Energy-saving control method for aviation obstruction light based on environment perception and time period adaptation

Abstract

This invention discloses an energy-saving control method for aviation obstruction lights based on environmental perception and time-period adaptation, relating to the field of aviation obstruction light control technology. The invention pre-acquires the flight trajectories of several aircraft passing through a target area during the control period, fuses multiple flight trajectories to generate a covering spatiotemporal domain, and then determines the control time of the lighting cluster based on this covering spatiotemporal domain. Based on this, a control strategy including warning brightness and flashing frequency is generated to uniformly manage the aviation obstruction lights within the lighting cluster. This invention accurately defines the warning time period of the lights based on the covering spatiotemporal domain generated by the aircraft's flight trajectory. Normal warning mode is activated only when the aircraft passes through the target area and the lights need to perform their warning function; during non-warning periods, a low-frequency flashing mode can be entered. This fundamentally avoids the ineffective energy consumption problems of traditional photosensitive control, which is easily triggered by ambient light interference, and fixed-time control that ignores the actual passage of aircraft and continues to operate.

Description

Technical Field

[0001] This invention belongs to the field of aviation obstruction light control technology, specifically an energy-saving control method for aviation obstruction lights based on environmental perception and time-based adaptation. Background Technology

[0002] Aviation obstruction lights are specialized warning lights installed on tall buildings, iron towers, chimneys, bridges, and other tall structures to indicate the outline and location of obstacles to aircraft. Their core function is to indicate the position, height, and outline of tall buildings through lights with specified color, intensity, and flashing frequency in low-visibility environments such as night, cloudy days, fog, haze, rain, and snow, thus reminding aircraft to avoid obstacles and preventing flight collisions.

[0003] Most existing aviation obstruction light control solutions rely on single light detection to control the switching of aviation obstruction lights. For example, relying on photoresistors to detect ambient brightness is easily affected by fog, rain, twilight backlight, building lights, streetlights, etc., causing the lights to be falsely triggered and resulting in unnecessary energy consumption. Some solutions control the switching of aviation obstruction lights by preset switching time periods. This solution makes the light switching unable to adapt to seasonal and day-night changes. It still has unnecessary energy consumption in the process of light control and may also affect the warning effect of the lights.

[0004] This invention provides an energy-saving control method for aviation obstruction lights based on environmental perception and time-period adaptation to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes an energy-saving control method for aviation obstruction lights based on environmental perception and time-period adaptation.

[0006] To achieve the above objectives, a first aspect of the present invention provides an energy-saving control method for aviation obstruction lights based on environmental perception and time-period adaptation, comprising: The flight trajectories of several aircraft are fused in advance to generate a spatiotemporal domain covering the entire space-time domain; The aviation obstruction lights are divided into several light clusters; control times are set for several light clusters according to the coverage time and space domain. A control strategy for the lighting cluster is generated based on the control time, and several aviation obstruction lights in the lighting cluster are controlled based on the control strategy; wherein, the control strategy includes warning brightness and flashing frequency.

[0007] In one possible implementation, the flight trajectories of several aircraft are pre-fused, including: The flight trajectories of several aircraft passing through the target area during the control period are obtained in advance; the target area refers to the area where energy-saving control of aviation obstruction lights is required. During the control period, several flight trajectories are fused to generate a spatiotemporal domain that covers the entire space-time domain.

[0008] In one possible implementation, the aviation obstruction lights are divided into several light clusters, including: Aviation obstruction lights at the same height on the structure are grouped into a lighting cluster; Based on the spatiotemporal domain of the coverage, if it is determined that adjacent lighting clusters need to be controlled synchronously, the lighting clusters will be merged into one lighting cluster; otherwise, no merging process will be performed.

[0009] In one possible implementation, control time is set for several luminaire clusters based on the coverage spatiotemporal domain, including: The warning time for several light clusters is determined based on the coverage of the spatiotemporal domain; whereby the warning time refers to the time range within which the aviation obstruction lights in the light cluster need to play a warning role. The warning time is used as the control time for the corresponding lighting cluster.

[0010] In one possible implementation, the control time is adjusted by incorporating meteorological forecast data, including: The temporal visibility during the control period is predicted based on meteorological forecast data; the meteorological forecast data is obtained through a meteorological forecast platform. The required time for aviation obstruction lights is determined based on temporal visibility; where the required time is the period during which aviation obstruction lights are needed to serve a warning function, as determined from the perspective of weather conditions. Adjust the control time of the lighting cluster according to the required time.

