Abstract
Description
Technical Field
[0001] This application relates to the technical field of data processing, and particularly to a big data information processing method and system. Background Art
[0002] With the development of modern buildings towards intelligence and energy conservation, precise control and optimized management of the internal environment of buildings have become the key to improving energy efficiency and reducing operating costs. Especially in high-energy-consuming buildings such as large commercial complexes and data centers, how to dynamically adjust the working state of temperature control equipment to adapt to changes in external meteorological conditions while ensuring indoor temperature comfort is one of the important challenges currently faced. In addition, in order to meet increasingly stringent environmental requirements, it is also particularly important to achieve effective management of power loads and reduce unnecessary energy losses.
[0003] Currently, in response to the above technical requirements, data collection and analysis systems based on Internet of Things technology combined with cloud computing platforms have been widely used. This system distributes a variety of sensors (such as temperature sensors, humidity sensors, etc.) in the building to collect various environmental data in the building in real time, and uploads these data to the cloud server for centralized processing. With the help of advanced algorithm models, the system can predict the change trend of heat load in the next period of time, thereby providing a basis for the automatic adjustment of temperature control equipment.
[0004] Although the solutions based on the Internet of Things and cloud computing have improved the building energy management problem to a certain extent, there are still some limitations. First, due to relying on the cloud platform for data analysis, this leads to the problem of data processing delay. Especially in the case of poor network conditions, real-time regulation may not be achieved, affecting the user experience. Second, existing systems often focus on monitoring single types of environmental parameters and lack the comprehensive analysis ability of multi-source heterogeneous data (such as electrical parameters, spatial topology, etc.), making it difficult to comprehensively capture the complex thermal environment characteristics inside the building. Finally, the scalability and flexibility of the system are insufficient. When facing different building structures or special application scenarios, a large amount of custom development work may be required, increasing the implementation difficulty and cost.

The thermal power coupling factor is obtained by superimposing the weighted decay of the thermal resistance parameters and the air flow characteristic data. Finally, the multi-dimensional association rules are generated by jointly analyzing the spectral characteristics of the current data and the geometric topology co-occurrence probability of the heat flow anomaly area, so as to extract the spatio-temporal coupling characteristics of the equipment power consumption and the thermal environment parameters. This method greatly enhances the understanding of the operating state of electrical equipment in a complex thermal environment and its impact on the thermal environment, enabling the system to more accurately identify the key areas and factors causing energy loss. Through the precise positioning and analysis of these key points, not only can the temperature control equipment be more refinedly regulated, but also the energy consumption can be effectively reduced while ensuring comfort, and at the same time, the intelligent level and response efficiency of the entire building energy management system can be improved.

[0065] Figure 1 The following is a flowchart of a big data information processing method provided by an embodiment of the present application. As Figure 1 shown, the method includes:
[0066] 101. Obtain the big data information of the building, where the big data information includes the thermal resistance parameters of the envelope structure and the spatial topology data extracted through the building information model, and combine the thermal distribution map collected by the infrared thermal imaging array to generate an energy distribution model with thermal property marks;
[0067] In this step, the building information model is a digital tool for creating and managing building project information, which contains all the physical and functional characteristic data of the building.
[0068] The thermal resistance parameter of the envelope structure refers to the resistance value of the building envelope such as the exterior wall and roof to heat conduction, and is an important index to measure the heat insulation performance of building materials.
[0069] The spatial topology data describes the internal spatial layout of the building and its mutual relationship, such as the location, size and connection method of the rooms.
[0070] The infrared thermal imaging array is a device that uses infrared technology to capture the temperature distribution on the surface of an object, and the generated thermal distribution map can intuitively display the temperature differences in different areas inside and outside the building.
[0071] The thermal distribution map is an image generated by infrared thermal imaging technology, which shows the temperature distribution on the surface of the object. In the field of architecture, it can be used to identify the abnormal heat flow areas in the building, such as the cold bridge phenomenon around the window or the insulation layer failure points in the wall.
