Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and in particular to an intelligent concrete circulating spraying curing control system and method. Background Art

[0002] Concrete cycle spray curing control is a concrete curing technology used to keep the concrete surface moist to promote early strength development and long-term durability of concrete. This technology controls the spraying water or other curing media through an automated system to ensure that the concrete does not lose water prematurely in the early stages and maintains appropriate moisture throughout the curing period.

[0003] In the actual curing process of concrete, after receiving the sprayed water, the concrete will form a solid bonding system through hydration reaction. Considering that too large a spraying volume will cause the concrete surface hydration to be too frequent and prolong the cement hydration time; and too small a spraying volume will cause the concrete to be unable to form a solid gel system; that is, relative to the spraying requirements of concrete, both too large and too small a spraying volume will affect the strength development of concrete. Therefore, it is necessary to control the spraying water volume that meets the concrete curing requirements for concrete curing.

[0004] The prior art usually determines the total amount of spray water that meets the concrete curing requirements based on the total content of hydration products formed when the concrete has different spray water outputs, thereby controlling the spray system to perform cyclic spray curing on the concrete with a fixed total amount of spray water that meets the concrete curing requirements during each cyclic spray curing. In order to maintain the wetness of the concrete, the fixed total amount of spray water is sprayed evenly and multiple times during the same cyclic spray curing process, so that the concrete can maintain a certain wetness during the entire cyclic spray curing process.

[0005] However, as time goes by, the tolerance of concrete to the sprayed water will change, and environmental factors will also interfere with the intensity and progress of the hydration reaction, so the spray water volume corresponding to the concrete curing needs will change; therefore, when the existing technology uses a fixed total amount of spray water to perform cyclic spray curing on concrete, excessive or insufficient spraying volume will affect the strength development of concrete, resulting in poor effect of concrete cyclic spray curing. Summary of the invention

[0042] This application has the following beneficial effects:

[0043] For concrete, when the spraying water volume changes, the greater the change in the corresponding total content of hydration products with the same change trend, the greater the influence of the spraying water volume on the total content of hydration products, that is, the stronger the tolerance of concrete to spraying water, the greater the corresponding spraying tolerance. Therefore, the spraying tolerance factor of concrete is determined based on this characteristic.

[0044] Environmental factors can also affect the hydration reaction process. For example, temperature can affect the evaporation rate of water, so it is necessary to determine the environmental interference factor to determine a more accurate real-time spray water output; the impact of environmental factors can be characterized by the hydration reaction intensity or rate, so the hydration reaction intensity coefficient is determined according to the change in the content of hydration products produced by the concrete, and further the interference or influence of environmental factors on the hydration reaction can be determined through the influence of the hydration reaction intensity coefficient on the total content of hydration products; therefore, the degree of interference is quantified according to the similarity in the trend of the hydration reaction intensity coefficient and the total content of hydration products in the time sequence, and the environmental interference factor that characterizes the influence of environmental factors on the hydration reaction is determined.

[0045] Further considering that the single spray curing process is sprayed evenly multiple times, the water output of each spray is the same, so changing the spray frequency will also affect the total amount of spray water in the single spray curing process; however, the existence of spray frequency also means the existence of spray intervals. When the spray interval is too large, the concrete cannot be replenished with water in time, and the strength of the concrete will deteriorate quickly, and the effect of deterioration on the strength of the concrete is irreversible only through spraying; therefore, the more significant the concrete deterioration in the spray curing process at the current moment, the more it is necessary to reduce the spray interval, thereby indirectly affecting the spray water output; therefore, the degradation accumulation factor obtained according to the changing trend of the significant concrete degradation will also affect the real-time spray water output control. Finally, the spray tolerance factor, environmental interference factor and degradation accumulation factor are combined, and the real-time spray water output is more accurately controlled according to the obtained spray curing adjustment coefficient, so that the effect of concrete cyclic spray curing is better.

[0053] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of an intelligent concrete circulating spraying maintenance control system and method proposed according to the present invention, in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment, and the specific features, structures or characteristics in one or more embodiments may be combined in any suitable form. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0054] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0055] The specific scheme of an intelligent concrete circulation spraying maintenance control system and method provided by the present invention is described in detail below with reference to the accompanying drawings.

[0056] This application embodiment provides an intelligent concrete cycle spraying maintenance control method, please refer to Figure 1 , which shows a flow chart of an intelligent concrete cycle spraying curing control method provided by an embodiment of the present invention, the method comprising:

[0057] Step S101: collecting the total amount of spray water corresponding to each spray curing process and the hydration product content of the concrete at each sampling time in each spray curing process; and calculating the total content of the hydration product of the concrete after each spray curing.

