Description

Technical Field

[0001] This application relates to the field of concrete curing technology, and in particular to a concrete curing method, control equipment and storage medium. Background Technology

[0002] During the hardening process of concrete components, the hydration of cement generates a large amount of heat. When the core temperature of the concrete component is rising, the internal heat accumulates, leading to an excessive temperature difference between the inside and outside of the component, which in turn makes the surface of the concrete component prone to tensile cracking. Conversely, when the core temperature of the concrete component is cooling down, the surface of the component dissipates heat too quickly, resulting in excessive cooling shrinkage stress, which also easily leads to cracks in the concrete component.

[0003] Currently, traditional concrete curing methods use pre-embedded cooling water pipes to dissipate heat from concrete components, thereby achieving the curing of concrete. However, the curing function of the above scheme is fixed and cannot adapt to the dynamic thermal management needs of concrete components. The temperature control is not precise, which leads to low precision in concrete curing and a higher risk of cracks in concrete components. Summary of the Invention

[0004] This application provides a concrete curing method, control equipment, and storage medium, which realizes the curing function of concrete components and improves the accuracy of concrete curing, thereby solving the problem of low accuracy in concrete curing in the prior art.

[0005] In a first aspect, embodiments of this application provide a concrete curing method, which is applied to a control device in a curing system. The curing system further includes a curing device that covers the surface of a concrete component. The method includes: predicting the target temperature field characteristic data of the concrete component under the corresponding curing mode at the next moment based on a preset medium efficiency factor for each curing mode and temperature field data of the concrete component at the previous moment and at the current moment; determining the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment based on the target temperature field characteristic data corresponding to each curing mode, and determining a target curing mode from multiple curing modes based on the comprehensive thermal stress risk value; and switching the current curing mode of the curing device to the target curing mode so that the curing device uses the curing medium corresponding to the target curing mode to cure the concrete component.

[0006] In this embodiment, based on the preset medium efficiency factor of each curing mode and the temperature field data of the concrete component at the previous moment and the current moment, the target temperature field characteristic data of the concrete component at the next moment under the corresponding curing mode is predicted. This can improve the prediction accuracy of the target temperature field characteristic data of the concrete component at the next moment under the corresponding curing mode. Then, based on the target temperature field characteristic data corresponding to each curing mode, the comprehensive thermal stress risk value of the concrete component at the next moment under the corresponding curing mode is determined. Based on the comprehensive thermal stress risk value, the target curing mode is determined from multiple curing modes. This can determine the optimal curing mode at the next moment. Then, the current curing mode of the curing device is switched to the target curing mode so that the curing device uses the curing medium corresponding to the target curing mode to cure the concrete component. In the above technical solution, the curing device has multiple curing modes. By actively switching the curing modes of the curing device, the same curing device can reversibly and quickly switch between multiple curing modes. Furthermore, by switching the current curing mode of the curing device to the target curing mode, the curing device can adapt to the thermal management requirements (i.e., curing requirements) of the concrete component at the next moment, thereby improving the temperature control accuracy of the curing device and accurately matching the dynamic thermal management requirements of the concrete component at different hydration stages. This improves the accuracy of concrete curing and reduces the risk of cracks in the concrete component.

The curing system further includes the curing device, which covers the surface of a concrete component. The device includes: a prediction module, used to predict the target temperature field characteristic data of the concrete component in the corresponding curing mode at the next moment based on a preset medium efficiency factor for each curing mode and the temperature field data of the concrete component at the previous moment and the current moment; a determination module, used to determine the comprehensive thermal stress risk value of the concrete component in the corresponding curing mode at the next moment based on the target temperature field characteristic data corresponding to each curing mode, and to determine the target curing mode from multiple curing modes based on the comprehensive thermal stress risk value; and a switching module, used to switch the current curing mode of the curing device to the target curing mode, so that the curing device uses the curing medium corresponding to the target curing mode to cure the concrete component.

[0018] Figure 1 This is a schematic flowchart of a concrete curing method provided in this application embodiment. This embodiment can be applied to scenarios requiring the curing of concrete components. The concrete curing method provided in this embodiment can be executed by the concrete curing device provided in this application embodiment, which can be implemented through software and / or hardware. In a specific embodiment, the concrete curing device can be integrated into a curing system, specifically into the control equipment of the curing system. The executing entity of this method can be the control equipment in the curing system.