[0011] In one possible implementation, determining the required timing of aviation obstruction lights based on temporal visibility includes: Identify the time range corresponding to visibility anomalies in time-series visibility data and mark it as an abnormal time range; where visibility anomalies are identified by a preset visibility threshold. The required time is determined based on the abnormal time range and the default time range within the control period; whereby the default time range refers to the time period within the control period during which the aviation obstruction lights are required to issue default warnings.

[0012] In one possible implementation, the control strategy for the lighting cluster is generated based on the control time, including: The warning brightness and flashing frequency of the lighting cluster are matched according to the warning time of the lighting cluster; whereby both the warning brightness and flashing frequency are obtained according to preset rules. A control strategy is generated based on the control time, warning brightness, and flashing frequency.

[0013] In one possible implementation, the control strategy is revised based on meteorological forecast data, including: Retrieve the abnormal time range; the abnormal time range is determined through meteorological forecast data. The flicker frequency within the abnormal time range is corrected based on the timing visibility to achieve the correction of the control strategy.

[0014] In one possible implementation, the flicker frequency within the abnormal time range is corrected based on temporal visibility, including: Match the flicker frequency corresponding to the abnormal time range in the control strategy; The flicker frequency is adjusted based on visibility within the abnormal time range to complete the correction of the control strategy.

[0015] In one possible implementation, the energy consumption of the lighting cluster during the control period is predicted according to the control strategy, and the energy storage device corresponding to the lighting cluster is replenished according to the energy consumption.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention pre-acquires the flight trajectories of several aircraft passing through the target area during the control period, and fuses multiple sets of flight trajectories to generate a covering spatiotemporal domain; then, it determines the control time of the lighting cluster based on the covering spatiotemporal domain, and generates a control strategy including warning brightness and flashing frequency based on this, and implements unified management and control of aviation obstruction lights within the lighting cluster; this invention accurately defines the warning time period of the lights based on the covering spatiotemporal domain generated by the aircraft's flight trajectory, and activates the normal warning mode only when the aircraft passes through the target area and the lights need to play a warning role, and can enter the low-frequency flashing mode during non-warning periods, thus fundamentally avoiding the ineffective energy consumption problems of traditional photosensitive control being easily triggered by ambient light interference and fixed-time control ignoring the actual passage of aircraft.

[0017] 2. After determining the initial control time of the lighting cluster based on the coverage spatiotemporal domain, this invention identifies the time range of abnormal visibility through meteorological forecast data, determines the required time by combining default warning periods such as nighttime, and corrects the control time of the lighting cluster using the required time. Simultaneously, it adapts and corrects the flashing frequency within this control time based on temporal visibility, ensuring that the correction parameters comply with aviation obstruction light industry standards and equipment parameter limits, ultimately forming an optimized control strategy that adapts to the meteorological environment. This invention breaks through the limitations of traditional control that relies solely on illumination or fixed time periods, using visibility as the core correction basis. It automatically supplements warning time during low visibility periods in the daytime and increases the flashing frequency in severe weather, compensating for the insufficient warning effect of conventional frequencies in environments such as fog, haze, rain, and snow. It addresses the safety warning needs of unreported aircraft while adapting to dynamic changes in seasons, day and night, and sudden weather events. Attached Figure Description

Detailed Implementation

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 The first aspect of this invention provides an energy-saving control method for aviation obstruction lights based on environmental perception and time-period adaptation, the implementation process of which is as follows: A01: The flight trajectories of several aircraft are fused in advance to generate a spatiotemporal domain covering the entire space-time domain; The spatiotemporal coverage domain is used to represent the spatial and temporal coverage range of several aircraft flight paths. This spatiotemporal coverage domain is the fundamental data for aviation obstruction light control, used to identify when aviation obstruction lights should issue warnings, thereby reducing unnecessary warning energy consumption.

[0022] The aircraft in this invention are not limited to a single type, but include all flight equipment that requires aviation obstruction lights for warning purposes. Aircraft include civil aircraft, helicopters, drones, etc., and their predetermined flight paths can be obtained through the corresponding monitoring platform.

