中文摘要: |
为提高多普勒天气雷达资料处理效率,基于消息中间件技术、数据缓存等技术,开展了雷达资料处理与组网拼图技术应用研究。采用RabbitMQ消息中间件,实现雷达资料质量控制、网格化处理、数据缓存等实时调度处理。采用多进程技术,实现雷达资料组网拼图和可视化绘制。在此基础上,构建分布式并行业务运行系统,对江西省8部多普勒天气雷达进行组网拼图处理,实时制作时空分辨率分别为6 min和0.01°的雷达拼图产品。基于消息的雷达拼图技术显著提高了数据处理时效,满足了天气监测预警等精细化气象业务服务需求。 |
Abstract: |
In order to improve the efficiency of Doppler weather radar data processing, based on message middleware technology, data caching and other technologies, radar data processing and network mosaic technology methods were studied. The real time scheduling processing such as radar data quality control, grid processing, and data caching was realized using RabbitMQ message middleware. Radar data network puzzle and visualization drawing were realized by the multi process technology. On this basis, a distributed parallel business operation system was constructed to conduct network mosaic processing on 8 Doppler weather radars in Jiangxi province, and real time production of radar mosaic products with temporal and spatial resolutions of 6 min and 0.01° respectively. The message based radar network puzzle technology significantly improved the timeliness of data processing and met the needs of sophisticated meteorological services such as weather monitoring and early warning. |