[0019] In one specific embodiment, the maintenance system includes control equipment, maintenance devices, and multiple temperature sensors.

[0020] The control equipment is used to acquire the temperature detected by the temperature sensor and to control the maintenance device.

[0021] Multiple temperature sensors are deployed in the environment and at the core and surface of the concrete structure to collect temperature data in real time.

[0022] Curing devices are applied to the surface of concrete components to cure them.

[0023] See Figure 1 The concrete curing method in this embodiment includes, but is not limited to, the following steps: S110. Based on the preset medium efficiency factor of each curing mode and the temperature field data of the concrete component at the previous moment and the temperature field data at the current moment, predict the target temperature field characteristic data of the concrete component at the next moment under the corresponding curing mode.

[0024] Among them, concrete components are cast from concrete, have a certain geometric shape and load-bearing capacity, and are used as load-bearing units in structural systems such as buildings and bridges. The concrete components in the embodiments of this application can be large-volume concrete components.

[0025] Temperature field data consists of the temperature of the concrete component at various locations in space, including the internal core temperature and surface temperature of the concrete component; the internal core temperature is the temperature at the internal core location of the concrete component, and the surface temperature is the temperature at the surface detection point of the concrete component.

[0026] The curing device has multiple curing modes, namely high-efficiency uniform heating mode, high-efficiency heat preservation mode, and intelligent buffer mode; and each curing mode corresponds to a curing medium; the curing medium is a substance or fluid carrier used to dissipate heat from concrete components, maintain temperature, and isolate environmental interference during the curing process of concrete components, thereby achieving curing purposes such as temperature control and crack prevention.

[0027] Optionally, the curing medium can include high thermal conductivity media, low thermal conductivity media, and phase change material media, etc. That is, the curing medium corresponding to the high efficiency heat equalization mode is a high thermal conductivity media, which is used to quickly remove the internal heat of the concrete component and solve the problem of excessive internal and external temperature difference, such as water; the curing medium corresponding to the high efficiency heat preservation mode is a low thermal conductivity media, which is used to form a heat preservation layer on the surface of the concrete component and solve the problem of excessive surface cooling, such as air; the curing medium corresponding to the intelligent buffer mode is a phase change material media, which, through the latent heat of phase change, "shaving the peak" (i.e., absorbing heat to suppress temperature rise) during the heating stage of the concrete component and "filling the valley" (i.e. releasing heat to delay cooling) during the cooling stage of the concrete component, is specifically used to deal with drastic temperature changes or specific temperature control targets that are difficult to handle by traditional linear methods.

[0028] Temperature field characteristic data is a set of key characteristic parameters determined based on temperature field data, including the internal and external temperature difference and the surface temperature change rate. Target temperature field characteristic data is the temperature field characteristic data of the concrete component under the curing action of a specific curing mode of the curing device at the next time step, including the target internal and external temperature difference and the target surface temperature change rate.

[0029] The preset medium efficiency factor is used to characterize the degree to which the curing medium effectively performs its curing function on concrete components.

[0030] Specifically, it is possible to acquire temperature field data obtained by temperature sensors from the concrete component at the previous moment and temperature field data obtained by temperature sensors from the concrete component at the current moment, namely the internal core temperature and surface temperature, and to acquire the preset medium efficiency factor for each curing mode. For example, the preset medium efficiency factor input by the curing personnel for each curing mode based on the current engineering conditions. The current engineering conditions include the current season, the current ambient temperature and humidity, and the geometric parameters (i.e., length, width, and height) and model of the concrete component. The ambient temperature can be obtained based on the temperature sensor located in the environment, and the ambient humidity can be obtained based on the humidity sensor located in the environment.

[0031] Next, based on the preset medium efficiency factor of each curing mode, the temperature field data of the previous moment, and the temperature field data of the current moment, the target temperature field characteristic data of the concrete component in the corresponding curing mode at the next moment is predicted. For example, based on the preset medium efficiency factor of each curing mode, the internal core temperature and surface temperature of the previous moment, and the internal core temperature and surface temperature of the current moment, the first preset mapping relationship can be queried to obtain the target internal and external temperature difference and the target surface temperature change rate of the concrete component in the corresponding curing mode at the next moment, thereby obtaining the target temperature field characteristic data of the concrete component in each curing mode at the next moment. The first preset mapping relationship includes the correspondence between the preset medium efficiency factor of the curing mode, the temperature field data of the previous moment, the temperature field data of the current moment, and the target temperature field characteristic data of the next moment. The first preset mapping relationship can be determined through multiple calibration tests.

