[0054] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.
[0055] Embodiment 1
[0056] like Figure 1 As shown, an energy-saving intelligent lighting control system, the control system comprises:
[0057] An ambient brightness acquisition module is used to acquire current ambient light data of a target lighting area through an ambient light sensor based on the target lighting area, and generate corresponding target ambient lighting brightness according to the current ambient light data;
[0058] Among them, the ambient brightness acquisition module can use a high-precision ambient light sensor to collect real-time data on the lighting area. These data specifically include key parameters such as ambient light intensity and color temperature in the current lighting area, and then determine the target ambient lighting brightness.
[0059] Through the above method, the natural light changes in the lighting area can be simulated, thereby improving the user experience and reducing unnecessary energy consumption.
[0060] A human activity recognition module, used to recognize human activity information in the target lighting area through a human activity sensor, and determine the corresponding target activity lighting brightness according to the human activity information;
[0061] It is understandable that the personnel activity recognition module can perform non-contact monitoring of personnel activities in the lighting area by deploying human activity sensors, such as infrared sensors, radar sensors, etc.
[0062] Specifically, the module can intelligently identify the number of people, movement trajectories and activity intensity, and dynamically adjust the lighting brightness of the target activity accordingly to ensure that the lighting needs are highly matched with the actual activity status of the people, further promoting the efficient use of energy.
[0063] A control strategy generation module, used to determine a target adjusted lighting brightness based on the target environment lighting brightness and the target activity lighting brightness, and generate a corresponding adaptive lighting brightness control strategy in combination with the actual lighting brightness;
[0064] It should be noted that the control strategy generation module can integrate the output information of the environment brightness acquisition module and the personnel activity recognition module to calculate the optimal target adjustment lighting brightness.
[0065] At the same time, the module can obtain the actual lighting brightness of the lighting area in real time, and generate an adaptive lighting brightness control strategy through comparative analysis, thereby achieving dual optimization of lighting comfort and energy-saving effects.
[0066] A real-time adjustment monitoring module, used to adjust the brightness of the target lighting device in the target lighting area based on the adaptive brightness control strategy, and monitor the current lighting energy consumption data of the target lighting device through a lighting energy consumption sensor;
[0067] Among them, the real-time adjustment monitoring module can accurately adjust the brightness of the intelligent lighting equipment in the lighting area according to the adaptive lighting brightness control strategy output by the control strategy generation module.
[0068] In addition, the module is also integrated with lighting energy consumption sensors, which can monitor and record the energy consumption data of each lighting device in real time, which is helpful for subsequent energy efficiency analysis and strategy optimization.
[0069] The strategy optimization and adjustment module is used to obtain lighting feedback information from the user end, and optimize the adaptive lighting brightness control strategy based on the lighting feedback information and the current lighting energy consumption data.
[0070] It is understandable that the strategy optimization and adjustment module can collect user feedback on lighting effects through the user-side interface, and continuously optimize the adaptive lighting brightness control strategy in combination with the lighting energy consumption data monitored in real time.
[0071] Through the above methods, the adaptive ability of the lighting system can be improved, and it can be ensured that the adaptive lighting brightness control strategy can continue to meet the diverse needs of users and achieve maximum benefits in energy use.
[0072] In the specific implementation process, Figure 2 As shown, the ambient brightness acquisition module 200 is used to collect the current ambient light data of the target lighting area through the ambient light sensor based on the target lighting area, and generate the corresponding target ambient lighting brightness according to the current ambient light data, specifically including:
[0073] A deployment unit 201 is used to deploy a plurality of the ambient light sensors according to the distribution of the target lighting devices in the target lighting area;
[0074] A collection unit 202 is used to collect current ambient light data of the target lighting area in real time through the ambient light sensor;
[0075] The determination unit 203 is configured to determine the target ambient lighting brightness of the target lighting area if the current ambient light data meets the preset lighting requirement.
[0076] Among them, the ambient brightness acquisition module can efficiently collect the current ambient light data in the lighting area through the ambient light sensor, so as to quantitatively measure the light intensity in the lighting area and comprehensively evaluate multi-dimensional information such as light quality and color temperature.
[0077] Specifically, the deployment unit can reasonably deploy multiple ambient light sensors based on the spatial distribution characteristics of the lighting equipment in the lighting area, combined with the type, power and positional relationship of the lighting equipment, thereby ensuring that the ambient light sensors can fully cover and accurately reflect the light environment conditions of the entire lighting area.
[0078] The collection unit can collect the current ambient light data of the lighting area in real time and continuously through the deployed ambient light sensors. The unit can use the high sensitivity of the sensor to quickly capture the slight changes in the light intensity in the lighting area and the light fluctuations in different time periods.
