[0011] According to a preferred embodiment, the spatio-temporal domain fusion and noise filtering preprocessing includes the following steps: S11: Perform segmented processing on the three-dimensional deformation data through the sliding window algorithm, extract the extreme points, mutation points and periodic characteristics of the time series, and generate a time-domain parameter group including the stress change rate and the deformation frequency; S12: Based on the geometric topological relationship of the hexagonal array, map the discrete sensor data into a continuous spatial field, calculate the spatial gradient through the Laplace operator, and generate a spatial-domain parameter group including the stress distribution pattern and the strain gradient direction; S13: Adopt the wavelet transform algorithm with an adaptive threshold to decompose the time-domain parameter group and the spatial-domain parameter group, retain the low-frequency effective signals, filter out the high-frequency random noise, and generate the preprocessed data with enhanced features.

[0012] According to a preferred embodiment, the multi-scale tensor analysis includes the following steps: S21: Decompose the characteristic parameter group into three scales: macroscopic, mesoscopic, and microscopic; based on the spatial symmetry of the hexagonal array, map the decomposed parameters into a geometric coordinate system to form a tensor field distribution; S22: By analyzing the geometric characteristics of the tensor field, identify the stress concentration areas, the inflection points of the stress gradient change, and the stress distribution pattern; based on the topological neighborhood correlation rule, calculate the principal stress direction parameter of each area to obtain the principal stress direction parameter of the wall surface; S23: Analyze the shear characteristics of the tensor field, identify the shear strain concentration band, the strain gradient direction, and the strain distribution curvature; based on the topological neighborhood correlation rule, calculate the shear strain component parameter of each area to obtain the shear strain component parameter of the wall surface.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The device is provided with a placement groove on the support plate, and a storage bag storing magnetorheological fluid is arranged in the placement groove. The magnetorheological fluid has the characteristic of instantaneously changing from a liquid state to a solid state under the action of a magnetic field. When the main sensor and the strain sensor on the contact surface detect the deformation of the wall, the control module adjusts the current intensity of the electromagnetic coil according to the data processing result, thereby changing the viscosity of the magnetorheological fluid in the storage bag and realizing the real-time dynamic adjustment of the support strength.

[0015] 2. The design of the lifting assembly and the pushing part of the device further improves the flexibility and adaptability of reinforcement. The electric lifting rod can adjust the height of the pushing part to meet the reinforcement requirements of walls with different heights; the cooperation between the triangular clamping block on the pushing base and the clamping groove of the mounting seat, and the setting of the cooperation angle α (10° - 30°) can not only ensure the stable installation of the pushing part, but also facilitate disassembly and angle adjustment; the first electric cylinder drives the support plate to move, enabling the storage bag to closely fit the wall surface, ensuring the effective transmission of the support force of the magnetorheological fluid and realizing the all-round reinforcement of the wall.

[0016] 3. The strain sensors arranged in a hexagonal pattern and the central main sensor form an efficient monitoring network. Compared with the traditional single-point or regular grid layout, the hexagonal array can capture the stress distribution and deformation direction on the wall surface more accurately, providing rich and accurate data for the control module. At the same time, the stable structure composed of the stable gear, the locking sleeve and the second electric cylinder, combined with the lubrication design of the oil-absorbing cotton and the oil storage cavity, ensures the stable and reliable lifting operation of the device during long-term use, reduces mechanical wear, extends the service life, and provides continuous and stable guarantee for building repair and reinforcement.

[0019] The following further describes the implementation mode of the present invention in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0020] Embodiment: As Figures 1 to 12 shown, the present invention provides a reinforcement and protection device for building repair, including a base 11, a driving component 21 for moving the device, and a pressing part. The driving component 21 is installed at the bottom of the base 11. The driving component 21 can drive the device to move on the ground, enabling the device to conveniently reach the position of the wall to be reinforced and meeting the moving requirements of different construction scenarios. A lifting assembly is provided on the base 11, and this lifting assembly is used to adjust the height of the pressing part. The pressing part is installed at the top of the lifting assembly. Through the adjustment of the lifting assembly, the pressing part can move in the vertical direction, thereby adapting to walls of different heights and enabling the device to perform reinforcement operations on walls of different heights. The driving component 21 is installed at the bottom of the base 11, providing power support for the movement of the device and ensuring the stability and flexibility of the device movement. A support member is provided above the base 11, and the support member is located on one side of the pressing part, used to support and reinforce the wall.

