[0001] The present invention relates to airport navigation aids, and particularly to an adjustment device for optical calibration of approach navigation lights. Background Art

[0002] Airport lights are a general term for the lighting signs installed in the specified areas of the airport to provide visual guidance for aircraft taking off, landing, and taxiing at night or in low visibility conditions; airport runway navigation lights such as centerline lights and approach lights are extremely important navigation aids for airport runways. They are generally installed in an embedded manner on the ground, and the navigation lights generally consist of an approach lighting system, a runway lighting system, a taxiway lighting system, etc.

[0003] During the on-site construction self-inspection and acceptance process, it is found that a large amount of manpower is required each time to check the optical core elevation and luminous elevation angle of the approach lights. Especially for the temporary approach lights in the reconstruction and expansion projects of non-stop construction projects, they need to be checked in a short time, and the management pressure on operation safety is particularly prominent, and urgent improvement is needed. Summary of the Invention

[0004] In order to reduce the management pressure for checking the temporary approach lights, the present application provides an adjustment device for optical calibration of approach navigation lights.

[0005] The present application provides an adjustment device for optical calibration of approach navigation lights, including a device main body, a horizontal self-calibration mechanism, a light intensity detection sensor, and an intelligent processing device. The device main body is provided with a connection end for connecting with the approach navigation lights. The connection end is provided with a light collection port. The device main body is provided with a light collection cavity communicating with the light collection port. The horizontal self-calibration mechanism includes a horizontal light collection plate for the light to enter and a horizontal reset mechanism for resetting the horizontal light collection plate. The horizontal light collection plate is hinged to the inner wall of the light collection cavity. The hinge axis of the horizontal light collection plate is perpendicular to the axis of the light collection port. A plurality of light intensity detection sensors are installed on the horizontal light collection plate. The light intensity detection sensor located at the axis of the light collection port is a standard light intensity detection sensor. The intelligent processing device is coupled to the light intensity detection sensor. The intelligent processing device includes: a light intensity detection signal receiving module for receiving the standard light intensity detection signal of the standard light intensity detection sensor and the plurality of light intensity detection signals sent by the plurality of light intensity detection sensors;

[0006] A processing module for obtaining the luminous elevation angle of the lamp according to the standard light intensity detection signal and the plurality of light intensity detection signals.

[0007] By adopting the above technical solution, personnel install the adjustment device for optical calibration of the approach aid lights on the approach aid lights through the connection end. Then, the intelligent processing device processes the standard light intensity detection signal detected by the light intensity detection sensor and multiple light intensity detection signals to automatically obtain the luminous elevation angle of the lights, which is relatively convenient. There is no need for personnel to spend a lot of manpower on the calibration of the luminous elevation angle, reducing the management pressure for calibrating the temporary approach lights.

[0008] Optionally, the intelligent processing device is also coupled with a positioning sensor for emitting positioning coordinate information. The positioning sensor is installed on the device body. The intelligent processing is wirelessly connected to a base station, and the base station is used to obtain the elevation information of the lights based on the built-in standard coordinate plane and the positioning coordinate information and display it.

[0009] By adopting the above technical solution, personnel can understand the positioning coordinate information of the positioning sensor through the display of the base station, so that after adjusting the luminous elevation angle of the approach aid lights optically by using the adjustment device for optical calibration of the approach aid lights, personnel can adjust the elevation of the approach aid lights optically according to the displayed positioning coordinate information.

[0010] Optionally, two positioning sensors are provided along the direction parallel to the hinge axis of the horizontal light collecting plate, and the base station is also used to obtain the rotation axis direction information of the lights based on the built-in standard coordinate plane and the positioning coordinate information.

[0014] By adopting the above technical solution, since the light obliquely enters the horizontal light collecting plate, the distance between the incident point at the edge of the light collecting port and the horizontal light collecting plate is the closest or the farthest, so the light intensity detection signal detected by the corresponding light intensity detection sensor is the maximum or the minimum. And the shape of the light collecting port can be determined, so the luminous elevation angle of the lights is obtained according to the light intensity calculation formula.

