Description

Technical Field

[0001] The present invention relates to the technical field of light group control, and in particular to a LED light group control system based on MESH networking. Background Art

[0002] As people's awareness of ecological environmental protection increases, migratory birds, as an important part of the ecosystem, are increasingly valued for their protection. During their migration, migratory birds are affected by various environmental factors, among which the interference of artificial light sources is an important aspect. Different species of migratory birds have different sensitivities to light. Improper lighting may cause the migratory birds to deviate from their migration paths, abnormal stay time, and other problems, affecting their normal migration and survival. Therefore, an LED light group control system based on MESH networking is needed.

[0003] Prior art, such as the invention application patent with announcement number: CN110446304A, discloses a cluster control system of urban LED landscape lights based on FPGA, including a power supply, a rectifier, a plurality of LED lights, a light adjustment module and a light switch module, wherein the power supply, the rectifier and the plurality of LED lights are electrically connected in sequence; the plurality of LED lights, the light adjustment module and the light switch module are electrically connected, and the light switch module is connected to a cluster control system, which is mainly composed of a sensing unit and an active control unit. The present invention relates to the field of LED landscape light technology. This technical solution provides an inductive control system that can realize active and automatic control. In this technical solution, light effect files can be written according to the needs of the demander, stored through a storage module, read and written using an FPGA module, and centrally controlled through a PC host computer and a capacitive touch screen.

[0004] In view of the above scheme, the inventors of the present application have found that the above technology has at least the following technical problems: 1. The existing technology often does not fully consider the factors of migratory bird migration when controlling LED light groups. It is just purely from the perspective of lighting needs, and there is no differentiated setting for the light sensitivity characteristics of different migratory bird species, which causes the lights to interfere with the navigation, roosting and other behaviors of migratory birds, affecting the normal migration and survival of migratory birds, and causing adverse effects on the ecological environment. At the same time, the existing LED light group control system may only be able to adjust the lighting parameters according to a single or a few factors (such as time, simple ambient brightness, etc.). It is impossible to comprehensively consider multiple adjustment influencing indicators such as natural light intensity, peak traffic flow, and the number of various types of special events like this solution. It is difficult to achieve accurate, dynamic and intelligent control of the light group, and it is impossible to provide the best lighting effect in different scenarios, resulting in energy waste or insufficient lighting.

[0005] 2. Existing technologies lack effective emergency response mechanisms when faced with emergencies or when they have adverse effects on the ecological environment. There is no reasonable monitoring time point and evaluation method to determine whether it is necessary to activate the emergency protection mode, and there are no complete early warning and linkage measures. When the lighting of the LED light cluster has a significant impact on ecological factors such as migratory birds, timely measures cannot be taken to adjust and protect them, and the stability and safety of the ecosystem cannot be guaranteed. At the same time, the existing LED light cluster control system may have problems such as unstable communication and poor networking flexibility. Traditional communication methods may be easily interfered with or attenuated in complex environments, resulting in poor transmission of light cluster control commands and affecting the normal operation of the system. Moreover, when large-scale light clusters are deployed, the scalability and adaptability of traditional networking methods are poor, and it is difficult to meet the needs of actual applications.

[0006] 3. Existing technologies may not fully utilize environmental data and light cluster operation data for in-depth analysis. It is impossible to mine and analyze a large amount of data to establish an accurate model to optimize the control strategy of the light cluster, and it is difficult to continuously improve the performance and effect of the system, and it is impossible to achieve continuous improvement and intelligent upgrade of the system. Summary of the invention

[0007] In view of the above-mentioned technical deficiencies, an object of the present invention is to provide an LED light group control system based on MESH networking.

[0008] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an LED light group control system based on MESH networking, including: an adjustment influence factor analysis module: used to obtain the adjustment influence index corresponding to the current time period in the target area, so as to analyze and obtain the adjustment influence factor corresponding to the current time period in the target area.

[0009] Migratory bird migration analysis module: used to obtain the migratory bird species corresponding to the current time period in the target area, so as to obtain the optical prohibition index collection corresponding to various types of migratory birds in the current time period in the target area, and then analyze and obtain the optical prohibition adaptation value corresponding to the current time period in the target area.

