Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, and in particular to a method for intelligent temperature control of multi-compartment, large-volume concrete. Background Technology

[0002] During the construction of large-volume concrete, the heat released by cement hydration can easily cause a sudden rise in the internal temperature of the structure, forming a significant internal-to-surface temperature difference with the surface that dissipates heat faster. If not properly controlled and exceeding the standard limits, this will cause harmful temperature cracks, seriously threatening the structural safety and durability.

[0003] While existing technologies can achieve single-compartment, single-temperature control, they suffer from significant drawbacks in large-scale engineering projects with multiple compartments operating in parallel. Firstly, each compartment requires its own independent hot / cold water source and circulation equipment, leading to equipment redundancy, complex pipelines, high initial investment, and substantial energy consumption. Secondly, existing systems lack a global collaborative control mechanism, failing to dynamically allocate shared hot and cold resources based on real-time construction progress, temperature status, and temperature control requirements of each compartment, resulting in low resource utilization efficiency. Furthermore, current systems heavily rely on manual experience to judge mixing temperature and flow rate, exhibiting sluggish response and insufficient adjustment precision. This makes it difficult to accurately match the dynamic changes in concrete hydration heat release, potentially leading to uncontrolled fluctuations in internal surface temperature differences and even increased risks of exceeding standards, thus failing to meet the requirements for refined temperature control. Therefore, there is an urgent need to develop a novel temperature control system that can efficiently coordinate hot and cold resources across multiple compartments, achieving global intelligent dynamic allocation and automated precise control to overcome these technical bottlenecks. Summary of the Invention

[0004] This invention provides a method for intelligent temperature control of multi-compartment large-volume concrete, which solves the defects of existing multi-compartment control systems that are complex and difficult to control precisely.

[0005] This invention provides a method for intelligent temperature control of multi-compartment large-volume concrete, comprising multiple concrete compartments and a temperature control system. The temperature control system includes a controller, a hot water tank, a cold water tank, and multiple mixing tanks connected in parallel. The hot water tank and the cold water tank are both connected to the mixing tanks. The multiple concrete compartments are configured one-to-one with the multiple mixing tanks. Each concrete compartment is equipped with a circulating temperature control pipeline, which is connected to the mixing tank. The controller is used to control the temperature of the liquid medium in the mixing tank and the internal surface temperature difference between the center temperature and the surface temperature of each concrete compartment based on the intelligent control method. The intelligent temperature control method includes the following steps: The temperatures of the liquid media in the hot water tank and the cold water tank are obtained separately, and the temperatures in the hot water tank and the cold water tank are ensured to be within the set temperature range. The concrete surface temperature, concrete core temperature, and ambient temperature are obtained, and the pouring state of the concrete compartment is determined based on the concrete surface temperature, concrete core temperature, and ambient temperature. In response to the concrete placement being in a poured state, it determines whether the concrete placement is in a heating or cooling stage, obtains the heating or cooling rate, and issues a warning message when the concrete temperature exceeds the warning temperature value. The temperature and / or flow rate of the liquid medium are controlled according to a preset strategy based on the heating stage and heating rate, and the cooling stage and cooling rate, so that the internal surface temperature difference between the center temperature and the surface temperature of the concrete sump during the pouring process is within a preset range.

[0006] According to the intelligent temperature control method for multi-compartment large-volume concrete provided by the present invention, when the concrete compartment is in the heating stage, when the temperature difference between the inner surfaces is detected to be less than a set value, the cold water tank is controlled to inject cold water into the mixing tank until the temperature in the mixing tank reaches the set value. When the temperature difference between the inner surfaces is detected to be greater than the set value, the hot water tank is controlled to inject hot water into the mixing tank until the temperature in the mixing tank reaches the set value; at the same time, the temperature in the mixing tank is controlled not to be lower than the set lower limit value.

