Technical Field
[0001] The present invention relates to the technical field of building intelligent control, and particularly to a method for coordinated and adaptive adjustment of lighting and shading in smart buildings. Background Art
[0002] With the popularization of the concepts of smart buildings and green buildings, the intelligent control of lighting and shading systems has become an important means to improve building energy efficiency and user comfort. Traditional lighting and shading systems often operate independently and lack coordination, resulting in energy waste and insufficient comfort. For example, on a sunny day, if the shading system is not adjusted in time, it may cause indoor glare. At this time, it is difficult to completely compensate for the light environment quality only by dimming the lighting system; conversely, if the shading is excessive, additional lighting needs to be turned on, increasing energy consumption.
[0003] In the prior art, although some systems have tried coordinated control, most of them adopt control strategies with simple rules and fixed thresholds, and it is difficult to adapt to changing environments and user needs. The lack of a dynamic weight mechanism and feedback optimization ability results in system response lag, low adjustment accuracy, and limited energy efficiency optimization. Therefore, there is an urgent need for a coordinated adjustment method and system that can real-time sense environmental changes, intelligently weigh the priorities of shading and lighting, and have the ability of self-learning and optimization. Summary of the Invention
[0004] A method and system for coordinated and adaptive adjustment of lighting and shading in smart buildings, comprising:
[0005] S1. The smart building system collects indoor and outdoor light data through light sensors and calculates the light deviation value from the preset comfort range;
[0006] S2. Analyze the intensity, duration, and change trend of outdoor light, evaluate the availability of natural light and its potential contribution to indoor lighting, and then comprehensively consider the numerical values and distribution characteristics of the light deviation in each indoor area to calculate the spectral weight factor for weighing the priorities of shading and lighting adjustment;
[0007] S3. According to the adjustment tendency indicated by the spectral weight factor, parallelly calculate the shading angle compensation value and the lighting brightness compensation value, and perform validity verification and range constraint on the preliminary calculation results;
[0008] S4. According to the shading angle compensation value and the lighting brightness compensation value, trigger the feedback mechanism to synchronously drive the shading device and the lighting fixture to perform adjustment and update their current states; [[ID=�0]]
[0009] S5. According to the pre-constructed multi-dimensional comprehensive evaluation system of energy efficiency and comfort, monitor the energy consumption and comfort data after adjustment, calculate the comprehensive energy efficiency index, and accordingly feedback and optimize the calculation rule of the spectral weight factor to complete the adaptive adjustment closed-loop.
[0010] The above-described adaptive adjustment method for lighting and shading linkage in smart buildings includes the following sub-steps: The smart building system collects indoor and outdoor lighting data through light sensors and calculates the lighting deviation value from a preset comfort range.
[0011] Simultaneously, data on light intensity in different functional areas indoors and from multiple directions outside the building were collected;
[0012] The collected real-time illumination data is compared with the preset comfortable illumination range for each area in the system, and the specific deviation between the current illumination level and the median or optimal value of the comfortable range for each area is calculated.
[0013] The deviation of all regions is analyzed, regions with deviations exceeding the preset allowable threshold are selected, and these regions are accurately marked as the regions that need to be adjusted first.
[0014] The above-described adaptive adjustment method for lighting and shading linkage in smart buildings includes the following sub-steps: Calculating a spectral weighting factor that balances the priorities of shading and lighting adjustment based on illumination deviation values and outdoor illumination data.
[0015] Based on the intensity, duration, and trend of outdoor light, a comprehensive assessment is made of the current availability of natural light and its potential contribution to indoor lighting.
[0016] Based on the specific values and spatial distribution of light deviation in various indoor areas, the weight allocation ratio between shading adjustment and electrical lighting adjustment at the current moment is calculated.
[0017] Based on the above analysis, a dynamically adjustable spectral weighting factor is generated, which can be directly used in the subsequent parallel calculation of shading and lighting compensation values.
[0018] The above-described adaptive adjustment method for lighting and shading linkage in smart buildings, which utilizes a spectral weighting factor to calculate shading angle compensation values and lighting brightness compensation values in parallel, includes the following sub-steps:
[0019] Based on the regulation tendency indicated by the spectral weighting factor, the proportion of the total regulation amount that can be used for shading regulation and lighting regulation should be reasonably allocated;
[0020] Calculate independently the angle offset required for the shading blades to achieve the target shading effect, and the brightness compensation value required for the lighting fixtures to supplement indoor lighting.
