Abstract: A system and method determine the position of an elevator car movably arranged in an elevator shaft of an elevator system. The system has a 3D sensor, an evaluation unit communicating with the sensor, and a marking element. The sensor has a plurality of sensor cells and the evaluation unit uses measurement data received from the sensor to determine a distance from each sensor cell to a part of a detected object. The sensor is arranged such that in a normal mode of the system it detects the marking element as the object. The evaluation unit determines the position of the elevator car in the elevator shaft based on distances from sensor cells to the detected part of the object, continuously performs a test as to whether the sensor detects the marking element and brings the system into an error mode as soon as the test is negative.

Abstract: A system determines the position of an elevator car movable in an elevator installation shaft. A transmitter emits modulated electromagnetic radiation with a first modulation frequency as a first output signal, a sensor cell receives electromagnetic radiation reflected by a detected object as an original measurement signal, and an evaluation unit, communicating with the transmitter and the sensor cell, delays the original measurement signal thus generating a delayed measurement signal, determines a first phase offset between the original measurement signal and the first output signal, determines a second phase offset between the delayed measurement signal and the first output signal, selects either the first phase offset or the second phase offset based upon a selection condition to determine a position of the elevator car within a portion of the elevator shaft, and determines the elevator car position based upon the elevator shaft portion and the position within the portion.

Abstract: A system and a method for determining the position of an elevator car, movably arranged in an elevator shaft of an elevator unit, use a 3D sensor, an evaluation unit in communication with the sensor, and a marking element actively emitting electromagnetic radiation. The sensor has a plurality of sensor cells and the evaluation unit uses measurement data received from the sensor to determine a distance from each sensor cell to a part of an object detected by the sensor. The sensor is arranged to detect the marking element and a region around the marking element as the object. The evaluation unit determines those sensor cells that detect the marking element and determines the position of the elevator car based on the determined distances to the detected object of those sensor cells and/or of sensor cells that are arranged in a region adjacent to those sensor cells.
