Abstract
A break detection device includes a sensor, an abnormal variation detection unit (), a storage unit (), an arithmetic unit (), and a break determination unit (). The arithmetic unit () increases a determination score when the abnormal variation detection unit () detects occurrence of an abnormal variation when a car () passes a position stored in the storage unit (). The arithmetic unit () decreases the determination score when the abnormal variation detection unit () does not detect the occurrence of the abnormal variation when the car () passes the position. The break determination unit () determines whether or not a broken portion is present in a rope on the basis of the determination score.