[0072] The energy distribution model is a comprehensive digital model that integrates all the above information and attaches thermal property marks to show the energy flow status inside the building.
[0073] In the embodiments of the present application, first, the thermal resistance parameters and spatial topology data of the building envelope are extracted through a building information model. This process involves using specific software to parse the building design documents to obtain relevant parameters. Then, the building is scanned using an infrared thermal imaging array to collect its thermal distribution map. When processing these data, image processing algorithms are used to identify and label the heat flow abnormal areas, and this information is integrated into the energy distribution model. Finally, combining all the collected data, an energy distribution model containing detailed thermal property information is generated. This model accurately depicts the internal heat distribution of the building and reflects its response characteristics to changes in the external environment.
[0074] In an office building project, first, the building information model software was used to collect the thermal resistance parameters and spatial topology data of the entire building envelope, including the material properties and relative positions of each floor slab and wall. Subsequently, under the cold weather conditions in winter, a high-resolution infrared thermal imaging device was used to conduct a comprehensive scan of the building, obtaining a detailed thermal distribution map, and several obvious cold bridge effects were found around the windows. Based on these data, an energy distribution model that accurately reflects the actual heat flow was constructed, providing a basis for subsequent optimization of the air conditioning system operation.
[0075] 102. Based on the heat conduction path characteristics in the energy distribution model, a set of dynamic heat balance equations is constructed. Through the differential compensation between the temperature field scan data and the simulation results of the set of dynamic heat balance equations, three-dimensional temperature field reconstruction data is generated.
[0076] In this step, the energy distribution model is a comprehensive digital model that integrates all the above information and is attached with thermal property marks to show the energy flow status inside the building.
[0077] The set of dynamic heat balance equations is a set of mathematical expressions used to simulate the heat transfer process in the building, taking into account factors such as the thermal conductivity of building materials and boundary conditions.
[0078] The temperature field scan data is the temperature values at various positions inside the building collected in real time by a sensor network.
[0079] The three-dimensional temperature field reconstruction data is a three-dimensional temperature distribution model after compensation, which more accurately reflects the actual temperature distribution inside the building.
[0080] In the embodiments of the present application, first, based on the heat conduction path characteristics in the energy distribution model, a set of dynamic heat balance equations is established. Then, a distributed temperature sensor network deployed inside the building is used to collect temperature field scan data. By comparing the temperature field scan data with the simulation results of the set of dynamic heat balance equations, the difference points are found and adjusted through a compensation algorithm, and finally, three-dimensional temperature field reconstruction data closer to the actual situation is generated. This step ensures that the temperature field model can truly reflect the actual temperature distribution inside the building.
[0081] Continuing with the data from the previous step, a set of dynamic heat balance equations was established based on the energy distribution model, and a distributed temperature sensor network was deployed to monitor the temperature changes inside the office building in real time. By analyzing the collected data, some local hot spots were found. These areas were finely adjusted using a compensation algorithm, and finally, a three-dimensional temperature field reconstruction model that accurately reflects the actual situation was generated, providing a scientific basis for optimizing the operation of the air conditioning system.
[0082] 103. Input the thermal resistance parameters in the energy distribution model, the coordinates of the heat flux anomaly area in the three-dimensional temperature field reconstruction data, and the current data of the air conditioning unit into the event feature extraction network driven by deep learning to extract the spatio-temporal coupling features of equipment power consumption and thermal environment parameters;
[0083] In this step, the thermal resistance parameters are data describing the resistance of the building envelope (such as walls, windows, etc.) to heat conduction. It reflects the ability of the material to prevent heat transfer and is crucial for evaluating the insulation performance of the building.
[0084] The coordinates of the heat flux anomaly area refer to the position coordinates marked in the three-dimensional temperature field reconstruction data where the temperature is significantly higher or lower than the surrounding area.
[0085] The current data of the air conditioning unit records the current consumption during the operation of the air conditioning system and is one of the important indicators for evaluating equipment power consumption.
