Abstract: A passenger conveyor system and an anti-collision device for step and comb plate. The passenger conveyor system includes a step chain having a plurality of steps, a comb plate and an anti-collision device, the anti-collision device includes an actuating mechanism connected to the comb plate and configured to, when a moving distance of a step adjacent to comb teeth of the comb plate to be engaged in a vertical upward direction of the passenger conveyor system exceeds a preset value, actuate the comb plate to be lifted up from an initial first position to a second position to avoid collision with the step; and a reset mechanism configured to return the comb plate from the second position to the first position after the step travels through the comb plate.

Abstract: An escalator system is provided and includes a combplate including teeth, a moving step including grooves and being drivable to pass by the combplate at a step-combplate interface at which, when each tooth is correctly positioned, each tooth passes through a corresponding groove and a detection system. The detection system includes an emitter and receiver pair and is configured to determine whether a signal pattern, which is derived from communications of the emitter and receiver pair and which is partially reflective of conditions of the teeth, is indicative of at least one tooth being incorrectly positioned.

Abstract: A brake system for a conveyor system. The brake system includes a brake, a distance detection device and a controller. The brake includes a brake arm and a brake lining connected to the brake arm. The distance detection device is arranged on the brake for detecting a first distance and a second distance between the brake arm and a brake drum, where the first distance is a distance between the brake arm and the brake drum when the brake is in an open state, and the second distance is a distance between the brake arm and the brake drum when the brake is in a closed state. The controller is used for determining a brake performance of the brake based on a difference between the first distance and the second distance detected sequentially, and for generating and sending warning signals when the difference is not within a preset range.

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.
