Description

Technical Field

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

[0002] With the continuous development of urban construction in my country, cast-in-place concrete and precast concrete are widely used in actual projects. The concrete vibration technology closely related to them has gradually matured. Concrete vibrators include insert type, attachment type, flat plate type, etc., and are manually operated during vibration.

[0003] After pouring concrete into the mold, it must be fully vibrated to assist the flow of concrete, eliminate bubbles in the concrete, make the concrete denser, and avoid the occurrence of honeycombs, rough surfaces, holes, etc.; on-site concrete pouring construction often uses a vibrator to vibrate the concrete. The vibrator includes an electric motor, a transmission flexible shaft, and a vibrating rod. The rotation of the motor is transmitted to the vibrating rod through the transmission flexible shaft, causing the vibrating rod to release high-frequency vibrations; when in use, the construction workers insert the vibrating rod into the concrete and use the vibrating rod to output vibrations to the concrete to compact the concrete.

[0004] Chinese Patent Publication No. CN115506595A discloses a concrete vibrating system and method, comprising: a base mounted above the concrete in the area to be vibrated; a pull-wire displacement sensor mounted on the bottom surface of the base, with one end of the detection wire extending outside the pull-wire displacement sensor forming a connection end; a hollow vibrating ball; a vibration assembly mounted within the vibrating ball; a first control unit mounted within the vibrating ball and controllably connected to the vibration assembly; a wire retracting assembly mounted on the bottom surface of the base and symmetrically located on either side of the pull-wire displacement sensor; a suspension rope wound around the wire retracting assembly, with one end of the suspension rope away from the wire retracting assembly mounted and connected to the vibrating ball; and a second control unit mounted on the base, controllably connected to the pull-wire displacement sensor and the wire retracting assembly. The vibrating ball is raised a certain distance for each set vibration time, achieving automated vibration. This technical solution suffers from the following problems: it fails to consider the impact of concrete properties on the vibration effect, making it impossible to dynamically adjust the vibration parameters during on-site construction based on the concrete properties, thus affecting the efficiency of concrete vibration. Summary of the Invention

[0005] To this end, the present invention provides an intelligent vibration method and system for concrete, which is used to overcome the problem that the existing technology does not consider the influence of concrete properties on the vibration effect, cannot dynamically adjust the vibration parameters according to the properties of concrete, and affects the vibration efficiency of concrete.

[0006] In one aspect, the present invention provides an intelligent vibrating method for concrete, comprising: The concrete sample is placed in the extrusion module, which extrudes the concrete onto the receiving plate at a constant speed. After a preset dwell time, the detection module obtains image information of the receiving plate surface and obtains the sample image information. determining the outer edge perimeter of the concrete feature in the identified sampled image information as a concrete flow parameter; Determine whether the concrete vibration parameters are qualified based on the concrete flow parameters, including: Determine if the vibration parameters of the concrete are abnormal, adjust the vibration amplitude of the concrete to the corresponding value based on the concrete flow parameters, and control the supervision module to periodically obtain construction image information; Identify bubble features in a plurality of acquired construction image information for a single construction area, and count the number of bubbles in each construction image information; draw a bubble number time domain curve based on the number of bubbles; and calculate the slope of the bubble number time domain curve to obtain a bubble change representation value for the single construction area; Determining whether to correct the vibration parameters of the concrete based on the bubble change characterization value, and when determining the corrected vibration parameters of the concrete, correcting the vibration parameters of the concrete based on the bubble comparison parameter, including adjusting the vibration frequency of the concrete or adjusting the vibration duration of the concrete; Acquire a plurality of construction image information for a single construction area; calculate the ratio of the average area of ​​each bubble feature of the current construction image to the average area of ​​each bubble feature of the initial construction image to obtain a bubble comparison parameter.

