Design of expendable conductivity temperature depth survey data processing system

A scheme of economical and easy to carry XCTD survey data processing system is designed. In this design, the Cortex-M3 core-based high-performance processor STM32 is used as a host controller and communicates with SD memory card on SPI Bus. lt establishes FAT32 file system. So the problems of large data storage and interface with PC are solved by the system.
