[0068] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0069] The embodiments of the present application provide a method for visualizing concrete structure damage based on embedded sensing technology. The method can be executed by at least one of the following electronic devices, including a server and a terminal, that can be configured to execute the method provided by the embodiments of the present application: In other words, the method can be executed by software or hardware installed on a terminal or server device, where the software can be a blockchain platform. The server can include, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0070] Reference Figure 1 FIG. 1 is a flow chart of a concrete structure damage visualization method based on embedded sensing technology according to an embodiment of the present invention. In this embodiment, the concrete structure damage visualization method based on embedded sensing technology includes:

[0071] S1. Receive a damage visualization instruction, and start a concrete testing device according to the damage visualization instruction, wherein the concrete testing device consists of a concrete fixing unit, a data acquisition unit, a surface friction unit, and a high-temperature testing unit.

[0072] It should be explained that the damage visualization command is generally initiated by a concrete tester. For example, Xiao Zhang is a tester at a concrete production plant. The plant has produced a batch of concrete of different specifications. In order to test the damage resistance of concrete of different specifications, he initiates the damage visualization command.

[0073] In an embodiment of the present invention, the device for testing the damage resistance of concrete is a concrete testing device, and the concrete testing device is composed of a concrete fixing unit, a data acquisition unit, a surface friction unit, and a high-temperature testing unit.

[0074] Key points: The concrete fixation unit is used to stabilize the concrete, preventing vibration and inaccurate testing during damage resistance testing. The data acquisition unit captures images of the concrete before and after testing and analyzes the concrete's damage resistance based on these images. The surface friction unit and high-temperature test unit create various high-temperature test conditions, thereby improving the accuracy of concrete damage resistance testing.

[0075] S2. Obtain the concrete to be tested, fix the concrete to be tested to the concrete fixing unit, and start the monitoring device of the data acquisition unit when the fixing operation is completed.

[0076] It should be explained that the concrete to be tested obtained in the embodiment of the present invention has different specifications, wherein the specifications include production specifications, raw materials used, etc.

[0077] In detail, fixing the concrete to be tested to the concrete fixing unit includes:

[0078] Activate the fixture of the concrete fixing unit, wherein the fixture is composed of a pair of square pieces, and the square pieces are parallel and opposite to each other;

[0079] Fix the concrete to be tested using a fixture, wherein one square piece contacts the left end of the concrete to be tested and the other square piece contacts the right end of the concrete to be tested, so that the concrete to be tested is parallel to the horizontal plane;

[0080] actuating a rotator within the concrete fixing unit, wherein the rotator is connected to the fixing unit;

[0081] The rotator is used to drive the concrete to be tested in the fixer to perform a rotation operation. When the concrete to be tested remains parallel to the horizontal plane during the rotation operation, the rotator is stopped and the fixing operation of the concrete to be tested is completed.

[0082] It is understood that the main function of the concrete fixing unit is to fix the concrete. While fixing the concrete, it can also rotate the concrete to be tested, thereby ensuring that different surfaces of the concrete to be tested can withstand different high-temperature tests. In an embodiment of the present invention, the concrete fixing unit includes a fixator and a rotator. The fixator structure is composed of a pair of square pieces. Preferably, the fixator can also be composed of a circular piece, and the central portion of the circular piece or square piece has an open slot. The left and right ends of the concrete to be tested can be placed in the open slot, thereby improving the stability of the fixation.

[0083] S3. Use monitoring equipment to photograph the concrete to be tested to obtain an original concrete image. After transmitting the original concrete image back to the data acquisition unit, set the time and force of the surface friction unit to perform surface friction on the concrete to be tested to obtain friction concrete.

[0084] It is understood that after adjusting the focal length of the monitoring device, the concrete to be tested on the fixture can be directly photographed to obtain the original concrete map. It should be emphasized that in order to prevent shooting errors, the number of original concrete maps should be at least 5.

