基于GPRS技术的自动气象站数据采集系统

GPRS based AWS Data Acquisition System

针对采集数据要求,建立了基于GPRS技术的广东省自动气象站采集系统。在分析自动站探测业务需求基础上,着重介绍了系统总体结构的设计思路以及主要设备的配置方案,叙述各个软件子系统的功能作用和流程,并给出实际具体的流程关系图,采用模块化结构、标准化接口编程,实现系统的可扩展性、可维护性。指出选择GPRS移动通信终端(DTU)需要注意的几个问题。在实际应用中,系统的处理能力达到4000个/min自动站资料的并发上传。

A GPRS technology based AWS Data Acquisition System （ADAS） has been established for over 800 AWS stations in Guangdong. This paper gives a thorough analysis on the operational requirements, outlines the overall architecture of the system, recommends configurations for the major devices, and describes the functionalities of the sub - systems and their linkages by a detail flow chart. Modularized design and standardized programming interface are adopted by ADAS to make it scalable and maintainable. Some issues about choosing GPRS mobile communication terminals （DTU） are also discussed here. In practice, the processing capacity of ADAS can be as much as 4000 pieces per minute for simuhaneously data uploading.