[0010] Optical light group control module: used to analyze the optical sensitivity level corresponding to the current time period in the target area according to the optical disabling adaptation value corresponding to the current time period in the target area, and then analyze the light group optical control parameter adjustment value corresponding to the current time period in the target area.

[0011] Emergency protection mode evaluation module: It is used to set several monitoring time points after the current time period in the target area is adjusted according to the corresponding light group optical control parameter adjustment value, and then evaluate whether the light group in the current time period in the target area at each monitoring time point needs to enter the emergency protection mode.

[0012] The beneficial effects of the present invention are as follows: 1. In the embodiment of the present invention, the migratory bird species are obtained through the migratory bird migration analysis module, the optical disabled index collection and the adaptation value are determined, and then the optical light group control module adjusts the light group parameters according to the adaptation value. In this way, the light emitted by the LED light group can effectively avoid interfering with the navigation, habitat and migration of migratory birds, reduce the problems of lost direction and excessive energy consumption caused by light pollution, and protect the survival and reproduction of migratory birds. For example, migratory birds can be prevented from being attracted by lights and deviating from the normal migration route, and the risk of collision with buildings, wires, etc. can be reduced. Migratory birds play an important role in the ecosystem, such as spreading seeds and controlling the number of pests. The protection of migratory birds by the system helps to maintain the biodiversity and ecological balance of the ecosystem and promote the healthy development of the entire ecological environment. The adjustment influence factor analysis module comprehensively considers the adjustment influence indicators such as natural light intensity, peak traffic flow and number of special events, analyzes the adjustment influence factors, and provides a basis for adjusting the optical control parameters of the light group. This enables the LED light group to accurately adjust the light according to the actual environmental requirements and avoid unnecessary energy waste. For example, reduce the brightness of the light cluster when there is sufficient natural light, and reduce the lighting power when traffic flow is low. By reasonably adjusting the brightness, color temperature and other parameters of the light cluster, we can reduce the excessive use and frequent flashing of lamps, reduce the loss of lamps, thereby extending the service life of lamps, reducing the cost of lamp replacement and waste emissions to the environment.

[0013] 2. In the embodiment of the present invention, the various modules of the scheme work together to realize the automatic and intelligent control of the LED light group. Without manual intervention, the light group parameters can be automatically adjusted according to different time periods, environmental conditions and migratory bird migration conditions, thereby improving the efficiency and accuracy of lighting management. The scheme not only takes into account the migratory bird protection factors, but also integrates a variety of adjustment influencing indicators such as natural light, traffic flow and special events. It can meet the needs of ecological protection while taking into account the lighting needs of human activities, thus realizing the organic combination of ecological protection and urban lighting management. At the same time, the emergency protection mode evaluation module sets the monitoring time point to monitor and evaluate the effect of the light group after adjustment in real time. Once it is found that the light group has an adverse effect on migratory birds and the emergency protection mode is required, an early warning can be issued in time and corresponding measures can be taken to ensure the reliability and stability of the system. At the same time, the scheme accumulates a large amount of environmental data, migratory bird migration data and light group control parameter data during operation. By analyzing and mining these data, the control strategy and algorithm of the system can be further optimized to improve the performance and adaptability of the system.

[0014] 3. In the embodiment of the present invention, when the system evaluates that an emergency protection mode is required, it can quickly start the local sound and light alarm, push alarm information to the operation and maintenance terminal, notify management personnel by text message or email, etc., and at the same time link the environmental monitoring system and the traffic management system to take measures such as reducing the surrounding illumination to protect migratory birds in time and reduce losses. At the same time, the historical parameter library and the digital twin model are automatically retrieved to generate candidate solutions, providing a scientific basis and decision-making support for emergency handling, and improving the efficiency and effectiveness of emergency handling. In addition, all warning events are synchronously generated as encrypted files to facilitate subsequent analysis and summary, and provide a reference for improving the system and dealing with similar situations.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] Adjustment impact factor analysis module: used to obtain the adjustment impact index corresponding to the current time period in the target area, so as to analyze and obtain the adjustment impact factor corresponding to the current time period in the target area.

