Description

[0002] During the concrete mixing and transportation process, the quality of fresh concrete is affected by factors such as the particle morphology of coarse aggregate, the powder content of fine aggregate, the concentration and dosage of admixtures.

[0003] It often takes more than half an hour or even an hour for concrete to be transported from the factory to the construction site due to the distance and traffic conditions. During transportation, the concrete is constantly stirred as the tank rotates, and the real-time status of the concrete in the tank cannot be known at this time. After a period of transportation, when the mixer truck arrives at the construction site, there is a certain probability that the concrete will have poor working performance and fail to meet the construction requirements. Concrete that arrives at the construction site may have problems such as segregation and bleeding, and over-drying due to water evaporation, which makes the concrete impossible to construct and needs to be returned, causing large economic losses and delaying the progress of on-site construction.

[0004] It is difficult to observe the working status of concrete in a running mixer truck manually, which requires the observer to have rich experience. This method is difficult to monitor the whole process because it is not real-time, and if the observer is not experienced, the judgment of the working performance of concrete is not accurate.

[0050] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0051] In the description of this application, if there is a description of first, second, etc., it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0052] In the description of the present application, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0053] In the description of this application, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meaning of the above terms in this application based on the specific content of the technical solution.

[0054] Since it is difficult to observe the working status of concrete in a running mixer truck in real time manually, the observer must have rich experience. This method is difficult to monitor the whole process because it is not real-time, and if the observer is not experienced, the judgment of the working performance of concrete is not accurate.

[0055] In order to solve the above-mentioned problems of lack of real-time performance and inaccurate work performance judgment, this embodiment proposes a method, system, device and medium for judging the work performance of concrete in a tank.

[0056] Reference Figure 1 The present application provides a method for determining the working performance of concrete in a tank, the method comprising the following steps:

[0057] Step S100, obtaining a concrete surface slurry image and an image to be judged, wherein the concrete surface slurry image is an image of the concrete surface slurry taken during a plurality of groups of tests on the working performance of concrete in the tank, the image to be judged is an image of the concrete surface slurry whose working performance is currently to be judged, and the working performance is to judge whether the concrete in the tank is in a normal working state or an abnormal working state;

[0058] Step S200, identifying coarse aggregate in the concrete surface paste image and marking the outline of the coarse aggregate;

[0059] Step S300, calculating the exposure degree of the coarse aggregate according to the contour of the coarse aggregate;

[0060] Step S400, constructing a reference database including a range of exposure degrees of coarse aggregate corresponding to a normal working state;

[0061] Step S500: judging the working performance of the concrete in the current tank according to the reference database and the image to be judged.

[0062] In this embodiment, by acquiring a slurry image on the concrete surface and an image to be judged, coarse aggregate in the slurry image on the concrete surface is identified, and the outline of the coarse aggregate is marked. By acquiring images in real time, the outline of the coarse aggregate is identified and marked, thereby laying a good data foundation for realizing real-time monitoring. According to the outline of the coarse aggregate, the degree of exposure of the coarse aggregate is calculated, and then a reference database containing the range of the degree of exposure of the coarse aggregate corresponding to the normal working state is constructed. Finally, according to the reference database and the image to be judged, the working performance of the concrete in the current tank is judged, so that real-time monitoring can be realized, and the accuracy of the working performance judgment is improved, thereby saving labor costs.

[0063] In some embodiments, identifying coarse aggregate in a concrete surface paste image and marking the outline of the coarse aggregate includes:

[0064] Binarization segmentation is used to identify coarse aggregate in the concrete surface paste image and mark the outline of the coarse aggregate.

[0065] In this embodiment, binary segmentation and recognition are adopted to accurately segment the slurry and the coarse aggregate, thereby accurately marking the outline of the coarse aggregate.