[0007] According to the intelligent temperature control method for multi-compartment large-volume concrete provided by the present invention, when the concrete compartment is in the cooling stage and the cooling rate is close to the preset cooling rate, the liquid medium in the circulating temperature control pipeline is controlled to stop flowing, and the cooling rate is continuously monitored. When the cooling rate is greater than or equal to the preset cooling rate, and the temperature difference between the inner and outer surfaces is greater than the set value, the cold water tank is controlled to inject cold water into the mixing tank until the temperature in the mixing tank reaches the set value. When the cooling rate is greater than or equal to the preset cooling rate, and the temperature difference between the inner and outer surfaces is less than the set value, the hot water tank is controlled to inject hot water into the mixing tank until the temperature in the mixing tank reaches the set value; at the same time, the temperature in the mixing tank is controlled not to exceed the set upper limit value.

[0008] According to the intelligent temperature control method for multi-compartment large-volume concrete provided by the present invention, when the concrete compartment is in the cooling stage, and when the temperature of the circulating medium in the temperature control pipeline is 25°C higher than the temperature of the concrete compartment, and the cooling rate of the concrete is still greater than or equal to the preset cooling rate, the flow velocity of the circulating medium in the temperature control pipeline is increased to the preset value.

[0009] According to the intelligent temperature control method for multi-compartment large-volume concrete provided by the present invention, when the flow rate of the circulating medium in the temperature control pipeline reaches a preset value, and the cooling rate of the concrete is still greater than or equal to the preset cooling rate, an early warning message is sent to the corresponding terminal device, and the demolding time is extended.

[0010] According to the intelligent temperature control method for multi-compartment large-volume concrete provided by the present invention, when the flow rate of the circulating medium in the temperature control pipeline reaches a preset value, and the temperature of the circulating medium in the temperature control pipeline is higher than the concrete compartment temperature by 25°C, or the temperature difference between the inlet and outlet of the temperature control pipeline is greater than the preset temperature difference, an early warning message is sent to the corresponding terminal device, and a prompt is made to cover and insulate the surface of the concrete compartment.

[0011] According to the intelligent temperature control method for multi-compartment large-volume concrete provided by the present invention, a flow direction converter is provided on the temperature control pipeline. The flow direction converter is controlled to operate within a preset time to change the flow direction of the liquid medium in the temperature control pipeline.

[0012] The intelligent temperature control method for multi-compartment large-volume concrete provided by the present invention also includes an emergency water resource allocation method: When the remaining water in the cold water tank is less than the marked water volume, it is determined that there is a shortage of cold water resources, and the remaining water resources are allocated according to the preset priority; at the same time, the flow rate of the liquid medium in the temperature control pipeline is reduced to the set minimum flow rate, and an early warning message is issued to prompt the expansion of water resources. Specifically, when the temperature difference between the inner surface and the concrete container is greater than 25°C, it is marked as having the first priority; when the container is in the heating stage and the center temperature inside the concrete container is greater than or equal to 28°C, it is marked as having the second priority.

[0013] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the intelligent temperature control method for multi-compartment large-volume concrete as described above.

[0014] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the intelligent temperature control method for multi-compartment large-volume concrete as described above.

[0015] The intelligent temperature control method for multi-compartment large-volume concrete provided by this invention corresponds one-to-one with multiple mixing chambers and multiple concrete compartments, and controls the internal surface temperature difference of each concrete compartment through a control method, thereby realizing individual control of multiple compartments, significantly improving the temperature control efficiency of multi-compartment large-volume concrete structures, thereby achieving efficient resource utilization and reducing concrete cracking.

[0026] The following is combined with Figure 1 , Figure 2As shown, this invention describes a method for intelligent temperature control of multi-compartment large-volume concrete, including multiple concrete compartments and a temperature control system 10. The temperature control system 10 includes a controller 103, a hot water tank 101, a cold water tank 102, and multiple mixing tanks 104 connected in parallel. The hot water tank 101 and the cold water tank 102 are both connected to the mixing tanks 104. The multiple concrete compartments are correspondingly arranged with the multiple mixing tanks 104. Each concrete compartment is equipped with a circulating temperature control pipeline, which is connected to the mixing tank 104. The controller 103 is used to control the temperature of the liquid medium in the mixing tank 104 and the internal surface temperature difference between the center temperature and the surface temperature of each concrete compartment based on the intelligent control method. For multiple concrete slabs, this embodiment uses a shared hot water tank 101 and cold water tank 102 for multiple mixing slabs, and uses multiple parallel mixing tanks 104 to distribute hot and cold water. This allows the temperature difference between the inner and outer surfaces of the concrete slabs to be controlled by a circulating temperature control pipeline, thus avoiding excessive temperature difference from affecting the quality of concrete pouring.

