摘要
90年代以来,以Internet为代表的计算机信息产业和数据通信网络蓬勃兴起,发展迅速,同样也对工业自动化领域形成了强大的冲击,新型的工业计算机网络如新型集散控制系统(DCS)、现场总线(Fieldbus)、工业以太网(Industrial Ethernet)等大量涌现,给工业自动化带来一场深层次的革命。但现场总线的国际标准未能统一,不同总线产品间并不能直接互连、互用和互可操作,现场总线真正实现开放性任重而道远。随着技术的发展,企业要求工业网络从现场控制层到管理层能实现全面的无缝信息集成,并提供一个开放的基础构架。这时传统以太网逐渐进入了控制领域。
     本文根据工业网络的要求,结合传统以太网技术、交换技术等,研究了工业以太网的控制策略、测试方法、实时调度、网络管理和系统设计等技术问题,分析了工业以太网的冗余设计,提出了理想的工业以太网理想解决方案。
     本文的主要内容包括:
     1、系统介绍了工业网络历史发展和研究现状,对工业以太网和DCS、现场总线进行了比较,介绍了工业以太网的历史发展和背景知识,指出了工业以太网所具有的优势、存在的问题及本文的研究方向。
     2、对以太网控制策略的实施进行了深入的研究,设计了具体的网络配置实例,通过模拟软件进行了仿真,并详细分析了仿真结果;测试了吞吐量、传输时延、故障恢复时延等网络基本性能,并对测试结果进行了定性的分析。
     3、针对传统以太网的不确定性,我们结合现有技术,研究了采用全双工交换式以太网、虚拟局域网、服务质量(QoS)、IPv6等技术提高工业以太网实时性的方法和途径。
     4、根据网络管理系统的特性,深入研究了工业以太网管理系统的体系结构,并对基于OPC的现场获取进行分析,提出了基于XML的远程监控。
     5、分析了工业以太网的核心层和分布层的冗余设计,并给出各种冗余设

After 1990s, information industry and data traffic network have greatly mushroomed and influenced industrial automation. New type industrial networks such as DCS, Fieldbus and Industrial Ethernet have brought a high-level revolution in industrial automation. However because of the disunion of the international standards of Fieldbus and indirect interconnection and interoperation between different kinds of Fieldbus products, the openness of Fieldbus can not be achieved easily. With the rapid development of information technology, the ability of seamless integration between management layer and field control layer is required as well as an open infrastructure by enterprises and consumers. Traditional Ethernet has gradually entered the industrial control field in the same time.
    According to the requirement of industrial network, the scheduling of real-time traffic, Network management, control strategy and test method of Industrial Ethernet were discussed combining traditional Ethernet technology and switching technology in this thesis. We analyzed the analyzed the redundancy design and provided the ideal system design of Industrial Ethernet.
    The main content of this thesis is listed as follows:
    1. Firstly, we make an overview the history and the latest achievement of industrial network and compare Industrial Ethernet with DCS and Fieldbus. We also introduced the history and the development of Industrial Ethernet. We make a discussion on advantages and problems of Industrial Ethernet and pointed out the direction of research for this thesis.
    2. We studied the control strategy of Ethernet in-depth and designed specific example of network configuration; then we emulated the example on simulation software and analyzed the results of emulation in detail. We also tested the basic performance of network such as throughput > transmission latency and fault recovery latency and qualitatively analyzed the results of the test.
    3. To the non-deterministic of traditional Ethernet, we studied the technologies such as full-duplex switched Ethernet network, VLAN, QoS and IPv6 technology in detail, which are used to realize the ability of real-time of Industrial Ethernet.
    4. Base on the characteristic of Network Management System, we discussed
    VI
    
    
    
    the architecture of Industrial Ethernet Network Management System. We analyzed data-obtaining process of industrial field based on OPC and put forward a new remote supervise system based on XML technology.
    5. Lastly, we analyzed the redundancy design of the core layer and the distributing layer of Industrial Ethernet and provided the schemes of redundancy design. At the same time, we discussed the pattern design of Industrial Ethernet, provided the ideal system design of Industrial Ethernet and pointed out the new direction-hybrid system of Industrial Ethernet in the future.
    Finally, we drew a conclusion and propose the future research directions.
    We believe that Industrial Ethernet will have a bright future of application in industrial control field. There are still some key problems needed to resolve. Positive study would be helpful to push Industrial Ethernet forward in application.
