Description

Technical Field

[0001] The present invention relates to the technical field of central air-conditioning control, and more specifically, to an intelligent central air-conditioning integrated control method and system based on precise regulation. Background Art

[0002] With the development of HVAC technology, central air conditioning systems have been widely used due to their outstanding performance in efficient energy consumption management and environmental comfort control in large buildings. However, traditional central air conditioning control methods are often based on static preset parameters or simple environmental feedback mechanisms, which are difficult to adapt to the diversity of user needs and the complexity of environmental conditions. The limitations of this control method are significantly reflected in the lack of real-time and accuracy, including the following issues:

[0003] First, the operation and control of traditional central air-conditioning systems mainly rely on single data input from environmental sensors (such as indoor temperature and humidity sensors), which lacks pertinence in perceiving individual user needs. Since individual thermal comfort needs such as user surface temperature are difficult to capture effectively, the adjustment strategy often deviates from actual needs. This "one-size-fits-all" model is not only likely to lead to a decrease in user comfort, but may also lead to energy waste due to unnecessary adjustment actions.

[0004] Secondly, the existing central air conditioning system lacks effective intelligent algorithm support between environmental parameter acquisition and adjustment decision-making. Most systems only use simple rule-based adjustment methods and fail to effectively integrate multi-source data (such as indoor and outdoor temperature, user behavior and usage history data) for optimization decisions. This method is not only rough in calculation and difficult to cope with dynamic changes in the environment, but also easily causes the system operation efficiency to decline due to the lag in parameter adjustment.

[0005] In addition, traditional control methods are usually based on static models, ignoring the dynamics of environmental parameters and user needs. Specifically, the lack of dynamic calculation of the thermodynamic equilibrium between the user's body surface temperature and the ambient temperature makes it difficult for the system regulation effect to achieve the expected effect. For example, when the user's activity intensity, location distribution, or ambient temperature and humidity change drastically, the system cannot quickly adjust the regulation strategy, which can neither guarantee user comfort nor increase equipment loss due to frequent switching of operations.

[0006] Although the closest existing technologies have tried to introduce intelligent means (such as limited fuzzy control or simple neural networks), they still have significant deficiencies in real-time data acquisition, accurate analysis, and dynamic decision optimization. Specifically, the limitations of these technologies are mainly reflected in the following aspects: First, the existing methods cannot comprehensively analyze the synergistic relationship between the user's body surface temperature distribution and the indoor temperature distribution, and the compensation mechanism in the adjustment model is insufficient, making it difficult to achieve precise control; second, the existing image processing technology is out of touch with the air conditioning adjustment mechanism, and it is impossible to form an effective perception-decision-execution closed loop; third, the parameter settings in the algorithm model are single, and dynamic adaptation to various environmental conditions and user behaviors cannot be achieved. Summary of the invention

[0007] In view of the above problems, the present invention starts from the core contradiction of central air-conditioning control and proposes an intelligent central air-conditioning integrated control method and system based on precise adjustment to make up for the shortcomings of the prior art.

[0022] Preferably, the processing steps specifically include:

[0023] According to the connected domain characteristics of the user's body surface pixels, the user's body surface pixels are divided into connected domains using a clustering algorithm, and the saturation value mean and information entropy value in each connected domain are calculated;

[0024] The connected domains whose entropy values ​​are greater than the preset threshold and whose saturation mean values ​​are within the set interval are screened out as the user's body surface areas.

[0025] Preferably, the determination of the average user's body surface temperature further comprises:

[0026] Calculate the temperature difference of each pixel by combining the Euclidean distance between the user's contour pixel and the geometric center point;

[0027] The temperature distribution of the user's body surface pixels is fitted and corrected through the neural network model.

[0028] Preferably, the determination of the compensation temperature specifically includes:

[0029] Generate a compensated temperature image according to the compensated temperature value of each pixel in the indoor temperature distribution image;

[0030] Based on the compensated temperature image, the compensated mean is calculated as the final compensated temperature.

[0031] Preferably, the compensation adjustment of the user temperature adjustment model specifically includes:

[0032] Add each pixel value in the compensation image to the corresponding pixel value of the indoor temperature distribution image to generate a new temperature distribution image;

[0033] According to the new temperature distribution image, the operating parameters of the intelligent central air conditioner are adjusted, including the air outlet temperature and wind speed.

[0035] The user's comfortable temperature is generated based on the difference between the average user's body surface temperature and the average indoor temperature, combined with a preset temperature comfort model;

[0036] The temperature comfort model includes an outdoor temperature weight, a humidity weight and a user personalized adjustment factor.

