Description
Technical Field
[0001] The present application relates to the technical field of aircraft landing assistance devices, and in particular, to a control method, system, and medium for a self-positioning heliport navigation light. Background Art
[0002] With the application of unmanned aerial vehicles (UAVs) in fields such as logistics distribution and agricultural monitoring, the safety and reliability of their operations have attracted attention. However, in actual operations, UAVs may encounter emergencies such as navigation system failures or GPS signal losses, increasing the difficulty and risk of safe landing.
[0003] Currently, traditional heliport navigation light control systems are mainly designed for manned aircraft, and they usually rely on stable GPS signals and navigation data to provide guidance. However, due to the low flight altitude, complex flight paths, and higher environmental adaptability requirements of unmanned aerial vehicles, traditional navigation light control systems often cannot meet their special emergency landing needs; for example, in low-light environments or adverse weather conditions, existing navigation lights may not be able to provide sufficient visual guidance information.
[0004] The current safety and reliability of unmanned aerial vehicles in complex or emergency landing situations are insufficient. Specifically, in the face of sudden situations such as navigation system failures and GPS signal losses, there is a lack of effective auxiliary landing means, so there is an urgent need for improvement. Summary of the Invention
[0005] In order to improve the safety and reliability of unmanned aerial vehicles in complex or emergency landing situations, the present application provides a control method, system, and medium for a self-positioning heliport navigation light.
[0006] In a first aspect, the inventive purpose of the present application is achieved by adopting the following technical solutions:
[0007] A control method for a self-positioning heliport navigation light, comprising:
[0008] Obtaining environmental information, UAV status information, and navigation light layout information, and determining initial guidance parameters according to the environmental information, UAV status information, and navigation light layout information; the initial guidance parameters include the light brightness level, color mode, and working status of the direction indicator lights;
[0009] Calculating visual guidance signal parameters for each navigation light area based on the position of the UAV relative to each navigation light and the initial guidance parameters;
[0010] Determining a navigation light control scheme according to the visual guidance signal parameters and the initial guidance parameters, and sending a start lighting instruction to corresponding several navigation lights based on the navigation light control scheme;
[0011] Obtain environmental feedback information from each navigation aid light area, compare the environmental feedback information with the set value in the initial guidance parameters, and calculate the environmental difference value; if the environmental difference value exceeds the preset environmental change threshold range, trigger an environmental adaptability adjustment instruction;
[0012] Based on the environmental adaptability adjustment instruction, calculate the corresponding navigation aid light adjustment parameter and send an adjustment lighting instruction to the corresponding navigation aid light area.
[0013] By adopting the above technical solution, the environmental information includes light intensity and weather conditions; the UAV state information includes landing requirements, position coordinates, flight altitude and speed; the navigation aid light layout information includes the areas where each navigation aid light is located and their relative positions; the position status of the UAV relative to each navigation aid light includes distance and angle; the visual guidance signal parameters include but are not limited to the luminous intensity of the LEDs in each area, the color change mode, and the opening sequence of the direction indicators; specifically, to improve the visual guidance assistance of the navigation aid lights at the self-positioning heliport and provide an effective auxiliary landing means to meet the emergency landing requirements of the UAV, this application considers the characteristics of the helicopter navigation aid light control system including numerous navigation aid lights in multiple areas, provides a refined control method for the heliport navigation aid lights and a real-time monitoring method for the guidance effect of the navigation aid lights, and based on precise adjustment according to the specific situation of the UAV and environmental conditions, adopts a technical solution of dynamic adjustment through environmental adaptability adjustment instructions. Specifically, first obtain basic comprehensive information such as environmental information, UAV state information, and navigation aid light layout information, then calculate the visual guidance signal parameters for each navigation aid light area, considering that the navigation aid lights are distributed in multiple areas, ensure the coordinated operation between different areas to provide the best guidance effect, and at the same time, according to the current real-time position of the UAV, self-position and turn on several navigation aid lights in the corresponding area range for light guidance, so that all the navigation aid lights at the heliport work according to the predetermined navigation aid light control scheme. At the same time, to achieve the refined management of the multi-area navigation aid light control system, improve the lighting effect and control fineness of the navigation aid lights, this application will also obtain the environmental feedback information of each navigation aid light area in real time and calculate the environmental difference value. If it is found that the environmental difference value in any area exceeds the preset environmental change threshold range, then trigger the corresponding environmental adaptability adjustment instruction, and then, based on the environmental adaptability adjustment instruction, calculate the specific navigation aid light adjustment parameter for the affected navigation aid light area to further optimize the lighting conditions within the emergency docking range of the UAV to provide continuous and effective visual guidance.
