摘要
介绍一种高精度磁力计的数据采集模块,给出三路AD高精度数据采集系统的关键器件选型、数据采集系统设计、接口电路设计、软件设计以及系统性能分析。系统采用高精度∑-△ADC芯片AD7712,实现对磁力计探头信号的高精度采集,并将数据通过串口发送到上位机进行分析处理,得到符合磁力计设计指标的数据。
In this paper, module design of data acquisition of high precise magnetometer is introduced. The key component selection ,design of data acquisition system, interface circuit and system performance analysis of triplexer high precise data acquisition were given. In this system ,hign precise ∑-△ADC chip AD7712 was selected ,to realize high precise data acquisition of magne-tometer probe. The data were send to computer throught serial port and they were analysed and processed. Finally the data which meet the requirement of the design were given.