[0032] S120. Based on the target temperature field characteristic data corresponding to each curing mode, determine the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment, and determine the target curing mode from multiple curing modes based on the comprehensive thermal stress risk value.

[0033] The comprehensive thermal stress risk value is used to characterize the risk of cracking, deformation, and structural damage to concrete components caused by thermal stress due to temperature changes. A lower comprehensive thermal stress risk value indicates a better curing capability of the corresponding curing mode, meaning a lower risk of cracking, deformation, and structural damage to the concrete component under the curing action of the corresponding mode. The target curing mode is the one with the lowest comprehensive thermal stress risk value among multiple curing modes.

[0034] Specifically, after obtaining the target temperature field characteristic data of the concrete component under each curing mode at the next moment, the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment can be determined based on the target temperature field characteristic data corresponding to each curing mode. That is, the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment can be obtained by querying the second preset mapping relationship based on the target internal and external temperature difference and the target surface temperature change rate of the concrete component under each curing mode at the next moment. The second preset mapping relationship includes the correspondence between the internal and external temperature difference, the surface temperature change rate, and the comprehensive thermal stress risk value at the same moment, and the second preset mapping relationship can be determined through multiple calibration tests.

[0035] Then, the maintenance mode with the lowest overall thermal stress risk value among the multiple maintenance modes is determined as the target maintenance mode.

[0036] S130. Switch the current curing mode of the curing device to the target curing mode so that the curing device can use the curing medium corresponding to the target curing mode to cure the concrete component.

[0037] Specifically, after determining the target curing mode, the current curing mode of the curing device can be detected. When the current curing mode differs from the target curing mode, the curing device is controlled to switch the current curing mode to the target curing mode. That is, the current curing medium inside the curing device is switched to the curing medium corresponding to the target curing mode, where the current curing medium is the curing medium corresponding to the current curing mode. Afterward, the curing device can use the curing medium corresponding to the target curing mode to cure the concrete component.

[0038] The technical solution of this application embodiment predicts the target temperature field characteristic data of the concrete component under the corresponding curing mode at the next moment based on the preset medium efficiency factor of each curing mode and the temperature field data of the concrete component at the previous moment and the current moment. This can improve the prediction accuracy of the target temperature field characteristic data of the concrete component under the corresponding curing mode at the next moment. Then, based on the target temperature field characteristic data corresponding to each curing mode, the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment is determined. Based on the comprehensive thermal stress risk value, the target curing mode is determined from multiple curing modes. This can determine the optimal curing mode at the next moment. Then, the current curing mode of the curing device is switched to the target curing mode so that the curing device uses the curing medium corresponding to the target curing mode to cure the concrete component. In the above technical solution, the curing device has multiple curing modes. By actively switching the curing modes of the curing device, the same curing device can reversibly and quickly switch between multiple curing modes. Furthermore, by switching the current curing mode of the curing device to the target curing mode, the curing device can adapt to the thermal management requirements (i.e., curing requirements) of the concrete component at the next moment, thereby improving the temperature control accuracy of the curing device and accurately matching the dynamic thermal management requirements of the concrete component at different hydration stages. This improves the accuracy of concrete curing and reduces the risk of cracks in the concrete component.

[0039] The following further describes a concrete curing method provided by an embodiment of this application. Figure 2 This is another schematic flowchart of the concrete curing method provided in this application. The embodiments of this application are optimizations based on the above embodiments. See also... Figure 2 The method in this embodiment includes, but is not limited to, the following steps: S210. Based on the temperature field data of the previous moment and the temperature field data of the current moment, predict the theoretical temperature field data of the concrete component at the next moment.

[0040] Among them, the theoretical temperature field data is the temperature field data of the concrete component at the next moment before it is cured by the curing device, including the theoretical internal core temperature and the theoretical surface temperature.