[0014] In a preferred example of this application: The obtaining of environmental information, UAV state information, and navigation aid light layout information, and determining the initial guidance parameters according to the environmental information, UAV state information, and navigation aid light layout information specifically includes:
[0015] Extract the current light intensity and weather conditions from the environmental information;
[0016] Based on the position coordinates, flight altitude, and speed in the UAV status information, and combining the relative positions of each navigation light area in the navigation light layout information, determine the light brightness level of each navigation light area;
[0017] Based on the environmental information and UAV status information, determine the color mode and the working status of the direction indicator lights;
[0018] Associate the light brightness level, color mode, and the working status of the direction indicator lights to obtain the initial guidance parameters.
[0019] By adopting the above technical solution, based on different environmental parameters, dynamically adjust the working parameters of the navigation lights. For example, increase the light brightness level in low light or bad weather conditions to ensure that the UAV can clearly identify the navigation lights, so as to improve the environmental adaptability of the navigation lights at the heliport; when the UAV is in an emergency landing situation, to improve the safety and reliability of the unmanned aerial vehicle in complex or emergency landing situations, this application is based on the personalized configuration of the specific position and flight state of the UAV to ensure that at different distances and angles, the navigation lights in each area can provide the best visual guidance effect, improving the reliability and adaptability of the navigation light control system at the heliport; further, by dynamically adjusting the color mode (such as using high-contrast colors in emergencies) and the working status of the direction indicator lights (such as strengthening the indication in a specific direction), it is possible to provide more explicit landing guidance for the UAV in a complex environment and reduce the risk of misjudgment.
[0020] In a preferred example of this application: Based on the position status of the UAV relative to each navigation light and the initial guidance parameters, calculate the visual guidance signal parameters for each navigation light area, specifically including:
[0021] According to the relative distance and angle between the UAV and each navigation light area, calculate the LED luminous intensity within each navigation light area;
[0022] According to the relative distance and angle, and the color mode, determine the color change mode of each navigation light area;
[0023] According to the relative distance and angle, and the working status of the direction indicator lights, combined with the emergency landing speed of the UAV, determine the turning-on sequence and turning-on speed of the direction indicator lights;
[0024] Associate the LED luminous intensity, color change mode, turning-on sequence, and turning-on speed of the direction indicator lights to obtain the visual guidance signal parameters.
[0025] By adopting the above technical solution, the luminous intensity of several corresponding navigation light areas is dynamically adjusted according to the specific emergency landing position of the unmanned aerial vehicle (UAV) to generate accurate visual guidance signals; further, during the process of the UAV making an emergency landing in the landing area of the heliport, according to different approaching stages of the UAV, the color mode is adjusted in a timely manner to provide more intuitive guidance information for the UAV with a flexible color change mode. Through the calculation and adjustment of the turning-on sequence and turning-on speed of the direction indicator lights, a rapid response is made in the case of an emergency landing of the UAV, and the optimal visual guidance is provided.
[0026] In a preferred example of the present application: obtaining the environmental feedback information from each navigation light area, comparing the environmental feedback information with the set value in the initial guidance parameters, and calculating the environmental difference value; if the environmental difference value exceeds the preset environmental change threshold range, triggering an environmental adaptability adjustment instruction, which specifically includes:
[0027] According to the start lighting instruction, obtaining the environmental feedback information of each navigation light area to obtain the zoned environmental feedback information;
[0028] Obtaining the environmental change end information, and triggering a UAV position update instruction according to the environmental change end information;
[0029] Obtaining the UAV position update result information, and obtaining the current comprehensive status information of the specified position by combining the zoned environmental feedback information according to the UAV position update result information;
[0030] Calculating the environmental difference value according to the current comprehensive status information and the set value in the initial guidance parameters, in combination with the emergency landing speed of the UAV;
[0031] Comparing the environmental difference value with the preset environmental change threshold range; if the environmental difference value exceeds the preset environmental change threshold range, triggering an environmental adaptability adjustment instruction to the corresponding navigation light control terminal.
