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.
