Design of Data Acquisition System for Geo-Electrical Resistivity Meter Based on ADS1256
摘要
Abstract
The purpose of seismic earth resistivity monitoring is to observe the change of geo-electrical resistivity in a specific area,which requires high measurement accuracy.The data acquisition system of geo-electrical resistivity meter is based on the 24 bit analog-to-digital converter of ADS1256.It has the characteristics of high precision,low noise,large dynamic and strong anti-interference ability.The labora-tory test results show that its voltage resolution reaches 10 μV,peak to peak noise is less than 7 μV and the dynamic range reaches 120 dB.The main technical performance indicators of the data acquisition system meet the needs of seismic geo-electrical resistivity moni-toring and prediction research.It can also be applied to other fields requiring high-precision,low-noise DC voltage measurement.关键词
