Intelligent acquisition device and method for multi-exploration geophysical field signal

The invention discloses an intelligent acquisition device and method for multi-exploration geophysical field signals, and relates to the technical field of geophysical exploration. The method comprises the following steps that: a processor controls a working mode switching circuit to send signals to the input end of a designated signal conditioning circuit; the working mode switching circuit switches the signals to the input end of an analog-digital converter; the signal conditioning circuit processes the received signals and transmits to the analog-digital converter; the analog-digital converter processes the signals and sends to the processor; and the processor is connected to a communication module. The intelligent acquisition device can take both active sources and passive sources intoconsideration. The method has the advantages that the intelligent acquisition device can acquire the same or different physical field signals in parallel, so that the detection method is diversified,and the exploration const