[0023] A02: Divide the aviation obstruction lights into several light clusters; set control times for several light clusters according to the coverage time and space domain; To address the issue of insufficient warning effectiveness when aviation obstruction lights are used independently, this invention divides aviation obstruction lights into several light clusters. Synchronous control of the aviation obstruction lights within these clusters enhances the warning effect. Furthermore, control times are set for each cluster based on its coverage spatiotemporal domain, clearly defining the warning time for each aviation obstruction light within the cluster. This avoids unnecessary energy consumption during non-warning times, thereby reducing the overall energy consumption of aviation obstruction lights.

[0024] A03: Generate a control strategy for the lighting cluster based on the control time, and control several aviation obstruction lights in the lighting cluster based on the control strategy.

[0025] The control strategy mainly includes the warning brightness and flashing frequency of the lighting cluster during the corresponding warning time. Synchronizing the lighting cluster according to the control strategy can ensure that several aviation obstruction lights in the cluster flash synchronously to improve the warning effect on obstacles. During non-warning times, the aviation obstruction lights can be in a state of reduced energy consumption. The low-frequency flashing mode refers to the aviation warning lights being in a warning state with a low flashing frequency, and the flashing frequency in this state is preset.

[0026] This invention integrates the flight trajectories of several aircraft to obtain a coverage spatiotemporal domain. Based on this domain, it determines the control time for several lighting clusters, generates a control strategy, and synchronously controls several aviation obstruction lights within the clusters according to this strategy. This invention determines the control time of the lighting clusters based on the coverage spatiotemporal domain, providing a warning when aircraft pass by, but eliminating the need for warning when no aircraft are passing, thus reducing unnecessary energy consumption during aviation obstruction light operation. Furthermore, this invention divides several aviation obstruction lights into several lighting clusters, controlling these clusters as a whole to warn of the orderly outlines of structures, thereby ensuring the warning effect of the aviation obstruction lights.

[0027] Aviation obstruction lights are primarily used to warn aircraft of the outline and location of obstacles. Current solutions control these lights either by detecting light intensity or by pre-setting on / off time periods. Once the trigger condition is met, the obstruction lights remain on regardless of whether an aircraft is passing by, thus providing unnecessary warnings during periods when no aircraft are present.

[0028] This invention pre-acquires the flight trajectories of several aircraft, fuses these trajectories to obtain a covered spatiotemporal domain, and determines the warning time of aviation obstruction lights based on the covered spatiotemporal domain. This ensures that the aviation obstruction lights serve their warning function when aircraft pass by, and reduces energy consumption when no aircraft pass by, thus achieving energy-saving control of aviation obstruction lights.

[0029] The process for pre-fusing the flight trajectories of several aircraft in this invention is as follows: B01: Pre-acquire the flight trajectories of several aircraft passing through the target area during the control period; The control period is used to control aviation obstruction lights in different time periods. The future time is divided into several control periods. As the next control period approaches, the flight trajectories of several aircraft within that period are acquired, serving as the data basis for generating the spatiotemporal domain and formulating aviation obstruction light control strategies.

[0030] The target area refers to the area where energy-saving control of aviation obstruction lights is required. When an aircraft passes through, the aviation obstruction lights in this target area need to be activated to serve as a warning.

[0031] B02: During the control period, several flight trajectories are fused to generate a spatiotemporal domain covering the entire region.

[0032] To achieve energy-efficient control of aviation obstruction lights, it is necessary to clearly define the time and spatial range within which the lights are required to provide a warning effect. Based on this, a control strategy for the aviation obstruction lights can be designed to reduce energy consumption. This invention fuses the scattered flight trajectories of several aircraft within a control period, forming a spatiotemporal domain encompassing both temporal and three-dimensional spatial ranges.

[0033] When fusing several flight trajectories to obtain a covered spatiotemporal domain, the flight trajectories are first interpolated to achieve a continuous spatiotemporal curve. Interpolation methods include linear spatiotemporal interpolation, cubic spline spatiotemporal interpolation, etc.

