基于ARM/GPRS的远程图像监控技术研究
摘要
随着信息技术和数字技术的发展，特别是对Internet和多媒体通信需求的增长，通信技术的发展主要集中在宽带通信网络和无线通信领域。而GPRS技术又将互联网等宽带数据网络与无线通信网络连接在一起，GPRS的应用范围很广，可以用于开发互联网、用于移动性管理以及无线监控等方面。监视系统是现代农业生产、交通运输、环保监测、保安防火、现代国防等关键技术设备之一。目前在图像监视系统领域，有线方式的图像监视系统较为普遍，而在设备分布广泛和数据不易采集的场合，有线图像监视方式受到了固有物理布线的限制而显得无能为力，但无线远程图像监视方式则没有这种限制。随着计算机技术和通信技术的发展，将嵌入式系统技术、无线通信技术和基于TCP／IP的Internet技术结合在一起的无线远程图像监视系统成为可能。基于嵌入式系统的该类监视系统对嵌入式系统的软硬件开发提出了新的挑战，而图像、视频等大信息量的多媒体无线传输要求也给无线通信技术提出了新的挑战。近年来，随着计算技术、通信技术的飞速发展，特别是互联网的迅速普及和3C(计算机、通信、消费电子)合一的加速，微型化和专业化成为发展的趋势，嵌入式产品成为信息产业的主流。同时数字视频技术应用的广泛，要求其更加灵活的适应现场需求。
无线网络的日益普及，除了语音通讯、短信等常规业务，无线网络还能给我们带来什么样的变革?本文将以基于GPRS的远程图像监控系统的开发为例，介绍无线网络给我们带来的多彩生活。本文以远程图像监控系统开发的整体框架为线索，着重阐述了嵌入式系统软件开发、GPRS无线网络通讯及图像采集终端的实现，同时介绍了系统管理终端在PC机上的实现。
课题的主要工作集中在两个方面：一方面是GPRS无线收发设备硬件实现，在这一部分涉及到模块硬件功能设计、无线模块、单片机设备的选型；另一方面是软件，主要是针对TCP／IP协议进行SOCKET编程，以及上位机监控软件的设计，把监控端上位机做成一个服务器，下位机做成客户端，通过GPRS网络使客户端应用程序和服务器应用程序在Internet上建立联接，从而达到互访的目的。
With the development of Information Technology and Digital Technology in recent years, especially with the large requirement of Internet and multimedia communication, the most fascinating technologies are focused on wide and communication network and mobile communication in the field of communication technology .GPRS (General Packet Radio Service) connect wide band(e.g. Internet) with wireless communication network, so GPRS can be widely applied in Internet, remote mobile management and remote control. Monitoring system is one of the key equipments for the agriculture, transportation, environment monitor and national defenses. Nowadays the lineate monitor systems occupy the monitor system market, but the applications are limited by the physical disadvantages in some difficult situations, such as the monitors' points distribute broadly. The wireless monitor systems are the just resolutions. With the fast development of the computer and communication technology, the wireless monitor system combining the embedded system technology, wireless communication technology and Internet technology can be realized.These monitor systems challenge the development of the embedded system technology. The multimedia data transmitting needs improvements of the wireless communication technology. In recent years, with the rapid development of computer technology and communication technology especially the widely available Internet and the 3C(computer, compunicate, consume electric) united as one, being micro and special become new trend and embedded products become the mainstream of information property. At the same time, the wide application of digital video techniques requires more active adaptability in user requirement.
In the development of Wireless Net, what can it bring to us but communication? This paper deals with the exploiter of a wireless image monitoring system based on GPRS, it shows us the wonderful life that wireless net bring to us. System frame is the clue of this paper. This paper puts the emphases on the software development of Embedded System, GPRS net and the implementing of image collecting terminal. System control terminal on PC is also introduced.Finally.
Main completed works in this paper include: realize GPRS transceiver hardware and software. The part work of hardware include: design function of hardware module, select equipment of wireless module and single-chip; The part work of software include: applied SOCKET technology and TCP/IP protocol to realize communication program; the PC monitoring software design. In this system the PC use as a server, and single chip uses as a client. They communicate through GPRS network.
