【摘要】 在人们的日常生产和生活当中，融合了多种先进技术的视频监控产品发挥着重要作用，它给人们的工作和生活带来了极大的便利。本文针对某些特殊的应用环境，提出利用基于WinCE.net的嵌入式技术和现有GPRS网络资源实现远程视频监控的方案，完成嵌入式远程无线视频监控系统的开发。该系统由监控中心和监控终端两部分组成，其中监控中心是一台连入Internet网络的PC，负责协调控制系统中各个模块的动作，管理监控内容；监控终端由嵌入式平台、视频模块、CCD传感器和GPRS Modem构成，负责图像采集、处理和传输以及现场重要数据的获取和传输。在简单介绍与系统相关的GPRS技术、基于WinCE.net的嵌入式软件技术及重要硬件原理之后，本文着重阐述基于WinCE.net和GPRS网络的嵌入式远程无线视频监控系统的设计。系统软件主要包括监控终端软件、监控过程通信软件和监控中心管理软件三部分，其中监控终端软件和部分监控过程通信软件都在嵌入式操作系统WinCE.net上开发。监控终端软件负责视频图像采集和处理以及现场重要数据的获取，监控过程通信软件负责数据在GPRS网络和Internet网络上的传输，监控中心管理软件负责管理整个系统并显示监控图像和监控现场重要数据。本文最后对研究内容和系统特点进行了总结，并指出进一步研究的方向。更多还原

【Abstract】 The video monitoring productions, developed by a combination of many techniques, are important to our daily life and work, and make our life and work much more convenient.The Wireless Embedded Remote Video Monitoring System is developed under some special circumstance, with embedded technique based on WinCE.net and the existing GPRS network resource facilitated. The system could be divided into two parts, monitoring center and remote monitoring console. The monitoring center, which is a PC connected to the Internet, takes charge of harmonizing every module. The remote monitoring console, which is composed of an embedded platform, a video module, a CCD sensor and a GPRS Modem, takes charge of image gathering, processing and transmission, as well as acquiring important data on the field and transmission.After briefly introducing the GPRS technique and important theories about the hardware, this paper emphasizes on the design of the Wireless Embedded Remote Video Monitoring System. The system software has three parts, remote monitoring console, communication and management center software. The remote monitoring console software and part of the communication software are developed on the WinCE.net. The remote monitoring console software is responsible for image gathering and processing, as well as acquiring important data on the field. The process of data transferring on the GPRS network and Internet is completed by the communication software. The management center software is used to manage the whole system and display the monitoring images and important data on the spot. Finally, the paper summarizes the main research contents and the features of the system, and then indicates the work to be done in the future.更多还原