[0034] By using a spatiotemporal fusion algorithm to fuse the interpolated flight trajectories, a covered spatiotemporal domain can be obtained. In this invention, a spatiotemporal grid overlay fusion algorithm can be used to fuse several flight trajectories. Specifically, the three-dimensional space of the target area is divided into several spatiotemporal grids (longitude × latitude × altitude). The interpolated flight trajectories are mapped to the corresponding spatiotemporal grids, and the occupied spatiotemporal grids are marked. A logical OR operation is performed on all marked grids, and all spatiotemporal grids traversed by the flight trajectories are merged to obtain the covered spatiotemporal domain corresponding to the several flight trajectories.

[0035] It should be noted that the coverage spatiotemporal domain incorporates the flight trajectories of several aircraft. Therefore, when controlling aviation obstruction lights based on the coverage spatiotemporal domain, the lights can simultaneously serve as warnings for multiple aircraft. Since the acquired flight trajectories are predetermined, if the actual flight trajectories change, the coverage spatiotemporal domain needs to be adjusted synchronously to ensure the accuracy of aviation obstruction light control.

[0036] For example, assuming the control period corresponds to a time range of one day (00:00-24:00), the flight trajectory is obtained from the aircraft's monitoring platform at 23:00 before the start time of the control period (00:00). Based on these flight trajectories, the time range in which the aircraft passes through the target area during the control period and the corresponding spatial range can be extracted. The time range and spatial range are then integrated into a spatiotemporal domain that covers the entire space-time domain.

[0037] If aviation obstruction lights are controlled independently, multiple aviation obstruction lights at the same height and on the same structure will flash at inconsistent rhythms, making it impossible to form a regular outline of the structure. This can easily cause pilots to misjudge the shape, height, and boundaries of the structure, posing a flight collision safety hazard.

[0038] This invention divides aviation obstruction lights into several light clusters. During actual control, the flashing frequency of the same light cluster can be used to form a complete outline of the structure, thereby eliminating safety hazards. The implementation process of dividing aviation obstruction lights into several light clusters in this invention is as follows: C01: Group aviation obstruction lights at the same height on a structure into a lighting cluster; The aviation obstruction lights at different heights on the structure are divided into different light clusters. If aviation obstruction lights at different heights on the structure need to serve a warning function simultaneously, they can be controlled synchronously. If aviation obstruction lights at a certain height on the structure need to serve a warning function, then the aviation obstruction lights at that height can be controlled synchronously, while the aviation obstruction lights at other heights enter a low-power warning state.

[0039] C02: Based on the coverage of the spatiotemporal domain, determine whether adjacent lighting clusters need to be controlled synchronously; if yes, merge the lighting clusters into one lighting cluster; otherwise, do not perform the merging process.

[0040] Synchronous control refers to the requirement that a cluster of lights must simultaneously provide an alert function, and the geographical distance between the clusters must be less than a preset distance threshold. Both conditions must be met simultaneously for a cluster of lights to be merged.

[0041] For example, suppose several aviation obstruction lights are installed at heights B1 and B2 on structure A1, corresponding to two light clusters. Similarly, several aviation obstruction lights are installed at height B1 on structure A2, corresponding to one light cluster. If, based on the coverage spatiotemporal domain, it is determined that the several aviation obstruction lights at height B1 on both structures A1 and A2 need to simultaneously serve a warning function, and the distance between structures A1 and A2 is less than a preset distance (e.g., <50m), it indicates that the same aircraft is passing through both structures A1 and A2 simultaneously. In this case, the several aviation obstruction lights at height B1 on both structures A1 and A2 are merged into one light cluster to synchronously control and display the orderly outline of the structures, thus improving the warning effect. If, based on the spatiotemporal domain of the coverage, it is determined that several aviation obstruction lights at heights B1 and B2 on structure A1 need to serve a warning function simultaneously, it means that both heights B1 and B2 of structure A1 will be within the field of view of aircraft, or that several aircraft will pass over structure A1 at the same time. In this case, the light clusters corresponding to heights B1 and B2 on structure A1 will be merged into one light cluster.

[0042] Whether adjacent light clusters need to provide a warning simultaneously depends on whether their warning times overlap. If there is an overlap, then they need to provide a warning simultaneously. For example, light cluster A and light cluster B each freely cover the warning time intervals generated in the spatiotemporal domain. ;like and If there is a time overlap, it means that both need to warn the aircraft at the same time, that is, they need to be controlled synchronously.

