Description

Technical Field

[0001] The invention relates to the technical field of building monitoring, and in particular to a method for visually monitoring building structure safety. Background Art

[0002] Building structure safety monitoring is an important part of ensuring the long-term stability and safe operation of buildings. In recent years, sensor technology has made significant progress, providing a reliable hardware foundation for building structure safety monitoring. By installing various types of sensors in the building structure, the physical and chemical parameters of the structure can be monitored in real time. These sensors have high sensitivity, high precision and long-term stability, and can accurately reflect the state changes of the building structure. With the rapid development of big data technology, data acquisition and processing technology has been greatly improved. The building structure safety monitoring system needs to process, analyze, store and analyze the data collected by the sensors in real time and efficiently.

[0003] However, current existing technologies often only focus on the stress conditions in a single direction and ignore the overall stress state of the structure in three-dimensional space, which leads to an incomplete and inaccurate assessment of the structural safety status. The sensor technology used therein cannot meet the needs of real-time monitoring if the data processing and analysis are not timely. In addition, existing technologies often only provide simple data reports and charts, lacking intuitive visual displays, which makes it difficult for non-professionals to understand and apply the monitoring results. In addition, existing technologies often ignore the feedback and adjustment effects of monitoring results on the structural state, lack a cyclic influence mechanism, and make it impossible to effectively use the monitoring results to optimize structural design and reinforcement measures.

[0073] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0074] Regarding this visual monitoring method for building structure safety, it is different from the existing building structure monitoring method. The existing building structure monitoring method ignores the overall stress state of the structure in three-dimensional space and lacks intuitive visualization. It also ignores the feedback and adjustment effect of the monitoring results on the structural state and lacks a cyclic influence mechanism. This algorithm unit achieves beneficial effects in terms of comprehensiveness and accuracy, real-time and dynamics, intuitiveness and ease of understanding by real-time monitoring and evaluation of the three-dimensional state changes of the building structure, providing a more comprehensive, accurate, real-time and intuitive means for the safety monitoring of the building structure.

[0075] For example, see Figures 1 to 4 ,This implementation provides a building structure safety visual monitoring method, including a data acquisition module, a data processing module, a visual analysis module, and a control and adjustment module;

[0076] The specific implementation steps are as follows:

[0077] Step S1: Using the data acquisition module, collect the force and displacement of the current monitoring point in the building structure in the three directions of X, Y, and Z;

[0078] Step S2: using the data processing module, sequentially calculate and output the stress value X of the monitoring point, and the displacement deformation and safety status assessment value under stress in three directions of X, Y, and Z;

[0079] The data processing module includes a unit that reflects the stress distribution of the building structure under stress, a unit that describes the deformation behavior of the structure in all directions during stress, and a unit that evaluates the safety status of the building structure.

[0080] Step S3: Based on the safety status assessment values ​​under stress in the three directions of X, Y, and Z, and using the visualization analysis module, the monitoring analysis and adjustment measures in the three directions of X, Y, and Z are visualized;

[0081] Step S4: Using the control and adjustment module to control and adjust the building structure;

[0082] The equipment used in the data acquisition module includes strain gauges, displacement sensors, and data acquisition instruments;

[0083] The equipment used in the data processing module includes computers and data processing software;

[0084] The equipment used in the visual analysis module includes visual analysis software;

[0085] The devices used in the control and adjustment module include controllers and actuators.

[0086] In this embodiment, the system cooperates with three algorithm units and combines X, W x / W y / W z and R x / R y / R z The three types of calculation results together constitute the core part of the visual monitoring method for building structure safety. Specifically, X is the stress value of the monitoring point, which can more accurately reflect the stress distribution of the building structure under stress, which is crucial for evaluating the stability and safety of the structure, because too high stress values ​​will lead to structural damage and failure. x is the displacement deformation under stress in the X direction, W y is the displacement deformation under stress in the Y direction, W z is the displacement deformation under stress in the Z direction. This value can more accurately describe the deformation behavior of the structure during the stress process. The displacement deformation is one of the important indicators for evaluating the safety of the structure because it directly reflects the shape change of the structure under stress. x is the safety status assessment value under X-direction stress, R y is the safety status assessment value under Y-direction stress, R z is the safety status assessment value under Z-direction stress, which can comprehensively assess the three-dimensional safety status of the building structure and is expressed in percentage. x / R y / R z The calculation results can also affect the feedback to X and W x / W y / W z The calculation of R makes the three algorithms of this system have significant beneficial effects in the visual monitoring method of building structure safety. x / R y / R z For X, W x / W y / W zThe cyclic impact mechanism further enhances the practicality and effectiveness of the monitoring method. These three algorithms and the formed mechanism realize real-time monitoring and visual analysis of the safety status of the building structure. This method not only improves the accuracy and real-time performance of monitoring, but also provides strong support for the maintenance and management of the building structure.

