Magnetic levitation air suspension height adjusting system and method

The invention belongs to the technical field of magnetic levitation vehicles, and particularly relates to a magnetic levitation air suspension height adjusting system and method. Each suspension frameis connected with a sliding table through two air springs; the suspension frame of each carriage is divided into a front part, a middle part and a rear part; two sensor induction plates are arrangedon the middle suspension frame, two sensor induction plates are arranged on the front suspension frame or the rear suspension frame, and a height sensor corresponding to the sensor induction plates isarranged on the sliding table. The first suspension frame and the fifth suspension frame are grouped, the second suspension frame, the third suspension frame and the fourth suspension frame are grouped, four-point control is formed through the height sensors on the second suspension frame and the fifth suspension frame, the height of the air springs is adjusted and controlled, then the floor surface of each carriage is lev