[0021] The support member includes a support plate 301 and multiple groups of storage sacs 302, and a magnetorheological fluid is stored in the storage sacs 302. The support plate 301 is connected to one side of the pressing part. Under the action of the pressing part, the support plate 301 can be close to the wall. Multiple groups of placement grooves 303 are formed on one side of the support plate 301, and the multiple groups of placement grooves 303 are arranged to form a grid-like structure. This grid-like distribution enables the storage sacs 302 to be evenly distributed on the support plate 301. The storage sacs 302 are clamped in the placement grooves 303, which can play a role in fixing the storage sacs 302 and prevent them from displacing during the operation of the device. An electromagnetic coil 304 is wound around the storage sac 302. When the electromagnetic coil 304 is energized, a magnetic field will be generated. The magnetic field acts on the magnetorheological fluid in the storage sac 302, which can change the viscosity of the magnetorheological fluid, and then change the support strength of the support member, realizing the dynamic support and reinforcement of the wall.

[0022] A contact plate 305 is arranged on one side of the storage sac 302. One side of the contact plate 305 is the contact surface. The contact plate 305 contacts the wall through this contact surface, and transmits the support force of the support member to the wall. A main sensor 306 and multiple groups of strain sensors 307 are arranged on the contact surface. The main sensor 306 can be a displacement sensor, which can collect displacement signals of the wall in the vertical direction and other directions, and is used to characterize the overall settlement or expansion deformation of the wall. The main sensor 306 can be an LVDT (Linear Variable Differential Transformer) type displacement sensor of the R - Series. The multiple groups of strain sensors 307 can monitor the strain condition of the wall surface and obtain the strain data of the wall. These data can reflect the deformation trend and degree of the wall. The strain sensors 307 can be Honeywell SS200 series strain gauge sensors. The main sensor 306 and the strain sensors 307 transmit the collected data to the control module 22, providing a basis for the control module 22 to analyze the state of the wall and issue control instructions.

[0023] A main body housing 12 is arranged on the base 11. The main body housing 12 forms a main body cavity, which provides an installation space for the battery pack and the control module 22. The battery pack and the control module 22 are installed in the main body cavity. The battery pack is composed of multiple groups of batteries, which can store electric energy and provide power supply for each component of the device, such as the driving component 21, the electric lifting rod 23, the electromagnetic coil 304, etc., to ensure the normal operation of the device. The control module 22 is the control core of the device. It receives the data transmitted by the main sensor 306 and the strain sensors 307, analyzes and processes the data, and then controls the operation of components such as the driving component 21, the electric lifting rod 23, and the electromagnetic coil 304 according to the analysis results, realizing the automatic reinforcement operation of the device. The control module 22 can adopt a TM241CEC24T control module.

[0024] The lifting component is composed of a first sleeve 41, an electric lifting rod 23, and a second sleeve 13. The second sleeve 13 is provided on the base 11. The first sleeve 41 is inserted into the second sleeve 13, and the two are slidably connected to form a lifting cavity. This sleeve structure provides guidance and support for the height adjustment of the pressing part, enabling the first sleeve 41 to move smoothly up and down within the second sleeve 13, avoiding shaking or deviation.

[0025] The electric lifting rod 23 is located within the lifting cavity. Its bottom is connected to the second sleeve 13, and its top is connected to the first sleeve 41. The electric lifting rod 23 serves as the power source. Through its own telescopic movement, it drives the first sleeve 41 to slide within the second sleeve 13. When the electric lifting rod 23 extends, the first sleeve 41 moves upward along the second sleeve 13, thereby raising the height of the pressing part; when the electric lifting rod 23 shortens, the first sleeve 41 moves downward, lowering the height of the pressing part, thus realizing the adjustment of the height of the pressing part to meet the reinforcement requirements of walls at different heights.