[0021] In a specific embodiment, the analysis obtains the adjustment impact factor corresponding to the current time period in the target area. The specific analysis process is as follows: the adjustment impact index corresponding to the current time period in the target area is obtained, and the adjustment impact index includes the natural light intensity, the peak traffic flow and the number corresponding to each type of special event. The natural light intensity, the peak traffic flow and the number corresponding to each type of special event in the current time period in the target area are used as input items, and are imported into the adjustment impact factor analysis model. After the calculation and analysis of the adjustment impact factor analysis model, the adjustment impact factor corresponding to the current time period in the target area is finally output, and the adjustment impact factor corresponding to the current time period in the target area is recorded as .

[0022] It should be noted that by deploying light sensors such as photoresistors and silicon photodiodes in the target area, the ambient light data is collected in real time, and the sensor error is corrected in combination with the data of the sun altitude angle and cloud coverage rate from the meteorological station. The sensors need to be evenly distributed in unobstructed locations such as lamp poles and building high points, and calibrated regularly to ensure data accuracy, so as to reflect the changes in natural light in real time.

Through real-time monitoring and dynamic prediction, the peak traffic flow in the current period is accurately captured. Integrate official government platforms, social media NLP keyword analysis, such as "concert" and "marathon", ticketing system API data, and cross-verify the location and time of the event. At the same time, combined with abnormal traffic flow fluctuation analysis, dynamic identification of unrecorded temporary events to ensure the comprehensiveness and timeliness of the number of special events.

[0023] Migratory bird migration analysis module: used to obtain the migratory bird species corresponding to the current time period in the target area, so as to obtain the optical prohibition index collection corresponding to various types of migratory birds in the current time period in the target area, and then analyze and obtain the optical prohibition adaptation value corresponding to the current time period in the target area.

[0024] In a specific embodiment, the optical prohibition indicator collection corresponding to various types of migratory birds in the current time period in the target area is obtained, and the specific obtaining process is as follows: obtain the migratory bird species corresponding to the current time period in the target area, and compare the various types of migratory birds corresponding to the current time period in the target area with the types of migratory birds corresponding to each optical prohibition indicator collection in the migratory bird light sensitivity parameter library; if a type of migratory bird corresponding to the current time period in the target area is the same as a type of migratory bird corresponding to a certain optical prohibition indicator collection in the migratory bird light sensitivity parameter library, then the optical prohibition indicator collection in the migratory bird light sensitivity parameter library is used as the optical prohibition indicator collection corresponding to the type of migratory bird, and the optical prohibition indicator collection includes a spectral sensitivity range, a critical light intensity, and a flicker frequency sensitivity range.

[0025] It should be noted that the migratory bird light sensitivity parameter library is used to store the migratory bird species corresponding to each optical prohibition indicator collection.

[0026] In a specific embodiment, the analysis obtains the optical disabling adaptation value corresponding to the current time period in the target area. The specific analysis process is as follows: the spectral sensitivity interval, critical light intensity and flicker frequency sensitivity range corresponding to various types of migratory birds in the current time period in the target area are recorded as , and , where h represents the number of each type of migratory bird. , a is any integer greater than 2, substitute it into the calculation formula: The optical disable adaptation value corresponding to the current time period in the target area is obtained. ,in, , , They are the standard spectral sensitivity range, standard critical light intensity, and standard flicker frequency sensitivity range corresponding to various types of migratory birds. , , They are the weight factors corresponding to the spectral sensitivity ranges of various migratory birds, the weight factors corresponding to the critical light intensity, and the weight factors corresponding to the flicker frequency sensitivity range. Represents a natural constant.

[0027] It should be noted that , , Both are greater than 0 and less than 1.

