High-efficiency data acquisition system adopting mine direct-current electrical method and method of high-efficiency data acquisition system

The invention relates to a high-efficiency data acquisition system adopting a mine direct-current electrical method and a method of the high-efficiency data acquisition system, and is applied to judging a water-containing area in a coal mine underground roadway; the high-efficiency data acquisition system comprises a power supply, a measurement host, a large-cable interface converter, a large measurement cable, an electrode contact and a copper electrode; the measurement host can be switched on by distributing the large measurement cable and plugging the electrode contact; the working efficiency for sounding and detecting in advance in a roadway is high; the signal to noise ratio is high; the measurement data quality can be artificially controlled; a heavy wire frame is unnecessary to bear to be used for contracting and releasing a measurement conductor wire in a reciprocating manner in the event of changing electrodes; and electrode changing can be carried out only by carrying a measurement electrode and a geological hammer.