[0041] Specifically, the time interval between the current moment and the previous moment is calculated and denoted as the sampling time interval. The sampling time interval is the time difference between adjacent sampling moments, that is, the time interval between the next moment and the current moment is also the sampling time interval. For example, the value range of the sampling time interval can be [10 minutes, 60 minutes]. Second, the rate of change of the current core temperature is determined based on the internal core temperature at the current moment and the internal core temperature at the previous moment. That is, the difference between the internal core temperature at the current moment and the internal core temperature at the previous moment is calculated, and the ratio of this difference to the sampling time interval is calculated to obtain the rate of change of the current core temperature. Then, the rate of change of the current core temperature is used as the rate of change of the internal core temperature between the current moment and the next moment. Thus, the theoretical internal core temperature of the concrete component at the next moment is predicted based on the rate of change of the current core temperature and the internal core temperature at the current moment. That is, the product of the rate of change of the current core temperature and the sampling time interval is calculated, and the sum of this product and the internal core temperature at the current moment is calculated to obtain the theoretical internal core temperature of the concrete component at the next moment.

[0042] Then, the current surface temperature change rate is determined based on the surface temperature at the current moment and the surface temperature at the previous moment. That is, the difference between the surface temperature at the current moment and the surface temperature at the previous moment is calculated, and the ratio of this difference to the sampling time interval is calculated to obtain the current surface temperature change rate. After that, the current surface temperature change rate is used as the rate of change of surface temperature between the current moment and the next moment. Thus, the theoretical surface temperature of the concrete member at the next moment is predicted based on the current surface temperature change rate and the surface temperature at the current moment. That is, the product of the current surface temperature change rate and the sampling time interval is calculated, and the sum of this product and the surface temperature at the current moment is calculated to obtain the theoretical surface temperature of the concrete member at the next moment.

[0043] In this embodiment, by using the current core temperature change rate as the rate of change of the internal core temperature between the current time and the next time, and by using the current surface temperature change rate as the rate of change of the surface temperature between the current time and the next time, the prediction accuracy and prediction efficiency of the theoretical temperature field data for the next time can be improved.

[0044] S220. Determine the theoretical temperature field characteristic data of the concrete member at the next moment based on the theoretical temperature field data at the next moment.

[0045] Among them, the theoretical temperature field characteristic data are the temperature field characteristic data of the concrete component at the next moment without the curing effect of the curing device, including the theoretical internal and external temperature difference and the theoretical surface temperature change rate.

[0046] Specifically, after obtaining the theoretical temperature field data of the concrete component at the next moment, the theoretical internal and external temperature difference of the concrete component at the next moment can be determined based on the theoretical internal core temperature and theoretical surface temperature at the next moment. That is, the difference between the theoretical internal core temperature and the theoretical surface temperature at the next moment can be calculated to obtain the theoretical internal and external temperature difference of the concrete component at the next moment. Then, based on the theoretical surface temperature at the next moment and the surface temperature at the current moment, the theoretical surface temperature change rate of the concrete component at the next moment can be determined. That is, the difference between the theoretical surface temperature at the next moment and the surface temperature at the current moment can be calculated, and the ratio of this difference to the sampling time interval can be calculated to obtain the theoretical surface temperature change rate of the concrete component at the next moment. This can improve the calculation efficiency and accuracy of the theoretical temperature field characteristic data, and provide an accurate data foundation for subsequently determining the target temperature field characteristic data.

[0047] Optionally, the preset medium performance factor may include preset temperature difference homogenization performance and preset surface temperature stabilization performance, and different curing modes correspond to different preset medium performance factors; wherein, the preset temperature difference homogenization performance is used to characterize the performance of the curing device in reducing the internal and external temperature difference of the concrete component under a specific curing mode, and the preset surface temperature stabilization performance is used to characterize the performance of the curing device in suppressing the surface temperature change of the concrete component under a specific curing mode.

[0048] Optionally, the steps for determining the preset medium performance factor for each curing mode are as follows: obtain the engineering condition of the concrete component at the current moment to obtain the current engineering condition; match the current engineering condition with each engineering condition in the medium characteristic database to obtain the matched engineering condition, and determine the medium performance factor of each curing mode corresponding to the matched engineering condition as the preset medium performance factor of the corresponding curing mode.

[0049] The media characteristic database includes multiple engineering conditions and the media performance factor for each maintenance mode corresponding to each engineering condition.

[0050] Specifically, the system can obtain the current season, ambient temperature and humidity, as well as the geometric parameters and model of the concrete components to determine the current engineering condition. Next, it matches the current engineering condition with each engineering condition in the media characteristic database to obtain a matching engineering condition. Specifically, it vectorizes each engineering condition in both the current and media characteristic databases and calculates the similarity between the vectorized current engineering condition and each vectorized engineering condition in the media characteristic database. Then, the engineering condition with the highest similarity score (greater than a preset similarity threshold) is identified as the matching engineering condition. The preset similarity threshold is a pre-set minimum similarity score used to determine the match between two engineering conditions.

