Magnetic levitation bearing monitoring method, device and host, and computer readable storage medium

Abstract

The invention discloses a magnetic levitation bearing monitoring method, device and host, and a computer readable storage medium. The magnetic levitation bearing monitoring method comprises the stepsthat a control chip receives a real-time displacement signal output by a displacement sensor, wherein the real-time displacement signal belongs to a magnetic levitation rotor; the control chip sends the real-time displacement signal to the monitoring host; and the monitoring host judges whether the magnetic levitation rotor is in an abnormal state or not according to the real-time displacement signal, and if it is determined that the magnetic levitation rotor is in the abnormal state, a first control signal is output to a frequency converter. The invention further provides the monitoring device, the monitoring host and the computer readable storage medium for achieving the method. The computational load of the control chip can be reduced, and the efficiency of a magnetic levitation monitoring system is improved.

Description

technical field [0001] The invention relates to the field of bearing control, in particular to a magnetic suspension bearing monitoring method, a device for realizing the method, a magnetic suspension monitoring host applying the method, and a computer-readable storage medium. Background technique [0002] Because the magnetic levitation centrifuge has the advantages of high operating speed and maintenance-free, it is widely used in various electrical products. Therefore, the demand for the magnetic levitation centrifuge series products in the market is also increasing. Generally, a magnetic levitation centrifuge has a magnetic levitation bearing on which the rotor of the centrifuge is supported. After the magnetic suspension bearing is energized, the magnetic suspension rotor is suspended on the magnetic suspension bearing, and the magnetic suspension rotor does not directly contact the magnetic suspension bearing when rotating, and the friction force is very small, so the ...

Problems solved by technology

[0008] But, because the control chip 11 is usually a small chip, the computing power is limited, and the amount of calculation for judging the running state of the magnetic levitation rotor 12 is very large, and these calculations will take up a large amount of memory space of the control chip 11. In addition, the control chip 11 The program is run in serial mode, which takes a lot of running time, which will greatly reduce the control efficiency of the maglev centrifuge