[0066] In some embodiments, calculating the exposure degree of the coarse aggregate according to the contour of the coarse aggregate includes:

[0067] Calculate the total surface area of ​​concrete and the area of ​​individual coarse aggregate;

[0068] Based on the area of ​​a single piece of coarse aggregate, calculate the total area of ​​coarse aggregate;

[0069] The ratio between the total surface area of ​​concrete and the total area of ​​coarse aggregate is calculated to obtain the degree of exposure of coarse aggregate.

[0070] In this embodiment, the ratio between the total surface area of ​​concrete and the total area of ​​coarse aggregate is calculated to obtain the degree of exposure of coarse aggregate. The degree of exposure of coarse aggregate can be obtained by acquiring images in real time, which can lay a good data foundation for real-time monitoring of the working performance of concrete.

[0071] In some embodiments, the total area of ​​the coarse aggregate is calculated based on the area of ​​a single piece of coarse aggregate, comprising:

[0072] Screening the single coarse aggregate according to the area of ​​the single coarse aggregate to obtain the screened single coarse aggregate;

[0073] Add the areas of all screened individual coarse aggregates to obtain the total area of ​​coarse aggregate.

[0074] In this embodiment, in order to improve the calculation accuracy of the exposure degree of coarse aggregate, the single coarse aggregate is screened according to the area of ​​the single coarse aggregate to obtain the screened single coarse aggregate, and the areas of all the screened single coarse aggregates are added together to obtain the total area of ​​the coarse aggregate.

[0075] In some embodiments, constructing a reference database containing a range of exposure levels of coarse aggregate corresponding to normal working conditions includes:

[0076] Record the basic information of concrete, test performance and exposure degree of coarse aggregate during the concrete performance test of each group of tanks, where the basic information is used to indicate the corresponding volume, grade and proportion of coarse aggregate in the mix ratio of concrete in each group of tanks;

[0077] Determine the test work performance corresponding to the basic information of the concrete in each group of tanks, wherein the test work performance includes at least one of a normal working state and an abnormal working state;

[0078] The exposure degree of coarse aggregate corresponding to the basic information of concrete in each group of tanks is associated with the test working performance. If the test working performance is in a normal working state, the exposure degree of coarse aggregate is normal; if the test working performance is in an abnormal working state, the exposure degree of coarse aggregate is abnormal.

[0079] The range of coarse aggregate exposure under normal working conditions is recorded, and a benchmark database is constructed based on the range of coarse aggregate exposure under normal working conditions.

[0080] In this embodiment, by associating the exposure degree of coarse aggregate corresponding to the basic information of concrete in each group of tanks with the test working performance, and building a benchmark database according to the range of the exposure degree of coarse aggregate under normal working conditions, a good data foundation is laid for real-time monitoring in the later stage. In the later stage, it is only necessary to obtain images and calculate the exposure degree of coarse aggregate based on the images to judge the working performance of the concrete in the tank, without the need to judge based on manual experience, so that the working status judgment is more accurate.

[0081] In some embodiments, determining the test performance corresponding to the basic information of concrete in each group of tank bodies includes:

[0082] Test the slump and expansion corresponding to the basic information of concrete in each tank;

[0083] Based on the slump and expansion, the test work performance corresponding to the basic information of the concrete in each tank body is determined.

[0084] In this embodiment, the test working performance corresponding to the basic information of concrete in each group of tanks is judged according to the slump and expansion, and the test working performance can be judged more accurately. This makes the correlation between the exposure degree of coarse aggregate constructed later and the test working performance more accurate, thereby obtaining a more accurate range of the exposure degree of coarse aggregate corresponding to the normal working state.

[0085] It should be noted that, in this embodiment, the slump and spread corresponding to the basic information of concrete in each group of tank bodies are tested, and the existing technology is used to measure the slump and spread, which will not be described in detail in this embodiment.

[0086] The above slump can refer to the plasticity and pumpability of concrete. The factors that affect the slump of concrete mainly include gradation changes, water content, weighing deviation of scales, dosage of admixtures, and the temperature of cement, which is easily overlooked. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete.

