[0001] This application claims priority to Chinese Patent Application No. 2024119852295, filed with the Chinese Patent Office on December 31, 2024, entitled “Method, System, Device, and Storage Medium for Temperature Adjustment of Mass Concrete”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of concrete engineering technology, specifically to methods, systems, equipment, and storage media for temperature adjustment of large-volume concrete. Background Technology

[0003] Quality control of large-volume concrete pouring is one of the key technologies in construction engineering. Whether it is housing construction, public buildings or infrastructure, there are a large number of large-volume concrete pours, and the quality of their pouring is particularly critical, determining the service life and safety of the building.

[0004] Although mass concrete is widely used in construction projects, it is prone to temperature cracks during the pouring process due to its large volume and slow heat dissipation. Therefore, strict temperature control is required during construction.

[0005] The current technology for cooling large-volume concrete uses a single-pump circulating water supply system. The pump is controlled by workers, and temperature data from the large-volume concrete's measuring points are recorded and analyzed periodically by testing personnel. Water is added to the tank when needed, and corresponding measures are taken based on the temperature difference calculated by the testing personnel. This method is inefficient, energy-intensive, and heavily influenced by human and environmental factors, making it difficult to effectively guarantee the quality of the concrete. Summary of the Invention

[0006] In view of this, this disclosure provides a method, system, equipment, and storage medium for adjusting the temperature of large-volume concrete, in order to solve the problems of low efficiency, high energy consumption, many variable factors, and inability to effectively guarantee the quality of concrete when manually controlling the cooling of large-volume concrete in related technologies.

[0007] In a first aspect, this disclosure provides a method for temperature adjustment of large-volume concrete, the method being applied to an intelligent controller, the method comprising:

[0008] The temperature difference between the top and interior of the large-volume concrete, the inlet water temperature at the water pump hose, and the outlet water temperature are obtained.

[0009] The pump speed is obtained based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow rate sensor.

[0010] Determine the target water temperature based on the pump speed;

[0011] Based on the inlet water temperature and the target water temperature, the cooling water temperature control component is used to adjust the temperature of the large-volume concrete.

[0012] In this embodiment, the water pump speed is determined by acquiring the internal and external temperature difference between the top and interior of the large-volume concrete, the inlet water temperature at the water pump hose, and the outlet water temperature. Based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow rate sensor, the water pump rotation speed is obtained. The target water temperature is determined based on the water pump rotation speed. The cooling water temperature component is then controlled based on the inlet water temperature and the target water temperature to adjust the temperature of the large-volume concrete. Compared to traditional single-pump circulating water cooling, this embodiment is easier to operate, requires no manual operation, and features intelligent control and platform management. It can dynamically adjust the water pump rotation speed and water flow rate based on real-time data of the internal and external temperature difference of the large-volume concrete, the inlet water temperature, and the outlet water temperature. Simultaneously, it controls the cooling water temperature component to adjust the temperature of the large-volume concrete, achieving not only effective cooling of the large-volume concrete but also energy conservation and emission reduction, eliminating potential hazards associated with large-volume concrete, and ensuring project quality.

[0013] In one optional implementation, the pump speed is obtained based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow rate sensor, including:

[0014] The calculated flow rate is obtained based on the internal and external temperature difference, the outlet water temperature, and the inlet water temperature.

[0015] Based on the difference between the calculated flow velocity and the actual flow velocity, the target difference range in which the difference falls is obtained;

[0016] The corresponding water pump speed is determined based on the target difference range.

[0017] In this embodiment of the disclosure, the flow rate of circulating water in large-volume concrete is controlled by adjusting the speed of the water pump, thereby achieving energy saving and precise control of the water flow rate.

[0018] In one optional implementation, the calculated flow rate is obtained based on the internal and external temperature difference, the outlet water temperature, and the inlet water temperature, including:

[0019] Compare the internal and external temperature difference with the temperature difference threshold;

[0020] When the internal and external temperature difference is greater than the temperature difference threshold, it is determined that the large volume concrete needs to be cooled. The water temperature at the outlet and the water temperature at the inlet are obtained, and the flow rate is calculated based on the water temperature at the outlet and the water temperature at the inlet.

[0021] In one optional implementation, determining the target water temperature based on the pump speed includes:

[0022] Determine the target water flow velocity based on the pump speed;

[0023] The target water temperature is determined based on the target water flow velocity and the cross-sectional area of ​​the pump.

