Abstract: The present invention relates to the field of passenger conveyor technologies, and provides an engaging state detection system of a passenger conveyor and a detection method thereof. In the engaging state detection system and detection method of the present invention, a depth sensing sensor is used to sense at least an engaging portion between a step and a comb plate of the passenger conveyor to obtain depth maps, and the depth maps are analyzed by a processing apparatus to detect whether an engaging state between the step and the comb plate is a normal state. The detection of the engaging state includes detection on whether comb teeth of the comb plate are broken, whether engaging teeth of the step are broken, and/or whether a foreign matter exists on an engaging line.

Abstract: A passenger conveyance system includes a depth-sensing sensor within a passenger conveyance enclosure for capturing depth map data of objects within a field of view that includes a passenger conveyance door. A processing module in communication with the depth-sensing sensor to receive the depth map data, the processing module uses the depth map data to determine that the passenger conveyance enclosure is empty. a passenger conveyance controller receives the passenger data from the processing module to control operation of a passenger conveyance door in response to an empty car determination.

Abstract: A passenger conveyance passenger tracking control system that controls operation of a passenger conveyance, e.g., an elevator car, includes at least one call request device, e.g., a call request panel, configured to receive at least one input from at least one passenger located at a occupancy depth grid. At least one passenger position three-dimensional (3-D) depth-sensing sensor is configured to track a position of the at least one passenger located at the occupancy depth grid. The passenger conveyance passenger tracking control system further includes an electronic control module in signal communication with the at least one call request device and at least one passenger position 3-D depth-sensing sensor. The electronic control module is configured to control operation of the passenger conveyance based on the position of the at least one passenger.

Abstract: A passenger tracking system includes a multiple of sensors for capturing depth map data of objects. A processing module in communication with the multiple of sensors to receive the depth map data, the processing module uses the depth map data to track an object and calculate passenger data associated with the tracked object to generate a passenger tracking list that tracks each individual passenger in the passenger data from an origin lobby to a destination lobby and through an in-car track between the origin lobby and the destination lobby.

Abstract: An elevator system is provided and includes a sensor assembly and a controller. The sensor assembly is disposable in or proximate to an elevator lobby and is configured to deduce an intent of an individual in the elevator lobby to board one of one or more elevators and to issue a call signal in response to deducing the intent of the individual to board the one of the elevators. The controller is configured to receive the call signal issued by the sensor assembly and to assign one or more of the elevators to serve the call signal at the elevator lobby.
