Abstract: According to an aspect, a method includes collecting a calibration set of vibration data for an elevator car at a plurality of landings in a hoistway. One or more characteristic signatures are determined at each of the landings based on the calibration set of vibration data. An analysis set of vibration data is collected for the elevator car. A position of the elevator car is identified in the hoistway based on comparing one or more features of the analysis set of vibration data to the one or more characteristic signatures. An indicator of the position of the elevator car in the hoistway is output.

Abstract: A monitoring device (20, 22), which is configured for monitoring movement of at least one component (6, 12) of an elevator system (2), includes an acceleration sensor (24) and a controller (26). The acceleration sensor (24) is configured for detecting accelerations (g, g′) of the at least one component (6, 12) and providing a corresponding acceleration signal (28, 30). The controller (26) is configured for determining peaks (28a, 28b, 30a, 30b) having positive or negative signs in the detected acceleration signal (28, 30); determining the signs of the detected peaks (28a, 28b, 30a, 30b); and determining that the moving direction of the at least one component (6, 12) has changed when two subsequent peaks (28a, 28b, 30a, 30b) of the acceleration signal (28, 30) having the same sign are detected.

Abstract: An illustrative example elevator sensor device includes at least one sensor supported on a door of an elevator car. The sensor provides an output including an indication of at least movement of the door along at least one axis and movement of the elevator car along at least one axis. A processor associated with the at least one sensor receives the output and determines at least one characteristic of the movement of the door based on the indication of the movement of the door. The processor also determines a location of the elevator car where the movement of the door occurs based on the indication of movement of the elevator car.

Abstract: According to an aspect, a method includes monitoring a plurality of vibration data by a vibration monitoring beacon and determining that the vibration monitoring beacon has been installed at a service location based on detecting an installation characteristic signature in the vibration data. The vibration monitoring beacon can transition into a learning mode based on determining that the vibration monitoring beacon has been installed at the service location. The method can also include monitoring for a learning mode termination event and transitioning the vibration monitoring beacon from the learning mode to a normal operation mode based on detecting the learning mode termination event.

Abstract: A method for monitoring thresholds for performance attributes in an elevator system is provided. Aspects includes collecting, by a sensor affixed to an elevator car, sensor data associated with the elevator system wherein the sensor data comprises one or more performance attribute values for a set of performance attributes of the elevator system. Obtaining a threshold profile associated with the elevator system, wherein the threshold profile comprises thresholds for each performance attribute in the set of performance attributes of the elevator system. Comparing the one or more performance attribute values to corresponding thresholds for the set of performance attributes and transmitting an alert for any of the one or more performance attribute values exceeding the corresponding thresholds for the set of performance attributes.
