Abstract
Description
Technical Field
[0001] This application relates to the technical field of centralized heating, and in particular to a method, system, equipment and storage medium for regulating the heat balance of a heating network. Background Technology
[0002] In northern my country, centralized heating is commonly used to cope with the cold winter climate. Therefore, heating stations are usually set up near residential or industrial areas. After the secondary water supply is heated by the heat exchanger, the hot water is distributed to different rooms in each heating area through the various outlets on the distributor. Then, the water is collected in the collector through the various inlets, and the collector returns this water to the heat exchanger for reheating, thus creating a cycle.
[0003] Because the distance between the heating station and each heating area varies, the time it takes for hot water to flow into the heating areas differs, leading to uneven heat distribution and a poor user experience. To ensure balanced heating across all areas, the flow rate needs to be regulated. Currently, this is mainly done through electric regulating valves. However, this method has drawbacks. Electric regulating valves have a large adjustment range and are frequently adjusted due to temperature or load changes. This large adjustment range can cause significant fluctuations in the temperature and pressure of the heating system, potentially leading to safety accidents. Summary of the Invention
[0004] To reduce the possibility of safety accidents caused by electric regulating valves, this application provides a method, system, equipment, and storage medium for regulating the heat balance of a thermal pipeline network.
[0005] In a first aspect of this application, a method for regulating the heat balance of a thermal pipeline network is provided. The method includes: The system obtains the actual temperature, corrected temperature, and cycle time of the heating area. The actual temperature reflects the temperature of the heating area, the corrected temperature reflects the temperature demand of the heating area, and the cycle time represents the time it takes for hot water to flow from the heating station into the heating area and back to the heating station. The adjustment range is determined based on the actual temperature and the corrected temperature. The adjustment range is used to reflect the change in valve opening of the electric control valve during the process of changing from the actual temperature to the corrected temperature. The electric regulating valve is adjusted according to the adjustment range and cycle time to achieve heating in the heating area.
[0006] As can be seen from the above technical solutions, by obtaining the actual temperature and corrected temperature of the heating area, the adjustment needs of the heating area are determined. Then, the adjustment range of the electric regulating valve is determined according to the adjustment needs of the heating area. The electric regulating valve is gradually adjusted according to the adjustment range and cycle time. While meeting the heating needs of the heating area, the aimless and irregular large-scale adjustment of the electric regulating valve is avoided, thereby reducing the possibility of safety accidents caused by the electric regulating valve.
[0007] In one possible implementation, the adjustment range of the electric regulating valve corresponding to the heating area is determined based on the actual temperature and the corrected temperature, including: Obtain the ambient temperature of the heating area; the ambient temperature represents the outdoor temperature of the heating area. Determine the temperature amplitude relationship curve corresponding to the ambient temperature. The temperature amplitude relationship curve is used to reflect the correspondence between the actual temperature and / or the corrected temperature and the adjustment amplitude. The adjustment range is determined based on the amplitude values corresponding to the actual temperature and the corrected temperature on the temperature amplitude relationship curve.
[0008] In one possible implementation, the adjustment range is determined based on the amplitude values corresponding to the actual temperature and the corrected temperature on the temperature amplitude relationship curve, including: When the amplitude value corresponding to the actual temperature is the same as the current amplitude value, the amplitude difference corresponding to the corrected temperature is recorded as the adjustment amplitude. When the amplitude value corresponding to the actual temperature is different from the current amplitude value, the adjustment amplitude is calculated based on the temperature difference ratio. The temperature difference ratio is the ratio of the temperature difference to the actual temperature, and the temperature difference is the difference between the actual temperature and the corrected temperature.
[0009] In one possible implementation, the adjustment range is the product of the temperature difference ratio and the actual temperature.
[0010] In one possible implementation, adjusting the electrically operated regulating valve according to the adjustment amplitude and the cycle time includes: Determine whether the adjustment range is greater than the adjustment threshold; If so, adjust the electric regulating valve multiple times according to the adjustment threshold; After each adjustment of the electric regulating valve, the latest temperature is obtained. The latest temperature represents the temperature of the heating area obtained after a cycle time following the adjustment of the electric regulating valve. When the latest temperature reaches the corrected temperature, stop adjusting the electric regulating valve.
[0011] In one possible implementation, the method also includes: If so, adjust the electric regulating valve according to the adjustment range.
[0012] In one possible implementation, the method also includes: Adjust the electric regulating valve according to the preset adjustment threshold; After each adjustment of the electric regulating valve, the latest temperature is obtained. The latest temperature represents the temperature of the heating area obtained after a cycle time following the adjustment of the electric regulating valve. When the latest temperature reaches the corrected temperature, stop adjusting the electric regulating valve.
