Abstract:
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 SystemThis system uses Beidou satellite to distribute warning information in broadcast manner with enormous coverage and guaranteed timelinessIn 2015, BMWIDS began trial operation in Hubei Province with 140 Beidou warning terminals installed and used in Zigui CountyThis 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 distributionThe key technology of BMWIDS includes satellite broadcast, encoding and protocol, message compensation and error correction, as well as service configurationThe comparison is conducted between BMWIDS and other distribution media currently used in Zigui, which are mobile short message, meteorological loud speaker and meteorological LED screenThe service capability and management level of Zigui meteorology are improved by the application of BMWIDSIt is a valuable experience for the implementation and operation of warning information distribution systems based on Beidou satellites in the future