[0015]

[0016] Optionally, the processing module further includes, and the preset light intensity calculation formula is:

[0017] Among them, E is the light intensity, Φ is the luminous flux, L is the distance between the light source and the light intensity detection sensor, L = d + r / tanα, α is the upward emission angle of the lamp, d is the distance from the daylighting opening to the standard light intensity detection sensor, and r is the radius of the daylighting opening.

[0018] By adopting the above technical solution, personnel can substitute the standard light intensity detection signal and the maximum light intensity detection signal into the formula of the light intensity calculation formula respectively, calculate the upward emission angle, and calculate the upward emission angle through the difference in light intensity at different positions on the horizontal daylighting plate, making the detection of the upward emission angle more convenient.

[0019] Optionally, the intelligent processing device further includes:

[0020] A display module for displaying the upward emission angle of the lamp through a display coupled to the intelligent processing device.

[0021] By adopting the above technical solution, the display module is convenient for displaying the upward emission angle to relevant personnel through the display, facilitating personnel to quickly understand the specific value of the upward emission angle.

[0022] Optionally, the horizontal reset mechanism includes a hinge rod, a driving member, a weight, and a driven adjustment component. The driven adjustment component includes two parallel rods. The hinge rod is hinged to the inner wall of the daylighting cavity. The weight is suspended at the end of the hinge rod far from the hinge by a pull rope. The driving member is vertically fixed on the rod wall of the hinge rod. The two parallel rods are arranged in parallel. One ends of the two parallel rods are both hinged to the driving member, and the other ends are both hinged to a sliding sleeve slidably arranged on the horizontal daylighting plate.

[0023] By adopting the above technical solution, a parallelogram mechanism is formed among the two parallel rods, the driving member, and the horizontal daylighting plate. After the weight adjusts the driving member to be horizontal through the hinge member, the driving member drives the horizontal daylighting plate to be adjusted to be horizontal through the parallelogram mechanism, so that the horizontal daylighting plate always maintains a horizontal state.

[0024] Optionally, the intelligent processing device further includes:

[0025] A light intensity detection sensor fault alarm module for judging whether the light intensity detection signals sent by two adjacent light intensity detection sensors conform to the preset light intensity change standard;

[0026] If not, it controls an alarm device coupled to the intelligent processing device to emit an alarm.

[0027] By adopting the above technical solution, the setting of the light intensity detection sensor fault alarm module can prompt personnel to perform maintenance after the light intensity detection sensor fails, avoiding inaccurate upward emission angle detection results caused by the failure of the light intensity detection sensor.

[0028] Optionally, the intelligent processing device further includes:

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0047] Referring to Figure 1 and Figure 2 , an adjustment device for optical calibration of approach navigation lights, includes a device main body 1, a horizontal self-calibration mechanism 2, a light intensity detection sensor 3, and an intelligent processing device 4, which is mainly used to adjust the elevation angle of light emission, the rotation axis, and the elevation of approach navigation lights, as follows:

[0048] The device main body 1 is provided with a connection end 11 for connecting with the approach navigation light. The connection end 11 has a socket adapted to the shape of the light-emitting end of the approach navigation light. After the device main body 1 is connected to the approach navigation light, the light-emitting end of the approach navigation light is closed, so that the light emitted by the approach navigation light enters the adjustment device.

[0049] The connection end 11 is provided with a daylighting port 12. The daylighting port 12 is circular and located at the center of the connection end 11. A daylighting cavity 121 communicating with the daylighting port 12 is provided in the device main body 1. The horizontal self-calibration mechanism 2 includes a horizontal daylighting plate 21 for allowing light to enter and a horizontal reset mechanism 22 for resetting the horizontal daylighting plate 21.