[0085] In detail, the step of setting the time and force of the surface friction unit, performing surface friction on the concrete to be tested, and obtaining friction concrete includes:

[0086] Receive the time t of performing surface friction on the concrete to be tested i and the force f i , where t i represents the time for performing surface friction on the i-th group of concrete to be tested, f i represents the intensity of surface friction applied to the i-th group of concrete to be tested;

[0087] Set the contact threshold between the friction rod and the concrete to be tested, and i and the force f i , calculate the rotation speed v of the rotator;

[0088] Starting a friction rod of a surface friction unit, wherein the surface friction unit is located in the concrete fixing unit and the length of the friction rod is less than the length of the concrete to be tested;

[0089] The friction rod surface is brought into contact with the concrete surface to be tested, wherein the contact force is the force f i ;

[0090] The rotator is started, wherein the rotation speed of the rotator is the aforementioned v, and the rotator is used to drive the concrete to be tested in the holder to rotate, and the concrete to be tested comes into contact with the friction rod during the rotation. When the friction rod comes into contact with the concrete to be tested, the friction rod is immediately separated, and one contact count is completed;

[0091] Until the contact count is greater than or equal to the contact threshold, and when the rotation time of the rotator is equal to the time t i At the same time, the rotator is stopped, the surface friction operation of the concrete to be tested is completed, and the friction concrete is obtained.

[0092] Importantly, time and force are crucial parameters for evaluating surface friction performance. The longer the time and the greater the force, the greater the friction with the concrete being tested. Therefore, the embodiments of the present invention require setting both time and force. Furthermore, the embodiments of the present invention require performing multiple surface friction operations. Therefore, the first time and force are both minimal, and each subsequent surface friction operation has a greater time and force than the previous one.

[0093] In detail, the contact threshold, time t i and the force f i , calculate the rotation speed v of the rotator, including:

[0094]

[0095] Wherein, v represents the rotation speed of the rotator, n represents the contact threshold, and f j represents the contact force between the friction rod and the concrete to be tested at the jth contact, and f jMust be less than or equal to f i , t j represents the contact time between the friction rod and the concrete to be tested at the jth contact, and t j Must be less than or equal to represents the rounding operation, and α is the weight factor for calculating the rotation speed v of the rotator.

[0096] It should be explained that the friction rod is a tool used to rub against the surface of the concrete to be tested. The surface of the friction rod is brought into contact with the surface of the concrete to be tested, and the force f previously received is applied. i , thereby ensuring that the force applied to the concrete surface under test during the surface friction test is in line with the expected value, ensuring that the variables throughout the entire experimental process are accurate. The contact threshold can be freely set according to user needs. Its main function is to calculate the rotation speed of the rotator and determine the contact count. Therefore, the contact threshold is generally set as an empirical value and a positive integer, which can be set to values ​​such as 5, 8, and 10.

[0097] It should also be explained that the embodiment of the present invention will set the time and force of the surface friction unit multiple times. That is, after completing the first friction and laser irradiation and obtaining the original concrete map, friction concrete map, high-temperature concrete map and airflow concrete map respectively, the time and force of the surface friction unit will be set again, and a new set of friction concrete maps, high-temperature concrete maps and airflow concrete maps will continue to be obtained. Multiple tests can obtain more pictures for verifying the damage resistance of concrete.

[0098] It should be emphasized that the embodiments of the present invention do not keep the friction rod in constant contact with the concrete being tested. This is because prolonged contact between the friction rod and the concrete can cause deformation, which is detrimental to high-temperature analysis of concrete. Instead, the embodiments of the present invention employ a process of contact, separation, and then re-contact to complete the friction operation on the concrete surface, thereby ensuring that the concrete does not deform while achieving a friction effect.

[0099] S4. Using monitoring equipment to photograph the friction concrete to obtain a friction concrete map, and after transmitting the friction concrete map back to the data acquisition unit, starting the high-temperature testing unit, wherein the high-temperature testing unit includes a laser generator and an airflow generator.

[0100] It is understood that after the concrete friction is completed, it is necessary to use monitoring equipment to capture the surface image of the concrete to be tested, so as to facilitate the subsequent damage resistance test of the concrete. In detail, the use of monitoring equipment to capture the friction concrete to obtain the friction concrete image and transmit the friction concrete image back to the data acquisition unit includes:

[0101] Use monitoring equipment to photograph friction concrete and obtain the first friction concrete map;

[0102] Starting the rotator again, wherein the rotation speed of the rotator is less than the rotation speed v;

[0103] Using monitoring equipment to photograph multiple surfaces of the friction concrete in the fixture, obtaining a second, third, ..., mth friction concrete image;

[0104] Summarize and compress the first, second, third, ..., mth friction concrete graphs to obtain the compression concrete graph;

[0105] The compressed concrete map is transmitted back to the data acquisition unit.

