Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The novel airport runway foreign object auxiliary positioning device of the present invention can automatically select two photoelectric ball machines to emit a bunch of green laser light to the foreign object area respectively when a foreign object is found, and form a green light spot area on the airport runway. The personnel find the green spot according to the guidance of the two beams of light, and look for foreign objects in the area of ​​the spot. Since the airport runway is generally 60m wide and 3000m long, multiple auxiliary positioning devices need to be arranged on each runway; since the installation height of the auxiliary positioning device is relatively low and the irradiation distance is relatively long, the light spot formed by the beam on the ground is a slender Oval, so one beam of light can no longer meet th...

Abstract

The invention provides a novel airport runway foreign object assisted positioning device and a positioning method. The novel airport runway foreign object assisted positioning device comprises at least two assisted positioning devices arranged on the side surface of the airport runway; each assisted positioning device comprises a shell arranged on a pan-tilt; an optical lens group and a green light source are arranged on the shell; a camera is arranged on the rear optical path of the optical lens group; the pan-tilt is internally provided with a main control unit; and the main control unit isconnected with the optical lens group, the green light source and a camera. After the position information of the foreign object in the airport runway is acquired through a radar, the position information is transmitted to the main control unit of the assisted positioning device, the main control unit controls the two assisted positioning devices to rotate, signals are transmitted to open the green light sources of the two assisted positioning devices, the green light paths emitted by the two green light sources cover the area of the foreign object, and on the basis of not changing the existing photoelectric detection system structure, one path of green laser is added to a laser channel for assisted lighting, and a light beam is used for foreign object positioning.

Description

technical field [0001] The invention relates to a novel auxiliary positioning device for foreign objects on airport runways based on laser guidance, and belongs to the technical field of foreign object detection on airport runways. Background technique [0002] After the system detects foreign objects on the airport runway, how to quickly find and remove the foreign objects is the key link in the detection of foreign objects on the entire airport runway. The efficiency of foreign object removal seriously affects the use efficiency of the airport runway. The traditional search method is to determine the approximate range of the foreign object and then check it. It is relatively inefficient to search for an area not larger than 2cmX2cm within a range of tens of meters. Therefore, in order to improve the removal efficiency of foreign matter, it is urgent to design a device that can guide the staff to quickly locate the foreign matter. Contents of the invention [0003] The i...