[0087] See also Figures 1 to 4 , the calculation formula of the unit reflecting the stress distribution of the building structure under the stress state is as follows:

[0088] X=SQRT((L x 2 +L y 2 +L z 2 ) / LM)-Q / 10;

[0089] in:

[0090] X is the stress value at the monitoring point;

[0091] L x is the force value in the X direction;

[0092] L y is the force value in the Y direction;

[0093] L z is the force value in the Z direction;

[0094] X-direction force value L x , Y direction force value L y , Z direction force value L z Respectively reflect the stress conditions of the current monitoring point on the building structure in the three directions of X, Y, and Z;

[0095] LM is the force-bearing area;

[0096] Q is the distance value, which represents the distance between the current monitoring point on the building structure and the supporting point of the building structure.

[0097] In this embodiment: First, in this algorithm unit, "((L x 2 +L y 2 +L z 2The calculation part of "(LM) / LM)" calculates the ratio of the sum of the squares of the forces on the structural monitoring point in the three directions of X, Y, and Z to the force area LM, that is, the comprehensive stress. It reflects the force conditions of the current monitoring point in all directions and is an important indicator for evaluating the strength and safety of the structure. As the core calculation part of the unit that reflects the stress distribution of the building structure under the force state, it directly determines the size of the stress value X of the monitoring point, which in turn affects the subsequent displacement deformation calculation and safety status assessment;

[0098] The "Q / 10" calculation part takes into account the distance Q from the current monitoring point to the support of the building structure, and corrects it by dividing it by 10. This correction is to adjust the sensitivity of the stress value X of the monitoring point to the distance, so that the calculation result is more in line with the actual situation. As a correction item in the stress calculation, it and other calculation parts jointly determine the final result of the stress value X of the monitoring point. By adjusting this correction item, it can simulate the different stress distribution conditions of different locations due to the distance from the support.

[0099] This algorithm reflects the stress distribution of the building structure under stress by the X-direction force value L in the unit. x , Y direction force value L y , Z direction force value L z They represent the forces on the building structure in the three directions of X, Y, and Z, which fully considers the forces on the building structure in three-dimensional space. Through the calculation of these three forces, the stress distribution state of the structure can be fully reflected, avoiding the limitation of forces in a single direction.

[0100] The unit that reflects the stress distribution of the building structure under stress state introduces the distance value Q for correction, which reflects the relationship between the stress distribution and the position of the building structure. At a position far away from the support, the stress value will decrease as the distance increases. Therefore, by introducing the distance value Q for correction, the stress value of each point of the building structure can be calculated more accurately.

[0101] The force area LM is one of the key parameters for calculating stress, which determines the force per unit area. At the same time, the distance value Q is also an important factor affecting the stress distribution, which reflects the relative position relationship between each point of the building structure and the support point.

[0102] In addition, the calculation results of the unit that reflects the stress distribution of the building structure under stress state provide an accurate stress data basis for subsequent displacement deformation calculation and safety status assessment. Through visualization technology, the stress distribution state can be displayed in a graphical way, making the monitoring results more intuitive and easy to understand.

[0103] See also Figures 1 to 4 , the calculation formula for the unit describing the deformation behavior of the structure in each direction during the stress process is as follows:

[0104] W x =X×E((L x / LM)+SQRT(X));

[0105] W y =X×E((L y / LM)+SQRT(X));

[0106] W z =X×E((L z / LM)+SQRT(X));

[0107] in:

[0108] W x is the displacement deformation under stress in the X direction;

[0109] W y is the displacement deformation under stress in the Y direction;

[0110] W z is the displacement deformation under stress in the Z direction;

[0111] Displacement deformation under stress in X direction W x , displacement deformation under Y direction stress W y , displacement deformation under Z-direction stress W z Respectively reflect the displacement deformation of the building structure under the influence of forces in the three directions of X, Y, and Z at the current monitoring point.

[0112] E is the elastic modulus of the material.

