The invention provides a non-contact magnetic-levitation train positioning device and method and a magnetic-levitation train. The non-contact magnetic-levitation train positioning device comprises a transmitting antenna, a plurality of pairs of induction loop lines and a signal processing unit. The transmitting antenna is arranged on a body of the magnetic-levitation train. The induction loop lines are laid on a rail. When the transmitting antenna is connected with high-frequency alternating current, an alternating magnetic field is formed surrounding the transmitting antenna and used as an excitation source of the alternating magnetic field. The induction loop lines are used for generating induction voltage signals when the transmitting antenna moves along the induction loop lines. The signal processing unit is used for obtaining the position information of the magnetic-levitation train according to the induction voltage signals sent by the induction loop lines. According to the non-contact magnetic-levitation train positioning device, the transmitting antenna is arranged on the train, the induction loop lines are laid on the rail, and the position information can be transmitted without additional train-ground communication equipment, so that the structure of a whole train system is simplified, the system construction cost is lowered, and the reliability of the system is improved.