[0079] After obtaining the current ambient light data, the determination unit can perform in-depth analysis and comparison of these current ambient light data according to preset lighting requirements, such as light intensity range, energy-saving indicators, comfort considerations, etc.
[0080] Specifically, if the current ambient light data meets the preset lighting requirements, the determination unit will determine the target ambient lighting brightness of the lighting area accordingly, thereby ensuring the intelligent operation of the lighting system and effectively improving lighting efficiency and user experience.
[0081] The determining the corresponding target activity lighting brightness according to the personnel activity information specifically includes:
[0082] The average frequency of personnel activities in the target lighting area is calculated according to the personnel activity information. The calculation formula of the average frequency of personnel activities is as follows:
[0083]
[0084] In the formula, HDPL t represents the moving average value at the current time t, that is, the average frequency of personnel activities in the target lighting area at the current time t; n represents the number of moving average cycles; JR i Indicates the number of people entering the target lighting area at time i; LK i represents the number of people leaving the target lighting area at time i;
[0085] The target activity lighting brightness is determined according to the average frequency of human activities in the target lighting area.
[0086] In practical applications, firstly, the average frequency of personnel activities in the lighting area can be calculated using the moving average method based on the personnel activity information.
[0087] Then, the target activity lighting brightness can be further determined based on the average frequency of human activities in the lighting area, thereby ensuring that the lighting system achieves efficient use of energy while meeting the actual needs of human activities.
[0088] The process of determining the target lighting brightness adjustment is as follows:
[0089] Set the target ambient lighting brightness at the current time t to HJLD t , and the target activity lighting brightness is HDLD t ;
[0090] Obtain the device brightness adaptation factor of the target lighting device in the target environment area, and determine the target adjusted lighting brightness by balancing the target environment lighting brightness, the target activity lighting brightness, and the influence of the device brightness adaptation factor on the target adjusted lighting brightness. The calculation formula of the target adjusted lighting brightness is as follows:
[0091] TJLD t =α HJ *HJLD t +α HD *HDLD t +α SB *τ
[0092] α HJ +α HD +α SB =1
[0093] Where, TJLD t represents the target adjustment lighting brightness at the current time t; α HJ Indicates the weight coefficient corresponding to the target environment lighting brightness, that is, the degree of influence of the target environment lighting brightness on the target adjustment lighting brightness; HJLD t Represents the target environment lighting brightness at the current time t; α HD Indicates the weight coefficient corresponding to the target activity lighting brightness, that is, the degree of influence of the target activity lighting brightness on the target adjustment lighting brightness; HJLD t represents the target activity lighting brightness at the current time t; α SB It represents the weight coefficient corresponding to the device brightness adaptation factor, that is, the influence of the device brightness adaptation factor on the target adjusted lighting brightness; τ represents the device brightness adaptation factor of the target lighting device in the target environment area.
[0094] It should be noted that, first, the target environment lighting brightness and the target activity lighting brightness at the current moment can be clearly set, and then the brightness adaptation factors of all lighting devices in the environment area can be collected and analyzed.
[0095] Furthermore, the target adjusted lighting brightness may be determined by balancing and integrating the influence of the target environment lighting brightness, the target activity lighting brightness, and the device brightness adaptation factor on the target adjusted lighting brightness.
[0096] Specifically, the weight coefficient directly reflects the relative importance of each factor to the final lighting brightness. The weight coefficient corresponding to the target ambient lighting brightness measures the direct impact of ambient light conditions on the adjustment result; the weight coefficient corresponding to the target activity lighting brightness reflects the user's activity demand for the lighting level; and the weight coefficient corresponding to the device brightness adaptation factor ensures that the lighting equipment can be flexibly adjusted according to the actual operating conditions.
[0097] Based on the target lighting brightness adjustment, combined with the actual lighting brightness, the adaptive lighting brightness control strategy is obtained. The expression of the adaptive lighting brightness control strategy is as follows:
[0098]
[0099] Where KZCL t represents the adaptive lighting brightness control strategy at the current time t; TJLD t Indicates the target lighting brightness at the current time t; SJLD t Represents the actual lighting brightness at the current time t.
[0100] The target lighting brightness is determined based on multiple factors such as lighting environment, personnel activities and equipment characteristics, which reflects the optimal brightness level that the lighting system should achieve. The actual lighting brightness reflects the actual brightness output of the lighting system under the current operating state, which is a direct reflection of the system performance and effect.
[0101] Furthermore, by comparing the difference between the target adjusted lighting brightness and the actual lighting brightness, the adaptive lighting brightness control strategy can identify the direction and amplitude of the lighting system that needs to be adjusted, and then trigger the corresponding regulation mechanism to achieve accurate matching and continuous optimization of brightness output, thereby improving the comfort and energy efficiency of the lighting environment, effectively reducing energy consumption, and extending the service life of lighting equipment.
