Abstract:Based on the rainfall data from AWS (Automatic Weather Stations) and the village and townlevel automatic precipitation stations, the Meteorological service, Monitoring and Autoalarming System was developed. Taking the database as the core, this system, by means of the basic meteorological service communication network and the client/server pattern, realized such functions as the regional areal precipitation appraisal, the monitoring of data gathering from village and townlevel automatic precipitation stations, the autoalarming of rainfall intensity according to the precipitation grades in the specified time periods, the realtime storage of AWS data, and the autodrawing of various color meteorological charts, etc. An introduction is made to the system structural design, the objectives of various subsystems, and the principles and methods for realizing various functions.
