摘要： 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.

摘要： 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.
