基于插件技术的湖南气象服务平台设计与实现

为达到整合省级气象服务数据资源、统一气象服务出口的目标，推动气象数据产品在防灾减灾和公共服务中的高效应用，基于Spring Cloud云架构，采用软件插件（Plugin）、WEB服务（WebService)等技术研发了湖南气象服务平台。本文详细介绍了此平台的分层模型和功能结构，以及所采用的多源气象数据融合处理、基于微服务的气象数据并行处理、基于可缩放矢量图形（Scalable Vector Graphics,SVG）的气象数据矢量化和数据安全交互等关键技术方法。此平台通过天擎获取气象数据产品，统一加工处理后封装为数据插件、图形插件和行业插件，通过标准接口提供观测资料、预报预警、卫星云图、雷达拼图等产品，基于气象数字对象标识符（Meteorological Digital Object Identifier，MOID）保障气象数据产品服务过程的安全性。此平台的气象服务插件已应用于湖南省应急管理厅、自然资源厅、水利厅等单位的业务系统。应用结果表明：此平台的插件服务模式适应C/S客户端、WEB网站、移动APP等不同类型的气象服务需求，实现了气象数据服务的统一管理、高效加工和规范应用，提升了省级气象服务的能力。

Design and Implementation of Hunan Meteorological Service Platform Based on Plugin Technology

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.
