Description

Technical Field

[0001] This application relates to the field of concrete construction technology, and in particular to control devices, control systems and control methods. Background Technology

[0002] Dam concrete construction is a crucial step in water conservancy engineering, and its curing quality directly affects the overall safety and long-term durability of the project. When constructing dam concrete in cold regions, the unique harsh climatic conditions, including low temperatures, dryness, and large diurnal temperature variations, pose extremely demanding challenges to concrete curing. Low temperatures significantly slow down the cement hydration reaction rate, resulting in slow concrete strength development and failure to meet design requirements. More seriously, when the ambient temperature drops below freezing, the free water inside the concrete freezes and expands, damaging the internal microporous structure and reducing the concrete's density and final strength. Furthermore, excessive temperature differences between the inside and outside of the concrete can easily trigger temperature stress cracks, while a dry environment accelerates surface moisture evaporation, not only affecting the full hydration reaction but also leading to drying shrinkage cracks. All of these factors severely compromise the concrete's durability and structural integrity.

[0003] Currently, the commonly used methods for concrete curing in cold regions include segmented insulation blanket covering, water curing, and traditional heated shed methods. However, the insulation effect is not ideal, which affects the final curing quality of the concrete. Summary of the Invention

[0004] Therefore, it is necessary to provide a control device, control system, and control method to address the problem that the current curing methods used for concrete curing in cold regions do not have ideal heat preservation effects.

[0019] And / or, a plurality of the temperature control components are disposed on the support frame around the opening interval, and a plurality of the humidity control components are disposed on the support frame around the opening interval, and are arranged alternately with the plurality of temperature control components.

[0020] In one embodiment, the carrier component includes:

[0021] Multiple support plates, which enclose the cavity;

[0022] The fastening components include multiple columns, multiple beams, and multiple diagonal braces, which are located outside the support plates to securely connect the multiple support plates.

[0023] Secondly, embodiments of this application provide a control system, including the control device described in the first aspect; and...

[0024] The main control unit is communicatively connected to both the temperature control component and the humidity control component.

[0025] Thirdly, embodiments of this application provide a control method applied to the control system of the second aspect; the control method includes:

[0026] The system acquires real-time internal parameters of the concrete, parameters inside the control device, and environmental parameters of the external environment, and integrates the internal parameters, parameters inside the control device, and environmental parameters to form multi-source data; wherein the internal parameters, parameters inside the control device, and environmental parameters include at least temperature and humidity information;

[0027] The curing information of the concrete is obtained, and the curing process is divided into multiple control stages based on the curing information, each of which has a different target temperature and humidity range.

[0028] When the parameters inside the greenhouse are lower than the lower limit of the target temperature and humidity range in the current control phase, the multi-source data, future predicted environmental parameters, and future predicted internal parameters are acquired and input into a preset heat conduction model to obtain the target parameters inside the greenhouse for a predetermined time step in the future.

[0029] The target greenhouse parameters are compared with the target temperature and humidity range of the current control stage. If the target greenhouse parameters are lower than the lower limit of the target temperature and humidity range, the corresponding compensation temperature difference and / or compensation humidity difference are calculated, and the heating power corresponding to the compensation temperature difference and the humidification power corresponding to the compensation humidity difference are generated.

[0030] The operation of the heating unit is controlled based on the heating power, and the operation of the humidification unit is controlled based on the humidification power, so that the parameters inside the greenhouse are maintained within the target temperature and humidity range.

[0041] The aforementioned control device, system, and method, through the cooperation of guide rails on the bearing component and moving wheels at the bottom of the support component, enable the support component and covering component to move and position flexibly and quickly along the silo surface. Furthermore, the modular design of the covering component allows for rapid assembly, disassembly, and turnover of the control device, significantly reducing the manpower and time required for the construction and dismantling of traditional heated sheds, thus lowering construction costs. Additionally, the distributed temperature and humidity sensors, along with corresponding control units, form a closed-loop control system that can respond in real-time to changes in the chamber environment. This system utilizes evenly distributed warm air blowers and sprayers to implement control measures, effectively overcoming the uneven temperature distribution inherent in traditional heated sheds. This provides a stable and uniform microclimate for concrete curing, offering reliable equipment support for high-quality construction of dam concrete in cold regions. Attached Figure Description