[0024] In one optional implementation, the cooling water temperature control component controls the temperature of the mass concrete based on the inlet water temperature and the target water temperature, including:

[0025] Compare the inlet water temperature with the target water temperature;

[0026] If the inlet water temperature is higher than the target water temperature, activate the cooling water temperature control unit to reduce the temperature of the large-volume concrete.

[0027] If the inlet water temperature is less than or equal to the target water temperature, shut off the cooling water temperature control unit to maintain the temperature of the large-volume concrete.

[0028] In this embodiment of the disclosure, by controlling the temperature of the circulating water in the large-volume concrete, a scientific and effective cooling effect is achieved, thereby improving the forming quality of the large-volume concrete, reducing internal cracks, eliminating potential hazards, and enhancing the quality of the project.

[0029] In one alternative implementation, the method further includes:

[0030] Upon receiving the first instruction from the water level sensor, an opening instruction is sent to the water tank inlet solenoid valve, wherein the first instruction is used to indicate that the water level is less than the standard water level value.

[0031] Upon receiving a second instruction from the water level sensor, a closing instruction is sent to the water tank inlet solenoid valve. The second instruction indicates that the water level is greater than or equal to the standard water level value.

[0032] In this embodiment of the disclosure, the opening and closing of the water tank inlet solenoid valve is realized by a water level sensor, thereby achieving efficient, energy-saving and intelligent control of cooling of large-volume concrete.

[0033] Secondly, this disclosure provides a system for adjusting the temperature of large-volume concrete, the system comprising: an intelligent control module, a temperature processing module, a cooling control module, and a water pump control module;

[0034] The temperature processing module is connected to the intelligent control module and is used to transmit the temperature difference between the top of the large volume concrete and the inside of the large volume concrete obtained from the temperature measurement point to the intelligent control module.

[0035] The water pump control module is connected to the intelligent control module and is used to transmit the inlet water temperature and outlet water temperature obtained by the temperature sensor installed at the water pump hose to the intelligent control module.

[0036] The cooling control module is connected to the intelligent control module and is used to transmit the cooling control device parameters to the intelligent control module;

[0037] The intelligent control module obtains the water pump speed based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow velocity sensor. It then sends the water pump speed to the water pump control module, enabling the water pump control module to control the water flow rate based on the water pump speed. The intelligent control module determines the target water temperature based on the water pump speed and controls the cooling water temperature component based on the inlet water temperature and the target water temperature to adjust the temperature of the large-volume concrete.

[0038] In one optional implementation, the system further includes: a water level monitoring module and a water tank inlet solenoid valve;

[0039] The water level monitoring module is connected to the intelligent control module. It is used to send a first instruction to the intelligent control module when the water level sensor in the water level monitoring module detects that the water level is lower than the water level standard value, and to send a second instruction to the intelligent control module when the water level is greater than or equal to the water level standard value.

[0040] The intelligent control module is connected to the water tank inlet solenoid valve. It is used to send an opening command to the water tank inlet solenoid valve when a first command is received, and to send a closing command to the water tank inlet solenoid valve when a second command is received.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0050] Currently, in large-volume concrete construction projects, single-pump circulating water supply is used for cooling large-volume concrete. The pumps are controlled by workers, which is inefficient, energy-intensive, and subject to significant human and environmental factors, making it difficult to effectively guarantee concrete quality. To address this issue, according to an embodiment of this disclosure, a method for controlling the temperature of large-volume concrete is provided. It should be noted that the steps shown in the flowchart can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that presented here.

[0051] This embodiment provides a method for temperature control of large-volume concrete. Figure 1 is a flowchart of the method for temperature control of large-volume concrete according to an embodiment of this disclosure. As shown in Figure 1, this process can be applied to the intelligent controller side, and the method includes the following steps:

[0052] Step S101: Obtain the temperature difference between the top of the large-volume concrete and the inside of the large-volume concrete, the water temperature at the inlet of the water pump hose, and the water temperature at the outlet.

[0053] Step S102: Obtain the pump speed based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow rate sensor.

[0054] Step S103: Determine the target water temperature based on the water pump speed;

[0055] Step S104: Control the cooling water temperature component according to the inlet water temperature and the target water temperature to adjust the temperature of the large-volume concrete.

[0056] Optionally, in this embodiment of the disclosure, temperature measuring points are provided around the large volume concrete. For example, a temperature sensor is arranged 50mm from the top and bottom of the large volume concrete, a temperature sensor is arranged at 500mm intervals in the middle, and four temperature sensors are arranged along half of the horizontal axis to obtain the temperature of the top of the concrete, the temperature inside the concrete, and the ambient temperature outside the concrete.

