Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent regulation and control of central heating, and particularly relates to an intelligent regulation and control management system for balancing heat of secondary networks. BACKGROUND

[0002] Central heating pipe network is an indispensable part of modern urban infrastructure. It meets the heating and hot water needs of residential, commercial and industrial users by centralizing heat sources and using pipe networks to transport heat energy to users. However, in the long-term operation of the central heating system, the heat transport of the secondary pipe network cannot be intelligently adjusted for individual user terminals to meet different temperature requirements.

[0003] Chinese Patent Publication No. CN120849745A discloses a fine calculation method for balancing heat of secondary pipe networks, including the following steps: Step S1, establishing a building indoor comprehensive temperature calculation model; Step S2, establishing an outdoor comprehensive temperature calculation model, and performing time average calculation optimization; Step S3, optimizing the building indoor comprehensive temperature calculation model to eliminate system delay; Step S4, calculating the theoretical building indoor comprehensive temperature, determining whether the set target temperature of the building indoor is met, and adjusting the pipe network heat balance; Step S5, evaluating the effect of pipe network heat balance. It can be seen that the fine calculation method for balancing heat of secondary pipe networks has the following problems: it cannot accurately adjust the hot water flow state according to the room temperature and heat energy consumption of a single user terminal to accurately regulate the room temperature of the user terminal to meet the different temperature requirements of different user terminals. SUMMARY

[0004] To this end, the present application provides an intelligent regulation and control management system for balancing heat of secondary networks to overcome the problem that the prior art cannot accurately adjust the hot water flow state according to the room temperature and heat energy consumption of a single user terminal to accurately regulate the room temperature of the user terminal to meet the different temperature requirements of different user terminals.

[0005] To achieve the above-mentioned purpose, the present application provides an intelligent regulation and control management system for balancing heat of secondary networks, comprising, The detection module is configured to detect an indoor temperature value of the user end, determine an actual temperature deviation rate, determine a plurality of time periods of a single day and a preset temperature range corresponding to each time period based on a continuous actual temperature deviation rate and a preset temperature deviation rate, determine indoor temperature value eligibility based on the indoor temperature value and the preset temperature range, and determine an opening degree of the regulating valve; detect a flow rate, a water supply pressure value, and a return water pressure value of the user end to determine a first heat consumption value, determine the eligibility of heating based on a comparison result of the first heat consumption value and a preset heat consumption range and based on the indoor temperature value eligibility, and re-determine the opening degree of the regulating valve, re-determine the preset temperature range based on an unqualified heating condition in which the first heat consumption value belongs to the preset heat consumption range, and re-determine the preset heat consumption range based on an unqualified heating condition in which the first heat consumption value does not belong to the preset heat consumption range; The execution module is configured to determine the opening degree of the regulating valve, adjust the effective flow area of the water flow based on the determined adjustment amount of the opening degree, and re-determine subsequent water supply and return water pressure differences based on the water supply and return water pressure difference of the user end when the individual regulation and control of the opening degree of the regulating valve does not meet the temperature requirement of the indoor temperature of the user end. The monitoring control platform is in communication with the detection module, the heat module, and the execution module, is configured to periodically acquire and analyze data, and monitor and control the operation states of the modules, determine an indoor temperature correction rate based on continuous indoor temperature values, determine the eligibility of the balancing process, and re-determine the adjustment amount of the subsequent opening degree adjustment based on the adjustment amount of the current opening degree adjustment. The preset heat consumption range is determined based on heating characteristic parameters of a single user end, and the heating characteristic parameters include a heating area, a heating height, and a wall structure. The interval length for acquiring the parameters is related to the indoor temperature correction rate.

[0006] Further, the detection module includes a wireless indoor temperature sensor, The wireless indoor temperature sensor is configured to fixedly monitor the indoor temperature value of the user end at an interval, and transmit the indoor temperature value to the monitoring control platform for storage and waiting for acquisition. The monitoring control platform determines the actual temperature value based on the average value of a plurality of indoor temperature values acquired in a single period, determines the actual temperature deviation rate based on the first preset temperature value, and determines a plurality of time periods based on a comparison of the preset temperature deviation rate. The corresponding preset temperature range is determined based on the actual temperature value of the plurality of time periods.

