    摘要:

    针对多颗气象卫星数据在国内外地面站兼容接收及统一自动批量预处理的业务需求,基于观察者模式,设计了系统总体架构,构建了数据接收任务、质量文件传输、预处理与分发作业运行调度机制,实现了有效协同各种资源,对气象卫星多个有效载荷观测数据进行同步自动批量接收、传输、预处理与分发。经过实践检验,该机制简化了设计,降低了耦合度,增强了系统健壮性,满足业务调度的灵活性、可靠性、时效性要求,同时监视界面直观明了,可操作性强,为气象与气候领域的科学研究提供了持续有效的海量数据支撑。

    Abstract:

    According to the business requirements for the meteorological satellites data acquisition and automatic batch preprocessing, a new scheduling mechanism on acquisition and preprocessing of meteorological satellite data based on observer pattern is proposed and implemented, and the overall architecture of the system is designed. The results of application test prove that the design is simplified and the degree of coupling is reduced, the robustness of the system is enhanced, and can meet the performance requirements (flexibility, reliability and timeliness). It realizes the automation of acquisition, transmission, preprocessing and dissemination of meteorological satellite data, and the monitoring interface is in good visualize and can be manipulated easily, providing effective and continuous meteorological observation data for scientific research.