[0037] As a preference, it further comprises:

[0038] Analyze historical operating data and dynamically update the weight factors of the temperature comfort model to adapt it to different seasons and environmental conditions.

[0039] As a preference, it further comprises:

[0040] When the user is not indoors, the central air-conditioning operating parameters are optimized and the energy-saving mode is entered based on the outdoor temperature prediction model.

[0041] An intelligent central air-conditioning integrated control system based on precise regulation for executing the method described in the claims comprises:

[0042] Image acquisition module, used to obtain user's indoor image data and indoor temperature distribution data;

[0048] The technical problem to be solved by the present invention is how to achieve accurate perception and dynamic response of the central air-conditioning system to the individual needs of users and changes in the indoor environment. By constructing a control mechanism based on image processing and multi-dimensional data analysis, the present invention not only effectively solves the contradiction between user comfort and energy efficiency in traditional methods, but also realizes the complementarity and coordinated optimization of multiple steps through algorithm design. For example, the clustering and screening mechanism of user surface temperature makes the extraction of user temperature features more accurate through clustering analysis based on HSV color space and connected domain screening technology; at the same time, the compensation mechanism of indoor and outdoor temperatures works together with the dynamic adjustment model to perform real-time compensation by calculating the difference between user surface temperature and indoor temperature, which significantly improves the accuracy of comfort calculation.

[0049] In terms of the collaborative design of steps and algorithms, the present invention enables the system to adaptively adjust under different environmental conditions through the superposition optimization of compensation temperature and intelligent adjustment model. For example, the calculation of compensation temperature not only integrates the user's body surface temperature distribution and indoor temperature distribution, but also fits and corrects the dynamic temperature distribution through neural network to form a complete perception-feedback closed loop. At the same time, the control instructions generated in the output stage further enhance the stability and accuracy of the adjustment effect by optimizing the operating parameters of the air conditioner (such as outlet temperature and wind speed) in real time.

[0050] The beneficial effects of the present invention are mainly reflected in the following aspects:

[0061] Please refer to Figure 1-5 The present invention provides an intelligent central air-conditioning integrated control method based on precise regulation, comprising:

[0062] The acquisition steps include:

[0063] Acquire user indoor image data and indoor temperature distribution data, wherein the user indoor image data is used to reflect the user's body surface temperature characteristics, and the indoor temperature distribution data is used to reflect the ambient temperature changes;

[0064] Obtain user historical usage data, including user preferred temperature settings, air conditioning operating modes, and time periods.

[0065] Processing steps include:

[0066] Based on the user's indoor image data, convert it from the RGB color space to the HSV color space, determine the brightness value of each pixel point and perform cluster analysis, screen out the user's body surface pixels, and generate the user's body surface temperature distribution image;

[0067] Determine the user's body surface temperature mean and the indoor temperature mean according to the indoor temperature distribution data and the user's body surface temperature distribution image, and further determine the compensation temperature;

[0068] Based on the compensation temperature, a compensation adjustment is performed on a preset user temperature adjustment model.

[0069] Output steps include:

[0070] Output compensated user comfort temperature;

[0071] Based on the user's comfortable temperature, control instructions for precise adjustment of the central air conditioner are generated to optimize the air conditioner operating parameters in real time.

[0072] In a preferred embodiment of the present invention, the image acquisition module 1 acquires indoor image data, which reflects the user's body surface temperature characteristics, such as the size and distribution of the body surface heat dissipation area; at the same time, the temperature sensor module 2 acquires indoor temperature distribution data to reflect the dynamic change characteristics of the ambient temperature. The user's historical usage data is recorded by the data storage module 3, including the user's preferred temperature range, usage frequency and mode under different environmental conditions.

[0073] Preferably, in the method of the present invention, the HSV color space conversion of the image data adopts the following formula:

[0074]

[0075] Among them, H is the hue value, R, G, B are the red, green and blue values ​​of the pixel, and Δ is the difference between the maximum and minimum values. The hue value and brightness value of the pixel are classified by clustering algorithm, and combined with the brightness threshold (preferably 0.5, according to experience, this value can effectively avoid misjudgment of dark areas), the user's body surface pixels are accurately screened. In the output stage, the average user surface temperature and the average indoor temperature are calculated by the formula:

[0076]

[0077] Among them, T comp To compensate for temperature, is the user's body surface temperature pixel value, is the indoor temperature pixel value, n and m are the number of surface temperature pixels and indoor temperature pixels respectively. The generated compensation temperature is used to dynamically adjust the user's comfortable temperature through the temperature adjustment model.

