Abstract: A method of examining an electrical safety chain of an elevator system including: emitting an electric pulse from a time-domain reflectometer into an electrical safety chain of an elevator system; detecting a reflected electric pulse reflected within the electrical safety chain using the time-domain reflectometer; comparing the reflected electric pulse to a baseline reflected electric pulse; and determining a degradation level in response to the reflected electric pulse and the baseline reflected electric pulse.

Abstract: According to an aspect, a method of elevator sensor system calibration includes collecting, by a computing system, a plurality of baseline sensor data from one or more sensors of an elevator sensor system as a field-site baseline response. The computing system compares the field-site baseline response to an experiment-site baseline response. The computing system performs analytics model calibration to produce a calibrated trained model for fault diagnostics and/or prognostics based on one or more response changes between the field-site baseline response and the experiment-site baseline response.

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: According to an aspect, a method of elevator sensor system calibration includes collecting, by a computing system, a plurality of data from one or more sensors of an elevator sensor system while a calibration device applies a known excitation. The computing system compares an actual response to an expected response to the known excitation using a trained model. The computing system performs analytics model calibration to calibrate the trained model based on one or more response changes between the actual response and the expected response.

Abstract: A mobile-based equipment service system includes a remote server, a mobile device, and at least one equipment controller. The mobile device includes a user interface, and is configured to send a user authentication message, initiated by a user via the user interface, to the remote server. The remote server is configured to verify the user via the user authentication message and once verified, send an encrypted blob to the mobile device in response to the user authentication message. At least one equipment controller is configured to receive and decrypt the encrypted blob from the mobile device.

Abstract: A monitoring system includes one or more detection devices, a communication device, and an analytics system. The one or more detection devices generate, at a conveyance system, one or more data streams describing the ride of the conveyance system, where the data streams include at least one of vibration data and audio data. The communication device transmits sensor data based on the one or more data streams. The analytics system receives the sensor data from the communication device and, based on the sensor data, determines a ride quality of the conveyance system.

Abstract: Embodiments include techniques for developing a model framework for remote unit monitoring condition-based maintenance. The techniques include collecting data associated with unplanned service requests, and generating one or more models from the collected data. The techniques also include predicting unplanned service requests based at least in part on the one or more models, and transmitting an output of the prediction of the unplanned service request.

Abstract: An elevator vandalism monitoring system is configured to determine if an act of vandalism upon a component of an elevator system has occurred. The vandalism monitoring system includes a sensor, a processor, an electronic storage medium, a model, and a comparison module. The sensor is configured to monitor a detectable parameter associated with the component, and output a detectable parameter signal. The processor is configured to receive the detectable parameter signal. The model is stored in the electronic storage medium, and is associated with an expected parameter. The comparison module is executed by the processor, and is configured to generally compare the model to the detectable parameter signal for determining if a parameter anomaly exists.
