[0043] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0044] Traditional heating systems have the problem of unstable operation. This will affect the heating quality and indoor comfort. However, with the acceleration of urbanization and the improvement of people's living standards, people's requirements for heating quality and indoor comfort are getting higher and higher. This will lead to the need to adjust the heating status of the heating system when the heating is not suitable to improve the heating quality.

[0045] In view of the above situation, the present disclosure provides a distributed heating state control method, which is applied to a multi-heat exchange station heating system. Figure 1 FIG. 1 is a flow chart of a distributed heating state control method according to an exemplary embodiment. Figure 1 As shown, the distributed heating state control method includes:

[0046] Step 10, obtaining the average indoor temperature corresponding to each target area within the first predetermined time period when the distributed heating system is heating, wherein each target area includes a plurality of heat supply and exchange units;

[0047] Step 11: determining the compliance of heating in each target area based on the average indoor temperature corresponding to each target area within the first predetermined time period and the upper and lower limits of the indoor temperature;

[0048] Step 12: If there is a target area in each target area where the regional heating fails to meet the standard, then based on the indoor temperature at each moment within the second predetermined time period in the target area where the heating fails to meet the standard, a temperature change trend graph of the indoor temperature at each moment within the second predetermined time period in the target area where the heating fails to meet the standard is obtained; wherein the first predetermined time period is greater than the second predetermined time period, and the temperature change trend graph at least represents the change trend of the number of heating failure moments, heating standard meeting moments, and heating excess moments corresponding to the heating cells supplied by each heat supply and exchange unit in the target area where the heating fails to meet the standard within the second predetermined time period;

[0049] Step 13: Based on the temperature change trend diagram obtained from the indoor temperature at each moment within the second predetermined time period in the target area that has not reached the standard, a heating status diagnosis of each heat supply and exchange unit in the target area that has not reached the standard is performed to obtain a heating status diagnosis result of each heat supply and exchange unit in the target area that has not reached the standard;

[0050] Step 14: Based on the diagnosis result of the heating status of each heat supply and exchange unit in the target area that does not meet the standard, adjust the heating status of each heat supply and exchange unit in the target area that does not meet the standard.

[0051] In this exemplary embodiment, the first predetermined time is greater than the second predetermined time. When determining the target area in each target area where the heating does not meet the standard, the average indoor temperature corresponding to each target area within the first predetermined time can be collected. The first predetermined time can be indoor temperature data for half a month, a week, or nearly two to three days. The second predetermined time can be a day within half a month or a week.

[0052] In this exemplary embodiment, when collecting indoor temperatures at each moment within the second predetermined time period in the target area that does not meet the standard, data collection can be performed at each moment within each hour within the second predetermined time period. For example, the indoor temperature from 8:01:05 to 8:02:05, the indoor temperature from 10:01:05 to 10:02:05, the indoor temperature from 12:01:05 to 12:02:05, the indoor temperature from 14:01:05 to 14:02:05, and so on, is collected in each of the 10 hours of the dth day. Then, a temperature change trend graph of the indoor temperature at each moment within the second predetermined time period in the target area that does not meet the standard is obtained through these indoor temperature collection data; wherein the temperature change trend graph at least represents the change trend of the number of heating non-standard moments, the number of heating standard moments, and the number of heating exceeding standard moments corresponding to the heating cells supplied by each heat supply and exchange unit in the target area that does not meet the standard within the second predetermined time period. Through the temperature change trend diagram of the indoor temperature, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is diagnosed, and the heating status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard is obtained; based on the heating status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is regulated, which is beneficial to improving the heating quality of the heat supply and exchange unit in the target area that does not meet the standard.

[0053] In some embodiments, determining the compliance of heating in each target area based on the average indoor temperature corresponding to each target area within the first predetermined time period and the upper and lower limits of the indoor temperature includes:

[0054] If there is a target area in each of the target areas whose corresponding average indoor temperature within the first predetermined time period is lower than the lower limit of the indoor temperature, the target area whose average indoor temperature is lower than the lower limit of the indoor temperature is determined as the target area where heating fails to meet the standard;

[0055] If there is a target area in each target area where the average indoor temperature within the first predetermined time period is higher than the upper limit of the indoor temperature, the target area where the average indoor temperature is higher than the upper limit of the indoor temperature is determined as the target area where the heating supply exceeds the standard;

[0056] If there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is between the upper and lower limits of the indoor temperature, the target area whose average indoor temperature is between the upper and lower limits of the indoor temperature is determined as the target area where heating meets the standard.

[0057] In this exemplary embodiment, when determining whether the heating of a target area meets or fails to meet or exceeds the standard, if there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is lower than the lower limit of the indoor temperature, then the target area with an average indoor temperature lower than the lower limit of the indoor temperature is determined as the target area where the heating standard does not meet; if there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is higher than the upper limit of the indoor temperature, then the target area with an average indoor temperature higher than the upper limit of the indoor temperature is determined as the target area where the heating standard exceeds; if there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is between the upper and lower limits of the indoor temperature, then the target area with an average indoor temperature between the upper and lower limits of the indoor temperature is determined as the target area where the heating standard meets.