[0078] This step combines the user's actual needs with the dynamic changes in the environment through precise image data analysis and multi-dimensional temperature compensation calculations, making the control of central air conditioning more efficient and accurate.

[0079] In one embodiment of the present invention, the obtaining step further comprises:

[0080] Get outdoor environment temperature and humidity data;

[0081] The outdoor environment data is used as a weight factor to adjust the parameters in the user temperature adjustment model.

[0082] Preferably, in one embodiment of the present invention, outdoor temperature and humidity data are acquired in real time by the environmental data acquisition module 4. For example, when the outdoor temperature is lower than 10°C, the weight factor of the indoor conditioning model is automatically adjusted to:

[0083] W outdoor =0.8 (empirical value at low temperature)

[0084] When the humidity is above 70%, the humidity weighting factor is set to:

[0085] W humidtity =1.2 (empirical value under high humidity conditions)

[0086] These data are adjusted through dynamic weights, and the calculation formula for the user's comfortable temperature in the optimized temperature regulation model is:

[0087] T comfort =W outdoor ·T outdoor +W humidity ·H+W indoor ·T indoor

[0088] Among them, T comfort is the calculated user comfort temperature, T o utdoor,T indoor are the outdoor and indoor temperatures respectively, H is the humidity,

[0089] W outdoor W humidity ,W indoor They are dynamic weights respectively.

[0090] This method further improves the accuracy of user comfort and the adaptability of the model by increasing the dynamic influence of outdoor environmental parameters, making the operation of central air conditioning more in line with actual environmental requirements.

[0091] In one embodiment of the present invention, the processing steps specifically include:

[0092] According to the connected domain characteristics of the user's body surface pixels, the user's body surface pixels are divided into connected domains using a clustering algorithm, and the saturation value mean and information entropy value in each connected domain are calculated;

[0093] The connected domains whose entropy values ​​are greater than the preset threshold and whose saturation mean values ​​are within the set interval are screened out as the user's body surface areas.

[0094] In a preferred embodiment of the present invention, based on the image connected domain algorithm, the connectivity between pixels is determined by calculating the Euclidean distance between adjacent pixels:

[0095]

[0096] Among them, d ij is the Euclidean distance between pixel points i and j, and x and y are pixel coordinates. ij <∈ (preferably, ∈=3 pixels, and this threshold is suitable for most scenes according to empirical values), then the two points belong to the same connected domain.

[0097] The entropy calculation formula for each connected domain is:

[0098]

[0099] Among them, E is the entropy value, p i is the probability density of the ith pixel in the connected domain, and n is the total number of pixels in the connected domain. By screening the connected domains with entropy values ​​greater than 2.5 and combining the condition that the saturation value mean is between 0.6 and 0.9, the user's body surface area can be effectively identified.

[0100] Through connected domain analysis and multi-condition screening, the accuracy of user body surface area extraction is significantly improved, providing more reliable data support for subsequent temperature compensation calculations.

[0101] In a preferred embodiment of the present invention, the determination of the average user's body surface temperature further includes:

[0102] Calculate the temperature difference of each pixel by combining the Euclidean distance between the user's contour pixel and the geometric center point;

[0103] The temperature distribution of the user's body surface pixels is fitted and corrected through the neural network model.

[0104] In a preferred embodiment of the present invention, firstly, based on the distribution of the pixels on the user's body surface, the Euclidean distance from the user's contour pixels to the geometric center point is calculated. The coordinates of the geometric center point are determined by the following formula:

[0105]

[0106] Among them, (x c ,y c ) is the coordinate of the geometric center point, x i ,y i is the coordinate of each body surface pixel point, and n is the total number of user body surface pixels. The Euclidean distance of each pixel point is calculated as:

[0107]

[0108] Among them, d i is the Euclidean distance from pixel i to the geometric center. By calculating the temperature difference of each pixel:

[0109] ΔT i =T i -T avg

[0110] Among them, T i is the temperature value of pixel i, T avg It is the preliminarily calculated average user's body surface temperature.

[0111] Preferably, the method combines a neural network model to fit and correct the distribution of the user's body surface temperature. The input of the model is the Euclidean distance and the temperature difference of the pixel point, and the output is the corrected temperature value. The loss function of the neural network is defined as:

[0112]

[0113] Among them, T′ i is the output temperature value of the neural network, T i is the actual measurement value, and the goal of the loss function is to minimize the fitting error.

[0114] Through the distance calculation of the geometric center point and the fitting correction of the neural network, this method can effectively eliminate the influence of the deviation between pixel points, make the calculation of the user's body surface temperature more accurate, and provide high-precision basic data for subsequent temperature compensation.

