[0037] The existing control technology of phosphor-free multi-primary color street lamps is still limited to meeting a single lighting demand. It is difficult to cope with the dynamic lighting needs of different groups of people in a complex environment, resulting in limited use scenarios of phosphor-free multi-primary color street lamps and poor user experience.

[0038] Based on this, the present application provides a light intensity control system and method for a fluorescent-free multi-primary color street lamp. According to the dynamic light atmosphere adjustment information, the street lamp is controlled to make corresponding light adjustments, and a corresponding atmosphere adjustment report is generated and output, so that the light adjustment strategy of the street lamp can cope with the dynamic needs of different groups of people for light in a complex environment, improve the atmosphere creation effect of the street lamp, and ensure a good user experience.

In the process of controlling non-fluorescent multi-primary color street lamps, the method provided by this application is applied so that the light adjustment strategy of the non-fluorescent multi-primary color street lamps can cope with the dynamic needs of different groups of people for lights in complex environments and improve the atmosphere creation effect of the street lamps.

[0040] Specifically, the method of the present application is applied to any server, which communicates with an environmental monitoring device and a phosphor-free multi-primary color street lamp respectively, obtains ambient lighting information and personnel distribution information provided by the environmental monitoring device through the server, analyzes the ambient lighting information and personnel distribution information, and determines the basic lighting adjustment information required for the street lamp to achieve basic lighting. On this basis, combined with the environmental coordination information and personnel activity information provided by the environmental monitoring device, the real-time atmosphere information required for the street lamp to achieve atmosphere creation is analyzed, and the dynamic elements of personnel in the environment are further considered. Based on the personnel activity information and the real-time atmosphere information, the dynamic lighting atmosphere adjustment information required to maintain a good atmosphere in the dynamic scene of the street lamp is determined, and the street lamp is controlled to make corresponding lighting adjustments accordingly, and a corresponding atmosphere adjustment report is generated and output to the system maintenance personnel, so that the lighting adjustment strategy of the street lamp can cope with the dynamic needs of different groups of people for lighting in a complex environment, improve the atmosphere creation effect of the street lamp, and ensure a good user experience.

[0041] For specific implementation methods, please refer to the following embodiments.

[0042] Figure 2 This is a flow chart of a method for controlling the light intensity of a fluorescent-free multi-primary color street lamp provided in an embodiment of the present application. The method of this embodiment can be applied to the server in the above scenario. Figure 2 As shown, the method includes: S201. Obtain ambient lighting information and personnel distribution information, analyze the ambient lighting information and personnel distribution information, and determine basic lighting adjustment information.

[0043] The ambient light information may be the natural light intensity information of the current environment in which the street lamp is located, and the ambient light information may be obtained through a photoelectric sensor in an environment monitoring device built into the street lamp.

[0044] The personnel distribution information may be personnel distribution status information within the lighting area that the street lamp is responsible for, and the personnel distribution information may be obtained through an infrared sensor in an environment monitoring device built into the street lamp.

[0045] The basic lighting adjustment information may be the light intensity parameter information that needs to be adjusted for the street lamp to achieve good lighting in the lighting area it is responsible for.

[0046] Specifically, compared with ordinary street lamps, non-fluorescent and non-phosphor multi-primary color street lamps have obvious advantages in color performance, energy efficiency and environmental impact. As a result, the application scenarios faced by non-fluorescent and non-phosphor multi-primary color street lamps are more complicated than those of ordinary street lamps. Non-fluorescent and non-phosphor multi-primary color street lamps are suitable for landscape lighting, cultural places and some special occasions, and can achieve the purpose of creating atmosphere that ordinary street lamps cannot do; and when non-fluorescent and non-phosphor multi-primary color street lamps are used in the above-mentioned scenarios, their lighting effects will be affected by both the environment and personnel. In order to ensure that non-fluorescent and non-phosphor multi-primary color street lamps can bring good lighting effects to users while creating an atmosphere, mathematical analysis is used to comprehensively analyze the ambient lighting information and personnel distribution information to obtain the basic lighting adjustment information required for the street lamp to achieve good lighting effects in the current area, providing basic data support for subsequent atmosphere analysis.