[0007] Further, the monitoring control platform numbers a plurality of heat meters included in the detection module and corresponds to the addresses where the heat meters are located. When any heat meter has abnormal data exceeding a threshold value, the heat meter is located based on the number to quickly perform maintenance.

[0008] Furthermore, the monitoring and control platform, based on flow rate, supply water temperature, return water temperature, and indoor temperature values, combined with a preset heat energy consumption range, determines the type of heating failure by assessing the compliance of indoor temperature values ​​and heat energy consumption. Based on the fact that the first heat energy consumption value is within the preset heat energy consumption range, but the actual temperature value is not within the preset temperature range, the heating failure type is determined to be the first type. Based on the fact that the first heat energy consumption value does not fall within the preset heat energy consumption range, and the actual temperature value falls within the preset temperature range, the heating failure type is determined to be the second type. Based on the fact that the first heat energy consumption value does not fall within the preset heat energy consumption range and the actual temperature value does not fall within the preset temperature range, the heating failure type is determined to be the third type.

[0009] Furthermore, in response to the first type of substandard heating, the monitoring and control platform determines to increase the opening of the regulating valve and decrease the preset temperature range based on the first temperature value being less than the minimum preset temperature range value, and determines to decrease the opening of the regulating valve and decrease the preset heat consumption range based on the first temperature value being greater than the maximum preset temperature range value.

[0010] Furthermore, in response to the second type of substandard heating, the monitoring and control platform determines to reduce the opening of the regulating valve and increase the supply and return water pressure difference based on the return water temperature value being less than the return water temperature target value. Based on the return water temperature value being greater than or equal to the return water temperature target value, it determines to reduce the opening of the regulating valve and reduce the preset heat consumption range.

[0011] Furthermore, in response to the third type of unqualified heating, the monitoring and control platform determines the opening degree of the regulating valve based on the deviation direction of the actual temperature value from the preset temperature range and the deviation of the return water temperature value from the target return water temperature value. When the opening degree of the regulating valve alone does not meet the heating qualification requirements, the platform determines the preset temperature range to be adjusted based on the return water temperature value being less than the target return water temperature value, and determines the preset heat energy consumption range to be adjusted based on the return water temperature value being greater than or equal to the target return water temperature value.

[0012] Furthermore, when the opening degree of the individually controlled regulating valve does not meet the heating qualification requirements, a preset heat consumption range is determined, and a preset heat consumption range adjustment strategy is determined based on the actual temperature value and the preset temperature range.

[0013] Furthermore, it also includes a leak detection module, wherein the monitoring and control platform numbers the several temperature capsules included in the leak detection module and assigns them to their respective addresses; When any temperature capsule generates abnormal data exceeding the threshold, its location is determined by its serial number for rapid repair.

[0014] Furthermore, the interval between parameter acquisitions is related to the room temperature correction rate; the smaller the room temperature correction rate, the shorter the interval between parameter acquisitions.

[0015] Compared with the prior art, the beneficial effect of the intelligent control and management system for dual-network balanced heat in this invention is that it can accurately adjust the hot water flow state according to the room temperature and heat consumption of a single user terminal to precisely control the room temperature of the user terminal to meet the different suitable temperature requirements of different users terminal.

[0016] Furthermore, several preset temperature deviation rates with tiered values ​​are set. The actual temperature deviation rate is compared with the preset temperature deviation rate to divide several time intervals. A single period of time adjacent to consecutive and close actual temperature deviation rates is defined as a time interval. For each time interval, the actual temperature value corresponding to the median value of the corresponding actual temperature deviation rate is selected as the new first preset temperature value for that time interval. Based on several actual temperature deviation rates for each household, the user's temperature needs at different time periods are determined. Then, based on the user's temperature needs, different first preset temperature values ​​are set for different time periods to fully and intelligently regulate the indoor temperature according to each household's indoor temperature needs, thereby optimizing resources and making each household more satisfied with the heating situation.