[0013] In a second aspect of this application, a thermal balance regulation system for a heating network is provided. The system includes: The data acquisition module is used to acquire the actual temperature, corrected temperature and cycle time of the heating area. The actual temperature represents the temperature of the heating area, the corrected temperature is used to reflect the temperature demand of the heating area, and the cycle time represents the time it takes for hot water to flow from the heating station into the heating area and back to the heating station. The amplitude determination module is used to determine the adjustment amplitude based on the actual temperature and the corrected temperature. The adjustment amplitude is used to reflect the change in valve opening of the electric control valve during the change from the actual temperature to the corrected temperature. The valve adjustment module is used to adjust the electric regulating valve according to the adjustment range and cycle time to achieve heating in the heating area.
[0014] In a third aspect of this application, an electronic device is provided. The electronic device includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described above.
[0015] In a fourth aspect of this application, a computer-readable storage medium is provided having a computer program stored thereon that, when executed by a processor, implements the method according to the first aspect of this application.
[0016] In summary, this application includes at least one beneficial technical effect: By obtaining the actual temperature and corrected temperature of the heating area, the regulation requirements of the heating area are determined. Then, the adjustment range of the electric regulating valve is determined according to the regulation requirements of the heating area. The electric regulating valve is gradually adjusted according to the adjustment range and cycle time. While meeting the heating requirements of the heating area, the aimless and irregular large-scale adjustment of the electric regulating valve is avoided, thereby reducing the possibility of safety accidents caused by the electric regulating valve.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.
[0026] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.
[0027] Figure 1 This is a schematic diagram of an example operating environment for an embodiment of this application. The operating environment includes a primary water supply main pipe 1, a primary return water main pipe 2, a heat exchanger 3, a secondary water supply main pipe 4, a secondary return water main pipe 5, a water distributor 6, and a water collector 7. The primary side inlet of the heat exchanger 3 is connected to the primary water supply main pipe 1, and the primary side outlet of the heat exchanger 3 is connected to the primary return water main pipe 2. An electric three-way valve 8 is installed on the primary water supply main pipe 1. A bypass pipe 9 is installed between the primary water supply and return pipes through the electric three-way valve 8. Adjusting the opening of the three-way valve can control the flow rate of heat exchange entering the heat exchanger 3 to achieve energy saving and consumption reduction. The secondary outlet of the heat exchanger 3 enters the distributor 6 through the secondary water supply main pipe 4. The distributor 6 is connected to four water supply branch pipes 14, each of which is connected to a heating area. The water then flows through four return water branch pipes 16 and collects at various collection points into the collector 7. This water is then returned to the heat exchanger 3 for reheating by the secondary circulation pump 20, and the cycle continues. A secondary water supply main pipe temperature sensor 10 and a secondary return water main pipe temperature sensor 11 are installed on the secondary water supply main pipe 4 and the secondary return water main pipe 5, respectively. Each of the four water supply branch pipes 14 of the distributor 6 is equipped with a water supply branch pipe butterfly valve 12, a flow meter 13, and a branch pipe water supply temperature sensor 15. The return water branch pipes 16 of the collector 7 are equipped with a return water branch pipe butterfly valve 17, a branch pipe return water temperature sensor 19, and a branch pipe return water electric regulating valve 18 for flow regulation. Each heating area is connected to the heating building through at least two water supply branch pipes 14. Each water supply branch pipe 14 is equipped with a building electric regulating valve 21. The indoor temperature collection device 22 is installed in the user's room in the heating building.
[0028] The aforementioned operating environment also includes a control cabinet 23, which houses a power module 27, a data acquisition module 24, a controller 25, and a switch 26. The cabinet door of the control cabinet 23 is equipped with an intelligent window 28, a handheld device 29, indicator lights 30, and an alarm 31. The power module 27 supplies power to the data acquisition module 24, controller 25, switch 26, intelligent window 28, handheld device 29, indicator lights 30, electric regulating valve, and flow meter 13. The data acquisition module 24 is connected to the signal output terminals of the primary water supply electric three-way valve 8, the secondary water supply main pipe temperature sensor 10, the secondary return water main pipe temperature sensor 11, the flow meter 13, the branch pipe water supply temperature sensor 15, the branch pipe return water temperature sensor 19, the branch pipe return water electric regulating valve 18, the building electric regulating valve 21, and the room temperature acquisition device 22. The data acquisition module 24 acquires various signals and sends them to the controller 25. The controller 25 is connected to the smart window 28 via the switch 26. The controller 25 is used to automatically adjust the flow rate of the branch pipes in each heating zone.