[0043] It should be noted that since the spatiotemporal domain of coverage is one of the determining factors in the division of lighting fixture clusters, the division results of lighting fixture clusters will be different in each control period. Therefore, after obtaining the spatiotemporal domain of coverage, it is necessary to update the lighting fixture clusters corresponding to the control period in a timely manner. In addition, since the spatial range of the spatiotemporal domain of coverage changes over time, the lighting fixture clusters will also be adjusted over time within the same control period.

[0044] This invention achieves regular contours at the same altitude and synchronized linkage across different altitudes within the same airspace, ensuring continuous and clear three-dimensional contours of obstacles and avoiding flight misjudgments caused by asynchronous layering; moreover, it only merges and highlights clusters that fall into the covered spatial and temporal domain, while maintaining low power consumption for clusters outside the domain, thereby reducing ineffective energy consumption from the perspective of spatial layering.

[0045] To achieve energy-saving control of aviation obstruction lights, it is necessary to define when the light clusters need to serve a warning function. The implementation process of this invention, which sets the control time for several light clusters based on their coverage spatiotemporal domain, is as follows: D01: Determine the warning time for several clusters of lights based on the coverage of the spatiotemporal domain; Warning time refers to the time range within which aviation obstruction lights in a cluster of lights need to serve a warning function. It can be defined as the time range within which the structure to which the cluster of lights belongs is within the aircraft's field of vision.

[0046] For example, if the spacecraft F is identified to pass through structure A1 within the control period from 20:00 to 20:10 based on the coverage of the spatiotemporal domain, and the lighting clusters at heights B1 and B2 in structure A1 need to serve as warnings simultaneously, then the lighting clusters at heights B1 and B2 are merged into one lighting cluster, and the warning time of the merged lighting cluster is from 20:00 to 20:10.

[0047] D02: Use the warning time as the control time for the corresponding lighting cluster.

[0048] As mentioned earlier, the determination of the control time mainly depends on the coverage spatiotemporal domain. That is, once an aircraft flies over the cluster of lights, the aviation obstruction lights in the cluster should be controlled to serve as a warning. However, the time range corresponding to the coverage spatiotemporal domain is the control period, which includes not only day and night, but also various meteorological conditions that may affect the warning effect.

[0049] Please see Figure 2 The implementation process of correcting the control time based on meteorological forecast data in this invention is as follows: E01: Based on meteorological forecast data, predict and obtain the temporal visibility during the control period, and determine the required time for aviation obstruction lights based on the temporal visibility. Meteorological forecast data can be obtained through a meteorological forecasting platform. Temporal visibility refers to the trend of visibility changes in the area where the lighting cluster is located under the influence of meteorological conditions. For example, hourly gridded visibility forecast products can be obtained from the meteorological forecasting platform, with a spatial resolution of 5km / 1km. Interpolation can be performed if necessary to obtain more refined temporal visibility. If the visibility is lower than a preset visibility threshold (e.g., 2km), it will affect the aircraft's field of vision, requiring the use of aviation obstruction lights to mark structures. If the visibility is not lower than the preset visibility threshold, it indicates that the field of vision is clear and aviation obstruction lights are not needed to mark structures.

[0050] Generally speaking, aviation obstruction light structures are required at night; if there are weather conditions such as fog, haze, rain, or snow during the day that affect the visibility of aircraft, aviation obstruction light structures are required; otherwise, aviation obstruction light structures are not required.

[0051] E02: Adjust the control time of the lighting cluster according to the required time.

[0052] The required time is determined based on weather conditions, while the control time is determined based on the airspace covered by the aircraft. If the light cluster is controlled solely based on the required time, aviation obstruction lights may be activated for warning purposes even when no aircraft are passing by; conversely, if the light cluster is controlled solely based on the control time, aviation obstruction lights may be activated for warning purposes even in clear weather. Both methods result in unnecessary energy consumption. This invention addresses these problems by modifying the control time based on the required time.

[0053] This invention adjusts the control time of the lighting cluster based on the demand time of aviation obstruction lights. If a portion of the demand time falls during the day and the visibility is abnormal during that time, that time period should also be used as the control time for the lighting cluster. In this way, the aviation obstruction lights can serve as a warning during the day when visibility is low, ensuring the safe passage of aircraft even in low daytime visibility conditions.

