厦门市自动气象站数据通信系统设计

结合厦门市实际情况,在信息传输环节,厦门市自动气象站采集的信息传输更适合采用无线方式完成数据通信。设计了一种基于GPRS网络的多点对单点主从式自动气象站数据通信传输系统。系统中各自动气象站点的数据采集器完成气象要素信息采集,各站点的GPRS通信模块在GPRS网络中通过DDN专线与租用静态IP地址的移动中心服务器构成数据通信传输网络,中心服务器与厦门市气象台网络信息中心通过TCP/IP协议实现实时通信,气象观测终端软件完成数据的存储及加工。截止到2010年9月初,系统已稳定运行8个月。该系统不受传输距离的限制、成本低、建设快,适用于各类气象自动站远程数据传输和控制,提高了气象信息发布效率。

Design of Data Communication System for Xiamen Automatic Weather Stations

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 multi-host to one-client 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 real-time 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.
