Abstract: An elevator system includes a component adapted to perform a function, a sensor, and a control configuration. The sensor is configured to detect an operating parameter associated with the function. The control configuration is configured to receive a parameter signal from the sensor, and extract a predesignated feature from data associated with the parameter signal. The predesignated feature is then aggregated by the control configuration and machine learning is applied to determine a degradation level of the function associated with the predesignated feature.

Abstract: A method of monitoring a conveyance apparatus within a conveyance system is provided. The method including: obtaining a starting location position probability distribution of the conveyance apparatus within the conveyance system; detecting motion of the conveyance apparatus away from the probable starting location for a period of time; determining a distance traveled by the conveyance apparatus during the period of time; determining a direction of motion of the conveyance apparatus during the period of time; and determining a probability of the conveyance apparatus being at each of a plurality of possible destination locations at a conclusion of the period of time in response to the starting location position probability distribution and at least one of the distance traveled, the direction of motion, and the period of time.

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: Embodiments include a system and method for scheduling maintenance based on remote monitoring data and service data analytics. The embodiments include a controller configured monitor performance of one or more units, a remote system configured to store service data associated with the one or more units, and a processor operably coupled to the controller and the remote system. The processor is configured to receive monitoring data from the controller for the one or more units, and receive service data for the one or more units. The remote system is also configured to generate a health score based at least in part on the monitoring data and the service data. The processor is further configured to predict a failure based at least in part on the health score, and execute an action based at least in part on the generated health score.