[0027] The intelligent temperature control method includes the following steps: Step S10: Obtain the temperature of the liquid medium in the hot water tank 101 and the cold water tank 102 respectively, and ensure that the temperature in the hot water tank 101 and the cold water tank 102 is within the set temperature range.

[0028] Specifically, a heating unit 1011 is provided inside the hot water tank 101. The heating unit 1011 can provide heating to the hot water tank 101 to heat the liquid medium inside the hot water tank 101. A temperature sensor is also provided inside the hot water tank 101. The temperature sensor is electrically connected to the controller 103. The temperature sensor is used to detect the temperature of the liquid inside the hot water tank 101. The temperature sensor can effectively control the heating temperature of the liquid and keep it within a preset temperature range.

[0029] Similarly, a refrigeration unit 1021 is provided in the cold water tank 102. The refrigeration unit 1021 can provide cold energy to the hot water tank 101 to realize the cooling of the liquid medium in the cold water tank 102. A temperature sensor is also provided in the cold water tank 102. The temperature sensor is electrically connected to the controller 103. The temperature sensor is used to detect the temperature of the liquid in the cold water tank 102. The temperature sensor can effectively control the heating temperature of the liquid and keep it within the preset temperature range.

[0030] Specifically, during control, the controller 103 can output a control signal based on the temperature information fed back by the temperature sensor. This control signal can then control the refrigeration unit 1021 or the heating unit 1011 to operate, thereby providing cooling or heating energy to the liquid medium in the cold water tank 102 or the hot water tank 101, thus stabilizing the temperature of the liquid medium in both tanks. For example, in the hot water tank 101, if the temperature sensor detects that the temperature is below a preset range, a start signal is sent to activate the heating unit 1011 to heat the liquid medium in the hot water tank 101, thereby achieving effective regulation and control of the liquid medium temperature in the hot water tank 101.

[0031] Step S20: Obtain the concrete surface temperature, concrete center temperature, and ambient temperature, and determine the pouring state of the concrete placement based on the concrete surface temperature, the concrete center temperature, and the ambient temperature.

[0032] Specifically, each concrete slab is equipped with an internal temperature sensor, a surface temperature sensor, and an ambient temperature sensor 105. All sensors are connected to a controller 103. The controller can determine the concrete pouring status based on the information fed back by each temperature sensor and provide status information for subsequent temperature adjustments, thereby improving the accuracy of the control.

[0033] In practice, the concrete placement status has three states: "not poured," "pouring," and "poured." "Not poured" is the initial state, while "pouring" refers to the process of pouring. In the initial state, since the concrete has not yet been poured, the system will not perform temperature control. During pouring, because the concrete has not yet solidified, there will not be a large temperature difference, nor will there be a problem of excessive temperature difference affecting the concrete quality. In the "poured" stage, the concrete has been poured and is beginning to solidify. At this time, the temperature difference between the inner and outer surfaces of the concrete will increase, and it will be affected by the external ambient temperature. This stage is the key control stage.

[0034] Furthermore, the pouring state can be determined by establishing temperature change curves or models. The specific logic is as follows: before pouring begins, the internal temperature of the concrete, the surface temperature of the concrete, and the ambient temperature are roughly the same with no significant difference. In the "poured" stage, there is no significant temperature difference between the inside and surface of the concrete, and the temperature difference with the external environment is also small. After pouring, the concrete begins to solidify. At this point, there is a certain temperature difference between the inside and surface of the concrete, and there is also a certain temperature difference with the external environment. This can be considered the "poured" stage. For example, by setting a temperature threshold, when the temperature difference between the inside and surface of the concrete exceeds the threshold, and / or when the internal temperature of the concrete and the external ambient temperature exceed the threshold, the state can be determined as "poured." At this time, the control system executes intelligent temperature control methods for regulation. This method allows for precise determination of the pouring state.