[0086] The spatio-temporal coupling features refer to the relationship patterns of these variables changing with time and space, revealing how equipment power consumption responds to different thermal environment conditions.
[0087] In the embodiments of the present application, first, the thermal resistance parameters, the coordinates of the heat flux anomaly area, and the current data of the air conditioning unit in the energy distribution model are input into the event feature extraction network driven by deep learning. The network learns the spatio-temporal coupling features between equipment power consumption and thermal environment parameters through training. This process involves a large amount of data preprocessing, feature engineering, and model training work, and the finally output results help to understand the operating state of the equipment and its impact on the environment.
[0088] Based on the data obtained from the first two steps, a deep learning model was constructed to analyze the energy consumption in different areas of the office building. By continuously monitoring the current consumption of the air conditioning system and the corresponding temperature changes, it was found that the energy consumption increased significantly during certain specific time periods, and the specific reasons for this situation were determined, such as sudden changes in external temperature or increased personnel activities, etc.
[0089] 104. Based on the spatio-temporal coupling characteristics and meteorological forecast data, construct a priority control chain for temperature control equipment, and generate multi-level linkage rules including adjustment of the ventilation rate of fresh air units, optimization of lighting dimming gradients, and triggering of chilled water tank cold release.
[0090] In this step, the spatio-temporal coupling characteristics refer to the relationship patterns of these variables changing over time and space, which reveal how the power consumption of equipment responds to different thermal environment conditions.
[0091] Meteorological forecast data contains weather prediction information for a future period of time, including the change trends of elements such as temperature and humidity.
[0092] The multi-level linkage rules refer to a series of operation instructions set according to different conditions, covering multiple aspects such as adjustment of the ventilation rate of fresh air units and optimization of lighting dimming gradients, aiming to achieve energy-saving goals while ensuring comfort.
[0093] The priority control chain is a series of control strategies formulated based on spatio-temporal coupling characteristics and meteorological forecast data to guide the effective operation of temperature control equipment.
[0094] In the embodiment of the present application, combined with the spatio-temporal coupling characteristics and meteorological forecast data extracted in the above steps, a priority control chain for temperature control equipment is formulated. This chain contains multiple levels of operation instructions, and automatically adjusts the operation status of the equipment according to different climate conditions and indoor requirements. For example, in high-temperature weather, the refrigeration equipment is preferentially started, while in low-temperature conditions, the ventilation volume is appropriately reduced. This not only saves energy but also improves the user experience.
[0095] During the high-temperature warning period in summer, based on the meteorological forecast data, the energy distribution model of the office building, and the reconstructed data of the three-dimensional temperature field, a priority control chain for temperature control equipment was formulated. First, the ventilation rate of the fresh air unit was adjusted to increase night ventilation to reduce the indoor temperature base value, and at the same time, the lighting system dimming gradient was optimized to reduce the light intensity during non-working hours. This series of measures not only reduced the starting pressure of the air conditioning system but also prepared for the upcoming high-temperature weather.
[0096] 105. According to the sensitive node parameters of the priority control chain, dynamically generate a power load smoothing strategy including phase difference control of chilled water pumps, staggered operation of air conditioning groups, and dynamic power limit of emergency lighting.
[0097] In this step, the sensitive node parameters include, but are not limited to, information such as the maximum power of the device, start-up time, and operating mode of the device. By monitoring and analyzing these parameters, effective load management strategies can be formulated.
[0098] The phase difference control of the chilled water pump refers to adjusting the working phase of the chilled water pump motor to optimize its working state and avoid overloading the power grid caused by starting multiple high-power devices simultaneously.
[0099] Staggered operation of the air-conditioning group is a load management technique that arranges different air-conditioning units to operate in different time periods to avoid peak loads caused by all devices starting simultaneously.
[0100] The dynamic power limit of emergency lighting refers to the maximum power limit of the temporary lighting system set to cope with emergencies.
[0101] The power load smoothing strategy is a series of technical means and operating procedures aimed at balancing the relationship between power demand and supply.
