摘　　要：为了解决自动气象站采集器嵌入式应用程序维护、扩展困难的问题,提出了一种基于构件的可配置嵌入式应用程序设计模式,把传统的嵌入式应用程序拆分成功能构件、框架构件、配置构件和解析器,通过组装构件的方式开发应用程序;实验程序实现了数据采集、数据质量控制、数据计算、数据存储和基本的通信协议;并且基于此套设计模式,可以方便地进行气象要素和导出量的配置,或者对软件的功能进行扩展;实验结果表明,此套设计模式大大地提高了嵌入式应用程序的易维护性、易扩展性以及开发效率。To solve the problem of the difficulties of maintenance and expansion of embedded application program in the collector of automatic meteorological station, it proposes a component--based design mode for configurable embedded application program. It splits traditional embedded application program into function component, frame component, configuration component , parser and develops application program by assembling components. The test program realizes data collection, data quality control, data calculation, data storage and basic communication protocol. And based on this set of design mode, it can also configure meteorological elements and derived quantities or expand the functions of software conveniently. The result of the experiment shows that this set of design mode improves the maintainability, expansibility and development efficiency of embedded application program greatly.
