摘　　要：北斗气象预警信息发布系统是中国气象局依托"基于北斗导航卫星的大气海洋和空间监测预警应用示范工程"建设的新型预警信息发布系统,它通过北斗卫星,以广播的方式发布预警信息,发布范围广,时效有保障。2015年,该系统在湖北开展示范应用,秭归承担了140个北斗预警终端的部署和使用。本文介绍了该系统的构成和核心技术,从终端部署、业务管理、信息发布3个方面,总结了系统在秭归的应用。与秭归现有手机短信、气象预警大喇叭、电子显示屏发布手段进行了比较。北斗气象预警信息发布系统在秭归的应用,提高了秭归气象预警服务能力和管理水平,为未来基于北斗卫星的预警信息发布系统建设和运行积累了宝贵经验。The BeiDou Meteorological Warning Information Distribution System（BMWIDS）is a new type warning information distribution system established by the China Meteorological Administration,which is supported by a project Atmosphere Marine and Space Monitoring Early Warning Application Demonstration Project Based on BeiDou Navigation Satellite System.This system uses Beidou satellite to distribute warning information in broadcast manner with enormous coverage and guaranteed timeliness.In 2015,BMWIDS began trial operation in Hubei Province with 140 Beidou warning terminals installed and used in Zigui County.This paper introduces the system architecture and key technology of BMWIDS,and illustrates its application in Zigui in three aspects：terminal installation,service management,and information distribution.The key technology of BMWIDS includes satellite broadcast,encoding and protocol,message compensation and error correction,as well as service configuration.The comparison is conducted between BMWIDS and other distribution media currently used in Zigui,which are mobile short message, meteorological loud speaker and meteorological LED screen.The service capability and management level of Zigui meteorology are improved by the application of BMWIDS.It is a valuable experience for the implementation and operation of warning information distribution systems based on Beidou satellites in the future.
