Optimal Design of SD Card Storage Performance Based on MCU: Hubei Province environmental protection automobile oil pipe intelligent manufacturing enterprise and school joint innovation center

In previous SD card-based data acquisition and processing experiments, due to the chain storage structure of FAT32 file system, SD card occurred data interspersion when collecting massive data, resulting in SD card storage errors Therefore, this design based on embedded microcontroller FDT FAT file system are realized by programming and DATA stored in order, and by increasing the number of DBR sector to achieve redundancy cycle in order to increase the service life of the SD card, at the same time the new SD card error detection and error correction function, can effectively enhance the SD card on huge amounts of DATA acquisition and processing of real-time and reliability.
