英文摘要：

Appearance and application of multi-electrode source induced polarization is a breakthrough of induced polarization method. However, forecasting instrument is a bottleneck of this method. Using MSP430-based inverters, rectifiers and an inverter control module to implement 4-way controllable rectifier output, using FPGA to achieve the voltage and current 4-channel synchronous acquisition and signal transmission, designing automatic range switching signal denoising module and combining software with hardware, a geological prediction device was designed, and its signal acquisition and operational stability indoor were tested qualitatively and quantitatively. The results show that the device meets the requirements of engineering detection accuracy, practicality and feasibility.