[0106] It is understandable that since friction under multiple contacts needs to be performed, in order to ensure that the monitoring equipment can capture the entire surface of the concrete to be tested, the embodiment of the present invention needs to use the rotator to continue to drive the fixer to rotate, so as to capture multiple friction concrete images and transmit them back to the data acquisition unit.

[0107] It should be explained that the high-temperature testing unit described in the embodiment of the present invention includes a laser generator and an airflow generator. The purpose of the laser generator is to burn the surface of the friction concrete to test the damage resistance of the friction concrete. The purpose of the airflow generator is to generate convection in the concrete fixing unit to increase the environmental harshness of the friction concrete when performing high-temperature testing.

[0108] S5. Using a laser generator to emit laser light to the friction concrete to obtain high-temperature concrete, and using monitoring equipment to photograph the high-temperature concrete to obtain a high-temperature concrete image.

[0109] In detail, the method of using a laser generator to emit laser light to friction concrete to obtain high-temperature concrete includes:

[0110] Measure the length of the friction concrete to obtain the concrete length;

[0111] The laser irradiation area is calculated based on the concrete length;

[0112] receiving a test power and a test duration, and starting a laser generator to emit a laser, wherein the power of the emitted laser is the test power;

[0113] The rotator is started, wherein the rotation speed of the rotator is the same as the rotation speed during the friction operation, and the rotator drives the concrete to be tested in the holder to rotate while irradiating the friction concrete with the laser;

[0114] When the irradiation time is equal to the test time, the laser generator is stopped to obtain the high-temperature concrete.

[0115] It is understandable that before laser heating, the length of the friction concrete needs to be accurately measured, and then the laser irradiation area is calculated using the concrete length. A reasonable laser irradiation area can ensure that the laser can cover the concrete surface and prevent the laser irradiation from deviating from the friction concrete, causing experimental errors.

[0116] In detail, the laser irradiation area is calculated based on the length of the concrete, including:

[0117] A plane rectangular coordinate system is established with the plane where the laser generator and the friction concrete are located, wherein the laser generator is the origin of the coordinate system;

[0118] Based on the established plane rectangular coordinate system, the distance between the laser generator and the friction concrete is calculated to obtain the laser distance;

[0119] The maximum distance from the laser generator to the leftmost and rightmost ends of the friction concrete is calculated using the laser distance and concrete length;

[0120] The laser irradiation area is calculated based on the maximum distance.

[0121] See Figure 2 As shown, it is a plane schematic diagram of the laser generator and friction concrete. In this plane schematic diagram, a plane rectangular coordinate system including the X-axis and the Y-axis is established with the laser generator as the origin of the coordinate system. Among them, the area surrounded by the two dotted lines on the left and right of the laser generator as the origin of the coordinate system is the laser irradiation area, and the two dotted lines on the left and right are the farthest distances between the leftmost end and the rightmost end.

[0122] Specifically, the laser irradiation area is obtained by calculating the maximum distance, including:

[0123] Calculate the distance between the leftmost and rightmost ends of the friction concrete and the Y axis to obtain the leftmost Y value and the rightmost Y value respectively;

[0124] The area enclosed by the leftmost Y value, the farthest distance between the leftmost and rightmost ends, and the rightmost Y value is determined to be the laser irradiation area.

[0125] It is understandable that the emitted laser generated by the laser generator needs to be irradiated on the surface of the friction concrete, and the emitted laser needs to be within the laser irradiation area.

[0126] It's understandable that by controlling the laser power and operating time, the concrete heating temperature and duration can be controlled to meet the requirements of consistent experimental conditions. The primary purpose of keeping the rotator's rotational speed the same as that used during the friction operation is to ensure uniform stress and heating of the concrete during the friction and laser irradiation phases, thereby preventing test errors between different groups of concrete due to different rotator rotational speeds.

[0127] S6. After the high-temperature concrete image is transmitted back to the data acquisition unit, an airflow generator is used to generate airflow to the concrete fixing unit, and a monitoring device is used to photograph the high-temperature concrete affected by the airflow to obtain an airflow concrete image.

