| Abstract: | 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 well worth of further application and popularization of data collection underground. |
