【摘要】：随着3G网络技术的逐渐成熟和4G网络的快速发展,以及图像数据处理技术和嵌入式技术的迅速发展,视频监控系统进入了一个更加广阔的第三代数字化网络化视频监控时代。如今,社会上的治安状况日趋复杂,不断出现的公共安全新问题和城市犯罪高发生率等现象都迫切需要加快发展无线视频监控技术,因此,基于无线网络的嵌入式远程视频监控系统已成为视频监控开发领域的主要趋势。本文研究设计了基于3G网络的智能手机视频监控系统。该系统根据功能划分为采集模块、编码模块、传输模块、显示模块,采用的技术主要有H.264视频压缩编码技术、3G移动通信技术、FFmpeg技术,Android应用软件开发技术。本文的视频监控系统需要完成在服务端和客户端的视频播放工作,具体的工作流程：首先搭载了一个开发平台,以ARMll的S3C6410处理器的开发板和电脑上的虚拟机Linux系统共同组成,在此基础上,完成软硬件开发环境的构建,即对嵌入式系统进行交叉编译环境建立和目标板Linux操作系统裁剪移植,通过这个平台完成视频的采集和编码,并且完成服务端的视频解码显示；接着通过3G模块中兴AD3812完成基于TCP/IP协议的无线视频传输工作,最后,搭建Android应用开发平台,在此平台上开发出一款视频流播放器,完成视频的播放显示功能。测试表明本文设计的基于3G无线嵌入式视频监控系统实现了视频监控的基本功能,在功耗、体积、实时性、可移动性和可扩展性等方面有明显优势,具有良好的应用空间。
[Abstract]:With the gradual maturity of 3G network technology and the rapid development of 4G network, as well as the rapid development of image data processing technology and embedded technology, The video surveillance system has entered a broader era of digital and networked video surveillance. Nowadays, the security situation in society is becoming more and more complicated. The emerging problems of public safety and the high incidence of urban crime are all urgent to speed up the development of wireless video surveillance technology. Embedded remote video surveillance system based on wireless network has become the main trend in the field of video surveillance and development. This paper studies and designs a video surveillance system of smart phone based on 3G network. The system is divided into three modules according to its functions: acquisition module, coding module, transmission module and display module. The main technologies adopted include H.264 video compression and coding technology and 3G mobile communication technology FFmpeg technology and Android application software development technology. The specific workflow: first, a development platform is built, which is composed of the development board of ARMll S3C6410 processor and the virtual machine Linux system on the computer. On this basis, the software and hardware development environment is constructed. That is, the embedded system is cross-compiled environment and target board Linux operating system cut and transplanted, through this platform to complete the collection and coding of video, and the server end of the video decoding display; Then the wireless video transmission based on TCP/IP protocol is completed by ZTE AD3812, the 3G module. Finally, the Android application development platform is built, and a video streaming player is developed on this platform to complete the video playback and display function. The test results show that the wireless embedded video surveillance system based on 3G has realized the basic functions of video surveillance, and has obvious advantages in power consumption, volume, real-time, mobility and scalability, and has good application space.