[0026] As Figure 2 , Figure 3 , Figure 9 , Figure 10 shown, the pressing part includes a pressing base 51. On one side of the first sleeve 41, there is a mounting seat 42. On one side of the pressing base 51, there are multiple groups of triangular blocks 52. The inclined surface of the block 52 forms an angle α with the side surface of the pressing base 51, and the value range of α is between 10° and 30°. The mounting seat 42 is provided with multiple groups of slots 43 corresponding to the blocks 52. After the blocks 52 are inserted into the slots 43, they can play a preliminary positioning role for the pressing base 51, enabling the pressing base 51 to quickly find the corresponding position during installation. Subsequently, the pressing base 51 is connected to the mounting seat 42 through multiple groups of bolts. This connection method ensures that the pressing base 51 is firmly installed on the first sleeve 41. By forming an upward resistance, it restricts the vertical movement of the pressing base 51 and prevents it from loosening and falling off due to vibration or external force during the operation of the device. At the same time, the cooperation between the blocks 52 and the slots 43 and the setting of the angle α enable the pressing base 51 to rotate flexibly within a certain range when the angle needs to be adjusted to adapt to wall surfaces at different angles, facilitating the all-round reinforcement operation of the wall. When it is necessary to disassemble the pressing base 51, simply unscrew the bolts, and the blocks 52 can be taken out of the slots 43, which is convenient for the maintenance and component replacement of the device.

[0027] On one side of the pushing base 51, there are multiple groups of mounting sleeves 53, and a first electric cylinder 54 is installed inside the mounting sleeve 53. On one side of the support plate 301, a connecting plate 308 is provided, and the connecting plate 308 is connected to the shaft ends of multiple groups of first electric cylinders 54. When the first electric cylinder 54 works, it pushes the connecting plate 308 through telescopic movement, and then drives the support plate 301 to move. When it is necessary to reinforce the wall, the first electric cylinder 54 extends, pushing the support plate 301 towards the wall direction, so that the storage bladder 302 on the support plate 301 can contact the wall surface for subsequent support and reinforcement operations; when the reinforcement is completed or the position needs to be adjusted, the first electric cylinder 54 shortens, driving the support plate 301 to retract.

[0028] As Figure 2 , Figures 5 to 8 shown, there are two groups of support frames 14 arranged on the base 11, and these two groups of support frames 14 play a role in supporting and stabilizing the device. Both the first sleeve 41 and the second sleeve 13 are located between the two groups of support frames 14, and this layout enables the two groups of support frames 14 to effectively protect and support the first sleeve 41 and the second sleeve 13. On both sides of the first sleeve 41, there are stabilizing racks 61 provided, and on the support frame 14, there is a rotatable stabilizing gear 62, and the stabilizing gear 62 meshes with the stabilizing rack 61. When the first sleeve 41 moves up and down under the action of the electric lifting rod 23, the stabilizing rack 61 will move up and down accordingly. Since the stabilizing gear 62 meshes with the stabilizing rack 61, the stabilizing gear 62 will rotate under the drive of the stabilizing rack 61. This meshing relationship makes the up and down movement of the first sleeve 41 smoother and more stable.

[0029] On one side of the stabilizing gear 62, there is a rotating rod 63, and the rotating rod 63 rotates synchronously with the stabilizing gear 62. One end of the rotating rod 63 is provided with a locking part. A locking sleeve 64 is sleeved on the rotating rod 63 and is located within the locking part. Two groups of sliding grooves 65 are opened at both ends of the locking sleeve 64, and two groups of positioning holes 66 corresponding to the sliding grooves 65 are opened on the rotating rod 63. A positioning bolt 67 is inserted into the two groups of sliding grooves 65 at one end of the positioning hole 66 and the locking sleeve 64. Through this structure, the locking sleeve 64 can rotate around the positioning bolt 67 within a certain range. Specifically, the locking sleeve 64 can rotate within 50 degrees through the positioning bolt 67.

[0030] Multiple groups of first teeth 68 are provided on the locking sleeve 64, and these first teeth 68 are arranged to form a gear structure. Assembly plates 15 are provided on both sides of the support frame 14, and the assembly plates 15 are used to mount the second electric cylinder 16. The second electric cylinder 16 is mounted on the assembly plate 15, and a locking plate 17 is provided at the shaft end thereof. The locking plate 17 is arc-shaped and is adapted to the outer contour of the locking sleeve 64. Multiple groups of second teeth 18 are provided on the inner side of the locking plate 17, and these second teeth 18 form a rack structure. When the second electric cylinder 16 operates, it will push the locking plate 17 towards the locking sleeve 64, so that the second teeth 18 are clamped between two groups of first teeth 68, thereby realizing the locking of the locking sleeve 64, and further restricting the rotation of the stable gear 62, and fixing the first sleeve 41 at the current height.

