Abstract:
Considering the actual situation of Xiamen, from the view of meteorological information transmission, the wireless communication solution is suitable for processing the data acquired by automatic weather stations (AWS). Based on the GPRS network, a multihost to oneclient data communication system for AWSs is presented. The meteorological element information acquisition is achieved by the data acquisition devices of various AWSs. The central server of the mobile company with static IP communicates with each GPRS DTU of AWSs through DDN in the GPRS network. The realtime communication is implemented between the central server of the mobile company and the network information center of the Xiamen Meteorological Observatory by TCP/IP technology. Data storage and processing are accomplished by the terminal meteorological observation software. By September 2010, the system has run over 8 months in good stability. The system is not limited by transmission distance with low costs, suited for the data acquisition and control of various kinds of AWSs, and can improve the efficiency of meteorological information releasing.
