摘要:省级新一代气象通信集群系统维护期间将造成各类气象信息的传输中断。为确保气象业务系统的连续稳定运行,需要建立单机备份系统,承担维护期间通信业务。该文介绍了辽宁省级通信系统架构及主要功能,分析了单机系统的技术需求,提出了单机系统的设计思路,对单机备份系统的具体实现主备系统切换进行了阐述。单机备份系统作为新一代气象信息系统的应急备份措施,切换简单省时,对业务影响小,为保证实时气象业务不间断提供了重要保证。

Abstract: The maintenance of the new generation of the new generation communication cluster system will result in the interruption of all kinds of meteorological information. In order to ensure the continuous and stable operation of the meteorological service system, a single machine backup system is required, which is responsible for the maintenance of the communication service. This paper introduces the architecture and main functions of Liaoning provincial communication system, analyzes the technical requirements of the single machine system, and puts forward the design idea of the system. As a new generation of meteorological information system emergency backup measures, the single machine backup system is simple and time saving, and has little effect on the business, so as to provide an important guarantee for the real time meteorological service.

Key words: communication; transmission; continuous; single machine; backup

1 概述

随着国内气象观测的不断发展,气象资料种类和数量不断增加,各类气象业务对数据传输时效和质量要求也不断提高[1]。整合了CMACast系统的省级新一代通信系统承担省级上行气象信息的收集、向国家气象信息中心进行数据转发、省际共享、接收和处理国家气象信息中心下发的各类气象数据,向省内各级用户提供业务数据的任务。它采用集群架构,由多台计算机和网络设备组成。由于集群系统整体维护期间需要停机,时间长达2-3小时。由于气象通信业务属于实时不间断业务,因此必须要有备份措施确保维护期间实时业务不间断。

2 备份系统技术需求分析

IP地址需求。省级新一代通信系统以及CMACast系统的IP地址由中国气象局统一规划,各级气象台站、周边省、国家气象信息中心均通过该IP地址进行数据交换,因此,IP地址应不更换为宜。……