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0057] As mentioned in the background section, common engineering methods for concrete curing in cold regions include segmented insulation blankets, continuous water curing, and traditional heated sheds. Among these, segmented insulation blankets, while easy to install, have limited insulation effects and cannot be temperature-adjusted. They are ill-suited to the complex conditions of large diurnal temperature differences in cold regions and cannot effectively maintain the stability of the internal temperature of the concrete, resulting in less than ideal insulation performance.

[0058] Furthermore, the water curing method is not effective in low-temperature environments because low temperatures cause the curing water temperature to drop rapidly, and may even cause the concrete surface to freeze. This not only fails to provide the necessary temperature conditions for concrete hydration, but the ice expansion effect will also exacerbate the risk of cracking on the concrete surface.

[0059] Furthermore, while traditional greenhouses can create insulation to some extent, their construction and dismantling are cumbersome, requiring significant manpower and time, resulting in low construction efficiency and inconvenience for reuse. More importantly, the temperature distribution within traditional greenhouses is extremely uneven, with obvious temperature gradients. Manual control can usually only manage a general temperature range based on a few measuring points, easily leading to localized hot and cold spots that are either too high or too low. This makes it impossible to achieve precise control over the concrete curing environment, thus affecting the uniformity of the final curing quality of the concrete.

[0060] To address the aforementioned problems, this application provides a control device, control system, and control method. Through the cooperation of guide rails on the supporting component and moving wheels at the bottom of the supporting component, the supporting component and the covering component can move and position flexibly and quickly along the surface of the shed. Furthermore, the modular design of the covering component enables rapid assembly, disassembly, and turnover of the control device, significantly reducing the manpower and time required for the construction and dismantling of traditional heated sheds, thus lowering construction costs. Additionally, a closed-loop control system is formed by distributed temperature and humidity sensors and corresponding control units, enabling real-time response to changes in the internal environment. Control is achieved through uniformly distributed warm air blowers and sprayers, effectively overcoming the uneven temperature distribution inherent in traditional heated sheds. This provides a stable and uniform microclimate for concrete curing, offering reliable equipment support for high-quality construction of dam concrete in cold regions.

[0061] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a control device provided according to some embodiments of this application. Figure 2 This is a cross-sectional structural schematic diagram of a control device provided according to some embodiments of this application. The control device provided in this application embodiment is mainly used for the curing of concrete 400 on the surface of a dam in cold regions. The control device may include a load-bearing component 100, a support component 200, a covering component 300, a temperature control component, and a humidity control component.

[0062] The supporting component 100 has a cavity 101 for filling with concrete 400; the supporting component 100 has an opening communicating with the cavity 101, and a supporting surface surrounding the opening, with at least a portion of the supporting surface having a guide rail 120; a supporting component 200 is disposed on the supporting surface of the supporting component 100, and the supporting component 200 includes a support frame 210 and a moving wheel 220, the moving wheel 220 being adapted to be installed on the guide rail 120, and the support frame 210 being disposed on the side of the moving wheel 220 away from the guide rail 120; a covering component 300 is disposed on the support frame 210, and the covering component 300 is used to cover the opening; the covering component 300 and the support frame 210 together form a chamber 201 communicating with the cavity 101; a temperature control component is disposed in the chamber 201, and the temperature control component includes a lighting unit, a heating unit, a temperature sensor, and a temperature control unit; a humidity control component is disposed in the chamber 201, and the humidity control component includes a humidification unit, a humidity sensor, and a humidity control unit.

[0063] It is understood that the bearing component 100 can be understood as a structure composed of multiple support plates, forming a cavity 101 structure adapted to the dam deck surface, which can be used to fill and pour concrete 400. The top of the bearing component 100 has a bearing surface, and the bearing surface is arranged around the opening communicating with the cavity 101, which allows the bucket to enter and unload the concrete 400.

