本文介绍了一种自主研发的远程图像监控系统,该系统利用人工控制和自动报警两种方法,通过CDMA无线网络和INTER网将远程抓拍图像传送到监控中心,达到图像监控目的。详细阐述了如何使用SL811作为接口芯片的USB主机的设计方法以及利用单片机通过CDMA模块与INTER网上的计算机进行通信,并将图象数据发送到网络监控中心。特别介绍了PPP、IP、UDP三种网络协议的格式和打包方法,列出了详细的工作流程图,最后通过大量实验结果给出了兼具实时性和高效率的最优化方案。 This paper introduces a self-developed remote image monitoring system. The system uses manual control and automatic alarm two methods, through the CDMA wireless network and INTER network remote capture images sent to the monitoring center, to achieve the purpose of image monitoring. Described in detail how to use the SL811 as a USB host interface chip design method and the use of single-chip CDMA module with the INTER online computer to communicate and send image data to the network monitoring center. In particular, we introduce the formats and packing methods of PPP, IP and UDP, and present the detailed working flow chart. Finally, we give the optimization scheme with both real-time and high efficiency through a large number of experimental results.