[0007] Furthermore, the process of the analysis module determining whether the vibration parameters of the concrete are qualified based on the concrete flow parameters includes: comparing the concrete flow parameters with preset concrete flow parameters; If the concrete flow parameter is less than or equal to the preset concrete flow parameter, it is determined that the vibration parameter of the concrete is abnormal, and the vibration amplitude of the concrete is adjusted to a corresponding value based on the concrete flow parameter, and the control monitoring module periodically obtains construction image information; If the concrete flow parameter is greater than the preset concrete flow parameter, it is determined that the vibration parameters of the concrete are qualified, and the preset vibration parameters are continuously used to complete the vibration of the concrete.

[0008] Furthermore, the process of the data processing module determining whether to modify the vibration parameters of the concrete based on the bubble change characterization value includes: Comparing the bubble change characterization value with a preset bubble change characterization value; If the bubble variation characterization value is less than or equal to the preset bubble variation characterization value, the vibration parameters of the concrete are corrected based on the bubble comparison parameter; If the bubble change characterization value is greater than the preset bubble change characterization value, it is determined that the vibration parameters of the concrete are qualified, and the current vibration parameters are continuously used to complete the vibration of the concrete.

[0009] Furthermore, in the process of the data processing module adjusting the vibration amplitude of the concrete to a corresponding value based on the concrete flow parameter, the increase in the vibration amplitude is negatively correlated with the concrete flow parameter.

[0010] Furthermore, the process of the data processing module adjusting the vibration parameters of the concrete based on the bubble comparison parameter includes: Comparing the bubble comparison parameter with the preset bubble comparison parameter; If the bubble comparison parameter is less than or equal to the preset bubble comparison parameter, the vibration frequency of the concrete is adjusted to a corresponding value based on the bubble comparison parameter; If the bubble comparison parameter is greater than the preset bubble comparison parameter, the vibration time of the concrete is adjusted to a corresponding value based on the bubble change characterization value.

[0011] Furthermore, in the process of the data processing module adjusting the vibration frequency of the concrete to a corresponding value based on the bubble comparison parameter, the increase amplitude of the vibration frequency is negatively correlated with the bubble comparison parameter.

[0012] Furthermore, in the process where the data processing module is used to adjust the vibration duration of the concrete to a corresponding value based on the bubble change characterization value, the increase in the vibration duration is negatively correlated with the bubble change characterization value.

[0013] On the other hand, the present invention also provides an intelligent vibration system using the above-mentioned intelligent vibration method for concrete, comprising: The load-bearing module includes a receiving plate placed at an angle; An extrusion module, which is arranged on one side of the receiving plate and is used to extrude concrete; A detection module, which is arranged on one side of the receiving plate and is used to obtain sampling image information of the surface of the receiving plate; an analysis module connected to the detection module, for determining concrete flow parameters based on the sampled image information, and for determining whether the vibration parameters of the concrete are qualified based on the concrete flow parameters; a supervision module connected to the analysis module and configured to determine whether to periodically acquire construction image information based on a determination result of the analysis module; A data processing module is connected to the supervision module and the analysis module respectively, and is used to determine the bubble change characterization value based on the construction image information, to determine whether the vibration parameters of the concrete are qualified based on the bubble change characterization value, and to adjust the vibration parameters of the concrete when it is determined that the vibration parameters of the concrete are abnormal. The vibration parameters include vibration frequency, vibration amplitude and vibration duration.

[0014] Compared with existing technologies, the present invention has the following advantages: it determines concrete flow parameters based on sampled image information, and determines the eligibility of concrete vibration parameters based on these parameters; it also determines the eligibility of concrete vibration parameters based on bubble variation characterization values; and when abnormalities are determined, adjusts the vibration parameters, which include vibration frequency, vibration amplitude, and vibration duration. By monitoring and analyzing concrete flow parameters and bubble variation characterization values, vibration problems during on-site construction can be promptly identified, and vibration parameters can be adjusted when abnormalities occur, thus ensuring the quality of concrete vibration.

