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: 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.