[0017] Furthermore, a preset temperature range is set for the heating characteristic parameters of a single user, and the room temperature is detected and compared to determine whether the room temperature is qualified, thereby adjusting the hot water flow rate to ensure the indoor temperature.

[0018] Furthermore, it can detect the soil temperature around the secondary pipeline network during transportation, and monitor whether there is a leak in the secondary pipeline network by setting a preset temperature threshold. In case of abnormal data, it can quickly locate and repair the leak, reducing the waste of resources. Attached Figure Description

[0024] Please see Figure 1 As shown, a detailed embodiment of the intelligent control and management system for regulating the thermal balance of the secondary power grid is described: A smart control and management system for balanced thermal power in a two-network system includes, The detection module is used to detect the indoor temperature value at the user end, determine the actual temperature deviation rate, and determine several time periods of the day and the corresponding preset temperature range based on the continuous actual temperature deviation rate and the preset temperature deviation rate. Based on the indoor temperature value and the preset temperature range, it determines the qualification of the indoor temperature value to determine the opening of the regulating valve. It is also used to detect the flow rate, supply water pressure value and return water pressure value through the user end to determine the first heat energy consumption value. Based on the comparison result of the first heat energy consumption value and the preset heat energy consumption range, and based on the qualification of the indoor temperature value, it determines the qualification of the heating to redetermine the opening of the regulating valve. Based on the unqualified heating situation where the first heat energy consumption value is within the preset heat energy consumption range, it redetermines the preset temperature range. Based on the unqualified heating situation where the first heat energy consumption value is not within the preset heat energy consumption range, it redetermines the preset heat energy consumption range. The heating module is connected to the user end and supplies the hot water supplied by the heat source module to the user end after regulation. The execution module, in response to determining the opening degree of the regulating valve to adjust the effective flow area of ​​the water flow according to the determined adjustment amount, and when the temperature requirement of the user's room temperature is not met by individually adjusting the opening degree of the regulating valve, re-determines the subsequent supply and return water pressure difference based on the supply and return water pressure difference at the user's end. The monitoring and control platform, connected to the detection module, thermal module, and execution module, is used for periodic data acquisition and analysis, as well as monitoring and regulating the operating status of each module. Based on continuous indoor temperature values, it determines the room temperature correction rate, judges the qualification of the balancing process, and redetermines the adjustment amount for subsequent opening adjustments based on the current opening adjustment amount. The preset heat energy consumption range is determined according to the heating characteristic parameters of a single user terminal, including heating area, heating height, and wall structure. The interval between parameter acquisitions is related to the room temperature correction rate.

[0025] refer to Figure 2 The process of regulating the thermal balance of the secondary network is explained in detail: The preset heat consumption range is set according to the heating characteristic parameters of a single user terminal; Periodically acquire indoor temperature, flow rate, supply water temperature and return water temperature of a single user terminal; The actual temperature deviation rate is determined based on the indoor temperature value, the indoor temperature compliance level is determined based on the actual temperature deviation rate, and several time periods of a single day and the preset temperature range corresponding to each time period are determined based on the continuous indoor temperature compliance level. Based on the indoor temperature value and the preset temperature range, the indoor temperature value is deemed qualified, and the adjustment method of the regulating valve opening is determined based on the qualified indoor temperature value. The first heat energy consumption value is determined based on the flow rate, supply water temperature and return water temperature. The first heat energy consumption value is compared with the preset heat energy consumption range to determine the qualification of the first heat energy consumption value. The qualification of the first heat energy consumption value is combined to determine the qualification of the heating, so as to redetermine the opening of the regulating valve, or redetermine the preset temperature range, or redetermine the preset heat energy consumption range. In response to the fact that the opening of the regulating valve alone does not meet the temperature requirements of the user's room temperature, the supply and return water pressure difference value is re-determined based on the current supply and return water pressure difference value. Based on continuous indoor temperature values, determine the room temperature correction rate, judge the qualification of the balancing process, and combine the current opening adjustment amount to determine the adjustment amount for the next opening adjustment. Among them, heating characteristic parameters include heating area, heating height and wall structure, and the interval for periodically acquiring parameters is related to the room temperature correction rate.

