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: The present invention provides a handrail entry monitoring system of a passenger conveyor and a monitoring method thereof, and belongs to the field of passenger conveyor technologies. In the handrail entry monitoring system and the monitoring method of the present invention, at least part of a handrail entry region of the passenger conveyor is sensed by using an imaging sensor and/or a depth sensing sensor, to acquire a data frame, and the data frame is analyzed to monitor whether a handrail entry of the operating passenger conveyor is in a normal state or an abnormal state. The monitoring system of the present invention and the monitoring method thereof can timely and effectively detect a danger that a foreign matter is about to be entrapped into the handrail entry, helping prevent foreign matters from being entrapped into the handrail entry, thereby improving safety of the passenger conveyor.

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.

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.