[0064] At least two guide rails 120 or tracks are arranged in parallel on the bearing surface. For example, the guide rails 120 are fixedly installed on the bearing surface of the bearing component 100 by pre-embedded anchor bolts to ensure a stable installation foundation. The guide rails 120 can be made of high-strength steel to have good load-bearing capacity and deformation resistance, so as to bear the weight and moving load of subsequent components.

[0065] The movable wheels 220 of the support assembly 200 can be fitted onto the guide rail 120, specifically meaning that the grooves of the movable wheels 220 match the cross-sectional shape of the guide rail 120 to ensure smooth rolling. For example, the movable wheels 220 are equipped with self-lubricating bearings to reduce frictional resistance and improve movement efficiency. Alternatively, a braking device, such as a friction plate brake, can be integrated into the movable wheels 220 or the group of movable wheels 220. Once the support frame 210 is in place, the braking device locks the wheel in place to prevent accidental movement.

[0066] The support frame 210 is fixedly installed above the movable wheel 220. The support frame 210 is usually designed as an arched bracket. Each arched bracket can be connected to a movable wheel 220, or multiple arched brackets can be connected to the same movable wheel 220. The movement of the movable wheel 220 drives multiple support frames 210 to retract or expand, thereby covering or exposing the cavity 101.

[0067] Meanwhile, a traction device can be connected to the mobile wheel 220 via a steel wire rope to provide mobility. This configuration enables modular and reusable use of the control device, which helps improve construction efficiency. Of course, the driving method of the mobile wheel 220 is not limited to traction; it can also be designed as an electrically driven wheel.

[0068] In this embodiment, the covering component 300 may include multiple pieces of insulating tarpaulin. These pieces are spliced ​​together and then placed over the support frame 210. They can be fixed to the support frame 210 using detachable screws, achieving full coverage of the support frame 210. The covering component 300, together with the support frame 210, forms a relatively sealed curing chamber 201 that communicates with the lower cavity 101; this can also be called an insulating shed. The covering component 300 serves as the insulating and sealing part of the entire control device, and, combined with the movable design of the support frame 210, addresses the issue of coordinating construction material feeding and insulation. Furthermore, the arched design of the support frame 210 facilitates the sliding of snow from the top, preventing snow accumulation from collapsing the structure.

[0069] It should be noted that the aforementioned covering component 300 can also be a composite insulation felt, aluminum foil-coated foam roll, etc., as long as it can meet the requirements of low heat transfer coefficient, waterproof, windproof and durable. No specific restrictions are imposed here.

[0070] In this embodiment, the temperature control component is mainly located in the chamber 201 near the support frame 210. This avoids affecting the filling of the concrete 400 below and facilitates installation on the support frame 210. The lighting unit can be a detachable explosion-proof lamp to provide illumination for work within the chamber 201. The heating unit can be a warm air blower; multiple units can be installed and staggered on the support frame 210 to ensure uniform downward diffusion of hot air and prevent localized overheating. The temperature sensors can be high-precision sensors, distributed across different locations within the chamber 201 for comprehensive monitoring of the internal temperature. The temperature control unit, also known as the temperature controller, can be installed in a waterproof electrical control box on the inner wall of the chamber 201.

[0071] The temperature sensor and temperature control unit are electrically connected via signal lines, and the temperature control unit and heating unit are electrically connected via cables. The operation process can be as follows: the temperature sensor collects the temperature signal inside the chamber 201 in real time and sends it to the temperature control unit; the temperature control unit compares the received temperature value with the preset target temperature range; if the measured temperature is lower than the target lower limit, the temperature control unit sends a start command and power adjustment signal to the heater, and the heater starts to work to increase the temperature inside the chamber until the temperature returns to the set range.

[0072] Similarly, the humidity control component in this embodiment can also be installed on the support frame 210. The humidification unit can be a sprayer, and multiple sprayers can be arranged alternately on both sides or the top of the chamber 201 to form a uniform water mist. Humidity sensors can be distributed within the chamber 201 to monitor ambient humidity. The humidity control unit, also known as the humidity controller, can be integrated with the temperature control unit in the same electrical control box. Its operating principle is similar to that of the temperature control component: the humidity sensor sends a humidity signal to the humidity control unit; the humidity control unit compares it with a preset target humidity range; if the humidity is too low, the control unit activates the sprayer to humidify until the required humidity is reached.