[0050] Referring to Figure 2 and Figure 3, the horizontal daylighting plate 21 is hinged to the inner wall of the daylighting cavity 121, and the hinge axis of the horizontal daylighting plate 21 is perpendicular to the axis of the daylighting port 12. The horizontal reset mechanism 22 includes a hinge rod 221, a driving member 222, a weight 223, and a driven adjustment component 224. The driven adjustment component 224 includes two parallel rods 225. The hinge rod 221 is hinged to the inner wall of the daylighting cavity 121, and the hinge axis of the hinge rod 221 is parallel to the hinge axis of the horizontal daylighting plate 21. The driving member 222 is in the shape of a plate and is vertically fixed to the rod wall of the hinge rod 221. The weight 223 is suspended from the end of the hinge rod 221 far from the hinge by a pulling rope, so that the hinge rod 221 always remains vertical and thus the driving member 222 always remains horizontal. The two parallel rods 225 are arranged parallel to each other. The horizontal daylighting plate 21 is fixed with a protruding column 227. The axial direction of the protruding column 227 is perpendicular to the hinge axis of the horizontal daylighting plate 21. One end of each of the two parallel rods 225 is hinged to the driving member 222, and the other end is hinged to a sliding sleeve 226 slidably sleeved on the protruding column 227. The sliding direction of the sliding sleeve 226 is perpendicular to the axis direction of the rotating shaft of the horizontal daylighting plate 21, so that a parallelogram mechanism is formed among the two parallel rods 225, the sliding sleeve 226, and the driving member 222. The sliding sleeve 226 is adapted to the protruding column 227, so that the sliding sleeve 226, the horizontal daylighting plate 21, and the driving member 222 always remain horizontal, and can overcome the change in the relative distance during the rotation of the horizontal daylighting plate 21 and the hinge rod 221, so that the horizontal reset mechanism 22 can always work properly;

[0051] Referring to Figure 3 and Figure 4 , a plurality of light intensity detection sensors 3 are installed on the bottom surface of the horizontal daylighting plate 21. Among them, since the distance from the axis of the daylighting port 12 to the rotating shaft of the horizontal daylighting plate 21 is constant, the light intensity detection sensor 3 located at the axis of the daylighting port 12 is used as the standard light intensity detection sensor 31. The plurality of light intensity detection sensors 3 are equidistantly spaced along the axis direction of the rotating shaft of the horizontal daylighting plate 21. The number and distribution density of the light intensity detection sensors 3 are not specifically limited here and can be set according to the actual required accuracy;

[0052] It should be noted that all the light intensity detection sensors 3, including the standard light intensity detection sensor 31, are coupled to the intelligent processing device 4, and the collected light intensity detection signals are transmitted to the intelligent processing device 4 for the intelligent processing device 4 to process and obtain the luminous elevation angle of the lamp;

[0053] The specific processing process is as follows:

[0054] Referring to Figure 4 and Figure 5, the intelligent processing device 4 can specifically be a single-chip microcomputer; the intelligent processing device 4 includes a light intensity detection signal receiving module 41, a processing module 42, a display module 43, a fault alarm module for the light intensity detection sensor 3, and a prompt module 45. The above modules can be program modules stored in the single-chip microcomputer;

[0055] The light intensity detection signal receiving module 41 is used to receive the standard light intensity detection signal of the standard light intensity detection sensor 31 and multiple light intensity detection signals sent by multiple light intensity detection sensors 3; among them, the light sensor is an existing sensor used to detect the light intensity, abbreviated as illuminance, and its working principle is to convert the light intensity value into a voltage value;

[0056] The processing module 42 is used to obtain the luminous elevation angle of the lamp according to the standard light intensity detection signal and multiple light intensity detection signals;

[0057] Specifically, the processing module 42 includes a light intensity detection signal screening unit 421 and a luminous elevation angle calculation unit 422;

[0058] The light intensity detection signal screening unit 421 is used to screen the maximum light intensity detection signal among multiple light intensity detection signals; specifically, since the adjustment device for the optical calibration of this approach navigation lamp is installed on the approach navigation lamp, the horizontal daylighting plate 21 will return to and maintain a horizontal state. However, after the horizontal daylighting plate 21 returns, the light of the approach navigation lamp is obliquely incident into the horizontal daylighting plate 21 through the daylighting hole along the elevation angle direction of the lamp, and thus is detected by each light intensity detection sensor 3 on the horizontal daylighting plate 21. And because the light is obliquely incident, the distances from each point on the lower surface of the horizontal daylighting plate 21 to the daylighting port are different. According to the luminous flux formula, it can be known that there is a definite relationship between the light intensity on the horizontal daylighting plate 21 and the incident distance, and the incident distance is determined by the elevation angle of the lamp and the light incident point. And the incident points of the maximum light intensity detection signal and the minimum light intensity detection signal can be determined to be the upper and lower sides of the daylighting port 12. Therefore, detecting the maximum light intensity detection signal or the minimum light intensity detection signal can determine the position of the daylighting point on the daylighting plate, and thus obtain the luminous elevation angle of the lamp;