[0087] The above expansion can be the diameter of the concrete expansion during the test and is often used to evaluate the pumpability and molding properties of concrete.

[0088] In some implementations, judging the working performance of concrete in the current tank according to the reference database and the image to be judged includes:

[0089] Calculate the exposure degree of coarse aggregate corresponding to the image to be judged;

[0090] If the exposure degree of the coarse aggregate corresponding to the image to be judged is within the normal range of the exposure degree of the coarse aggregate in the reference database, it is judged that the working performance of the concrete in the current tank is in a normal working state;

[0091] If the exposure degree of the coarse aggregate corresponding to the image to be judged is not within the normal range of the exposure degree of the coarse aggregate in the reference database, it is judged that the working performance of the concrete in the current tank body is in an abnormal working state.

[0092] In this embodiment, the working performance of the concrete in the current tank is judged according to the calculated exposure degree of the coarse aggregate corresponding to the image to be judged and the normal range of the exposure degree of the coarse aggregate in the reference database, thereby achieving real-time monitoring, improving the accuracy of the working performance judgment, and saving labor costs.

[0093] To facilitate understanding by those skilled in the art, a set of best embodiments is provided below:

[0094] During the concrete mixing and transportation process, the quality of fresh concrete is affected by factors such as the particle morphology of coarse aggregate, the powder content of fine aggregate, the concentration and dosage of admixtures. When the concrete is loaded into the transport tank truck and transported from the mixing plant to the construction site, in order to maintain the working performance of the concrete, the tank of the transport truck continues to rotate to prevent the concrete from segregating. Due to the distance and traffic conditions, it often takes more than half an hour or even an hour for the concrete to be transported from the factory to the construction site. During the transportation process, the concrete is continuously stirred as the tank rotates, and the real-time status of the concrete in the tank cannot be known at this time. After a period of transportation, when the mixer truck arrives at the construction site, there is a certain probability that the concrete has poor working performance and does not meet the construction requirements. The concrete that arrives at the construction site may have problems such as segregation and bleeding and water evaporation leading to over-dryness, which makes the concrete unable to be constructed and needs to be returned, causing large economic losses and delaying the progress of on-site construction.

[0095] During the period from the time when concrete passes the quality inspection to the time when it arrives at the construction site, the concrete is in the tank of the moving transport vehicle, so the personnel cannot check the state of the concrete and make timely adjustments. For concrete that does not meet the construction requirements when it arrives at the site, the on-site technicians can only adjust the state of the concrete by using admixtures, and the concrete that does not meet the requirements after adjustment can only be returned. When making technical adjustments to concrete, the technical personnel have high requirements for their abilities, and at the construction site, the labor team members often add water privately to improve the fluidity of the concrete, which directly leads to problems with the strength and durability of the concrete in the later stage.

[0096] In order to ensure smooth construction after the concrete arrives at the site and reduce the problem of concrete returns due to poor workability, it is necessary to monitor the state of the concrete in the transport mixer truck to ensure that the concrete meets the construction requirements after arriving at the site. However, it is difficult to manually observe the working state of the concrete in the running mixer truck in real time, and it requires the observer to have rich experience, is not real-time, and is difficult to monitor the entire process.

[0097] In order to solve the above problems, this application proposes a method for judging the working performance of concrete in a tank based on machine vision recognition, which monitors the state of concrete in the tank in real time and performs corresponding processing, and realizes the online detection and judgment of the working performance of concrete in the tank using machine vision recognition technology. The method for judging the working performance of concrete in a tank in this embodiment specifically includes the following steps:

[0098] S1. Image data acquisition: by adding an image video data acquisition module at the feed port of the mixer truck, the state image of the surface of the concrete during the rotation and mixing in the mixer truck is collected to obtain the image of the concrete surface slurry (i.e., the concrete surface slurry image).

