[0002] Concrete is a commonly used engineering material, which is widely used in various fields of water conservancy and hydropower construction projects. After concrete is poured, if the climate is hot and the air is dry, and curing is not carried out in time, the water in the concrete will evaporate rapidly, and cracks will appear on the surface. Once the cracks are formed, they will have a serious impact on the integrity, impermeability and durability of the concrete structure.

However, there are the following problems: the temperature difference between the internal temperature of the concrete and the ambient temperature is not considered, which may cause the surface of the concrete to crack. Summary of the Invention

[0034] Please refer to Figures 1 to 2 as shown in Figure 1 This is the connection block diagram of the intelligent concrete curing system based on temperature and humidity regulation of the present invention; Figure 2 This is the flowchart of the intelligent concrete curing system based on temperature and humidity regulation of the present invention. An embodiment of the present invention provides an intelligent concrete curing system based on temperature and humidity regulation, including:

[0035] A collection unit for collecting the film-covered images of the concrete surface after pouring at a plurality of time points, and collecting the temperature data at a plurality of positions inside the concrete and the ambient temperature data at a plurality of time points;

[0036] An analysis unit, connected to the collection unit, for determining the dry area and the wet area according to the film-covered image, determining the change rate of the dry-wet ratio according to the dry area and the wet area, determining the change rate of the temperature difference according to the temperature data at a plurality of positions and the ambient temperature data, and determining the water evaporation rate in the concrete according to the change rate of the dry-wet ratio and the change rate of the temperature difference;

[0037] A control unit, connected to the analysis unit, for adjusting the curing temperature of the concrete according to the comparison result between the water evaporation rate and a preset first evaporation rate and determining the temperature adjustment range of the curing temperature, and adjusting the water spraying amount / adjusting the spraying frequency according to the comparison result between the water evaporation rate and a preset second evaporation rate and determining the adjusted water spraying amount / the adjusted spraying frequency;

[0038] An execution unit, connected to the control unit, for curing the concrete according to the adjusted curing parameters;

[0039] Wherein, the curing parameters include the curing temperature, the water spraying amount and the spraying frequency.

[0040] It can be understood that after the concrete is poured, a plastic film will be covered on the concrete surface for water conservation curing to prevent the concrete surface from cracking due to dehydration. In the present invention, after the concrete is poured, the film-covered image on the film-covered surface is collected to evaluate the dry and wet states of the concrete, and the temperature data at a plurality of positions inside the concrete and the ambient temperature data are collected to understand the temperature difference between the inside and the outside of the concrete, so as to obtain the change rate of the dry-wet ratio and the change rate of the temperature difference, and further determine the water evaporation rate in the concrete, so as to further adjust the curing parameters and intelligently optimize the concrete curing conditions.

[0041] In implementation, the time interval of the several time points ranges from 0.5 h to 1.2 h. Preferably, the time interval of the several time points is 0.5 h. The several positions may be to divide the interior of the concrete into layers or several unit areas in the shape of regular cubes of the same size, and measure the temperature inside these unit areas. The value ranges of the preset first evaporation rate and the preset second evaporation rate can be determined according to factors such as the mix ratio of the concrete, curing conditions (such as humidity, wind speed, etc.), and the required curing effect. The preset first evaporation rate is less than the preset second evaporation rate. Preferably, the value of the preset first evaporation rate is the average value of the normal evaporation rates of moisture at several time points under the condition of concrete curing and no cracking. The value of the preset second evaporation rate is 1.2 to 1.4 times the average value of the normal evaporation rates of moisture at several time points under the condition of concrete curing and no cracking. Preferably, the value of the preset second evaporation rate is 1.3 times the average value of the normal evaporation rates of moisture at several time points under the condition of concrete curing and no cracking.

[0042] In implementation, the several time points, the several positions for measuring the temperature inside the concrete, the preset first evaporation rate, and the preset second evaporation rate can be determined according to the actual situation, and no specific limitation is made here and will not be elaborated further.

[0043] In implementation, the tool for measuring the temperature inside the concrete in the acquisition unit is an embedded temperature-measuring wire, or it can also be other sensors capable of measuring temperature, which are pre-buried inside the concrete to collect the state information of the concrete. Generally, the type of equipment for measuring the temperature inside the concrete is not specifically limited here and will not be elaborated further.