[0047] S202: Acquire environmental coordination information and personnel activity information, analyze the environmental coordination information and personnel activity information based on basic lighting adjustment information, and determine real-time atmosphere information.

[0048] Environmental coordination information may be environmental information that has a direct impact on the goal of creating a street lamp atmosphere, and may include weather information, environmental obstruction information, etc. Environmental coordination information may be obtained through a laser scanner in an environmental monitoring device built into a street lamp.

[0049] Personnel activity information can be personnel behavior information that has a direct impact on the goal of creating a street lamp atmosphere. Personnel activity information can be obtained through an image acquisition device in an environmental monitoring device built into the street lamp.

[0050] The real-time atmosphere information may be target parameter information that needs to be adjusted for the street lamp to construct the current target atmosphere.

[0051] Specifically, in the process of using non-fluorescent multi-primary color street lamps to create an atmosphere, the atmosphere creation effect is also affected by the environment and personnel, specifically: the design and layout of the natural landscape and man-made buildings in the surrounding environment will affect the light projection and visual effects of the street lamps. If the light color of the street lamps is coordinated with the color of the surrounding environment, such as consistent with the tones of natural green plants or ancient buildings, it can enhance the overall visual and atmosphere sense, otherwise it may appear abrupt and affect the atmosphere creation; the activity patterns of tourists in the surrounding environment, such as gathering, taking pictures or leisure, will be affected by the light and environment. Appropriate light and shadow effects can promote a better travel experience and create a pleasant atmosphere for tourists. Therefore, the atmosphere creation of street lamps must take into account the needs of personnel interaction for the light environment, and through mathematical analysis, conduct a comprehensive analysis of environmental coordination information and personnel activity information, combined with basic lighting adjustment information, to obtain the factual atmosphere information required for street lamps to create a good atmosphere.

[0052] S203: Determine dynamic lighting atmosphere adjustment information based on personnel activity information and real-time atmosphere information.

[0053] The dynamic lighting atmosphere adjustment information may be the dynamic lighting adjustment information of the street lamp within a period of time obtained by analyzing the real-time atmosphere information in combination with the dynamic elements in the environment surrounding the street lamp.

[0054] Specifically, since the non-fluorescent multi-primary color street lamps need to face the dynamic factor of human activities in the process of atmosphere creation, the lighting strategy of the street lamps should be dynamically adjusted according to the changes in human activities to improve the user experience. Through mathematical analysis, the dynamic impact of human activities on the lighting atmosphere can be quantified to obtain the dynamic lighting atmosphere adjustment information required for street lamps under different human activities.

[0055] S204: According to the dynamic lighting atmosphere adjustment information, the phosphor-free multi-primary color street lamp is controlled to perform corresponding lighting adjustments, and an atmosphere adjustment report is generated and outputted.

[0056] The atmosphere adjustment report may be report information including data on changes in various parameters during the street lamp atmosphere adjustment process.

[0057] Specifically, after obtaining the dynamic lighting atmosphere adjustment information, the lighting control signal corresponding to each parameter in the dynamic lighting atmosphere adjustment information is transmitted to the lighting control unit inside the corresponding street lamp through wireless communication technologies, such as LoRa, Zigbee, etc., to realize remote lighting adjustment of the street lamp. After the adjustment is completed, the various lighting change parameters are integrated through data visualization technology to generate an atmosphere adjustment report, and the atmosphere adjustment report is provided to the system maintenance personnel through human-computer interaction equipment. The atmosphere adjustment report can enable the system maintenance personnel to intuitively understand the dynamic situation of the street lamp, and can also serve as the basis for subsequent street lamp adjustments.