[0073] In summary, the control device provided in this application embodiment, through the cooperation of the guide rail 120 on the bearing component 100 and the moving wheels 220 at the bottom of the support component 200, enables the support component 200 and the covering component 300 to move and position flexibly and quickly along the surface of the silo. Furthermore, combined with the modular design of the covering component 300, the control device can be quickly disassembled and reused, greatly reducing the manpower and time required for the construction and dismantling of traditional heated sheds, and lowering construction costs. Moreover, by forming a closed-loop control system with distributed temperature and humidity sensors and corresponding control units, the system can respond in real time to changes in the environment within the chamber 201, and perform control through uniformly arranged warm air blowers and sprayers, thereby effectively overcoming the uneven temperature distribution defects of traditional heated sheds, providing a stable and uniform microclimate for the curing of concrete 400, and providing reliable equipment support for high-quality construction of dam concrete 400 in cold regions.

[0074] Below, we will combine the appendix Figure 1 and attached Figure 2 The specific structure of the control device provided in the embodiments of this application will be described in detail.

[0075] See Figure 1 In some embodiments, the control device includes multiple support components 200, each support component 200 including multiple support frames 210 and multiple movable wheels 220; the movable wheels 220 are located at the ends of the support frames 210 near the bearing components 100; the movable wheels 220 are engaged in the guide rail 120 and slide along the guide rail 120; the movable wheels 220 are used to drive the support frames 210 to move, so as to form a feed port between two adjacent support components 200.

[0076] Specifically, by precisely locking the movable wheel 220 within the guide rail 120 on the bearing surface, the movable wheel 220 can slide smoothly along the guide rail 120 while also limiting its position, thus ensuring a stable connection between the support component 200 and the bearing component 100 in harsh environments such as strong winds.

[0077] In this embodiment, multiple sets of support components 200 are provided on the support component 200. By controlling the movement of a specific support component 200, an openable and closable feed port can be dynamically formed between two adjacent support components 200. For example, when feeding is required, a set of support frames 210 is moved away along the track by a traction device, forming an open channel between it and the adjacent fixed support frame 210, through which the concrete 400 bucket can be vertically entered for unloading. After unloading is completed, the moved support frame 210 is reset, the feed port is closed, and the complete insulation chamber 201 is restored.

[0078] The above design of this embodiment enables a precise feeding mode that allows for opening holes as needed and closing them immediately upon use, and can minimize the loss of heat and humidity inside the curing chamber 201, which is beneficial for reducing energy consumption.

[0079] See Figure 2 In some embodiments, the support frame 210 is arched. Specifically, the arched top facilitates the natural sliding off of snow and rainwater, effectively preventing snow loads from collapsing the structure or water from seeping in, thus enhancing the safety and durability of the device in cold and snowy environments. Simultaneously, the arched structure provides greater clearance for the construction space below, facilitating equipment and personnel operation.

[0080] In one example, the control device also includes a drive mechanism connected to the moving wheel 220 via a drive bar. Specifically, the drive mechanism can be an electric hoist or a servo motor, and the drive bar can be a wire rope, chain, or toothed belt. Connecting the drive mechanism and the moving wheel 220 via the drive bar provides power for the movement of the support frame 210, replacing inefficient manual pushing and improving automation level and movement efficiency.

[0081] In one example, the control device also includes a braking mechanism connected to the moving wheel 220. Specifically, the braking mechanism can be a friction plate brake integrated into the moving wheel 220, and can be mechanically connected to the moving wheel 220. Of course, the braking mechanism can also be other forms, which are not limited here. When the support frame 210 moves to the target work position, activating the braking mechanism can firmly lock the moving wheel 220, preventing the device from being accidentally displaced under wind, slight slope, or equipment vibration, thus ensuring the absolute stability and safety of the entire curing shed during construction and maintenance.

