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

[0069] The embodiment of the present application provides a method for visualizing concrete structure damage based on embedded sensor technology. The execution subject of the method for visualizing concrete structure damage based on embedded sensor technology includes but is not limited to at least one of the electronic devices such as a server and a terminal that can be configured to execute the method provided by the embodiment of the present application.

[0070] Reference Figure 1 FIG. 1 is a flow chart of a concrete structure damage visualization method based on embedded sensor technology provided by an embodiment of the present invention. In this embodiment, the concrete structure damage visualization method based on embedded sensor 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 instruction is generally initiated by a concrete tester. For example, Xiao Zhang is a tester of a concrete production plant. The plant now produces a batch of concrete of different specifications. In order to test the damage resistance of concrete of different specifications, the damage visualization instruction is initiated.

[0073] In the 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] The main function of the concrete fixing unit is to fix the concrete to prevent the concrete from shaking during the damage resistance test, which may cause inaccurate testing. The main function of the data acquisition unit is to capture pictures of the concrete before and after the test, and analyze the damage resistance of the concrete based on the pictures. The main functions of the surface friction unit and the high temperature test unit are to create various high temperature test conditions, thereby improving the accuracy of the concrete damage resistance test.

[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 at the same time after the fixing operation is completed.

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

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

[0078] Starting a 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] The concrete to be tested is fixed by 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] Starting a rotator in the concrete fixing unit, wherein the rotator is connected to the fixing device;

[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 to complete the fixing operation of the concrete to be tested.

[0082] It is understandable that the main function of the concrete fixing unit is to fix the concrete, and while fixing the concrete, the concrete to be tested can be rotated to ensure that different surfaces of the concrete to be tested are subjected to different high temperature tests. In an embodiment of the present invention, the concrete fixing unit includes a fixer and a rotator, and the structure of the fixer is composed of a pair of square pieces. Preferably, the fixer can also be composed of a circular piece, and there is an open hole groove in the central part of the circular piece or the square piece, and the left and right ends of the concrete to be tested can be placed in the open hole groove, 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, and after transmitting the original concrete image back to the data acquisition unit, set the time and strength of the surface friction unit, perform surface friction on the concrete to be tested, and obtain friction concrete.

[0084] It is understandable 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 image. It should be emphasized that in order to prevent shooting errors, the number of original concrete images is at least 5.

[0085] In detail, the step of setting the time and strength 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 intensity f i , where t i represents the time for performing surface friction on the i-th group of concrete to be tested, f i It 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 intensity 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 v, and the concrete to be tested in the fixture is driven by the rotator to rotate and contact the friction rod during the rotation, and the friction rod is immediately separated when the friction rod contacts the concrete to be tested, and a 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 work of the rotator is stopped, the surface friction operation of the concrete to be tested is completed, and the friction concrete is obtained.

[0092] The key point is that time and force are important parameters for evaluating surface friction performance. The longer the time and the greater the force, the stronger the friction on the concrete to be tested. Therefore, the embodiment of the present invention needs to set the time and force. In addition, the embodiment of the present invention needs to perform multiple surface friction operations, so the first time and force are both the minimum, and the time and force of each subsequent surface friction are greater than the previous one.

[0093] In detail, the contact threshold, time t i and intensity 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 , thus ensuring that the force applied to the concrete surface to be tested during the surface friction test is in line with expectations, ensuring that the variables of the entire experimental process are accurate. The contact threshold can be freely set according to user needs, and the main function of the contact threshold is to calculate the rotation speed of the rotator and to determine the contact count. Therefore, the setting of the contact threshold is generally an empirical value and a positive integer, which can be set to 5, 8, 10, etc.

[0097] In addition, it should be explained that the embodiment of the present invention will set the time and strength 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 strength 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 embodiment of the present invention does not always keep the friction rod in contact with the concrete to be tested, because the friction rod and the concrete to be tested will cause deformation when in contact for a long time, and this effect is not conducive to high-temperature analysis of concrete. The embodiment of the present invention adopts the operation of contacting, separating, and then contacting again to complete the friction operation on the concrete surface, thereby ensuring that the concrete does not deform while achieving a friction effect.

