基于GPS/GPRS车载图像监控系统的设计 摘要 随着嵌入式应用技术和无线网络技术的快速发展，结合了GPS定位技术和GPRS无线通信技术的嵌入式GPS车载监控系统应运而生。论文将USB视频采集技术引入到车载终端监控系统中，提出了一种车载监控和图像传输系统的具体实现方案。 论文首先对车载监控相关的GPS定位技术、GPRS无线网络技术及USB接口技术做了详细介绍。然后是对车载监控终端硬件方案的设计与实现,给出了具体的实现框图。最后对系统中所用到的主控制模块S3C2410X处理器、GPS模块及GPRS通讯模块等作了详细的介绍。为减少GPRS网络传输的数据量，在图像采集模块中采用了JPEG软件压缩编码技术，对静态图像进行压缩编码，较大地节省了网络资源，提高了图片的传输速度。论文的最后总结了所完成的工作，给出了设计的不足之处和有待完善的地方。 基于GPS/GPRS的车载图像监控终端最终可以实现GPS定位数据和图像数据的采集与上传功能。利用这些信息，监控中心可实时跟踪车辆并及时获取车内信息，该方案充分利用了S3C2410X处理器资源，方便且实用地实现了低成本的车辆监控功能。 关键词： GPS定位技术，GPRS通信技术，车载监控终端，图像采集 Carries the image monitor terminal based on The GPS/GPRS vehicle the design Author: Li Baohai Tutor: Zhao Yanjie ABSTRACT With the rapid development of the embedded-applications and wireless network technology, the embedded vehicle monitoring system which combines the GPS location technology and GPRS wireless communication technology comes into being . In order to meet the requirement, the paper introduces USB video capture technology into embedded vehicle monitoring terminal and puts forward a new solution. Firstly, the paper describes the GPS technology, GPRS wireless network technology and USB interface technology in detail .Secondly, the paper explains how to carry out the hardware design. Give a specific realization of block diagram. The last introduce the main control module S3C2410X processor, GPS module and GPRS communication module used in the system. In order to reduce the quantity of data transmitted by the GPRS network, JPEG compression technology was used to compress static image in the image acquisition module, which could economize the network resources and speed up the image transmission. Finally, the paper summaries all the works and gives the methods for further improvement. The embedded vehicle image monitoring terminal which uses GPS/GPRS technology could collect the GPS and picture information about the automobile and send it to the monitoring center .Making use of the information, monitoring center strengthens i
