    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: An elevator system includes a car door and a sensor module. The car door is movable relative to an elevator car by a drive mechanism. The sensor module includes a first acoustic sensor arranged to provide a first acoustic signal, a second acoustic sensor arranged to provide a second acoustic signal, and a processor arranged to receive the first acoustic signal and the second acoustic signal. The processor is programmed to, responsive to an input provided to the first acoustic sensor and the second acoustic sensor, identify a direction of an elevator system noise source based on a first time delay based on the first acoustic signal and the second acoustic signal.

    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.
