【摘要】 随着计算机技术、通讯技术和网络技术的飞速发展的同时,在控制和管理理论快速推动下,管控一体化技术也日益走向了成熟,它在工业监控系统中的应用也十分广泛了。在我们享受其带来的快捷高效时,管控一体化网络自身和其边界的安全却成为一个新问题困扰着我们。本文探讨了对管控一体化网络互联实现的原理和方法,并结合网络安全方面的新技术对管控一体化网络自身及其边界的安全问题进行了讨论,也给出了建构安全的一体化网络的一般模式。在工程实施中以张湾水电站监控系统、江汉油田水厂供水监控系统、中央储备粮赤壁直属库管理监控系统等项目的研制开发为背景,给出了具体的工程实施方案。首先,从理论上分析了控制网和管理网互联的必要性及难点,研究了两者进行互联的原理、机制和方法,归纳总结了各种具体实现的方法,对此进行了比较详细深入的分析讨论。然后,从网络安全的角度来审视管控一体化网络,发现其存在的弱点,并结合目前最新的网络安全技术解决其中存在的一些安全隐患。同时我们提出了纵深防御的思想,并将其应用到管控一体化网络的每一方面。最后,结合前文分析的思路方法,较详细地介绍了上面几个工程项目的总体设计和具体实现,展现了一种结合Internet、Intranet和Infranet的应用模式。每个工程项目中都从管控一体化网络的具体实施到安全的每一个方面都给予了阐述。更多还原

【Abstract】 With the development of the Computer network technology and so on,the Management & Control in one technology became growth rapidly. The technology of joining management network and control network in one, supported by electronic,communication, information technology and management & control theory is developed. Many applications of this kind of technology in monitoring and controlling systems is already in used today.But there are new problems,which we know is Network Security. The thesis mainly investigates the the theory, mechanism and ways of the technology of Management & Control in one. At the same time we also discusses the new problem of the Management & Control in one which we call Security of the network.And we have give some nice tips to solve the problem which we have find.This thesis is based on three projects, they are the monitoring and control system for ZhangWan power plant, the water monitoring and control system for Jianghan oil field, and the integrated monitoring and control system for Puqi national grain depot. At first, this thesis analyzes the necessary and difficulty of joining management & control together, discusses the principles, mechanism and methods of interaction, and concludes some actual ways. At the same time the argumentation is investigated in details.The second,this thesis give a new look to the Management & Control in one from another aspect which we know Network Security.Also in some part,we give you a new concept of Network Defence from all aspects.The last part of the thesis introduces the layout and design of the above three project in detail. The introduction shows a method to joining Internet, Intranet and Infranet. At last of the thesis, it views the prospect of technology of Management & Control in one.更多还原
