The invention relates to the technical field of magnetic levitation traction control, in particular to a high-speed magnetic levitation vehicle positioning speed measurement position identification method and system. The method comprises the steps that an antenna unit is arranged on the high-speed magnetic levitation vehicle, and the antenna unit comprises a transmitting antenna and a receiving antenna; a high-frequency current is introduced into the transmitting antenna to generate a magnetic field, an induced current is generated in the suspension coil on the same side as the transmitting antenna along with the operation of the aircraft, and the induced current flows into the suspension coil on the opposite side on the same side as the receiving antenna through a hinge line, so that the suspension coil on the opposite side generates an induced electromotive force in the receiving antenna; and determining the relative position information of the high-speed magnetic levitation vehicle according to the generated induced electromotive force. Therefore, the transmitting antenna can be coupled with the suspension coil, and the voltage signal changing along with the position can be sensed in the receiving antenna, so that angle extraction is carried out by utilizing the voltage signal, and finally, the positioning and speed measurement of the high-speed magnetic suspension aircraft are realized.