[0035] Step S30: In response to the concrete placement being in a poured state, determine whether the concrete placement is in a heating or cooling stage, and obtain the heating rate or cooling rate.

[0036] Specifically, after the system determines that it is currently in the "poured" stage, it is necessary to control the temperature of each concrete compartment to avoid excessive temperature difference affecting the pouring quality of a single concrete compartment. In this embodiment, the temperature is divided into a heating stage and a cooling stage to improve the accuracy and efficiency of subsequent processing and achieve rapid and effective temperature control.

[0037] Step S40: Based on the heating stage and heating rate, and based on the cooling stage and cooling rate, control the temperature and / or flow rate of the liquid medium according to a preset strategy, so that the internal surface temperature difference between the center temperature and the surface temperature of the concrete sump during the pouring process is within a preset range.

[0038] Specifically, different control strategies are used in the heating and cooling stages. By using different control strategies, the temperature can be regulated, thereby improving the accuracy and efficiency of temperature regulation and enhancing the quality of concrete pouring.

[0039] Understandably, in related technologies, controlling multiple concrete sections is relatively complex and difficult to achieve precise control. In this embodiment, multiple mixing tanks 104 are allocated to each concrete section, enabling individual control of each section and achieving precise control, thus improving the precision of control. Furthermore, the designed control method reduces the difficulty of control and enhances the efficiency and accuracy of temperature regulation. Moreover, compared to traditional overall control, this invention effectively divides the post-pouring heating and cooling stages, which effectively improves the accuracy and efficiency of temperature control and allows for differentiated control of multiple concrete sections, reducing the management difficulty of multiple sections and improving the accuracy of temperature regulation.

[0040] For example, such as Figure 2 As shown, there are multiple concrete compartments, each in a different state and stage of pouring. Temperature can be controlled by mixing circulating water of different temperatures in the corresponding mixing tank 104. This effectively reduces the complexity of controlling multiple compartments and enables precise and effective control for each compartment, improving the pouring quality of each concrete compartment.

[0041] In the specific setup, water pumps are installed on the outlet pipes of the cold water tank 102, hot water tank 101, and mixing tank 104. The water pumps are electrically connected to the controller 103, and return pipes are installed between the cold water tank 102, hot water tank 101, and mixing tank 104 to achieve the return of the liquid medium, thus realizing the circulation of the entire flow path. When temperature adjustment is required, a certain proportion of hot and cold water (i.e., the liquid medium) is introduced into the mixing tank 104 through the water pumps. The hot and cold water are mixed to obtain mixed temperature-regulating water at the set temperature. This mixed temperature-regulating water is then introduced into the circulating temperature-regulating pipes to achieve temperature control within the concrete slab.

[0042] Furthermore, it also includes an external mobile terminal that communicates with the controller 103. The mobile terminal can receive information and issue commands. For example, when controlling the entire system, control commands can be input through the mobile terminal. The control commands can control the operation of the entire system, and the temperature control data and working status of each concrete slab can be viewed in real time through the mobile terminal.

[0043] The determination of heating and cooling states is achieved by detecting the temperature difference between the center temperature of the concrete placement area and the outlet temperature of the circulating temperature-regulating pipe. When the outlet temperature of the circulating water is lower than the center temperature of the concrete placement area, it indicates that the concrete placement area has absorbed the temperature of the circulating water and is in the heating stage. Similarly, when the outlet temperature of the circulating water is higher than the center temperature of the concrete placement area, it indicates that the circulating temperature-regulating pipe has absorbed the temperature of the concrete placement area and is in the heating stage. At different stages, corresponding strategies are adopted based on the heating and cooling rates to control the temperature, improving the accuracy and efficiency of temperature regulation.

