Abstract: A monitoring system for a passenger conveyor including: at least one acceleration sensor provided on a movable component of the passenger conveyor, wherein the moveable component moves in a closed loop path (P) when the passenger conveyor is in use; a fault detection sensor associated with the or each acceleration sensor and configured to provide data indicative of a fault in the moveable component. The monitoring system includes a controller configured to: receive data from the or each acceleration sensor; monitor a gravity vector (V) of the or each acceleration sensor; determine a direction of travel of the or each acceleration sensor; determine a current location of the or each acceleration sensor based on the monitored gravity vector (V) and the determined direction of travel; detect a fault from the data received from the or each fault detection sensor; identify a location of the detected fault.

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: 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: 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.