[0044] The present invention monitors the state change of the concrete in real time by collecting the film-covered images, the temperature inside the concrete, and the ambient temperature at several time points, and then determines the change rate of the dry-wet ratio of the film-covered images and the change rate of the temperature difference between the inside and the outside environment of the concrete at different time points, so as to determine the moisture evaporation rate in the concrete, thereby adjusting the curing parameters, precisely controlling the curing conditions (such as temperature and humidity), further reducing the cracks and deformations during the curing process of the concrete, optimizing the curing effect of the concrete, and improving the construction quality and construction efficiency.

[0045] Specifically, the analysis unit determines the segmentation boundary according to the color characteristics of the film-covered image at a single time point, and divides the film-covered image into a dry area and a wet area according to the segmentation boundary.

[0046] It is understandable that during the process of forming concrete with a film covering, due to various factors such as water evaporation, characteristics of the film covering material, construction operations, and external environmental factors, the water evaporation rates at different parts of the concrete surface are different, thus forming a transition region between the dry and wet areas. By identifying the segmentation boundary, the analysis unit can evaluate the drying condition of the concrete surface.

[0047] Please refer to Figure 3 and Figure 4 as shown in Figure 3 which is a flowchart of the analysis unit of the present invention for determining the segmentation boundary according to the film covering image. Figure 4 which is a schematic diagram of the dry-wet segmentation of the dry area and the wet area in the embodiment of the present invention. The dry area is the blank area, and the wet area is the slanted area. Specifically, the analysis unit determines the segmentation boundary according to the film covering image, including:

[0048] Step S11, the analysis unit extracts the color features of the film covering image;

[0049] Step S12, determining the color segmentation threshold according to the color features;

[0050] Step S13, determining the segmentation boundary according to the color segmentation threshold.

[0051] It is understandable that the colors of the dry area and the wet area in the film covering image are different. The image of the dry area is relatively white, and the image of the wet area is relatively black. Therefore, the boundary with a large color difference can be determined according to the color features of the film covering image as the basis for segmenting the dry area and the wet area. The color segmentation threshold is used to distinguish the color difference between the dry area and the wet area.

[0052] In a specific embodiment, a high-resolution camera (in the acquisition unit) can be used to take pictures of the film covering at several time points. The analysis unit converts the color of the film covering image from the RGB color space to the HSV color space, analyzes the color features of the dry area and the wet area under the saturation S, determines the color segmentation threshold according to the analysis result of the color features, and then determines the segmentation boundary to segment the film covering image into the dry area and the wet area. Generally, when the difference in the saturation values read in the saturation channel is greater than the color segmentation threshold of 0.6, the segmentation boundary is determined, and then the dry area and the wet area in the basis channel of a single segmentation are determined. In implementation, the color threshold is not specifically limited here as long as it can segment the film covering image into the dry area and the wet area according to the color threshold, and details are not described here.

[0053] In a specific embodiment, the analysis unit can utilize (such as corrosion, dilation, edge detection, etc.) to optimize the segmentation result to ensure the accuracy and continuity of the segmentation boundary.

[0054] The analysis unit according to the present invention extracts the color features of the film-covered image, determines the color segmentation threshold according to the color features, determines the segmentation boundary according to the color segmentation threshold, and further segments the dry area and the wet area of the film-covered image, thereby providing key information for subsequent adjustment of curing parameters and helping to optimize the curing effect of concrete.

[0055] Please refer to Figure 5 as shown, which is a flowchart of the analysis unit according to the present invention for determining the change rate of the dry-wet ratio at several time points. Specifically, the analysis unit determines the change rate of the dry-wet ratio at several time points, including:

[0056] Step S21, determining the dry area and the wet area according to the segmentation boundary and the film-covered image at a single time point;

[0057] Step S22, determining the dry-wet ratio according to the dry area and the wet area;

[0058] Step S23, determining the change rate of the dry-wet ratio at several time points according to the dry-wet ratio.

[0059] It can be understood that the dry area and the wet area can be determined at a single time point, and the dry-wet ratio at a single time point can be determined at the same time. And as time progresses, the dry-wet ratio will also gradually change. Therefore, the change rate of the dry-wet ratio at several time points can be determined according to the dry-wet ratio.

