  • Patent number: 11319190
    Abstract: A passenger conveyance system (2, 102, 202) is provided which includes a first component (12, 112, 212) arranged to rotate about a first rotation axis A1 and a second component (16, 116, 216) arranged to rotate about a second rotation axis A2; at least one magnet (20,120, 220); and at least one sensor (24, 124, 224). Either the at least one sensor (24, 124, 224) or the at least one magnet (20, 120, 220) is fixed to the first component (12, 112, 212). The sensor (24, 124, 224) is arranged to measure a displacement to the at least one magnet (12, 112, 212), and the system (2, 102, 202) is arranged to use the measured displacement to determine information indicative of the alignment of the first and second components (12, 112, 212; 16, 116, 216).

  • Patent number: 10282847
    Abstract: 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.

  • Patent number: 10259685
    Abstract: A conveyor device (2) comprises: a conveyance element (8) extending in a longitudinal direction between two spaced apart landing portions (4, 6) and configured to move for conveying people and/or goods between the two landing portions (4, 6); at least one balustrade (10, 12) located laterally at one side of the conveyance element (8) and extending along the longitudinal direction of the conveyance element (8); and at least one sensor (22, 23), which is configured for detecting the presence of a person in a detection zone (28) which is defined by a main detection direction (D), at least one detection angle (?, ?) and at least one detection range (R). The at least one sensor (22, 23) is located at or next to the at least one balustrade (10, 12), and the main detection direction (D) extends from the at least one sensor (22, 23) in a direction away from the balustrade (10, 12).

  • Patent number: 10221046
    Abstract: 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.

  • Publication number: 20180029836
    Abstract: A temperature monitoring system for a passenger transport apparatus includes a temperature detection apparatus; and a control apparatus. When the temperature of at least one of a plurality of components is lower than a working temperature range, the control apparatus sends out a notification message and/or enables a heating apparatus to heat the component; when the temperature of at least one of the plurality of components reaches an early warning temperature range, the control apparatus sends out a notification message and/or enables a heat dissipation apparatus to dissipate heat for the component; and when the temperature of at least one of the plurality of components continues to rise and exceeds the working temperature range, the control apparatus sends out a notification message and/or enables the passenger transport apparatus to brake. The present invention is able to monitor a component running condition and predict a component service life.
