Abstract
Description
Technical Field
[0001] The present application relates to the field of building detection technology, and in particular to a method, system, storage medium and intelligent terminal for dynamic detection of building structures. Background Art
[0002] Today, people are paying increasing attention to the safety monitoring and surveillance of major projects. Damage accumulation and catastrophic behavior in large structures and infrastructure are becoming increasingly prominent. During the use of building structures, various catastrophic factors inevitably lead to the accumulation of damage and the degradation of their resistance, which can lead to structural failure and even catastrophic accidents.
[0003] Concrete is the most widely used structural material in civil engineering. Monitoring of concrete structures typically involves using acoustic, optical, electrical, magnetic, and radiographic methods to measure physical quantities related to concrete performance and infer its strength, density, uniformity, and defects. Common monitoring methods include rebound, ultrasonic, radiographic, and vertical reflection, but each has its limitations. The rebound method can only monitor the quality of concrete surfaces; ultrasonic data is significantly affected by coupling conditions and rebar; vertical reflection requires both the reflector source and the receiving detector to exhibit short aftershock characteristics and address the trade-off between high frequency and high power; and the radar echo signal's discernibility is affected by the presence of rebar in the concrete.
[0004] Regarding the above-mentioned related technologies, the inventors believe that the detection sensors need to be attached to the tested building, and the limitations of the sensor's own structure result in "point" detection. It is easy to fail to detect structural damage because the damage point is far away from the sensor, and there is still room for improvement. Summary of the Invention
[0005] In order to improve the problem that the detection is "point" type due to the limitations of the sensor's own structure, and the damage to the structure cannot be detected because the damage point is far away from the sensor, the present application provides a dynamic detection method, system, storage medium and intelligent terminal for building structures.
[0006] In a first aspect, the present application provides a method for dynamic detection of building structures, which adopts the following technical solutions:
[0007] A building structure dynamic detection method, comprising:
[0008] Get current time information and current current information;
[0009] Calculate the current resistance information of the carbon fiber test plate glued to the building body based on the current current information and the preset circuit parameter information;
[0010] forming resistance change curve information according to current time information and current resistance information;
[0011] Analyze the current resistance change rate information corresponding to the current time information according to the resistance change curve information;
[0012] Analyze the current resistance change acceleration information based on the current resistance change rate information;
[0013] Determine whether the current resistance change acceleration information is greater than a preset slow change threshold;
[0014] If it is greater than, the structure destruction status information is output;
[0015] If it is less than, output slight damage information.
[0016] By adopting the above technical solution, the carbon fiber detection plate bonded to the building is determined, and then the dynamic changes of the building are converted into changes in the appearance of the carbon fiber detection plate, so as to determine the degree of internal damage. The detection range is large, and the reliability and accuracy of the detection are improved.
[0017] Optionally, the method further includes continuing monitoring if the current resistance change acceleration information is greater than the slow change critical value, the method comprising:
[0018] Obtain overall image information;
[0019] Analyze the overall image information according to the preset building color information to determine the crack characteristic information of the carbon fiber detection plate;
[0020] Determining left and right viewing angle information of a curve corresponding to the crack characteristic information according to the crack characteristic information;
[0021] Acquire crack feature information using left and right viewing angle information respectively to determine a viewing angle at which the crack feature information can be acquired, and define the viewing angle as crack viewing angle information;
[0022] Determine low area information based on crack feature information and crack viewing angle information;
[0023] Press the area corresponding to the low area information to obtain the forward distance information and contact pressure information;
[0024] Determine whether the forward distance information increases when the contact pressure information obtained is greater than 0;
[0025] If it increases, the carbon fiber test plate corresponding to the low area information is not pressed, and then the area corresponding to the low area information is re-applied with glue;
[0026] If it does not increase, continue to obtain the current current information.
[0027] By adopting the above technical solution, when a fault occurs, the area of the lower side after the crack is pressed to determine whether the lower side has separated from the wall and become debonded when subjected to shear stress. If debonding occurs, the adhesion between the carbon fiber test plate and the building wall can be maintained by repairing the glue, and the subsequent changes in the building can be observed before the carbon fiber test plate is replaced, thereby improving the range and duration of dynamic detection.
