Embodiment Construction

[0019] refer to Figure 1 to Figure 4 , an airport PAPI light verification system based on a tethered hovering unmanned aerial vehicle proposed by the present invention;

[0020] Such as figure 2 as shown, figure 2 It is a schematic diagram of the structure of the PAPI lamp;

[0021] figure 2 Among them, ① is a white light source, ② is a red filter, ③ is two lenses, ④ a white light area, ⑤ a red light area; the white light beam emitted by the white light source ① passes through the red filter ② in the upper part of the lamp tube, The upper half of the light beam becomes red light, and then refracted by two lenses ③, the upper half of the light beam is a white light area ④ after being emitted from the lamp tube, and the lower half is a red light area ⑤;

[0022] Such as image 3 as shown, image 3 Schematic diagram of the visual navigation for the PAPI signal to slide down;

[0023] refer to image 3 , the pilot will see different combinations of red or white PAPI li...

Abstract

The invention discloses an airport PAPI light verification system based on a mooring hovering unmanned aerial vehicle. The system comprises a flight platform, a ground platform and a control module. The control module is in communication connection with the flight platform and the ground platform, and the flight platform is connected with the ground platform through a photoelectric composite cable; the control module instructs and controls the flight platform to vertically go up at two preset collection points to obtain an image of PAPI light and three-dimensional position information of an unmanned aerial vehicle, convert the image information of the PAPI light to HDMI / SDI signals, convert the HDMI / SDI signals to the image optical signals of the PAPI light and transmit the image optical signals of the PAPI light and the corresponding three-dimensional position information to the photoelectric composite cable to the ground platform, the ground platform converts the image optical signals of the PAPI light to the HDMI / SDI signals of the PAPI light image, the height of the unmanned aerial vehicle is determined when the PAPI light is a preset color according to the PAPI light image indicated by the PAPI light image HDMI / SDI signals and the three-dimensional position information of the unmanned aerial vehicle, the height of the unmanned aerial vehicle is compared with a preset height threshold value, and the angle of the PAP is regulated according to a comparison result.

Description

technical field [0001] The invention relates to the technical field of lighting verification, in particular to an airport PAPI lighting verification system based on a tethered hovering unmanned aerial vehicle. Background technique [0002] The Precision Approach Path Indicator (PAPI) system is of great significance to flight safety. The instrument usually consists of four lights, which are placed on the left side of the runway in the landing direction of the aircraft. The light of each light is projected to the aircraft glideslope at the elevation angles of 2.42°, 2.75°, 3.25°, and 3.58° respectively. Accurately approximates the pilot in the environment to provide visual taxi slope guidance. The pilot will see different combinations of red or white PAPI lights at different angles of descent. If the approach angle of the pilot is correct, the PAPI lights should be displayed as two white and two red. If three white and one red or Four white lights indicate that the approach ...