[0058] Concrete hydration is an important stage in the curing process. The main component of cement, mature cement minerals, undergoes hydration reaction in the presence of water to generate hydration products such as cementitious substances, which then fill the voids in the cement mortar in the concrete and form a solid bonding system, thereby giving the concrete mechanical strength and durability. Considering that in the subsequent analysis of the spray tolerance factor, it is necessary to determine it based on the correlation between the total amount of spray water and the total content of hydration products during the spray curing process, the total amount of spray water corresponding to each spray curing process is collected and the total content of hydration products of the concrete after each spray curing is counted. The acquisition process of the environmental interference factor needs to be combined with the temporal changes in the content of hydration products, so the content of hydration products of the concrete at each sampling time during each spray curing process is collected.

[0059] The circulating spray curing system will spray the concrete periodically during spray curing to fully hydrate the concrete, that is, a single spray curing process includes multiple sprayings. Therefore, in order to accurately control the total amount of spray water, the circulating spray curing system is controlled to spray periodically with the same spray water volume, and the time of all spray curing processes is the same. Then the total spray water volume can be obtained through the spraying frequency of each spray curing process.

[0060] In a specific implementation of the embodiment of the present invention, the corresponding total amount of spray water is determined by the circulating spray curing equipment according to the water output of each spray and the spray frequency; that is, the product of the spray frequency and the water output of each spray is used as the total amount of spray water corresponding to each spray curing process. In a specific implementation of the embodiment of the present invention, the infrared spectrum of the concrete at each sampling time in each spray curing process is collected by the infrared spectrum device installed on the circulating spray curing equipment; and the hydration product content of the concrete at each sampling time in each spray curing process is determined according to the functional group components in the infrared spectrum, and the corresponding total content of hydration products is the hydration product content of the concrete in the infrared spectrum of the concrete after the spray curing process is completed; and the time interval between two adjacent sampling times is set to 5 minutes, which can be adjusted according to the specific implementation environment; in addition, in order to make the real-time spray water output control more accurate, the 50 spray curing processes closest to the current time are used as all the spray curing processes analyzed by the embodiment of the present invention; the implementer can adjust the number of spray curing processes according to the specific implementation environment.

[0061] Step S102: Determine the spray tolerance factor of the concrete according to the correlation between the total amount of spray water and the total content of hydration products corresponding to each spray curing process and the change in the total amount of spray water.

[0062] For concrete, when the spray water output changes, the greater the change in the corresponding total content of hydration products with the same trend, the greater the influence of the spray water output on the total content of hydration products, that is, the stronger the tolerance of concrete to spray water, the greater the corresponding spray tolerance, and the smaller the water demand of concrete. Therefore, the spray tolerance factor of concrete is determined according to the correlation between the total amount of spray water and the total content of hydration products corresponding to each spray curing process and the change in the total amount of spray water, and the spray water output of concrete is controlled according to the spray tolerance factor.

[0063] Step S103: Determine the hydration reaction intensity coefficient of the concrete corresponding to each spraying curing according to the time series change of the hydration product content of the concrete during each spraying curing process; determine the environmental interference factor of the concrete according to the trend similarity between all the hydration reaction intensity coefficients and the total content of all the hydration products in the time series.

[0064] Environmental factors can also affect the hydration reaction process. For example, temperature can affect the evaporation rate of water, so it is necessary to determine the environmental interference factor to determine a more accurate real-time spray water output; the impact of environmental factors can be characterized by the intensity or rate of the hydration reaction, so the hydration reaction intensity coefficient is determined according to the change in the content of hydration products produced by the concrete, and further the interference or impact of environmental factors on the hydration reaction can be determined through the influence of the hydration reaction intensity coefficient on the total content of hydration products; therefore, the degree of interference is quantified according to the similarity in the trend of the hydration reaction intensity coefficient and the total content of hydration products in time sequence, and the environmental interference factor that characterizes the impact of environmental factors on the hydration reaction is determined; the larger the environmental interference factor, the greater the impact of the environment on the total content of hydration products, so the water demand of concrete will also be greater.

