Passenger boarding bridge monitoring device for detecting crossing virtual lines
A recently filed patent (Publication Number: US20230271722A1) describes a passenger boarding bridge monitoring device that aims to improve the docking and undocking process of multiple passenger boarding bridges with an aircraft. The device includes a rotunda, a tunnel unit, a travel device with wheels, a rotatable cab, and various detectors.
The device features a line calculator that calculates the current position of a virtual line for each adjacent passenger boarding bridge based on detection values from the detectors. The virtual line is set in a way that it is shifted outward from the profile of the bridge on its side adjacent to the other bridge. The line calculator ensures that the virtual line conforms to the shape of the bridge's profile. The monitoring controller then determines whether the virtual lines of the two bridges are in a state of crossing each other based on a predetermined crossing determination condition. If the virtual lines are determined to be crossing, the monitoring controller performs a first coming-close hindering process to prevent any potential collision.
Additionally, the monitoring controller can determine whether the virtual lines are in a state of being close to each other based on a predetermined closeness determination condition. If the virtual lines are determined to be close, the monitoring controller performs a second coming-close hindering process to further ensure safety during the docking and undocking process.
The passenger boarding bridge monitoring device also includes a display device on each bridge and a display data generator. The display data generator generates display data that shows the current positions of the virtual lines on the display devices. This allows operators and personnel involved in the docking and undocking process to have a visual representation of the positions of the bridges and the virtual lines, aiding in their decision-making and ensuring smooth operations.
The line calculator in the device calculates the current positions of the virtual lines for each bridge using coordinates of a single orthogonal coordinate system, where a predetermined position is set as the origin. This simplifies the calculation process and ensures accurate positioning of the virtual lines.
Overall, this patent describes a passenger boarding bridge monitoring device that utilizes virtual lines and various detectors to enhance safety and efficiency during the docking and undocking process of multiple bridges with an aircraft. The device provides real-time monitoring, hindering processes to prevent collisions, and visual displays of the bridge positions, contributing to a smoother and safer boarding experience for passengers.