[0060] In a specific embodiment, the analysis unit can calculate the number of pixels in the dry area and the wet area, and convert the number of pixels into actual area values according to the resolution and shooting distance of the camera, so as to obtain the dry area and the wet area. At the same time, the dry-wet ratio of the same film-covered image is the ratio of the dry area to the wet area. By comparing the dry-wet ratios at adjacent time points, the change rate of the dry-wet ratio at adjacent time points can be obtained, and then the change rate of the dry-wet ratio at several time points can be obtained. The method for determining the dry area and the wet area can be selected according to the actual situation and is not specifically limited here. As long as the dry area and the wet area can be determined and the dry-wet ratio can be obtained accordingly, it will not be elaborated here.

[0061] The present invention determines the dry area and the wet area according to the segmentation boundary and the film-covered image at a single time point, determines the dry-wet ratio according to the dry area and the wet area, and determines the change rate of the dry-wet ratio at several time points according to the dry-wet ratio, thereby further providing key information for subsequent adjustment of curing parameters and helping to optimize the curing effect of concrete.

[0062] Specifically, the analysis unit determines the concrete temperature value according to the several position temperature data at a single time point, determines the temperature difference value according to the concrete temperature value and the corresponding ambient temperature data, and determines the corresponding temperature difference change rate according to the temperature difference values at several time points.

[0063] It can be understood that the temperature difference value between the internal temperature of the concrete and the external ambient temperature is also one of the reasons affecting the cracking of the concrete.

[0064] In a specific embodiment, the concrete temperature value can be determined according to the average value of the several position temperature data, and at the same time, the temperature difference value is determined according to the difference between the average value and the ambient temperature data. By comparing the temperature difference values at adjacent time points, the temperature difference change rate at adjacent time points can be obtained, and then the temperature difference change rates at several time points can be obtained. In practice, the value range and preferred value of the concrete temperature value can be determined according to the actual situation, which are not specifically limited here and will not be elaborated further.

[0065] The present invention determines the concrete temperature value according to the several position temperature data at a single time point, determines the temperature difference value according to the concrete temperature value and the corresponding ambient temperature data, and determines the temperature difference change rates at several time points according to the temperature difference value, thereby further providing key information for subsequent adjustment of the curing parameters and helping to optimize the curing effect of the concrete.

[0066] Specifically, the analysis unit determines the moisture evaporation characteristics in the concrete according to the change rate of the dry-wet ratio, the temperature difference change rate, the ambient wind speed data, and the distribution of the drying area, where the moisture evaporation characteristics include the moisture evaporation rate and the moisture evaporation direction.

[0067] It can be understood that the magnitude of the ambient wind speed also affects the moisture evaporation rate and the moisture evaporation direction in the concrete. The ambient wind speed will accelerate the air flow on the surface of the concrete, thereby accelerating the moisture evaporation rate on the surface of the concrete. Therefore, the analysis unit determines the moisture evaporation rate and the moisture evaporation direction in the concrete according to the change rate of the dry-wet ratio, the temperature difference change rate, and the ambient wind speed data.

[0068] In a specific embodiment, the moisture evaporation rate at adjacent time points is the product of the change rate of the dry-wet ratio, the temperature difference change rate, and the ambient wind speed data at adjacent time points. The value range and preferred value of the moisture evaporation rate are not specifically limited here, as long as the moisture evaporation rate can be characterized by the change rate of the dry-wet ratio, the temperature difference change rate, and the ambient wind speed data, which will not be elaborated further here.

[0069] In a specific embodiment, the water evaporation direction can be determined according to the ambient wind direction and the drying direction in the ambient wind speed data. During the curing process, the area and distribution of the drying area are constantly changing. Therefore, several drying area change vectors can be determined according to the change of the drying area distribution, and then the drying direction can be determined by summing up the drying area change vectors, and further the water evaporation direction can be determined.

[0070] Specifically, the control unit compares the water evaporation direction with the ambient humidity direction and adjusts the spraying position according to the comparison result.

[0071] In a specific embodiment, the ambient humidity at different positions is collected by the collection unit, and then the ambient humidity direction is determined according to the distribution of the ambient humidity at different positions. If the included angle between the water evaporation direction and the ambient humidity direction is less than a preset included angle (the value range of the preset included angle is 0° to 8°, preferably, the value of the preset included angle is 5°), there is no need to adjust the spraying position; if the included angle between the water evaporation direction and the ambient humidity direction is greater than the preset included angle, the spraying position is adjusted. The spraying position can be adjusted by adjusting the position and angle of the nozzle to adjust the ambient humidity direction to ensure that the sprayed water covers the area that needs to be humidified. The adjustment method of the spraying position, the value range of the preset included angle and the preferred value can be determined according to the actual situation, and no specific limitation is made here and will not be elaborated further.

