A passenger conveyance system () is provided which includes a first component () arranged to rotate about a first rotation axis Aand a second component () arranged to rotate about a second rotation axis A; at least one magnet (); and at least one sensor (). Either the at least one sensor () or the at least one magnet () is fixed to the first component (). The sensor () is arranged to measure a displacement to the at least one magnet (), and the system () is arranged to use the measured displacement to determine information indicative of the alignment of the first and second components ().

Passenger conveyance system

The present invention relates to the field of passenger conveyor technologies, and provides a monitoring system of a passenger conveyor and a monitoring method thereof. In the monitoring system and detection method of the present invention, a monitored object 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 by a processing apparatus to monitor whether the monitored object is in a normal state. The monitored object may include a landing plate, a step, a barrier used in a maintenance and repair working condition and/or a step speed, and the like.

Monitoring system of a passenger conveyor and monitoring method thereof

A conveyor device () comprises: a conveyance element () extending in a longitudinal direction between two spaced apart landing portions () and configured to move for conveying people and/or goods between the two landing portions (); at least one balustrade () located laterally at one side of the conveyance element () and extending along the longitudinal direction of the conveyance element (); and at least one sensor (), which is configured for detecting the presence of a person in a detection zone () which is defined by a main detection direction (D), at least one detection angle (&#x3b1;, &#x3b2;) and at least one detection range (R). The at least one sensor () is located at or next to the at least one balustrade (), and the main detection direction (D) extends from the at least one sensor () in a direction away from the balustrade ().

Conveyor device

A moving handrail monitoring system includes a sensor configured to sense at least part of a moving handrail of the passenger conveying device to acquire a data frame; a processing device configured to analyze and process the data frame to monitor whether a tension degree of the moving handrail is in a normal state, wherein the processing device is configured to include: a target object recognition module configured to recognize, based on a sensed movement and/or position and/or color and/or shape, a moving handrail portion that serves as a target object from the data frame; an object feature extraction module configured to extract a tension degree feature of the moving handrail portion; and a judgment module configured to compare the extracted tension degree feature with a system preset interval, and judge whether a current tension degree of the moving handrail is normal.