[0021] The angle compensation value and brightness compensation value obtained from the preliminary calculation are validated and their range is constrained to prevent overshoot, equipment overload or energy waste.
[0022] The above-described adaptive adjustment method for the linkage between lighting and shading in smart buildings includes the following sub-steps: The method independently calculates the angle offset required for the shading blades to achieve the target shading effect, and the brightness compensation value required for the lighting fixtures to supplement indoor illumination.
[0023] Based on the current blade angle of the shading device, the outdoor sun's azimuth and altitude angle, calculate the blade angle value that needs to be adjusted to block excess glare or introduce an appropriate amount of natural light.
[0024] Based on the illumination deviation in each indoor area and the expected contribution of natural light after passing through the shading system, the brightness values that the electrical lighting system needs to supplement or reduce are calculated.
[0025] Conduct a synergistic check on the adjustment amount of the shading angle and the adjustment amount of the lighting brightness to ensure that the adjustment directions of the two are consistent and do not conflict, and avoid over-adjustment or mutual cancellation.
[0026] The above-described adaptive adjustment method for lighting and shading linkage in smart buildings includes the following sub-steps: Based on shading angle compensation values and lighting brightness compensation values, the shading device and lighting fixtures are synchronously driven to perform adjustments and their current states are updated.
[0027] After the adjustment action is completed, the light data of each area in the room is immediately collected again by the light sensor to verify whether the adjustment effect has brought the light level into the preset comfortable range.
[0028] Accurately record the energy consumption data of the sunshade motor and lighting fixtures during this adjustment process, and calculate the energy efficiency ratio of this adjustment action;
[0029] If the verification finds that the adjustment effect does not meet the expected target, or the energy efficiency ratio is too low, the feedback mechanism will be automatically triggered to recalculate the spectral weighting factor and start a new round of adjustment.
[0030] The adaptive adjustment method for integrated lighting and shading in smart buildings, as described above, involves monitoring energy consumption and comfort data after adjustment, calculating a comprehensive energy efficiency index, and using this as feedback to optimize the calculation rules for the spectral weighting factor, thus completing the adaptive adjustment closed loop. This includes the following sub-steps:
[0031] Based on the multiple adjustment records accumulated during the system's historical operation and their corresponding energy consumption results and comfort compliance status, a multi-dimensional comprehensive evaluation system for energy efficiency and comfort is established.
[0032] Based on the latest comprehensive evaluation results, the key parameters and calculation logic involved in the calculation of the spectral weighting factor are adjusted in reverse.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.
[0052] Example 1
[0053] like Figure 1 As shown in the figure, an embodiment of this application provides a method for adaptive adjustment of lighting and shading linkage in smart buildings, comprising:
[0054] Step S1: The smart building system collects indoor and outdoor lighting data through light sensors and calculates the lighting deviation value from the preset comfort range;
[0055] Specifically, by synchronously collecting illumination data from various functional areas indoors and from multiple directions outside the building, and comparing the real-time data with the system's preset comfortable illumination ranges for each area, the deviation from the median or optimal value of the comfortable range is calculated. Then, the deviation of all areas is analyzed, and areas exceeding the set threshold are accurately marked as target areas requiring priority adjustment. This includes the following sub-steps:
[0056] Step S11: Simultaneously collect light intensity data from different functional areas indoors and from multiple directions outside the building;
[0057] The system uses high-precision light sensors deployed in various functional areas, as well as external sensors installed on multiple orientations of the building facade, to synchronously acquire light intensity data at a fixed sampling frequency. All sensor data is transmitted to the central processing unit in real time via wired or wireless communication protocols to ensure that the data is strictly aligned in timestamps and to avoid inconsistencies in spatial lighting conditions caused by acquisition delays.
[0058] Step S12: Compare the collected real-time illumination data with the preset comfortable illumination range for each area in the system, and calculate the specific deviation between the current illumination level of each area and the median or optimal value of the comfortable range.
[0059] Based on the purpose of each functional area and the human body's comfortable lighting requirements, a standard illuminance range is pre-set; the real-time collected illuminance values are compared with the median or optimal reference value of the corresponding area's comfort range, and the absolute and relative deviations are calculated using formulas:
[0060] Absolute deviation: in, Indicates the first Each region at the reference time The absolute deviation at that point; It indicates that it is the first Each region at the reference time The absolute value of a certain original deviation at a certain location; This represents the normalized attenuation coefficient; Indicates the first Historical variance of illumination in each region; Indicates the first The optimal light intensity value for each region.