[0059] In another embodiment, the position of the light intensity detection sensor 3 can also be marked, so that each collected light intensity detection signal in the single-chip microcomputer is attached with a distance value from the standard light intensity detection sensor 31 according to the collection position. In this way, the distance from the daylighting point on the daylighting plate to the daylighting port can also be determined to calculate the light elevation angle of the lamp. Specifically:

[0060] The luminous elevation angle calculation unit 422 is used to obtain the luminous elevation angle of the lamp according to the maximum light intensity detection signal, the standard light intensity detection signal, and a preset light intensity calculation formula;

[0061] The light intensity calculation formula is as follows:

[0062] where E is the illumination intensity, Φ is the luminous flux at the detection point of the light intensity detection sensor 3, L is the distance between the light source and the light intensity detection

[0063]

[0064] sensor 3, α is the upward emission angle of the lamp, L = d + r / tanα, d is the distance from the daylighting opening 12 to the standard light intensity detection sensor 31, and r is the radius of the daylighting opening 12.

[0065] Since the daylighting opening is directly opposite to the center of the lamp core of the approach navigation lamp, the collected light is equivalent to parallel light, and the luminous intensity and luminous flux at each part of the daylighting opening can be regarded as the same. The distance value and upward emission angle of the standard light intensity detection sensor 31 are fixed, and the distance value d is determined. For the standard light intensity detection sensor 31, L = d. Substitute the illumination intensity E received by the standard light intensity detection sensor 31 and L = d into the above formula to obtain the luminous flux Φ. Then, substitute the luminous flux Φ, L = d + r / tanα, and the minimum illumination intensity E detected by the light intensity detection sensor 3 into the above formula to obtain the upward emission angle α. In addition, in another embodiment, to improve the accuracy, the average value of the upward emission angles obtained by substituting the maximum illumination intensity detection signal and the minimum illumination intensity detection signal into the above formula respectively can be taken as the finally obtained upward emission angle.

[0066] In other embodiments, the distance value c between the light intensity detection sensor 3 corresponding to the illumination intensity detection signal and the standard light intensity detection sensor 31 can also be used. Through L = d + c.cosα, and then through the same logic calculation, the upward emission angle can also be obtained.

[0067] In another embodiment, the illumination intensity detection signals of the light intensity detection sensors 3 with a distance of c from both sides of the standard light intensity detection sensor 31 can also be collected. The distances from the two light intensity detection sensors 3 to the daylighting opening 12 are d + c.cosα and d - c.cosα respectively. Therefore, through the above light intensity calculation formula, it can be obtained that the reciprocal of the ratio of the squares of the distances from the two to the daylighting opening 12 is equal to the ratio of the illumination intensity detection signals of the two. Thus, the upward emission angle α can be obtained through equation calculation.

[0068] In addition, this embodiment also provides a technical method for the luminous elevation angle of the lamp core of an approach navigation lamp being a point light source. Specifically, first, the light intensity signals collected by the standard light intensity detection sensor 31 and the light intensity detection sensors 3, each of which is at a distance of c from the standard light intensity detection sensor 31, are substituted into the light intensity calculation formula to obtain the distance from the light intensity detection sensors 3, each of which is at a distance of c from the standard light intensity detection sensor 31, to the lamp core. Then, since the standard light intensity detection sensor 31, the corresponding light intensity detection sensor 3 at the detection point, and the lamp core form a triangle with determined side lengths, by calculating the included angle of the triangle, the angle between the line formed by the lamp core and the standard light intensity detection sensor 31 and the horizontal plane, that is, the luminous elevation angle, can be obtained.