[0028] It should also be noted that it is determined through multi-dimensional experiments and data modeling. The spectral sensitivity range is determined by analyzing the absorption spectrum of migratory bird retinal photoreceptor cells, such as measuring visual protein gene expression through a spectrophotometer, combining laboratory spectral irradiation experiments, recording the behavioral responses of migratory birds under monochromatic light, and referring to the International Commission on Illumination (CIE) photobiological safety standards to divide sensitive bands; the critical light intensity I_h0 is determined by field control experiments, monitoring the deviation rate of migratory bird migration paths under different light gradients, such as using GPS trackers to record individual trajectories and determine the minimum threshold that causes a deviation of more than 5%; the flicker frequency sensitivity range F_h0 is determined by recording the pupil contraction frequency of migratory birds to light stimuli of different frequencies with a high-speed camera, such as using eye tracking Technology, combined with its visual persistence characteristics, measured retinal responses through electrophysiological experiments, and obtained critical frequency ranges, eventually forming a species-specific standardized parameter library, and using the analytic hierarchy process to construct a judgment matrix. Ecologists, ornithologists, and lighting engineers were invited to compare the ecological impacts of spectrum, intensity, and frequency, and calculate the initial weight values. Secondly, combined with the endangered level of migratory birds, such as the IUCN Red List, revisions were made to increase the spectral weights of critically endangered species (w_S ≥ 0.5). Finally, through machine learning algorithms, such as gradient boosting trees, historical monitoring data were analyzed, and the changing trend of the abnormal activity rate of migratory birds under different weight combinations was inferred, and the weight distribution was dynamically optimized.

[0033] S3. If the optical sensitivity level corresponding to the current time period in the target area is a high sensitivity level, the optical brightness of the light group corresponding to the security light group will be reduced by 50%-60% on the basic brightness, the brightness of the traffic light will be increased to 130-150cd / m², the brightness of the emergency evacuation light will remain unchanged, the color temperature will be reduced to 2200-2500K, only the red light band of 600-780nm will be retained, and the visible light spectrum in the range of 400-580nm will be removed. The flashing frequency of traffic lights will be reduced to 0.2-0.6 times / second, and the flashing frequency of emergency evacuation lights will be increased to 1.5-2 times / second when a disaster occurs, and they will remain on at other times.

[0035] Emergency protection mode evaluation module: It is used to set several monitoring time points after the current time period in the target area is adjusted according to the corresponding light group optical control parameter adjustment value, and then evaluate whether the light group in the current time period in the target area at each monitoring time point needs to enter the emergency protection mode.

[0036] In a specific embodiment, the emergency protection mode evaluation module further includes a lamp group evaluation index acquisition unit.

[0037] The light group evaluation index acquisition unit is used to set a number of monitoring time points after the current time period in the target area is adjusted according to the corresponding light group optical control parameter adjustment value, and then obtain the ecological benefit data corresponding to the light group in the current time period in the target area at each monitoring time point. The ecological benefit data includes the migration path deviation rate and residence time change rate corresponding to various types of migratory birds.

[0038] It should be noted that by deploying high-frequency migratory bird tracking equipment, such as micro GPS / Beidou locators and radar monitoring stations, the migration trajectory data of migratory birds in the target area is collected in real time. Combined with the historical standard migration path database of the same period, the dynamic time warping algorithm is used to calculate the similarity between the real-time path and the standard path, and then the deviation index is generated. At the same time, machine learning models, such as LSTM neural networks, are introduced to identify abnormal deviation behaviors and eliminate interference from natural environmental factors. Finally, the migration path deviation rate of different types of migratory birds at each monitoring time point is obtained. An intelligent monitoring network is set up in the target area, such as infrared thermal imaging cameras and acoustic sensor arrays. Combined with computer vision technology, YOLO target detection + DeepSORT multi-target tracking, the stay time of individual migratory birds is counted in real time. By comparing the stay data at the same monitoring time point before and after the adjustment, the double-sample KS test is used to analyze the significant changes in the distribution of stay time, and the change rate is calculated: ΔT%=[(T_after adjustment-T_before adjustment) / T_before adjustment]×100%). For migratory birds during the migratory and non-migratory periods, baseline models need to be established separately, such as seasonal ARIMA models, to predict the residence time under natural conditions.