[0099] Figure 2 This is a picture of the concrete surface slurry in the tank of a mixer truck. It can be seen in the picture that the concrete surface slurry is divided into two parts. One part is cement mortar mixed with cement, water, sand, other powder materials and admixtures, and the other part is the stone exposed on the concrete surface. Because the stone and cement mortar are mixed together, the stone also shows the color of the mortar. Carefully observe the concrete surface picture, the cement mortar part is relatively flat, while the stone is protruding on the concrete surface. Stone, as a coarse aggregate, plays the role of a skeleton in concrete. Cement mortar fills the gaps between stones and bonds the stones. When the concrete fluidity is better, the cement slurry will wrap all the stones, and the working performance of the concrete is better at this time. When the amount of cement mortar in the concrete is not enough to wrap the stones, the stones will protrude on the surface of the concrete, and the concrete will be dry as a whole, showing poor working performance.

[0100] The above-mentioned image and video data acquisition module may include devices for image acquisition such as cameras and video cameras.

[0101] S2. The collected image of the concrete surface slurry in the tank is transmitted to the processor, and the image of the concrete surface slurry in the tank is analyzed to obtain the degree of exposure of the coarse aggregate in the concrete surface slurry. The degree of exposure of the coarse aggregate in the concrete surface slurry refers to the phenomenon that the coarse aggregate cannot be completely wrapped by the slurry during the continuous mixing of the concrete in the tank truck due to insufficient slurry or poor fluidity contained in the concrete, resulting in the coarse aggregate being exposed on the surface. Use the image and video data acquisition module to collect images of the surface slurry of the mixing concrete, perform binary segmentation processing on the collected images, and then identify them. Since the grayscale values ​​of the slurry and coarse aggregate in the image are different, and the coarse aggregate exposed on the surface will show raised features, the coarse aggregate particles are selected by identifying the boundaries of the coarse aggregate. Specifically:

[0102] like Figure 3 As shown, Figure 3 a) is a partial picture of the surface slurry of concrete in the tank of the mixer truck. Figure 3 b) is a schematic diagram of the boundary of the coarse aggregate particles on the concrete surface (i.e., the outline of the coarse aggregate) after processing the local image. The area of ​​the graphics in the processed local image is calculated using the image pro plus software to obtain the total area A of the concrete paste surface and the area A of a single aggregate in the processed image. 0 , the total area of ​​coarse aggregate A t and the proportion of aggregate on the concrete surface L g =A t / A*100%, to determine the exposure degree of coarse aggregate on the surface of the slurry. The total area A of the concrete slurry surface is the area of ​​the collected surface image, and the area A of a single aggregate is 0 The area enclosed by the outline of each coarse aggregate particle is identified. The total area of ​​the coarse aggregate is A. t is the area A of all single coarse aggregates 0 The area A of a single aggregate is calculated by identification. 0 The size should be larger than the particle size of a single coarse aggregate particle. 0 When the value is less than the lower limit of the coarse aggregate particle size, it should be removed. The proportion of aggregate on the concrete surface L g =A t / A*100%,L g Indicates the proportion of coarse particles on the surface of the concrete, L g The larger the value is, the worse the wrapping rate of the paste on the coarse aggregate in the concrete is.

[0103] This embodiment uses an image video data acquisition module to acquire images of the state of the concrete slurry surface every 60 seconds, thereby achieving real-time and continuous monitoring of the exposure degree of coarse aggregate on the concrete surface.

[0104] The above-mentioned particle size may be the size of the coarse aggregate particles.

[0105] The lower limit of the coarse aggregate particle size can be changed according to actual conditions, and this embodiment does not impose any specific limitation.

[0106] S3. Establish a machine judgment benchmark database.