[0015] Furthermore, the concrete flow parameter characterizes the concrete's flowability. The higher the concrete's flowability, the greater the range it flows on the docking plate, the longer the outer edge circumference, and the easier it is to vibrate. The concrete flow parameter determines whether the concrete's vibration parameters are qualified. The outer edge circumference of the concrete features in the identified sampled image information is used as the concrete flow parameter. The concrete's flowability is closely related to the range of its flow on the docking plate. The roughness of the docking plate surface in different areas provides more variation in the flow of sampled concrete, making it easier to visualize the concrete's flow. The larger the outer edge circumference, the farther the concrete flows on the docking plate, and the stronger its flowability. This quantifies the concrete's flowability. When the concrete flow parameter is less than or equal to the preset concrete flow parameter, the concrete's flowability is poor, making vibration more difficult and requiring adjustment of the vibration amplitude. When the concrete flow parameter is greater than the preset concrete flow parameter, the concrete's flowability is good, and vibration can be completed using the preset vibration parameters. When the concrete's flowability is poor, the cement paste viscosity is high, the friction between the aggregates is also high, and air bubbles are difficult to expel. Increasing the vibration amplitude at this time can increase the force exerted by the vibrator on the concrete, creating greater relative movement among the concrete particles, thereby promoting the expulsion of bubbles. For concrete with good flowability, the preset vibration parameters are sufficient to meet the vibration requirements. By monitoring and analyzing the concrete's flow parameters, problems during on-site construction vibration can be promptly identified and vibration parameters adjusted accordingly, ensuring the quality of concrete vibration and improving the efficiency of concrete vibration during construction.

[0016] Furthermore, for the construction areas corresponding to the sampled concrete whose concrete flow parameters are less than or equal to the preset concrete flow parameters, the construction conditions are further monitored according to the bubble change characterization value during the construction process. The construction conditions of concrete with low flow capacity and difficult vibration are analyzed and monitored in detail. During the vibration process, the bubbles inside the concrete will rise and be discharged under the action of the vibration force. As the vibration time increases, the number of bubbles will gradually decrease. The bubble change characterization value characterizes the dynamic changes in the bubble discharge of concrete during the vibration process. The bubble change characterization value reflects the speed and stability of bubble discharge during the vibration process. When the bubble change characterization value is greater than the preset bubble change characterization value, the bubble discharge speed will be relatively stable and the vibration parameters are appropriate. When the bubble change characterization value is less than or equal to the preset bubble change characterization value, the slope is too small. At this time, there is a sudden slowdown in the bubble discharge speed, and the bubble discharge is abnormal. The vibration parameters are adjusted based on the bubble comparison parameters; the vibration parameters are automatically adjusted according to the analysis results, thereby improving the accuracy and reliability of the construction. During the analysis and operation process, construction data is continuously accumulated, which can provide a reference for subsequent construction. Through the analysis and summary of historical data, the vibration parameters are further optimized, and the construction quality and efficiency are improved.

[0017] Furthermore, the vibration parameters are adjusted based on the bubble comparison parameter, and the ratio of the average area of ​​each bubble feature of the current construction image to the average area of ​​each bubble feature of the initial construction image is calculated to obtain the bubble comparison parameter. When the bubble comparison parameter is less than or equal to the preset bubble comparison parameter, the bubbles become significantly smaller during the vibration process. Since the vibration amplitude is too large, the particles inside the concrete vibrate violently, causing the bubbles to be squeezed and become smaller. In this case, when the bubble change characterization value is too small, the speed of bubble discharge suddenly slows down. It is determined that the bubbles are difficult to discharge due to their smaller size. At this time, the vibration frequency is increased to stimulate the bubbles to rise. When the bubble change characterization value is greater than the preset bubble change characterization value, the bubble size change is within the normal range. The vibration effect is further optimized by adjusting the vibration time to ensure that the bubbles are fully discharged. During the construction process, the vibration parameters are adaptively adjusted to improve the vibration efficiency, reduce unnecessary vibration time and energy consumption, and thus reduce construction costs. While ensuring construction efficiency, the vibration efficiency of concrete is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 3 as well as Figure 4 As shown, they are respectively a structural schematic diagram and a side view of a docking plate according to an embodiment of the present invention. In this embodiment, the docking plate 1 is provided with a rough surface 11 and a smooth surface 12 at equal intervals, and the docking plate 1 is arranged obliquely.

