Abstract: A method of calibrating a monitoring device (20) for monitoring movement of a movable component (2, 12, 19) of an elevator system (2) comprises detecting (120) a travel time (Δtk) between a starting time (tk) and a stopping time (t′k) as well as acceleration (a(t)) of at least one movement of the movable component (2, 12, 19); determining (130, 140) a travel distance of the movable component (2, 12, 19) by integrating the detected acceleration (a(t)) twice with respect to the detected travel time (Δtk); correlating (150) the determined travel distance (sk) with the detected travel time (Δtk) to form a pair of travel time and travel distance; and storing (160) the pair of travel time and travel distance (Δtk,sk) as part of a travel profile (34).

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.