[0113] In this embodiment, the "X×E" calculation part first calculates the product of the stress value X of the monitoring point and the elastic modulus E of the material, which reflects the elastic deformation capacity of the material under stress. This is the basis for displacement deformation calculation. As the core part of displacement deformation calculation, it directly determines the displacement deformation amount W under stress in the X direction. x , displacement deformation under Y direction stress W y , displacement deformation under Z-direction stress W z The basic value of can be combined with other parts to calculate the actual displacement of the building structure under the force in different directions. This calculation part may be to consider the force value L in the X direction. x , Y direction force value L y , Z direction force value L z The influence of displacement deformation is analyzed, and the force bearing area LM and the stress value X of the monitoring point are introduced for correction;

[0114] This algorithm reflects the nonlinear effect of stress on displacement deformation by displaying the square root of stress in the unit describing the deformation behavior of the structure in each direction during the stress process. This nonlinear effect consideration enables the unit describing the deformation behavior of the structure in each direction during the stress process to more accurately describe the deformation behavior of the structure during the stress process.

[0115] The unit describes the deformation behavior of the structure in each direction during the stress process by real-time monitoring the stress value X at the monitoring point and the force value L in the X direction. x , Y direction force value L y , Z direction force value L z , can calculate the displacement deformation W under X-direction stress in real time x , displacement deformation under Y direction stress W y , displacement deformation under Z-direction stress W z ,This real-time feature makes it possible for dynamic monitoring of the structure, making the monitoring results more timely and effective;

[0116] The elastic modulus E of the material is an important parameter reflecting the rigidity of the material, which determines the degree of deformation of the structure when subjected to force. At the same time, the stress value X at the monitoring point and the force value L in the X direction x , Y direction force value L y , Z direction force value L z It is also a key factor affecting the displacement and deformation;

[0117] Displacement and deformation is one of the important indicators for evaluating structural safety. By calculating the deformation behavior units in various directions of the structure during the stress process, the displacement and deformation of the building structure under the influence of various directions can be obtained, providing key data for subsequent safety status assessment.

[0118] See also Figures 1 to 4 , the calculation formula for evaluating the safety status unit of the building structure is as follows:

[0119] R x =[(W x，max -W x ) / W x，max ]×100-(X / X max )×SQRT(Q / Q max );

[0120] R y =[(W y，max -W y ) / W y，max ]×100-(X / X max )×SQRT(Q / Q max );

[0121] R z =[(W z，max -Wz ) / W z，max ]×100-(X / X max )×SQRT(Q / Q max );

[0122] in:

[0123] R x is the safety status assessment value under X-direction stress;

[0124] R y is the safety status assessment value under stress in the Y direction;

[0125] R z is the safety status assessment value under Z-direction stress;

[0126] Safety status assessment value R under X-direction stress x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z Respectively reflect the safety status assessment of the building structure under the influence of forces on the current monitoring point in the three directions of X, Y, and Z;

[0127] W x，max is the maximum displacement deformation under stress in the X direction;

[0128] W y，max is the maximum displacement deformation under stress in the Y direction;

[0129] W z，max is the maximum displacement deformation under stress in the Z direction;

[0130] X max is the maximum stress value;

[0131] Q max is the maximum distance value;

[0132] The maximum displacement deformation under X-direction stress W x，max , Maximum displacement deformation under Y direction stress W y，max and the maximum displacement deformation under Z-direction stress W z，max It reflects the maximum displacement deformation of the current monitoring point on the building structure under the maximum stress in the three directions of X, Y, and Z at the beginning of the building design;

[0133] Maximum stress value X max Reflects the maximum stress that the current monitoring point on the building structure can withstand in the three directions of X, Y, and Z at the beginning of the building design;

[0134] Maximum distance value Q maxIt reflects the distance between the current monitoring point on the building structure and the supporting point of the building structure at the beginning of the building design.

