毕业论文 基于3G的家庭远程视频监控系统的研究与设计 基于3G的家庭远程视频监控系统的研究与设计 摘 要 随着科技的发展和人们安全意识的提高，远程监控系统得到越来越广泛的应用，但是以往的远程监控由于硬件结构、网络结构的复杂性及传输速率的限制，使之在技术上和成本上形成瓶颈，不适合用于家庭远程监控。近年来发展迅速的3G移动通信技术和3G网络建设以及智能监控技术提供了解决这一问题的有效途径。 本文主要介绍基于TMS320DM642和3G无线数据模块的家庭远程视频监控系统的设计与实现。该系统以高性能DSP芯片TMS320DM642为核心，包括视频采集模块、和无线传输模块以及备份模块，可以同时采集三路视频和多路现场设备工作信息，并对实时情形进行运动检测，然后对视频进行MPEG-4编码，由DTM6211无线收发模块通过3G网络发送给远端3G终端手机，实现实时监控。本文还给出了一些视频驱动方法并探究了运动检测的算法问题。还对TMS320DM642与DTM6211之间的通信问题进行了详细阐述。 另外，因为本文的目的是探讨一种家庭监控系统的设计方案，最终目的是为了推向实用端，故在具体设计中始终注意了整个系统的成本问题，力求在系统的设计中就能够为以后的实际应用打下坚实基础。 本文最后对全文做了总结，讨论了一些需要继续深化和改进的地方，并提出了相应的改进办法。 关键词：家庭监控，远程视频监控，3G，运动检测， DSP 3G-based family of Remote Video Surveillance System Research and Design Author：Lei Lu Tutor：Fengwen Wang Abstract With the development of science and technology and peoples safety awareness, remote monitoring surveillance system has been increasingly widely used, but the past is because the hardware structure of remote monitoring as well as more complex network structure, the cost is often caused by a bottleneck, not suitable for RMON family. In recent years the rapid development of 3G networks and intelligent monitoring technology to solve this problem provided the technical support. In this paper, based on the TMS320DM642 and 3G wireless data modules comprehensive monitoring system of the family of the Design and Implementation. Monitoring System Design and Implementation. The system TMS320DM642 chip for high-performance DSP core, including the video capture module, RS485 bus modules, and wireless transmission module and backup module. Can be collected at the same time three-way video and multi-channel information on the work of field devices, and motion detection for real-time situation, and then on the MPEG-4 video encoding, through the wireless transceiver module DTM6211 sent to the remote end 3G mobile phones, real-time monitoring.