[0082] In one example, the control device also includes multiple camera units, with at least one camera unit at each feed inlet. Specifically, the camera units can be waterproof and dustproof industrial cameras that can capture real-time images of the lowering of the hoist, the unloading of concrete, and operations within the silo, and transmit these images to the control room or a remote terminal. This setup allows operators to monitor the feeding process in real time, accurately determine the position of the hoist, and avoid collisions.

[0083] In some embodiments, the covering component 300 includes multiple insulating tarpaulins, which are fixedly connected to the support frame 210.

[0084] Understandably, the thermal insulation tarpaulin can be fixedly connected to the inner and outer sides of the support frame 210 through detachable connection methods, such as rivets, special buckles or high-strength straps, to achieve all-round wrapping of the support frame 210 structure.

[0085] In one example, multiple temperature control components are spaced around the opening on the support frame 210, and multiple humidity control components are spaced around the opening on the support frame 210, and are arranged alternately with the multiple temperature control components.

[0086] Specifically, multiple heaters and temperature sensors, as well as multiple sprayers and humidity sensors, are arranged on the support frame 210, surrounding the feed inlet or evenly distributed throughout the chamber 201. For example, the heaters and temperature sensors, as well as the sprayers and humidity sensors, are arranged in a staggered pattern. In this embodiment, mounting the temperature and humidity control components on the support frame 210 avoids interference with the pouring and vibration operations below, and facilitates pipeline installation and maintenance. The uniform and staggered arrangement of the temperature and humidity control components creates a uniform and stable temperature and humidity field within the curing chamber 201, effectively solving the problems of localized overheating, overhumidification, or excessive cold and dryness in traditional heated sheds, ensuring the uniformity of concrete curing quality.

[0087] In some embodiments, the support assembly 100 includes a plurality of support plates, which enclose a cavity 101; the fastening component 500 includes a plurality of columns, a plurality of beams and a plurality of diagonal braces, which are disposed outside the support plates to fasten the plurality of support plates.

[0088] Understandably, the support plate can be understood as a large steel formwork or support plate. Multiple support plates are assembled together by connectors to form a cavity 101 for filling concrete 400. To enhance the rigidity and stability of the entire storage structure, fastening components 500 are also provided. These fastening components 500 include multiple columns, beams, and diagonal braces, which can be connected by welding or high-strength bolts to form a stable spatial truss structure. They are located around the support plates to clamp and fix the multiple support plates from the outside.

[0089] The aforementioned structural design makes the load-bearing component 100 itself a high-strength, high-stability modular unit, effectively resisting the lateral pressure during concrete pouring, preventing formwork displacement and bulging, and ensuring the accuracy of the poured shape. This modular design also facilitates rapid transfer and reuse between different formwork sections, significantly reducing material waste and construction costs compared to traditional disposable formwork.

[0090] Based on the same concept, this application also provides a control system, including the control device of the above embodiment; and a main control unit, which is communicatively connected to the temperature control component and the humidity control component respectively.

[0091] Understandably, the main control unit can be a PLC (Programmable Logic Controller), an industrial computer, or an embedded computing system, typically installed in a waterproof and dustproof control cabinet. The main control unit establishes bidirectional communication connections with the temperature control unit, temperature sensor, and heating unit in the temperature control component, and the humidity control unit, humidity sensor, and humidification unit in the humidity control component, via wired (e.g., CAN, Profibus) or wireless (e.g., 4G / 5G, Wi-Fi, LoRa) communication methods.

[0092] In this embodiment, the central control unit is configured to continuously receive real-time monitoring data from temperature and humidity sensors distributed in various locations. Simultaneously, it acquires external environmental data (solar radiation, wind speed, external temperature and humidity) transmitted from the integrated on-site weather station via an interface, as well as internal temperature data of the concrete 400 provided by the distributed fiber optic temperature measurement system. As a data fusion center, the central control unit integrates and calibrates the aforementioned multi-source, heterogeneous information to form a comprehensive and accurate perception of the system's current state.