[0065] Step S104: Determine the degradation accumulation factor of the concrete at the current moment according to the changing trend of the significant concrete degradation during the spraying curing process corresponding to the current moment; determine the spraying curing adjustment coefficient corresponding to the current moment according to the spraying tolerance factor, the environmental interference factor and the degradation accumulation factor; and perform real-time spraying water output control according to the spraying curing adjustment coefficient.

[0066] The single spray curing process is to spray evenly multiple times, and the water output of each spray is the same, so changing the spray frequency will also affect the total amount of spray water output in the single spray curing process; however, the existence of a spray frequency also means the existence of a spray interval. When the spray interval is too large, the concrete cannot be replenished with water in time, and the strength of the concrete will deteriorate quickly, and the effect of the deterioration on the strength of the concrete is irreversible only by spraying; therefore, the more significant the concrete deterioration in the spray curing process corresponding to the current moment, the more it is necessary to reduce the spray interval, thereby indirectly increasing the demand for spray water output; therefore, the larger the degradation accumulation factor obtained according to the changing trend of the significant deterioration of the concrete, the greater the water demand of the concrete; further, according to the relationship between the spray tolerance factor, the environmental interference factor, the degradation accumulation factor and the water demand of the concrete, the spray curing adjustment coefficient is obtained to comprehensively characterize the adjustment parameters of the concrete water demand corresponding to the current moment, so as to perform more accurate real-time spray water output control according to the spray curing adjustment coefficient, so as to achieve a better effect of concrete cyclic spray curing.

[0067] Preferably, in some possible implementations of the embodiments of the present invention, the specific implementation process of the method for obtaining the spray tolerance factor in step S102 includes: Figure 2 , which shows a flow chart of a method for obtaining a spray tolerance factor of an intelligent concrete cyclic spray curing control method provided by an embodiment of the present invention, the method comprising:

[0068] Step S201: according to the time sequence of all the spraying curing processes, determine the time series of the total amount of spraying water and the time series of the total content of hydration products corresponding to all the spraying curing processes.

[0069] The total amount of spray water in all spray curing processes is arranged in chronological order to obtain the corresponding total amount of spray water time series; the total content of hydration products in all spray curing processes is arranged in chronological order to obtain the corresponding total content of hydration products time series. The sequence can better reflect the changes in a set of data, making the subsequent correlation analysis more intuitive.

[0070] Step S202: Calculate the sequence correlation between the total amount of spray water output time series and the total content of hydration products time series based on the Pearson correlation coefficient principle; calculate the information entropy corresponding to the total amount of spray water output time series.

[0071] The serial correlation is the Pearson correlation coefficient between the total amount of spray water and the total content of hydration products; because the total amount of spray water and the total content of hydration products are positively correlated under normal circumstances, according to the principle of the Pearson correlation coefficient, the serial correlation obtained by the Pearson correlation coefficient is more accurate. The information entropy characterizes the degree of disordered fluctuation of the total amount of spray water, and is combined with the serial correlation to more accurately characterize the spray tolerance factor.

[0072] In other possible implementations of the embodiments of the present invention, other methods of characterizing correlation such as cosine similarity may be used to replace the Pearson correlation coefficient to calculate the serial correlation, and other parameters characterizing the fluctuation of a set of data such as variance and standard deviation may be used to replace the information entropy to measure the degree of fluctuation, which will not be further elaborated here. It should be noted that the Pearson correlation coefficient and information entropy are both technical means well known to those skilled in the art, and will not be further elaborated here.

[0073] Step S203: Determine the spray tolerance factor of concrete according to the sequence correlation and information entropy.

[0074] The greater the serial correlation, the smaller the information entropy that characterizes the degree of disordered fluctuation of the total amount of spray water, indicating that the change in the total amount of spray water has a greater impact on the total content of hydration products of concrete, and a smaller amount of curing spray water will also cause a corresponding change in the total content of hydration products, that is, the stronger the tolerance of concrete to spray water, the larger the corresponding spray tolerance factor. Therefore, the serial correlation is positively correlated with the spray tolerance factor; the information entropy is negatively correlated with the spray tolerance factor.

[0075] In a specific implementation of the embodiment of the present invention, the product of the negative correlation mapping value of the information entropy and the sequence correlation is used as the corresponding spray tolerance factor. It should be noted that, in addition to the product, the implementer can also calculate the spray tolerance factor according to the corresponding correlation by other methods, such as the normalized value of the mean and the sum value, etc., which will not be further elaborated here.