[0029] The indicator light 30 is used for system power indication; it illuminates when the power supply module 27 is low. The alarm 31 is used to sound an alarm when the system malfunctions. The handheld controller 29 is used to directly control the electric regulating valve via the control cabinet 23. It can switch between remote and local valve control states, switch between manual and automatic valve control modes, and manually set the valve opening value. It can operate when the intelligent window 28 or the duty room monitoring platform 32 malfunctions, and also during inspection and maintenance. The intelligent window 28 is used for human-machine interaction. The human-machine interface includes a zoned flow self-balancing control interface and an electric regulating valve periodic delay progressive control interface, as shown in the reference... Figure 2 and Figure 3 .
[0030] To facilitate real-time monitoring by on-duty personnel, the output port of the aforementioned data acquisition module 24 can transmit the acquired signal to the duty room monitoring platform 32. The duty room monitoring platform 32 is also equipped with interfaces for zoned flow self-balancing control, electric regulating valve period delay progressive control, and abnormal alarms.
[0031] This application provides a method for regulating the heat balance of a thermal pipeline network. The main process of the method is described below.
[0032] like Figure 4 As shown: Step S101: Obtain the actual temperature, corrected temperature, and cycle time of the heating area.
[0033] Specifically, the aforementioned actual temperature reflects the temperature of the aforementioned heating area. The aforementioned corrected temperature reflects the temperature demand of the aforementioned heating area. The aforementioned cycle time represents the time it takes for hot water to flow from the heating station into the heating area and back to the heating station. In a specific example, the aforementioned actual temperature can be the average indoor temperature of all users in the aforementioned heating area, the indoor temperature of a single user in the heating area, or the average indoor temperature of some users in the heating area. In other embodiments, the aforementioned actual temperature can be determined according to the actual situation, and is not limited here. The aforementioned corrected temperature refers to the temperature demand of some or all users in the heating area. For example, if a user's indoor temperature is 15℃, i.e., the actual temperature is 15℃, but the user wants to achieve an indoor temperature of 20℃, then the corrected temperature is 20℃. As another example, if three users in the heating area want to achieve 19℃, 20℃, and 21℃ respectively, the corrected temperature can be obtained by averaging the three temperatures. The corrected temperature can be obtained through the maximum value, minimum value, median, or mode, etc., and is not limited here.
[0034] Reference Figure 1 It can be understood that the distance between each heating area and the heating station is different, so the time it takes for hot water to return to the heating station after passing through the main water supply pipe, the branch water supply pipe 14, the return water branch pipe 16, and the main water return pipe is also different. The time it takes for the hot water to flow out of the heating station and finally return to the heating station is the cycle time, and the cycle time of each heating area will vary to a large or small extent.
[0035] Step S102: Determine the adjustment range based on the actual temperature and the corrected temperature.
[0036] Specifically, the aforementioned adjustment range is used to reflect the change in valve opening of the electric regulating valve during the change from the actual temperature to the corrected temperature. In a specific example, the electric regulating valve refers to the butterfly valve 12 of the water supply branch pipe 14 in the aforementioned operating environment. In other embodiments, it can be other electric regulating valves that affect the temperature change of the heating area, and is not limited here. For example, the opening range of the electric regulating valve is set to 0%-100%. If it is necessary to adjust the valve opening of the electric regulating valve from 50% to 70%, the adjustment range is 20%.
[0037] Further, the ambient temperature of the heating area is obtained, whereby the ambient temperature represents the outdoor temperature of the heating area; a temperature amplitude relationship curve corresponding to the ambient temperature is determined, whereby the temperature amplitude relationship curve reflects the correspondence between the actual temperature and / or the corrected temperature and the adjustment amplitude; and the adjustment amplitude is determined based on the amplitude values corresponding to the actual temperature and the corrected temperature on the temperature amplitude relationship curve.
[0038] It's understandable that heating stations raise the temperature of a heating area by flowing hot water into it. However, the temperature of the heating area will vary under different weather conditions, even with the same amount of hot water flowing in. For example, when the ambient temperature is 5℃ and the electric regulating valve is open 50%, the temperature of the heating area can reach 15℃. But when the ambient temperature is 0℃, the temperature of the heating area will only reach 8℃ with the electric regulating valve open 50%. Therefore, the relationship between the valve opening of the electric regulating valve and the temperature of the heating area will change when the ambient temperature is different.
