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 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.