[0107] The benchmark database collects the factory working performance, on-site working performance and status images (i.e., images of the concrete surface paste in the tank) of multiple groups of freshly mixed concrete. By judging the working performance, it is determined whether the batch of concrete is normal, and the working performance status is associated with the exposure degree of coarse aggregate. Among them, the basic data indicators of working performance collected are slump, expansion and status judgment results. The exposure degree of coarse aggregate is calculated based on the status image, and the characteristic data of concrete in the process is recorded. The characteristic data includes the exposure degree of coarse aggregate on the surface of the paste, and the characteristic data value of concrete in normal state is obtained.

[0108] According to the degree of exposure of coarse aggregate on the surface of concrete paste obtained by analysis, the characteristic data is compared with the data in the benchmark database, and the characteristic data that exceeds the normal working state range is selected, and the working performance of the batch of concrete is judged as abnormal, and the data judged as abnormal working performance is removed. Record the concrete information such as the strength grade, volume and proportion of coarse aggregate in the mix ratio of each batch of concrete, and obtain the coarse aggregate exposure value when the concrete state in the tank is judged as normal (N) through the accumulated data. Specifically:

[0109] For a batch of concrete, the recorded data are as follows:

[0110] ① Volume F, ② Strength grade C, ③ Ratio of coarse aggregate in mix ratio Q, ④ Slump T, ⑤ Expansion K, ⑥ Status judgment result P, ⑦ Exposure degree of coarse aggregate L g .

[0111] For a batch of concrete, obtain concrete information such as strength grade, volume, and proportion of coarse aggregate in the mix ratio, test the slump and expansion corresponding to the concrete information, obtain the judgment result of the concrete working state, and associate the exposure degree of coarse aggregate obtained by collecting image analysis with the judgment result of the concrete working state. If the working state of the batch of concrete is judged to be normal, the corresponding exposure degree of coarse aggregate is the normal value (N); if the working state of the batch of concrete is judged to be abnormal, the corresponding exposure degree of coarse aggregate is the abnormal value (F). The above will get a set of valid data, that is, through the basic information of concrete (volume F, strength grade C and proportion of coarse aggregate in the mix ratio Q), the state result P is judged by the working performance parameters (slump T and expansion K), so as to determine the exposure degree L of coarse aggregate. g Whether the result is a normal value (N).

[0112] By accumulating the data set when the working state is normal, the concrete with basic information (F, C, Q) and the exposure degree L of coarse aggregate corresponding to the working state are obtained. g normal range.

[0113] S4. Machine judgment and analysis: The data collection module transmits the collected data to the data processing module, processes the collected status data, and verifies whether the concrete working status is normal.

[0114] The data collected above include real-time images of the concrete surface slurry (i.e., images to be judged) and basic information.

[0115] The above processing of the collected state data may be processing the collected pictures of the concrete surface paste and calculating the exposure degree of the coarse aggregate.

[0116] For concrete with input basic information (F, C, Q), determine the exposure degree of coarse aggregate L obtained in real time g Is the value within the normal working range? If the exposure degree of coarse aggregate L g If the value is within the normal range, the working state is judged to be normal (output is N); if the exposure degree of coarse aggregate is L g If the value is not within the normal range, it is judged as abnormal working state (output is F). If the working state is judged as F, a warning should be issued in time.

[0117] In this embodiment, by establishing the relationship between the exposure degree of coarse aggregate on the concrete surface and the working state of the concrete, a specific analysis is performed on the concrete state characteristic values ​​obtained in real time, thereby realizing real-time monitoring of the working state of the concrete in the tank of the mixer truck during transportation. This embodiment can more intuitively judge the working state of the concrete in the tank, has the characteristics of timeliness and accuracy, eliminates the need for manual testing of working performance, saves labor costs, improves work efficiency, and improves the accuracy of working state judgment.

[0118] Reference Figure 4 The embodiment of the present application also provides a system for judging the working performance of concrete in a tank body, the system comprising a data acquisition unit 100, a contour marking unit 200, a data calculation unit 300, a database construction unit 400 and a working performance judgment unit 500, wherein:
