基于单片机的高精度海量数据采集与存储系统

High-accuracy mass data acquisition and storage system based on single-chip microcomputer

为满足在某些恶劣实验环境条件下数据的高精度采集、海量存储以便事后分析的需要,设计出了以MSP430F1611单片机为主控单元,采用16位高精度A/D转换芯片ADS1146实现数据采集;利用大容量TF存储卡实现数据的海量存储,并通过并口转USB芯片及相应的上位机软件实现数据上传以便进行事后分析。目前,该数据采集存储系统已在相关实验项目中得到应用,并获得了良好稳定的实验结果。

To meet high-accuracy data collection, mass storage and later analysis under some bad conditions of experi- ment, the main control unit with MSP430F1611 was designed. 16-bit high-accuracy A/D conversion chip ADS1146 is adopted to realize data acquisition. The large capacity TF memory card is used to achieve data mass storage. By making use of the USB- parallel chip FT245 and corresponding host computer software, the data upload was realized, so as to analyze the later data. This data acquisition and storage system has already been applied to some experiments and achieved stable experiment results.
