Abstract:

Based on the two time-difference induced polarization method, a tunnelgushing detector design was proposed. A specific realization of the receive system design in the PC+MCU mode was described. A series of optimization technology in IP-voltage collection was also discussed. Finally, a measurement result of the detector based on this design was shown.