[0102] After obtaining the current lighting energy consumption data, extracting current lighting energy consumption features corresponding to the current lighting energy consumption data;
[0103] Based on the support vector machine, the current lighting energy consumption characteristics are classified, and the corresponding optimization problem is as follows:
[0104]
[0105] In the formula, w u represents the weight vector of the u-th support vector machine, which is used to determine the direction of the classification hyperplane; b u represents the bias term of the u-th support vector machine, which is used to determine the distance between the classification hyperplane and the origin; ξ uvrepresents the slack variable when the vth current lighting energy consumption feature is linearly inseparable in the uth support vector machine; C represents the regularization parameter, which is used to control the trade-off between classification interval and classification error; R represents the total number of current lighting energy consumption features; min represents the minimum value operation.
[0106] The constraints corresponding to the optimization problem are as follows:
[0107] LBBQ v (w u *NHTZ v +b u )≥1-ξ uv ,LBBQ v =u
[0108] LBBQ v (w u *NHTZ v +b u )≤ξ uv -1,LBBQ v ≠u
[0109]
[0110] Where, LBBQ v NHTZ represents the feature category label corresponding to the vth current lighting energy consumption feature; v represents the vth current lighting energy consumption characteristic; w u represents the weight vector of the u-th support vector machine, which is used to determine the direction of the classification hyperplane; b u represents the bias term of the u-th support vector machine, which is used to determine the distance between the classification hyperplane and the origin; ξ uv represents the slack variable when the vth current lighting energy consumption feature is linearly inseparable in the uth support vector machine; R represents the total number of current lighting energy consumption features;
[0111] The feature category label corresponding to the current lighting energy consumption feature is identified, the abnormal lighting energy consumption feature and the corresponding abnormal lighting energy consumption data are determined, and the abnormal lighting energy consumption data is sent to the user end.
[0112] After obtaining the current lighting energy consumption data, the feature extraction step can be further performed to accurately capture the key information in the current lighting energy consumption data, that is, the current lighting energy consumption features. Then, the support vector machine (SVM) can be used to perform feature classification on the current lighting energy consumption features. And according to the feature classification results, the feature category labels corresponding to the current lighting energy consumption features can be discriminated to identify abnormal lighting energy consumption features and their corresponding abnormal lighting energy consumption data.
[0113] like Figure 3As shown, these abnormal data can be sent to the user end in a timely manner through the terminal device, so that the user can take quick measures to optimize the energy consumption performance of the lighting system.
[0114] The strategy optimization and adjustment module is used to obtain the lighting feedback information of the user end, and optimize the adaptive lighting brightness control strategy based on the lighting feedback information and the current lighting energy consumption data, specifically including:
[0115] The user satisfaction data of the user terminal is obtained according to the lighting feedback information, and the first brightness optimization target is set to minimize the current lighting energy consumption data, and the second brightness optimization target is set to maximize the user satisfaction data; based on the first brightness optimization target and the second brightness optimization target, a multi-objective brightness optimization problem corresponding to the adaptive brightness control strategy is determined, and the expression corresponding to the multi-objective brightness optimization problem is as follows:
[0116]
[0117] ZMNH(t)=HJLD t *P t *Δt
[0118] ε ZMNH +ε MYD =1
[0119] Where, HJLD t represents the target environment lighting brightness at the current time t; ε ZMNH Indicates the weight coefficient corresponding to the current lighting energy consumption data; ε MYD represents the weight coefficient corresponding to the user satisfaction data; ZMNH(t) represents the current lighting energy consumption data at the current time t; MYD(HJLD t ) represents the target environment lighting brightness HJLD at the user end t User satisfaction data of P t represents the power of the target lighting device; Δt represents the preset time interval;
[0120] By solving the multi-objective brightness optimization problem, the weight coefficients corresponding to the current lighting energy consumption data and the user satisfaction data are determined respectively, and the adaptive lighting brightness control strategy is optimized and adjusted.
[0121] In practical applications, user satisfaction data can be determined based on lighting feedback information from the user end, which is a key indicator for evaluating the degree of match between lighting effects and user expectations.
[0122] Then, the brightness optimization goals of the multi-objective brightness optimization problem can be set. Specifically, the first brightness optimization goal is to minimize the energy consumption data of the current lighting system; the second brightness optimization goal is to maximize the user satisfaction data, thereby ensuring that the lighting effect can fully meet the actual needs of users.
[0123] Finally, by solving the multi-objective brightness optimization problem, the weight coefficients corresponding to the current lighting energy consumption data and user satisfaction data can be accurately determined, and then the adaptive lighting brightness control strategy can be optimized and adjusted in a targeted manner to ensure that the lighting system can minimize energy consumption while ensuring user satisfaction, thus achieving the best balance between lighting effects and economic benefits.
