摘　　要：随着社会进步,人们对周围气象信息的准确性和实时性提出了更高的要求,由于市场上的自动气象站价格较高,因而设计了基于嵌入式的小型自动气象站。系统以高性能的ARM Cortex-M3微控制器LPC1788为硬件核心,扩展了外围接口电路。以嵌入式实时操作系统μC/OS-II为软件平台,移植了μC/GUI图形用户界面,实现了数据的采集、处理、存储及显示等功能。通过3G模块与数据监控中心主机进行通信,实现了远程数据实时传输。经测试,系统具有体积小、成本低、功耗低、采集速度快等优点,在气象监测行业中具有广阔的应用前景。With the development of the society,people put forward higher requirements for the accuracy and real-time of the weather in- formation around themself. Due to the price of the automatic weather station on the market,therefore a small automatic weather station based on embedded system is designed. The system uses high-performance ARM Cortex-M3 microcontroller LPC1788 as the hardware core,and expands the peripheral interface circuits. The embedded real-time operating system μC/OS-Ⅱ is used as the software platform, and the μC/GUI graphical interface system is ported to achieve data collection, processing, storage and display and so on. It communicates with the data monitoring center host through the 3G module, and achieves the real-time remote data transmission. The test results show that the system has small size,low cost,low power consumption, acquisition speed, etc, and has a wide range of applications in the weath er monitoring industry.