[0058] In this exemplary embodiment, the upper and lower limits of the indoor temperature can be set as needed. For example, if the upper limit of the indoor temperature is 26°C and the lower limit of the indoor temperature is 18°C, then if there is a target area in each target area where the average indoor temperature is lower than the lower limit of the indoor temperature by 18°C, then the target area where the average indoor temperature is lower than the lower limit of the indoor temperature by 18°C ​​is determined as the target area where the heating fails to meet the standard; if there is a target area in each target area where the average indoor temperature is higher than the upper limit of the indoor temperature by 26°C, then the target area where the average indoor temperature is higher than the upper limit of the indoor temperature by 26°C is determined as the target area where the heating exceeds the standard; if there is a target area in each target area where the average indoor temperature is between the upper and lower limits of the indoor temperature, then the target area where the average indoor temperature is between the upper and lower limits of the indoor temperature (18°C to 26°C) is determined as the target area where the heating meets the standard, which is conducive to determining the target area where the heating fails to meet the standard.

[0059] In this exemplary embodiment, determining whether the heating of each target area meets the standard further includes:

[0060] Determine the average indoor temperature for each target area;

[0061] Based on the average indoor temperature of each target area, the heating compliance rate, heating non-compliance rate and heating excess rate of each target area are determined.

[0062] Determine the heating compliance rate for each target area, including:

[0063] is the indoor temperature failure rate of the i-th target area, n i不is the number of hours that the indoor temperature of the i-th target area does not meet the standard, n i The total time length for temperature collection of the i-th target area;

[0064] n i达 is the total number of hours that the indoor temperature of the i-th target area meets the standard, n i is the total time length of temperature collection in the i-th target area, is the indoor temperature non-compliance rate of the i-th target area;

[0065] n i超 is the total number of hours that the indoor temperature of the i-th target area exceeds the standard, n i is the total time length of temperature collection in the i-th target area, is the indoor temperature exceeding standard rate of the i-th target area;

[0066] Among them, when obtaining the average indoor temperature of the i-th target area,

[0067] is the average indoor temperature of the i-th target area;

[0068] T ij is the average indoor temperature of the i-th target area at the j-th moment;

[0069] n i The total time length for temperature acquisition of the i-th target area.

[0070] In some embodiments, the indoor temperature at each moment within the second predetermined time period in the target area where the heating supply fails to meet the standard is obtained based on the indoor temperature at each moment within the second predetermined time period in the target area where the heating supply fails to meet the standard, comprising:

[0071] Obtain multiple indoor average temperatures collected at multiple times within n hours on the dth day for the residential area heated by each heat supply and exchange unit in the target area that has not reached the target; wherein one time corresponds to one indoor average temperature; multiple time temperature collections are performed within each hour; d≥1, n≥2;

[0072] Based on multiple average indoor temperatures collected at multiple times on the dth day for the cells heated by each heat supply and exchange unit in the target area that did not meet the standard, and the average indoor temperature on the dth day, determine the time period when the heating did not meet the standard, the time period when the heating met the standard, and the time period when the heating exceeded the standard for the cells heated by each heat supply and exchange unit in the target area that did not meet the standard on the dth day;

[0073] Based on the time periods when the heating supply does not meet the standard, the time periods when the heating supply meets the standard and the time periods when the heating supply exceeds the standard on the d day for the cell heated by each heat exchange unit in the target area that does not meet the standard, a temperature change trend graph of the indoor temperature of the cell heated by each heat exchange unit in the target area that does not meet the standard at each moment within the second predetermined time period is obtained.

[0074] In this exemplary embodiment, when determining the heating conditions of the heat exchange units in the target area where the heating standard is not met, a plurality of indoor average temperatures collected at multiple times within n hours on the d day for the cells heated by each heat exchange unit in the target area where the standard is not met can be first obtained. Then, based on the plurality of indoor average temperatures collected at multiple times on the d day for the cells heated by each heat exchange unit in the target area where the standard is not met and the average indoor temperature on the d day, the time period during which the heating standard is not met for the cells heated by each heat exchange unit in the target area where the standard is not met and the time period during which the heating standard is not met for the cells on the d day can be determined. The time periods when the heating supply meets the standard and the time periods when the heating supply exceeds the standard, and finally, based on the time periods when the heating supply does not meet the standard, the time periods when the heating supply meets the standard and the time periods when the heating supply exceeds the standard on the d day for the community heated by each heat exchange unit in the target area that does not meet the standard, a temperature change trend graph of the indoor temperature of the community heated by each heat exchange unit in the target area that does not meet the standard at each moment within the second predetermined time period is obtained. In this way, a temperature change trend graph that can accurately reflect the heating situation of the heat exchange units in the target area that does not meet the standard can be obtained, thereby providing an effective basis for diagnosing the heating status of each heat exchange unit in the target area that does not meet the standard.

[0075] In some embodiments, based on the time period during which the heating supply does not meet the standard, the time period during which the heating supply meets the standard, and the time period during which the heating supply exceeds the standard on the dth day, a temperature change trend graph of the indoor temperature of the cell heated by each heat supply and exchange unit in the target area that does not meet the standard is obtained at each moment within the second predetermined time period, includes:

[0076] Based on the time periods during which the heating did not meet the standard, the time periods during which the heating met the standard, and the time periods during which the heating exceeded the standard on the d day for the community heated by each heat exchange unit in the target area that did not meet the standard, combined with the temperature change of the outdoor room temperature over n hours on the d day, the distance from the community heated by each heat exchange unit to the corresponding heat exchange unit, and the aging degree of the heating pipeline from the heat exchange unit to the heating community, a temperature change trend graph of the indoor temperature at each moment within the second predetermined time period for the community heated by each heat exchange unit in the target area that did not meet the standard is determined; wherein the temperature change trend graph is at least annotated with the temperature change information corresponding to the temperature change of the outdoor room temperature over n hours on the d day, the distance information from the community heated by each heat exchange unit to the corresponding heat exchange unit, and the aging degree information of the heating pipeline from the heat exchange unit to the heating community.

