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.

A method of calibrating a monitoring device () for monitoring movement of a movable component () of an elevator system () comprises detecting () a travel time (Δt) between a starting time (t) and a stopping time (t') as well as acceleration (a(t)) of at least one movement of the movable component (); determining () a travel distance of the movable component () by integrating the detected acceleration (a(t)) twice with respect to the detected travel time (Δt); correlating () the determined travel distance (s) with the detected travel time (Δt) to form a pair of travel time and travel distance; and storing () the pair of travel time and travel distance (Δt,s) as part of a travel profile ().

Device and method for monitoring an elevator system

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.
