Abstract
The utility model relates to a calibrating device of an airport aid-to-navigation light, which can finish the correction of a PAPI system which only can be finished through airplane flight correction originally, and correction can be finished through utilizing the calibrating device on the ground at present, the precision can be improved by more than twenty times, the cost is greatly lowered, the calibrating device is characterized in that a red filter disc (13) inside a PAPI lamp (1) is close to one side of a light source (10), a non-red semitransparent filer disc (12) is additionally installed and is closely close to the red filter disc (13), the shoot articulation of a pick-up head (6) is intensified, and geodetic surveying and trigonometric function principles are utilized to finish testing the PAPI system.
Description
Technical field:
The utility model relates to a kind of correcting device of airfield aid light, especially a kind of equipment of calibrating in the face of the PAPI system in the navigational lighting aid on ground.
Background technology:
The PAPI system is a kind of light fixture to aircraft indication landing angle, the light that it sends is higher than the indication angle and is white, be lower than the indication angle for red, its legal calibration way is to utilize aircraft to fly aloft to calibrate at present, because the skyborne undulatory property of aircraft, calibration accuracy is lower, and the calibration expense is very high.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of new calibration way, promptly utilizes the way of high precision instrument in the ground calibration.
PAPI system ground prover is characterized in that: the red filter disc 13 of PAPI light fixture 1 inside adds a translucent filter disc 12 of non-redness, and is close to red filter disc 13 near a side of light source 10.
Set up tripod 4 in the dead ahead of PAPI light fixture 1, the center of tripod 4 is equipped with telescopic mark post 9, have scale above the mark post 9, the top device have remote-controlled about, about adjust the colour imagery shot 6 of angle, camera 6 is connected with controller 5 by cable, has display on the controller 5.
Having satisfied above-mentioned requirements just can measure the angle of PAPI light fixture, at first with stadimeter or chi, measure the distance of the middle mark post of PAPI light fixture standard point and tripod, utilize level meter again, measure PAPI light fixture standard point horizontal corresponding point on the mark post scale in the middle of tripod, adjust the collapsing length of mark post then, make the red white interface place of the light that camera just sees that the PAPI light fixture sends, write down the distance of camera and corresponding point, this distance and the ratio of PAPI light fixture standard point to tripod mark post distance, promptly be the tangent value of PAPI light fixture elevation angle theta, can obtain the angle value of PAPI light fixture by inverse trigonometric function.
The beneficial effects of the utility model are; Can improve existing correction accuracy more than 20 times, can save a large amount of calibration flight costs, realize the base-line check of PAPI system.
Description of drawings:
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a systematic schematic diagram of the present invention.
Fig. 2 is the sectional view of PAPI light fixture.
Among the figure: the 1.PAPI light fixture; 2. level meter; 3. level meter support; 4. tripod; 5. controller; 6. camera; 7. standard point; 8. scale value; 9. mark post; 10. light source; 11. reverberator; 12. translucent filter disc; 13 red filter discs; 14. convex lens.
Embodiment:
As shown in Figure 1; Dead ahead at PAPI light fixture 1, set up a tripod 4, a scalable mark post 9 that has scale is equipped with at the center of tripod 4, the top device of mark post 9 have remote-controlled about, the colour imagery shot 6 of left and right sides angle, camera 6 is connected with controller 5 by cable, have display on the controller 5, so that show shooting picture.
While is installed the translucent filter disc 12 of a non-redness additional and is close to red filter disc in a side of the red filter disc 13 close light sources 10 of PAPI light fixture 1 inside.
At first measure distance between the mark post 9 in the middle of standard point 7 on the PAPI light fixture 1 and the tripod 4 with stadimeter or chi, utilize level meter 2 again, measure the horizontal contour point scale value 8 of standard point 7 on mark post 9, adjust the collapsing length of mark post 9 then, make the red white interface place of the light that camera 6 just sees that PAPI light fixture 1 sends, write down the distance of camera 6 and scale value 8, the ratio of this distance and the distance of the scale value 8 of standard point 7 to the mark post 9, promptly be the tangent value of PAPI light fixture 1 elevation angle theta, can obtain the angle value θ of PAPI light fixture 1 by inverse trigonometric function.
After finishing measurement, take off the translucent filter disc 12 of non-redness, recover the PAPI systemic-function.
Claims (3)
1. PAPI system ground prover is characterized in that: the inner red filter disc (13) of PAPI light fixture (1) adds a translucent filter disc of non-redness (12), and is close to red filter disc (13) near a side of light source (10).
2. according to the described PAPI of claim 1 system ground prover, it is characterized in that: set up tripod (4) in the dead ahead of PAPI light fixture (1), the center of tripod (4) is equipped with telescopic mark post (9), have scale above the mark post (9), the top device have remote-controlled about, about adjust the colour imagery shot (6) of angle, camera (6) is connected with controller (5) by cable, and controller has display on (5).
3. according to the described PAPI of claim 1 system ground prover, it is characterized in that: the appropriate location between PAPI light fixture (1) and the tripod, set up level meter (2).
