Abstract

Induced polarization method is one of common methods for electrical prospecting of geophysical. The paper is to analyses and research application of embedded technology for induced polarization instrument and design multifunctional transceiver instrument. The paper is to realize hardware part of induced polarization instrument by regarding ARM processor as hardware core by combination of current intelligent power module (IPM), induced polarization analog signal processing and 24-digit △-∑ high-precision A/D conversion chip (CS5532), etc. It can transplant embedded operation system (uClinux) on embedded ARM processor and formulate drive program which matches hardware circuit and application program to fulfils various functions including data acquisition, data processing & display, data storage & transmission required by induced polarization instrument under uClinux system management.