[0058] Through this solution, the ambient lighting information and personnel distribution information are analyzed to determine the basic lighting adjustment information required for the street lamp to achieve basic lighting. On this basis, the environmental coordination information and personnel activity information are combined to analyze the real-time atmosphere information required for the street lamp to achieve atmosphere creation. The dynamic factors of people in the environment are further considered. Based on the personnel activity information and the real-time atmosphere information, the dynamic lighting atmosphere adjustment information required to maintain a good atmosphere in the dynamic scene of the street lamp is determined. The street lamp is controlled to make corresponding lighting adjustments accordingly, and the corresponding atmosphere adjustment report is generated and output, so that the lighting adjustment strategy of the street lamp can cope with the dynamic needs of different groups of people for lighting in a complex environment, improve the atmosphere creation effect of the street lamp, and ensure a good user experience.

[0059] In some embodiments, the overall lighting area is divided according to preset lighting fixture information to determine a number of lighting areas, and the number of areas is determined accordingly; according to preset planning information, the usage types of the several lighting areas are analyzed to determine the ideal lighting intensity of each lighting area; according to the ambient lighting information and personnel distribution information, the ambient light intensity and personnel density of each lighting area are determined; based on the ideal lighting intensity, the lighting intensity requirement value of each lighting area is determined according to the ambient light intensity, personnel density and number of areas; the lighting intensity requirement values ​​of all lighting areas are used as basic lighting adjustment information.

[0060] The preset lamp information may be various factory parameters of the street lamp, and the preset lamp information may be obtained through the description file of the street lamp.

[0061] The overall lighting area can be a lighting area jointly provided by several street lamps.

[0062] The lighting area can be an independent lighting area corresponding to a single street lamp.

[0063] The number of zones may be the total number of lighting zones.

[0064] The preset planning information may be usage planning information for different areas within the overall lighting area, such as a moving line area, a free activity area, an exhibition area, etc. within a scenic area.

[0065] The usage type may be a specific usage type of each lighting area.

[0066] The ideal lighting intensity may be the lighting intensity required to achieve a good lighting effect for the illuminated area under its purpose.

[0067] The ambient light intensity may be the illumination intensity of the ambient light within the corresponding lighting range of the street lamp.

[0068] The occupant density can be the number of occupants per unit area in the lighting area.

[0069] The lighting intensity requirement value may be a specific value of the lighting intensity that a street lamp needs to achieve a good lighting effect under the current conditions within its lighting area.

[0070] Specifically, in an overall lighting area, there are differences in the nature of use, functions and needs between different areas, which leads to differences in the lighting intensity requirements in different areas. In order to enable different street lamps to make targeted optimizations according to the differentiated needs in the lighting areas they are responsible for, so as to achieve the purpose of improving lighting effects and optimizing energy allocation, the lighting radiation range of each street lamp is extracted by pre-setting lamp information, so as to divide the overall lighting area, obtain the lighting areas corresponding to the lighting range of each street lamp, and determine the number of areas. The preset planning information is further analyzed to determine the use types of different lighting areas, and the ideal lighting intensity corresponding to the illuminated areas of different use types is determined based on historical lighting data. At the same time, the ambient light intensity and personnel density in different lighting areas are extracted from the ambient light information and personnel distribution information. On this basis, through mathematical analysis, based on the ideal lighting intensity, according to the ambient light intensity, personnel density and the number of areas, the lighting intensity requirement value required for each lighting area to achieve a good lighting effect is quantitatively analyzed, and the lighting intensity requirement values ​​corresponding to different lighting areas are used as basic lighting intensity information to provide a basic data framework for subsequent atmosphere analysis.

[0071] Through this solution, the overall lighting area is divided, and several lighting areas and the number of areas are determined. At the same time, according to the preset planning information, the ideal lighting intensity corresponding to the illumination area of ​​each use type is determined, and the ambient light intensity and personnel density are extracted from the ambient lighting information and personnel distribution information respectively. The ideal lighting intensity, ambient light intensity, personnel density and number of areas are comprehensively analyzed to obtain the lighting intensity demand value required for each lighting area to achieve a good lighting effect. The lighting intensity demand values ​​corresponding to different lighting areas are used as basic lighting intensity information, so that different street lamps can be optimized according to the differentiated needs in the lighting area they are responsible for, so as to achieve the purpose of improving lighting effects and optimizing energy allocation.

