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.