[0026] The wireless room temperature sensor monitors the indoor temperature in real time and obtains the indoor temperature value. It compares the indoor temperature with the preset indoor temperature value to determine the qualification of temperature control. The monitoring and control platform periodically obtains the indoor temperature value of the wireless room temperature sensor, compares the indoor temperature value with the preset temperature range, and determines the qualification of room temperature. Set a first preset temperature value and a corresponding first temperature offset to determine the preset temperature range; The first preset temperature value is 22℃, and the first temperature offset is 2℃. The first temperature offset can also be set to different values ​​according to different accuracy requirements, such as 0.5℃, 1℃, 1.5℃, or 2.5℃. The indoor temperature value can also be set to different values ​​according to different requirements, such as 21℃, 23℃, or 24℃. The indoor temperature value is recorded once per minute. The average value of several indoor temperature values ​​within a single period is the actual temperature value. First preset temperature value ± first temperature offset = preset temperature range. The first temperature offset can be taken in different values ​​according to the heating requirements of different regions. The first preset temperature value can be determined based on the midpoint between the minimum and maximum heating temperatures required in the region, or it can be determined based on a temperature value within the range of suitable indoor human body temperature under big data. If the actual temperature value is less than or equal to the preset temperature range, the temperature control is deemed to be qualified; if the actual temperature value is less than or equal to the preset temperature range, the temperature control is deemed to be unqualified. Based on the unqualified temperature control, the opening degree of the regulating valve is determined. Then, the opening degree of the regulating valve is adjusted according to the temperature-flow curve. At this time, the supply and return water pressure difference is not adjusted according to the fixed preset supply and return water pressure difference value, that is, the hydrodynamic force is the same and the water flow velocity is the same. The temperature-flow rate curve is a statistical curve representing the corresponding indoor temperature under different flow rates of hot water supplied to the household, based on big data statistics. The actual temperature value is determined by the average value of the real-time temperature values ​​within the period interval. The actual temperature deviation rate is determined based on the actual temperature value. The actual temperature deviation rate is determined by dividing the difference between the actual temperature value and the first preset temperature value by the first preset temperature value. The actual temperature deviation rate is compared with the preset temperature deviation rate to determine its qualification level. Several preset temperature deviation rates with tiered values ​​are set. The actual temperature deviation rate is compared with the preset temperature deviation rate to divide several time intervals. The single-cycle time intervals adjacent to consecutive and close actual temperature deviation rates are defined as a time period. For each time interval, the actual temperature value corresponding to the median value of the corresponding actual temperature deviation rate is selected as the new first preset temperature value for that time interval. Based on several actual temperature deviation rates for each household, the user's temperature needs at different time periods are determined. Then, based on the user's temperature needs, different first preset temperature values ​​are set for different time periods to fully and intelligently regulate the indoor temperature according to each household's indoor temperature needs, thereby optimizing resources and making each household more satisfied with the heating situation.

[0027] The heat meter measures the user's heat energy consumption, collects flow rate, supply water temperature and return water temperature in real time, calculates heat energy consumption based on flow rate, supply water temperature and return water temperature, and the monitoring and control platform periodically obtains the first heat energy consumption value of the heat meter, compares it with the preset heat energy consumption range, and combines it with the indoor temperature value to determine the qualification of heating. The preset heat energy consumption range is determined by calculation based on heating characteristic parameters, a first preset temperature value, a preset opening degree, and a preset flow rate. Based on the heating characteristic parameters, a first heat energy consumption value is preset. The preset heat energy consumption range is determined by the preset first heat energy consumption value ± heat energy deviation value. If the first heat energy consumption value ≠ the preset heat energy consumption range and the indoor temperature value ≠ the preset temperature range, the heating is deemed qualified. If the first heat energy consumption value ≠ the preset heat energy consumption range and the indoor temperature value ≠ the preset temperature range, the heating is deemed unqualified. refer to Figure 3 The process for determining the types of heating system deficiencies is detailed below: Furthermore, the monitoring and control platform, based on flow rate, supply water temperature, return water temperature, and indoor temperature values, combined with a preset heat energy consumption range, determines the type of heating failure by assessing the compliance of indoor temperature values ​​and heat energy consumption. Based on the fact that the first heat energy consumption value is within the preset heat energy consumption range, but the actual temperature value is not within the preset temperature range, the heating failure type is determined to be the first type. Based on the fact that the first heat energy consumption value does not fall within the preset heat energy consumption range, and the actual temperature value falls within the preset temperature range, the heating failure type is determined to be the second type. Based on the fact that the first heat energy consumption value does not fall within the preset heat energy consumption range and the actual temperature value does not fall within the preset temperature range, the heating failure type is determined to be the third type.

