Abstract
In an elevator control apparatus, the presence/absence of an abnormality in an elevator is monitored by an abnormality monitoring portion. The abnormality monitoring portion makes a determination on the presence/absence of an abnormality in the elevator based on information from a sensor, and outputs a signal for stopping a car upon detecting an abnormality. The history of information on the result of determination by the abnormality monitoring portion is recorded in a history information recording portion.