[0093] Simultaneously, the main control unit pre-stores or runs dynamic prediction and decision-making models in real time, such as physical models based on heat and mass conduction or data-driven AI models. Based on fused real-time data, it executes the following algorithms: environmental prediction, combining numerical weather prediction to predict the trend of external environmental changes over a future period; and state prediction, using the predicted external environment and the current internal temperature of the concrete 400 to predict the future temperature and humidity state within the curing chamber 201 through a built-in model. When the prediction results deviate from the preset curing curves for each stage, such as when the temperature will fall below the lower limit of the stage, the main control unit will not wait for the deviation to occur but will initiate the decision-making process in advance. Among these, a multi-objective optimization algorithm is used to calculate the optimal heating power and humidification power with the goal of minimizing operating costs while meeting the curing process requirements.

[0094] The central control unit sends the calculated optimal power command to the execution units of the temperature and humidity control components, namely the heater and the sprayer. The corresponding devices then precisely adjust their output according to the command, achieving feedforward-feedback composite control of the maintenance environment. For example, before a cold snap, the system can preemptively raise the greenhouse temperature to offset anticipated heat loss, rather than waiting for the temperature to drop before taking action, thus achieving truly precise and predictive control.

[0095] In addition, the main control unit usually integrates a remote communication module. Construction managers can access the operation interface provided by the main control unit through terminal devices such as mobile phones, tablets or remote computers. Through this interface, they can remotely view all sensor data, equipment operating status, alarm information in real time, and perform parameter settings (such as modifying the target value of the maintenance stage), mode switching, and remote start and stop operations.

[0096] The multi-objective optimization algorithm built into the main control unit provided in this implementation can dynamically seek the lowest energy consumption operating strategy while ensuring the rigid requirements of the 400mm concrete curing process. Furthermore, by accurately calculating the required power, it avoids ineffective or excessive operation of the equipment, thereby minimizing the operating costs of insulation, heating, and humidity control while ensuring the highest curing quality, achieving the goal of green and energy-saving construction.

[0097] Based on the same concept, this application also provides a control method applied to the control system described above; the control method includes:

[0098] Step S101: Acquire the internal parameters of the concrete 400, the parameters inside the control device, and the environmental parameters of the external environment in real time, and fuse the internal parameters, the parameters inside the control device, and the environmental parameters to form multi-source data; wherein, the internal parameters, the parameters inside the control device, and the environmental parameters include at least temperature information and humidity information;

[0099] Step S102: Obtain the curing information of concrete 400. Based on the curing information, divide the curing process into multiple control stages, each control stage having a different target temperature and humidity range.

[0100] Step S103: When the parameters inside the greenhouse are lower than the lower limit of the target temperature and humidity range of the current control stage, acquire multi-source data, future predicted environmental parameters and future predicted internal parameters, and input them into the preset heat conduction model to obtain the target parameters inside the greenhouse for the future predetermined time step.

[0101] Step S104: Compare the target greenhouse parameters with the target temperature and humidity range of the current control stage. If the target greenhouse parameters are lower than the lower limit of the target temperature and humidity range, calculate the corresponding compensation temperature difference and / or compensation humidity difference, and generate the heating power corresponding to the compensation temperature difference and the humidification power corresponding to the compensation humidity difference.

[0102] Step S105: Control the operation of the heating unit based on the heating power and control the operation of the humidification unit based on the humidification power to maintain the parameters inside the greenhouse within the target temperature and humidity range.

[0103] It is understood that in step S101, the main control unit in the above embodiment collects the following parameters in real time through various sensors integrated in the control device, including the internal temperature of the concrete, obtained through distributed optical fibers embedded in the concrete. Data, including indoor air temperature, is obtained through high-precision temperature and humidity sensors distributed within the curing chamber. and the humidity of the air inside the shed External environmental parameters, including at least external temperature, are obtained through an integrated weather station located outside the station. External humidity In some examples, environmental parameters also include solar radiation information. Wind speed information Specifically, this includes solar radiation intensity and wind speed.