[0102] In the embodiment of the present application, based on the priority control chain of the above steps, the power load management strategy is further refined. By real-time monitoring of the sensitive node parameters, the working phase difference of the chilled water pump is dynamically adjusted, the staggered operation plan of the air-conditioning system is implemented, and the power upper limit of the emergency lighting is set. These measures work together to effectively reduce the peak power load and improve the stability of the power grid.
[0103] Based on the priority control chain, the phase difference control is further implemented for the chilled water pumps in the office building, and the air-conditioning groups are arranged to operate in a staggered manner to avoid overloading the power grid caused by all devices starting simultaneously. In addition, the dynamic power limit of the emergency lighting system is set to ensure that the basic lighting requirements can be maintained during peak electricity consumption periods without affecting normal office activities. Through these refined management measures, the peak power load of the office building has been successfully reduced, significantly improving the energy use efficiency and ensuring the power supply stability. These two steps work together to ensure that the office building can still operate efficiently and stably under extreme weather conditions.
[0104] In summary, steps 101 to 105 achieve the refined management and high-efficiency operation of the internal environment of the building. From the initial data collection to the final strategy execution, each step makes full use of modern information technology means to ensure that the building can achieve the best energy-saving effect while meeting the user's needs. This comprehensive solution not only improves the energy utilization efficiency but also enhances the building's ability to adapt to changes in the external environment.
[0105] To further improve the understanding of the spatio-temporal coupling characteristics between equipment power consumption and thermal environment parameters, a spatial correlation map is generated by superimposing the thermal resistance parameters in the energy distribution model and the boundary data of the heat flux anomaly region in the reconstructed three-dimensional temperature field data.

Then, these increment data are superimposed on the original simulated temperature field grid data to construct a more accurate three-dimensional temperature field reconstruction data. Finally, using this improved data, the true temperature distribution of the environment can be more accurately reflected. This process not only improves the accuracy of the simulation results, but also ensures that the temperature field reconstruction data can truly reflect the actual temperature distribution inside the building.

Then, by analyzing the differences between the actual data and the simulated data, local compensation factors were calculated and applied to create continuous compensation field data. On this basis, the technicians further optimized the set of dynamic heat balance equations, and repeatedly adjusted the model parameters through iteration until a satisfactory revised version was obtained. Finally, the original data was enhanced using the revised model to generate three-dimensional temperature field reconstruction data with more details. This not only helps to improve the efficiency of the indoor environment control system in the building, but also provides a scientific basis for energy-saving renovation.

In some embodiments, the step of coupling and iterating the continuously compensated field data with the simulation results of the dynamic heat balance equation set and reversely correcting the heat conduction term of the dynamic heat balance equation set to generate a corrected dynamic heat balance equation set includes:
[0176] 601. Generate node correction coefficients based on the magnitude and direction of the compensation amount in the continuously compensated field data, where the absolute value of the node correction coefficient is positively correlated with the magnitude of the continuously compensated field data;
[0177] In step 601, the continuously compensated field data is a compensated factor distribution map after smoothing and diffusion processing. The compensation amount magnitude refers to the size of the compensation factor, and the direction refers to the direction of the temperature difference. The node correction coefficient is a coefficient generated based on the compensation amount magnitude and direction for adjusting the parameters of the heat conduction equation, and its absolute value is proportional to the compensation amount magnitude. The node correction coefficient is used to correct the errors in the simulation results to make the simulation closer to the actual situation.
[0178] In the embodiments of the present application, first, the compensation amount and its direction required for each node are determined based on the continuously compensated field data. Then, according to the magnitudes and directions of these compensation amounts, the corresponding correction coefficients are calculated for each node. Next, these correction coefficients are applied to the corresponding nodes to ensure that they can accurately reflect the actual temperature change. Finally, by integrating the correction coefficients of all nodes, a node correction coefficient distribution map that comprehensively reflects the temperature field correction requirements is generated.