[0057] The intelligent controller then acquires the temperature data fed back from the temperature sensors and processes this data using the motherboard within the intelligent sensors to calculate the temperature difference between the top and interior of the large-volume concrete structure. Additionally, it calculates the temperature difference between the interior and exterior of the large-volume concrete structure to assist in adjusting its temperature.

[0058] In this embodiment of the disclosure, a temperature sensor is also arranged on the large-volume concrete inlet hose (at the connection port between the water pump control module and the hose) to obtain the inlet water temperature; and a temperature sensor is arranged at the water tank of the return hose to obtain the outlet water temperature.

[0059] A flow velocity sensor is installed inside the water pump to obtain the actual flow velocity of the water in the pump. Then, based on the internal and external temperature difference, the outlet water temperature, and the inlet water temperature, the calculated water flow velocity can be obtained. Based on the calculated flow velocity and the actual flow velocity fed back by the flow velocity sensor, the water pump speed can be obtained.

[0060] Then, based on the pump speed, the target water temperature that the water flowing in the pump needs to reach is obtained. The inlet water temperature and the target water temperature are compared to control the cooling water temperature components, such as copper cooling towers and electric fans, and thus adjust the temperature of the large-volume concrete.

[0061] In this embodiment, the water pump speed is determined by acquiring the internal and external temperature difference between the top and interior of the large-volume concrete, the inlet water temperature at the water pump hose, and the outlet water temperature. Based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow rate sensor, the water pump rotation speed is obtained. The target water temperature is determined based on the water pump rotation speed. The cooling water temperature component is then controlled based on the inlet water temperature and the target water temperature to adjust the temperature of the large-volume concrete. Compared to traditional single-pump circulating water cooling, this embodiment is easier to operate, requires no manual operation, and features intelligent control and platform management. It can dynamically adjust the water pump rotation speed and water flow rate based on real-time data of the internal and external temperature difference of the large-volume concrete, the inlet water temperature, and the outlet water temperature. Simultaneously, it controls the cooling water temperature component to adjust the temperature of the large-volume concrete, achieving not only effective cooling of the large-volume concrete but also energy conservation and emission reduction, eliminating potential hazards associated with large-volume concrete, and ensuring project quality.

[0062] In some optional implementations, the pump speed is obtained based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow rate sensor, including:

[0063] The calculated flow rate is obtained based on the internal and external temperature difference, the outlet water temperature, and the inlet water temperature.

[0064] Based on the difference between the calculated flow velocity and the actual flow velocity, the target difference range in which the difference falls is obtained;

[0065] The corresponding water pump speed is determined based on the target difference range.

[0066] Optionally, the intelligent controller compares the internal and external temperature difference with the temperature difference threshold (e.g., 25°). If the internal and external temperature difference is greater than the temperature difference threshold, it is considered that the large volume concrete needs to be cooled. At this time, the outlet water temperature and the inlet water temperature are obtained, and the average value of the two is determined based on the outlet water temperature and the inlet water temperature. The average value is then substituted into the following formula (1) to obtain the calculated flow rate.

[0067] Where V is the calculated flow velocity, Q is the water flow rate, and A is the cross-sectional area of ​​the pump.

[0068] Q is obtained from the following formula (2): Q=Q0(1+β(T-T0)) (2)

[0069] Where Q0 represents the flow rate at standard temperature T0, β represents the temperature coefficient (which can be selected according to actual conditions, such as 0.1), and T represents the average value of the outlet water temperature and the inlet water temperature. The standard temperature T0 refers to the water temperature required to remove a unit of heat when the pump pipe diameter and water flow rate are constant.

[0070] The actual flow rate can be obtained by using a flow rate sensor installed inside the water pump. Then, the difference between the calculated flow rate and the actual flow rate is calculated, and it is determined which of several difference intervals the difference falls into. Each difference interval corresponds to a water pump speed. For example, there are 3 difference intervals: interval 1: 0-5; interval 2: 6-10; interval 3: 11-15. Among them, interval 1 corresponds to a low water pump speed, interval 2 corresponds to a medium water pump speed, and interval 3 corresponds to a high water pump speed.

[0071] For example, if the difference between the calculated flow velocity and the actual flow velocity is 4, then the corresponding target difference interval is interval 2, and the corresponding pump speed is low speed.

[0072] In this embodiment of the disclosure, the flow rate of circulating water in large-volume concrete is controlled by adjusting the speed of the water pump, thereby achieving energy saving and precise control of the water flow rate.