[0026] Specifically, there is no limitation on the inclination angle of the receiving plate 1. In this embodiment, preferably, the angle between the receiving plate 1 and the horizontal plane is 60°, which will not be described in detail.

[0027] Specifically, there is no limitation on the specific structure of the extrusion module, and it can be any extrusion device. It is understandable that it can achieve uniform extrusion of the concrete to be tested. This is a prior art and will not be described in detail.

[0028] Specifically, before construction, concrete is sampled and placed in the extrusion module, which extrudes a fixed amount of concrete onto the receiving plate 1 at a constant speed. After a preset dwell time, the detection module obtains image information of the surface of the receiving plate 1 to obtain sampling image information.

[0029] Specifically, there is no limitation on the specific structures of the detection module and the monitoring module, which can be cameras and will not be described in detail.

[0030] Specifically, the analysis module is used to determine the concrete flow parameters based on the sampled image information, including: The method is used to determine the outer edge perimeter of the concrete feature in the identified sampling image information as the concrete flow parameter.

[0031] Specifically, there is no limitation on the specific method for identifying the concrete features in the sampled image information. An image edge detection algorithm such as the Canny edge detection algorithm may be used. This is a prior art and will not be described in detail.

[0032] Specifically, the analysis module is used to determine whether the vibration parameters of the concrete are qualified based on the concrete flow parameters, including: If the concrete flow parameter is less than or equal to the preset concrete flow parameter, it is determined that the vibration parameter of the concrete is abnormal, and the vibration amplitude of the concrete is adjusted to the corresponding value based on the concrete flow parameter. The control monitoring module periodically obtains construction image information; If the concrete flow parameter is greater than the preset concrete flow parameter, it is determined that the vibration parameters of the concrete are qualified, and the preset vibration parameters are continuously used to complete the vibration of the concrete.

[0033] Specifically, the preset concrete flow parameter C0 is selected within the interval [0.82L0, 0.89L0], L0 is the average value of each concrete flow parameter obtained from the historical data, and there is no limit on the number of selected historical concrete flow parameters. It can be understood that in order to classify the flow capacity of concrete, the number of selected historical concrete flow parameters should be no less than 1000.

[0034] Specifically, there is no limitation on the selection of preset vibration parameters. In this embodiment, preferably, the vibration amplitude is 50 mm, the vibration frequency is 2000 r / min, and the vibration time is 30 s.

[0035] Specifically, the construction image information is image information of the concrete surface periodically acquired by a monitoring module deployed at the construction site after concrete vibration begins.

[0036] Specifically, the construction site is divided into several construction areas, and the supervision module monitors each construction area separately to obtain a number of construction image information for each construction area.

[0037] Specifically, the concrete flow parameter characterizes the concrete's flowability. The higher the concrete's flowability, the greater the range over which it flows on the receiving plate 1, the longer the outer perimeter, and the easier it is to vibrate. The concrete flow parameter is used to determine whether the concrete's vibration parameters are qualified. The outer perimeter of the concrete feature in the identified sampled image information is used as the concrete flow parameter. The concrete's flowability is closely related to the range over which it flows on the receiving plate 1. The provision of roughened surfaces 11 in different areas of the receiving plate 1 surface provides more variation in the flow of sampled concrete, making it easier to visualize the concrete's flow. The larger the outer perimeter, the farther the concrete flows on the receiving plate 1, and the greater its flowability. This quantifies the concrete's flowability. When the concrete flow parameter is less than or equal to the preset concrete flow parameter, the concrete's flowability is poor, making vibration more difficult and requiring adjustment of the vibration amplitude. When the concrete flow parameter is greater than the preset concrete flow parameter, the concrete's flowability is good, and vibration can be completed using the preset vibration parameters. When concrete has poor flowability, the viscosity of the cement paste inside is high, and the friction between the aggregates is also high, making it difficult for bubbles to be expelled. Increasing the vibration amplitude in this case can increase the force exerted by the vibrator on the concrete, causing greater relative movement of the particles within the concrete, thereby promoting the expulsion of bubbles. For concrete with better flowability, the preset vibration parameters are sufficient to meet the vibration requirements. By monitoring and analyzing the concrete flow parameters, problems in the vibration process can be promptly identified and the vibration parameters can be adjusted according to the actual situation, thereby ensuring the vibration quality of the concrete and improving the vibration efficiency.

