Abstract:
    The invention relates to the ground electric potential dynamic observation system mainly used for the Earth physics measurement especially for the ground electric potential or high-density electrical method dynamic or static observation. It is consist of the superior machine, the switch controller, the network electric cable and the electrode conversion switch. Each one measuring line can be set with one to N electrode conversion switches which are connected to the switch controller by the network electric cable in the mode of the string and the switch controller can connect 1 to N network electric cables. The superior machine controls the close and open of the electrode conversion switch in a random measuring line of the 1 to N lines. Also it can detect the inputting position of the electrode accurately and display the electrode conversion switch state dynamically. It needs to provide power supply for the electrode conversion switch and don