[0032] By adopting the above technical solution, based on the actual environmental conditions of each navigation aid light area under real-time monitoring, the environmental change situation is monitored. When the environment changes, the navigation aid light control system will automatically trigger a UAV position update instruction to obtain the latest UAV status information, the current position, flight altitude, and speed of the UAV. Then, the position information of the UAV and the environmental feedback information of each navigation aid light area are integrated to comprehensively evaluate the current comprehensive status information of the position (i.e., the designated position) for the UAV's emergency landing, so as to more accurately determine whether it is necessary to further adjust the navigation aid light control scheme. That is, by comparing the actual environmental status with the preset initial guiding parameters and combining the emergency landing speed of the UAV, the environmental difference value is accurately calculated, taking into account not only static environmental factors but also the influence of the dynamic flight state, improving the comprehensiveness and accuracy of the analysis of the lighting guiding effect of the navigation aid lights.
[0033] In a preferred example of the present application: Based on the environmental adaptability adjustment instruction, calculating the corresponding navigation aid light adjustment parameters and sending an adjustment lighting instruction to the corresponding navigation aid light area specifically includes:
[0034] According to the environmental adaptability adjustment instruction, obtaining navigation aid light adjustment parameter information, where the navigation aid light adjustment parameter information includes the LED light emission intensity adjustment value, color mode adjustment value, and direction indicator working state adjustment value within each navigation aid light area;
[0035] Comparing the LED light emission intensity adjustment value with a preset brightness threshold. If the LED light emission intensity adjustment value is less than the preset brightness threshold, then according to the navigation aid light adjustment parameter information and combining the emergency landing speed of the UAV, triggering an adjustment lighting instruction;
[0036] If the LED light emission intensity adjustment value is greater than the preset brightness threshold, then triggering a secondary adjustment instruction, and according to the secondary adjustment instruction, obtaining secondary adjustment parameter information;
[0037] According to the secondary adjustment parameter information, triggering an adjustment lighting instruction.
[0038] By adopting the above technical solution, detailed navigation light adjustment parameters are dynamically generated according to specific environmental changes. By setting a brightness threshold, the light brightness can be quickly increased when the lighting conditions are dim, ensuring that the navigation lights can still work effectively under low light or adverse weather conditions, and monitoring whether the current lighting brightness effect meets the preset lighting control effect. Since the navigation lights may experience light drift due to the LEDs in the navigation lights or be affected by the temperature environment during long-term operation, the lighting brightness control effect may deteriorate. Therefore, by setting a secondary monitoring and adjustment mechanism, when the initial adjustment fails to achieve the expected effect, the navigation light control system will automatically trigger a secondary adjustment command. The multi-level adjustment mechanism ensures that even in extreme cases, the navigation lights can gradually optimize their performance and provide continuous and reliable visual guidance.
[0039] In a preferred example of this application: Before obtaining the environmental information, the UAV status information, and the navigation light layout information, and determining the initial guidance parameters according to the environmental information, the UAV status information, and the navigation light layout information, the method further includes:
[0040] Obtain the installation information of the navigation light system and the design speed; wherein, the installation information of the navigation light system includes the installation height of the navigation light, the horizontal angle of the navigation light, the distance of the recognition range of the navigation light, and the distance between the recognition range of the navigation light and the landing area, and the design speed includes the design speed of the navigation light brightness, the first designed forced landing speed of the UAV, and the second designed forced landing speed of the UAV;
[0041] According to the first designed forced landing speed of the UAV, the horizontal angle of the navigation light, and the distance of the recognition range of the navigation light, judge the first predicted forced landing speed when the UAV enters the recognition range of the navigation light;
[0042] According to the installation type of the navigation light, the second designed forced landing speed of the UAV, the horizontal angle of the navigation light, and the distance between the recognition range of the navigation light and the landing area, judge the second predicted forced landing speed when the UAV passes through the landing area;
[0043] According to the design speed of the navigation light brightness, the first predicted forced landing speed, and the second predicted forced landing speed, generate a navigation light opening speed comparison table for controlling and adjusting the opening speed of the navigation light;
[0044] Obtain a reference range of the navigation light opening speed change representing the threshold of the navigation light opening speed change, and generate a navigation light opening speed control model according to the reference range of the navigation light opening speed change and the navigation light opening speed comparison table, where the navigation light opening speed control model is used to adjust the opening speed of the navigation light.
[0045] By adopting the above technical solution, based on the obtained detailed installation information and design speed parameters, an optimal working strategy is formulated according to the actual deployment situation, that is, the initial guidance parameters and the approach light control scheme; then, through accurate prediction of the landing speed, the first predicted landing speed when the UAV enters the approach light recognition range and the second predicted landing speed when the UAV passes through the landing area are predicted in advance to optimize the opening speed of several approach light control areas; by generating an approach light opening speed comparison table, it is convenient to dynamically adjust the opening speed of the approach light in a timely manner according to different landing speeds, ensuring the best visual guidance during the entire landing process and facilitating subsequent real-time adjustment of the opening speed of the approach light according to the speed change situation in actual operation.
