Description

Technical Field

[0001] This application relates to the technical field of heating control, and specifically to a heating zoning control system in a building. Background Art

[0002] With the continuous development of society and economy, people also pay more and more attention to the needs of human comfort and health. The heating demand has naturally become one of the important considerations when choosing a residence. However, due to the reasons of each user, their heating demands may be different. Therefore, this application proposes a heating zoning control system in a building.

[0003] The prior art, such as an invention application patent with the publication number CN114358604A, discloses a time-sharing and zoning regulation method for an urban central heating system considering the heat storage characteristics of a building. Based on methods such as heat load prediction at the heat substation level, heat decay calculation, and heat storage characteristic calculation of the heat substation, each heat substation is divided into several heat decay zones, and the time-sharing characteristics of the heat load demands of each heat substation are summarized; and according to the heat decay situation and heat storage characteristics of each heat substation, a heuristic optimization algorithm is used to obtain an optimized heat substation flow distribution strategy. The method of the present invention can effectively reduce the waste of thermal energy in the heating system and improve the resource utilization efficiency of the system.

[0004] For the above solution, there are the following technical problems: 1. The current technology mainly supplies heat according to the required heat supply of users, without considering the problem that the user demand cannot be met due to heat energy loss during the heating process, nor the problem that the heating effect is different due to the different geographical locations of users. The current neglect of this aspect may lead to the consumption of energy while still being unable to meet the heating demands of users.

[0005] 2. The current technology does not consider the mutual influence problem generated during heating in each region. The current neglect of this aspect will lead to the actual heating amount received by users being much greater than the required heating amount of users, which will further lead to waste of resources and an increase in energy costs, and also cannot bring the best comfort experience to users, and even have a negative impact on the health and quality of life of users. Summary of the Invention

[0006] The purpose of this application is to provide a heating zoning control system in a building, which solves the problems in the background art.

[0007] To solve the above technical problems, this application adopts the following technical solutions: This application provides a heating zoning control system in a building, including a historical information analysis module: used to obtain the heating information corresponding to each user in the building from the data center, analyze and obtain the comprehensive heating quality evaluation coefficient of each user, and then divide each user in the building to obtain each region in the building.

[0008] Heating route analysis module: used to obtain the heating demands of users in each region during the current period from the data center, and then analyze to obtain the heating routes of each region.

[0009] Heat supply quantity analysis module: used to analyze and obtain the total theoretical heating demand and the total heating loss in each region during the current period, so as to analyze and obtain the theoretical heat supply quantity in each region during the current period.

[0010] Heating scheme analysis module: used to formulate the heating scheme in the building during the current period and analyze whether the heating scheme in the building is reasonable.

[0011] Preferably, the heating information includes the heat supply quantities in each historical period, the required room temperatures and the actual room temperatures at each historical detection time point.

[0012] Preferably, the process of dividing each user in the building to obtain each region in the building is as follows: perform a normal distribution on the comprehensive heating quality evaluation coefficients of each user, and obtain the median value after the normal distribution, which is denoted as the standard value of the comprehensive heating quality evaluation coefficient in the building. Compare the comprehensive heating quality evaluation coefficient of each user with the standard value of the comprehensive heating quality evaluation coefficient. When the comprehensive heating quality evaluation coefficient of a certain user is greater than or equal to the standard value of the comprehensive heating quality evaluation coefficient, the region where the user is located is denoted as the secondary priority heating region, otherwise the region where the user is located is denoted as the primary priority heating region. Based on this, each secondary priority heating region and each primary priority heating region in the building are obtained.

[0013] Preferably, the process of obtaining the heating demands of users in each region from the data center and then analyzing to obtain the heating routes of each region is as follows: S1. Based on the user information in each region, obtain whether each user needs heating during the current period, and accordingly obtain each user with heating demand and each user without heating demand.

[0014] S2. Obtain the users with heating demand in the primary priority heating region, denote them as the first-order heating users, and obtain the heating demands of each user adjacent to the first-order heating users. When the heating demand of a certain adjacent user of the first-order heating user is to need heating, denote it as the second-order heating user. Based on this, obtain each second-order heating user of the first-order heating users, and then obtain each second-order heating user of each first-order heating user.

