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

[0003] Although there are intelligent temperature and humidity monitoring systems for concrete curing in the prior art, they generally use monitoring modules to monitor the temperature and humidity of the concrete standard curing room in real time, so that users can control the temperature adjustment module and the humidity adjustment module according to the detected temperature and humidity to cure the concrete.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figure 1-2 As shown, Figure 1 It is a connection block diagram of the intelligent concrete curing system based on temperature and humidity regulation of the present invention; Figure 2 The flowchart of the intelligent concrete curing system based on temperature and humidity regulation of the present invention is provided in the embodiment of the present invention. The intelligent concrete curing system based on temperature and humidity regulation includes: A collection unit is used to collect the film-covered images of the concrete surface after pouring at several time points, and to collect the temperature data of several positions inside the concrete and the ambient temperature data at several time points; an analysis unit connected to the acquisition unit, for determining a dry area and a wet area according to the coated image, determining a dry-wet ratio change rate according to the dry area and the wet area, determining a temperature difference change rate according to temperature data of a plurality of positions and ambient temperature data, and determining a water evaporation rate in the concrete according to the dry-wet ratio change rate and the temperature difference change rate; a control unit connected to the analysis unit, configured to adjust the curing temperature of the concrete and determine the temperature adjustment amplitude of the curing temperature according to the comparison result between the water evaporation rate and the preset first evaporation rate, and to adjust the water spraying amount / adjust the spraying frequency according to the comparison result between the water evaporation rate and the preset second evaporation rate and determine the adjusted water spraying amount / adjusted spraying frequency; an execution unit connected to the control unit and used to cure the concrete according to the adjusted curing parameters; The curing parameters include the curing temperature, the water spraying amount and the spraying frequency.

[0026] It is understandable that after the concrete is poured, a layer of plastic film will be covered on the concrete surface for water conservation and maintenance to prevent the concrete surface from drying and cracking due to dehydration. After the concrete is poured, the present invention collects the film image of the film surface after the film is coated to evaluate the dryness and wetness of the concrete, collects temperature data and ambient temperature data at several locations inside the concrete to understand the temperature difference between the concrete and the external environment, thereby obtaining the dry-wet ratio change rate and the temperature difference change rate, and then determines the water evaporation rate in the concrete, thereby further adjusting the curing parameters and intelligently optimizing the concrete curing conditions.

[0027] In implementation, the time intervals of the several time points range from 0.5h to 1.2h. Preferably, the time intervals of the several time points range from 0.5h to 1.2h. Preferably, the time intervals of the several time points range from 0.5h to 0.5h. The several positions may be to divide the interior of the concrete into layers or unit areas according to 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 may be determined according to factors such as the mix ratio of 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 preset first evaporation rate is the average of the normal evaporation rates of water at several time points when the concrete is cured and not cracked, and the preset second evaporation rate is 1.2 to 1.4 times the average of the normal evaporation rates of water at several time points when the concrete is cured and not cracked. Preferably, the preset second evaporation rate is 1.3 times the average of the normal evaporation rates of water at several time points when the concrete is cured and not cracked.

[0028] In implementation, the several time points, the several positions for measuring temperature inside the concrete, the preset first evaporation rate, and the preset second evaporation rate can be determined according to actual conditions, and are not specifically limited here and will not be described in detail.

[0029] In practice, the tool for measuring the internal temperature of concrete in the collection unit is a pre-buried temperature measuring line, or other sensors capable of measuring temperature, which are pre-buried in the concrete to collect the state information of the concrete. Generally, the type of equipment for measuring the internal temperature of concrete is not specifically limited here and will not be elaborated.

[0030] The present invention monitors the state change of concrete in real time by collecting the coating images and the internal temperature of concrete and the ambient temperature at several time points, and then determines the dry-wet ratio change rate of the coating images at different time points and the temperature difference change rate between the inside of the concrete and the external environment, so as to determine the evaporation rate of water in the concrete, thereby adjusting the curing parameters, accurately controlling the curing conditions (such as temperature and humidity), further reducing the cracks and deformation of the concrete during the curing process, optimizing the concrete curing effect, and improving the construction quality and efficiency.

[0031] Specifically, the analyzing unit determines a segmentation boundary according to the color feature of the coating image at a single time point, and segments the coating image into a dry area and a wet area according to the segmentation boundary.

[0032] It is understandable that during the concrete film forming process, due to the influence of various factors such as water evaporation, film material properties, construction operations, and external environmental factors, the water evaporation rates in different parts of the concrete surface are different, thus forming a transition area between the dry and wet areas. By identifying the segmentation boundary, the analysis unit can evaluate the dryness of the concrete surface.