[0072] In some embodiments, based on the ideal lighting intensity, the lighting intensity requirement value of each lighting area is determined according to the ambient light intensity, the density of people, and the number of areas, specifically, the following formula (1): (1) in, For the The lighting intensity requirement value of each lighting area, is the number of regions, For the The density of people in each lighting area, is the preset gain factor, For the The ideal lighting intensity for each lighting area, For the The ambient light intensity of a lighting area.

[0073] The preset gain coefficient may be a numerical value reflecting the degree of gain of the lighting intensity demand value due to the increase in personnel density, and the preset gain coefficient may be obtained through experimental data.

[0074] Specifically, through formula (1) Describes the lighting intensity that needs to be gained relative to the ambient light intensity to achieve the ideal lighting intensity, and then Describes the relationship between population density and lighting demand, that is, the higher the population density, the higher the required lighting intensity. At the same time, the above lighting intensity is adjusted by introducing a preset gain coefficient to avoid large errors caused by a single-dimensional coefficient relationship, so as to obtain a more accurate lighting intensity demand value.

[0075] Through this solution, mathematical analysis is used to comprehensively consider the ideal lighting intensity, ambient light intensity, personnel density and number of areas, and a mathematical formula is designed to accurately calculate the lighting intensity demand values ​​corresponding to different lighting areas, so as to scientifically quantify the lighting needs of different lighting areas, further optimize the differentiated lighting needs, and improve the lighting effect.

[0094] Specifically, the process of rendering and creating the atmosphere using non-fluorescent multi-primary color street lamps is mainly affected by two major directions: the environment and personnel. The influence from personnel mainly depends on their behavior. The behavior of personnel in the scenic area tends to be orderly activities or free activities. When conducting orderly activities, tourists usually follow specific routes and time arrangements. The color of the lights can be designed to be more unified and standardized to enhance the atmosphere of the activities. In the free activity mode, tourists move more casually, and the lights can be more creative and diverse, using different colors and changes to attract tourists' attention, such as using colorful lights to increase the fun and exploratory nature of the scenic area.

[0095] The influence from the environment mainly comes from three directions: weather, obstructions and regional themes. Weather has a direct impact on regional visibility, and changes in visibility have different requirements for color temperature. For example, on cloudy or rainy days, people tend to use lights with higher color temperatures to compensate for visibility and create a sense of brightness. The obstruction index, reflection scale and average reflectivity of different types of obstructions directly affect the color temperature performance of street lighting, and the ambient color index reflecting the color tone of the obstructions directly affects the coordination between street lighting and the environment. The theme of the lighting area also affects the color temperature requirements in the process of creating an atmosphere. For example, cultural and historical themes usually use warm tones or neutral color temperatures (3000K-3500K) to create a sense of cultural thickness, while natural scenery scenic spots usually use natural color temperatures (2700K-3000K) to highlight the natural charm.

[0096] In summary, through mathematical analysis, the parameters quantified by different means are further combined and analyzed to obtain the target color temperature, target color index and target brightness required for street lamps to create a good atmosphere, so as to construct a target atmosphere model described by mathematical language, and use the target atmosphere model as real-time atmosphere information to describe the target atmosphere through quantitative data with clear directionality.

[0097] Through this scheme, starting from the two directions of environmental impact and personnel impact, a series of indicators that affect the demand for street lamp atmosphere creation are analyzed, and the target color temperature, target color index and target brightness required for street lamps to create a good atmosphere are obtained, so as to construct a target atmosphere model described by mathematical language, and use the target atmosphere model as real-time atmosphere information to describe the target atmosphere through quantitative data with clear directionality.

[0105] The preset color temperature adjustment coefficient may be a value reflecting the degree of influence of the target color temperature on the target brightness, and the preset color temperature adjustment coefficient may be obtained by fitting lighting experiment data.

[0106] The preset color adjustment coefficient may be a value reflecting the degree of influence of the target color index on the target brightness, and the preset color adjustment coefficient may be obtained by fitting lighting experiment data.

