【摘要】：以嵌入式技术为基础的网络视频监控系统有着易于应用、使用灵活以及远程监控的特点,使得工程技术人员、调试人员以及相应的管理人员不用亲临现场,只需通过网络就能够得到远程设备的数据,达到控制、校准的目的。所以基于3G技术的嵌入式视频监控在监控领域的应用越来越广泛,成为当前的研究热点。课题研究的远程监控系统是通过嵌入式监控设备采集视频数据,然后使用3G网络上传至PC服务器,监控端通过web浏览器访问PC服务器,接收视频数据,实现了远距离对事物进行监控。如果想达到对远距离事物的探测,就必须进行数据传输,通过数据的识别来达到传输的意图,但是嵌入式技术正好可以实现这一目的。本文以s3c6410为核心硬件平台开发了以3G网络为基础的嵌入式远程视频监控系统,在课题的研究过程中,首先按照系统需求制定总体设计方案,并有针对性对U-Boot进行一定程度的修改和移植,深入研究Linux内核编译及移植技术,制作YAFFS文件系统,在嵌入式Linux系统安装开发USB接口摄像头、3G无线网卡驱动程序,同时对如何利用Linux自身提供的Video 4 Linux 2 API函数实现视频数据采集进行重点讨论。然后介绍了在Linux下实现基于RTP协议的Socket编程方法,实现网络实时发送视频数据的目的。在网络视频监控系统的PC主机端,搭建了基于RTP协议的Apache服务器,实现了视频数据的存储。课题从视频监控系统现有业务流程出发,按照软件工程思想叙述了项目需求、设计、开发、测试、实施的整个过程,详细论述了视频监控模块、USB设备驱动模块、视频数据处理模块等设计与实现过程,最后进行了详细的系统测试。本系统使用模块化的设计方法,使得设计具有良好的扩展性以及易用性,对于系统的升级更方便。同时采用基于3G技术的嵌入式方法系统成本较低,更适合推广应用。
[Abstract]:The network video surveillance system based on embedded technology has the characteristics of easy application, flexible use and remote monitoring, so that engineers and technicians, debugging personnel and corresponding management personnel do not have to come to the scene in person. The data of remote equipment can be obtained only through the network to achieve the purpose of control and calibration. Therefore, embedded video surveillance based on 3G technology is more and more widely used in the field of surveillance, and has become a hot research topic. The remote monitoring system is to collect video data through embedded monitoring equipment, then upload it to PC server using 3G network. The monitoring end visits PC server through web browser and receives video data. The remote monitoring of things is realized. If we want to detect remote objects, we must carry out data transmission and achieve the intention of transmission through data recognition, but embedded technology can achieve this goal. In this paper, the embedded remote video surveillance system based on 3G network is developed with s3c6410 as the core hardware platform. In the course of the research, the overall design scheme is designed according to the system requirements. The U-Boot is modified and transplanted to a certain extent, the technology of compiling and transplanting Linux kernel is deeply studied, the YAFFS file system is made, the USB interface camera is installed and developed in embedded Linux system, and the 3G wireless card driver is developed. At the same time, how to realize video data acquisition by using video 4 Linux 2 API function provided by Linux itself is discussed emphatically. Then the socket programming method based on RTP protocol under Linux is introduced to realize the purpose of sending video data in real time. The Apache server based on RTP protocol is built on the PC host of the network video surveillance system, and the storage of video data is realized. Starting from the current business process of video surveillance system, the whole process of project requirement, design, development, test and implementation is described according to the software engineering idea. The video monitoring module and USB device driver module are discussed in detail. Video data processing module and other design and implementation process, and finally carried out a detailed system test. The system uses modular design method to make the design has good expansibility and ease of use, and it is more convenient to upgrade the system. At the same time, the cost of embedded system based on 3G technology is lower, so it is more suitable for popularization and application.