[0061] Relative deviation: in, Indicates the first Each region at the reference time The relative deviation at the location; Indicates the first Each region at the reference time The absolute deviation at that point; Indicates the first The optimal light intensity value for each region; Indicates the first The upper limit of the comfort range for each area; Indicates the first The lower limit of the comfort range for each region; Indicates the range width index.
[0062] The positive and negative directions and magnitudes of the deviations in each area are recorded to form a list of regional illumination state deviations.
[0063] Step S13: Analyze the deviation of all regions, screen out the regions whose deviation exceeds the preset allowable threshold, and accurately mark them as the regions to be adjusted that need to be adjusted first.
[0064] Set a dynamically adjustable deviation tolerance threshold, sort and prioritize the deviation amounts of all regions; identify regions whose absolute deviation values exceed the threshold as abnormal regions, and determine the urgency of adjustment based on the magnitude and duration of the deviation; finally, generate a list of regions to be adjusted and push it to the linkage control module as the basis for adjustment decisions.
[0065] Step S2: Calculate the spectral weighting factor that balances the priorities of shading and lighting adjustment based on the light deviation value and outdoor light data;
[0066] Specifically, by analyzing the intensity, duration, and trend of outdoor light, the availability of natural light and its potential contribution to indoor lighting are assessed. Then, considering the numerical and distribution characteristics of light deviations in different indoor areas, the weighting ratio of shading adjustment and electrical lighting adjustment at the current moment is calculated. This generates a dynamically adjustable spectral weighting factor for subsequent parallel calculations of shading and lighting compensation values, including the following sub-steps:
[0067] Step S21: Based on the intensity, duration and trend of outdoor light, comprehensively judge the current availability of natural light and its potential contribution to indoor lighting.
[0068] By monitoring the intensity, duration, and trends of outdoor light in real time, the availability of natural light in both time and space is comprehensively assessed to determine its potential contribution to indoor lighting systems.
[0069] Step S22: Based on the specific values and spatial distribution of the light deviation in each area of the room, calculate the weight distribution ratio between the shading adjustment behavior and the electrical lighting adjustment at the current moment.
[0070] Based on the real-time collected illumination deviation values of various indoor areas and their spatial distribution characteristics, we identify areas with insufficient or excessive illumination. Combining the functional attributes of these areas with human comfort requirements, we calculate the respective weighting ratios of shading and electrical lighting adjustments under the current environmental conditions. The following formula represents the respective weighting ratios of shading and electrical lighting adjustments:
[0071] in, Indicates time The weighting percentage of "prioritizing shading control"; Indicates the first A point in time; Indicates the adjustment parameter, used for control. right Sensitivity; Represents variables related to solar radiation; Variables related to the thermal environment; Variables representing the potential for natural lighting; This indicates the lighting adjustment weight.
[0072] Step S23: Based on the above analysis, generate a dynamically adjustable spectral weighting factor, which can be directly used in the subsequent parallel calculation of shading and lighting compensation values;
[0073] Based on the aforementioned analysis results, a spectral weighting factor that can dynamically respond to environmental changes is generated. This factor serves as a comprehensive control coefficient and is used to rationally allocate the proportions of the shading device and the electrical lighting system in the overall adjustment strategy when calculating the compensation values of the shading device and the electrical lighting system in parallel, thereby achieving the optimal balance between energy consumption and comfort between the shading and lighting systems.
[0074] Step S3: Using the spectral weighting factor, calculate the shading angle compensation value and the lighting brightness compensation value in parallel.
[0075] Specifically, based on the spectral weighting factor and The indicated adjustment tendency is used to reasonably allocate the proportion of the total adjustment available for the shading and lighting systems; the angle offset required for the shading blades to achieve the target shading effect and the brightness compensation value required for the lighting fixtures to supplement indoor lighting are calculated independently—the shading angle is calculated based on the current blade status, solar azimuth, and altitude angle to block glare or introduce an appropriate amount of natural light, while the lighting brightness is calculated to compensate for the light deviation and natural light contribution in each area; the adjustment amounts of both are checked for synergy to ensure consistent adjustment directions and avoid conflicts or cancellations; finally, the preliminary calculation results are validated and range-bound to prevent overshoot, equipment overload, or energy waste, including the following sub-steps:
[0076] Step S31: Based on the adjustment tendency indicated by the spectral weighting factor, reasonably allocate the proportion of the total adjustment amount that can be used for shading adjustment and lighting adjustment;
[0077] Based on the weighting factors extracted from the real-time spectral analysis results, the system determines whether the current environment is dominated by shading adjustment or lighting compensation, and then dynamically allocates the proportion of adjustment resources that can be used for shading mechanisms and lighting equipment.