[0028] Specifically, the monitoring and control platform assigns a number to each of the heat meters included in the detection module and associates them with their respective addresses. When any heat meter generates abnormal data exceeding a threshold, its location is determined by its serial number, enabling rapid repair.

[0029] Furthermore, specifically, in response to the first type of substandard heating, the monitoring and control platform determines to increase the opening of the regulating valve and decrease the preset temperature range based on the first temperature value being less than the minimum preset temperature range; and determines to decrease the opening of the regulating valve and decrease the preset heat consumption range based on the first temperature value being greater than the maximum preset temperature range. In response to the first type of substandard heating, the monitoring and control platform determines the adjustment method according to the direction of deviation of the indoor temperature value, wherein... If the indoor temperature is less than the minimum value of the preset temperature range, determine to increase the opening of the regulating valve and decrease the preset temperature range; If the indoor temperature is greater than the maximum value of the preset temperature range, the opening of the regulating valve will be reduced and the preset heat consumption range will be reduced.

[0030] If the indoor temperature is lower than the minimum value of the preset temperature range, the heating is not up to standard. Scenario 1: The preset temperature range is not within the user's comfort range. The user adjusts the indoor temperature to lower it, resulting in wasted resources. Confirm that the first preset temperature value and the opening of the regulating valve are adjusted for the user to bring the preset temperature range into the user's comfort range. At the same time, reduce the flow supplied to the user to save resources and avoid waste. Scenario 2: Poor insulation of the house leads to wasted heat energy, causing the indoor temperature to fall below the preset temperature range. In this case, the preset heat energy consumption range and the opening of the regulating valve should be adjusted to ensure that the flow rate is increased for the user and to meet the user's indoor temperature requirements.

[0031] Furthermore, specifically, in response to the second type of substandard heating, the monitoring and control platform determines to decrease the opening of the regulating valve and increase the supply-return pressure difference based on the return water temperature being lower than the target return water temperature value; and determines to decrease the opening of the regulating valve and reduce the preset heat consumption range based on the return water temperature being greater than or equal to the target return water temperature value. In response to the second type of substandard heating, the monitoring and control platform determines the adjustment method based on the deviation of the return water temperature value, wherein... If the return water temperature is lower than the target return water temperature, determine that the opening of the regulating valve should be reduced and the pressure difference between the supply and return water should be increased. If the return water temperature is greater than or equal to the target return water temperature, the opening of the regulating valve will be reduced and the preset heat consumption range will be reduced.

