摘要
为了满足高精度地磁数据采集的需要,本文提出一种在磁通门磁传感器基础上,使用ADS1282搭配C8051F340单片机搭建四通道32位高精度地磁场数据采集板的设计方法。与现有地磁采集器相比,该方法设计的采集板具有低噪声、大动态范围、低功耗和多通道等优势。经实验室和野外测试,系统工作稳定,采集到的数据质量高,并解决了现有设备不能在野外长期数据采集的不足。
To measure geomagnetic data precisely, a measure system is described which is based on fluxgate sensor. This fourchannel and 32-bit precision system which is constituted of ADC and MCU program is stable and can be used in long-term outdoors measure or indoor science research. Compared with the existing geomagnetic acquisition, the acquisition board designed by this measure has advantages of low noise, large dynamic range, low-power and multi-channel.Thoughout laboratory and field testing, the data collected by this measure have a high quality.