[0128] In detail, the method of generating airflow to the concrete fixing unit by using an airflow generator and photographing the high-temperature concrete affected by the airflow to obtain an airflow concrete image by using a monitoring device includes:

[0129] Setting the oxygen-air ratio of the airflow generated by the airflow generator and the airflow intensity of the generated airflow;

[0130] generating a simulated airflow based on the oxygen-air ratio and the airflow intensity, and introducing the simulated airflow into the concrete fixing unit;

[0131] The laser generator is started again to emit laser light to the high-temperature concrete, and the high-temperature concrete under the influence of airflow is photographed by monitoring equipment to obtain an airflow concrete image.

[0132] It should be understood that different airflows significantly impact concrete's high-temperature performance. Therefore, to improve the accuracy of high-temperature concrete testing experiments, the present invention also requires simulating different airflow environments. Therefore, it is necessary to set the oxygen-to-air ratio and airflow intensity of the airflow generated by the airflow generator. These two important airflow parameters affect the heat transfer and cooling effects of the airflow on concrete, thereby affecting the temperature distribution and surface properties of the concrete.

[0133] It's important to note that the oxygen-to-air ratio can be set by the person initiating the concrete damage test. For example, if Xiao Zhang sets the oxygen-to-air ratio to 0.2, the airflow generated by the airflow generator will contain 20% oxygen. Furthermore, the airflow intensity can also be determined by the initiator. Once the oxygen-to-air ratio and airflow intensity are set, the airflow generator can generate simulated airflow.

[0134] In addition, the process of restarting the laser generator to emit laser light to the high-temperature concrete is the same as S5, and will not be described in detail in this embodiment of the present invention.

[0135] S7. Using the original concrete image, the friction concrete image, the high-temperature concrete image, and the airflow concrete image as input data of a pre-built surface detection model, and using the surface detection model to obtain the surface damage degree, wherein the surface detection model is constructed based on a convolutional neural network.

[0136] See Figure 3 As shown, these are images of a group of concrete at different stages. The imaging effects at each stage are significantly different. Figure 3The leftmost image is the original concrete image, the middle image is the friction concrete image, and the left image is the airflow concrete image. It can be seen that the concrete images under different conditions are obviously different.

[0137] However, it is understood that the smaller the pixel differences between the friction concrete image, the high-temperature concrete image, and the airflow concrete image compared to the original concrete image, the stronger the concrete's damage resistance. Therefore, this embodiment of the present invention uses a surface detection model built on a convolutional neural network to determine the surface damage level of the concrete under test.

[0138] It should be explained that the main operating principle of the surface detection model is: first, use the convolutional neural network to perform convolution and pooling operations on the original concrete image, friction concrete image, high-temperature concrete image and airflow concrete image in turn to obtain a feature map, and then map the feature map to a single dimension value based on the fully connected layer, and use Softmax to calculate the direct difference degree of each image, that is, the difference degree is the surface damage degree.

[0139] In addition, the surface detection model can also determine the surface damage degree of the concrete to be tested by combining a convolutional neural network with a digital image processing model. Since these methods are all publicly available technical solutions, the embodiments of the present invention will not be described in detail here.

[0140] Furthermore, after testing multiple groups of concrete to be tested and obtaining corresponding surface damage degrees, the embodiment of the present invention further includes: screening out the best concrete from the multiple groups of concrete to be tested based on the surface damage degrees.

[0141] For example, Xiao Zhang tested three groups of concrete with different specifications and found that the second group of concrete had the least surface damage, so he confirmed the second group of concrete as the optimal concrete.

[0142] The present invention aims to solve the problems described in the background technology. The present invention combines concrete testing devices, data acquisition, surface friction and high-temperature testing units to achieve comprehensive testing of concrete, including surface friction, high-temperature testing and simulation of airflow environments. In detail, the original concrete map, friction concrete map, high-temperature concrete map and airflow concrete map obtained by the monitoring equipment are used as input data, and the surface damage degree of the concrete is evaluated using a deep learning surface detection model. Since the present invention uses a variety of testing units and monitoring equipment to conduct comprehensive testing on concrete, including surface friction, damage resistance and simulation of airflow environments, it can more comprehensively evaluate the performance of concrete. On this basis, the present invention greatly reduces the manpower and time consumption in the testing process through the use of automated testing processes and deep learning models. Compared with traditional manual testing methods, this method can complete the test more quickly and has higher efficiency in concrete structure damage testing. Therefore, the present invention can improve the intelligence level of concrete structure damage testing and reduce excessive consumption of time and human resources.