[0044] In the specific real-time method: In step S10, the controller 103 reads the temperature information of the temperature sensors installed in the hot water tank 101 and the cold water tank 102, and ensures that the water temperature in the hot water tank 101 is maintained at 95°C and the water temperature in the cold water tank 102 is maintained at 5°C. In step S20, the controller 103 reads the data changes of the concrete surface temperature sensor, the concrete center temperature sensor and the ambient temperature sensor 105, and determines the pouring state through the concrete placement pouring state model. In step S30, the controller 103 determines that the concrete slab is already "poured" and determines that the heating stage is when the outlet water temperature of the circulating temperature control pipeline is lower than the center temperature of the concrete slab, and the cooling stage is when the outlet water temperature of the circulating temperature control pipeline is higher than the center temperature of the concrete slab; and issues a warning message when the concrete temperature is higher than the warning temperature value of 28°C, prompting the user to adjust the temperature. In step S40, when the concrete slab is in the heating stage, when the temperature difference between the inner and outer surfaces is detected to be less than the set value, the cold water tank 102 is controlled to inject cold water into the mixing tank 104 until the temperature in the mixing tank 104 reaches the set value; wherein the set value is 25°C, and at the same time, it is ensured that the temperature of the mixed water in the mixing tank 104 is not lower than 5°C.

[0045] When the temperature difference between the inner and outer surfaces is detected to be greater than the set value, the hot water tank 101 is controlled to inject hot water into the mixing tank 104 until the temperature in the mixing tank 104 reaches the set value; at the same time, the temperature in the mixing tank 104 is controlled not to be lower than the set lower limit value, where the set value is 25℃, and the temperature of the mixed water in the mixing tank 104 is ensured not to be lower than 5℃.

[0046] In conjunction with the above embodiments, when the concrete slab is in the cooling stage and the cooling rate is close to the preset cooling rate, the liquid medium in the circulating temperature control pipeline is stopped, and the cooling rate is continuously monitored. When the cooling rate is greater than or equal to the preset cooling rate, and the internal surface temperature difference is greater than a set value, the water pump on the cold water tank 102 is controlled to inject cold water into the mixing tank 104 until the temperature in the mixing tank 104 reaches the set value. When the cooling rate is greater than or equal to the preset cooling rate, and the internal surface temperature difference is less than the set value, the water pump in the hot water tank 101 is controlled to inject hot water into the mixing tank 104 until the temperature in the mixing tank 104 reaches the set value. At the same time, the temperature in the mixing tank 104 is controlled not to exceed the set upper limit value. The preset cooling rate is 2℃ / d, the internal surface temperature difference is 25℃, and the upper limit value of the temperature in the mixing tank 104 is 95℃.

[0047] In some embodiments, temperature sensors are installed at the inlet and outlet of the circulating temperature control pipeline. The controller 103 can acquire the temperatures at the inlet and outlet of the circulating temperature control pipeline, the concrete surface temperature sensor, the concrete center temperature sensor, and the ambient temperature sensor 105. Based on the above temperature information, it can plot curves showing the changes in the center temperature, surface temperature, internal surface temperature difference, ambient temperature, and inlet / outlet temperature of the concrete slab over time. These curves enable intuitive analysis and improve the effectiveness of temperature control.

[0048] In some embodiments, when the concrete slab is in the cooling stage, and the temperature of the circulating medium in the temperature regulating pipeline is 25°C higher than the concrete slab temperature, and the concrete cooling rate is still greater than or equal to a preset cooling rate, the flow velocity of the circulating medium in the temperature regulating pipeline is increased to a preset value. The preset cooling rate is 2°C / day, and the preset flow velocity is 1.2 m / s.

[0049] In other words, when it is difficult to achieve temperature control quickly with conventional flow rates, the overall temperature control efficiency can be improved by increasing the flow rate of the mixed water.

[0050] In some embodiments, when the flow rate of the circulating medium in the temperature-regulating pipeline reaches a preset value, and the concrete cooling rate is still greater than or equal to the preset cooling rate, an early warning message is sent to the corresponding terminal device, and the demolding time is extended. The preset cooling rate is 2℃ / d, and the extended demolding time is a prompt message. This prompt message delays the demolding time, preventing premature demolding that could further increase the cooling rate and improve the effectiveness of temperature control.

[0051] In some embodiments, when the flow rate of the circulating medium in the temperature-regulating pipeline reaches a preset value, and the temperature of the circulating medium in the temperature-regulating pipeline is 25°C higher than the temperature of the concrete slab, or the temperature difference between the inlet and outlet of the temperature-regulating pipeline is greater than a preset temperature difference, an early warning message is sent to the corresponding terminal device, prompting the user to cover and insulate the surface of the concrete slab. To prevent the cooling rate from continuously increasing, sending an early warning message to prompt manual intervention through covering operations can reduce the cooling rate, achieve effective temperature control, and improve the temperature regulation effect.