[0179] 602. Define a heat conduction path weight factor according to the heat conduction path topology relationship of the dynamic heat balance equation set, and perform cross-node conductivity weighted balancing on the node correction coefficients to generate a node correction coefficient distribution;
[0180] In step 602, the heat conduction path topology relationship describes the spatial structure of the heat transfer path inside the building. The heat conduction path weight factor is different weight values assigned to different paths to reflect the importance of the paths. The node correction coefficient distribution is a distribution map generated by performing cross-node conductivity weighted balancing on the node correction coefficients. This distribution map takes into account the mutual influence between different paths and provides a basis for subsequent corrections.
[0181] In the embodiments of the present application, first, the topological relationship of the heat conduction paths in the dynamic heat balance equation set is analyzed to identify the main heat conduction paths. Then, corresponding weight factors are assigned according to the importance of these paths. Next, these weight factors are used to recalculate the correction coefficients of each node to ensure that heat can be evenly distributed throughout the system. Finally, through this process, a distribution map of the node correction coefficients weighted by the conductivity is generated, improving the overall stability of the system.
[0182] 603. Reverse superpose the node correction coefficient distribution with the heat conduction terms of the dynamic heat balance equation set to generate an intermediate correction equation set, and extract the heat flow residual parameters of the intermediate correction equation set and the dynamic heat balance equation set.
[0183] In step 603, the reverse superposition of the heat conduction terms means combining the node correction coefficient distribution with the heat conduction terms of the dynamic heat balance equation set to generate a new equation set. The intermediate correction equation set is the new equation set generated through reverse superposition. The heat flow residual parameter is extracted from the intermediate correction equation set and is an index used to measure the difference between the equation set and the actual temperature field scan data.
[0184] In the embodiments of the present application, first, the node correction coefficient distribution is combined with the heat conduction terms of the dynamic heat balance equation set to form an intermediate correction equation set. Then, the heat flow residual parameters are extracted from this new equation set to evaluate the correction effect. Next, these residual parameters are used to guide the subsequent adjustment work to ensure that the final result is as close to the actual situation as possible. Finally, through the above process, an intermediate correction equation set that can more accurately describe the system behavior is generated.
[0185] 604. Iteratively readjust the node correction coefficient distribution through the heat flow residual parameters until the heat flow residual parameters meet the heat flow conservation constraint conditions of the dynamic heat balance equation set, and generate a corrected dynamic heat balance equation set.
[0186] In step 604, the heat flow residual parameter is an index extracted to measure the difference between the equation set and the actual data. The iterative readjustment means making multiple adjustments to the node correction coefficient distribution according to the heat flow residual parameters until the heat flow conservation constraint conditions are met. The corrected dynamic heat balance equation set is a new equation set generated after multiple iterations of optimization and is used to more accurately simulate the temperature changes inside the building.
[0187] In the embodiments of the present application, first, the node correction coefficient distribution is initially adjusted according to the heat flux residual parameter. Then, this process is repeated multiple times, and each adjustment is based on the latest residual parameter to gradually narrow the error range. Next, it is checked whether the heat flux conservation constraint condition is satisfied during each iteration process. Finally, when the predetermined accuracy requirement is met, a set of corrected dynamic heat balance equations is generated, and this equation set can more accurately simulate the heat conduction behavior of the actual system.
[0188] The following is a specific example:
[0189] In a large data center project, technicians first generate continuous compensation field data based on the data collected by the temperature sensor network, and calculate the correction coefficients of each cooling equipment node accordingly. Then, analyze the topological relationship of the heat conduction paths inside the data center, define appropriate heat conduction path weight factors, and perform conductivity weighted balancing processing on the node correction coefficients. Subsequently, combine the adjusted node correction coefficient distribution with the heat conduction terms of the dynamic heat balance equation set to generate an intermediate correction equation set, and extract the heat flux residual parameter from it. Finally, adjust the node correction coefficient distribution through multiple iterations until the heat flux residual parameter satisfies the heat flux conservation constraint condition, effectively improving the efficiency and stability of the data center cooling system.
