Design And Implementation Of Doppler Weather Radar PUP Products Sharing System

Social progress and economic development has brought about growing concern regarding weather forecast. Weather forecast and associated meteorological services have covered all aspects of social economy and people’s life. As a new means of detection, Doppler weather radar has mainly been applied to monitor and warn typhoon, rainstorm, hail, tornadoes and other severe weather. It is able to reflect the current actual weather and the weather change trend timely and accurately. Therefore, the research of Doppler weather radar PUP product sharing system, to a certain region geographically dispersed radar stations call combined display of various products, is of great significance for improving the ability of meteorological forecast service. Papers to the Doppler radar product generation mechanism and the province’s meteorological information network system as the foundation, has analyzed the current radar product sharing system problems, according to the radar PUP product processing process, the design architecture of radar product sharing.According to the provincial meteorological services to information management and sharing needs and current situation of weather, combined with practice practical exploration of Sichuan Province, puts forward a complete set of meteorological information management and sharing system model-- the establishment of intensive meteorological database, huge amounts of comprehensive meteorological information for effective management, in order to provide efficient location, weather the data retrieval service. In order to solve the problem of data sharing, system uses message oriented middleware technology, through the two development, provide convenient variety of data access interface, on one hand makes the database security and access efficiency is guaranteed, on the other hand, support for data base access to a variety of different development environment, the meteorological information open sharing service implementation. The system adopts the application architecture of client middleware database communication system, the client is mainly responsible for the data display, the user understand the radar product data collected by the client; middleware as the medium before the system user and the database, the main purpose is to provide a standard interface for users to access all kinds of database, ensure the database information security at the same time specification all kinds of access, convenience for users, achieve shared goals; database provides the data storage and query support; communication system is mainly responsible for the collection of Radar Product data is stored in a database.The result of the system shows that, this system can be used in the whole system of meteorological forecasters in professional, so as to be able to let the forecasters have full understanding of weather trend, selected location and area to increase the accuracy of the forecast of the meteorological department is very helpful, to achieve the expected goal.
