  • Patent number: 10724586
    Abstract: A passenger boarding bridge having a movable tunnel and braking system includes a brake plate, a brake pin and a triggering device. The brake plate is fixedly disposed at a first tunnel of the plurality of tunnels, and the brake plate is provided with a plurality of brake slots. The brake pin is movably disposed at a second tunnel of the plurality of tunnels, which is sleeve-connected with the first tunnel and can be combined with the brake slot. The triggering device includes a mechanical blocking portion, a linkage mechanism and a tensile spring. The mechanical blocking portion is fixedly disposed at the second tunnel. When the tensile wire rope or the retracting wire rope is broken, the linkage mechanism is driven to move and drives the brake pin to combine with the brake slot, to brake the first tunnel and the second tunnel.

  • Patent number: 10562644
    Abstract: A laser scanning-based aircraft docking guidance system and method, the method comprising: a capturing step: laser scanning in the horizontal direction is performed on a position where the head of an aircraft is expected to appear, echo data based on the laser scanning is obtained, and the echo data is judged according to a judging condition, so as to determine whether the aircraft has appeared; a guiding step: after the aircraft has appeared, laser scanning in the horizontal direction is performed on the head of the aircraft, echo data based on the laser scanning is obtained, and the position of the nose of the aircraft is determined; a tracking step: as the aircraft moves forward, the position of the nose is tracked by adjusting the vertical scanning angle of the laser scanning, and the position of the nose is displayed in real time.

  • Patent number: 10255520
    Abstract: A system and method for aircraft docking guidance and aircraft type identification. The method is executed in the system for aircraft docking guidance and aircraft type identification comprising a machine vision sub-system, a laser scanning sub-system and a fusion module. The method includes: in step 1000, obtaining, by the machine vision sub-system, an image via image capturing means, and calculating a first aircraft front wheel position therefrom; in step 2000, obtaining, by the laser scanning sub-system, the position of the nose of an aircraft via laser scanning means, and calculating a second aircraft front wheel position; in step 3000, fusing the first aircraft front wheel position and the second aircraft front wheel position according to a fusion rule, to obtain deviation of an aircraft front wheel.