[0051] When the matched engineering condition is not empty, the media performance factor of each maintenance mode corresponding to the matched engineering condition is determined as the preset media performance factor of the corresponding maintenance mode under the current engineering condition. This can improve the efficiency and accuracy of determining the preset media performance factor.

[0052] When the matching project conditions are empty, on-site calibration tests are conducted on the current project to determine the preset medium performance factor for each maintenance mode under the current project conditions. The calibration test steps are as follows, including Sa1-Sa3: Sa1, determine the first internal and external temperature difference and the first surface temperature change rate of the concrete component at each moment within the preset calibration time period under the reference mode.

[0053] Among them, the preset calibration time is the pre-set calibration test duration; the reference mode is the mode in which the surface of the concrete component is not cured by a curing device, or the mode in which there is no curing medium inside the curing device.

[0054] Specifically, the internal core temperature and surface temperature of the concrete component at each moment within a preset calibration time under the reference mode are obtained. Then, the difference between the internal core temperature and surface temperature at each moment is calculated to obtain the first internal and external temperature difference at the corresponding moment. The rate of change between the surface temperature at each moment and the surface temperature at the previous moment is calculated to obtain the first surface temperature change rate at the corresponding moment.

[0055] Sa2, determine the second internal and external temperature difference and the second surface temperature change rate of the concrete component at each moment within the preset calibration time period under each curing mode.

[0056] Specifically, each of the various curing modes is selected as the current curing mode, the curing mode of the curing device is switched to the current curing mode, and the internal core temperature and surface temperature of the concrete component are detected at each moment within the preset calibration time. Then, the difference between the internal core temperature and the surface temperature at each moment is calculated to obtain the second internal and external temperature difference at the corresponding moment. The rate of change between the surface temperature at each moment and the surface temperature at the previous moment is calculated to obtain the second surface temperature change rate at the corresponding moment.

[0057] Sa3. Based on the first internal and external temperature difference at each moment within the preset calibration period and the second internal and external temperature difference corresponding to each maintenance mode, determine the preset temperature difference homogenization efficiency of the corresponding maintenance mode under the current engineering conditions, and based on the first surface temperature change rate at each moment within the preset calibration period and the second surface temperature change rate corresponding to each maintenance mode, determine the preset surface temperature stabilization efficiency of the corresponding maintenance mode under the current engineering conditions.

[0058] Specifically, each of the various curing modes is selected as the current curing mode. The ratio of the second internal and external temperature difference of the concrete component under the current curing mode to the first internal and external temperature difference at each moment within the preset calibration period is calculated to obtain the initial temperature difference homogenization efficiency at the corresponding moment. The average value of the initial temperature difference homogenization efficiency at all moments within the preset calibration period is calculated to obtain the preset temperature difference homogenization efficiency of the current curing mode under the current engineering conditions. Then, the ratio of the second surface temperature change rate of the concrete component under the current curing mode to the first surface temperature change rate at each moment within the preset calibration period is calculated to obtain the initial surface temperature stabilization efficiency at the corresponding moment. The average value of the initial surface temperature stabilization efficiency at all moments within the preset calibration period is calculated to obtain the preset surface temperature stabilization efficiency of the current curing mode under the current engineering conditions.

[0059] Then, the current engineering conditions and the preset media performance factors for each corresponding maintenance mode are added to the media characteristic database to enrich the media characteristic database.

[0060] In this embodiment, on-site calibration can ensure optimal matching between the preset medium performance factor and the current engineering conditions, enabling the maintenance system to sense and adapt to differences in specific engineering materials and environment, thereby further improving the maintenance effect.

[0061] It should be noted that the determination of the preset medium performance factor for each curing mode is performed before S210, that is, the on-site calibration test is performed in the early stage of curing concrete components using the curing device.

[0062] S230. The theoretical temperature field characteristic data for the next moment is corrected by using the preset medium efficiency factor of each curing mode, so as to obtain the target temperature field characteristic data of the concrete component under the corresponding curing mode for the next moment.