[0077] In this exemplary embodiment, when determining the temperature change trend graph, in order to better reflect the heating status of the heat supply and exchange unit, when determining the temperature change trend graph, the temperature change trend graph of the indoor temperature of each heat supply and exchange unit in the target area that does not meet the standard can be determined based on the time period of heating failure, heating standard and heating over-standard of the district heated by each heat supply and exchange unit in the target area that does not meet the standard on the dth day, combined with the temperature change of the outdoor room temperature for n hours on the dth day, the distance from the district heated by each heat supply and exchange unit to the corresponding heat supply and exchange unit, and the aging degree of the heating pipe from the heat supply and exchange unit to the heating district. For example, in the temperature change trend graph, the distance from the district heated by each heat supply and exchange unit to the corresponding heat supply and exchange unit, the aging degree of the heating pipe and the temperature change of the outdoor room temperature at each time of the day are marked or have curves with different colors or different characteristics, so as to facilitate comprehensive analysis when diagnosing the heating status of each heat supply and exchange unit, thereby facilitating more accurate determination of the diagnosis result of the heating status of each heat supply and exchange unit.

[0078] In some embodiments, the heating status diagnosis of each heat supply and exchange unit in the target area that does not meet the standard is performed based on the temperature change trend diagram obtained from the indoor temperature at each moment within the second predetermined time period in the target area that does not meet the standard, and the heating status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard is obtained, including:

[0079] Based on the temperature change trend diagram, determine the heating status of the heating area provided by each heat supply and exchange unit in the target area that does not meet the standard; wherein the heating status of the heating area provided by each heat supply and exchange unit includes the heating of the heating area that does not meet the standard, the heating meets the standard, and the heating exceeds the standard;

[0080] Based on the proportion of the number of cells that do not meet the heating standard, the number of cells that meet the heating standard, and the number of cells that exceed the heating standard in the total number of heating cells, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is determined.

[0081] In this exemplary embodiment, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is determined based on the proportion of the number of areas that do not meet the heating standard, the number of areas that meet the heating standard, and the number of areas that exceed the heating standard in the total number of heating areas in the heating status of the heating areas provided by each heat supply and exchange unit, including:

[0082] If the number of cells that fail to meet the heating standards in the cells heated by the target heat supply and exchange unit accounts for a greater than a predetermined threshold in the total number of heating cells, or the number of cells that exceed the heating standards in the cells heated by the target heat supply and exchange unit accounts for a greater than a predetermined threshold in the total number of heating cells, it is determined that there is a problem with the heating of the target heat supply and exchange unit itself;

[0083] If the proportion of the number of cells that fail to meet the heating standards among the cells heated by the target heat supply and exchange unit is less than or equal to a predetermined threshold value, and the proportion of the number of cells that exceed the heating standards among the cells heated by the target heat supply and exchange unit is less than or equal to a predetermined threshold value, it is determined that there is a problem with the heating of the target heat supply and exchange unit for the cells that fail to meet the heating standards or the cells that exceed the heating standards.

[0084] In this exemplary embodiment, the predetermined threshold value can be set as needed. For example, 10% and so on. Under normal heating conditions, the proportion of the number of cells that do not meet the heating standard in the total number of heating cells and the proportion of the number of cells that exceed the heating standard in the total number of heating cells will be relatively small. When the proportion of the number of cells that do not meet the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is greater than the predetermined threshold, or the proportion of the number of cells that exceed the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is greater than the predetermined threshold, it can be determined that there is a problem with the heating of the target heat supply and exchange unit itself. When the proportion of the number of cells that do not meet the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is less than or equal to the predetermined threshold, and the proportion of the number of cells that exceed the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is less than or equal to the predetermined threshold, it can be determined that there is basically no problem with the heating of the target heat supply and exchange unit itself, and at this time, it can be determined that there is a problem with the heating of the target heat supply and exchange unit to the cells that do not meet the heating standard or the cells that exceed the heating standard. In this case, the heating supply can be adjusted separately for the communities where the heating supply does not meet the standard or exceeds the standard.

[0085] In some embodiments, the step of adjusting the heating state of each heat supply and exchange unit in the target area that does not meet the standard based on the heating state diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard includes:

[0086] If the diagnosis result of the heating status of each heat supply and exchange unit in the target area that does not meet the standard indicates that there is a problem with the heating of the target heat supply and exchange unit itself, the water supply temperature regulation is optimized, and the system water supply temperature setting value is adjusted according to the indoor temperature change;

[0087] If the heating status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard indicates that there is a problem with the target heat supply and exchange unit supplying heating to the community that does not meet the heating standard, the valve opening at the building unit and the user entrance is adjusted.

[0088] In this exemplary embodiment, if the heating status diagnosis results of each heat supply and exchange unit in the target area that does not meet the standard indicate that there is a problem with the heating of the target heat supply and exchange unit itself, the heat supply and exchange unit can be adjusted as a whole, such as optimizing the water supply temperature regulation and adjusting the system water supply temperature setting value according to the indoor temperature changes.

[0089] For example, the water supply temperature is too high: the water supply temperature is dynamically adjusted with the outdoor temperature, but the indoor temperature exceeds the standard rate, and the indoor temperature of each user is on the high side. At this time, the water supply temperature adjustment can be optimized, and the system water supply temperature setting value can be appropriately reduced according to the indoor temperature changes.