[0039] The above temperature amplitude relationship curve was obtained in the following way: Under a given ambient temperature, the actual temperature corresponding to different valve opening degrees is obtained. For example, when the valve opening is 0%, the actual temperature equals the ambient temperature of 0°C. The actual temperatures corresponding to valve opening degrees of 25%, 50%, 75%, and 100% are obtained sequentially. Data fitting of these five sets of data yields a temperature amplitude relationship curve. In other embodiments, more sets of data can be obtained to improve the accuracy of the temperature amplitude relationship curve. Alternatively, historical data from the heating area can be used, and machine learning, neural networks, or other methods can be employed to obtain the correspondence between the valve opening degree of the electric regulating valve and the temperature of the heating area—that is, the temperature amplitude relationship curve.
[0040] Furthermore, when the amplitude value corresponding to the actual temperature is the same as the current amplitude value, it indicates that the temperature amplitude relationship curve is very accurate, and the amplitude difference corresponding to the corrected temperature is recorded as the adjustment amplitude. For example, in the temperature amplitude relationship curve, the valve opening corresponding to 15℃ is 60%, and the valve opening corresponding to 20℃ is 80%. Given that the actual temperature is 15℃, the amplitude value corresponding to 15℃ is 60%, and the current amplitude value refers to the actual valve opening in the heating station, which is 60%, the temperature amplitude relationship curve is considered very accurate. Therefore, the amplitude difference corresponding to the corrected temperature of 20℃ is 80% - 60% = 20%.
[0041] When the amplitude value corresponding to the actual temperature differs from the current amplitude value, the adjustment range is calculated based on the temperature difference ratio. This ratio is the ratio of the temperature difference to the actual temperature, and the temperature difference is the difference between the actual temperature and the corrected temperature. For example, in the temperature amplitude curve, 15℃ corresponds to a valve opening of 60%, and 20℃ corresponds to a valve opening of 80%. Given an actual temperature of 15℃ and an amplitude value of 60%, and the current amplitude value (50%), which refers to the actual valve opening in the heating station, we assume there is some error in the temperature amplitude curve because 50% and 60% are not equal. Therefore, we need to calculate the temperature difference ratio: Temperature difference ratio = (20℃ - 15℃) / 20℃ = 0.25. The adjustment range is then 50% * 0.25 = 12.5%, meaning that the current amplitude value of 50% needs to be adjusted upwards by 12.5%, i.e., the valve opening of the electric regulating valve needs to be adjusted to 62.5%.
[0042] Step S103: Adjust the electric regulating valve according to the adjustment range and cycle time to achieve heating in the heating area.
[0043] Specifically, it is determined whether the adjustment range is greater than the adjustment threshold; if so, the electric regulating valve is adjusted multiple times according to the adjustment threshold; after each adjustment of the electric regulating valve, the latest temperature is obtained, which represents the temperature of the heating area obtained after the cycle time after adjusting the electric regulating valve; when the latest temperature is equal to the correction temperature, the adjustment of the electric regulating valve is stopped.
[0044] It is understandable that large changes in the valve opening of the electric regulating valve can lead to significant temperature and pressure fluctuations in the heating station, main water supply pipe, and branch water supply pipe 14, potentially causing safety accidents. Therefore, it is necessary to limit the valve opening changes of the electric regulating valve each time. The aforementioned adjustment thresholds are set by the staff based on actual conditions, and each change in the valve opening of the electric regulating valve must not exceed these thresholds. For example, if the adjustment range is 20% and the current range is 50%, it needs to be adjusted from 50% to 70%. If the adjustment threshold is 5%, it means that each adjustment cannot exceed 5%, so it is necessary to adjust from 50% to 55%, 60%, 65%, and finally 70%.
[0045] In one implementation, the relationship between the adjustment range and the adjustment threshold needs to be determined. If the adjustment range is less than or equal to the adjustment threshold, it indicates a small adjustment range that will not cause significant temperature or pressure changes, and a single adjustment is sufficient. For example, with an adjustment range of 5% and an adjustment threshold of 10%, the valve opening can be increased by 5% directly. If the adjustment range is greater than the adjustment threshold, it indicates a large adjustment range that may cause significant temperature or pressure changes, requiring multiple adjustments. For example, with an adjustment range of 12% and an adjustment threshold of 5%, the first two adjustments can be made by 5% each, and the last adjustment by 2%, or the last adjustment can be made by 4%, requiring three adjustments to complete the process. Since the adjustment range is the theoretical value corresponding to the corrected temperature, the latest temperature of the heating area needs to be monitored during the adjustment of the electric solenoid valve. If the latest temperature reaches the corrected temperature, the adjustment of the electric solenoid valve can be stopped; otherwise, the adjustment of the electric solenoid valve needs to be completed. Because the heating area cannot immediately display the change after each adjustment of the electric regulating valve, a cycle time is required. After the adjusted hot water flows through the heating area, obtaining the latest temperature will accurately reflect the temperature change after the adjustment.
