Title:
ELEVATOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/073848
Kind Code:
A1
Abstract:
This elevator control device comprises: a cooling fan 24; a component 21 to be cooled that is used to control the drive of a hoist machine 4 and is cooled by a cooling fan 23; a temperature sensor 25 that measures the temperature of the component 21 to be cooled; and a control device 30 that controls the entire elevator device. The control device 30 is equipped with a control unit 31 and a cooling effect diagnostic unit 32. The control unit 31 controls the drive of the hoist machine 4, and performs normal operation and efficient heat generation operation in which the component 21 to be cooled is heated to a temperature higher than the temperature during normal operation for diagnostic purposes. The cooling effect diagnostic unit 32 diagnoses the cooling effect of the component 21 to be cooled on the basis of the temperature measurement values obtained from the temperature sensor 25 during the efficient heat generation operation.
