Abstract

Detection device for a lift with a cabin with at least one cabin door, which is designed to carry out an opening movement and a closing movement when the cabin stops at a floor, to determine the floor when the lift cabin stops at a floor. The detection device has at least one accelerometer to detect the vibration of the cabin door during the opening movement and/or the closing movement. The detection device has an evaluation device, which is designed to create a vibration profile from the detection of the vibration during an opening movement and/or closing movement, and during a learning phase to create and store a reference vibration profile for each of at least two floors from one or more vibration profiles, and outside the learning phase to compare the currently recorded vibration profile with the existing reference vibration profiles, and to determine the reference vibration profile with the best match to the currently recorded vibration profile from the comparison, and to determine the relevant floor from this.
