摘要:
设计了一种新型海洋要素数据采集系统的SD卡存储方案。该方案选用与8051完全兼容的高性能单片机C8051F340作为主控制器，采用SPI总线与SD卡通信。介绍了SD卡以及C8051F340芯片中SPI接口的结构和工作原理，讨论了相关的设置、硬件连接和软件设计，实现了对SD卡的读写，解决了海洋数据采集过程中，数据存储量大、存储设备不易与PC机接口的问题。

The application of SD memory card to an ocean data storage
Abstract:
A new scheme of SD memory card applied to the ocean elements storage system is designed. In this design， the SOC C8051F340 is used as a host controller and communicates with SD memory card on SPI Bus.The structure and principle of the SD memory card and SPI Interface with the C8051F340 are introduced, and the hardware and software designs are discussed in this paper. The problems of large data storage and interface with PC computer are solved by the system.