[0072] Specifically, the control unit compares the water evaporation rate with a preset first evaporation rate and adjusts the curing temperature according to the comparison result. Among them, the control unit determines the temperature adjustment range of the curing temperature according to the difference between the water evaporation rate and the preset first evaporation rate.

[0073] Specifically, if the water evaporation rate is greater than the preset first evaporation rate, the control unit reduces the curing temperature.

[0074] It can be understood that during the concrete curing process, an appropriate water content needs to be maintained to avoid excessive or too slow evaporation. Excessive or too small temperature will also affect the water evaporation during the concrete curing process. Therefore, the water evaporation rate is compared with the preset first evaporation rate. When the water evaporation rate is greater than the preset first evaporation rate, the curing temperature is reduced to reduce the water evaporation.

[0075] In a specific embodiment, the difference between the ratio of the moisture evaporation rate to the preset first evaporation rate and 1 is the first coefficient, and the temperature adjustment range is the product of the first coefficient and the ideal curing temperature. The ideal curing temperature can be determined according to factors such as environmental conditions and film covering characteristics, and no specific limitation is made here. As long as the temperature adjustment range can be determined through the ideal curing temperature, moisture evaporation rate, and preset first evaporation rate, it will not be elaborated here. Preferably, the value of the preset first evaporation rate is the average value of the normal moisture evaporation rates at several time points during concrete curing and in an uncracked state.

[0076] Specifically, the control unit compares the moisture evaporation rate with the preset second evaporation rate and adjusts the water spray amount / adjusts the spray frequency according to the comparison result. The control unit determines the adjusted water spray amount / adjusted spray frequency according to the preset spray frequency, preset spray time, and the difference between the moisture evaporation rate and the preset second evaporation rate.

[0077] Specifically, if the moisture evaporation rate is greater than the preset second evaporation rate, the control unit increases the water spray amount / increases the spray frequency.

[0078] It can be understood that the water spray amount is the water spray amount for a single spray, and the spray frequency is the interval duration between single sprays. During the concrete curing process, it is necessary to maintain an appropriate moisture content and avoid too fast or too slow evaporation. Therefore, the moisture evaporation rate is compared with the preset second evaporation rate. If the moisture evaporation rate is greater than the preset second evaporation rate, the water spray amount is increased or the spray frequency is increased to increase the humidity.

[0079] In practice, the value of the second adjustment coefficient is 1.1 - 1.3. The adjusted water spray amount is the product of the second adjustment coefficient and the preset water spray amount, and the adjusted spray frequency is the product of the second adjustment coefficient and the preset spray frequency. The second adjustment coefficient can be determined according to factors such as environmental conditions and film covering characteristics, and no specific limitation is made here. As long as the second adjustment coefficient is reasonable, can effectively respond to the change of the moisture evaporation rate, and will not make the adjustment of the water spray amount and the spray frequency affect the curing effect, it will not be elaborated here. Preferably, the value of the preset second evaporation rate is 1.3 times the average value of the normal moisture evaporation rates at several time points during concrete curing and in an uncracked state. The value of the second adjustment coefficient is 1.25.

[0080] In a specific embodiment, the preset water spray volume ranges from 0.5 L / m³ to 0.7 L / m³, and the preset spraying frequency ranges from 1 day to 3 days. In practice, the preset water spray volume and the preset spraying frequency are both determined according to factors such as the construction environment, the state of the concrete, the type of concrete, and the curing duration. No specific limitation is made here, as long as the values of the preset water spray volume and the preset spraying frequency are reasonable, do not affect the normal setting of the concrete, and do not cause the concrete to crack. Details are not elaborated here.

[0081] In practice, the uniform and timed spraying during the concrete curing process can be achieved through an automated spraying system, thereby keeping the surface of the concrete moist to improve the quality and strength of the concrete. The automated spraying system can have a remote control function, which is convenient for operators to perform automatic spraying according to the preset water spray volume, the preset spraying frequency, the adjusted water spray volume, and the adjusted spraying frequency.

[0082] In the present invention, the analysis unit determines the water evaporation rate in the concrete according to the change rate of the dry-wet ratio, the change rate of the temperature difference, and the environmental wind speed data, and adjusts the curing temperature according to the water evaporation rate and the preset first evaporation rate, and adjusts the water spray volume / spraying frequency according to the water evaporation rate and the preset second evaporation rate, which further helps to optimize the concrete curing effect.

[0083] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