[0028] Optionally, a method for determining low area information is further included, the method comprising:
[0029] Determine the area information on both sides based on the crack feature information and the overall image information;
[0030] Determine the total pressing direction information, the low area information to be verified, and the high area information according to the crack viewing angle information;
[0031] Determine pressing direction information according to crack characteristic information;
[0032] Partition the low area information to be verified according to the total pressing direction information, the sub-pressing direction information, and the preset single pressing area size information to obtain pressing unit area information and pressing sequence information;
[0033] Press the area corresponding to the high area information to obtain the verified forward distance information;
[0034] Pressing the areas corresponding to all the pressing unit area information according to the pressing sequence information and obtaining the forward distance information and the contact pressure information, defining the forward distance information as the detected forward distance information and the contact pressure information as the detected contact pressure information;
[0035] When the detected forward distance information does not increase, the detected contact pressure information is increased;
[0036] When the detected contact pressure information increases but the detected forward distance information still does not increase, determining whether the detected forward distance information is greater than the verified forward distance information;
[0037] If equal, it is defined as the leveling unit area information;
[0038] If it is greater than, it is defined as low unit area information;
[0039] After all the pressed unit area information is judged, the low unit area information is integrated into the low area information.
[0040] By adopting the above technical solution, by pressing on the other side of the detection plate, it is possible to determine whether there is a gap between the detection plate and the wall and to know the range of low-area information coverage, which facilitates detection, saves detection costs, and improves detection efficiency.
[0041] Optionally, after all the pressed unit area information is judged, the method of integrating the low unit area information into the low area information includes:
[0042] Get the current pre-detection unit area information;
[0043] Determine crack median information based on crack characteristic information;
[0044] Segmenting the pressing direction information according to the crack median information to obtain approaching segmented pressing direction information and distant segmented pressing direction information;
[0045] Determine total adjacent detected unit area information and sub-adjacent detected unit area information according to current pre-detection unit area information, total pressing direction information, and sub-pressing direction information;
[0046] When the sub-pressing order corresponding to the sub-adjacent detected unit region information is close to the direction of the segmented pressing sub-direction information and is flat unit region information, and the total adjacent detected unit region information is flat unit region information, the current pre-detected unit region information is directly determined to be flat unit region information;
[0047] Determine whether the total adjacent detected unit area information is leveled unit area information;
[0048] If the total adjacent detected unit area information is the flattened unit area information, the current pre-detected unit area information is directly determined to be the flattened unit area information without pressing;
[0049] If the total adjacent detected unit area information is not the flat unit area information, then determining whether the sub-pressing order corresponding to the sub-adjacent detected unit area information is the order corresponding to the away-segmented pressing sub-direction information;
[0050] If the adjacent detected unit area information is not far from the direction of the segmented pressing direction information, a pressing judgment is performed on the area corresponding to the current pre-detection area information;
[0051] If the sub-adjacent detected unit region information is in a direction away from the segmented pressing sub-direction information, then the sub-adjacent detected unit region information is determined to be flattened unit region information;
[0052] If it is the leveling unit region information, the current pre-detection unit region information is directly determined to be the leveling unit region information without pressing.
[0053] By adopting the above technical solution, the inherent characteristics of the debonding situation are utilized, that is, the carbon fiber detection plate and the building body are generally separated from the crack to the side away from the crack, and the separation area gradually extends to the side away from the crack, so it is a shape similar to half an ellipse. Therefore, when some special situations occur, it is possible to directly determine whether there is debonding, thereby improving the judgment efficiency of the area corresponding to the low area information.