[0054] The required time period is the time during which aviation obstruction lights need to serve their warning function, determined from a weather and operational condition perspective. It is primarily based on daytime, nighttime, and visibility to determine the required time for aviation obstruction lights within the control period. The implementation process of this invention for determining the required time of aviation obstruction lights based on time-series visibility is as follows: F01: Identify the time range corresponding to visibility anomalies in the time-series visibility data and mark it as an abnormal time range; whereby visibility anomalies are identified through a preset visibility threshold. F02: Determine the required time based on the abnormal time range and the default time range within the control period.

[0055] The default time range refers to the time period during which aviation obstruction lights are required to be on by default within the control period. For example, the nighttime period within the control period falls within the default time period during which aviation obstruction lights need to be on, meaning that aviation obstruction lights need to be turned on at night. Furthermore, aviation obstruction lights are required to be on even during the day within the airport area; therefore, the default time within the control period also needs to be determined comprehensively based on the location of the aviation obstruction lights within the light cluster.

[0056] For example, suppose the control time determined based on the warning time is [(8:00, 9:00), (19:00, 20:00), (22:00, 24:00)], meaning that aircraft will pass over the light cluster during these three time periods; the demand time is [(8:00, 9:00), (17:00, 18:00), (19:00, 24:00)], where (19:00, 24:00) falls within the nighttime range of the control period, and (8:00, 9:00, 19:00, 19:00, 20:00)... The time ranges (9:00), (17:00, 18:00) fall within the daytime range of abnormal visibility. At the same time, aircraft will pass over the light cluster during the time period (8:00, 9:00). There is an overlap between the time periods (22:00, 24:00) and (19:00, 24:00) (22:00, 24:00). Therefore, the control time is corrected to [(8:00, 9:00), (19:00, 20:00), (22:00, 24:00)].

[0057] It should be noted that this invention achieves aviation obstruction light control based on the accurate acquisition of aircraft flight trajectories. Considering the possibility of unreported aircraft, in order to ensure the safe flight of these aircraft, the control time is modified with the required time as the core data. Referring to the previous example, the control time can be modified to [(8:00, 9:00), (17:00, 18:00), (19:00, 24:00)]. In this way, when visibility is abnormal during the day, the aviation obstruction lights are controlled to issue a warning regardless of whether an aircraft is detected passing by. During the night, the aviation obstruction lights are continuously turned on to issue a warning.

[0058] As mentioned earlier, the control time of the lighting cluster is used to determine the warning time of the lighting cluster. In order to reduce the energy consumption of aviation obstruction lights, this invention determines the control strategy based on the warning time to ensure that the aviation obstruction lights in the lighting cluster reduce energy consumption while maintaining their warning function.

[0059] The implementation process of the control strategy for generating lighting clusters based on control time in this invention is as follows: G01: Match the warning brightness and flashing frequency of the lighting cluster according to the warning time of the lighting cluster; where the warning brightness and flashing frequency are obtained according to preset rules; G02: Generates a control strategy based on control time, warning brightness, and flashing frequency.

[0060] Different models of aviation obstruction lights are selected based on the installation height, and the aviation obstruction lights installed at different heights within the same structure are also different. Each aviation obstruction light is preset with different warning brightness and flashing frequency for different times to ensure the warning effect during the day while avoiding disturbance to residents at night.

[0061] The warning time is divided into different time periods based on daytime and nighttime. If the time period belongs to daytime, the warning brightness and flashing frequency are matched to the daytime setting; if the time period belongs to nighttime, the warning brightness and flashing frequency are matched to the nighttime setting. In some other preferred embodiments, dusk can also be set in addition to daytime and nighttime to further refine the control of the lighting cluster.

[0062] The parameters of existing aviation obstruction lights vary depending on the height of the structure to which they are applied. Aviation obstruction lights for super high-rise structures (height > 150m) include three basic brightness levels with a flashing frequency of 40-60 times / minute, corresponding to daytime (200,000cd), dawn / dusk (20,000cd), and nighttime (2,000cd) levels, respectively. The daytime level has the highest brightness, and the nighttime level has the lowest brightness. Aviation obstruction lights for mid- to high-rise structures (height between 45-150m) generally include two basic brightness levels with a flashing frequency of 20-60 times / minute, corresponding to daytime (20,000cd) and nighttime (2,000cd) levels, respectively. Ordinary structures (height < 45m) can be set to one basic brightness level, which can be kept constantly lit.