[0033] See also Figure 3 and Figure 4 As shown, Figure 3 This is a flow chart of the analysis unit of the present invention determining the segmentation boundary according to the film image. Figure 4 The dry-wet segmentation diagram of the dry area and the wet area in the embodiment of the present invention is shown in FIG. 1 , wherein the dry area is a blank area and the wet area is a diagonal area. Specifically, the analysis unit determines the segmentation boundary according to the coated image, including: Step S11, the analysis unit extracts the color features of the coating image; Step S12, determining a color segmentation threshold according to the color feature; Step S13: determining the segmentation boundary according to the color segmentation threshold.

[0034] It is understandable that the colors of the dry area and the wet area in the film image are different. The dry area image is white, and the wet area image is black. Therefore, the boundary with large color difference can be determined according to the color characteristics of the film 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.

[0035] In a specific embodiment, a high-resolution camera (in the acquisition unit) can be used to take pictures of the coating at several time points. The analysis unit converts the color of the coating picture from the RGB color space to the HSV color space, and analyzes the color characteristics of the dry area and the wet area under the saturation S. According to the analysis results of the color characteristics, the color segmentation threshold is determined, and then the segmentation boundary is determined to segment the coating image into a dry area and a wet area. Generally, when the difference in the saturation values ​​read under 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 channel based on the single segmentation are determined. In implementation, the color threshold is not specifically limited here, as long as the coating image can be segmented into a dry area and a wet area according to the color threshold, it will not be repeated here.

[0036] In a specific embodiment, the analysis unit may utilize (such as erosion, dilation, edge detection, etc.) to optimize the segmentation result and ensure the accuracy and continuity of the segmentation boundary.

[0037] The analysis unit of the present invention extracts the color features of the coated image, determines the color segmentation threshold according to the color features, determines the segmentation boundary according to the color segmentation threshold, and then segments the dry area and the wet area of ​​the coated image, thereby providing key information for subsequent adjustment of curing parameters and helping to optimize the curing effect of concrete.

[0038] See also Figure 5 As shown, it is a flow chart of the analysis unit of the present invention determining the dry-wet ratio change rate at several time points. Specifically, the analysis unit determines the dry-wet ratio change rate at several time points, including: 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; Step S22, determining a dry-wet ratio according to the area of ​​the dry region and the area of ​​the wet region; Step S23, determining the dry-wet ratio change rate at several time points according to the dry-wet ratio.

[0039] It can be understood that the area of ​​the dry region and the area of ​​the wet region 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. As time progresses, the dry-wet ratio will gradually change, so the dry-wet ratio change rate at several time points can be determined based on the dry-wet ratio.

[0040] 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 an actual area value according to the resolution and shooting distance of the camera, so as to obtain the area of ​​the dry area and the area of ​​the wet area. At the same time, the dry-wet ratio of the same coated image is the ratio of the dry area area to the wet area area. By comparing the dry-wet ratios at adjacent time points, the dry-wet ratio change rate at adjacent time points can be obtained, and then the dry-wet ratio change rate at several time points can be obtained. The method for determining the area of ​​the dry area and the area of ​​the wet area can be selected according to the actual situation, and is not specifically limited here. As long as the dry area area and the wet area area can be clearly identified, and the dry-wet ratio can be obtained, it will not be repeated here.

[0041] The present invention determines the area of ​​the dry region and the area of ​​the wet region according to the segmentation boundary and the coating image at a single time point, determines the dry-wet ratio according to the area of ​​the dry region and the area of ​​the wet region, and determines the rate of change 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.

[0042] Specifically, the analysis unit determines the concrete temperature value according to the temperature data of the several positions 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.

[0043] It is understandable that the temperature difference between the internal temperature of concrete and the external ambient temperature is also one of the reasons that affect concrete cracking.

[0044] In a specific embodiment, the concrete temperature value can be determined according to the average value of the temperature data at the several locations, and the temperature difference value can be 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 rate at several time points can be obtained. In implementation, the value range and preferred value of the concrete temperature value can be determined according to actual conditions, and are not specifically limited here and will not be repeated.

[0045] The present invention determines the concrete temperature value according to the temperature data of the several positions 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 rate at several time points according to the temperature difference value, thereby further providing key information for subsequent adjustment of curing parameters and helping to optimize the curing effect of concrete.

[0046] Specifically, the analysis unit determines the water evaporation characteristics in the concrete according to the dry-wet ratio change rate, the temperature difference change rate, the ambient wind speed data and the distribution of the dry area, wherein the water evaporation characteristics include the water evaporation rate and the water evaporation direction.

[0047] It is understandable that the magnitude of the ambient wind speed will also affect the evaporation rate and direction of water in the concrete. The ambient wind speed will accelerate the air flow on the concrete surface, thereby accelerating the evaporation rate of water on the concrete surface. Therefore, the analysis unit determines the evaporation rate and direction of water in the concrete based on the dry-wet ratio change rate, the temperature difference change rate, and the ambient wind speed data.

[0048] In a specific embodiment, the water evaporation rate at adjacent time points is the product of the dry-wet ratio change rate, the temperature difference change rate, and the ratio of the ambient wind speed data at adjacent time points. The value range and preferred value of the water evaporation rate are not specifically limited here, as long as the water evaporation rate can be characterized by the dry-wet ratio change rate, the temperature difference change rate, and the ambient wind speed data, and no further details are given here.