[0090] For example, the water supply temperature is low: the water supply temperature is dynamically adjusted with the outdoor temperature, but the indoor temperature is not up to standard at a high rate, and the indoor temperature of each user is high. At this time, the water supply temperature adjustment can be optimized, and the system water supply temperature setting value can be appropriately increased according to the indoor temperature changes.

[0091] In some embodiments, if the diagnosis result of the heating status of each heat supply and exchange unit in the target area that does not meet the standard indicates that there is a problem with the heating of the target heat supply and exchange unit itself, when optimizing the water supply temperature adjustment, the method includes:

[0092] Combined with the temperature change information corresponding to the temperature change of the outdoor room temperature for n hours on the dth day, the distance information from the community heated by each heat exchange unit to the corresponding heat exchange unit, and the aging degree information of the heating pipeline from the heat exchange unit to the heating community, determine the adjustment ratio of the valve opening at the building unit and user entrance of each heating community;

[0093] Based on the adjustment ratio of the valve openings at the building units and user entrances of each heating community, the valve openings at the building units and user entrances of each heating community are adjusted.

[0094] In this exemplary embodiment, if the heating status diagnosis results of each heat supply and exchange unit in the target area that does not meet the standard indicate that there is a problem with the heating of the target heat supply and exchange unit itself, when optimizing the water supply temperature adjustment, a comprehensive adjustment can be made based on the temperature change information corresponding to the temperature change of the outdoor room temperature for n hours on the dth day, the distance information from the residential area heated by each heat supply and exchange unit to the corresponding heat supply and exchange unit, and the aging degree information of the heating pipeline from the heat supply and exchange unit to the heating residential area.

[0095] For example, unreasonable water supply temperature control: indoor temperature changes with outdoor temperature. Under normal circumstances, when the outdoor temperature is decreasing, the water supply temperature is increasing. Conversely, when the outdoor temperature is increasing, the water supply temperature is decreasing. Otherwise, the abnormal indoor temperature is caused by unreasonable water supply temperature control of the project.

[0096] Optimization suggestions: Optimize the water supply temperature regulation of the heating system, and dynamically adjust the water supply temperature according to outdoor temperature and indoor changes.

[0097] For example, hydraulic balance is unbalanced: the indoor temperature of each user deviates greatly from the average indoor temperature of the project, and the indoor temperature of some users is significantly lower / higher than that of other users.

[0098] Optimization suggestion: Adjust the valve opening at the building unit and user entrance to achieve hydraulic balance and make the indoor temperature of each user consistent. If the user's indoor temperature is too high, it is recommended to reduce the valve opening; if the user's indoor temperature is too low, it is recommended to increase the valve opening.

[0099] For example, the adjustment ratio of the valve opening at the building unit and user entrance of each heating community is determined by combining the temperature change information corresponding to the temperature change of the outdoor room temperature for n hours on the dth day, the distance information from the community heated by each heat supply and exchange unit to the corresponding heat supply and exchange unit, and the aging degree information of the heating pipeline from the heat supply and exchange unit to the heating community, including:

[0100] Determine the distance between the heating area provided by each heat exchange unit and the corresponding heat exchange unit corresponding to the first weight, determine the aging degree of the heating pipeline from the heat exchange unit to the heating area corresponding to the second weight, and determine the temperature change corresponding to the temperature change of the outdoor room temperature for n hours on the dth day corresponding to the third weight;

[0101] The adjustment ratio of the valve opening at the building unit and user entrance of each heating community is determined by the first weight corresponding to the distance from the community heated by each heat exchange unit to the corresponding heat exchange unit, the second weight corresponding to the aging degree of the heating pipe from the heat exchange unit to the heating community, and the third weight corresponding to the temperature change corresponding to the temperature change of the outdoor room temperature for n hours on the dth day. Among them, the first weight is determined by the distance from the community heated by the heat exchange unit to the corresponding heat exchange unit, the second weight is determined by the aging degree of the heating pipe from the community heated by the heat exchange unit to the corresponding heat exchange unit, and the third weight is determined by the temperature change corresponding to the temperature change of the outdoor room temperature for n hours on the dth day.

[0102] For example, the distance from community A to the heat exchange unit is 5 km, and its corresponding first weight is 0.2; the service age of the heating pipe from the community heated by the heat exchange unit to the corresponding heat exchange unit is 20 years, and its corresponding second weight is 0.8; the temperature corresponding to the temperature change of the outdoor room temperature for n hours on the dth day is 0.2 degrees lower than yesterday, and its corresponding third weight is 0.1. If the temperature corresponding to the temperature change of the outdoor room temperature for n hours on the dth day is 0.2 degrees higher than yesterday, its corresponding third weight is -0.1. In this way, the values ​​corresponding to the first weight, the second weight and the third weight can be determined respectively, and then the first weight, the second weight and the third weight are accumulated as the adjustment ratio for adjusting the valve opening at the building unit and the user entrance of the heating community. For example, the initial valve opening at the building unit and the user entrance of the heating community is adjusted to F, and the first weight, the second weight and the third weight are accumulated to 1.1, then the initial valve opening F1 at the building unit and the user entrance of the heating community is adjusted to 1.1*F.

[0103] The adjusting the valve openings at the building units and user entrances of each heating district based on the adjustment ratios of the valve openings at the building units and user entrances of each heating district comprises:

[0104] The adjustment ratio of the valve opening at the building unit and user entrance of each heating community is multiplied by the initial valve opening at the building unit and user entrance of the heating community to adjust the valve opening at the building unit and user entrance of each heating community.