[0063] Specifically, each of the various curing modes is selected as the current curing mode. Based on the preset temperature difference homogenization efficiency of the current curing mode, the theoretical internal and external temperature difference at the next moment is corrected to obtain the target internal and external temperature difference of the concrete component at the next moment under the current curing mode. That is, the product of the preset temperature difference homogenization efficiency of the current curing mode and the theoretical internal and external temperature difference at the next moment is calculated to obtain the target internal and external temperature difference of the concrete component at the next moment under the current curing mode.

[0064] Then, based on the preset surface temperature stabilization efficiency of the current curing mode, the theoretical surface temperature change rate at the next moment is corrected to obtain the target surface temperature change rate of the concrete component at the next moment under the current curing mode. That is, the product of the preset surface temperature stabilization efficiency of the current curing mode and the theoretical surface temperature change rate at the next moment is calculated to obtain the target surface temperature change rate of the concrete component at the next moment under the current curing mode. This can improve the correction efficiency and accuracy, thereby improving the calculation efficiency and accuracy of the target temperature field characteristic data at the next moment, and providing an accurate data basis for subsequently determining the comprehensive thermal stress risk value.

[0065] S240. Based on the target temperature field characteristic data corresponding to each curing mode, determine the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment, and determine the target curing mode from multiple curing modes based on the comprehensive thermal stress risk value.

[0066] Specifically, based on the target temperature field characteristic data corresponding to each curing mode, the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment is determined, including Sb1-Sb3: Sb1. Determine the temperature evolution stage of the concrete member based on the theoretical internal core temperature at the next moment and the internal core temperature at the current moment, and determine the time-varying weight coefficient at the next moment based on the temperature evolution stage.

[0067] The temperature evolution stage includes a heating stage and a cooling stage. The time-varying weighting coefficient is used to reflect the contribution of the surface temperature change rate to the comprehensive thermal stress risk value at a specific temperature evolution stage.

[0068] Specifically, when the theoretical internal core temperature at the next moment is greater than the internal core temperature at the current moment, the temperature evolution stage of the concrete component is determined to be the heating stage; when the theoretical internal core temperature at the next moment is less than the internal core temperature at the current moment, the temperature evolution stage of the concrete component is determined to be the cooling stage. In this embodiment, it is assumed that the internal core temperature of the concrete component will change between adjacent sampling moments.

[0069] Then, the time-varying weight coefficient for the next moment is determined based on the temperature evolution stage. That is, the corresponding time-varying weight coefficient can be obtained by querying the third preset mapping relationship based on the temperature evolution stage. The third preset mapping relationship includes the correspondence between the temperature evolution stage and the time-varying weight coefficient. The third preset mapping relationship can be determined through multiple calibration experiments. Furthermore, the time-varying weight coefficient corresponding to the heating stage is a smaller value to focus on the control of the internal and external temperature difference; the time-varying weight coefficient corresponding to the cooling stage is a larger value to focus on the control of the temperature change rate.

[0070] Sb2, Determine the critical internal and external temperature difference of the concrete member at the next moment.

[0071] Among them, the internal and external critical temperature difference is the temperature difference that allows the concrete component to just reach the critical state of cracking due to temperature stress.

[0072] Specifically, the tensile strength of a concrete member at the next moment can be determined, where tensile strength is used to characterize the ability of a concrete member to resist tensile failure at a specific moment.

[0073] Specifically, a reference curve for the tensile strength of the concrete mix used in the concrete component can be obtained. This reference curve is a curve showing the change of tensile strength over time for the concrete mix used in the concrete component, obtained in advance through experiments or standard models. The horizontal axis represents time, the vertical axis represents tensile strength, and the origin is the start time of the hydration heat reaction. Next, the start time of the hydration heat reaction of the concrete component is determined, and the start time of the hydration heat reaction is aligned with the origin of the tensile strength reference curve. Based on the next time moment, the tensile strength reference curve is queried to obtain the tensile strength at the next time moment. The start time of the hydration heat reaction is the moment when the difference between the internal core temperature of the concrete component and the internal core temperature at the previous time moment is greater than a set threshold. The set threshold is a pre-set minimum temperature difference used to determine the change in the internal core temperature.

[0074] Next, the elastic modulus of the concrete member at the next moment can be determined, where the elastic modulus is the stiffness of the concrete member at a specific moment.

