Abstract (en)
[origin: EP3438033A1] Provided is an elevator system capable of determining availability of opening/closing of a car door after determining whether a car is located in a door zone even if a position detection device provided on the car breaks down. An elevator system (100) includes a plate to be detected (11) provided in a hoistway (4), a car position detection device (10) provided on the car (1) and which detects the plate to be detected (11), a car moving amount measurement device (7 or 15) that measures a moving amount of the car, and a control device (20) that controls the aforementioned plate and devices, the control device includes a door zone detection unit (12) that detects a door zone that is an openable/closable region of a door of the car by the car position detection device and a car position calculation unit (16) that calculates a position of the car by the car moving amount measurement device, and determines whether the car is in the door zone on the basis of the position of the car calculated in the car position calculation unit when the car position detection device is determined to have broken down.