[0099] S4. Use 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, start the high temperature test unit, wherein the high temperature test unit includes a laser generator and an airflow generator.

[0100] It is understandable that after the concrete friction is completed, it is necessary to use monitoring equipment to take a surface image of the concrete to be tested, so as to facilitate the subsequent anti-damage performance test of the concrete. In detail, the use of monitoring equipment to take a surface image of the friction concrete to obtain a friction concrete image, and the friction concrete image is transmitted back to the data acquisition unit, including:

[0101] The friction concrete is photographed using monitoring equipment to obtain the first friction concrete image;

[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 diagrams to obtain the compression concrete diagram;

[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 a variety of 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 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 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 when performing the friction operation, and the rotator is used to drive the concrete to be tested in the fixture to rotate while irradiating the rubbing concrete with the emitted laser;

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

[0115] Understandably, before laser heating, it is necessary to accurately measure the length of the friction concrete, and then use the concrete length to calculate the laser irradiation area. 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 and 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 farthest distance.

[0121] See also 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, wherein the area enclosed 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] In detail, the laser irradiation area is obtained by calculating according to the farthest distance, including:

[0123] Calculate the distance between the leftmost and rightmost ends of the friction concrete and the Y axis, and 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 is understandable that by controlling the power and working time of the laser, the heating temperature and time of the concrete can be controlled to meet the requirements of the experiment under the same conditions. The main purpose of the rotation speed of the rotator being the same as the rotation speed when performing the friction operation is to keep the concrete in the friction and laser irradiation stages with the same force and heat uniformity, and to prevent the test errors of different groups of concrete to be tested due to the different rotation speeds of the rotator.

[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 using an airflow generator to generate airflow to a concrete fixing unit and using a monitoring device to photograph high-temperature concrete affected by the airflow to obtain an airflow concrete image 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 transmitting the simulated airflow into the concrete fixing unit;

[0131] The laser generator is started again to emit laser 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 also have a great influence on the high temperature performance of concrete. Therefore, in order to improve the accuracy of the concrete high temperature test experiment, the embodiment of the present invention also needs to simulate 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. The oxygen-to-air ratio and airflow intensity are two important airflow parameters that will affect the heat transfer and cooling effect of the airflow on the concrete, thereby affecting the temperature distribution and surface characteristics of the concrete.

[0133] It should be emphasized that the oxygen-air ratio can be set by the initiator who performs the concrete damage test. For example, if Xiao Zhang sets the oxygen-air ratio to 0.2, it means that the oxygen content in the airflow generated by the airflow generator is 20%. In addition, the value of the airflow intensity can also be determined by the initiator. After the oxygen-air ratio and airflow intensity are set, the simulated airflow can be generated by the airflow generator.

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

[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-constructed 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 also Figure 3 As shown in the figure, it is a group of concrete images at different stages. The imaging effects at each stage are obviously different. Figure 3The leftmost picture is the original concrete picture, the middle one is the friction concrete picture, and the left one is the airflow concrete picture. It can be seen that the concrete pictures under different conditions are obviously different.

[0137] However, it is understandable that the smaller the pixel difference between the friction concrete map, the high temperature concrete map and the airflow concrete map and the original concrete map is, the stronger the damage resistance of the concrete is. Therefore, the embodiment of the present invention uses a surface detection model constructed based on a convolutional neural network to determine the surface damage degree of the concrete to be tested.

[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 calculate the direct difference degree of each image through Softmax, 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 public 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: selecting 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 of different specifications and found that the second group of concrete had the smallest surface damage, so the second group of concrete was confirmed as the optimal concrete.

[0142] The present invention solves 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 environment. 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 detection model of deep learning is used to evaluate the surface damage of concrete. Since the present invention uses a variety of test units and monitoring equipment to conduct comprehensive tests on concrete, including surface friction, damage resistance and simulation of airflow environment, it can more comprehensively evaluate the performance of concrete. On this basis, the present invention greatly reduces the manpower and time consumption in the test process through the use of automated test 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.
