By analyzing current status and existent problems of automatic weather monitoring system, and based on the general packet radio service and network communication technology and data processing technology, a new, safe, reliable system was designed on the rapid data transmission and information concurrent processing of a large amount of automatic weather station. The system design thought, communication means, network architecture, transmission protocol, workflow, software design, technical characteristics were described in detail. It is a good system design method that is able to guide the development of other largescale, unattended, realtime data acquisition, data burst transfer application systems.
