气象网络方案的设计与规划

The design and planning of meteorological network scheme

分析银川河东机场气象网络日常运行状况及拓扑结构,总结现有网络设计方案的优缺点,采用层次化设计思想,提出基于三层网络框架进行设计的网络拓扑结构。对影响网络设计结构的因素如电力部署、用户需求(规模)、配线架端口数量等因素进行深入分析,结果表明:电力部署位置决定核心层汇聚层网络设备位置;主用设备、备用设备、发报设备的分布情况、用户分布以及配线架端口数量决定接入层网络设备分布。本文总结归纳影响网络拓扑结构的因素,规划设计新航管楼气象网络方案,并对方案进行实施和验证。

In this research,we analyze the daily operation and topology of Yinchuan Hedong Airport meteorological network,this paper summarizes the advantages and disadvantages of the existing network scheme,then adopts a hierarchical design idea,proposing a network topology structure that based on the three layer network framework. The factors that affect the network design structure,such as power deployment,user requirements（scale）,the number of distribution terminals and so on,are analyzed in depth. The results showed that that the power deployment location determines the core layer or distribution layer network equipment position;the main equipment and standby equipment,transmission equipment distribution,user distribution and the frame number of ports determines the network access layer distribution equipment. This paper summarizes the factors that affect the topology of the network,planning and designing the meteorological network scheme,and implementing and validating the scheme.