[0015] S3. Obtain the regional division information of each second-order heat supply user. When the region where a certain second-order heat supply user of the first-order heat supply user is located is a first-level priority heat supply region, preferentially use the heat supply pipeline between the first-order heat supply user and this second-order heat supply user for heat supply; otherwise, obtain a second-order heat supply user whose region is a first-level priority heat supply region, and preferentially use the heat supply pipeline between the first-order heat supply user and this second-order heat supply user for heat supply; when a certain first-order heat supply user has no second-order heat supply user, then obtain the user closest to this user in terms of the heat supply pipeline and in need of heat supply as the second-order heat supply user of this user, and conduct heat supply through the pipeline between the two; accordingly, obtain the heat supply routes for each first-level priority heat supply region.

[0016] S4. Repeat the above steps. Similarly, the heat supply routes for each second-level priority heat supply region can be obtained.

[0017] Preferably, the process of formulating the in-building heat supply plan for the current cycle is as follows: Conduct heat supply for each first-level priority heat supply region and each second-level priority heat supply region through their corresponding heat supply routes respectively, and install temperature sensors at the terminals of the heat supply pipelines in each region to obtain the indoor temperatures of each user in each region; when conducting heat supply for each region, monitor the actual heat supply amount and the real-time room temperature in each region. When the real-time room temperature in a certain region reaches the required room temperature, reduce the actual heat supply amount in this region, and mark this region as a region with redundant actual heat supply amount; when the real-time room temperature in a certain region does not reach the required room temperature but the actual heat supply amount has reached the theoretical heat supply amount of this region, transfer the redundant heat supply amount in the region with redundant actual heat supply amount to supply heat to this region, and mark this region as a region with insufficient actual heat supply amount; when the heat supply amount in a certain region reaches the theoretical heat supply amount of this region and the room temperature meets the required room temperature of this region, mark this region as a region with actual heat supply amount meeting the requirements; accordingly, obtain each region with redundant actual heat supply amount, each region with insufficient actual heat supply amount, and each region with actual heat supply amount meeting the requirements.

[0018] Preferably, the process of analyzing whether the in-building heat supply plan is reasonable is as follows: Obtain the theoretical heat supply amount Y of each region k , according to the calculation formula: Analyze and obtain the theoretical heat supply amount Y in the target building for the current cycle.

[0019] After the heat supply for the current cycle ends, respectively obtain the heat supply amounts of each region with redundant actual heat supply amount, each region with insufficient actual heat supply amount, and each region with actual heat supply amount meeting the requirements, and add up the heat supply amounts of each region with redundant actual heat supply amount, each region with insufficient actual heat supply amount, and each region with actual heat supply amount meeting the requirements to obtain the actual heat consumption in the building for the current cycle.

[0020] Compare the actual heat supply consumption in the building during the current period with the theoretical heat supply. If the actual heat supply consumption in the building during the current period is less than the theoretical heat supply, it indicates that the heat supply plan in the building during the current period is reasonable; if the actual heat supply consumption in the building during the current period is greater than the theoretical heat supply, it indicates that the heat supply plan in the building during the current period is unreasonable. If the actual heat supply consumption in the building during the current period is equal to the theoretical heat supply, analyze whether the room temperature in each area with insufficient heat supply reaches the corresponding required room temperature. If the room temperature in a certain area with insufficient heat supply does not reach its corresponding required room temperature, it indicates that the heat supply plan is unreasonable. If the room temperatures in all areas with insufficient heat supply reach their corresponding required room temperatures, then judge that its heat supply plan is reasonable.

[0021] The beneficial effects of this application are as follows: 1. The building heat supply zoning control system provided by this application analyzes the heat supply information of each user in the building in each historical period, and then realizes the zoning of the building. Then, by integrating the heat supply demands of each user in the current period and the zoning of the building, the heat supply routes for each area in the building are analyzed. When determining the heat supply routes, the heat supply pipelines connected to the first-level priority heat supply areas are preferentially selected, which maximally meets the heat supply demands of users in each area while reducing energy consumption. Then, analyze the total theoretical heat supply demand and the total heat supply loss in each area of the building during the current period, so as to formulate the heat supply plan for each area in the building, and realize heat energy scheduling among different areas to ensure the effective utilization of energy, avoiding the problems of overheating for users with redundant actual heat supply and insufficient heat supply for users with insufficient actual heat supply, and greatly ensuring the comfort of users.

