With the rapid evolution of image compression, network transmission and electron technique, embedded imgae monitering system has become a new developing hotspot. Also In some specific industrial environment, by reason of the location or other situations, the wireless remote surveillance is required. This system combines the 32-Bit ARM processor and DSP video compressing module, considering the practical GPRS and video transfer speed, the system uses the JPEG coding, successfully resolved this technical problem. In the dissertation, the principle and implementation of embedded picture monitering system based on GPRS are discussed.The system consists of the monitoring center and the monitoring terminal, and they are connected through the Internet and GPRS network. The monitoring center sets up the control procedure with picture interface on the PC and has the fucnction of monitoring of image.The monitoring teminal is embedded system that consists of ADSP-BF531 and other interface. The embedded system adopts embedded Wince4.2 as the operation system so that the development of software is more converninet. Amd it is connected to the Internet through a GPRS modem.更多还原
