摘　　要：根据某新型装备特点,介绍了一种基于ARM Cor rex-M3和SD卡的数据采集系统的硬件设计和软件设计;硬件部分包括信号调理电路、微控制器外围电路和SD卡接口电路3个方面;其中微控制器是基于ARM Cortex-M3微处理器设计的STM32F205VG,该设计采用微控制器自带的ADC模数转换器完成模数转换;软件部分包括系统软件和应用软件两部分,其中系统软件主要有主程序模块、初始化程序模块等;应用软件主要有信息采集、SD卡读写程序等;该系统设计采用ARM微处理器,充分利用了ARM的低功耗、高效率、体积小的优点,具有广泛的应用前景。The primary goal of this research is to introduce an information collection system design based on ARM Cortex--M3. The main point of this paper employs hardware design and software design. Hardware part includes adjusting circuit, micro controller and SD card. The micro controller in hardware part is STM32F205VG which designed based on ARM Cortex M3 microprocessor, and adopts built --in AID converter to finish ADC conversion. Software part consists of system software which includes main program and initializer, and utility software containing information acquisition program and the reading and writing of SD card. Employing ARM microprocessor, conversion system makes full use of the ARM＇s advantages： low power consumption, high efficiency and small volume, which of course has promising application prospect.