[0105] In the specific operation, the adjustment weight of the valve opening corresponding to the building unit and the user entrance can be set according to the distance between the community heated by each heat supply and exchange unit and the corresponding heat supply and exchange unit and the aging degree of the heating pipe from the heat supply and exchange unit to the heating community. In the specific operation, the adjustment weight of the valve opening corresponding to the building unit and the user entrance can be relatively large for the community heated by each heat supply and exchange unit and the corresponding heat supply and exchange unit and the heating pipe from the heat supply and exchange unit to the heating community have a relatively large valve opening, so as to improve the heating quality.

[0106] In addition to the above factors, the influence of human habits is also considered: when the temperature supply and outdoor parameters do not change significantly, the indoor temperature rises or falls significantly, and there is a trend of periodic changes. For example, users turn on the air conditioner or open the window.

[0107] Optimization suggestion: The current user's indoor temperature is not representative. Change the installation location of the indoor temperature sensor.

[0108] In this exemplary embodiment, when a problem is identified, a work order will be automatically sent to the operation and maintenance personnel for handling. For example, a work order for optimizing and adjusting the water supply temperature will be sent to guide the operation and maintenance personnel to adjust the water supply temperature setting value; a work order for adjusting the hydraulic balance will be sent to guide the operation and maintenance personnel to adjust the unadjusted user unit and the opening of the entrance valve; or a work order for changing the position of the room temperature sensor will be sent to guide the operation and maintenance personnel to change the position of the room temperature sensor, etc.

[0109] In this exemplary embodiment, when collecting room temperature data, the room temperature sensor can be connected to the Internet of Things or the cloud, and the cloud contains a room temperature processing model. The room temperature data collected in each target area is preprocessed by the room temperature processing model, and then data analysis is performed based on the room temperature data after data preprocessing, and a temperature change trend graph is drawn. Finally, the drawn temperature change trend graph can be displayed by the AI ​​model, and the temperature change trend graph can be pushed to the control unit of the distributed heating system as needed. Among them, data preprocessing includes non-heating period data elimination, abnormal data processing, etc. Among them, non-heating period status data elimination includes eliminating non-heating time data according to the start time and end time of heating.

[0110] In order to avoid the influence of abnormal data on the diagnosis results, the abnormal data needs to be eliminated. The processing rules are as follows: ① Eliminate null value data; ② Eliminate over-limit data; Among them, the normal range of supply and return water temperature difference can be: 0-50℃; the normal range of indoor temperature is 0-50℃.

[0111] In this exemplary embodiment, in addition to displaying the indoor temperature and outdoor temperature, the temperature change trend graph can also display the water supply temperature in real time. Through the hourly curves of the real-time indoor temperature, outdoor temperature, and water supply temperature, the points where the indoor temperature does not meet the standard or exceeds the standard are highlighted. Through the deep intelligent algorithm, combined with the indoor temperature, water supply temperature, and outdoor temperature data, the heating status problems of the heat exchange unit are pushed at the abnormal curve position, and the analysis suggestions described in the above embodiments corresponding to solving the problems are pushed. For example, the analysis suggestions described in the above embodiments corresponding to solving the heating problem are as follows:

[0112] 1. Unreasonable water supply temperature control: Under normal circumstances, when the outdoor temperature is decreasing, the water supply temperature is increasing. Conversely, when the outdoor temperature is increasing, the water supply temperature is decreasing. Otherwise, the abnormal indoor temperature is caused by unreasonable water supply temperature control of the project.

[0113] Recommendation: Optimize water supply temperature regulation and dynamically adjust the water supply temperature according to outdoor temperature and indoor changes.

[0114] 2. Hydraulic imbalance: the indoor temperature of each user deviates greatly from the average indoor temperature of the project;

[0115] Recommendation: Adjust the hydraulic balance so that the indoor temperature of each user room is consistent.

[0116] 3. High water supply temperature: The water supply temperature is dynamically adjusted with the outdoor temperature, but the indoor temperature exceeds the standard rate at a high rate;

[0117] Recommendation: Optimize water supply temperature regulation and appropriately lower the water supply temperature according to changes in indoor temperature.

[0118] 4. Low water supply temperature: The water supply temperature is dynamically adjusted with the outdoor temperature, but the indoor temperature is not up to standard at a high rate;

[0119] Recommendation: Optimize water supply temperature regulation and appropriately increase the water supply temperature according to changes in indoor temperature.

[0120] 5. Influence of human habits: When the water supply temperature and outdoor temperature do not change significantly, the indoor temperature rises or falls significantly, and there is a trend of periodic changes;

[0121] Recommendation: Change the installation location of the indoor temperature sensor.

[0146] Figure 2 FIG. 1 is a data processing flow chart of a distributed heating state control method according to an exemplary embodiment. Figure 2 As shown, the data processing flow in the distributed heating state control method includes:

[0147] Step 20, project configuration: configure and maintain the project's heating start time, heating end time, indoor temperature lower limit, and indoor temperature upper limit;

[0152] The present disclosure provides a distributed heating state control device, which is applied to a heating system with multiple heat exchange stations. Figure 3 FIG. 1 is a schematic diagram of a distributed heating state control device according to an exemplary embodiment. Figure 3 As shown, the distributed heating state control device includes:

[0153] The data acquisition module 30 is used to obtain the average indoor temperature of each target area within a first predetermined time period when the distributed heating system is heating, wherein each target area includes a plurality of heat supply and exchange units;

[0154] The target area heating compliance determination module 31 is used to determine the compliance of the heating of each target area based on the average indoor temperature corresponding to each target area within the first predetermined time period and the upper and lower limits of the indoor temperature;

[0155] The temperature change trend diagram determining module 32 is used to obtain a temperature change trend diagram of the indoor temperature at each moment within the second predetermined time period in the target area where the heating fails to meet the standard, if there is a target area in each target area where the heating fails to meet the standard. The temperature change trend diagram is based on the indoor temperature at each moment within the second predetermined time period in the target area where the heating fails to meet the standard. The first predetermined time period is greater than the second predetermined time period, and the temperature change trend diagram at least represents the change trend of the number of heating failure moments, heating compliance moments, and heating excess moments corresponding to the heating cells of each heat supply and exchange unit in the target area where the heating fails to meet the standard within the second predetermined time period.

