Advancing type magnetic suspension demonstration system and floater static suspension and marching control method

Abstract

The invention relates to an advancing type magnetic suspension demonstration system and a floater static suspension and advancing control method. The demonstration system comprises a floater, a permanent magnet track, magnetism adjusting coils, a magnetic field intensity sensor, control units, a master control unit and the like. The permanent magnet track is of a double-track structure formed by splicing strip-shaped magnetic steel in the length direction, and the magnetism adjusting coils are arranged on the inner side of each track of the permanent magnet track in a row in the length direction. Each control unit comprises a single chip microcomputer, a network communication module, a driving circuit and the like; and the master control unit is electrically connected with all the control units through a network and is used for controlling the floater to advance and statically suspend above the permanent magnet track. The system is simple in structure, the demonstration mode is visual and clear, supporting in the gravity direction and positioning in the lateral direction can be completed at the same time only by means of a plane magnetic field with gravity as the normal, and suspension operation of the floater along the track can be achieved through a single-plane invisible track. Therefore, the suspension effect provided by magnetic suspension can be observed more visually.

Description

technical field [0001] The invention relates to a magnetic levitation device, in particular to a traveling magnetic levitation demonstration system and a static levitation and traveling control method of a float. Background technique [0002] The floats in the existing maglev products or demonstration systems are basically stationary or freely rotating around the Z-axis. As far as the actual situation is concerned, it is difficult for the maglev system to achieve the lifting or pulling magnetic field of the stator, the levitation magnetic field of the float and the floating magnetic field. The complete coincidence and balance of one's own center of gravity. The effect of its unbalance is generally reflected in the uncontrolled degree of freedom of the float, that is, the torque on its Z axis is out of control. In view of this, any small disturbance on the Z-axis torque will show an unstable state because the float does not have any damping in this direction, which is manife...
