Stratum outcrop and rock mass spectrum parameter measuring device and method

The invention discloses a stratum outcrop and rock mass spectrum parameter measuring device and method, a transmitting end of the measuring device generates an excitation signal by a DDS module, an observer determines a constant-voltage or constant-current mode for observation, the signal forms a constant high-voltage signal source or a constant-current output current source signal after passing through the constant-voltage or constant-current module, and the constant high-voltage signal source or the constant-current output current source signal is transmitted to the DDS module. The signals are output to the ground by a grounding electrode A and a grounding electrode B, and a stable observation signal field source is established; a receiving end obtains geoelectric response information under excitation of each frequency signal through grounding electrodes M and N, the geoelectric response information is processed and then sent to an MCU to be displayed and stored, frequency spectrum parameters of stratums or