[0156] A heating state diagnosis result determination module 33 is used to perform heating state diagnosis of each heat supply and exchange unit in the target area that does not meet the standard based on a temperature change trend diagram obtained from the indoor temperature at each moment within a second predetermined time period in the target area that does not meet the standard, and obtain a heating state diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard;

[0157] The heating state control module 34 is used to control the heating state of each heat supply and exchange unit in the target area that does not meet the standard based on the heating state diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard.

[0158] In this exemplary embodiment, the first predetermined time is greater than the second predetermined time. When determining the target area in each target area where the heating does not meet the standard, the average indoor temperature corresponding to each target area within the first predetermined time can be collected. The first predetermined time can be indoor temperature data for half a month, a week, or nearly two to three days. The second predetermined time can be a day within half a month or a week.

[0159] In this exemplary embodiment, when collecting indoor temperatures at each moment within the second predetermined time period in the target area that does not meet the standard, data collection can be performed at each moment within each hour within the second predetermined time period. For example, the indoor temperature from 8:01:05 to 8:02:05, the indoor temperature from 10:01:05 to 10:02:05, the indoor temperature from 12:01:05 to 12:02:05, the indoor temperature from 14:01:05 to 14:02:05, and so on, is collected in each of the 10 hours of the dth day. Then, a temperature change trend graph of the indoor temperature at each moment within the second predetermined time period in the target area that does not meet the standard is obtained through these indoor temperature collection data; wherein the temperature change trend graph at least represents the change trend of the number of heating non-standard moments, the number of heating standard moments, and the number of heating exceeding standard moments corresponding to the heating cells supplied by each heat supply and exchange unit in the target area that does not meet the standard within the second predetermined time period. Through the temperature change trend diagram of the indoor temperature, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is diagnosed, and the heating status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard is obtained; based on the heating status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is regulated, which is beneficial to improving the heating quality of the heat supply and exchange unit in the target area that does not meet the standard.

[0160] In some embodiments, the module for determining the target area heating compliance is used to

[0161] If there is a target area in each of the target areas whose corresponding average indoor temperature within the first predetermined time period is lower than the lower limit of the indoor temperature, the target area whose average indoor temperature is lower than the lower limit of the indoor temperature is determined as the target area where heating fails to meet the standard;

[0162] If there is a target area in each target area where the average indoor temperature within the first predetermined time period is higher than the upper limit of the indoor temperature, the target area where the average indoor temperature is higher than the upper limit of the indoor temperature is determined as the target area where the heating supply exceeds the standard;

[0163] If there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is between the upper and lower limits of the indoor temperature, the target area whose average indoor temperature is between the upper and lower limits of the indoor temperature is determined as the target area where heating meets the standard.

[0164] In this exemplary embodiment, when determining whether the heating of a target area meets or fails to meet or exceeds the standard, if there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is lower than the lower limit of the indoor temperature, then the target area with an average indoor temperature lower than the lower limit of the indoor temperature is determined as the target area where the heating standard does not meet; if there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is higher than the upper limit of the indoor temperature, then the target area with an average indoor temperature higher than the upper limit of the indoor temperature is determined as the target area where the heating standard exceeds; if there is a target area among the target areas whose corresponding average indoor temperature within the first predetermined time period is between the upper and lower limits of the indoor temperature, then the target area with an average indoor temperature between the upper and lower limits of the indoor temperature is determined as the target area where the heating standard meets.

[0165] In this exemplary embodiment, the upper and lower limits of the indoor temperature can be set as needed. For example, if the upper limit of the indoor temperature is 26°C and the lower limit of the indoor temperature is 18°C, then if there is a target area in each target area where the average indoor temperature is lower than the lower limit of the indoor temperature by 18°C, then the target area where the average indoor temperature is lower than the lower limit of the indoor temperature by 18°C ​​is determined as the target area where the heating fails to meet the standard; if there is a target area in each target area where the average indoor temperature is higher than the upper limit of the indoor temperature by 26°C, then the target area where the average indoor temperature is higher than the upper limit of the indoor temperature by 26°C is determined as the target area where the heating exceeds the standard; if there is a target area in each target area where the average indoor temperature is between the upper and lower limits of the indoor temperature, then the target area where the average indoor temperature is between the upper and lower limits of the indoor temperature (18°C to 26°C) is determined as the target area where the heating meets the standard, which is conducive to determining the target area where the heating fails to meet the standard.

[0166] In this exemplary embodiment, determining whether the heating of each target area meets the standard further includes:

[0167] Determine the average indoor temperature for each target area;

[0168] Based on the average indoor temperature of each target area, the heating compliance rate, heating non-compliance rate and heating excess rate of each target area are determined.

