Abstract
The invention discloses an underground miner search and rescue system based on magnetic resonance and an underground miner search and rescue method thereof. The system is composed of a ground search and rescue end and an underground miner wearing induction end. The ground search and rescue end transmits a magnetic field of the specific frequency through an induction coil. The underground miner wearing induction end is internally provided with the induction coil, and the inherent frequency is the same with the frequency of the magnetic field generated by the ground search and rescue end. When the induction coil worn by a miner is in the magnetic field transmitted by the ground search and rescue end, magnetic coupling resonance is generated so that signals are simultaneously fed back to the ground search and rescue end and the underground miner wearing end to assist search and rescue. A complex signal processing algorithm is not required, and the system composition is simple. The magnetic field carries relatively high energy and is favorable for penetrating through a thick geological layer, and simple information can be transmitted to the miner in search and rescue on the basis of the principle of magnetic coupling resonance so that the insufficiency that the conventional search and rescue device cannot transmit information to the searched and rescued persons can be compensated.