[0054] Optionally, a method for re-gluing the area corresponding to the low area information includes:
[0055] Determine reverse gluing sequence information according to the pressing sequence information and the low area information;
[0056] Get the current gluing unit area information;
[0057] Determine the maximum forward distance information of the current gluing unit area information;
[0058] Calculate the unit glue quantity information based on the maximum forward distance information and the preset unit size information;
[0059] Calculate the glue spraying speed information based on the unit glue quantity information and unit size information;
[0060] Insert the glue spraying hose from the crack into the area corresponding to the low area information between the carbon fiber detection plate and the building body and move it in the direction of the reverse glue coating sequence information. When the current unit is the current glue coating unit area information, glue is applied according to the glue spraying speed information.
[0061] By adopting the above technical solution, the glue is applied in the reverse order and with the corresponding amount of glue, and the low area information is filled while ensuring sufficient adhesion between the carbon fiber test plate and the building body, so that the carbon fiber test plate always maintains a gradual transition to the other side, thereby improving the accuracy of the carbon fiber test plate detection.
[0062] Optionally, an auxiliary method for glue spraying is also included, which includes:
[0063] Determine low cell boundary region information and corresponding adjacent leveling cell region information according to the low region information and the leveling cell region information;
[0064] Determine glue spraying time information of low unit boundary area information according to reverse glue coating sequence information and preset glue spraying tube moving speed information;
[0065] Calculate the softening time information according to the glue spraying time information and the preset softening time information;
[0066] At the softening moment, the corresponding adjacent flattened unit area information is heated and softened from the side of the carbon fiber detection plate away from the building body.
[0067] By adopting the above technical solution, the area adjacent to the boundary area of the low area information is heated, so that the temperature in the adjacent area is increased, the glue in the middle is softened, and thus comes into contact with and dissolves with the glue entering the low area information, thereby reducing the stratification of the glue and improving the adhesion of the glue.
[0068] Optionally, the method of moving the glue spraying tube in the direction opposite to the glue coating sequence information and applying glue according to the glue spraying speed information when the current unit is the current glue coating unit area information includes:
[0069] Determine whether the maximum forward distance information is less than the preset glue hose diameter information;
[0070] If it is greater than, the area will be sprayed normally;
[0071] If it is less than, the low unit area information is defined as unreachable area information;
[0072] Determine, according to the total pressing direction information, information of unreachable areas located in the same direction, and define a set corresponding to the information of unreachable areas as unreachable area group information;
[0073] determining unreachable depth information based on the unreachable area group information;
[0074] Perform matching analysis on the glue spraying force curve information and the inaccessible depth information stored in a preset glue spraying database to determine the glue spraying force curve corresponding to the inaccessible depth information, and define the glue spraying force curve as the filling glue spraying force curve information;
[0075] After removing all unreachable area group information from the reverse gluing sequence information, the order of the unreachable area group information is arranged after the removed reverse gluing sequence information, and the reverse gluing sequence information is updated, and the updated reverse gluing sequence information is defined as adjusted reverse gluing sequence information;
[0076] Move the glue spraying hose in the direction of adjusting the reverse gluing sequence information and when the current unit is the current gluing unit area information, glue is applied according to the glue spraying speed information. When the order corresponding to the area group information cannot be reached, glue is sprayed according to the filling glue spraying impact curve information at the end closest to the crack in the area corresponding to the area group information that cannot be reached.
[0077] By adopting the above technical solution, when some parts are too small for the glue spraying hose to enter, the order is adjusted to leave a channel similar to injection molding, and then glue is flushed into the corresponding channel with a certain force for spraying, thereby improving the glue spraying efficiency of the glue spraying hose.
[0078] In a second aspect, the present application provides a building structure dynamic detection system, which adopts the following technical solutions:
[0079] A building structure dynamic detection system, comprising:
[0080] An acquisition module is used to obtain current time information, current current information, overall image information, current pre-detection unit area information, and current glue coating unit area information;
[0081] A memory for storing a program for a control method of any one of the above-mentioned building structure dynamic detection methods;
[0082] The program in the processor memory can be loaded and executed by the processor to implement any of the control methods of the above-mentioned building structure dynamic detection methods.
[0083] By adopting the above technical solution, the carbon fiber detection plate bonded to the building is determined, and then the dynamic changes of the building are converted into changes in the appearance of the carbon fiber detection plate, so as to determine the degree of internal damage. The detection range is large, and the reliability and accuracy of the detection are improved.