[0032] If the first heat energy consumption value is less than the preset heat energy consumption range and the indoor temperature value is less than the preset temperature range, then the heating is deemed unqualified. The return water temperature value is compared with the return water temperature target value to determine the reason for the unqualified heating. If the return water temperature is lower than the target return water temperature, the heating is deemed unqualified. The first heat energy consumption value exceeds the preset heat energy consumption range. The user adjusts the indoor temperature to make the heating qualified. For example, the indoor hot water circulation path is lengthened, so that the hot water stays for a longer time. The return water temperature is lower than the target return water temperature. Therefore, based on the user's indoor temperature, it can be determined not to adjust the opening of the regulating valve. At this time, the room temperature consistency method can be used to determine that the heating is qualified. If this method is used, it needs to be marked for individual control. If this method is not followed, the supply and return water pressure difference needs to be adjusted to eliminate the influence of the long hot water circulation path at the user's end. At the same time, the opening is reduced to increase the supply and return water pressure difference to raise the room temperature while reducing the adjustment of the room temperature, ensuring that the room temperature after adjustment is still within the indoor temperature value ≠ the preset temperature range. If the return water temperature is greater than or equal to the target return water temperature, the heating is deemed unqualified. If the user tries to maintain the indoor temperature within the preset range by opening windows or other means to dissipate heat, it indicates that the user's preset heat consumption range is incorrectly set, being too high. Therefore, the preset heat consumption range needs to be reset. Simultaneously, the opening of the regulating valve should be reduced. Specifically, in response to the third type of unqualified heating, the monitoring and control platform determines the opening of the regulating valve based on the deviation direction of the actual temperature value from the preset temperature range and the deviation of the return water temperature value from the return water temperature target value. When the opening of the regulating valve alone does not meet the heating qualification requirements, the platform determines the preset temperature range to be adjusted based on the return water temperature value being less than the return water temperature target value, and determines the preset heat energy consumption range to be adjusted based on the return water temperature value being greater than or equal to the return water temperature target value. The monitoring and control platform responds to the third type of substandard heating by determining the adjustment method based on the direction of deviation of the indoor temperature value and the deviation of the return water temperature value. If the return water temperature value is greater than or equal to the target return water temperature value, and the actual temperature value is less than the minimum value of the preset temperature range, it is determined that the opening of the regulating valve should be increased. Based on the adjusted opening, it is determined whether to adjust the preset heat energy consumption range. If the return water temperature is less than the target return water temperature and the actual temperature is less than the minimum value of the preset temperature range, then the opening of the control valve and the preset temperature range will be reduced. If the return water temperature value is greater than or equal to the target return water temperature value, and the actual temperature value is greater than the maximum value of the preset temperature range, then the opening of the control valve is reduced and the preset heat energy consumption range is reduced. If the return water temperature is less than the target return water temperature, and the actual temperature is greater than the maximum value of the preset temperature range, then the opening of the regulating valve and the preset temperature range will be reduced.

[0033] If the first heat energy consumption value is less than or equal to the preset heat energy consumption range, and the actual temperature value is less than or equal to the preset temperature range, then the heating is deemed unqualified. The return water temperature value is compared with the return water temperature target value to determine the heating qualification. If the return water temperature value is greater than or equal to the return water temperature target value, and the indoor temperature value is less than the minimum value of the preset temperature range, then the heating is deemed unqualified. It is confirmed that the opening of the regulating valve is increased to ensure that the first heat energy consumption value is increased to meet the preset heat energy consumption range, while the indoor temperature value is increased. The opening of the regulating valve is re-determined based on whether it meets the preset temperature range, and based on the determined opening of the regulating valve, it is determined whether to adjust the preset heat energy consumption range. If the return water temperature is less than the target return water temperature, and the actual temperature is less than the minimum value of the preset temperature range, the heating is deemed unqualified. It is confirmed that the preset temperature range is not within the user's comfort range. The indoor temperature required by the user is determined by adjusting the preset temperature range, and then the opening degree of the regulating valve is determined; as well as the corresponding preset heat energy consumption range is determined. If the return water temperature value is greater than or equal to the target return water temperature value, and the actual temperature value is greater than the maximum value of the preset temperature range, then the heating is deemed unqualified. It is confirmed that the preset heat energy consumption range is set too high. At this time, the opening of the regulating valve is too large. The preset heat energy consumption range and the opening of the regulating valve should be re-determined based on the current first heat energy consumption value and the indoor temperature value. While reducing the heat input of the user, the indoor temperature should also be reduced to avoid waste of resources. If the return water temperature is less than the target return water temperature, and the actual temperature is greater than the maximum value of the preset temperature range, the heating is deemed unqualified. If it is confirmed that the user has reduced the indoor temperature by increasing heat dissipation, and the indoor temperature still exceeds the preset temperature range, the opening of the regulating valve is reduced, and the range is redefined based on the current preset heat energy consumption range.