[0031] Arc surfaces are provided on the tops of the first teeth 68 and the second teeth 18. When the tops of the first teeth 68 and the second teeth 18 come into contact, due to the existence of the arc surfaces, they will slide to one side when they come into contact. At the same time, in cooperation with the rotation of the locking sleeve 64, the first teeth 68 and the second teeth 18 can be engaged with each other. This structural design makes the meshing process between the teeth smoother, reduces the friction and wear between the teeth, and also facilitates the meshing and separation operations of the teeth.

[0032] An oil storage cavity 69 is formed in the stable gear 62, and a liquid inlet 71 is provided on the stable gear 62. Both ends of the liquid inlet 71 communicate with the oil storage cavity 69 and the outside respectively. The liquid inlet 71 is inclined and forms an angle β with the axis of the stable gear 62, and β is between 15° and 75°. Lubricating oil can be injected into the oil storage cavity 69 through the liquid inlet 71. The inclined liquid inlet 71 facilitates the injection of lubricating oil and also prevents the lubricating oil from flowing out of the liquid inlet 71 easily.

[0033] Limit grooves 72 are provided on the tooth surfaces of the stable gear 62, and oil-absorbing cotton 73 is clamped in the limit grooves 72. Multiple groups of oil delivery channels are formed in the stable gear 62, and the oil storage cavity 69 communicates with the limit grooves 72 through the oil delivery channels. The lubricating oil in the oil storage cavity 69 flows into the limit grooves 72 through the oil delivery channels and is absorbed by the oil-absorbing cotton 73. The oil-absorbing cotton 73 protrudes from the tooth surface of the stable gear 62 and contacts the tooth surface of the stable rack 61. When the stable gear 62 meshes and rotates with the stable rack 61, the oil-absorbing cotton 73 will apply the lubricating oil to the tooth surfaces of the stable gear 62 and the stable rack 61, playing a lubricating role, reducing the friction and wear when the gear and the rack mesh, and improving the service life and working stability of the device.

[0034] As Figure 2 、 Figure 4As shown, a first installation groove 309 and multiple groups of second installation grooves 310 are provided on the contact surface. These installation grooves provide fixed positions for the installation of sensors. The main sensor 306 is clamped in the first installation groove 309 and can be stably fixed on the contact surface, used to collect relevant data of the wall, such as the displacement change signal perpendicular to the wall surface, so as to reflect the overall settlement or expansion deformation of the wall. The strain sensors 307 are clamped in the second installation grooves 310. Multiple groups of strain sensors 307 are arranged in a hexagonal shape and are located at the center of the side lines of the hexagon, while the main sensor 306 is located at the center of the hexagon. Such a layout enables the sensors to obtain strain information on the wall surface from multiple directions and positions.

[0035] The strain sensors 307 are electrically connected to adjacent strain sensors 307, forming a data transmission network that can transmit the collected data to each other. Two groups of strain sensors 307 and the main sensor 306 are electrically connected to the control module 22 and transmit the collected data to the control module 22. After receiving these data, the control module 22 analyzes and processes them, and then judges the deformation state and degree of the wall, providing a decision-making basis for subsequent reinforcement operations.

[0036] A silicone protective layer 311 is provided on one side of the support plate 301. The main sensor 306 and multiple groups of strain sensors 307 are both located between the silicone protective layer 311 and the support plate 301 and are indirectly in contact with the wall through the silicone protective layer 311. The silicone protective layer 311 has a certain elasticity. When the device contacts the wall, it can play a buffering role to prevent the sensors from being damaged due to direct collision with the wall. At the same time, the silicone protective layer 311 can also play a certain protective role for the sensors, preventing the sensors from being affected by external factors such as dust and moisture, ensuring that the sensors can work stably for a long time and continuously provide accurate monitoring data for the device.

[0037] The battery pack is composed of multiple battery modules 24, providing power for the operation of the entire device. A battery box 19 is provided on the base 11. The battery box 19 is located in the main body cavity formed by the main body housing 12, and its function is to accommodate and fix the battery modules 24. Each battery module 24 is installed in the battery box 19, and a heat insulation plate is provided between adjacent battery modules 24. The heat insulation plate can block the heat generated during the operation of the battery modules 24, prevent the heat from accumulating inside the battery pack, avoid affecting the battery performance due to too high temperature, and even cause safety problems, ensuring the stable operation of the battery pack.