[0115] In a preferred embodiment of the present invention, the determination of the compensation temperature specifically includes:

[0116] Generate a compensated temperature image according to the compensated temperature value of each pixel in the indoor temperature distribution image;

[0117] Based on the compensated temperature image, the compensated mean is calculated as the final compensated temperature.

[0118] In a preferred embodiment of the present invention, the compensation temperature determination process first needs to process the indoor temperature distribution image and calculate the compensation temperature value of each pixel. The specific formula is as follows:

[0119] T comp (xy) = T room (x,y)+ΔT user

[0120] Among them, T comp (x, y) is the temperature value of the pixel (x, y) in the compensated temperature image, T room (x, y) is the temperature value of the corresponding pixel in the indoor temperature distribution image, ΔT user It is the compensation value of the user's body surface temperature.

[0121] Next, based on the compensated temperature values ​​of all pixels, the compensated mean is calculated:

[0122]

[0123] Among them, T comp_avg is the final compensated temperature, and m is the total number of pixels in the compensated temperature image.

[0124] By generating a compensated temperature image and calculating its mean, this method can dynamically reflect the comprehensive difference between the indoor temperature distribution and the user's body surface temperature, making the calculation of the compensated temperature more holistic and real-time, and ensuring a more accurate central air-conditioning adjustment effect.

[0125] In a preferred embodiment of the present invention, the compensation adjustment of the user temperature adjustment model specifically includes:

[0126] Add each pixel value in the compensation image to the corresponding pixel value of the indoor temperature distribution image to generate a new temperature distribution image;

[0127] According to the new temperature distribution image, the operating parameters of the intelligent central air conditioner are adjusted, including the air outlet temperature and wind speed.

[0128] Preferably, in the method of the present invention, the compensation adjustment process first superimposes the compensated temperature image and the indoor temperature distribution image pixel by pixel to form a new temperature distribution image, the formula of which is:

[0129] T new (xy) = T comp (x,y)+T room (x,y)

[0130] Among them, T new (x, y) is the temperature value of the pixel (x, y) in the new temperature distribution image, T comp (x,y) and T room (x, y) are the temperature values ​​of the corresponding pixels in the compensated temperature image and the indoor temperature distribution image respectively.

[0131] According to the new temperature distribution image, the intelligent central air conditioner adjusts the air outlet temperature and wind speed through the operating parameter adjustment module. Preferably, when the highest temperature point in the new temperature distribution image is higher than the set threshold (such as 28°C, based on the experience value of the user's comfortable temperature), the system will reduce the air outlet temperature to 22°C and increase the wind speed to level 3 (the experience value is suitable for rapid heat dissipation). On the contrary, when the lowest temperature point is lower than the set threshold (such as 18°C), the air outlet temperature will be adjusted to 26°C and the wind speed will be reduced to level 1.

[0132] By superimposing the compensation image and the indoor temperature distribution image and adjusting the operating parameters of the central air conditioner in real time, the method can quickly respond to environmental changes and provide users with a more comfortable indoor environment.

[0133] In a preferred embodiment of the present invention, the generation of the comfortable temperature specifically includes: generating the user comfortable temperature according to the difference between the average value of the user's body surface temperature and the average value of the indoor temperature in combination with a preset temperature comfort model;

[0134] The temperature comfort model includes an outdoor temperature weight, a humidity weight and a user personalized adjustment factor.

[0135] In a preferred embodiment of the present invention, the generation of user comfort temperature is based on the following temperature comfort model:

[0136] T comfort =w outdoor ·T outdoor +w humidity ·H+w indoor ·T indoor +w user ΔT user

[0137] Among them, T comfort For user comfort temperature, T outdoor , T indoor are the outdoor and indoor temperatures respectively, H is the humidity, ΔT user is the difference between the user's body temperature and the room temperature; w outdoor 、w humidity ,w indoor 、w user is the corresponding weight factor.

[0138] Preferably, the initial value of the weight factor is set empirically as:

[0139] w outdoor =0.2,w humidity =0.3,w indoor =0.4,w user =0.1

[0140] The system dynamically adjusts weight factors based on environmental changes and user historical preferences to ensure the adaptability of comfortable temperature generation.

[0141] By comprehensively considering multi-dimensional environmental data and user personalized needs, the temperature comfort model of this method can accurately generate user comfort temperature and improve the intelligence level of central air-conditioning control and user experience.