[0084] In a third aspect, the present application provides a smart terminal, which adopts the following technical solutions:

The detection range is large, and the reliability and accuracy of the detection are improved.
[0091] In summary, this application includes at least the following beneficial technical effects:

[0104] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.
[0105] The present application embodiment discloses a method for dynamic detection of building structures. Figure 1 , a building structure dynamic detection method includes:
[0106] Step 100: Acquire current time information and current current information.
[0107] The current time information is the information of the detection time. The current current information is the information of the current passing through the identification circuit. Figure 2 As shown, the building body is coated with a coating layer, which can be an epoxy resin adhesive. The adhesive will soften when heated to a certain temperature and solidify below a certain temperature. A carbon fiber detection plate is provided on the coating layer, which is connected to the building structure through the coating layer, and the carbon fiber has a terminal, so that the external circuit and the carbon fiber layer are connected to measure the current information in disguised form through other parameters. When the building structure is damaged, the conductive grid in the adhered carbon fiber layer is destroyed, causing the resistance to increase, so the building structure can be judged through this type of resistance detection circuit. On the other hand, the carbon fiber detection plate not only has good electrical conductivity, but also has good strength and rigidity, which can reinforce the building structure, extend the service life of the building structure, and do not change the shape and weight of the building structure.
[0108] Step 101: Calculate the current resistance information of the carbon fiber test plate glued to the building body according to the current current information and the preset circuit parameter information.
[0109] Circuit parameter information includes parameters of all components in the circuit, such as resistors, as well as information about the circuit's layout and connections. The current resistance information refers to the resistance on the carbon fiber test board. The calculation method is circuit analysis.
[0110] Step 102: generating resistance change curve information according to the current time information and the current resistance information.
[0111] The resistance change curve is a graph showing how the resistance value changes over time. The horizontal axis of the curve represents the current time, and the vertical axis represents the current resistance.
[0112] Step 103: Analyze the current resistance change rate information corresponding to the current time information according to the resistance change curve information.
[0113] The current resistance change rate information is the information about the instantaneous change of resistance at the current time information, which is essentially the information about the tangent slope of the intersection point on the curve corresponding to the current time information. The analysis method is the derivative function method.
[0114] Step 104: Analyze the current resistance change acceleration information based on the current resistance change rate information.
[0115] The current resistance change acceleration information is information about the instantaneous change in the current resistance change rate information. Essentially, it indicates the speed of the resistance change, i.e., whether a sudden change has occurred. The analysis method is the same as in step 103. A curve is plotted using the current resistance change rate information and the current time information as reference coordinates. The derivative function is then analyzed at the current time information position on the curve.
[0116] Step 105: Determine whether the current resistance change acceleration information is greater than a preset slow change threshold.
[0117] The slowly changing threshold value is acceleration information with a slowly increasing increase.
[0118] Step 1051: If it is greater than, output the structural destruction status information.
[0119] Structural damage status information indicates that the structure has been damaged. This information can be output as text. When the current resistance change acceleration exceeds the slow change threshold, it indicates that the resistance is increasing too quickly, indicating a damage phase.
[0120] Step 1052: If it is less than, output slight damage information.
[0121] Minor damage indicates only minor structural damage. If the value is less than 0.00, the carbon fiber test board is only slightly damaged and can still be used. During initial use, visually inspect the deformation of the carbon fiber test board and the adhesion between the board and the wall.
[0122] Reference Figure 3 , further comprising a method for continuing monitoring if the current resistance change acceleration information is greater than the slow change critical value, the method comprising:
[0123] Step 200: Obtain overall image information.
[0124] The overall image information is captured from the side of the carbon fiber inspection plate facing away from the building. The largest image is the exact size of the carbon fiber. This can be acquired using any visual method, such as a camera.
[0125] Step 201: Analyze the overall image information according to the preset building color information to determine the crack feature information of the carbon fiber detection plate.
