Abstract (en)

[origin: EP2583928A1] In order to reliably detect open-door movement at a shorter movement distance (at an earlier point in time), thereby enhancing safety, and maintaining operational efficiency, an elevator system equipped with an unintended car movement protection, which assesses open-door movement and stops the car if the car moves up or down relative to the landing floor with the car doors and/or landing doors being opened, and is further provided with: a car door switch (43) that detects when car doors are opened and a landing door switch (41) that detects when landing doors are opened, a detection device (21) that detects the velocity and movement distance of the car, a position sensor (30) that detects the reference floor position at each storey, and a safety controller (1) that determines an open-door movement abnormality on the basis of the results detected by the detection device (21) and the position sensor (30), using a car-speed abnormality determination threshold value that is defined to the car position.