[0038] An installation bracket 25 is provided inside the main body cavity. The installation bracket 25 serves to support and fix the equipment box 26. The equipment box 26 is installed on the installation bracket 25, and the control module 22 is installed inside the equipment box 26. The equipment box 26 provides a protection space for the control module 22, which can reduce the interference of external factors on the control module 22, such as dust, moisture, etc., ensuring that the control module 22 can operate safely and stably, accurately receive and process the data transmitted by the sensors, and then control the operation of each component of the device.

[0039] An installation frame is provided on the base 11. The cross-section of the installation frame is stepped, and the main body housing 12 is clamped inside the installation frame. This structure makes the connection between the main body housing 12 and the base 11 more stable, capable of withstanding the vibration and external forces during the operation of the device. Multiple water storage tanks are provided inside the main body housing 12. The multiple water storage tanks communicate with each other and can store a certain amount of water. At the same time, multiple heat dissipation fins are also provided inside the main body housing 12. When the internal components of the device generate heat during operation, the heat is transferred to the main body housing 12. At this time, the water in the water storage tank absorbs heat through heat exchange, and the heat dissipation fins increase the contact area between the main body housing 12 and the external air, accelerating the speed of heat dissipation into the air, thereby reducing the internal temperature of the device, ensuring that components such as the battery pack and the control module 22 work in a suitable temperature environment, and extending the service life of the device.

[0040] Such as Figure 4 、 Figure 11 、 Figure 12 The wall adaptive reinforcement method of a reinforcement protection device for building repair shown in the figure is applied to the above-mentioned reinforcement protection device for building repair, and includes the following steps: S1: Obtain three-dimensional deformation data, perform spatio-temporal domain fusion and noise filtering preprocessing on the three-dimensional deformation data based on the tensor field dynamic reconstruction algorithm associated with the hexagonal topological neighborhood, and generate a characteristic parameter group including stress tensor parameters, strain gradient parameters, and deformation direction parameters; Specifically, the algorithm constructs a hexagonal topological structure to connect the discretely distributed sensor data points in space into a network with neighborhood association relationships. In this network, each node represents a sensor data, and its neighborhood nodes are arranged in a hexagonal array. This structure can more accurately reflect the anisotropic characteristics in the physical space and has higher accuracy in expressing curved surfaces and irregular boundaries compared to traditional rectangular grids.

[0041] During the tensor field dynamic reconstruction process, the algorithm first establishes a physical model based on the stress-strain relationship, converts the measurement values at each sensor node into tensor form. Then, by solving the partial differential equation of the tensor field and combining the constraint relationships between neighborhood nodes, the smooth reconstruction of the tensor field is achieved. The time dimension parameter is introduced in this process, making the reconstruction result able to reflect the dynamic evolution process of the deformation.

[0042] Furthermore, the algorithm uses the weighted least squares method to solve the tensor field equation, and the weight coefficient is dynamically adjusted according to the sensor distance, measurement accuracy, and time correlation. In the time dimension, the tensor field is predicted and updated through the Kalman filter algorithm to improve the system's response ability to rapidly changing deformations.

[0043] For example, when local shear deformation occurs in the wall, the hexagonal topological neighborhood correlation algorithm can accurately identify the boundary and direction of the deformed area by analyzing the tensor differences between adjacent sensor nodes. At the same time, combined with time series analysis, the development trend of the deformation can be predicted, providing a basis for early warning.

[0044] Meanwhile, the three-dimensional deformation data includes: Normal displacement data: The displacement change signal perpendicular to the wall surface generated by the contact surface of the contact plate 305 contacting the wall is collected by the main sensor 306, which is used to characterize the overall settlement or expansion deformation of the wall; the main sensor 306 uses a high-precision displacement sensor with a measurement accuracy of up to 0.01 mm, which can capture the minute vertical displacement changes of the wall in real time. During the data collection process, the sensor converts the displacement signal into an electrical signal and transmits it to the control module 22 after analog-to-digital conversion.