[0038] Specifically, the data processing module is used to determine the bubble change representation value based on each construction image information, including: Used to obtain a number of construction image information for a single construction area; Used to identify bubble features in each construction image information; Used to count the number of bubbles of each construction image information; Draw a time domain curve of the number of bubbles based on the number of each bubble; The slope of the time domain curve of the bubble number is solved to obtain the bubble change characterization value for a single construction area.

[0039] Specifically, there is no limitation on the specific method of identifying bubble features, and it can be determined based on the shape target detection algorithm OpenCV contour detection. This is an existing technology and will not be described in detail.

[0040] Specifically, the data processing module is used to determine whether to adjust the vibration parameters of the concrete based on the bubble change characterization value, including: If the bubble variation characterization value is less than or equal to the preset bubble variation characterization value, adjusting the vibration parameters of the concrete based on the bubble comparison parameter; If the bubble change characterization value is greater than the preset bubble change characterization value, it is determined that the vibration parameters of the concrete are qualified, and the current vibration parameters are continuously used to complete the vibration of the concrete.

[0041] Specifically, the preset bubble change characterization value Y0 is selected within the interval [0.7B0, 0.75B0], and B0 is the average value of the historical bubble change characterization values.

[0042] Specifically, for the construction area corresponding to the sampled concrete whose concrete flow parameter is less than or equal to the preset concrete flow parameter, the construction situation is further monitored according to the bubble change characterization value during the construction process. The construction situation of concrete with low flow capacity and difficult vibration is analyzed and monitored in detail. During the vibration process, the bubbles inside the concrete will rise and be discharged under the action of the vibration force. As the vibration time increases, the number of bubbles will gradually decrease. The bubble change characterization value characterizes the dynamic changes in the bubble discharge of concrete during the vibration process. The bubble change characterization value reflects the speed and stability of bubble discharge during the vibration process. When the bubble change characterization value is greater than the preset bubble change characterization value, the bubble discharge speed will be relatively stable and the vibration parameters are appropriate. When the bubble change characterization value is less than or equal to the preset bubble change characterization value, the slope is too small. At this time, there is a sudden slowdown in the bubble discharge speed, and the bubble discharge is abnormal. The vibration parameters are adjusted based on the bubble comparison parameters; the vibration parameters are automatically adjusted according to the analysis results, which improves the accuracy and reliability of the construction. During the analysis and operation process, a large amount of construction data is continuously accumulated. The accumulated data can provide reference and reference for subsequent construction. Through the analysis and summary of historical data, the vibration parameters and construction technology are further optimized, and the construction quality and efficiency are improved.

[0043] Specifically, the data processing module is used to adjust the vibration amplitude of the concrete to a corresponding value based on the concrete flow parameter, wherein: The increase in vibration amplitude is negatively correlated with the concrete flow parameters.

[0044] In this embodiment, optionally, Comparing the concrete flow parameter with a first preset flow comparison threshold and a second preset flow comparison threshold; If the concrete flow parameter is less than or equal to the first preset flow comparison threshold, the vibration amplitude of the concrete is adjusted to 1.29 times the initial vibration amplitude; If the concrete flow parameter is less than or equal to the second preset flow comparison threshold and greater than the first preset flow comparison threshold, the vibration amplitude of the concrete is adjusted to 1.18 times the initial vibration amplitude; If the concrete flow parameter is greater than the second preset flow comparison threshold, the vibration amplitude of the concrete is adjusted to 1.11 times the initial vibration amplitude; The first preset flow comparison threshold is 0.6C0, and the second preset flow comparison threshold is 0.75C0.

