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.
