According to the research , the last part emphasis on two aspects of the lns service : building a lonworks network , monitoring and controlling network using single point monitoring 此外,还根据课题的涉及内容,重点介绍了基于lns模式的网络组建,设备安装,以及网络变量绑定等内容。
We thoroughly discussed the architecture and design process of the fieldbus monitoring and control network , and we also studied the dp interface programming according to the problem met in the design process 作者详细阐述了监控网络的组成结构和设计过程,并针对设计中遇到的问题对dp接口编程做了相关研究。
Monitor and control network ' s construction can not be achieved by piling up safety product and some technique in brief , so with the concept of the system engineering , i research the whole solution of the monitor and control network safety finally 由于网络安全建设并不是技术和安全产品的简单堆砌,所以最后采用系统工程的概念,研究了监控网络安全的整体解决方案。
The design thought is : on the basis of the previous catv network , to add a main control unit at the mixer part , and embed a node units in each dual - direction amplifier , accordingly , consititue a safe monitoring and control network 设计思路是在原有的有线电视网的混合器部分外加一个主计算机控制单元,并在各放大器部分分别嵌入一个节点控制单元,从而构成一个监控网络。
Web - based management , wbm in short , is a kind of new tri - layer architecture . manager can monitor and control network ' s state conveniently and flexibly by using wbm , and this technology can also bring good performance and expandability to nms 基于web的管理模式是一种全新的三层结构,它不仅让管理员能够方便灵活地监控整个网络的状态,而且这种模式具有良好的性能和可扩展性。
Network management is to control and optimize the operation of the network and to respond to changing user requirements . the management includes the control and monitoring of the network . to satisfy this requirements , different management standards are developed , such as java management extensions , which a good management architecture that developed by sun microsystems , inc . based on java management extensions , we develop a set of agent network management system . by the system , users can monitor and control network resources through web browser 随着网络的迅速发展,新技术、新设备层出不穷,网络的构成也日趋复杂。为了网络的正常运行和服务质量的保证,对网络的有效管理也越来越重要。网络管理就是根据用户的需要控制并优化网络资源,包括对网络的监视和控制。
In this text the basic theories and the applied truss of the network monitor and control the system are discussed firstly , the inevitability is also analyzed about monitor and control network facing with the frequent safety threaten . then i research each safety aspect of network remote monitor and control system through academic study , engineering practice and a lot of simulation experiment . at the same time i research deeply and systemically in the popular virus problems and the dangerous hacker ' s attack 本文讨论了网络监控系统的基本理论和应用构架,分析了监控网络面临经常的安全威胁的必然性,然后通过理论研究、工程实践以及大量的模拟实验,对网络远程监控系统安全性问题的各个方面进行了广泛的研究,对其中最常见的计算机病毒问题以及最可能造成严重危害的黑客攻击问题进行了深入系统的研究。
In the paper , we first analyzed the birth of fieldbus and its characteristic and excellences , then we thoroughly studied the network architecture and communication protocol of profibus and as - i . on the foundation of above works , we designed a small but applied fieldbus monitoring and control network , which provides a ideal study and experiment platform for the application of profibus and as - i technology 本文首先分析了现场总线的产生原因及其特点、优点;接着着重研究了profibus - dp和as - i总线的网络体系结构和通信协议;然后在此基础上设计了一个小型的功能齐全的现场总线监控网络,为profibus - dp 、 as - i总线技术的应用提供了一个理想的研究实验平台。
