Abstract

Abstract. Geoelectrical resistivity is an excellent method to investigate the structural composition of shallow subsurfaces. However, existing commercial equipment is typically expensive and often requires proprietary accessories and software to provide full system functionality. The objective of this study was to develop a multichannel, modular, automated, and programmable geo-resistivity meter capable of user customization and programming. To this end, a conceptual prototype was built based on free software and open hardware technologies as a low-cost alternative to commercial equipment while maintaining the accuracy and quality of the data at the same level. The prototype was based on electrode multiplexing to make the switching process more efficient by reducing cabling complexity, whereas synchronous demodulation for signal detection was employed, providing strong rejection of spurious electrical noise, typical of urban areas where such equipment is frequently used. The results demonstrate the feasibility of this project and an important academic contribution to open-source instrumental research.

用于浅层地下探测的自动可编程电阻率计的设计与施工

摘要地电阻率是研究浅亚表层结构组成的一种很好的方法。然而，现有的商业设备通常是昂贵的，并且通常需要专有的附件和软件来提供完整的系统功能。本研究的目的是开发一种能够进行用户定制和编程的多通道、模块化、自动化和可编程地电阻率计。为此，在自由软件和开放硬件技术的基础上建立了一个概念原型，作为商业设备的低成本替代品，同时将数据的准确性和质量保持在同一水平。该原型基于电极多路复用，通过降低布线复杂性来提高切换过程的效率，而采用同步解调进行信号检测，提供了对杂散电噪声的强大抑制，这是经常使用此类设备的城市地区的典型情况。研究结果证明了该项目的可行性，并为开源工具研究做出了重要的学术贡献。

期刊介绍： Geoscientific Instrumentation, Methods and Data Systems (GI) is an open-access interdisciplinary electronic journal for swift publication of original articles and short communications in the area of geoscientific instruments. It covers three main areas: (i) atmospheric and geospace sciences, (ii) earth science, and (iii) ocean science. A unique feature of the journal is the emphasis on synergy between science and technology that facilitates advances in GI. These advances include but are not limited to the following: concepts, design, and description of instrumentation and data systems; retrieval techniques of scientific products from measurements; calibration and data quality assessment; uncertainty in measurements; newly developed and planned research platforms and community instrumentation capabilities; major national and international field campaigns and observational research programs; new observational strategies to address societal needs in areas such as monitoring climate change and preventing natural disasters; networking of instruments for enhancing high temporal and spatial resolution of observations. GI has an innovative two-stage publication process involving the scientific discussion forum Geoscientific Instrumentation, Methods and Data Systems Discussions (GID), which has been designed to do the following: foster scientific discussion; maximize the effectiveness and transparency of scientific quality assurance; enable rapid publication; make scientific publications freely accessible.
