摘　　要：针对目前国内全彩LED显示屏管理终端的地域受限和便携性差等缺点,提出了利用机终端的彩信功能控制更新LED彩屏内容的方案。该方案基于ATmega128单片机完成了JPEG的图像解码,并借助GPRS网络实现了对全彩LED显示屏的文字和图像的远程更改以及系统周边设备的无线控制,且能够回传现场图像达到监控的功能。系统具有成本低、便携性高、实用性强等优点,能广泛应用于车载或者户外广告屏等场合。In response to the problem of lacking portability with the management terminal of full color LED display system, this paper puts forward a solution, which updates the content of full color LED display with the multimedia messaging service （MMS）in mobile phone. The solution decoded JPED image on micorprocessor of ATmega128. It realized updating the texts and pictures displayed in the full color LED display remotely and controlling peripheral wirelessly based on GPRS network. In addition, the display terminal can send back the pictures from the work filed to the mobile phone for supervision. For its advantages of low cost, high portability and strong practicality ,it could be widely applied in such areas of information publicity as outdoor advertising,