[0049] 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 maintenance process, the area and distribution of the drying area are constantly changing, so a number of drying area change vectors can be determined according to the change in the distribution of the drying area, and then the drying direction is determined by summing the drying area change vectors, and then the water evaporation direction is determined.

[0050] Specifically, the control unit compares the water evaporation direction with the ambient humidity direction, and adjusts the spray position according to the comparison result.

[0051] In a specific embodiment, the ambient humidity at different positions is collected by a collection unit, and then the ambient humidity direction is determined according to the distribution of the ambient humidity at different positions. If the angle between the water evaporation direction and the ambient humidity direction is less than a preset angle (the preset angle ranges from 0° to 8°, preferably, the preset angle is 5°), there is no need to adjust the spray position; if the angle between the water evaporation direction and the ambient humidity direction is greater than the preset angle, the spray position is adjusted. The spray 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 spray position, the range of values ​​of the preset angle, and the preferred value can all be determined according to actual conditions, and are not specifically limited here and will not be repeated.

[0052] 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, wherein 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.

[0053] Specifically, if the water evaporation rate is greater than a preset first evaporation rate, the control unit lowers the curing temperature.

[0054] It is understandable that during the concrete curing process, it is necessary to maintain an appropriate moisture content to avoid evaporation that is too fast or too slow. Too high or too low a temperature will also affect the evaporation of moisture during the concrete curing process. Therefore, the moisture evaporation rate is compared with the preset first evaporation rate. When the moisture evaporation rate is greater than the preset first evaporation rate, the curing temperature is lowered to reduce the evaporation of moisture.

[0055] In a specific embodiment, the difference between the ratio of the water evaporation rate and 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 characteristics. No specific limitation is made here. As long as the temperature adjustment range can be determined by the ideal curing temperature, the water evaporation rate and the preset first evaporation rate, no further details are given here. Preferably, the value of the preset first evaporation rate is the average of the normal evaporation rates of water at several time points when the concrete is cured and not cracked.

[0056] Specifically, the control unit compares the water evaporation rate with a preset second evaporation rate, and adjusts the water spraying amount / adjusts the spraying frequency according to the comparison result. The control unit determines the adjusted water spraying amount / adjusted spraying frequency according to the preset spraying frequency, the preset spraying time, and the difference between the water evaporation rate and the preset second evaporation rate.

[0057] Specifically, if the water evaporation rate is greater than a preset second evaporation rate, the control unit increases the water spraying amount / increases the spraying frequency.

[0058] It is understandable that the water spraying amount is the water spraying amount of a single spraying, and the spraying frequency is the interval time of a single spraying. During the concrete curing process, it is necessary to maintain an appropriate moisture content to avoid evaporation that is too fast or too slow. Therefore, the water evaporation rate is compared with the preset second evaporation rate. If the water evaporation rate is greater than the preset second evaporation rate, the water spraying amount is increased or the spraying frequency is increased to increase the humidity.

[0059] In implementation, the second adjustment coefficient is 1.1 to 1.3, the adjusted water spray volume is the product of the second adjustment coefficient and the preset water spray volume, 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 environmental conditions, film characteristics and other factors. No specific limitation is made here. As long as the second adjustment coefficient can be reasonable, it can effectively respond to changes in water evaporation rate and will not affect the curing effect by adjusting the water spray volume and the spray frequency, it will not be repeated here. Preferably, the preset second evaporation rate is 1.3 times the average of the normal evaporation rate of water at several time points when the concrete is cured and not cracked. The second adjustment coefficient is 1.25.

[0060] In a specific embodiment, the preset water spray volume ranges from 0.5L / m³ to 0.7L / m³, and the preset spray frequency ranges from 1 day to 3 days. In implementation, the preset water spray volume and the preset spray frequency are determined based on factors such as the construction environment, concrete state, concrete type, and curing time. No specific limitation is made here. As long as the preset water spray volume and the preset spray frequency can be reasonably set, the normal solidification of the concrete will not be affected, and the concrete will not be cracked, no further details will be given here.

[0061] In practice, the automated spraying system can be used to achieve uniform and timed spraying during concrete curing, thereby keeping the concrete surface 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 automatically spray according to preset water spraying volume, preset spraying frequency, adjusted water spraying volume, and adjusted spraying frequency.

[0062] The analysis unit in the present invention determines the evaporation rate of water in the concrete according to the dry-wet ratio change rate, the temperature difference change rate and the ambient wind speed data, and adjusts the curing temperature according to the water evaporation rate and the preset first evaporation rate, and adjusts the water spraying amount / adjusts the spraying frequency according to the water evaporation rate and the preset second evaporation rate, which further helps to optimize the curing effect of the concrete.

[0063] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying 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.