[0045] Tangential displacement data: The displacement change signal parallel to the wall surface generated by the relative sliding between the contact surface and the wall is collected by multiple groups of strain sensors 307, which is used to characterize the shear deformation or slip trend of the wall; the strain sensors 307 are distributed in a distributed manner, and each sensor is responsible for monitoring the tangential displacement of a specific area. Through the layout of the hexagonal array, the sensors can cover the entire monitoring area and provide displacement information from multiple angles. After data collection, the relative displacement between adjacent sensors is calculated through the differential algorithm to obtain the shear deformation information of the wall.

[0046] Angle change data: The inclination change signal generated by the change in the attitude of the contact surface in three-dimensional space is obtained through the collaborative data calculation of the main sensor 306 and the strain sensors 307, which is used to characterize the torsion or bending deformation of the wall. Both the main sensor 306 and the strain sensors 307 are built-in with angle measurement units. By fusing the angle data of multiple sensors and using the complementary filter algorithm to eliminate measurement errors, accurate angle change information is obtained. This information is of great significance for judging whether the wall has torsional or local bending deformation.

[0047] And the spatio-temporal domain fusion and noise filtering preprocessing includes the following steps: S11: Segment the three-dimensional deformation data through a sliding window algorithm, extract the extreme points, mutation points and periodic characteristics of the time series, and generate a time-domain parameter group containing the stress change rate and deformation frequency; the sliding window algorithm uses a time window with a fixed length to slide on the data sequence, and calculates the statistical characteristics of the data within the window each time it slides. For extreme point detection, the algorithm determines the position of the extreme point by comparing the relationship between the center value of the window and the adjacent values. Mutation point detection uses a threshold comparison method. When the data change rate within the window exceeds the set threshold, it is determined as a mutation point. Periodic characteristic extraction converts the time-domain data into frequency-domain data through Fourier transform, and identifies the main frequency components and their amplitudes.

[0048] S12: Based on the geometric topological relationship of the hexagonal array, map the discrete sensor data into a continuous spatial field, calculate the spatial gradient through the Laplace operator, and generate a spatial-domain parameter group containing the stress distribution pattern and strain gradient direction; this step first constructs a discrete Laplace operator for the hexagonal grid, and interpolates the discrete sensor data to the grid nodes by means of weighted averaging. Then, use the Laplace operator to calculate the second-order derivative of the spatial field to obtain the curvature information of the stress distribution. By analyzing the curvature direction, the main direction of the strain gradient is determined. In this process, Kriging interpolation method is used to process the missing data points to improve the accuracy of spatial field reconstruction.

[0049] S13: Use the wavelet transform algorithm with an adaptive threshold to decompose the time-domain parameter group and the spatial-domain parameter group, retain the low-frequency effective signals, filter out the high-frequency random noise, and generate preprocessed data with enhanced features. The wavelet transform algorithm selects the db4 wavelet basis function to decompose the data into multiple layers. The determination of the adaptive threshold adopts the Birge-Massart strategy, and dynamically adjusts the threshold according to the local characteristics of the signal. During the decomposition process, the high-frequency coefficients correspond to the noise components, which are set to zero through threshold processing; the low-frequency coefficients correspond to the effective signals, which are retained and reconstructed. The reconstructed signal not only retains the main features of the original data, but also effectively suppresses the interference of random noise, providing a high-quality data basis for subsequent feature parameter extraction.

[0050] S2: Based on the spatial symmetry of the hexagonal array, perform multi-scale tensor analysis on the feature parameter group through the tensor decomposition algorithm to obtain the principal stress direction parameter and shear strain component parameter of the wall surface; construct a dynamic weight allocation model based on the topological neighborhood association rule, and dynamically adjust the sensor weight coefficient according to the spatial position of the deformation area and the strain gradient parameter; Specifically, this step is based on the characteristic parameter group generated in S1, which includes stress tensor parameters, strain gradient parameters, and deformation direction parameters. Since the data in the characteristic parameter group spatially corresponds to the information collected by sensors arranged in a hexagonal array, the rotational symmetry and mirror symmetry of the hexagonal array provide a structured analysis framework for the tensor decomposition algorithm. The tensor decomposition algorithm can decompose the high-dimensional characteristic parameter group into a combination of multiple low-dimensional tensors, thereby separating the stress and strain characteristics at different scales.

