摘　　要：传统的以手工方式从世界气象组织每周在其FTP平台上发布的台站信息文件进行数据的收集、归档、管理已经无法满足实时更新的需求,且人工方式极易产生信息的错漏。为此,结合全球台站信息表的特性和FTP协议,集台站信息文件发现与下载、信息自动对比、实时资料更新与归档等任务模块于一体,设计并实现了全球台站信息自动更新软件。通过软件在国家气象信息中心的实际运行效果显示,采用此软件后全球台站信息的更新周期从数月缩短为十五分钟以内,可为入库资料的完整性、实时性和准确性提供基础保障。World Meteorological Organization （WMO） publishes the new station information table on FI＇P weekly, and there is no complete global stations automatic update processes. The update cycle is too long and apt to cause information error by using artificial process, and cm＇~nt process cannot meet the demand for real-time updating. In this paper, combined with the characteristics of the global station information table and FrP protocols, automatic update software of the global station information was designed including station information file finding and download, information auto-contrast, real-time data updates and archiving. The software has been put into operation. By using this software the update cycle of global station information reduces from several months to 15 minutes, and it ensure the data integrity of the Meteorological Data Storage System （MDSS）.
