摘要
随着Internet和嵌入式系统的广泛应用,计算机技术、网络技术、控制技术和现场总线技术得到迅速发展,促使测控网络向数据共享更加方便、信息传递更加快捷和交互性更强的方向发展,基于嵌入式Internet技术的远程网络测控应运而生,它将推动控制技术向网络化、开发性和分布性的方向进一步发展。
     现代的测控网络以现场总线技术为核心。现场总线从工业现场设备底层向上发展,计算机网络从互连网Internet顶层向下渗透,直至和底层的现场设备可以通信,就形成了基于嵌入式Internet技术的现代测控网络。
     本文首先分析了现场总线系统(FCS)与传统集散控制系统(DCS)相比具有的特点、FCS的网络体系结构,介绍了几种流行的现场总线,提出了将嵌入式Internet技术结合现场总线构建现代测控网络的课题;在此基础上,构建了基于嵌入式Internet技术的测控网络结构模型;深入研究了嵌入式系统的核心硬件—嵌入式微处理器,通过对比普通操作系统,描述了嵌入式实时操作系统的特点;重点研究了实现嵌入式Internet的四种实现方法,并分析了以太网在工业测控系统中应用的难点,给出了一个基于嵌入式IP的网络测控系统实例;最后,研究与设计了一个基于嵌入式Web服务器的远程网络视频监控系统,该嵌入式Web服务器利用目前成熟的嵌入式实时操作系统μC/OS-Ⅱ,通过对μC/OS-Ⅱ进行适当的裁剪、修改与移植,在AT89C51嵌入式微处理器上实现了TCP/IP协议栈及应用程序,系统的成功运行证明了本文研究成果的有效性,也表明嵌入式Internet技术在现代测控网络系统中具有广阔的应用前景和推广价值。
With the Internet and Embedded system being widely used, various kinds of technology such as computer, network,control and field bus are growing up quickly. It makes measure and control network system tending towards more convenience in data sharing,more rapid in information transmition and more friendly in interoperation, and makes control technology become more networking, distributing and opening.
    Field bus is the core of the modern measure and control system.when field bus develops from industry field device up to top and computer networking sinks to bottom device from internet, the network measure and control system based on embedded internet technology becomes true.
    Firstly, this paper makes a detailed study on the Field control bus system (PCS),including the characters of PCS by comparing FCS and DCS, model networking of PCS and several popular Field bus, then put forward a question for discussion combining Embeded internet technology and Field bus and measure and control networking model based Embeded internet technology is constructed.Secondly, it studies Embeded system including the core of hardware梕mbeded microprocessor and real time operation system.Thirdly,the method of realizing Embeded internet is discussed for emphasis,and difficulty of ehernet application in industry measure & control system is analysed.An instance of measure & control networking system based embedded IP is given. Finally, the author designed a networked remote video surveillance system based embedded web server, μ C/OS-II is sacled and ported into the embedded microprocessor AT89C51.Based on the μ C/OS-II RTOS, TCP/IP protocol suite and application program is designed in detail.The system w
    orks well that improves that the embedded internet technology will be widely used in modern measure & control networking system and has extend values.