[0078] Step S32: Calculate independently the angle offset required for the shading blades to achieve the target shading effect, and the brightness compensation value required for the lighting fixtures to supplement indoor lighting.
[0079] Step S321: Based on the current blade angle of the shading device, the outdoor sun's azimuth and altitude angle information, calculate the blade angle value that needs to be adjusted to block excess glare or introduce an appropriate amount of natural light.
[0080] The system accesses solar position parameters provided by a real-time astronomical calculation module, and combines these with structural parameters such as building facade orientation and window-to-wall ratio to calculate the ideal shading angle hourly using formulas.
[0081] in, Indicates the ideal shading angle; Represents the arcsine function; Indicates the altitude angle of the sun; Indicates the azimuth of the sun; Indicates the orientation of the building facade; Indicates the building construction correction factor; Indicates the building construction correction factor; Indicates the efficiency coefficient; This indicates the final shading angle compensation value; Indicates the current blade angle; This indicates the weight of the shading adjustment.
[0082] Use shading adjustment weight The angles are weighted to reflect the priority of shading adjustments.
[0083] Step S322: Based on the illumination deviation of each indoor area and the expected contribution of natural light after passing through the shading system, calculate the brightness value that the electrical lighting system needs to supplement or reduce.
[0084] The system acquires the actual light distribution through a network of illuminance sensors deployed in the space, compares it with the set target value to determine the deviation, and then, combined with a natural light penetration model after shading adjustment, estimates the light gap that still needs to be supplemented by artificial lighting. Finally, it uses a formula to calculate the target brightness value of the lighting equipment.
[0085] in, Indicates the target brightness value of the lighting equipment; Indicates the efficiency coefficient of the lighting system; Indicates the natural light utilization coefficient; This indicates the target illuminance that the scene needs to achieve; Indicates solar radiation intensity; This represents the cloud cover correction factor; This indicates the change in the sun's angle; This represents the correction factor for the average illuminance deviation; Indicates the deviation of average illuminance; Represents the system correction constant; This indicates the final lighting brightness compensation value; Indicates the current brightness value; This indicates the lighting adjustment weight.
[0086] Step S323: Perform a coordination check on the shading angle adjustment amount and the lighting brightness adjustment amount to ensure that the two adjustment directions are consistent and do not conflict, and avoid over-adjustment or mutual cancellation.
[0087] Step S33: Verify the validity and constrain the range of the angle compensation value and brightness compensation value obtained from the preliminary calculation to prevent phenomena such as adjustment overshoot, equipment overload or energy waste.
[0088] The system is equipped with physical limit checks and energy boundary judgment mechanisms to limit the amplitude and rate of change of all output commands, avoiding mechanical impacts or frequent large-scale dimming of lighting equipment; at the same time, it incorporates historical regulation efficiency evaluation data to filter and correct abnormal or inefficient commands, ensuring that the output regulation is within the allowable range of the equipment and meets the requirements of green operation.
[0089] Step S4: Based on the shading angle compensation value and the lighting brightness compensation value, synchronously drive the shading device and lighting fixtures to perform adjustments and update their current status;
[0090] Specifically, immediately after adjustment, real-time light data for each area is collected via light sensors to assess whether the actual light level meets the expected comfort range; simultaneously, energy consumption data of the shading motor and lighting fixtures are accurately recorded, and the energy efficiency ratio of this adjustment is calculated; if the adjustment effect is not achieved or the energy efficiency ratio is too low, a feedback mechanism is automatically triggered to recalculate the spectral weighting factor and initiate a new round of adjustment to achieve more precise light environment control and energy consumption optimization, including the following sub-steps:
[0091] Step S41: After the adjustment action is completed, immediately re-collect the light data of each area in the room through the light sensor to verify whether the adjustment effect has brought the light level into the preset comfortable range.
