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.