[0045] Specifically, the data processing module is used to adjust the vibration parameters of concrete based on the bubble comparison parameter, including: Used to obtain a number of construction image information for a single construction area; Calculating the ratio of the average area of ​​each bubble feature of the current construction image to the average area of ​​each bubble feature of the initial construction image to obtain a bubble comparison parameter; If the bubble comparison parameter is less than or equal to the preset bubble comparison parameter, the vibration frequency of the concrete is adjusted to a corresponding value based on the bubble comparison parameter; If the bubble comparison parameter is greater than the preset bubble comparison parameter, the vibration time of the concrete is adjusted to a corresponding value based on the bubble change characterization value.

[0046] Specifically, the preset bubble comparison parameter D0 is selected within the interval [0.3, 0.4].

[0047] Specifically, during the construction process, the sampled concrete corresponds to several construction areas. When the vibration parameters of the concrete are determined to be abnormal based on the concrete flow parameters, the construction areas corresponding to the sampled concrete are obtained to determine whether the vibration parameters of the concrete in each construction area are qualified based on the bubble change characterization value, and then determine whether to adjust the vibration parameters of the concrete in the corresponding construction area based on the bubble comparison parameters.

[0048] Specifically, under the condition that the bubble comparison parameter is less than or equal to the preset bubble comparison parameter, the vibration amplitude of the concrete is adjusted to 0.8 times the current vibration amplitude.

[0049] Specifically, the vibration parameters are adjusted based on the bubble comparison parameter, and the ratio of the average area of ​​each bubble feature of the current construction image to the average area of ​​each bubble feature of the initial construction image is calculated to obtain the bubble comparison parameter. When the bubble comparison parameter is less than or equal to the preset bubble comparison parameter, the bubbles become significantly smaller during the vibration process. Since the vibration amplitude is too large, the particles inside the concrete vibrate violently, causing the bubbles to be squeezed and become smaller. In this case, when the bubble change characterization value is too small, the speed of bubble discharge suddenly slows down. It is determined that the bubbles are difficult to discharge due to their smaller size. At this time, the vibration frequency is increased to stimulate the bubbles to rise. When the bubble change characterization value is greater than the preset bubble change characterization value, the bubble size change is within the normal range. The vibration effect is further optimized by adjusting the vibration time to ensure that the bubbles are fully discharged. Adjust the vibration parameters to improve the vibration efficiency, reduce unnecessary vibration time and energy consumption, and thus reduce construction costs. While ensuring construction efficiency, the vibration efficiency of concrete is further improved.

[0050] Specifically, the data processing module is used to adjust the vibration frequency of the concrete to a corresponding value based on the bubble comparison parameter, wherein: The increase in vibration frequency is negatively correlated with the bubble ratio parameter.

[0052] Specifically, the data processing module is used to adjust the vibration duration of the concrete to a corresponding value based on the bubble change characterization value, wherein: The increase in vibration time is negatively correlated with the bubble change characterization value.

[0053] In this embodiment, optionally, Comparing the bubble change characterization value with a first preset change comparison threshold and a second preset change comparison threshold; If the bubble change characterization value is less than or equal to the first preset change comparison threshold, the vibration time of each construction area corresponding to the sampled concrete is adjusted to 1.27 times the initial vibration time; If the bubble change characterization value is less than or equal to the second preset change comparison threshold and greater than the first preset change comparison threshold, the vibration time of each construction area corresponding to the sampled concrete is adjusted to 1.21 times the initial vibration time; If the bubble change characterization value is greater than the second preset change comparison threshold, the vibration time of each construction area corresponding to the sampled concrete is adjusted to 1.12 times the initial vibration time; The first preset change comparison threshold is 0.6Y0, and the second preset change comparison threshold is 0.7Y0.