[0046] In a preferred example of the present application: generating an approach light opening speed comparison table for comparing and adjusting the opening speed of the approach light according to the approach light brightness design speed, the first predicted landing speed, and the second predicted landing speed specifically includes:
[0047] Obtaining the predicted landing time according to the distance between the approach light recognition range and the landing area, the first predicted landing speed, and the second predicted landing speed;
[0048] Obtaining the designed landing time according to the first designed landing speed and the second designed landing speed;
[0049] Obtaining the predicted approach light opening speed according to the approach light brightness design speed, the predicted landing time, and the designed landing time;
[0050] Calculating the ratio of the first predicted landing speed to the second predicted landing speed to obtain a predicted landing speed ratio for predicting the second actual landing speed;
[0051] Calculating the difference in landing time between the predicted landing time and the designed landing time, and calculating the difference in opening speed between the predicted approach light opening speed and the approach light brightness design speed;
[0052] Obtaining a predicted opening speed time correspondence relationship for judging the actual opening speed of the approach light according to the difference in landing time and the difference in opening speed;
[0053] Generating an approach light opening speed comparison table for comparing and adjusting the opening speed of the approach light according to the predicted landing speed ratio and the predicted opening speed time correspondence relationship.
[0054] By adopting the above technical solutions, the predicted landing time is accurately calculated to plan the working mode of the navigation lights in advance, ensuring sufficient lighting support during critical periods; by comparing the actual predicted landing time with the designed landing time, it helps to evaluate whether the current operation meets the expectations and make timely adjustments; further, the predicted turning-on speed of the navigation lights is scientifically calculated to ensure appropriate light intensity at different stages and avoid excessive or insufficient lighting; through the detailed analysis of the difference between the landing time and the turning-on speed, the navigation light control system can more accurately judge the deviation of the current control operation; the corresponding relationship between the predicted turning-on speed and time is conducive to dynamically adjusting the turning-on speed of the navigation lights at different time periods; the finally generated speed comparison table provides a detailed operation guide for the system.

[0071] Figure 2 is a flowchart before step S1 in a control method for a self-positioning heliport navigation light in an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0072] The following further describes the present application in detail with reference to the accompanying drawings.
[0073] In one embodiment, as Figure 1 shown, the present application discloses a control method for a self-positioning heliport navigation light, which specifically includes the following steps:
[0074] S1: Obtain environmental information, UAV status information, and approach light layout information, and determine initial guidance parameters based on the environmental information, UAV status information, and approach light layout information; the initial guidance parameters include the light brightness level, color mode, and working status of the direction indicator lights.
[0075] In this embodiment, the environmental information includes light intensity, weather conditions (such as sunny, rainy, foggy, etc.), and wind speed; the UAV status information includes landing requirements, position coordinates, flight altitude, and flight speed; the approach light layout information includes the areas where each approach light is located, relative positions, installation heights, and horizontal heights. To facilitate the distinction of the numerous approach light areas and approach lights at the heliport, approach light identifiers and area identifiers can be associated with each approach light. For example, the areas are distinguished by Area A, Area B, and Area C, and the approach lights are distinguished by information codes; the position status of the UAV relative to each approach light includes distance and angle; the initial guidance parameters include the light brightness level, color mode, and working status of the direction indicator lights.
[0076] Specifically, obtain the current environmental information through sensors or external systems. For example, a light sensor is used to obtain the light intensity, a weather station provides weather conditions, and the status information of the UAV is obtained from the UAV's flight control system; adjust the light brightness level according to the light intensity in the environmental information; select a suitable color mode according to the weather conditions, such as using high-contrast colors under low-light conditions; set the working status of the direction indicator lights according to the flight direction of the UAV, and combine the calculated light brightness level, color mode, and working status of the direction indicator lights into the initial guidance parameters.
[0077] Further, step S1 specifically includes the following steps:
[0078] S11: Extract the current light intensity and weather conditions from the environmental information.
[0079] Specifically, the environmental information includes external condition data related to the operation of the approach lights; the light intensity refers to the light brightness level in the current environment.
[0080] S12: Determine the light brightness level of each approach light area according to the position coordinates, flight altitude, and speed in the UAV status information, in combination with the relative positions of the approach light areas in the approach light layout information.
