[0036] It should be noted that the power supply track detection device of the utility model is used in the field of medium and low speed magnetic levitation track detection. The special cross-sectional shape of the F-type track 13 of the medium and low speed magnetic levitation is different from the traditional wheel-rail "I"-shaped track.