[0073] In some alternative implementations, the target water temperature is determined based on the pump speed, including:

[0074] Determine the target water flow velocity based on the pump speed;

[0075] The target water temperature is determined based on the target water flow velocity and the cross-sectional area of ​​the pump.

[0076] Optionally, after determining the pump speed, the water flow rate is controlled based on the pump speed to obtain the target water flow rate. Then, the target water flow rate and the pump cross-sectional area are used to determine the target water temperature. The target water temperature is the standard temperature described in the above embodiment.

[0077] In some alternative implementations, the cooling water temperature control component controls the temperature of the mass concrete based on the inlet water temperature and the target water temperature, including:

[0078] Compare the inlet water temperature with the target water temperature;

[0079] If the inlet water temperature is higher than the target water temperature, activate the cooling water temperature control unit to reduce the temperature of the large-volume concrete.

[0080] If the inlet water temperature is less than or equal to the target water temperature, shut off the cooling water temperature control unit to maintain the temperature of the large-volume concrete.

[0081] Optionally, since the target water flow velocity is known once determined, and the pump pipe diameter is known once determined, the target water temperature required to remove a unit of heat can be obtained based on the target water flow velocity and the pump cross-sectional area. Then, the current inlet water temperature and the target water temperature are compared. If the inlet water temperature is higher than the target water temperature, the cooling water temperature component is activated, such as the cooling module fan, to lower the water temperature and reduce the temperature of the large-volume concrete. If the inlet water temperature is less than or equal to the target water temperature, the cooling water temperature component is deactivated to maintain the temperature of the large-volume concrete.

[0082] It should be noted that when the intelligent controller issues start or stop commands to the cooling water temperature component, it will refer to the component's own parameters, such as the load value. If the intelligent controller receives a load value for the cooling water temperature component that exceeds the maximum operating value, it will not immediately execute the start command even if the component needs to be turned on. Instead, it will wait until the intelligent controller receives the load value for the cooling water temperature component again. If the load value is lower than the maximum operating value, then the start command will be executed.

[0083] In this embodiment of the disclosure, by controlling the temperature of the circulating water in the large-volume concrete, a scientific and effective cooling effect is achieved, thereby improving the forming quality of the large-volume concrete, reducing internal cracks, eliminating potential hazards, and enhancing the quality of the project.

[0084] In some alternative implementations, the method further includes:

[0085] Upon receiving the first instruction from the water level sensor, an opening instruction is sent to the water tank inlet solenoid valve, wherein the first instruction is used to indicate that the water level is less than the standard water level value.

[0086] Upon receiving a second instruction from the water level sensor, a closing instruction is sent to the water tank inlet solenoid valve. The second instruction indicates that the water level is greater than or equal to the standard water level value.

[0087] Optionally, the water level sensor mainly monitors and feeds back the water level in the water tank, compares the measured water level height with the set water level standard value, and when it is lower than the water level standard value, it feeds back to the intelligent controller. The intelligent controller sends an opening command to the water tank inlet solenoid valve, and the external water supply solenoid valve opens (the external water supply is normally open and pressurized by default), and water begins to enter. When the water level height reaches or exceeds the water level standard value, it feeds back to the intelligent controller, and the intelligent controller sends a closing command to the water tank inlet solenoid valve, and the solenoid valve closes, stopping the water entering.

[0088] The reduction of water in the tank is mainly due to evaporation, leakage at pipe joints, and localized damage and seepage. When the water tank inlet solenoid valve is opened and the water level does not rise or rises slowly, the intelligent controller can determine that there is a pipe damage and leakage, and can issue an alarm or send a message to maintenance personnel.

[0089] In this embodiment of the disclosure, the opening and closing of the water tank inlet solenoid valve is realized by a water level sensor, thereby achieving efficient, energy-saving and intelligent control of cooling of large-volume concrete.

[0090] In this embodiment, a system for adjusting the temperature of large-volume concrete is also provided, as shown in Figure 2. The system includes: an intelligent control module 1, a temperature processing module 2, a cooling control module 3, and a water pump control module 4.

[0091] Temperature processing module 2 is connected to intelligent control module 1 and is used to transmit the temperature difference between the top of the large volume concrete and the inside of the large volume concrete obtained at the temperature measuring point of the large volume concrete to intelligent control module 1.

[0092] The water pump control module 4 is connected to the intelligent control module 1, and is used to transmit the inlet water temperature and outlet water temperature obtained by the temperature sensor installed at the water pump hose to the intelligent control module 1.