[0104] In some embodiments, step S101 further includes step S1011, which uses a Kalman filter to fuse the internal parameters, indoor parameters, and environmental parameters. Specifically, after obtaining all the above parameters, the main control unit can use a data fusion algorithm such as a Kalman filter to fuse the multi-source, potentially noisy, real-time data. This step can filter out interference and obtain a smoother, more realistic estimate of the system's current state, laying the foundation for subsequent accurate predictions.

[0105] In step S102, concrete curing information (such as concrete grade, mix proportion, design strength, etc.) is obtained from the storage unit or input by the operator. Based on the hydration heat release characteristics of large-volume concrete, the system automatically divides the entire curing process into multiple control stages with different control objectives. In some embodiments, the curing process includes: a first control stage, wherein the temperature is 10℃-15℃ and the humidity is 70%-90%; a second control stage, wherein the temperature is 15℃-20℃ and the humidity is 70%-90%; and a third control stage, wherein the temperature is 5℃-10℃ and the humidity is 70%-90%.

[0106] Specifically, the first control phase is from 0 to 72 hours, corresponding to the concentrated release period of hydration heat in concrete, requiring control of the internal temperature rise rate. The second control phase is from 72 hours to 14 days, guiding the concrete to cool slowly after the temperature peak. The third control phase is from 14 days onwards, further stabilizing the core temperature of the concrete to bring it closer to ambient temperature. The above settings in this embodiment achieve refined and dynamic curing that matches the characteristics of concrete materials; and different temperature control ranges precisely correspond to the strength and crack prevention requirements of concrete at different ages.

[0107] In step S103, when the current greenhouse parameter is detected to be lower than (or will be lower than) the target lower limit of the current control stage, the prediction process is initiated.

[0108] In one example, step S103 further includes: step S1031, setting up distributed optical fibers inside the concrete and collecting data from the distributed optical fibers in real time as internal parameters of the concrete. And predict future time steps based on internal parameters. The internal temperature and humidity of the concrete were used as parameters for future prediction of internal properties. .

[0109] Specifically, the system is based on historical and current data of the internal temperature of concrete collected in real time using distributed optical fibers. Using a built-in concrete thermal model, the internal temperature of concrete at a predetermined time step is predicted, i.e., the predicted internal parameters. .

[0110] In one example, step S103 further includes: step S1032, obtaining weather forecast information based on real-time collected environmental parameters of the external environment to obtain a predetermined future time step. Future predicted environmental parameters , , , .

[0111] Specifically, the system predicts external environmental parameters at the same time step in the future based on real-time collected environmental parameters and combined with numerical weather forecast information obtained from the Internet, including... , , , These are also known as future environmental parameters.

[0112] Subsequently, the fused multi-source real-time data, future predicted environmental parameters, and future predicted internal parameters are input together into the preset heat conduction and mass conduction coupling model. In this process, the target greenhouse parameters for the predetermined future time step are calculated, i.e., the predicted greenhouse temperature. Humidity inside the greenhouse .

[0113] This embodiment uses model prediction to predict future environmental changes and their impact on the greenhouse, thereby enabling proactive regulation in advance and reducing the impact of environmental disturbances, thus ensuring a stable maintenance environment.

[0114] In step S104, the target greenhouse parameters predicted in the above steps are compared with the target temperature and humidity range for the current stage. If the predicted greenhouse temperature is lower than the lower limit of the target temperature, Then calculate the temperature difference that needs to be compensated. If the predicted humidity inside the greenhouse is lower than the target humidity lower limit Then calculate the moisture difference that needs to be compensated. .

[0115] Subsequently, based on the principles of energy conservation and mass conservation, corresponding control commands are generated: Heating power: Where c is the specific heat capacity of air, m is the mass of air, and η is the heating efficiency; humidification power: Where L is the latent heat of vaporization of water, and η1 is the humidification efficiency. The main control unit converts the calculated optimal heating power and humidification power into control signals, which are sent to the heater and sprayer respectively, thereby controlling them to operate at precise power. This embodiment ensures the accuracy of energy and water supply by converting the required heating or humidification into quantitative power commands, avoiding ineffective equipment operation or over-regulation, and helping to minimize operating costs.

[0116] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0117] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