[0022] 2. This application comprehensively analyzes the heat supply stability and heat supply quality of each user in the building in each historical period, and then obtains the comprehensive heat supply quality evaluation coefficient of each user, providing a data basis for the subsequent zoning of the building.

[0023] 3. This application divides the areas where each user in the building is located, and then obtains each first-level priority heat supply area and each second-level priority heat supply area, laying a foundation for the subsequent formulation of heat supply routes and heat supply plans. When determining the heat supply routes, the heat supply pipelines connected to the first-level priority heat supply areas are preferentially selected, which effectively improves the heat supply quality of each first-level priority heat supply area, maximally meets the heat supply demands of users in each area while reducing energy consumption, ensures the comfort of users in each area, improves the operation efficiency of the heat supply system, and avoids the heat supply pipelines connected to users who do not need heat supply, so as to avoid bringing a bad heat supply experience to users.

[0024] 4. This application obtains the heating demand of users in each region during the current period, analyzes the heating loss in each region based on the heating situation in the building during each historical period, and then obtains the theoretical heating supply for each region in the current period, providing a data basis for formulating subsequent heating plans. Then, the theoretical heating supply for each region is used as the heating standard to supply heat to each region, and heat scheduling is performed for each region with redundant actual heating supply and each region with insufficient actual heating supply to ensure the effective utilization of energy, avoiding the problems of excessive heating for users with redundant actual heating supply and insufficient heating for users with insufficient actual heating supply. While ensuring user comfort, heat energy waste is avoided. Finally, the actual heating supply and the theoretical heating supply in the building during the current period are compared to analyze whether the heating plan in the building is reasonable, ensuring the rationality and perfection of the heating zoning control system in the building.

Obviously, the drawings in the following description are only some embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0026] Figure 1 It is a schematic connection diagram of the system structure of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0028] Referring to Figure 1 As shown, the present application provides a heating zoning control system in a building, including the following modules: Historical Information Analysis Module: It is used to obtain the heating information corresponding to each user in the building from the data center, analyze to obtain the comprehensive heating quality evaluation coefficient of each user, and then divide each user in the building to obtain each region in the building.

[0029] In a specific example, the heating information includes the heating supply in each historical period, the required room temperature and the actual room temperature at each historical detection time point.

[0030] It should be noted that the heating supply includes the actual heating supply and the required heating supply.

[0031] It should be noted that each historical detection time point is each detection time point in each historical period.

[0032] In a specific example, the comprehensive heating quality evaluation coefficients of each user are obtained through analysis. The specific process is as follows: Based on the heating information of each user in the building, the required heating quantity of each user in each historical period is extracted, and the heating stability evaluation coefficient A i ′ of each user is obtained through analysis, where i represents the number of each user, i = 1, 2......I, and I is any integer greater than 2.

[0033] Based on the heating information of each user in the building, the required room temperature and the actual room temperature of each user at each historical detection time point are extracted, and the heating quality evaluation coefficient A i ″ of each user is obtained through analysis.

[0034] By synthesizing the heating demand evaluation coefficient and the heating quality evaluation coefficient of each user in the building, according to the calculation formula: A i = A i ′ * ζ1 + A i ″ * ζ2, the comprehensive heating quality evaluation coefficient A i of each user in the building is obtained through analysis, where ζ1 and ζ2 respectively represent the weight factors corresponding to heating stability and heating quality.

[0035] It should be noted that 0 < ζ1 < 1, 0 < ζ2 < 1, and ζ1 + ζ2 = 1.

[0036] It should be noted that to obtain the weight factor corresponding to heating stability and the weight factor corresponding to heating quality through factor analysis, first, information condensation of the spatial path attenuation of heating stability data and heating quality data is performed, and then the variance interpretation rate after rotation is obtained. The weight is obtained by dividing the cumulative variance interpretation rate.

