Self-powered mine identity radio frequency identification device and mine car

The invention discloses a self-powered mine identity radio frequency identification device and a mine car. The mine identity radio frequency identification device comprises an even number of permanentmagnets, and a coil, a power supply management circuit, a rechargeable battery and an identity identification and radio frequency circuit which are electrically connected, each permanent magnet is uniformly fixed on the same circumference of a wheel according to a rule of alternating N/S and S/N polarities, and the power supply management circuit rectifies and converts the alternating current generated by the coil, outputs a stable direct current power supply to charge the rechargeable battery, and supplies power to the identity identification and radio frequency circuit; and when no electricenergy is generated in the coil, the power supply management circuit extracts the electric energy of the rechargeable battery and outputs a stable direct-current power supply to supply power to the identity identification and