[0169] Determine the heating compliance rate for each target area, including:

[0170] is the indoor temperature failure rate of the i-th target area, n i不 is the number of hours that the indoor temperature of the i-th target area does not meet the standard, n i The total time length for temperature collection of the i-th target area;

[0171] n i达 is the total number of hours that the indoor temperature of the i-th target area meets the standard, n i is the total time length of temperature collection in the i-th target area, is the indoor temperature non-compliance rate of the i-th target area;

[0172] n i超 is the total number of hours that the indoor temperature of the i-th target area exceeds the standard, n i is the total time length of temperature collection in the i-th target area, is the indoor temperature exceeding standard rate of the i-th target area;

[0173] Among them, when obtaining the average indoor temperature of the i-th target area,

[0174] is the average indoor temperature of the i-th target area;

[0175] T ij is the average indoor temperature of the i-th target area at the j-th moment;

[0176] n i The total time length for temperature acquisition of the i-th target area.

[0177] In some embodiments, the temperature change trend diagram determination module is used to

[0178] Obtain multiple indoor average temperatures collected at multiple times within n hours on the dth day for the residential area heated by each heat supply and exchange unit in the target area that has not reached the target; wherein one time corresponds to one indoor average temperature; multiple time temperature collections are performed within each hour; d≥1, n≥2;

[0179] Based on multiple average indoor temperatures collected at multiple times on the dth day for the cells heated by each heat supply and exchange unit in the target area that did not meet the standard, and the average indoor temperature on the dth day, determine the time period when the heating did not meet the standard, the time period when the heating met the standard, and the time period when the heating exceeded the standard for the cells heated by each heat supply and exchange unit in the target area that did not meet the standard on the dth day;

[0180] Based on the time periods when the heating supply does not meet the standard, the time periods when the heating supply meets the standard and the time periods when the heating supply exceeds the standard on the d day for the cell heated by each heat exchange unit in the target area that does not meet the standard, a temperature change trend graph of the indoor temperature of the cell heated by each heat exchange unit in the target area that does not meet the standard at each moment within the second predetermined time period is obtained.

[0181] In this exemplary embodiment, when determining the heating conditions of the heat exchange units in the target area where the heating standard is not met, a plurality of indoor average temperatures collected at multiple times within n hours on the d day for the cells heated by each heat exchange unit in the target area where the standard is not met can be first obtained. Then, based on the plurality of indoor average temperatures collected at multiple times on the d day for the cells heated by each heat exchange unit in the target area where the standard is not met and the average indoor temperature on the d day, the time period during which the heating standard is not met for the cells heated by each heat exchange unit in the target area where the standard is not met and the time period during which the heating standard is not met for the cells on the d day can be determined. The time periods when the heating supply meets the standard and the time periods when the heating supply exceeds the standard, and finally, based on the time periods when the heating supply does not meet the standard, the time periods when the heating supply meets the standard and the time periods when the heating supply exceeds the standard on the d day for the community heated by each heat exchange unit in the target area that does not meet the standard, a temperature change trend graph of the indoor temperature of the community heated by each heat exchange unit in the target area that does not meet the standard at each moment within the second predetermined time period is obtained. In this way, a temperature change trend graph that can accurately reflect the heating situation of the heat exchange units in the target area that does not meet the standard can be obtained, thereby providing an effective basis for diagnosing the heating status of each heat exchange unit in the target area that does not meet the standard.

[0182] In some embodiments, the temperature change trend diagram determination module is used to

[0183] Based on the time periods during which the heating did not meet the standard, the time periods during which the heating met the standard, and the time periods during which the heating exceeded the standard on the d day for the community heated by each heat exchange unit in the target area that did not meet the standard, combined with the temperature change of the outdoor room temperature over n hours on the d day, the distance from the community heated by each heat exchange unit to the corresponding heat exchange unit, and the aging degree of the heating pipeline from the heat exchange unit to the heating community, a temperature change trend graph of the indoor temperature at each moment within the second predetermined time period for the community heated by each heat exchange unit in the target area that did not meet the standard is determined; wherein the temperature change trend graph is at least annotated with the temperature change information corresponding to the temperature change of the outdoor room temperature over n hours on the d day, the distance information from the community heated by each heat exchange unit to the corresponding heat exchange unit, and the aging degree information of the heating pipeline from the heat exchange unit to the heating community.

[0184] In this exemplary embodiment, when determining the temperature change trend graph, in order to better reflect the heating status of the heat supply and exchange unit, when determining the temperature change trend graph, the temperature change trend graph of the indoor temperature of each heat supply and exchange unit in the target area that does not meet the standard can be determined based on the time period of heating failure, heating standard and heating over-standard of the district heated by each heat supply and exchange unit in the target area that does not meet the standard on the dth day, combined with the temperature change of the outdoor room temperature for n hours on the dth day, the distance from the district heated by each heat supply and exchange unit to the corresponding heat supply and exchange unit, and the aging degree of the heating pipe from the heat supply and exchange unit to the heating district. For example, in the temperature change trend graph, the distance from the district heated by each heat supply and exchange unit to the corresponding heat supply and exchange unit, the aging degree of the heating pipe and the temperature change of the outdoor room temperature at each time of the day are marked or have curves with different colors or different characteristics, so as to facilitate comprehensive analysis when diagnosing the heating status of each heat supply and exchange unit, thereby facilitating more accurate determination of the diagnosis result of the heating status of each heat supply and exchange unit.

