NEC集群管理在民航空管数字通播系统中的应用

Application of NEC Cluster Management in Civil Aviation Air Traffic Control Digital Automatic Terminal Information System

数字化自动航站情报服务系统(Digital Automatic Terminal Information System,以下简称数字通播系统或D-ATIS)通过合成语音(Text-to-voice)和地空数据链两种方式向飞行员提供起飞和降落阶段所需要的有关机场气象情况和机场状况信息。目前民航云南空管分局使用的数字通播系统是基于NEC EXPRESSCLUSTER集群管理的双服务器构架,文章从数字通播系统的结构和NEC EXPRESSCLUSTER集群出发,详细介绍了NEC集群的配置步骤,最后结合实际运行中NEC集群异常的情况给出了相关应对措施。

Digital automatic terminal information system(hereinafter referred to as DATIS)provides pilots with information about airport meteorological conditions and airport conditions required for takeoff and landing stages through text-to-voice and ground-to-air data link.At present,the DATIS used by the Yunnan Air Traffic Control Branch of Civil Aviation is based on the two-server architecture of NEC EXPRESSCLUSTER cluster management.This article starts from the structure of the DATIS and the NEC EXPRESSLUSTER cluster,and provides a detailed introduction to the configuration steps of the NEC cluster.Finally,relevant countermeasures are given based on the abnormal situation of the NEC cluster in actual operation.