[0076] In a specific implementation of the embodiment of the present invention, the process of obtaining the spray tolerance factor is expressed by the formula: ;in, is the spray tolerance factor of concrete; is the serial correlation between the total amount of spray water and the total content of hydration products, that is, the Pearson correlation coefficient; is the information entropy corresponding to the time series of the total amount of spray water; It is a preset adjustment parameter, set to 0.1, to prevent the denominator from being 0; It is the negative correlation mapping value of the information entropy, that is, negative correlation mapping is performed by the inverse method; in addition to the inverse, the implementer may also adopt other negative correlation mapping methods according to the specific implementation environment, such as negative correlation mapping by the inverse of an exponential function with a natural constant as the base, which will not be further elaborated here.

[0077] Preferably, in some possible implementations of the embodiments of the present invention, the specific implementation process of the method for obtaining the hydration reaction intensity coefficient in step S103 includes:

[0078] In each spray curing process, the reference hydration product content change value of the concrete at each sampling time is determined according to the deviation of the hydration product content of the concrete at each sampling time compared with the hydration product content at the previous sampling time; the hydration reaction intensity coefficient of the concrete corresponding to each spray curing is determined according to the overall size of the reference hydration product content change value of the concrete at all sampling times in each spray curing process. The hydration reaction intensity is also the hydration reaction rate. The faster the corresponding hydration product content changes, the greater the corresponding hydration reaction intensity. The difference in hydration product content between adjacent sampling time intervals in time series is used to measure the change rate of the hydration product content, thereby determining the hydration reaction intensity of the concrete corresponding to each spray curing, that is, the hydration reaction intensity coefficient.

[0079] In a specific implementation of the embodiment of the present invention, the process of obtaining the hydration reaction intensity coefficient is expressed by the formula: ;in, For the Hydration reaction intensity coefficient of concrete corresponding to the spray curing process; For the The number of sampling moments corresponding to each spray curing process; For the During the first spray curing process The content of hydration products at each sampling time; For the During the first spray curing process The hydration product content at the sampling time, that is, the The hydration parameter content at the sampling time before the sampling time; is the absolute value symbol.

[0080] Preferably, in some possible implementations of the embodiments of the present invention, the specific implementation process of the method for obtaining the environmental interference factor in step S103 includes: Figure 3 , which shows a flow chart of an environmental interference factor acquisition method of an intelligent concrete cycle spraying curing control method provided by an embodiment of the present invention, the method comprising:

[0081] Step S301: In time sequence, curve fitting is performed according to the hydration reaction intensity coefficient of concrete corresponding to all spray curing times to determine the hydration reaction intensity coefficient time series curve; curve fitting is performed according to the time series sequence of the total content of hydration products to determine the time series curve of the total content of hydration products.

[0082] Compared with the sequence, the curve can more intuitively reflect the change of data, so the hydration reaction intensity coefficient time series curve and the hydration product total content time series curve are obtained for subsequent analysis. It should be noted that curve fitting is a technical means well known to those skilled in the art, and will not be further defined or elaborated here.

[0083] Step S302: negatively correlate the deviation between the tangent slope of the data point corresponding to each spray curing in the hydration reaction intensity coefficient time series curve and the tangent slope of the data point corresponding to the hydration product total content time series curve to determine the local interference degree corresponding to each spray curing.

[0084] Each spray curing will correspond to a data point in the hydration reaction intensity coefficient time series curve and the hydration product total content time series curve. The tangent slope of the data point represents the degree of change of the curve under the corresponding number of spray curing times. The more similar the tangent slopes of the two data points corresponding to each spray curing are, the greater the influence of the hydration reaction intensity coefficient on the total content of hydration parameters in the corresponding spray curing process. Therefore, the deviation of the tangent slope between the two data points is negatively correlated and mapped to obtain the local interference degree corresponding to each spray curing, which represents the interference degree of environmental factors on the hydration product content.

[0085] Step S303: Determine the environmental interference factor of the concrete according to the overall magnitude of the local interference degree corresponding to all the spray curing times.

[0086] Finally, by combining the overall magnitude of the local interference degree of all spray curing times, the overall interference degree of environmental factors on the hydration product content, that is, the environmental interference factor, is determined; the larger the corresponding environmental interference factor, the greater the loss of spray water caused by environmental influences, and the greater the corresponding water demand of concrete. In a specific implementation of an embodiment of the present invention, the average of the local interference degrees corresponding to all spray curing times is used as the environmental interference factor of concrete.

