In order to achieve the goal of integrating provincial meteorological service data resources and unifying meteorological service export, promote the efficient application of meteorological data products in disaster prevention and public services, based on the Spring Cloud framework, the Hunan meteorological service platform is developed using Software Plugin, WebSerivce and other technologies. This paper introduces the layered model and functional structure of this platform and the key technologies such as multi-source meteorological data fusion processing, data parallel processing based on microservice, data vectorization based on SVG, and data secure interaction. The platform obtains meteorological data from CMADaas, packages them into the data plugin, graphic plugin and speciality plugin, provides meteorological products such as observation data, forecast, early warning, satellite cloud and Radar images through standard interfaces, and ensures the security of meteorological products service process based on MOID. The meteorological service plugin of this platform has been applied to the application systems of the Hunan Emergency Management Department, Natural Resources Department, Water Resources Department and other units. Application results indicate that the plugin service mode of this platform is suitable for different types of meteorological service needs, such as C/S clients, websites, and mobile apps. It realizes the unified management, efficient processing and standardized application of meteorological services and improves provincial meteorological service capabilities.
