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 of operating a safety net system of an elevator system is provided. The method includes installing a sensor in an elevator pit of the elevator system and executing a learning phase of the sensor to verify successful installation of the sensor. The executing of the learning phase includes causing the sensor to sense physical characteristics of a portion of the elevator pit when the elevator pit is known to have certain physical characteristics to generate a background reading, comparing the background reading against a reading associated with known physical characteristics of the portion of the elevator pit and verifying the successful installation of the sensor based on results of the comparing.

Abstract: Methods and systems for determining elevator car locations are provided. Aspects includes a sensor affixed to a moving component of an elevator system, wherein the sensor is operated by a controller and wherein the controller is configured to determine that the elevator car is in motion based at least in part on the sensor. A direction of the elevator car is determined while the elevator car is in motion based at least in part on the sensor. Sensor data associated with the elevator car is collected while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion. Elevator car travel data is accessed from a travel time profile associated with the elevator car and the travel time is compared to the elevator car travel data to determine a location of the elevator car in a hoistway.

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: A brake assembly for an elevator system is provided and includes a guide rail configured to guide movement of an elevator car. Also included is a safety brake operatively coupled to the elevator car and having a brake surface configured to frictionally engage the guide rail. Further included is a safety brake actuation mechanism operatively coupled to the safety brake and configured to actuate the safety brake to a braking position. The mechanism includes a first sensing device disposed on a first side of the guide rail to detect a first condition reading of the elevator car relative to the guide rail. The mechanism also includes a second sensing device disposed on a second, opposite side of the guide rail to detect a second condition reading of the elevator car relative to the guide rail, the first and second condition readings collectively analyzed to determine an overall condition reading.
