图像监控系统是一门集计算机技术、通信技术和数字图像处理技术于一体的综合系统。它以其直观、方便、信息内容丰富等特性而被广泛应用于工业生产、交通、电信、电力、银行、智能办公大楼等场所。网络技术、嵌入式技术和图像处理技术的发展使得数字化图像数据的网络实时传输和控制成为可能。嵌入式图像监控系统就是一种以嵌入式技术、图像压缩编码技术、网络传输控制技术为核心的新型监控系统,它在稳定性、实时性、处理速度、功能、价格、扩展性等方面和传统的监控系统相比有着突出的优势,同时也代表着目前图像监控系统研究和发展的方向。
本文设计了一种基于嵌入式的远程图像监控系统,系统以ARM7作为核心处理器,并采用μClinux操作系统,实现前端采集的图像信息经GPRS无线信道进行远程传输。
本文完成的工作包括嵌入式远程图像传输系统硬件平台搭建与软件开发。硬件方面,完成了以ARM7微处理器(Samsung公司的S3C44BOX)为核心的系统硬件平台搭建。该系统硬件资源包括S3C44BOX,Flash,SDRAM,UART,以太网控制器以及LCD接口等;软件方面,针对硬件平台完成Bootloader移植和μClinux移植,并完成嵌入式监控终端和上位机应用程序的设计。在本系统中把上位机做为服务器,嵌入式监控终端做为客户端,通过GPRS网络客户端应用程序和服务器应用程序在Internet上建立联接,从而可以相互访问。
本文首先综述了课题研究的目的意义以及国内外研究现状。其次设计了以ARM7为核心处理器并采用嵌入式μClinux操作系统的远程图像监控系统整体方案。从Bootloader概念出发,对U-Boot在系统硬件平台上的移植做了详细的分析,并研究了其在移植过程中经常出现的问题,提出了解决方法。分析了μClinux系统结构及驱动程序原理,并在系统硬件平台上实现μClinux移植。最后研究设计了系统整体软件设计,包括上位机软件设计和嵌入式终端的软件设计,并给出了实验结果。
Monitoring system on image is an integrated system which refers to computer technology,communication technology and digital image processing technology. Because of its direct-viewing,convenience and abundant information,it has an abroad application in the area of industry,traffic,telecom,electric power,bank, intelligence building etc.With the development of network technology,embedded technology and image technology,it has been possible to transport and control digital image data on networking real-time.Embedded monitoring system is a new digital monitoring system based on embedded system technology,image technology and real-time network transport technology.It has many advantages compared to the old monitoring system,such as stability,real-time performance,functions and price etc.It is also the direction of research and development in monitoring system.
The paper designs a kind of remote monitoring system on image based on embedded system.The system is designed based on ARM7 as its core processor andμClinux as its operating system.The system accomplishes that the front-end image information transport to the server by GPRS wireless channel.
The completed works in the paper include the hardware platform design and the software design of the remote monitoring system.With the regards to the hardware design,it completes the system hardware platform design based on ARM7 microprocessor as core MCU.The hardware platform includes S3C44B0X,Flash, SDRAM,UART,Ethernet controller and LCD interface etc.As far as the software design,it transplants Bootloader andμClinux kernel to the system hardware platform and completes embedded chip and PC monitoring software design.In the system the PC monitoring as server and the embedded chip as client can communicate each other through GPRS network.
In the paper,it introduces the purpose and significance of the design and the status of the domestic and foreign research at first.After that,it designs the embedded remote monitoring system on image based on ARM7 andμClinux.Then it analyses the transplantation of U-Boot to the system hardware platform,and details the problems of the transplantation and the methods of resolution the problems.It analyses the structure ofμClinux kernel and the Linux device driver,and transplantsμClinux to the system hardware platform.At last,It details the software design of the system include the PC monitoring software design and the embedded chip software design,and describes the experimental results.
