Abstract: With the rapid development of modern meteorological observation technology, the quantity and type of meteorological data is increased sharply. At present, the FTP file transfer method based on traditional TCP/IP protocol and pure text message file in TXT format can no longer meet the high-time transmission and storage requirements of large quantity and multi-type observation data. To meet the needs of meteorological informatization standard system construction, this paper studies the Java message service transmission and new technology development and application of XML data file formats in AgMODOS including the message middleware technology, message transmission architecture design, observation data message filtering and encapsulation, data cache and data supplementary transfer etc. in RabbitMQ message queue technology. The results of the trial operation of the service show that the CONTENT of the XML format file is correct, the message transmission is stable, and there is no loss. 99% of the observation data are transmitted from the station to the national bureau within 1s, and the data are transmitted to the business unit timely through the exchange control strategy, and the timeliness and service capacity of the agricultural meteorological observation data transmission are greatly improved.

Key words: Agrometeorological observing data operation system, XML data format file, Java message transfer
