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.