[0185] In some embodiments, the heating status diagnosis result determination module is used to

[0186] Based on the temperature change trend diagram, determine the heating status of the heating area provided by each heat supply and exchange unit in the target area that does not meet the standard; wherein the heating status of the heating area provided by each heat supply and exchange unit includes the heating of the heating area that does not meet the standard, the heating meets the standard, and the heating exceeds the standard;

[0187] Based on the proportion of the number of cells that do not meet the heating standard, the number of cells that meet the heating standard, and the number of cells that exceed the heating standard in the total number of heating cells, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is determined.

[0188] In this exemplary embodiment, the heating status of each heat supply and exchange unit in the target area that does not meet the standard is determined based on the proportion of the number of areas that do not meet the heating standard, the number of areas that meet the heating standard, and the number of areas that exceed the heating standard in the total number of heating areas in the heating status of the heating areas provided by each heat supply and exchange unit, including:

[0189] If the number of cells that fail to meet the heating standards in the cells heated by the target heat supply and exchange unit accounts for a greater than a predetermined threshold in the total number of heating cells, or the number of cells that exceed the heating standards in the cells heated by the target heat supply and exchange unit accounts for a greater than a predetermined threshold in the total number of heating cells, it is determined that there is a problem with the heating of the target heat supply and exchange unit itself;

[0190] If the proportion of the number of cells that fail to meet the heating standards among the cells heated by the target heat supply and exchange unit is less than or equal to a predetermined threshold value, and the proportion of the number of cells that exceed the heating standards among the cells heated by the target heat supply and exchange unit is less than or equal to a predetermined threshold value, it is determined that there is a problem with the heating of the target heat supply and exchange unit for the cells that fail to meet the heating standards or the cells that exceed the heating standards.

[0191] In this exemplary embodiment, the predetermined threshold value can be set as needed. For example, 10% and so on. Under normal heating conditions, the proportion of the number of cells that do not meet the heating standard in the total number of heating cells and the proportion of the number of cells that exceed the heating standard in the total number of heating cells will be relatively small. When the proportion of the number of cells that do not meet the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is greater than the predetermined threshold, or the proportion of the number of cells that exceed the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is greater than the predetermined threshold, it can be determined that there is a problem with the heating of the target heat supply and exchange unit itself. When the proportion of the number of cells that do not meet the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is less than or equal to the predetermined threshold, and the proportion of the number of cells that exceed the heating standard in the cells heated by the target heat supply and exchange unit in the total number of heating cells is less than or equal to the predetermined threshold, it can be determined that there is basically no problem with the heating of the target heat supply and exchange unit itself, and at this time, it can be determined that there is a problem with the heating of the target heat supply and exchange unit to the cells that do not meet the heating standard or the cells that exceed the heating standard. In this case, the heating supply can be adjusted separately for the communities where the heating supply does not meet the standard or exceeds the standard.

[0192] In some embodiments, the heating state control module is used to

[0193] If the diagnosis result of the heating status of each heat supply and exchange unit in the target area that does not meet the standard indicates that there is a problem with the heating of the target heat supply and exchange unit itself, the water supply temperature regulation is optimized, and the system water supply temperature setting value is adjusted according to the indoor temperature change;

[0194] If the heating status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard indicates that there is a problem with the target heat supply and exchange unit supplying heating to the community that does not meet the heating standard, the valve opening at the building unit and the user entrance is adjusted.

[0195] In this exemplary embodiment, if the heating status diagnosis results of each heat supply and exchange unit in the target area that does not meet the standard indicate that there is a problem with the heating of the target heat supply and exchange unit itself, the heat supply and exchange unit can be adjusted as a whole, such as optimizing the water supply temperature regulation and adjusting the system water supply temperature setting value according to the indoor temperature changes.

[0196] For example, the water supply temperature is too high: the water supply temperature is dynamically adjusted with the outdoor temperature, but the indoor temperature exceeds the standard rate, and the indoor temperature of each user is on the high side. At this time, the water supply temperature adjustment can be optimized, and the system water supply temperature setting value can be appropriately reduced according to the indoor temperature changes.

[0197] For example, the water supply temperature is low: the water supply temperature is dynamically adjusted with the outdoor temperature, but the indoor temperature is not up to standard at a high rate, and the indoor temperature of each user is high. At this time, the water supply temperature adjustment can be optimized, and the system water supply temperature setting value can be appropriately increased according to the indoor temperature changes.

[0198] In some embodiments, if the heat supply status diagnosis result of each heat supply and exchange unit in the target area that does not meet the standard indicates that there is a problem with the heat supply of the target heat supply and exchange unit itself, when optimizing the water supply temperature adjustment, the heat supply status control module is used to

[0199] Combined with the temperature change information corresponding to the temperature change of the outdoor room temperature for n hours on the dth day, the distance information from the community heated by each heat exchange unit to the corresponding heat exchange unit, and the aging degree information of the heating pipeline from the heat exchange unit to the heating community, determine the adjustment ratio of the valve opening at the building unit and user entrance of each heating community;

[0200] Based on the adjustment ratio of the valve openings at the building units and user entrances of each heating community, the valve openings at the building units and user entrances of each heating community are adjusted.

[0201] In this exemplary embodiment, if the heating status diagnosis results of each heat supply and exchange unit in the target area that does not meet the standard indicate that there is a problem with the heating of the target heat supply and exchange unit itself, when optimizing the water supply temperature adjustment, a comprehensive adjustment can be made based on the temperature change information corresponding to the temperature change of the outdoor room temperature for n hours on the dth day, the distance information from the residential area heated by each heat supply and exchange unit to the corresponding heat supply and exchange unit, and the aging degree information of the heating pipeline from the heat supply and exchange unit to the heating residential area.