[0190] In summary, the accurate understanding and description of the internal temperature field of the building are achieved through steps 601 to 604. This method not only improves the accuracy of temperature field simulation, but also provides a solid foundation for formulating more intelligent and personalized temperature control strategies. By carefully analyzing the heat transfer process inside the building, the overall energy efficiency performance of the building is improved. At the same time, this method enhances the ability to cope with extreme weather conditions, ensuring the comfort and stability of the indoor environment. In addition, this method also improves the response speed and accuracy of the system, making the temperature control management system more efficient and intelligent. Through accurate temperature field reconstruction and correction of the dynamic heat balance equation set, the heat flux distribution inside the building can be better understood, thereby optimizing energy use and improving the comfort of the occupants.
[0191] In order to further improve the intelligence and personalization of the temperature control equipment regulation strategy, the solution constructs a priority regulation chain for the temperature control equipment, using a method that combines spatio-temporal coupling characteristics and meteorological forecast data. First, extract the spatial thermal inertia index and time response sensitivity index of the temperature control equipment, and generate a preliminary priority sequence in combination with the heat conduction path topological relationship. Then, correct the regulation weight through the matching degree between the coverage area and the equipment location to generate a dynamic priority sequence. Finally, iteratively screen out the equipment nodes that violate the energy consumption or stability threshold to construct a priority regulation chain. This method improves the response speed and accuracy of the system. In some embodiments, constructing a priority regulation chain for the temperature control equipment based on the spatio-temporal coupling characteristics and meteorological forecast data in step 104 includes:
[0192] 701. Extract the spatial thermal inertia index and time response sensitivity index of the temperature control device according to the correlation between the distributed thermal inertia parameter of the temperature control device and the future period temperature fluctuation parameter in the meteorological forecast data in the spatio-temporal coupling characteristics.
[0193] In step 701, the spatio-temporal coupling characteristics describe the relationship pattern of device power consumption and thermal environment parameters changing with time and space. The distributed thermal inertia parameter is an index to measure the reaction speed of different positions in the building to temperature changes. The future period temperature fluctuation parameter in the meteorological forecast data provides temperature prediction information for a period of time in the future. The spatial thermal inertia index reflects the resistance ability of each point inside the building to temperature changes, and the time response sensitivity index represents the response speed of the temperature control device to temperature changes.
[0194] In the embodiment of the present application, first, collect the spatial distribution information of the temperature control device and its thermal inertia parameter, and obtain the meteorological forecast data for the future period. Then, extract the spatial thermal inertia index and time response sensitivity index of each temperature control device through a data analysis algorithm (such as regression analysis). Then, evaluate the adaptability of each device to future temperature fluctuations based on these indexes. Finally, integrate all the information to form a data set that comprehensively reflects the adaptability and response speed of the temperature control device.
[0195] 702. Based on the correlation relationship between the spatial thermal inertia index and the time response sensitivity index, establish the regulation influence weight of the temperature control device, and combine the topological relationship of the heat conduction path between the temperature control devices to generate a preliminary priority sequence.
[0196] In step 702, the regulation influence weight is established based on these two indexes and is used to evaluate the influence of each temperature control device in the regulation process. The topological relationship of the heat conduction path describes the heat transfer path between the temperature control devices. The preliminary priority sequence is generated according to the above parameters and relationships to guide the priority ranking of the temperature control devices.
[0197] In the embodiment of the present application, first, calculate the regulation influence weight according to the spatial thermal inertia index and the time response sensitivity index. Then, analyze the topological relationship of the heat conduction path between the temperature control devices to identify the key nodes. Then, use a graph theory algorithm to assign priorities to each device based on the regulation influence weight. Finally, generate a preliminary priority sequence, which considers the interaction between the devices and their importance to the system temperature control.