[0051] Furthermore, the tensor decomposition algorithm adopts the Tucker decomposition method, which decomposes the original tensor into the product form of a core tensor and multiple factor matrices. The core tensor preserves the internal structure and mutual relationships of the data, while the factor matrices correspond to the basis vectors in different dimensions (such as spatial position, stress and strain type). Through this decomposition, tensor features at macroscopic, mesoscopic, and microscopic scales can be extracted from the complex characteristic parameter group. At the same time, the topological neighborhood correlation rule establishes the correlation between data based on the connection relationship between each sensor node in the hexagonal array and its six adjacent nodes, and is used for subsequent parameter calculation and weight assignment.

[0052] For example, when stress concentration occurs locally in the wall, the stress tensor parameters in the corresponding area of the characteristic parameter group will show abnormal values. Through Tucker decomposition, the tensor decomposition algorithm can locate specific sensor nodes and their neighborhoods at the microscopic scale, identify the range of the stress concentration area at the mesoscopic scale, and grasp the overall stress distribution trend of the entire wall at the macroscopic scale.

[0053] A more detailed multi-scale tensor analysis includes the following steps: S21: Decompose the characteristic parameter group into three scales: macroscopic, mesoscopic, and microscopic; based on the spatial symmetry of the hexagonal array, map the decomposed parameters into a geometric coordinate system to form a tensor field distribution; During specific operations, the macroscopic scale takes the entire wall as the analysis object, and aggregates the characteristic parameter group into a tensor reflecting the overall deformation trend; the mesoscopic scale divides the wall into multiple hexagonal grid areas, and each area corresponds to a set of parameters for analyzing local deformation characteristics; the microscopic scale focuses on a single sensor node and its neighborhood to capture subtle deformation changes. During the geometric coordinate system mapping process, taking the center of the hexagon as the coordinate origin, and using the side length and interior angle relationship of the hexagon, each parameter is accurately mapped to the corresponding spatial position, and finally a continuous tensor field distribution is formed to intuitively display the stress and strain state of the wall.

[0054] S22: By analyzing the geometric features of the tensor field, identify the stress concentration areas, the inflection points of stress gradient changes, and the stress distribution patterns; based on the topological neighborhood correlation rules, calculate the principal stress direction parameters of each area to obtain the principal stress direction parameters of the wall surface. In the tensor field, the stress concentration area is manifested as the area where the tensor value is significantly higher than the neighborhood, which can be initially identified by setting a threshold. The inflection point of stress gradient change is determined by calculating the first derivative of the tensor field and finding the position where the derivative change rate is the largest. The stress distribution pattern can be visually observed by visualizing the contour lines or streamlines of the tensor field. Based on the topological neighborhood correlation rules, for each area, considering the stress tensor information of its six neighborhood nodes, a weighted average method is used to calculate the principal stress direction. The weights are determined according to the distance between nodes and the difference in strain gradients. The closer the distance and the smaller the difference in strain gradients between nodes, the higher the weight, so as to accurately calculate the principal stress direction parameters of each area, and then obtain the principal stress direction parameters of the entire wall surface.

[0055] S23: Analyze the shear characteristics of the tensor field, identify the shear strain concentration zones, the strain gradient directions, and the strain distribution curvatures; based on the topological neighborhood correlation rules, calculate the shear strain component parameters of each area to obtain the shear strain component parameters of the wall surface.

[0056] The shear characteristics of the tensor field are reflected by analyzing the off-diagonal elements of the strain tensor. The shear strain concentration zone is manifested as the area where the off-diagonal element values are large and continuous. The strain gradient direction is determined by calculating the gradient vector of the shear strain tensor, and the direction of this vector is the strain gradient direction. The strain distribution curvature is obtained by calculating the change rate of the gradient vector. Similarly, based on the topological neighborhood correlation rules, combined with the shear strain information of each area and its neighborhood nodes, a weighted method similar to the calculation of the principal stress direction is used to calculate the shear strain component parameters of each area. Through the calculation of all areas, the shear strain component parameters of the entire wall surface are finally obtained, providing key data support for subsequent reinforcement decisions.

