摘　　要：珠海塔台华泰自动化系统因故障部分功能缺失,值班员通过查询系统重要模块状态、分析系统日志,发现该系统珠海进近分区主用通信服务器缓存区脚标异常增长,且未清零,导致大量数据未经转发就被覆盖重写,从而出现珠海塔台分区数据异常的现象。在珠海进近分区切换通信服务器主备机后,系统恢复正常。通过分享案例,文章分析该系统不同分区的数据同步机制及现有缺陷,为相关单位运维该系统提供经验,提高突发情况下的应急处置能力。Due to malfunction,some functions of the Huatai Automation System in Zhuhai Tower are missing.The duty officer found through querying the status of important modules in the system and analyzing system logs that the main communication server cache area footer of the Zhuhai approach partition in the system grew abnormally and was not cleared,resulting in a large amount of data being overwritten and rewritten without forwarding,resulting in abnormal data in the Zhuhai tower partition.After switching between the main and backup communication servers in the Zhuhai approach partition,the system returned to normal.This article shares a case to deeply explore and analyze the data synchronization mechanism and existing defects of different partitions of the system,providing experience for relevant units to operate and maintain the system,and improving emergency response capabilities in emergency situations.
