摘　　要：为了确保井下采集数据的可靠性,提出了一种通过外接大容量的存储设备实时保存矿井数据采集分站中数据的设计方案。设计中采用ARM Cortex-M3微控制器作为控制芯片,以SD卡作为存储介质,给出了通过SPI方式读写SD卡的方法和相应的文件系统设计。测试表明本设计可靠性高,实时性强,成本低廉,非常值得在井下数据采集中进一步应用推广。To ensure the reliability of data collection underground, this paper presents a design scheme of saving the data in mine data collection substation in real-time through external large- capacity storage device. In this design, ARM Cortex-M3 microcontroller is used as the control chip, and the SD card is used as storage medium. The design offers the method of reading and writing SD card by SPI and the corresponding file system is given as well. The experimental results show the design has the feature of high reliability, real-time, low-cost, and is welt worth of further application and popularization of data collection underground.