[0075] Specifically, the elastic modulus reference curve corresponding to the concrete mix proportion used in the concrete component can be obtained. The elastic modulus reference curve is a curve showing the change of the elastic modulus of the concrete mix proportion used in the concrete component over time, which is obtained in advance through experiments or standard models. The horizontal axis is time, the vertical axis is elastic modulus, and the origin is the start time of the hydration heat reaction. Then, the start time of the hydration heat reaction of the concrete component can be aligned with the origin of the elastic modulus reference curve. Based on the next time, the elastic modulus of the next time can be obtained by querying the elastic modulus reference curve.

[0076] Then, based on the preset Poisson's ratio and preset thermal expansion coefficient of the concrete member, as well as the tensile strength and elastic modulus at the next moment, the critical internal and external temperature difference of the concrete member at the next moment is determined. The preset Poisson's ratio is the ratio of the transverse shrinkage strain to the longitudinal elongation strain of the concrete member when subjected to uniaxial tension, and the preset thermal expansion coefficient is the amount of expansion per unit length of the concrete member for every 1 degree Celsius increase in temperature. The preset Poisson's ratio and preset thermal expansion coefficient of the concrete member are fixed values.

[0077] Specifically, the difference between 1 and the preset Poisson's ratio can be calculated, and the product of the tensile strength at the next moment and the difference can be calculated and recorded as the first product. Then, the product of the elastic modulus at the next moment and the preset thermal expansion coefficient can be calculated and recorded as the second product. The ratio of the first product to the second product can be calculated to obtain the critical internal and external temperature difference of the concrete component at the next moment.

[0078] Optionally, the formula for calculating the internal and external critical temperature difference is as follows: ,in, Let t be the critical internal and external temperature difference at time t, ft(t) be the tensile strength at time t, ν be the preset Poisson's ratio, E(t) be the elastic modulus at time t, and α be the preset coefficient of thermal expansion.

[0079] In this embodiment, the calculation efficiency and accuracy of the critical internal and external temperature difference of the concrete component at the next moment can be improved, providing an accurate data basis for subsequent calculation of the comprehensive thermal stress risk value.

[0080] Sb3. Based on the maximum surface temperature change rate, the target temperature field characteristic data corresponding to each curing mode, and the time-varying weighting coefficient and internal and external critical temperature difference at the next moment, the comprehensive thermal stress risk value of the concrete component under the corresponding curing mode at the next moment is determined.

[0081] Specifically, the maximum surface temperature change rate set in advance for the concrete component can be obtained. Then, each of the various curing modes is selected as the current curing mode. The ratio of the target internal and external temperature difference to the internal and external critical temperature difference corresponding to the current curing mode at the next moment is calculated to obtain the first ratio. The ratio of the target surface temperature change rate to the maximum surface temperature change rate corresponding to the current curing mode at the next moment is calculated to obtain the second ratio. Then, the product of the time-varying weight coefficient at the next moment and the second ratio is calculated, and the sum of the product and the first ratio is calculated to obtain the comprehensive thermal stress risk value of the concrete component at the next moment under the current curing mode.

[0082] Optionally, the formula for calculating the comprehensive thermal stress risk value of the current maintenance mode is as follows: Where R(t) is the comprehensive thermal stress risk value of the concrete component at time t under the current curing mode, ω(t) is the time-varying weighting coefficient at time t, and γ is the maximum surface temperature change rate. Let t be the theoretical core temperature of the concrete member under the current curing mode at time t. Let εt be the theoretical surface temperature of the concrete component under the current curing mode at time t, ε1 be the preset temperature difference homogenization efficiency, ε2 be the preset surface temperature stability efficiency, and Δt be the sampling time interval. Let t be the theoretical internal and external temperature difference of the concrete member under the current curing mode at time t. Let be the target internal and external temperature difference of the concrete component at time t under the current curing mode. Let be the theoretical surface temperature change rate of the concrete member at time t under the current curing mode. Let t be the rate of change of the target surface temperature of the concrete component under the current curing mode at time t.

[0083] In this embodiment, the calculation efficiency and accuracy of the comprehensive thermal stress risk value can be improved, providing accurate data for the subsequent determination of the target maintenance mode. Furthermore, the maintenance control target is directly related to the time-varying properties of the material, realizing the shift from traditional temperature index control to active stress and crack control based on the material damage mechanism.

[0084] After determining the comprehensive thermal stress risk value of the concrete component under each curing mode at the next moment, the curing mode with the smallest comprehensive thermal stress risk value among multiple curing modes can be identified as the target curing mode.