[0081] Specifically, according to the flight parameters of the UAV that is about to land emergently, obtain the UAV status information, such as the speed and direction when approaching the landing area, and then dynamically adjust the light brightness levels of several approach light areas in the relevant areas according to the current status of the UAV and the approach light layout.
[0082] S13: Determine the color mode and the working status of the direction indicator lights according to the environmental information and the UAV status information.
[0083] Specifically, the color mode refers to the color configuration of the navigation lights. Multiple color modes are predefined and applicable to different environments and flight states. For example, when the visibility is poor in rain or fog, a cold color tone can be switched; the working state of the direction indicator light refers to a specific lighting mode used to indicate the landing direction of the UAV, which can be turned on or off according to the actual situation.
[0084] S14: Associate the light brightness level, color mode, and the working state of the direction indicator light to obtain the initial guidance parameters.
[0085] S2: Based on the position status of the UAV relative to each navigation light and the initial guidance parameters, calculate the visual guidance signal parameters for each navigation light area.
[0086] In this embodiment, the visual guidance signal parameters include, but are not limited to, the luminous intensity of the LEDs in each area, the color change mode, and the opening sequence of the direction indicator lights.
[0087] Specifically, step S2 specifically includes:
[0088] S21: Calculate the luminous intensity of the LEDs in each navigation light area according to the relative distance and angle between the UAV and each navigation light area.
[0089] S22: Determine the color change mode of each navigation light area according to the relative distance and angle, and the color mode.
[0090] Specifically, the color change mode refers to a color configuration that is dynamically adjusted according to the state of the UAV and environmental conditions to enhance the visual guidance effect; the color mode is a predefined set of color settings for different flight phases or environmental conditions of the UAV. The color mode can be set by different colors and color change frequencies. For example, the contrast can be increased in low light conditions, or a striking color combination can be used in case of an emergency. In practical applications, multiple color modes and corresponding color adjustment strategies can be predefined.
[0091] S23: Determine the opening sequence and opening speed of the direction indicator lights according to the relative distance and angle, and the working state of the direction indicator lights, in combination with the emergency landing speed of the UAV.
[0092] Specifically, the working state of the direction indicator light refers to whether the direction indicator light is on and its specific display mode; the opening sequence and speed of the direction indicator light are dynamically adjusted according to the state and flight path of the UAV. For example, when approaching the landing point, the flashing frequency of the indicator light is gradually increased to provide clear landing guidance.
[0093] S24: Associate the luminous intensity of the LEDs, the color change mode, the opening sequence, and the opening speed of the direction indicator lights to obtain the visual guidance signal parameters.
[0094] Specifically, the visual guidance signal parameters are a complete set of approach light operation parameters generated by integrating all relevant factors that control the approach lights and affect their lighting effects, including the LED luminous intensity, color change mode, and the opening sequence and speed of the direction indicator lights.
[0095] S3: Determine the approach light control scheme based on the visual guidance signal parameters and the initial guidance parameters, and send a start lighting instruction to the corresponding several approach lights based on the approach light control scheme.
[0096] In this embodiment, the approach light control scheme is a specific operation guide formulated based on the visual guidance signal parameters and the initial guidance parameters; the start lighting instruction is a specific operation command used to activate the approach lights.
[0097] S4: Obtain the environmental feedback information from each approach light area, compare the environmental feedback information with the set value in the initial guidance parameters, and calculate the environmental difference value; if the environmental difference value exceeds the preset environmental change threshold range, trigger an environmental adaptability adjustment instruction.
[0098] In this embodiment, the environmental difference value refers to the difference between the actual environmental information and the initial set value; the environmental change threshold range is the allowable environmental change range, and adjustment is required if the environmental change threshold range is exceeded.
[0099] Specifically, step S4 includes:
[0100] S41: Obtain the environmental feedback information from each approach light area according to the start lighting instruction to obtain the zoned environmental feedback information.
[0101] Specifically, the start lighting instruction is a specific operation command generated according to the control parameters of the approach light control scheme and is used to activate the approach lights. The zoned environmental feedback information refers to the actual environmental data collected by the sensors in each approach light area. For the purpose of facilitating the refined analysis of the landing area of a large helicopter airport by region, this application conducts one-to-one zoned differentiation and zoned identification based on each different approach light area to obtain the zoned environmental feedback information corresponding to each approach light area. For the purpose of easy distinction, the zoned environmental feedback information can be associated with the corresponding unique area location identifier.
[0102] In this embodiment, send a start lighting instruction to each approach light area to activate the approach light control system. The sensors in the approach light area start to work, collect the current environmental information in real time, and organize and classify the collected environmental information to form the zoned environmental feedback information.
