The invention discloses a converter, which can be used for direct current prospecting. The converter is characterized in that two communication interfaces used for transmitting electric signals are provided; a signal processing module is connected between the two communication interfaces, and is used to receive power supply signals input by one of the communication interfaces, and is used to output the power supply signals to the other communication interface; a driving circuit module connected with the signal processing module, and is used to transmit the driving current to an electric switch according to the electric signals; and an electric switch module is connected with the driving circuit module, and is connected with an electrode. During the exploration and survey, the converter can be used for the sequential connection to transmit the power supply signals, and then the power supply of the electrode can be realized. By comparing with the prior art of supplying the electrode with the power by the single channel of the transmission host, the converter is advantageous in that the multi-stage connection can be realized, the electrode arrangement range can be enlarged, and the exploration and survey range can be enlarged.
Description
technical field [0001] The invention relates to the technical field of DC prospecting, in particular to a converter. Background technique [0002] The direct current method is a geophysical exploration method that uses artificially established stable direct current electric fields and observes the electric field distribution differences caused by different geological bodies to study geological structures, search for mineral resources, and solve engineering geological problems. The electric field differences are mainly reflected in Resistivity and polarizability of geological bodies. [0003] During on-site measurement, electrodes are arranged in the measurement area, and a DC electric field is established by energizing the electrodes. The converter is the link between the transmitter host and the electrodes. The transmitter host sends a power supply control signal to the converter, and the converter controls which electrodes are connected according to the power supply signa...