[0085] Optionally, the curing device may include a curing plate, multiple pipelines, and at least two media storage devices. The curing plate covers the surface of the concrete component. The curing plate may include a cavity and a first media inlet and a first media outlet communicating with the cavity. The cavity is a closed cavity. The media storage devices are used to store curing media. Each media storage device can only store one type of curing media. Each media storage device includes a second media inlet and a second media outlet.

[0086] Furthermore, the first inlet of the curing plate is connected to the second outlet of each media storage device via a pipeline, and the first outlet of the curing plate is connected to the second inlet of each media storage device via a pipeline, so as to connect the cavity of the curing plate with each media storage device. By injecting or discharging the curing medium into the cavity, the curing mode of the curing plate can be reversibly changed, thereby changing the overall thermal performance of the curing plate.

[0087] S250. Switch the current curing mode of the curing device to the target curing mode so that the curing device can use the curing medium corresponding to the target curing mode to cure the concrete component.

[0088] Specifically, it can detect the current media type inside the cavity, that is, the type of the current maintenance media inside the cavity, and determine whether the current media type is the same as the media type corresponding to the target maintenance mode.

[0089] When the current media type is different from the media type corresponding to the target maintenance mode, the first media outlet of the maintenance plate and the second media inlet of the media storage device corresponding to the current media type can be opened so that the current maintenance media inside the cavity flows into the media storage device corresponding to the current media type, and then the current maintenance media inside the cavity is discharged.

[0090] In response to the emptying of the current curing medium inside the cavity, the first outlet medium port of the curing plate and the second inlet medium port of the medium storage device corresponding to the current medium type are closed, while the first inlet medium port of the curing plate and the second outlet medium port of the medium storage device corresponding to the medium type of the target curing mode are opened, allowing the curing medium corresponding to the target curing mode to flow into the cavity. This switches the current curing mode of the curing device to the target curing mode. This improves computational efficiency, reduces implementation complexity, and thus improves the efficiency and accuracy of curing medium switching, thereby improving the efficiency and accuracy of curing mode switching.

[0091] When the current media type is the same as the media type corresponding to the target maintenance mode, there is no need to control the maintenance device to perform a switching operation.

[0092] Optionally, to optimize economics, the curing system can adopt a targeted intelligent curing strategy. This involves deploying curing boards and multiple temperature sensors in the most representative high-risk areas of thermal stress within the concrete structure, rather than covering the entire surface. For example, high-risk areas of thermal stress might be the cast-in-place joints / post-cast strips between concrete components, meaning covering all exposed surfaces of the cast-in-place section (such as the top and sides) to focus on controlling the temperature difference between new and old concrete and the overall surface cooling rate. Targeted deployment in high-risk areas of the concrete structure achieves maximum crack prevention benefits with minimal investment, offering strong versatility and high economic efficiency.

[0093] The technical solution of this application embodiment predicts the theoretical temperature field data of the concrete component at the next moment based on the temperature field data of the previous moment and the temperature field data of the current moment, and determines the theoretical temperature field characteristic data of the concrete component at the next moment based on the theoretical temperature field data of the next moment. Then, it uses the preset medium efficiency factor of each curing mode to correct the theoretical temperature field characteristic data of the next moment, obtaining the target temperature field characteristic data of the concrete component at the next moment under the corresponding curing mode, which can improve the prediction efficiency and accuracy of the target temperature field characteristic data of the next moment. Next, based on the target temperature field characteristic data corresponding to each curing mode, it determines the comprehensive thermal stress risk value of the concrete component at the next moment under the corresponding curing mode, and based on the comprehensive thermal stress risk value, it selects from multiple... By identifying the target curing mode within a curing mode, the optimal curing mode for the next moment can be determined. The current curing mode of the curing device is then switched to the target curing mode, allowing the device to utilize the corresponding curing medium to cure the concrete component. This enables the same curing device to reversibly and rapidly switch between multiple curing modes and adapt to the thermal management needs (i.e., curing requirements) of the concrete component at the next moment. It also represents a leap from "passive response" to "proactive optimization control," making temperature control more scientific and precise, thereby improving the temperature control accuracy of the curing device. Furthermore, it can accurately match the dynamic thermal management needs of the concrete component at different hydration stages, thus improving the precision of concrete curing and reducing the risk of cracking in the concrete component.