[0034] refer to Figure 4 The process of determining whether to adjust the preset heat consumption range is explained in detail: Specifically, the determination of whether to adjust the preset heat consumption range based on the adjusted opening degree, wherein... If the actual temperature value is less than or equal to the preset temperature range, and the first heat energy consumption value is less than or equal to the preset heat energy consumption range, then it is determined that the preset heat energy consumption range will not be adjusted. If the actual temperature value is less than or equal to the preset temperature range, and the first heat energy consumption value is less than or equal to the preset heat energy consumption range, then the preset heat energy consumption range will be adjusted.

[0035] A pressure sensor detects the supply and return water pressure values ​​at the user end. When adjusting the opening of the regulating valve alone is insufficient to regulate the indoor temperature, the system adjusts both the supply and return water pressure values, regulating the pressure difference between the supply and return water, thereby regulating the flow rate of hot water and further regulating the indoor temperature. If the regulating valve opening reaches its maximum value and is still insufficient to achieve an indoor temperature within the preset heat consumption range, the user end supply water pressure is increased to ensure sufficient water flow, allowing hot water to quickly circulate through the user end pipes, thus increasing the temperature of the heating water and ensuring the indoor temperature remains within the preset heat consumption range, indicating that the heating is adequate. Conversely, if the regulating valve opening reaches its minimum value and is still insufficient to achieve the preset heat consumption range, the user end supply water pressure is decreased to reduce water flow, preventing the rapid flow of hot water through the user end pipes and avoiding excessively high indoor temperatures, thus lowering the temperature of the heating water and ensuring the indoor temperature remains within the preset heat consumption range, indicating that the heating is adequate.

[0036] Specifically, it also includes a leak detection module. The monitoring and control platform numbers the several temperature capsules included in the leak detection module and assigns them to their respective addresses. By collecting the temperature data of each temperature capsule in real time and analyzing its changing trend, it determines whether there is a leak or abnormal heat dissipation in the heating pipeline. When the temperature difference between adjacent capsules exceeds a set threshold or the temperature drops suddenly, the system automatically marks the abnormal area and issues an alarm. Combined with the pressure sensor data, it performs linkage analysis to confirm the possibility of leakage, so as to quickly respond and carry out maintenance to avoid heat loss and resource waste.

[0037] When any temperature capsule generates abnormal data exceeding the threshold, its location is determined by its serial number for rapid repair.

[0038] Specifically, the periodic acquisition interval is related to the room temperature correction rate; the smaller the room temperature correction rate, the shorter the periodic acquisition interval. When the room temperature correction rate approaches zero, the system automatically shortens the data acquisition cycle to the minimum threshold to ensure real-time capture and precise control of temperature changes. If the room temperature correction rate does not change significantly within three consecutive cycles, the acquisition interval is gradually extended to reduce the system's computational load. By dynamically adjusting the acquisition frequency, energy efficiency is optimized while ensuring stable indoor temperature, achieving intelligent and refined control of the heating system.

[0039] Specifically, the process for detecting leaks in the secondary pipeline network will be explained in detail: The leak detection module is used to detect the working status of the secondary pipeline network. The module includes temperature capsules, which are installed around the secondary pipeline network according to a preset installation procedure to measure the network temperature. By numbering several temperature capsules, it enables timely detection of pipeline leaks, accurate location of leak points, and prompt repair. It provides long-term monitoring of temperature changes at leak-prone points, accurately collects temperature data changes around the heating pipeline, and performs real-time monitoring and timely alarms during the heating season, detecting early leaks in the pipeline network as early as possible. This is particularly suitable for areas where manual inspection is difficult, such as long-distance pipelines, avoiding disruption to heating for users and preventing the waste of resources and funds due to long repair times.

[0040] The preset installation procedure is as follows: drill a hole within 50 cm of the secondary pipeline network and bury a temperature capsule.
