Abstract: According to an aspect, an elevator sensor calibration system includes one or more sensors operable to monitor an elevator system, an elevator sensor calibration device, and a computing system. The computing system includes a memory and a processor that collects a plurality of baseline sensor data from the one or more sensors during movement of an elevator component, collects a plurality of disturbance data from the one or more sensors while the elevator component is displaced responsive to contact with the elevator sensor calibration device during movement of the elevator component, and performs analytics model calibration to calibrate a trained model based on one or more response changes between the baseline sensor data and the disturbance data.

Abstract: An illustrative example embodiment of an elevator system includes a plurality of components respectively configured for at least one function during operation of the elevator system. A plurality of sensors are each associated with at least one of the components. Each sensor senses at least one characteristic of an actual performance of an associated one of the components. A processor is configured to receive respective indications from the sensors regarding the actual performance of the associated components, determine a difference between the actual performance and a desired performance of any of the components based on the respective indications, and determine an adjustment to the operation of the elevator system based upon the determined difference.