[0087] In a specific implementation of the embodiment of the present invention, the process of obtaining the environmental interference factor is expressed by the formula: ;in, is the environmental interference factor of concrete; is the total number of spray curing processes; For the The tangent slope of the data point corresponding to the second spray curing in the hydration reaction intensity coefficient time series curve; For the The tangent slope of the data point corresponding to the total content of hydration products in the time series curve of the first spray curing; is the absolute value symbol.

[0088] Preferably, in some possible implementations of the embodiments of the present invention, the specific implementation process of the method for obtaining the degradation accumulation factor in step S104 includes: Figure 4 , which shows a flow chart of a method for obtaining a degradation accumulation factor of an intelligent concrete cyclic spraying maintenance control method provided by an embodiment of the present invention, the method comprising:

[0089] Step S401: In the spraying curing process corresponding to the current moment, the concrete surface image at the spraying moment corresponding to each spraying is collected and the number of corresponding convex hull points is determined by a convex hull detection method.

[0090] Lack of maintenance will cause the cement paste on the surface of the concrete to lose moisture, become brittle, and easily separate from the aggregate. This separation may make the aggregate particles more prominent, making the surface granularity more obvious. Therefore, when the spray interval is too large, the concrete will deteriorate, and the degree of deterioration will be reflected by the protruding aggregate particles on the surface. Therefore, the more convex hull points obtained by the convex hull detection method, the more serious the concrete deterioration. It should be noted that the convex hull detection method is a prior art well known to those skilled in the art and will not be further defined or elaborated here.

[0091] In a specific implementation of an embodiment of the present invention, a CCD camera is used to capture a concrete plane image at each capture moment, and the time interval between two adjacent capture moments is set to 1 second. The number of corresponding convex hull points of each concrete plane image is determined by convex hull detection technology. It should be noted that the reason for analyzing the number of convex hull points in the spray curing process corresponding to the current moment is that the spray curing process corresponding to the current moment is closest to the real-time condition of the concrete. The rationality of the spray frequency corresponding to the spray curing process can be measured to a certain extent through the corresponding convex hull point distribution, so that the spray frequency is used as the basic parameter for subsequent real-time spray water output control, making the real-time spray water output control more accurate. Therefore, in a specific implementation of an embodiment of the present invention, the spray curing process corresponding to the current moment is set to the spray curing process that is closest to the current moment and complete.

[0092] Step S402: in the spray curing process corresponding to the current moment, the change amount of the convex hull points at each spraying moment is determined according to the deviation of the number of convex hull points at each spraying moment relative to the number of convex hull points at the previous spraying moment in time sequence.

[0093] Considering that the deteriorated concrete cannot be remedied by the next spraying, the deterioration will continue to manifest, that is, the convex hull points that existed before each moment will continue to exist in the future; therefore, the greater the change in the convex hull points corresponding to adjacent spraying moments, the greater the interval between two adjacent spraying moments compared to the interval between spraying moments when no degradation occurs, the more unreasonable the corresponding spraying frequency setting is, and the more the corresponding spraying frequency needs to be increased. Therefore, further according to step S403, the degradation accumulation factor of the spraying curing process corresponding to the current moment is measured as a whole. It should be noted that considering that the convex hull points existing in each spraying curing process will be reflected in the subsequent spraying curing process, in order to make the obtained degradation accumulation factor more accurate, the change in the number of convex hull points is analyzed.

[0094] Step S403: determining the degradation accumulation factor of the concrete at the current moment according to the overall size of the change in the convex hull points at all spraying moments in the spraying curing process corresponding to the current moment.

[0095] In a specific implementation of the embodiment of the present invention, the process of obtaining the degradation accumulation factor is expressed by the formula: ;in, For the current moment The deterioration accumulation factor of concrete is: For the current moment The number of all spraying moments in the corresponding spray curing process; For the current moment The corresponding spray curing process The number of convex hull points corresponding to each spraying moment; For the current moment The corresponding spray curing process The number of convex hull points corresponding to the spraying moment, that is, The number of convex hull points at the previous spraying moment corresponding to the spraying moment; By analyzing the adjacent spraying moments, the moment when the convex hull point changes can be more clearly determined, and the performance of spraying degradation can be more clearly understood.

[0096] In other possible implementation methods of the embodiments of the present invention, the spraying moment when the number of convex hull points changes is taken as the convex hull change moment, that is, the number of convex hull points between the convex hull change moment and the corresponding previous spraying moment changes; the average of the change amounts of the convex hull points at all convex hull change moments is taken as the degradation accumulation factor, so that the obtained degradation accumulation factor can measure the degree of degradation more accurately.