[0093] The cooling control module 3 is connected to the intelligent control module 1, and is used by the cooling control module 3 to transmit the parameters of the cooling water temperature component in the cooling control module to the intelligent control module 1.

[0094] The intelligent control module 1 obtains the water pump speed based on the internal and external temperature difference, the outlet water temperature, the inlet water temperature, and the actual flow rate fed back by the flow rate sensor, and sends the water pump speed to the water pump control module 4, so that the water pump control module 4 controls the water flow rate based on the water pump speed; the intelligent control module 1 determines the target water temperature based on the water pump speed, and controls the cooling water temperature component based on the inlet water temperature and the target water temperature to adjust the temperature of the large volume concrete.

[0095] It should be noted that the temperature processing module 2 includes components such as temperature sensors, mainly consisting of temperature sensors (using the most advanced contact temperature sensors on the market), motherboard, program algorithm, power supply, display screen, connecting cables, etc. It mainly collects and processes temperature data from various temperature measurement points of the large-volume concrete and circulating water temperature data, analyzes the temperature measurement data arranged inside the large-volume concrete, calculates the temperature difference between the middle and surface of the large-volume concrete and the temperature difference between the surface of the large-volume concrete and the environment, and provides feedback data to the intelligent control module 1.

[0096] The water pump control module 4 mainly consists of a pipeline-type variable frequency automatic start-stop axial flow pump, a flow sensor, a power supply, connecting wires, and a protective housing. It mainly controls the start-up and shutdown of the water pump and its speed, and collects and processes the water pump speed data, water flow rate, and water temperature data, and feeds them back to the intelligent control module 1.

[0097] The cooling control module 3 includes components such as a copper cooling tower and an electric fan, and receives start or stop commands from the intelligent control module 1 (referring to the control of the operation of the cooling components).

[0098] In some optional implementations, as shown in Figure 2, the system also includes: a water level monitoring module 5 and a water tank inlet solenoid valve 6;

[0099] The water level monitoring module 5 is connected to the intelligent control module 1. When the water level sensor in the water level monitoring module 5 detects that the water level is less than the standard water level value, the water level monitoring module 5 sends a first instruction to the intelligent control module 1. When the water level monitoring module 5 detects that the water level is greater than or equal to the standard water level value, the water level monitoring module 5 sends a second instruction to the intelligent control module 1.

[0100] The intelligent control module 1 is connected to the water tank inlet solenoid valve 6. When the intelligent control module 1 receives a first instruction, it sends an opening instruction to the water tank inlet solenoid valve 6. When the intelligent control module 1 receives a second instruction, it sends a closing instruction to the water tank inlet solenoid valve 6.

[0101] It should be noted that the water level monitoring module 5 includes components such as water level sensors, which mainly monitor the water level in the water tank in real time, process the data, and feed it back to the intelligent control module 1.

[0102] Based on the above embodiments, the following description is provided: The intelligent control module includes a motherboard (with a processor containing AI functions), a touch screen, voice broadcasting, and other components. It mainly processes the data of each functional module and dynamically adjusts the water pump flow rate, the opening and closing of the water tank electronic valve, and the start, stop, and speed of the cooling tower or fan according to the set limits for the temperature difference between the inside and outside of the large-volume concrete and the outside environment. It displays the location of each temperature measuring point in real time, the range and results of temperature control, and provides timely warnings when components malfunction. It automatically feeds real-time data back to the platform, enabling autonomous control, remote control, and manual control functions.

[0103] Operating Mechanism of Intelligent Control Module 1: Intelligent Control Module 1 sets temperature differences for various parts within the large-volume concrete, sets standard and lower limits for the water level in the water tank, and sets low, medium, and high limits for the water pump speed. Through data processing and analysis, it issues commands to adjust the water pump speed via frequency conversion, to start and stop the cooling tower or fan, and to open and close the inlet solenoid valve. It compares and analyzes the differences fed back by Temperature Processing Module 2, processes them through an AI chip, calculates the optimal flow rate (represented by water pump speed) and water temperature, and dynamically controls the opening and closing of the inlet solenoid valve based on data fed back by the water level sensor, achieving efficient, energy-saving, and intelligent control of cooling the large-volume concrete.

[0104] The intelligent control module 1 acts as the "brain" of the entire device, processing and analyzing data from each module, and dynamically adjusting each module to control the flow rate and temperature of the circulating water in the large-volume concrete, thereby achieving a scientific and effective cooling effect and improving the forming quality of the large-volume concrete.