[0052] In some embodiments, a flow converter is installed on the temperature-regulating pipeline. The flow converter operates within a preset time period to change the flow direction of the liquid medium within the pipeline. Correspondingly, a flow meter is installed on the temperature-regulating pipeline to measure the flow rate, thereby calculating the liquid flow velocity and enabling the detection of the liquid medium's flow velocity. Furthermore, the flow direction of the mixed water within the circulating temperature-regulating pipeline can be controlled through the flow converter, ensuring that the concrete maintains a suitable temperature distribution throughout the curing process and preventing problems caused by uneven temperature (such as cracking and insufficient strength). The dynamic adjustment function of the converter makes the cooling process more flexible and efficient, while reducing energy consumption and improving concrete quality.

[0053] In some embodiments, the intelligent temperature control method also includes an emergency water resource allocation method: When the remaining water volume in the cold water tank 102 is less than the marked water volume, it is determined that there is a shortage of cold water resources, and the remaining water resources are allocated according to the preset priority. At the same time, the flow rate of the liquid medium in the temperature regulating pipeline is reduced to the set minimum flow rate, and an early warning message is issued to prompt the expansion of water resources. Among them, when the temperature difference between the inner surface and the outer surface is greater than 25°C, it is marked as the first priority, and when it is in the heating stage and the center temperature in the concrete slab is greater than or equal to 28°C, it is marked as the second priority.

[0054] Specifically, controller 103 reads data from the concrete surface temperature sensor, concrete center temperature sensor, inlet temperature sensor, outlet temperature sensor, flow meter, ambient temperature, hot water tank 101 water temperature sensor, and cold water tank 102 water temperature sensor of each compartment, and performs the following conflict resolution operation. When the remaining cold water in cold water tank 102 is less than 20% of the total capacity, it is determined that there is a shortage of cold water resources, and the control computer immediately prioritizes the compartments that need cold water: Priority 1: Concrete compartments with an internal surface temperature difference ≥ 25℃ (marked as high-risk compartments); Priority 2: Concrete compartments with a core concrete temperature ≥ 28℃ and in the heating phase (marked as emergency compartments). Distribute remaining cold water resources according to priority: First, ensure the cold water ratio for high-risk compartments reaches the set value; allocate remaining cold water proportionally to emergency compartments; suspend cold water supply to other compartments and reduce their variable frequency pump flow rate to 0.6m / s (lower limit). Send an alert to mobile terminals: "Insufficient cold water resources, tiered control has been activated, it is recommended to expand cold water tank 102." Similarly, when hot water resources are scarce, the above priority allocation applies.

[0055] Figure 3 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 3 As shown, the electronic device may include: a processor 310, a communications interface 320, a memory 330, and a communications bus 340, wherein the processor 310, the communications interface 320, and the memory 330 communicate with each other through the communications bus 340. The processor 310 can call logic instructions in the memory 330 to execute a multi-compartment large-volume concrete temperature intelligent control method. This method includes: acquiring the temperatures of the liquid media in the hot water tank and cold water tank respectively, and ensuring that the temperatures in the hot water tank and cold water tank are within a set temperature range; acquiring the concrete surface temperature, concrete center temperature, and ambient temperature, and determining the pouring state of the concrete compartment based on the concrete surface temperature, the concrete center temperature, and the ambient temperature; in response to the concrete compartment being in a poured state, determining whether the concrete compartment is in a heating or cooling stage, and obtaining the heating rate or cooling rate; and issuing a warning message when the concrete temperature exceeds a warning temperature value; and controlling the temperature and / or flow rate of the liquid media according to a preset strategy based on the heating stage and heating rate, and based on the cooling stage and cooling rate, so that the internal surface temperature difference between the center temperature and surface temperature of the concrete compartment during pouring is within a preset range.

[0056] Furthermore, the logical instructions in the aforementioned memory 330 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.