[0069] In addition, to avoid inaccurate calculation results of the luminous elevation angle due to the failure of the light intensity detection sensor 3, it is necessary to judge and exclude the faulty light intensity detection sensor 3. Therefore, a fault alarm module for the light intensity detection sensor 3 is set up. The specific judgment process is as follows:

[0070] The fault alarm module for the light intensity detection sensor 3 is used to judge whether the light intensity detection signals sent by two adjacent light intensity detection sensors 3 conform to the preset light intensity change standard; among them, the change trend of the light intensity detection signals of adjacent light intensity detection sensors 3 is obtained from the light intensity calculation formula. The theoretical ratio of the light intensity detection signals of adjacent light intensity detection sensors 3 is (d + c.cosα)2 / [(c + Δc).cosα + d]2, where Δc is the distance between two adjacent light intensity detection sensors 3. The light intensity change standard is to judge whether the error between the actual ratio of the light intensity detection signals detected by all adjacent light intensity detection sensors 3 and the theoretical ratio of the light intensity detection signals of adjacent light intensity detection sensors 3 is within the preset error value; if not, then control the alarm device coupled to the intelligent processing device 4 to issue an alarm, and send the information of the corresponding light intensity detection sensor 3 in the intelligent processing device 4 to the personnel for convenient maintenance by the personnel; on the contrary, if so, the luminous elevation angle is obtained normally; after obtaining the luminous elevation angle, the intelligent processing device 4 will display the luminous elevation angle of the lamp through a display coupled to the intelligent processing device 4 so that the personnel can understand the actual luminous elevation angle of the lamp.

[0071] At the same time, the prompt module 45 judges whether the difference between the luminous elevation angle of the lamp and the preset standard luminous elevation angle is within the preset numerical range; among them, the preset standard luminous elevation angle is the luminous elevation angle required to be adjusted in actual airport operations. If the difference between the luminous elevation angle of the lamp and the preset standard luminous elevation angle is not within the preset numerical range, then control the external prompt device to make a corresponding prompt, and the prompt device can be a speaker coupled to the intelligent processing device 4.

[0072] In addition, the intelligent processing device 4 is also coupled with a positioning sensor 5 for emitting positioning coordinate information. The intelligent processing device is wirelessly connected to a base station 6. The positioning sensor 5 is fixedly installed on the device body 1. The positioning sensor 5 can adopt an RTK high-precision positioning module. The base station 6 is used to obtain the elevation information of the lamp, that is, the distance between the positioning coordinate information and the standard coordinate plane, according to the built-in standard coordinate plane and the positioning coordinate information, and display it through a display screen, so that personnel can adjust the height index of the lamp.

[0073] The working principle of an adjustment device for optical calibration of approach navigation lights provided in this application is as follows: After personnel install this adjustment device for optical calibration of approach navigation lights on the approach navigation lights, the light emitted by the approach navigation lights passes through the light collecting port 12 and then obliquely irradiates onto the horizontal light collecting plate 21 due to the existence of the light elevation angle. Due to the oblique incidence, the distances traveled by the light rays irradiating onto the horizontal light collecting plate 21 from different positions of the light collecting port 12 are different, resulting in different light intensities on each light intensity detection sensor 3 on the horizontal light collecting plate 21. By substituting the standard light intensity detection signal and other light intensity detection signals into the light intensity calculation formula, the light elevation angle can be quickly obtained without manual measurement and verification by personnel, reducing the management pressure for calibrating temporary approach lights.

[0074] The above are only exemplary embodiments of the present disclosure and should not be used to limit the scope of the present disclosure. That is, any equivalent changes and modifications made in accordance with the teachings of the present disclosure still fall within the scope covered by the present disclosure. After considering the specification and the disclosure of the practical materials, those skilled in the art will easily think of other implementation schemes of the present disclosure. This application aims to cover any variations, uses or adaptive changes of the present disclosure, which follow the general principles of the present disclosure and include the common knowledge or conventional technical means in the technical field not recorded in the present disclosure.
