Research and design of 3-D electronic resistivity embedded data acquisition sub-station system based on ARM7

提出了一种基于ARM7的嵌入式三维电阻率采集子站设计方法,采用24位A/D转换器(ADS1258)和ARM7微处理器(LPC2378),使三维电阻率法数据采集系统具有体积小、功耗低、成本低、精度高等特点,同时实现μC/OSⅡ操作系统在ARM的移植,为数据采集的实时性提供可能。

This article proposed a design method for 3-D electronic resistivity embedded data acquisition sub-station system based on ARM7,by using A/D converter（ADS1258）with 24 bits and the ARM7 microprocessor（LPC2378）,the 3-D resistivity geophysical instrument is small in volume,low in the cost and power consumption and high in precision.The μC/OS-Ⅱoperating system is embeded in ARM and provides the possibility for real time data acquisition.