[0142] In a preferred embodiment of the present invention, it further comprises: analyzing historical operation data and dynamically updating the weight factors of the temperature comfort model to adapt it to different seasons and environmental conditions.

[0143] In a preferred embodiment of the present invention, the system dynamically collects historical operation data, including indoor and outdoor temperature, humidity, and user actual adjustment parameters, through the operation log unit. Based on these data, a dynamic weight update algorithm based on recursive least squares (RLS) is used to adjust the weight factors in the temperature comfort model.

[0144] Preferably, the core algorithm for dynamic weight update is as follows:

[0145]

[0146]

[0147] Among them, w t is the current weight factor vector, P t is the update matrix, x t is the input feature vector (such as outdoor temperature, humidity and user surface temperature data), y t is the actual comfort data, λ is the forgetting factor, which is usually set to 0.95 to retain the influence of recent data.

[0148] Preferably, the method uses the above algorithm to adjust the weight factor in seasonal changes (such as high outdoor temperature and high humidity in summer) and dynamic environmental fluctuations (such as sudden temperature drop), so that the output of the temperature comfort model is closer to the actual needs of users.

[0149] By introducing the recursive least squares method to dynamically adjust the model weights, this method can effectively adapt to changes in the environment and user needs during long-term operation, thereby improving the intelligence level of the system and user comfort.

[0150] In a preferred embodiment of the present invention, it further includes: when the user is not indoors, combining the outdoor temperature prediction model, optimizing the central air-conditioning operating parameters and entering the energy-saving mode.

[0151] The method of the present invention preferably includes two main processes: user detection and air conditioning operation state optimization. When the system detects that the user has left the room, the user behavior detection module is used to identify the indoor unmanned state, and then the air conditioning operation parameters are adjusted in combination with the outdoor temperature prediction model to put the system into energy-saving mode.

[0152] Preferably, the outdoor temperature prediction model adopts a time series prediction method and uses an ARIMA model, the core formula of which is:

[0153]

[0154] Among them, T t is the outdoor temperature at the predicted time point, φ i is the AR part coefficient, θ j is the MA part coefficient, ∈ t is the noise term, p and q are the lag order and moving average order respectively.

[0155] In energy saving mode, the following operating parameters are preferably set:

[0156] The upper limit of the air outlet temperature is adjusted to 28°C, which is suitable for energy-saving mode when the user is away;

[0157] The wind speed is reduced to level 1 to reduce energy consumption;

[0158] If the predicted outdoor temperature is lower than 15°C, the cooling function is turned off and only the ventilation function is turned on.

[0159] By combining user behavior detection with the outdoor temperature prediction model, this method can effectively reduce energy consumption in an unmanned state while maintaining suitable basic indoor environmental conditions, taking into account both energy saving and actual needs.

[0161] Image acquisition module 1, used to obtain user's indoor image data and indoor temperature distribution data;

[0162] A data processing module 2, configured to generate a user's body surface temperature distribution image based on the user's indoor image data, and determine a compensation temperature based on the indoor temperature distribution data and the user's body surface temperature distribution image;

[0163] An adjustment model module 3, used for compensating and adjusting the user temperature adjustment model based on the compensation temperature;

[0164] A control module 4, used for generating an operation control instruction of the central air conditioner according to the compensated user comfort temperature;

[0165] The data storage module 5 is used to store the user's historical usage data and the air conditioner operation log to optimize the subsequent adjustment strategy.

[0166] The system of the present invention comprises an image acquisition module 1, which is connected to a high-resolution camera device, preferably equipped with an infrared thermal imaging sensor, for collecting user surface temperature and indoor temperature distribution data. The data processing module 2 processes the collected data into a user surface temperature distribution image through a built-in clustering algorithm and a neural network model, and further calculates the compensation temperature in combination with the indoor temperature distribution image.

[0167] The adjustment model module 3 preferably includes a dynamic adjustment unit, which receives the compensation temperature from the data processing module and makes compensation adjustments to the temperature adjustment model according to the user's historical usage data and environmental parameters. The control module 4 optimizes the operation status of the central air conditioner in real time by generating specific operation control instructions (such as adjusting the air outlet temperature and wind speed). The data storage module 5 is used to store user historical data and operation logs, and preferably also includes a remote synchronization function based on the cloud to ensure the sharing of operation data among multiple devices.

[0168] Through multi-module collaboration, the system achieves precise regulation and intelligent control, especially the user comfort temperature calculation and energy-saving strategy based on dynamic adjustment, which fully improves the intelligence level and user experience of the central air-conditioning system, and provides comprehensive technical support for energy saving and user comfort.