[0126] Building color information refers to the surface color of the building being inspected. Crack signature information refers to cracks in the carbon fiber test plate. This information is generated when the carbon fiber test plate is partially broken by the building at different levels while still adhered to the building under shear stress. When the conductive mesh is damaged, a crack forms at the site, revealing the color of the building. Therefore, the presence and size of cracks can be determined based on the building's color.
[0127] Step 202: Determine left and right viewing angle information of a curve corresponding to the crack characteristic information according to the crack characteristic information.
[0128] The left and right viewing angles are the angles of view from either side of the crack, for example, 45° left and right. This is determined by analyzing the orientation of the crack's characteristic information in the image and then drawing a line at a 45° angle based on that orientation. The opposite angle is the viewing angle on one side.
[0129] Step 203: respectively obtain crack feature information using left and right viewing angle information to determine a viewing angle at which the crack feature information can be obtained, and define the viewing angle as crack viewing angle information.
[0130] The crack viewing angle information is information of a viewing angle at which crack characteristic information can be obtained.
[0131] Step 204: Determine low area information based on the crack feature information and the crack viewing angle information.
[0132] Low-area information refers to the area of the depression. Since cracks typically have one side higher than the other, the crack cannot be seen when viewed from the higher side at a 45-degree angle, while the crack can be seen from the lower side. Therefore, low-area information can be determined based on the crack viewing angle.
[0133] Step 205: Press the area corresponding to the low area information to obtain forward distance information and contact pressure information.
[0134] Advance distance information is the distance the contact head travels when pressing the carbon fiber test plate from the side facing away from the building. Contact pressure information is the pressure feedback when the contact head contacts the carbon fiber test plate from the side facing away from the building. This information is acquired using a pressure sensor.
[0135] Step 206: Determine whether the forward distance information increases when the contact pressure information obtained is greater than 0.
[0136] When the contact pressure information is greater than 0, it means that the contact head has touched the carbon fiber test plate. The purpose of the judgment is to determine whether there is a gap inside.
[0137] Step 2061: If it increases, the carbon fiber detection plate corresponding to the low area information is not pressed, and then the area corresponding to the low area information is re-coated with glue.
[0138] If it increases, it means that there are gaps inside and the carbon fiber test plate has been debonded. If it needs to be used again, it needs to be re-glued.
[0139] Step 2062: If not, continue to obtain current current information.
[0140] If it does not increase, it means that it can no longer move forward when it contacts the carbon fiber test plate, which means that there is an obstacle in front, that is, the existence of a building. If the carbon fiber test plate and the building are still bonded, it can continue to be used.
[0141] Reference Figure 4 , further comprising a method for determining low area information, the method comprising:
[0142] Step 300: Determine the area information on both sides according to the crack feature information and the overall image information.
[0143] The information of the two side regions is the information of the region where the entire image information is divided into two parts, and the crack feature information is the information of the region with the boundary line in the middle.
[0144] Step 301: Determine the total pressing direction information, the low area information to be verified, and the high area information according to the crack viewing angle information.
[0145] The overall pressing direction is from the crack feature information toward the low-region information. For example, if the left side of the image is the area where the low-region information is located, the order is from left to right. The low-region information to be verified is the information of the area on both sides where the low-region information is located. In other words, at this time, it has not yet been verified which areas of the low-region information to be verified are the areas of the low-region information to be verified. The high-region information is the information of the area that is half the height of the low-region information, that is, the area that is not the area of the low-region information to be verified.
[0146] Step 302: Determine the pressing direction information according to the crack characteristic information.
[0147] The pressing direction information is information about the order of pressing along the crack feature information, such as the direction from top to bottom from the perspective of the captured image.
[0148] Step 303: partition the low area information to be verified according to the total pressing direction information, the sub-pressing direction information and the preset single pressing area size information to obtain pressing unit area information and pressing sequence information.
[0149] The single pressing area size information is information about the area affected when the contact head is pressed down once. The pressing unit area information is information about the area corresponding to each unit pressed each time when pressing according to the pressing sequence information.
[0150] Step 304: Press the area corresponding to the high area information to obtain the verified forward distance information.