[0039] In a specific embodiment, the evaluation of whether the light clusters in the current time period in the target area at each monitoring time point need to enter the emergency protection mode is performed as follows: the migration path deviation rates and residence time change rates corresponding to various types of migratory birds in the light clusters in the current time period in the target area at each monitoring time point are accumulated respectively, and then the total migratory bird migration path deviation rate and the total migratory bird residence time change rate corresponding to the light clusters in the current time period in the target area at each monitoring time point are obtained, and the total migratory bird migration path deviation rate and the total migratory bird residence time change rate corresponding to the light clusters in the current time period in the target area at each monitoring time point are compared with the set standard total migratory bird migration path deviation rate and the standard total migratory bird residence time change rate respectively. For comparison, if the total migratory bird migration path deviation rate and the total migratory bird residence time change rate corresponding to the light group in the target area at a certain monitoring time point in the current time period are less than or equal to the set standard total migratory bird migration path deviation rate and standard total migratory bird residence time change rate, then it is assessed that the light group in the target area at the current time period does not need to enter the emergency protection mode; if any of the total migratory bird migration path deviation rate and the total migratory bird residence time change rate corresponding to the light group in the target area at a certain monitoring time point in the current time period is greater than the set standard total migratory bird migration path deviation rate and standard total migratory bird residence time change rate, then it is assessed that the light group in the target area at the current time period needs to enter the emergency protection mode.

[0040] It should be noted that the emergency protection mode includes traffic coordination: linking the traffic management system to reduce the surrounding illumination by 10%-20% (within a specific area radius of 3 kilometers), environmental monitoring: synchronizing meteorological data (triggering enhanced response when wind speed>10m / s and visibility<500 meters), ecological protection: sending abnormal activity coordinates of migratory birds to the wildlife protection platform (latitude and longitude accuracy 0.001°) Intelligent decision support: calling the digital twin model to generate 3 sets of candidate solutions; Plan 1: Regional dimming + spectrum optimization implementation parameters, closed area: all landscape ecological lighting groups are closed, and non-essential areas for production operations are closed (closing rate 70%), illumination adjustment: the brightness of safety and security lighting groups is reduced to 50% of the basic value (another 10% reduction on the basis of the original adjustment value), spectrum control: only retaining the 600-780nm red light band, and the blue light band intensity is reduced to 0, flashing frequency: the flashing frequency of traffic lights is reduced from 0.6Hz to 0.3Hz, Plan 2: full infrared conversion + Dynamic frequency control, spectrum conversion: all light groups switch to 780-900nm infrared spectrum (including safety protection type), illumination control: basic brightness is maintained at 60% (achieved through infrared LED), flicker management: the flashing frequency of emergency evacuation lights is reduced from 1.5Hz to 0.5Hz, linkage measures: the traffic management system simultaneously switches the surrounding road lighting to infrared mode; Plan 3: Gradual and regional enhanced control, core area (radius 500 meters): all lighting is turned off, only emergency evacuation lights (infrared mode) are retained, buffer zone (500-1500 meters): brightness is reduced to 30% of the basic value, color temperature 2000K pure infrared, outer area (1500-3000 meters): execute the original high-sensitivity mode parameters, traffic coordination: the brightness of intersection traffic lights is increased to 150cd / m² (originally 130cd / m²), and the proportion of green light is increased by 20%.

[0041] If it is assessed that the light cluster in the target area at a certain monitoring time point needs to enter the emergency protection mode during the current time period, an emergency protection mode warning will be issued.

[0042] In a specific embodiment, the early warning of the emergency protection mode is as follows: the local sound and light alarm is started and the alarm information containing timestamp, over-limit index and current parameters is pushed to the operation and maintenance terminal. At the same time, the redundant communication link is activated, and emergency notifications are sent to management personnel via SMS or email. At the same time, the environmental monitoring system is linked to synchronize meteorological data and the traffic management system to reduce the surrounding illumination by 10%-20%, and the coordinates of abnormal migratory bird activities are sent to the wildlife protection platform through the API interface. The system automatically retrieves the historical parameter library and the digital twin model to generate candidate solutions. All early warning events synchronously generate encrypted files containing environmental data, parameter snapshots and response records.