[0107] Specifically, through formula (2) Describe the influence of the theme culture index on the target color temperature, and use the square term to represent the incremental influence of the theme culture index on the target color temperature; Describe the nonlinear relationship between the target color temperature and the target color index in perception, through Describes the effect of ambient color on the target color index, using the sine function to capture the perceived effect of hue changes. , using the exponential decay function to express the nonlinear effect of the behavior type index on the target color index, after obtaining the target color temperature and target color, The lighting intensity requirement value is linearly adjusted to obtain the target brightness.

[0108] Through this scheme, mathematical analysis methods are used to analyze a series of indicators that affect the needs of creating street lamp atmosphere. By clarifying the mathematical formula, the target color temperature, target color index and target brightness required for street lamps to create a good atmosphere are accurately quantified, and the corresponding target atmosphere model is constructed based on this, which improves the scientificity and accuracy of the target atmosphere analysis process.

[0109] In some embodiments, the environmental factor is determined according to the occlusion index, the reflection scale and the average reflectivity, specifically as follows: (3) in, For environmental factors, is the occlusion index, is the reflection scale, is the average reflectivity, To preset adjustment parameters, It is the preset reflection influence coefficient.

[0110] The preset adjustment parameter may be a value used to adjust the degree of influence of the shading index on the environmental factor, and the preset adjustment parameter may be obtained by fitting the lighting experiment data.

[0111] The preset reflection influence coefficient may be a value reflecting the degree of influence of the reflection scale on the environmental factors, and the preset reflection influence coefficient may be obtained by fitting the lighting experiment data.

[0112] Specifically, through formula (3) Under the influence of occlusion and average reflectivity, the occlusion index causes a nonlinear attenuation effect on the environmental factors, and Describe the impact of reflection scale on environmental factors, and use the square term to describe that the impact of reflection scale on environmental factors will increase significantly with the increase of reflection volume or area.

[0113] Through this solution, mathematical analysis methods are used to scientifically quantify environmental factors through clear mathematical formulas based on the occlusion index, reflection scale and average reflectivity to improve the accuracy of environmental factors. The target color temperature calculated on this basis is highly consistent with the environmental state of the street lamp, further improving the accuracy and comprehensiveness of the target atmosphere model.

[0118] Specifically, in the process of street lamps creating atmosphere, the dynamic changes of people within their lighting range will affect the light intensity requirements during the atmosphere creation process, and then affect the atmosphere creation effect of the street lamps under different personnel states. By extracting the personnel density values ​​corresponding to different time points under the personnel density change information, the dynamic personnel density at different time points within the lighting range of the street lamps is determined. On this basis, mathematical analysis is used to obtain the dynamic light intensity required for the lighting range at different time points, and the real-time atmosphere information and the dynamic light intensity at different time points are used as dynamic lighting atmosphere adjustment information, so that the atmosphere creation strategy of the street lamp can change according to the dynamic situation of people within the lighting range, thereby further improving the atmosphere creation effect.

[0119] Through this scheme, according to the changes in population density within the lighting range of street lamps, the concept of dynamic light intensity is introduced into the target atmosphere model, and the dynamic light intensity corresponding to different time points is determined by the dynamic population density at different time points within the lighting range, so that the atmosphere creation strategy of street lamps can change according to the dynamic situation of people within the lighting range, further improving the atmosphere creation effect.

[0120] In some embodiments, based on the target brightness and the dynamic personnel density at different time points, the dynamic light intensity corresponding to different time points is determined, specifically, as follows: (4) in, For the current time point Dynamic light intensity under is the target brightness, Current time point Dynamic population density under For the previous time point Dynamic population density under To adjust the frequency for the preset, is the preset phase offset.

[0122] The preset phase offset may be a parameter reflecting the temporal relationship between light intensity requirements and changes in personnel density, and the preset phase offset may be obtained by fitting historical data.

[0123] Specifically, through formula (4) Reflects the change in the density of people within the lighting range per unit time. The change may be an increase or a decrease.
