Design of self-potential measure system based on acquisition station

摘要

Since the 20th century, the self-potential method has been widely used in many fields, including landslides, environmental issues, groundwater and geothermal exploration and so on. However, the repeated observations of Self- potential is poor and high noise interference characteristics, greatly reducing the scope of application of the self-potential method. The hardware and software practical developing procedures of Self-Potential measure system based on acquisition station are introduced in this essay. In view of Self-Potential signal essential feature and the need of exploration technology, this essay offers an alteration to the traditional measuring technique of digital multi-tester to the computer program control technology. The measuring technique is parallel time series. On the system of LabWindows/CVI, users may adjust its function and scale by modifying the software.
