【摘要】 为满足海洋多参数浮标的需要,设计了一种采用低功耗芯片MSP430F149为核心的小型数据采集系统,能自动完成水温、气温、气压、波浪、风速、风向的水文气象参数的采集、处理、传输等功能。本文介绍了基于CF卡的数据存储部分的设计,包括基于低功耗单片机MSP430F149和CF卡的软硬件接口设计和FAT文件系统的编写。实践证明,该数据采集系统工作稳定可靠,CF卡上存储数据文件可以被Windows操作系统读写。更多还原

【Abstract】 A small data acquisition system is designed for the multi-parameter marine buoy,which is based on a low power chip—MSP430F149.The system can sample,process and transfer such data as temperature,water wave,air pressure and wind.A CF card based data storage scheme and the design of its interface are described in detail.It has been proved that the system is stable and reliable,and that the file system can be read or written by a Windows system.更多还原