[0046] In another embodiment, the electric regulating valve is adjusted according to a preset adjustment threshold. After each adjustment, a new temperature is obtained, which represents the temperature of the heating area obtained after the cycle time following the adjustment of the electric regulating valve. When the new temperature reaches the correction temperature, the adjustment of the electric regulating valve is stopped. For example, if the adjustment threshold is 5%, the electric regulating valve is adjusted by 5% each time until the adjusted new temperature reaches the correction temperature, at which point the adjustment of the electric regulating valve stops.
[0047] For example, the secondary return water temperature t0 is collected by a secondary return water main pipe temperature sensor 11. The return water temperature of each heating area, i.e., the actual temperature t1, t2, ..., tn, is collected by temperature sensors installed on the zoned return water pipes of each heating area. The correction values for the return water temperature of each heating area are tc1, tc2, ..., tcn. The aforementioned actual temperature refers to the actual temperature of each heating area, while the aforementioned correction value refers to the temperature demand of users in the heating area based on the aforementioned actual temperature. For example, the correction value can be +2, indicating that the temperature will be increased based on the actual temperature, which means that the valve opening of the electric regulating valve needs to be increased. The sum of the aforementioned correction value and the aforementioned actual temperature equals the corrected temperature. The aforementioned correction value is set according to the actual situation and / or the actual demand of users in the heating area. The valve opening of the electric regulating valve can be divided into 10 stages: 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%. Then, different cycle times are set for different heating areas. The above cycle time can be set to 5 minutes, 10 minutes, 20 minutes, 30 minutes, 1 hour, etc., depending on the heating area.
[0048] First, determine the relationship between the actual temperature and the corrected temperature. If the actual temperature is higher than the corrected temperature, decrease the valve opening by one stage. For example, if the current valve opening is 50%, adjust it to 40%. After the aforementioned cycle time, obtain the latest temperature for the heating area. If the latest temperature is still higher than the corrected temperature, continue decreasing the valve opening and repeat the above process until the latest temperature is no higher than the corrected temperature. If the actual temperature is lower than the corrected temperature, increase the valve opening by one stage. For example, if the current valve opening is 60%, adjust it to 70%. After the aforementioned cycle time, obtain the latest temperature for the heating area. If the latest temperature is still lower than the corrected temperature, continue decreasing the valve opening and repeat the above process until the latest temperature is no lower than the corrected temperature. If the actual temperature equals the corrected temperature, no adjustment of the electric regulating valve is needed.
[0049] This application provides a thermal balance regulation system for a thermal pipeline network, referring to... Figure 5 The heat balance regulation system of the heating network includes: Data acquisition module 201 is used to acquire the actual temperature, corrected temperature and cycle time of the heating area.

A method for regulating the heat balance of a thermal pipeline network, characterized in that, include: The system acquires the actual temperature, corrected temperature, and cycle time of the heating area. The actual temperature reflects the temperature of the heating area, the corrected temperature reflects the temperature demand of the heating area, and the cycle time represents the time it takes for hot water to flow from the heating station into the heating area and back to the heating station. It also acquires the ambient temperature of the heating area, representing the outdoor temperature of the heating area, and determines a temperature amplitude relationship curve corresponding to the ambient temperature. This temperature amplitude relationship curve reflects the correspondence between the actual temperature and / or the corrected temperature and the adjustment amplitude. Based on the actual temperature and the corrected temperature, an adjustment range is determined. This adjustment range reflects the change in valve opening of the electric regulating valve during the transition from the actual temperature to the corrected temperature. When the adjustment range corresponding to the actual temperature is the same as the current adjustment range, the difference in adjustment range corresponding to the corrected temperature is recorded as the adjustment range. When the adjustment range corresponding to the actual temperature is different from the current adjustment range, the adjustment range is calculated based on the temperature difference ratio, where the temperature difference ratio is the ratio of the temperature difference to the actual temperature, the temperature difference is the difference between the actual temperature and the corrected temperature, and the adjustment range is the product of the temperature difference ratio and the actual temperature. Based on the adjustment range and the cycle time, the electric regulating valve is adjusted to achieve heating for the heating area.
