Runway azimuth based positioning method for airport navigation light photometric characteristic detector

Abstract

The invention discloses a runway azimuth based positioning method for an airport navigation light photometric characteristic detector. According to known parameters including airport runway azimuth, light outgoing width of a lamp and a leaning angle of the lamp as set values, alignment information containing lamp detection distance, optical axis orientation of the lamp and the like can be provided automatically through computer control, so that positioning operation and centering operation for a portable airport navigation light photometric characteristic detector can be finished, when visible laser is adopted for the lamp detection distance and centering information, an alignment point A is also visible, positioning of the portable airport navigation light photometric characteristic detector can be finished in the field conveniently and rapidly according to displayed target value and real-time actual value of reference optical axis orientation of the lamp, operation is simple and convenient, and positioning is accurate.

Description

technical field [0001] The invention relates to a positioning method for a photometric characteristic detector of an airport navigation light, in particular to a positioning method for a photometric characteristic detector of an airport navigation light based on the azimuth angle of a runway, and belongs to the technical field of aircraft guidance and indication. Background technique [0002] The role of the airport navigation lighting system is to provide pilots with visual guidance for attitude control and azimuth alignment during aircraft landing, takeoff or taxiing through four elements: configuration, color, light intensity and effective distribution range. [0003] For the airports that have been put into use, whether the color of the various lamps, the average light intensity of the main beam, and the light intensity distribution curve that constitute the airport navigation lighting system meet the requirements of international standards is the basis for ensuring the n...

Problems solved by technology

[0004] The International Civil Aviation Organization and the civil aviation administrations of various countries have stipulated the corresponding operation and maintenance procedures for the airport navigation aid lighting system, requiring regular inspection of the photometric characteristic parameters such as the color of the lamp, the average light intensity of the main beam, and the light intensity distribution curve to ensure that the airport aid The reliability of the operation of the aviation lighting system. For the photometric characteristic detection equipment that is not accurately positioned, it will cause wrong measurement results due to the deviation angle from the optical axis of the lamp.

[0005] There are two main positioning technologies for on-site security detection equipment. One is the positioning method based on CCD, such as the Chinese invention patent "Positioning method of airport navigation light intensity detection vehicle based on linear array CCD scanning" with application number 2015105946122, The Chinese invention patent with the application number 2015105946141 "Navigation Aid Light Intensity Detection Vehicle Navigation and Positioning System Based on Binocular Vision" and so on, this method requires more than two lamps or airport marking lines as reference points, so in the direction of the runway, the When detecting a single light on the outside of the runway (such as the runway entrance light), the positioning process of the detector is usually very cumbersome; the other is to use the image of the light outlet of the light to be tested on the aiming focus plane and use the perpendicular line of the isosceles trapezoid to locate , this method is complex to adjust and is greatly affected by human factors, and the final positioning needs to be adjusted twice according to the inclination angle of the lamp
