Air bridge and automatic abutting method therefor

Abstract

The invention relates to an air bridge and an automatic abutting method therefor. The air bridge comprises an airplane connector, a lifting mechanism, a travelling mechanism and an automatic abutting device. The automatic abutting device comprises an image data acquisition unit, a preprocessing unit, a database, a visual identification and positioning unit, a motion control unit and a bridge control system. When an airplane parks at a parking position and the air bridge automatically abuts at an initial position, the automatic abutting device is started; image data of a hatch door of the airplane, included in the image data acquisition unit, is preprocessed; an image meeting the features of the hatch door of the airplane is recognized from the processed image data; information about the position of the airplane connector relative to the hatch door is calculated; travel control information is generated according to the information about the relative position; the relative position information and the travel control information are encoded and transmitted to the bridge control system; finally, the received information is decoded, the travel control information is executed, and the air bridge is driven to move until automatically abutting to the hatch door.

Description

technical field [0001] The invention relates to a boarding bridge equipped with an automatic docking device for aircraft doors and an automatic docking method thereof. Background technique [0002] The boarding bridge is the tool and channel for the airport to connect the terminal building and the aircraft so that passengers can get on and off the plane. According to different aircraft models, there are many types of boarding bridges, but at present, the boarding bridges are basically operated by professionals to realize the docking of the boarding bridge and the aircraft door. However, the operation panel and controls of the boarding bridge will vary greatly depending on the requirements of the airport. Therefore, in order to achieve a safe, reliable and accurate docking, strict technical training of the boarding bridge operators is required. At the same time, the professional operator's operation of docking the boarding bridge with the aircraft door is affected by factor...

Problems solved by technology

[0005] However, this has great limitations. First of all, it is not very operable to install infrared reflectors under the doors of each aircraft, and it is also very difficult to maintain and monitor; moreover, in the airport environment, there are many Devices that reflect infrared rays may cause interference to the system; thirdly, camera imaging systems are susceptible to interference from weather conditions, and infrared rays are also susceptible to interference from rain, snow, and fog
