Earthquake precursor Schumann resonance vertical electric field receiving device

The invention discloses an earthquake precursor Schumann resonance vertical electric field receiving device. The device includes a T-shaped antenna assembly, a signal conditioning module, an analog-to-digital conversion module and an analysis host. The signal conditioning module comprises a preamplifier circuit unit, a 50Hz trap wave circuit unit and a low-pass filtering circuit unit. The T-shaped antenna assembly is connected with an input end of the preamplifier circuit unit, an output end of which is connected with an input end of the 50Hz trap wave circuit unit. An output end of the 50Hz trap wave circuit unit is connected with an input end of the low-pass filtering circuit unit, an output end of which is connected with an input end of the analog-to-digital conversion module. An output end of the analog-to-digital conversion module is connected with the analysis host. The T-shaped antenna assembly and the signal conditioning module are simplified, and thus the device is easy to implement. Enormous calculation is not necessary, a proper analog signal can be obtained through three steps, and finally Schumann resonance with low noise and high quality can be seen in an obtained power spectrum.