[0097] Preferably, in some possible implementations of the embodiments of the present invention, the specific implementation process of the method for obtaining the spray curing adjustment coefficient in step S104 includes:

[0098] The spray curing adjustment coefficient is used to adjust the real-time spray water output. The larger the spray curing adjustment coefficient is, the greater the demand of concrete for spray water output is. Therefore, according to the relationship between the spray tolerance factor, environmental interference factor, degradation accumulation factor and the demand of concrete for spray water output, according to the negative correlation mapping value of the spray tolerance factor, environmental interference factor and degradation accumulation factor, the product is combined and normalized to determine the spray curing adjustment coefficient corresponding to the current moment.

[0099] In a specific implementation of the embodiment of the present invention, the process of obtaining the spray maintenance adjustment coefficient is expressed by the formula: ;in, For the current moment Corresponding spray maintenance adjustment coefficient; is the spray tolerance factor of concrete; is the environmental interference factor of concrete; For the current moment The deterioration accumulation factor of concrete under the condition of . is an exponential function with a natural constant as the base. Implementers can adopt other negative correlation mapping methods according to the specific implementation environment, such as , and the reciprocal, where is a hyperbolic tangent function, which will not be further described here. It is a linear normalization function. The implementer can adjust the normalization method according to the specific implementation environment.

[0100] Preferably, in some possible implementations of the embodiments of the present invention, the specific implementation process of the method for controlling the real-time spray water output according to the spray maintenance adjustment coefficient in step S104 includes:

[0101] The spray frequency in the spray curing process corresponding to the current moment is weighted with the positive correlation mapping value of the spray curing adjustment coefficient as the weight, and the corrected spray frequency corresponding to the current moment is determined; the real-time spray water output is controlled according to the corrected spray frequency. The larger the spray curing adjustment coefficient, the greater the demand of concrete for the spray water output, so a larger spray frequency is required to increase the total spray water output, so as to meet the demand of concrete for the spray water output. The degradation accumulation factor when obtaining the spray curing adjustment parameter is obtained in the spray curing process corresponding to the current moment, so the spray frequency in the spray curing process corresponding to the current moment is used as the reference and combined with the spray curing adjustment coefficient for adjustment, so as to obtain a more accurate real-time spray water output. The reason for the positive correlation mapping of the spray curing adjustment coefficient is that the spray curing adjustment coefficient obtained in the embodiment of the present invention is a normalized value, and weighting with the normalized value can only make the spray frequency smaller, so the corrected spray frequency obtained by the positive correlation mapping is more in line with the objective actual situation.

[0102] In a specific implementation of the embodiment of the present invention, the process of obtaining the corrected spray frequency is expressed by the formula: ;in, For the current moment The corresponding corrected spray frequency; For the current moment The corresponding spray frequency during the spray curing process; For the current moment Corresponding spray maintenance adjustment coefficient; It is a preset positive correlation adjustment coefficient, which is set to 0.57. The implementer can adjust it according to the specific implementation environment. It should be noted that the implementer can use other methods to positively map the spray maintenance adjustment coefficient according to the specific implementation environment, such as multiplying it with a preset product coefficient, etc. The preset product coefficient can be set to 2 and can be adjusted by oneself, and no further elaboration is given here.

[0103] Preferably, the method for controlling the real-time spray water output according to the modified spray frequency includes:

[0104] The spray frequency of the next spray curing process corresponding to the current moment is adjusted to the corrected spray frequency. The corrected spray frequency is the spray frequency optimized according to the spray curing process corresponding to the current moment; considering that a single spray curing process is sprayed evenly multiple times, the spray frequency of the next corresponding spray curing process is adjusted to the corrected spray frequency, so as to achieve a better concrete cycle spray curing effect.

[0105] In summary, an intelligent concrete cyclic spraying maintenance control method determines the spray tolerance factor that characterizes the spray tolerance through the temporal correlation between the total amount of spray water and the total content of hydration products and the change in water output, and determines the environmental interference factor that characterizes the environmental impact in combination with the temporal change and trend of the hydration product content, and further determines the degradation accumulation factor of the concrete in combination with the concrete degradation performance during the spraying maintenance process; thereby, the spray maintenance adjustment coefficient obtained by combining the spray tolerance factor, the environmental interference factor and the degradation accumulation factor is used to adaptively and more accurately control the real-time spray water output, so that the effect of concrete cyclic spraying maintenance is better.