[0057] Based on the parameters obtained from the above multi-scale tensor analysis, construct a dynamic weight allocation model. This model takes the spatial position of the deformed area and the strain gradient parameters as inputs. When the strain gradient of a certain area is large, it indicates that the deformation of this area is relatively severe. At this time, increase the weight coefficient of the corresponding sensor in this area, so that the control module pays more attention to the data in this area when making decisions; on the contrary, for the area with a small strain gradient, reduce its sensor weight coefficient. By dynamically adjusting the sensor weight coefficients, improve the response accuracy of the device to wall deformation and the reinforcement effect.

[0058] S3: Based on the preset thresholds of the principal stress direction parameters and the shear strain component parameters, when the characteristic parameter group exceeds the preset threshold, perform the partition viscosity regulation operation of the magnetorheological fluid through the gradient magnetic field regulation algorithm.

[0059] Specifically, this step is based on the principal stress direction parameter and shear strain component parameter obtained in S2, and corresponding safety thresholds are preset in the control module 22 in advance. These thresholds are determined according to the mechanical properties of building materials, wall design standards, and engineering experience, corresponding to the safety critical values of the principal stress direction parameter and shear strain component parameter respectively. When the stress tensor parameter, strain gradient parameter, etc. in the characteristic parameter group generated in S1 are analyzed and it is concluded that the principal stress direction parameter or shear strain component parameter exceeds the preset threshold, it indicates that there is a high risk of damage in the corresponding area of the wall and reinforcement intervention is required.

[0060] Furthermore, the core of the gradient magnetic field regulation algorithm lies in precisely controlling the magnetic field strength and direction generated by the electromagnetic coil 304 according to the stress and strain states of different regions, and then adjusting the viscosity of the magnetorheological fluid in the storage bladder 302. The algorithm first divides the wall surface into grid regions corresponding to the layout of the storage bladder 302, and each region corresponds to a group of electromagnetic coils 304. For each grid region, the algorithm determines the action direction of the magnetic field according to the principal stress direction parameter of the region - making the magnetic field direction form a specific angle (usually 90° to maximize the curing effect of the magnetorheological fluid) with the principal stress direction; determines the magnetic field strength according to the magnitude of the shear strain component parameter - the larger the shear strain component parameter, the larger the current of the corresponding electromagnetic coil 304 and the stronger the generated magnetic field strength.

[0061] The algorithm uses a PID (Proportional-Integral-Derivative) control strategy to achieve dynamic regulation of the magnetic field strength. The proportional link quickly responds according to the deviation between the current parameter and the threshold, and outputs the initial magnetic field strength adjustment amount; the integral link accumulates the historical deviation to eliminate the steady-state error and ensure that the magnetic field strength finally stabilizes at the target value; the derivative link predicts the trend according to the deviation change rate and adjusts the magnetic field strength in advance to avoid overshoot during the adjustment process. At the same time, considering the correlation of stress and strain in adjacent grid regions, the algorithm introduces a neighborhood coupling coefficient to perform smooth transition processing on the magnetic field strength of adjacent regions to prevent uneven curing of the magnetorheological fluid caused by sudden changes in the magnetic field strength.

[0062] For example, when it is detected that the principal stress direction in a certain area of the wall is horizontally to the right and the shear strain component parameter exceeds 120% of the preset threshold, the control module 22 triggers the gradient magnetic field regulation algorithm. The algorithm first determines that the magnetic field direction of the electromagnetic coil 304 corresponding to this area is the vertical direction, and then calculates according to the PID control strategy that the current of this electromagnetic coil 304 needs to be increased to 1.5 times the rated current to generate a high-intensity magnetic field. At the same time, for the electromagnetic coils 304 adjacent to this area, the algorithm appropriately adjusts the current according to the neighborhood coupling coefficient (such as increasing to 1.2 times the rated current) to make the viscosity of the magnetorheological fluid in the adjacent area form a gradual transition. Under the action of the magnetic field, the magnetorheological fluid in the corresponding storage bladder 302 quickly changes from a liquid state to a semi-solid state, providing additional support for the wall to offset excessive stress and strain.

[0063] Through the zoning viscosity regulation operation of the gradient magnetic field regulation algorithm, the device can achieve precise reinforcement of the high-risk areas of the wall, dynamically adjust the mechanical properties of the magnetorheological fluid according to the actual stress state, while ensuring the reinforcement effect, avoiding over-reinforcement of the entire wall, and improving the material utilization efficiency and reinforcement economy.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
