In order to promote the integration of resistivity/induced polarization sounding arrays and upgrade traditional centralized high-density electrical method instruments, we optimized the “Electrical Exploration Electrode Array Line Borrowing Remote Control” (invention patent ZL.201711013579.5, inventors: Liang Binghe and Ge Weizhong). This system not only reduces the number of wiring electrodes for field exploration, but also breaks through the exploration depth, reaching a detection depth of 600-800 meters.