[0151] Check that the forward distance information is the distance value when the area corresponding to the high area information is pressed down. Theoretically, the distance information corresponding to the high area information is the information. Generally, the glue with high area information will not come off.
[0152] Step 305: Press the areas corresponding to all the pressing unit area information according to the pressing sequence information and obtain the forward distance information and the contact pressure information. The forward distance information is defined as the detected forward distance information, and the contact pressure information is defined as the detected contact pressure information.
[0153] The detected forward distance information is the forward distance information when the pressing unit region information is pressed. The detected contact pressure information is the contact pressure information when the pressing unit region information is pressed.
[0154] Step 306 : Increase the detected contact pressure information when the detected forward distance information does not increase.
[0155] Step 307 : When the detected contact pressure information increases but the detected forward distance information still does not increase, determine whether the detected forward distance information is greater than the verified forward distance information.
[0156] When the detected contact pressure information increases but the detected forward distance information still does not increase, it means that the carbon fiber has been pressed against the building body.
[0157] Step 3071: If it is equal, it is defined as the flattened unit area information.
[0158] The leveling unit area information is information of an area that is level with the high area information.
[0159] Step 3072: If it is greater than, it is defined as low unit area information.
[0160] If it is greater than, it means that the position is lower than the high area information at this time, and it is defined as low unit area information.
[0161] Step 308: After all pressed unit region information is judged, the low unit region information is integrated into low region information.
[0162] Reference Figure 5 The method of integrating the low unit area information into the low area information after judging all the pressed unit area information includes:
[0163] Step 400: Obtain current pre-detection unit area information.
[0164] The current pre-detection unit region information is the next pressing unit region information to be detected when detecting according to the pressing sequence information.
[0165] Step 401: Determine crack median information based on crack characteristic information.
[0166] The median position of the crack is the middle position of the crack in the longitudinal direction.
[0167] Step 402: Segment the pressing direction information according to the crack median information to obtain approaching segmented pressing direction information and distant segmented pressing direction information.
[0168] The approaching segmented pressing direction information is information about the pressing direction from the end away from the crack median information toward the crack median information. The away segmented pressing direction information is information about the pressing direction from the end close to the crack median information toward one end of the crack. If the pressing direction information is from top to bottom, the approaching segmented pressing direction information is above the crack median information, and the away segmented pressing direction information is below the crack median information.
[0169] Step 403: Determine total adjacent detected unit area information and sub-adjacent detected unit area information according to the current pre-detection unit area information, the total pressing direction information, and the sub-pressing direction information.
[0170] The total adjacent detected cell area information is the information about the cell area detected before the total direction information is pressed. If the lower area is on the left, the total adjacent detected cell area information is the adjacent cell area to the right of the current pre-detected cell area information. The sub-adjacent detected cell area information is the information about the cell area detected before the sub-direction information is pressed. If the sub-direction information is pressed from top to bottom, the sub-adjacent detected cell area information is the adjacent cell area above the current pre-detected cell area information.
[0171] Step 404: Determine whether the total adjacent detected unit region information is flat unit region information.
[0172] Due to the tearing characteristics of cracks, debonding generally starts from the crack and then gradually moves away from the crack. As the distance increases, the shear stress caused by the height difference at the crack decreases, so the scope of debonding becomes smaller and smaller, and eventually it will appear as a semicircular shape similar to an ellipse, with the crack being the short side of the ellipse.
[0173] Step 4041: If it is the leveling unit region information, the current pre-detection unit region information is directly determined as the leveling unit region information without pressing.
[0174] If the total adjacent detected unit area information is flat unit area information, it means that the boundary line of the low area information is located on one of its two sides or even farther and extends toward the side away from the total adjacent detected unit area information. Therefore, the boundary line will not extend toward the current pre-detection area. The current pre-detection area information and the total adjacent detected unit area information are located on the same side of the low area information, that is, they must be flat unit area information.
[0175] Step 4042: If it is not the flattened unit region information, determine whether the sub-pressing sequence corresponding to the sub-adjacent detected unit region information is the sequence corresponding to the away-segmented pressing direction information.
