NOVELTY - The utility model belongs to the technical field of geophysical logging, relating to an underground time domain or frequency domain multi-component electromagnetic remote detection instrument. An underground time domain or frequency domain multi-component electromagnetic measuring instrument based on graphene electromagnetic shielding, comprising: time domain or frequency domain multi-component electromagnetic emitting module, multi-level array time domain or frequency domain multi-component electromagnetic signal receiving module, multi-channel analogue-to-digital conversion module and three-component optical fibre inertial navigation positioning orientation module; the time domain or frequency domain multi-component electromagnetic signal emitting module is used for generating three-component excitation magnetic field, the multi-level array time domain or frequency domain multi-component electromagnetic signal receiving module is used for receiving the time domain or frequency domain three-component magnetic field signal and single component or three-component electric field signal. The utility model can greatly reduce the strong interference of the emitting signal to the instrument electronic device and the circuit board module, reduce the interference noise directly to coupling instrument signal receiving end, improve the signal-to-noise ratio and detection sensitivity of the instrument.