[0037] It should be noted that factor analysis is a well-known technology. It is a multivariate statistical analysis method that starts from the study of the internal correlation and dependence relationship of variables and reduces a number of variables with complex relationships to a few comprehensive factors; information condensation is expressed as calculating the median; the variance interpretation rate is the amount of information extracted by the factor, and the variance interpretation rate = eigenvalue / total number of analysis items; the variance interpretation rate after rotation is expressed as the variance interpretation rate of the factor after maximum variance rotation.

[0038] In a specific example, the heating stability evaluation coefficient and the heating quality evaluation coefficient of each user in the building are obtained through analysis. The specific analysis process is as follows: Denote the heating quantity of each user in the building in each historical period as M ij , where j represents the number of each historical period, j = 1, 2......J, and J is any integer greater than 2. According to the calculation formula: The heating stability evaluation coefficient A i ′ of each user in the building is obtained through analysis, where J represents the total number of historical periods, Mi(j-1) Indicates the heat supply of the user numbered i in the (j - 1)-th period.

[0039] It should be noted that the heat supply of each user in each historical period is the actual heat supply of each user.

[0040] It should be noted that the room temperature is affected by factors such as the heat supply, the floor where the user is located, and the daylighting area in the room.

[0041] It should be noted that when j = 1, A i ′ = 0.

[0042] Record the required room temperature and the actual room temperature of each user in the building at each historical time detection point as and where l represents the number of each historical time detection point, l = 1, 2......L, L is any integer greater than 2. According to the calculation formula: Analyze to obtain the heat supply quality evaluation coefficient A i ″ of each user in the building, where L is the total number of detection time points.

[0043] In a specific example, the process of dividing each user in the building to obtain each area in the building is as follows: Perform a normal distribution on the comprehensive heat supply quality evaluation coefficients of each user, and obtain the intermediate value after the normal distribution, which is recorded as the standard value of the comprehensive heat supply quality evaluation coefficient in the building. Compare the comprehensive heat supply quality evaluation coefficient of each user with the standard value of the comprehensive heat supply quality evaluation coefficient. When the comprehensive heat supply quality evaluation coefficient of a certain user is greater than or equal to the standard value of the comprehensive heat supply quality evaluation coefficient, mark the area where the user is located as the secondary priority heating area, otherwise mark the area where the user is located as the primary priority heating area. Based on this, obtain each secondary priority heating area and each primary priority heating area in the building.

[0044] Heat supply route analysis module: Used to obtain the heat supply demands of users in each area in the current period from the data center, and then analyze to obtain the heat supply routes of each area.

[0045] It should be noted that the heat supply demand of users includes the need for heat supply and the lack of need for heat supply.

[0046] In a specific example, the process of obtaining the heat supply demands of users in each area from the data center and then analyzing to obtain the heat supply routes of each area is as follows: S1. Based on the user information of each area, obtain whether each user needs heat supply in the current period, and thus obtain each user with heat supply demand and each user without heat supply demand.

[0047] S2. Obtain the heat - demand users within the first - priority heating area, record them as the first - order heating users, and obtain the heating demands of each user adjacent to the first - order heating users. When the heating demand of a certain adjacent user of the first - order heating user is for heating, record it as the second - order heating user. Based on this, obtain the second - order heating users of each first - order heating user, and further obtain the second - order heating users of each first - order heating user.

[0048] It should be noted that obtaining the heat - demand users within the first - priority heating area is any heat - demand user within the first - priority heating area.

[0049] S3. Obtain the regional - division information of each second - order heating user. When the area where a certain second - order heating user of the first - order heating user is located is the first - priority heating area, preferentially use the heating pipeline between the first - order heating user and this second - order heating user for heating; otherwise, obtain a second - level heating user whose area is the first - priority heating area, and preferentially use the heating pipeline between the first - order heating user and this second - order heating user for heating; when a certain first - order heating user has no second - order heating user, then obtain the user that needs heating and is closest to the heating pipeline of this user as the second - order heating user of this user, and conduct heating through the pipeline between the two; based on this, obtain the heating routes of each first - priority heating area.

