Internet-of-things-based four-dimensional high-density electrical instrument for geophysical prospecting

Abstract. The high-density electrical method is a primary used in shallow geophysical prospecting. Due to the rapid industrial development that has taken place recent years, function and performance of instruments have been considerably improved several aspects. However, most currently available on market still exhibit some shortcomings, such as being bulky, heavy, limited their data acquisition accuracy, difficult connect Internet for remote monitoring. To address these problems, this study developed new multifunctional four-dimensional (4D) instrument based wireless communication technology. system small lightweight, includes an integrated transceiver, high capable real-time control. In study, hardware circuit was designed. Arm all-in-one (AIO) LJD-eWinV5-ST7 with 154.4 cm × 87 cm, 800 480 high-brightness wide-temperature-range display host computer, which advantages size, low power consumption, abundant resources. things (IoT) technology incorporated system, 4G module employed provide control monitoring cloud platform. Tests showed stable convenient use can meet requirements field