[0176] If not, it means that the total adjacent detected unit area information is low unit area information, and the extension direction of the low area information is uncertain, and the boundary line is also uncertain. Therefore, it is necessary to determine whether the sub-pressing order corresponding to the sub-adjacent detected unit area information is the order corresponding to the away segment pressing sub-direction information.
[0177] Step 4051: If the direction is not away from the segmented pressing direction information, a pressing judgment is performed on the current pre-detection area information.
[0178] If it is not in the direction of moving away, it means that the current pre-detection area information cannot be determined by dividing the adjacent detected unit area information, whether it is the flat unit area information or the low unit area information, and a press judgment is required.
[0179] Step 4052: If the direction is away from the segmented pressing direction information, then determine that the adjacent detected unit area information is flat unit area information.
[0180] Step 4061: If it is the leveling unit region information, the current pre-detection unit region information is directly determined as the leveling unit region information without pressing.
[0181] If the direction is away from the segmented pressing direction information, and the adjacent detected unit area information is the flat unit area information, it means that the boundary line of the low area information is located on the upper side of the adjacent detected unit area information, and the current pre-detection unit area information cannot be surrounded. The current pre-detection unit area information can be directly judged as the flat unit area information without pressing.
[0182] Step 4062: If it is not the flattened unit area information, perform a press judgment on the current pre-detection area information.
[0183] If not, it means that the boundary line of the low area information is located at the lower side of the adjacent detected unit area information, and it is impossible to directly determine whether it is the flat unit area information, and pressing judgment is required.
[0184] Reference Figure 6 : The method of re-gluing the area corresponding to the low area information includes:
[0185] Step 500: Determine reverse gluing sequence information according to the pressing sequence information and the low area information.
[0186] The reverse gluing order information is information of a gluing order that is opposite to the pressing order information and is within the low area information.
[0187] Step 501: Obtain the current glue coating unit area information.
[0188] The current gluing unit area information is the information of the unit area currently being glued.
[0189] Step 502: Determine the maximum forward distance information of the current gluing unit area information.
[0190] The maximum forward distance information is the distance pressed in the current glue application unit area information, which is actually obtained by accumulating the distance from the time when the contact pressure information is greater than 0. The purpose is to determine the thickness of the glue application space.
[0191] Step 503: Calculate unit glue quantity information according to the maximum forward distance information and the preset unit size information.
[0192] The unit size information is the size of the current glue unit area information. The unit glue quantity information is the amount of glue required to fill the glue space. The calculation method is to subtract the verification advance distance information from the maximum advance distance information and multiply it by the unit size information.
[0193] Step 504: Calculate the glue spraying speed information according to the unit glue amount information and the unit size information.
[0194] The glue spraying speed information is the flow rate of glue required to fill the glue quantity information of the unit when passing through the current glue unit area information. Here, it is set to pass through each area at a uniform speed.
[0195] Step 505: Insert the glue spraying tube from the crack into the area corresponding to the low area information between the carbon fiber test plate and the building body and move along the direction of the reverse glue coating sequence information. When the current unit is the current glue coating unit area information, glue is applied according to the glue spraying speed information.
[0196] Reference Figure 7 , also includes an auxiliary method for spraying glue, the method comprising:
[0197] Step 600: Determine low cell boundary region information and corresponding adjacent leveling cell region information according to the low region information and the leveling cell region information.
[0198] The low cell boundary region information is the low cell region information that is on the boundary line of the low cell region information or just on one side of the boundary line. The adjacent leveling cell region information is the leveling cell region information that is adjacent to the low cell boundary region information. It should be noted that the boundary line of the low cell region information must not fall within the leveling cell region information.
[0199] Step 601: Determine the glue spraying time information of the low unit boundary area information according to the reverse glue coating sequence information and the preset glue spraying tube movement speed information.
[0200] The glue hose movement speed information is the speed of the glue hose moving along the reverse glue application sequence information, and is set to a uniform speed here. The glue spraying time information is the time node of the glue spraying. Since the movement speed of the glue hose is fixed when applying glue along the reverse glue application sequence information, the glue spraying time of each low unit boundary area information is fixed.