[0103] S42: Obtain the environmental change end information, and trigger a UAV position update instruction according to the environmental change end information.
[0104] Specifically, the environmental change end information refers to the information indicating that the current environmental change has tended to be stable, which may come from sensors or external systems; the UAV position update instruction is a command used to update the current position coordinates and status information of the UAV.
[0105] S43: Obtain the UAV position update result information, and based on the UAV position update result information and combined with the partitioned environment feedback information, obtain the current comprehensive status information of the specified position.
[0106] Specifically, the UAV position update result information refers to the latest position coordinates and status information after the UAV is updated; the current comprehensive status information refers to the comprehensive evaluation result obtained by combining the UAV position and the environment feedback information.
[0107] S44: Calculate the environmental difference value according to the current comprehensive status information and the set value in the initial guidance parameters, in combination with the emergency landing speed of the UAV.
[0108] Specifically, the environmental difference value refers to the degree of difference between the actual environmental state and the set value of the initial guidance parameters; the emergency landing speed refers to the flight speed of the UAV in an emergency, which affects the requirements and effects of visual guidance.
[0109] For example, assume that the navigation aid light areas A, B, and C are located at different positions on the UAV landing path respectively:
[0110] Area A: The light intensity is 500 lux and the weather condition is light fog.
[0111] Area B: The light intensity is 3000 lux and the weather condition is medium fog.
[0112] Area C: The light intensity is 600 lux and the weather condition is medium fog.
[0113] Partitioned environment feedback information:
[0114] Area A: The light intensity is 500 lux, and the recommended brightness adjustment is 75%.
[0115] Area B: The light intensity is 300 lux, and the recommended brightness adjustment is 90%.
[0116] Area C: The light intensity is 600 lux, and the recommended brightness adjustment is 70%.
[0117] Initial guidance parameter set value:
[0118] Light intensity adaptation brightness: 80%; Color mode: High contrast mode; Direction indicator light flashing frequency: 2 times per second.
[0119] Based on the UAV position update instruction, the current position of the UAV is obtained: It is still 200 meters away from the landing point, with a flight altitude of 50 meters and a flight speed of 10 m / s.
[0120] Current comprehensive status information:
[0121] Area A: Brightness 75%, color mode high contrast, direction indicator flashing frequency 2 times per second.
[0122] Area B: Brightness 85%, color mode high contrast, direction indicator flashing frequency 2 times per second.
[0123] Area C: Brightness 70%, color mode high contrast, direction indicator flashing frequency 2 times per second.
[0124] Combining the new position of the UAV and the area environment feedback information, the calculated result is:
[0125] At 200 meters away from the landing point, stronger visual guidance is required.
[0126] The light intensity in Area B has been improved, but still requires a higher brightness.
[0127] S45: Compare the environmental difference value with the preset environmental change threshold range; if the environmental difference value exceeds the preset environmental change threshold range, trigger an environmental adaptability adjustment instruction to the corresponding navigation light control terminal.
[0128] For example, the preset environmental change threshold range is 5%, and the calculated result of the environmental difference value is:
[0129] Area A: Brightness difference = 80% - 75% = 5%;
[0130] Area B: Brightness difference = 80% - 85% = -5%;
[0131] Area C: Brightness difference = 80% - 70% = 10%.
[0132] Comparison result:
[0133] Area A: Brightness difference 5% (within the threshold range);
[0134] Area B: Brightness difference -5% (within the threshold range);
[0135] Area C: Brightness difference 10% (exceeds the threshold range).
[0136] Trigger the environmental adaptability adjustment instruction:
[0137] Area C: Since the brightness difference exceeds the threshold range, trigger the environmental adaptability adjustment instruction to adjust the brightness back to 80%.
[0138] S5: Based on the environmental adaptability adjustment instruction, calculate the corresponding navigation light adjustment parameters and send an adjustment lighting instruction to the corresponding navigation light area.

[0164] Calculation of the designed landing time:
[0165] The time from entering the recognition range to the landing area = 500 m / 10 m / s = 50 s.
[0166] Assume that an additional time (such as 15 s) is required for the deceleration process within the landing area, then the total designed landing time = 50 s + 15 s = 65 s.

[0179] Specifically, according to the difference in landing time and the difference in turn-on speed, establish a predicted turn-on speed-time correspondence; for example, if the difference in landing time is positive, the turn-on speed may need to be increased; otherwise, it is decreased.
