【摘要】 论文依据对西固热电厂2*142WM机组生产信息管理系统技术方案设计项目的设计研究，在如下几个方面进行了研究设计工作：生产信息管理网络系统构架的研究，网络系统设备的选择。该论文是生产信息管理系统设计方案的重要组成部分，为西固热电厂2*142WM机组生产信息管理系统的具体实施提供了详尽的参考。 信息管理系统(MIS)是一个对管理信息进行收集、传送和使用的系统。从五十年代发展开始至今，信息管理系统已从单一的应用发展到综合应用，从简单处理深入到复杂处理。信息处理模式已从集中式、分散式发展到分布式，应用任务正从大型主机系统转移到客户机／服务器为支撑的分布式网络上来。 任何一个信息管理系统都有自己的载体，就是网络的架设、设备的连接、系统的配置。信息管理系统的构架设计一般主要包括网络构架的层次设计、网络的数据交换层次设计、网络构架的一些相关问题的设计以及主干网类型的选择等方面。本文根据这一设计思想，根据本厂的实际情况和实施网络构架设计时遵循的基本原则，对集中式网络构架的方案设计和分布式网络构架的方案设计进行了对比，提出了分布式网络构架方案设计的构想。 对于网络设备的配置，本文综合对比了基于以太网网络构架的设备的配置选择和基于ATM网络构架的网络设备选择，这为以后西固热电厂的信息管理系统的改造以及重建提供了可供选择的方案。 对于系统实现方法方面，本文在对比了一些其它方法后，提出了MMS的概念并对其实现方式进行了详尽的述说。为本厂信息管理系统的实现奠定了坚实的基础。更多还原

【Abstract】 Based on the research of the technical project of the MIS which is for the 2 142MW unit of Xigu thermal power plant , the paper provides some original views in the following aspects: the research of information management system framework, the choice of network system devices, Being the important part of the information management system project, the paper provides particular reference for the application of the information management system about the 2 142MW unit of Xigu thermal power plant. MIS is a system ,which collects,transmits and uses the management information. From 1950s to nowadays,MIS had developed from single application to compositive application, from simply disposal to complicated disposal. The mode for dealing with information had developed from centralized style , dispersive style to distributed style, the applied task is diverting from the large main computer to dispersive network which is sustained by client/server. Every MIS has its own carrier, it is the framework of a network, the connection of device and the ordonnance of system. In general,the design of network construction of MIS include design of administrative levels of network,design of administrative levels of data exchangement of network and design of selection of main network style. According to the fact of our factory and the principle must be followed when we actualize the design of network construction, Compared two schemes and then bring the dispersive network framework forword. For the ordonnance of net work , this paper compared the selection of equipments which based on ETHER and the selection of equipments which based on ATM, so there two schemes we can select. For the way of realization about the system, this paper brought MMS forward and made a full description about it.更多还原
