Abstract

The invention relates to an aircraft automatic berthing technology, in particular to an aircraft berthing automatic guide method and device based on a laser ranging technology. Postures are measured and guided in the aircraft berthing process. The aircraft berthing automatic guide method and device based on the laser ranging technology aim to solve the problems in the prior art. The device comprises a fan-shaped laser scanner, a pitching rotating motor, a processor and a display screen, and the device is arranged at the height position of an aircraft body at the end of the berth of an aircraft. Through the device and an algorithm, the posture of the aircraft is detected in real time when the aircraft is 100 m away from an aircraft stand, guidance (distance, offset and speed) and aircraft type matching information are provided, the information is provided on the display screen in real time, and an aircraft driver is guided to berth the aircraft. When the device is used, no ground manual assistance is needed, and the aircraft driver completes the aircraft berthing operation independently and accurately by relying on prompt information. The device is based on the laser technology, high accuracy is achieved, real-time performance is good, and the device is strong in adaptive capacity under the poor-visibility weather environment, such as haze, snow and rain.

Description

technical field [0001] The invention relates to aircraft automatic berth technology, in particular to an aircraft berth automatic guidance method and device based on laser ranging technology for attitude measurement and guidance during the aircraft berthing process. Background technique [0002] The aircraft parking automatic guidance system can provide accurate and standardized guidance for the safe and efficient parking of aircraft on the apron, and guide the pilot to park the aircraft with the optimal procedure. The aircraft parking process is an integral part of flight operations, and the use of auxiliary equipment to improve the efficiency and safety of flight operations is also an integral part of airport modernization. [0003] In the absence of an automatic aircraft parking guidance system, the parking of an aircraft requires the assistance of multiple ground personnel, and there is room for improvement in execution efficiency. The main task of the aircraft parking ...