[0092] The measured illuminance values of each area are compared with the preset comfortable illuminance range to determine whether all areas are within the target illuminance range. The degree of deviation and distribution of non-compliant areas are also statistically analyzed as a basis for evaluating the adjustment effect.
[0093] Step S42: Accurately record the energy consumption data of the sunshade motor and lighting fixtures during this adjustment process, and calculate the energy efficiency ratio of this adjustment action;
[0094] Based on the ratio of the improvement in light intensity to the total energy consumption, the energy efficiency ratio for this adjustment is calculated using the following formula:
[0095] in, Indicates the normalized energy efficiency ratio; This represents quantities related to light-related benefits; Indicates total energy consumption; Indicates the base energy offset; Indicates time-related quantities; This represents the time penalty coefficient.
[0096] This is used to comprehensively evaluate the economic efficiency and energy conservation of this coordinated regulation.
[0097] Step S43: If the verification finds that the adjustment effect has not reached the expected target, or the energy efficiency ratio is too low, the feedback mechanism will be automatically triggered to recalculate the spectral weighting factor and start a new round of adjustment.
[0098] Based on the actual degree of light deviation and energy efficiency deviation, the spectral weighting factor is recalculated, and the compensation parameters are corrected in conjunction with historical adjustment records. A new round of shading and lighting linkage adjustment is initiated until the actual light distribution and energy efficiency ratio meet the requirements.
[0099] Step S5: Monitor the adjusted energy consumption and comfort data, calculate the comprehensive energy efficiency index, and optimize the calculation rules of the spectral weighting factor based on the feedback to complete the adaptive adjustment closed loop.
[0100] Specifically, based on multiple adjustment records accumulated during the system's historical operation and their corresponding energy consumption and comfort compliance status, a multi-dimensional comprehensive evaluation system for energy efficiency and comfort is constructed. Based on the latest comprehensive evaluation results, key parameters and calculation logic in the spectral weighting factor calculation process are adjusted in reverse. Through continuous iterative optimization and experience learning, the system gradually acquires the ability to adapt to changes in light intensity on different dates, at different times of day, and in different seasons. This includes the following sub-steps:
[0101] Step S51: Based on the multiple adjustment records accumulated in the historical operation of the system and their corresponding energy consumption results and comfort standards, establish a multi-dimensional comprehensive evaluation system for energy efficiency and comfort.
[0102] Historical adjustment records are extracted from the actual operation database of the lighting and shading linkage system, including lighting power, number of shading mechanism actions, indoor illuminance uniformity, user comfort feedback, and total energy consumption data for each time period. These data are cleaned and normalized to construct a comprehensive evaluation system with energy consumption per unit area, comfort compliance rate, and light stability as core indicators. A weighted aggregation method is used to generate a comprehensive energy efficiency index, where the weights of each indicator are configured according to the dynamic needs of the actual application scenario, ensuring that the evaluation results reflect both energy-saving effects and environmental comfort.
[0103] Step S52: Based on the latest comprehensive evaluation results, adjust the key parameters and calculation logic involved in the calculation of the spectral weighting factor in reverse.
[0104] The comprehensive energy efficiency index is compared with the preset target range. If the evaluation result does not meet expectations, the parameter adjustment mechanism is activated. Based on the ratio between energy efficiency deviation and comfort deviation, the adjustment direction and magnitude of key parameters such as illuminance compensation coefficient and spectral sensitivity factor used in the calculation of spectral weighting factor are determined. By establishing a parameter-performance response relationship table, the current optimal parameter correction strategy is inferred, and the updated parameter set is applied in the next calculation cycle to gradually approach the optimal energy efficiency-comfort balance point.
[0105] Step S53: Through continuous iterative optimization and experience learning, the system can gradually adapt to the changing characteristics of light intensity brought about by different dates, different times of day, and different seasons.
[0106] After each adjustment and evaluation, the system automatically records the current environmental characteristics, adjustment parameters, and comprehensive energy efficiency indicators to form an experience dataset. Based on this dataset, the calculation rules for the spectral weighting factor are periodically optimized to identify the optimal parameter combinations under different seasons, weather conditions, and time periods. By introducing time series analysis and rule reasoning mechanisms, the system can gradually build a knowledge base for responding to changes in illumination, thereby achieving long-term adaptive adjustment without human intervention.
