A New Method for High-Precision Geoelectric Data Acquisition Based on CS5372

This paper introduces a new method for high-precision geoelectric data acquisition based on CS5372 to research and design an A/D conversion controller , a module converting the serial data to parallel one, a resampling FIR digital filter using Matlab and DSP Bulider, a NIOS II Soft IP Core integrated by Quartus II and a PC software designed with LabVIEW. Under the application of equipments mentioned above, Cyclone chip, which replaces expensive CS5376, can be used to realize the acquisition of the high-precision geoelectric data. As the result shown, the new method can greatly improve the cost-effectiveness of high-precision geoelectric data acquisition devices and also can integrate the digital parts of geoelectric data acquisition devices into a chip, which also provide an effective way to solve problems under the complex geoelectric conditions.