[0198] 703. According to the spatio-temporal distribution characteristics of extreme temperature events in the meteorological forecast data, dynamically adjust the preliminary priority sequence, and correct the regulation influence weight through the matching degree between the area covered by the extreme temperature event and the spatial position of the temperature control device to generate a dynamic priority sequence.
[0199] In step 703, an extreme temperature event refers to significant high or low temperature weather that may occur within a certain future time period. The spatio-temporal distribution characteristics describe the time and location of the occurrence of these extreme events. The regulation influence weight is further adjusted on this basis. By considering the matching degree between the area covered by the extreme temperature event and the spatial location of the temperature control equipment, a dynamic priority sequence is generated. This sequence is more in line with the actual needs and improves the ability to respond to extreme weather.
[0200] In the embodiment of the present application, first, meteorological forecast data is analyzed to identify possible extreme temperature events in the future and their specific locations and times. Then, the coverage ranges of these events are compared with the locations of the temperature control equipment to evaluate the affected degree. Next, according to the evaluation results, the regulation influence weights of each device are adjusted, and a dynamic priority sequence is re-generated. Finally, it is ensured that this sequence can effectively cope with the upcoming extreme temperature challenges. This process helps to identify the temperature control equipment that most needs to be regulated, improves the system's ability to respond to extreme weather, and ensures the efficient operation of the system.
[0201] 704. By iteratively screening the temperature control equipment nodes in the dynamic priority sequence that violate the energy consumption threshold or the thermal stability threshold, a priority regulation chain for the temperature control equipment is constructed.
[0202] In step 704, the dynamic priority sequence is the adjusted device priority ranking generated in step 703. The energy consumption threshold and the thermal stability threshold are respectively the set upper limit of energy consumption and the minimum temperature requirement for maintaining indoor comfort. By iteratively screening the temperature control equipment nodes in the dynamic priority sequence that violate the above thresholds, a priority regulation chain for the temperature control equipment is constructed. This regulation chain ensures the efficient operation of the system and at the same time meets the comfort requirements of users.
[0203] In the embodiment of the present application, first, the energy consumption and thermal stability thresholds are set as the screening criteria. Then, each device node in the dynamic priority sequence is checked one by one to see if it meets these conditions. Next, the nodes that do not meet the conditions are marked and removed from the sequence or their priorities are rearranged. Finally, a priority regulation chain that meets all the criteria is constructed to ensure the efficient and stable operation of the entire system. The priority regulation chain provides a guarantee for the optimized operation of the temperature control system.
[0204] The following is a specific example:
[0205] In an office building project, technicians first extract the spatial thermal inertia index and time response sensitivity index of each device based on the spatial distribution and thermal inertia parameters of the temperature control devices, combined with the meteorological forecast data for future periods. Then, based on these indices, a regulation influence weight is established, and considering the topological relationship of the heat conduction paths between the temperature control devices, a preliminary priority sequence is generated. Subsequently, extreme temperature events in the meteorological forecast data are analyzed to dynamically adjust the preliminary priority sequence to better cope with extreme weather conditions. Finally, through an iterative screening process, device nodes that violate the energy consumption or thermal stability thresholds are removed, and an efficient priority regulation chain is constructed, significantly improving the response speed and energy utilization efficiency of the temperature control system in the building.
[0206] In summary, through steps 701 to 704, through a series of in-depth data analyses and technical means, an accurate understanding and optimization of the regulation strategy for temperature control devices are achieved. This method not only improves the response speed and accuracy of the temperature control system but also provides a solid foundation for formulating more intelligent and personalized energy-saving strategies. By carefully analyzing the internal heat transfer process of the building and the external meteorological conditions, unnecessary energy losses can be effectively reduced, and the overall energy efficiency performance of the building can be improved. At the same time, this method enhances the ability to cope with extreme weather conditions, ensuring the comfort and stability of the indoor environment. In addition, this method also improves the response speed and accuracy of the system, making the temperature control management system more efficient and intelligent. Through an accurate priority regulation chain, energy consumption can be better managed, and the satisfaction of the occupants can be improved.