[0050] It should be noted that the heating pipeline between the first - order heating user and the second - order heating user will have an impact on both the first - order heating user and the second - order heating user. The heating pipeline preferentially passes through the first - priority heating area to achieve a better heating effect.

[0051] S4. Repeat the above steps. Similarly, the heating routes of each second - priority heating area can be obtained.

[0052] Heat - supply quantity analysis module: used to analyze and obtain the total theoretical heating demand and the total heating loss of each area in the current period, so as to analyze and obtain the theoretical heat - supply quantity of each area in the current period.

[0053] In a specific example, the process of analyzing and obtaining the total theoretical heating demand and the total heating loss of each area in the current period is as follows: Obtain the heating demands of each heat - demand user in each area of the current period from the data center, and record them as where k represents the number of each area, k = 1, 2, and the numbers 1 and 2 represent the numbers of the first - priority heating area and the second - priority heating area respectively, h represents the number of each heat - demand user, h = 1, 2......H. According to the calculation formula: Analyze and obtain the total heating demand Q of each area k, similarly, the total heating demand Q of each region in each historical week can be analyzed and obtained. ik .

[0054] Obtain the actual heat supply of each heat demand user in each historical period from the data center and record it as According to the calculation formula Analyze and obtain the total heating loss N corresponding to each region k .

[0055] It should be noted that the data center is used to store the heating demand, heating information, heating routes, etc. of each region and each user in the building during each period.

[0056] In a specific example, the theoretical heat supply of each region in the current period is analyzed as follows: comprehensively consider the total heating demand Q and the total heating loss N corresponding to each user in each region k , according to the calculation formula: Y k =Q k +N k Analyze and obtain the theoretical heat supply Y of each region k .

[0057] Heating scheme analysis module: used to formulate the heating scheme in the building for the current period and analyze whether the heating scheme in the building is reasonable.

[0058] In a specific example, the process of formulating the heating scheme in the building for the current period is as follows: supply heat to each first-level priority heating region and each second-level priority heating region through their corresponding heating routes, and install temperature sensors at the terminals of the heating pipelines in each region to obtain the indoor temperatures of each user in each region; when supplying heat to each region, monitor the actual heat supply and the real-time room temperature in each region. When the real-time room temperature in a certain region reaches the required room temperature, reduce the actual heat supply in that region and mark that region as a region with redundant actual heat supply; when the real-time room temperature in a certain region does not reach the required room temperature but the actual heat supply has reached the theoretical heat supply of that region, transfer the redundant heat supply of the region with redundant actual heat supply to supply heat to that region and mark that region as a region with insufficient actual heat supply; when the heat supply in a certain region reaches the theoretical heat supply of that region and the room temperature meets the required room temperature of that region, mark that region as a region with actual heat supply meeting the requirements; accordingly, obtain each region with redundant actual heat supply, each region with insufficient actual heat supply, and each region with actual heat supply meeting the requirements.

[0059] It should be noted that the real-time room temperature in a certain region reaching the required room temperature means that the real-time room temperatures of each user in that region all reach the required room temperature.

[0060] In a specific example, the process of analyzing whether the heating scheme in the building is reasonable is as follows: obtain the theoretical heat supply Y of each regionk , according to the calculation formula: Analyze and obtain the theoretical heat supply amount Y in the target building in the current period.

[0061] After the heat supply in the current period ends, obtain the heat supply amounts of each actual heat supply redundant area, each actual heat supply insufficient area, and each actual heat supply compliant area respectively, and add up the heat supply amounts of each actual heat supply redundant area, each actual heat supply insufficient area, and each actual heat supply compliant area to obtain the actual heat consumption in the building in the current period.

