Document Type and Number:
Japanese Patent JP7115396
Kind Code:
B2
Abstract:
To provide an elevator control device for detecting a failure of an exhaust fan by a smaller number of components.SOLUTION: This elevator control device comprises: a fan driving unit that outputs a driving command for simultaneously driving an exhaust fan and a suction fan; and a failed fan determination unit that determines the failure of the exhaust fan if rotation of the exhaust fan is not detected when the fan driving unit drives the exhaust and suction fans by a driving command set such that the exhaust fan does not corotate by means of a wind force from the suction fan. By this configuration, the failure of the exhaust fan is detected by a smaller number of components.SELECTED DRAWING: Figure 2