[0201] Step 602: Calculate the softening time information according to the glue spraying time information and the preset softening time information.
[0202] The softening duration information is the time it takes for the adhesive layer to soften to the desired degree after heating the folded carbon fiber test plate from the side facing away from the building. The softening time information is the start time of softening the adhesive layer in the adjacent flattening unit area information. This is calculated by subtracting the softening duration information from the glue spraying time information.
[0203] Step 603: heating and softening the area corresponding to the adjacent flattening unit area information from the side of the carbon fiber test plate away from the building body at the softening time information.
[0204] The softened adhesive layer and the newly added glue are mutually soluble and do not delaminate, making the connection between the carbon fiber test board and the building body tighter.
[0205] Reference Figure 8 The method of moving the glue spraying tube in the direction of the reverse glue coating sequence information and applying glue according to the glue spraying speed information when the current unit is the current glue coating unit area information includes:
[0206] Step 700: Determine whether the maximum forward distance information is less than the preset glue spray hose diameter information.
[0207] The glue spraying hose diameter information is the outer diameter of the glue spraying hose. The purpose of the judgment is to determine whether the glue spraying hose can be inserted into the corresponding unit area for glue spraying.
[0208] Step 7001: If it is greater than, the area is sprayed with glue normally.
[0209] If it is greater than, it means that the glue spraying hose can be put into the corresponding unit area for glue spraying.
[0210] Step 7002: If it is less than, the low unit area information is defined as unreachable area information.
[0211] The "Cannot reach area" message indicates that the glue hose cannot enter the glue spraying area. If it is less than , it means that it cannot be inserted.
[0212] Step 701: Determine unreachable area information located in the same direction according to the total pressing direction information, and define the set corresponding to the unreachable area information as unreachable area group information.
[0213] The unreachable region group information is a collection of unreachable region information on the same straight line along the general pressing direction information, for example, unreachable region information on a horizontal straight line from left to right.
[0214] Step 702: Determine unreachable depth information according to the unreachable area group information.
[0215] The unreachable depth information is information about the depth of the unreachable region group information, and is determined by multiplying the number and the cell size information.
[0216] Step 703: performing a matching analysis based on the glue spraying force curve information and the unreachable depth information stored in the preset glue spraying database to determine the glue spraying force curve corresponding to the unreachable depth information, and defining the glue spraying force curve as the filling glue spraying force curve information.
[0217] The filling glue spraying force curve information is the curve information of the force change over time when the glue is sprayed along the general pressing direction. As the glue is continuously injected, the corresponding area will be continuously filled, and the unreachable depth information will continue to decrease, so the force will also continue to decrease, so the force is a curve. The database stores the mapping relationship between the glue spraying force curve information and the unreachable depth information. After the staff in this field set it according to the corresponding unit size information in the sealing area of different depths, they adjust the force to observe the glue spraying process and evenly fill the corresponding depth to record the appropriate force curve. When the system receives the corresponding unreachable depth information, it automatically searches for the corresponding glue spraying force curve from the database and outputs it with the corresponding filling glue spraying force curve information.
[0218] Step 704: After removing all unreachable area group information from the reverse gluing sequence information, arrange the order of the unreachable area group information after the removed reverse gluing sequence information and update the reverse gluing sequence information. The updated reverse gluing sequence information is defined as adjusted reverse gluing sequence information.
[0219] The purpose of adjusting the reverse glue coating order information here is to make the glue in the remaining areas first begin to solidify slightly to form glue spraying channels, thereby improving the efficiency of glue spraying.
[0220] Step 705: Move the glue spraying tube in the direction of adjusting the reverse glue coating sequence information and when the current unit is the current glue coating unit area information, glue is coated according to the glue spraying speed information; when the order corresponding to the area group information cannot be reached, glue is coated according to the filling glue spraying impact curve information at the end closest to the crack in the area corresponding to the area group information that cannot be reached.
