The mostly task of this paper is to take all the advantage of web technology to reconstruct the traditional monitor system of dcs , so that the monitor system can be more powerful in process control , more advanced in remote monitor and easier to access the network . first , web technology and development technology based on web technology is simple introduced . then , three kind of application of web technology in industrial control was introduced . first is some preparatory research i have done in opc - xml criterion 文章首先简单介绍了web技术以及基于web的开发技术，然后分别介绍了web技术在控制系统中的三种应用，包括对opc - xml规范做的一些初步研究，希望能把它用于基于internet的现场底层数据传输和发布，在基于epa的分布式网络控制系统中实现基于xml的设备描述技术，最后详细介绍了dcs远程监控模块的软件设计实现。
Then , adopting xml language , rss 、 asp technology of developing dynamic website and referring to some functions of intelligent - agent , this research constructs a systematic individualized network learning environment , and describes the design principles and tactics of the five modules of individualized network learning environment in a systematic way , which are : the module of individualized course pre - examination ; the module of individualized interface ; the individualized course design ; the module of cognitive tools ; the module of personalized learning control 用系统的方法描述了个性化网络学习环境的五个模块的设计原理与策略,分别为:个性化课程前测模块;个性化界面模块;个性化课程设计模块;个性化认知工具模块;个性化学习监控模块。最后,笔者为了进一步解释各个模块的设计理念、技术与策略,简单的制作了一个个性化网络学习环境案例,并对几个模块中的个别功能做了简要叙述。
Then the article introduces the design and realization of user level monitor module and kernel level monitor module detailedly , including how to realize the system clipboard monitor , the file motion control , file print job interdiction , and the directory share monitor in system ’ s user level , how to realize the process accessing filter , the process privilege control , the file encryption and decryption in system ’ s kernel level 本文详细给出了用户层监控模块和内核层监控模块的设计和实现,包括如何在操作系统用户层实现系统剪贴板监控、文件移动控制、共享目录监控、文件打印阻断等,如何在内核层实现进程访问过滤、用户进程权限控制、文件透明加解密功能。
And the paper also gives a suggestion that the security problems be resolved through security socket layer ( ssl ) , etc . finally , the paper makes a case study on the controlling system to build the infranet at the steel - making workshop at orient steel co . based on a subsystem - monitoring platform for the steel - making facilities designed by the author by using a controllogix plc of rockwell company and ifix of intellution company 本文最后以东方钢铁公司炼钢车间的工业控制系统为研究对象，结合作者利用ab公司的controllogix系列plc和intellution的ifix上位监控软件来搭建上业控制网络组成现场监控模块，设计了基于互联网的远程炼钢车间控制系统。并进行了系统的应用分析与研究。
( 4 ) it presents the architecture and basic function of haecs . it fulfills primary modules , which includes management and control interface , not only monitoring the state s of real nodes , but also the state of the service modules . it will delete it from the server table reside at the director when the real server or the service does n ' t work properly 完成了linux系统上的图形管理控制界面，以及真实服务节点的服务功能监控模块，监控模块不仅能够监控服务器的状态，还可以监控服务模块的状态，一旦服务失效能够及时地将该服务器从集群节点中删除，在监控状态中，模块可以定时采集服务器的状态信息，根据各个服务器的状态，采用负载加权算法来动态的管理集群，实现集群的智能管理。
The article laies a strong emphasis on description of the realization mechanism which is used in the file realtime monitor module of tfss 。 tfss runs on win2000 or other higher version platforms . according to these systems ’ structure characteristic , double - level monitor mechanism is used in file realtime monitor module . the double - level monitor mechanism ensures tfss monitor function ’ s stabilization and greate efficiency Tfss系统应用于win2000及以上版本操作系统,文件实时监控模块根据此类操作系统结构特点使用了双层监控机制即用户层监控和内核层监控,双层监控机制保证了tfss系统能够稳定、高效、全面地实施监控功能。
The focus of this thesis is on the introduction of the software architecture of the new system , including selecting the appropriate development flat , pc communicating principle , its own software modules and the respective functioning principles of the related parts . besides , some modules are offered such as a universal data encoding and decoding module , a power management module and a remote monitoring module 然后，对基于m - bus的水表联网抄表系统的软件构成包括开发平台的选择、 pc通讯机制、系统的模块组成和相关部分的实现原理进行了重点的描述，给出了一个通用的数据加密、解密模块，权限管理模块和远程监控模块。
Remote monitoring : administrator could remotely get user operations and host status , kill process on hosts , lock / unlock hosts and shutdown hosts . network monitoring : detecting illegal hosts and sniffers , supporting across sub network monitoring , and blocking network connecting of illegal hosts . in additional , the identification - authentication mechanism based on user / password 本文首先介绍了网络安全管理系统的运行环境,体系架构和数据库的结构,然后详细介绍了用户身份认证,用户权限管理,网络监控模块的基本原理和具体的实现技术,最后介绍了系统的测试过程。
Through careful analysis of the computer - related technologies , i find out some relatively advanced technologies for the development of information management of intellectualized odf . also in this process , i find out some ways to solve some problems in the system . first , to sample , analyze , process , store and communicate data through the automatic operation of single chip micyoco used in the module for supervision of power in the optic fiber 本文通过对相关计算机技术的研究，得出了开发智能光配线架管理信息系统较为理想的计算机技术，并对它们提出解决的方法：一、在光功率监控模块中采用单片机作自动控制，完成数据的采样、分析、处理、存储、通信；二、采用delphi6 . 0完成管理信息系统( mis )的开发；三、采用c / s数据库结构，以microsoftsqlsever2000作为数据库引擎；四、通过mapinfo公司提供的mapx组件嵌入到delphi中，以delphi作为开发语言完成地理信息系统（ gis ）的开发，同时完成mis和gis的无缝连接。
