Abstract
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 systemμC/OS-II is used as the software platform, and theμC/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.关键词