[0063] When matching warning brightness and flashing frequency to a cluster of lights based on the warning time, the warning time is first divided according to the preset range of the aviation obstruction lights, and then the warning brightness and flashing frequency are matched separately. Taking the aviation obstruction lights of a super high-rise building as an example, the warning time of the light cluster is divided into daytime, dawn / dusk and nighttime, and preset base brightness and flashing frequency are matched for daytime, dawn / dusk and nighttime respectively.

[0064] If a cluster of lights includes aviation obstruction lights at different altitudes, each should have a different warning brightness, but a unified flashing frequency (if possible). For example, if the flashing frequency of high-altitude aviation obstruction lights is 40-60 times per minute, and the flashing frequencies of mid-altitude and low-altitude aviation obstruction lights are 20-60 times per minute, then the flashing frequency of the entire cluster should be set to 40 times per minute, meaning the aviation obstruction lights in the cluster should be controlled at 40 flashes per minute.

[0065] Aviation obstruction lights are easily affected by extreme environments during the warning process. Once visibility decreases, the warning brightness and flashing frequency matched to the warning time may fail to play a warning role, which in turn makes it difficult for aircraft to effectively avoid obstacles in extreme environments.

[0066] Please see Figure 3 The implementation process of the control strategy based on meteorological forecast data in this invention is as follows: H01: Retrieve the abnormal time range; The abnormal time range is the same as that mentioned above, which is the time range corresponding to the visibility anomaly identified based on the time-series visibility.

[0067] H02: Correct the flicker frequency within the abnormal time range based on the timing visibility to achieve the correction of the control strategy.

[0068] When modifying the control strategy, the main focus is on adjusting the flashing frequency. If the visibility is abnormal during a certain period of the control time, the warning effect will be reduced when the warning is issued according to the preset flashing frequency. Therefore, the flashing frequency is adjusted according to the temporal visibility to ensure the warning effect in harsh environments.

[0069] Because the parameters of aviation obstruction lights need to meet industry standards, their flashing frequencies must all fall within a preset range. This invention adjusts the flashing frequency according to a preset correction ratio. The implementation process for correcting the flashing frequency within an abnormal time range based on temporal visibility is as follows: I01: Match the flicker frequency corresponding to the abnormal time range in the control strategy; I02: Adjust the flicker frequency based on visibility within the abnormal time range to complete the correction of the control strategy.

[0070] The correction ratio in this invention refers to the correction step size of the flicker frequency. For example, if the correction step size of the flicker frequency is 5 times / minute, then the flicker frequency will be increased by 5 times / minute to complete the correction.

[0071] The correction of the flashing frequency should be constrained by the parameters of the aviation obstruction light itself, that is, the flashing frequency should not exceed the maximum flashing frequency corresponding to the aviation obstruction light.

[0072] For example, suppose the warning brightness and flashing frequency corresponding to the abnormal time range (belonging to the nighttime time range) in the control strategy are as follows: the warning brightness of the high-rise obstruction light and the mid-level obstruction light are both at the nighttime level (2000cd), and the flashing frequency is set to 40 times / minute. Since the visibility is abnormal in the abnormal time range, it is necessary to improve the warning effect. Therefore, the flashing frequency can be corrected according to the preset correction ratio, such as increasing the flashing frequency by 10 times / minute, correcting it to 50 times / minute.

[0073] It should be noted that the corrected flashing frequency is faster. However, if the flashing frequency within the abnormal time range is already the highest value for the aviation obstruction light, then no correction is needed.

[0074] After clarifying the control strategy during the control period, the energy consumption of the lighting cluster during the control period can be predicted. Based on this energy consumption, the energy storage equipment of the lighting cluster can be replenished. This can ensure that the energy storage equipment can ensure that the aviation obstruction lights can perform their warning function while reducing the energy storage, thereby reducing the energy storage cost.

[0075] It should be noted that redundancy should be considered when replenishing energy, meaning the actual replenished energy should be greater than the energy consumed during the control period, to avoid energy shortages due to unforeseen circumstances. Also, aviation obstruction lights can operate in low-frequency flashing mode during non-control periods, and the energy consumption during these non-control periods needs to be considered when predicting energy consumption.
