Abstract

The invention discloses an emergency stop control device, a magnetic levitation system and an emergency stop control method of the magnetic levitation system. The device comprises an emergency stop switch and a discharge control unit, wherein the emergency stop switch is used for enabling a normally-closed switch of the emergency stop switch to be in an off state and a normally-open switch of theemergency stop switch to be in an on state under the condition that an emergency stop instruction for powering off the magnetic levitation system is received so as to achieve emergency stop of the magnetic levitation system; and the discharge control unit is used for maintaining the outage of the magnetic levitation system by taking the discharge capacity of the discharge part of the magnetic levitation system as a power supply under the condition that the discharge part of the magnetic levitation system does not complete discharge after the magnetic levitation system is suddenly stopped untilthe discharge part of the magnetic levitation system completes discharge. According to the scheme, the problem that the reliability of a magnetic levitation centrifugal machine system is affected bythe reset of the emergency stop switch before the magnetic levitation centrifugal machine system is completely powered off can be solved, and the effect of improving the reliability of the magnetic levitation centrifugal machine system is achieved.

Description

technical field [0001] The invention belongs to the technical field of magnetic levitation, and in particular relates to an emergency stop control device, a magnetic levitation system and an emergency stop control method thereof, in particular to a magnetic levitation system control circuit, a magnetic levitation system and an emergency stop control method thereof. Background technique [0002] In the magnetic levitation centrifuge system, due to the large energy storage capacitor on the DC bus of the inverter, when the unit is shut down in an emergency, the system needs a certain discharge time to completely cut off the power of the unit. If the emergency stop switch is reset before the unit is completely powered off If the unit is powered on again, the controller of the magnetic levitation centrifuge system cannot be reliably powered off and reset because it has not been completely powered off. [0003] The above content is only used to assist in understanding the technica...