[0062] Compare the actual heat consumption in the building in the current period with the theoretical heat supply amount. If the actual heat consumption in the building in the current period is less than the theoretical heat supply amount, it indicates that the heat supply plan in the building in the current period is reasonable; if the actual heat consumption in the building in the current period is greater than the theoretical heat supply amount, it indicates that the heat supply plan in the building in the current period is unreasonable; if the actual heat consumption in the building in the current period is equal to the theoretical heat supply amount, analyze whether the room temperature in each heat supply insufficient area reaches the corresponding required room temperature. If the room temperature in a certain heat supply insufficient area does not reach its corresponding required room temperature, it indicates that the heat supply plan is unreasonable. If the room temperatures in all heat supply insufficient areas reach their corresponding required room temperatures, then judge that its heat supply plan is reasonable.

[0063] The in-building heat supply zoning control system provided by this application analyzes the heat supply information of each user in the building in each historical period, and then realizes the zoning of the building. Then, by integrating the heat supply demands of each user in the current period and the zoning of the building, it analyzes and obtains the heat supply routes for each area in the building. When determining the heat supply routes, it preferentially selects the heat supply pipelines connected to the first-level priority heat supply areas, which maximally meets the heat supply demands of users in each area while reducing energy consumption. Then, it analyzes the total theoretical heat supply demand and the total heat loss in each area of the building in the current period, so as to formulate the heat supply plan for each area in the building, realizes heat energy scheduling among different areas to ensure the effective utilization of energy, avoids the problems of overheating for users with redundant actual heat supply amounts and insufficient heat supply for users with insufficient actual heat supply amounts, and greatly guarantees the comfort of users.

9. The building heating zone control system according to claim 8, characterized in that, The in-building heat supply plan for the current cycle is formulated, and the specific process is as follows: Conduct heat supply to each first-level priority heat supply region and each second-level priority heat supply region through their corresponding heat supply routes respectively, and install temperature sensors at the terminals of the heat supply pipelines in each region to obtain the indoor temperatures of each user in each region; when conducting heat supply to each region, monitor the actual heat supply amount and real-time room temperature of each region. When the real-time room temperature of a certain region reaches the required room temperature, reduce the actual heat supply amount of this region, and mark this region as a region with redundant actual heat supply amount; when the real-time room temperature of a certain region does not reach the required room temperature but the actual heat supply amount has reached the theoretical heat supply amount of this region, transfer the redundant heat supply amount of the region with redundant actual heat supply amount to conduct heat supply to this region, and mark this region as a region with insufficient actual heat supply amount; when the heat supply amount of a certain region reaches the theoretical heat supply amount of this region and the room temperature meets the required room temperature of this region, mark this region as a region with actual heat supply amount meeting the requirements; accordingly, obtain each region with redundant actual heat supply amount, each region with insufficient actual heat supply amount, and each region with actual heat supply amount meeting the requirements.

10. The building heating zone control system according to claim 9, wherein The rationality of the in-building heat supply plan is analyzed, and the specific analysis process is as follows: Obtain the theoretical heat supply amount Y of each area k , according to the calculation formula: Analyze and obtain the theoretical heat supply amount Y in the target building in the current period; After the heat supply in the current cycle ends, obtain the heat supply amounts of each region with redundant actual heat supply amount, each region with insufficient actual heat supply amount, and each region with actual heat supply amount meeting the requirements respectively, and add up the heat supply amounts of each region with redundant actual heat supply amount, each region with insufficient actual heat supply amount, and each region with actual heat supply amount meeting the requirements to obtain the actual heat consumption in the building in the current cycle. Compare the actual heat supply consumption in the building during the current period with the theoretical heat supply. If the actual heat supply consumption in the building during the current period is less than the theoretical heat supply, it indicates that the heat supply plan in the building during the current period is reasonable; if the actual heat supply consumption in the building during the current period is greater than the theoretical heat supply, it indicates that the heat supply plan in the building during the current period is unreasonable; if the actual heat supply consumption in the building during the current period is equal to the theoretical heat supply, analyze whether the room temperature in each area with insufficient heat supply reaches the corresponding required room temperature. If the room temperature in a certain area with insufficient heat supply does not reach its corresponding required room temperature, it indicates that the heat supply plan is unreasonable. If the room temperature in each area with insufficient heat supply reaches its corresponding required room temperature, then judge that its heat supply plan is reasonable.