[0135] In this embodiment, the algorithm unit first "W x，max -W x The calculation part calculates the maximum displacement deformation W under X-direction stress. x，max and displacement deformation W under X-direction stress x It reflects the safety margin of displacement deformation of the building structure under the influence of the X direction. y，max -W y "Calculation part and "W z，max -W z The calculation part is the same as "W x，max -W x The calculation part is the same, and as an important part of the safety status assessment, it directly determines the safety status assessment value R of the displacement deformation part under the stress in the X direction. x By calculating this difference, the safety of the structure in terms of displacement and deformation can be evaluated;

[0136] “(X / X max )×SQRT(Q / Q max )” calculation part calculates the maximum stress value X max The ratio of the stress value X to the actual monitoring point, taking into account the maximum distance value Q max The ratio of the distance to the actual distance value Q is corrected, which reflects the safety margin of the building structure in terms of stress and the impact of the relative size on safety. As another important part of the safety status assessment, it determines the safety status assessment value R under the stress in the X direction together with other parts. x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z The final result is that by calculating this ratio and introducing the correction term, the safety of the structure in terms of stress and displacement deformation can be fully evaluated;

[0137] This algorithm evaluates the safety status of building structures by taking displacement deformation and stress into consideration. x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z To comprehensively evaluate the safety of the structure, this comprehensive evaluation method avoids the limitations of a single indicator and improves the accuracy and reliability of the evaluation results;

[0138] Result value of the unit for evaluating the safety status of the building structure Safety status evaluation value R under stress in the X direction x, Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z Expressed in percentage form, the monitoring results are more intuitive and easy to understand, and the safety status of the structure can be judged intuitively;

[0139] Maximum stress value X max and displacement deformation W under X-direction stress x , displacement deformation under Y direction stress W y , displacement deformation under Z-direction stress W z It is an important criterion for evaluating the safety of a structure. It determines the allowable deformation range and stress level of the structure when it is subjected to stress. At the same time, the distance value Q and the maximum distance value Q of the structure max It is also an important factor affecting the safety status assessment;

[0140] Result value of the unit for evaluating the safety status of the building structure Safety status evaluation value R under stress in the X direction x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z It can be used as a feedback signal to guide the dynamic adjustment of the structure. By real-time monitoring and evaluating the safety status of the structure, adjusting the stress conditions and taking reinforcement measures based on the evaluation results, it can achieve dynamic optimization and preventive maintenance of the structure.

[0141] For example 2, please refer to Figures 1 to 4 , based on the safety status assessment value R under X-direction stress x , Safety status assessment value R under Y direction stress y And the safety status assessment value R under Z-direction stress z The separate monitoring and analysis on the line chart are as follows:

[0142] Safety status assessment value R under X-direction stress x

[0143] If the safety state assessment value R under the stress in the X direction x If there is an upward trend on the line graph, it means that the safety status of the structure in the X direction has improved;

[0144] If the safety state assessment value R under the stress in the X direction x If the line graph shows a downward trend, it means that the load-bearing capacity of the structure is gradually approaching / exceeding it, and intervention measures should be taken immediately;

[0145] Safety status assessment value R under Y-direction stress y

[0146] If the safety state assessment value R under the Y direction stress yIf there is an upward trend on the line graph, it means that the safety status of the structure in the Y direction has improved;

[0147] If the safety state assessment value R under the Y direction stress y If the linear graph shows a downward trend, it means that the force adjustment measures are insufficient and the adjustment measures should be strengthened;

[0148] Safety status assessment value R under Z-direction stress z

[0149] If the safety state assessment value R under Z-direction stress z An upward trend on the line graph indicates that the safety status of the structure in the Z direction has improved;

[0150] If the safety state assessment value R under Z-direction stress z If there is a downward trend on the line graph, it means that there are problems with the foundation and vertical support structure, and maintenance measures should be taken for the foundation and vertical support structure;

[0151] Any monitoring method must calculate the displacement deformation and safety status evaluation separately according to the force influence of the current monitoring point in the three directions of X, Y, and Z in the unit describing the deformation behavior of the structure in each direction during the force process and the unit evaluating the safety status of the building structure, and observe the changing trend of the safety status under the influence of the force in the three directions of X, Y, and Z in combination with the line graph.

[0152] In this embodiment, by real-time monitoring and evaluation of the safety status of the structure and adjusting the stress conditions according to the evaluation results, the three-dimensional dynamic optimization of the building structure can be achieved. This dynamic optimization method can improve the stability and safety of the structure and extend the service life of the structure. Before the building structure has safety hazards, potential safety problems can be prevented by adjusting the stress conditions, thereby avoiding damage to the structure due to uneven stress. By dynamically adjusting and optimizing the structural state, unnecessary maintenance and reinforcement costs can be reduced. At the same time, this cyclic influence mechanism can also improve the overall performance and economic benefits of the structure.

[0153] It is worth noting that the line graph uses the X-axis to represent time, and the Y-axis represents the safety state assessment value R under the stress in the X direction. x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z , which can intuitively display the safety status assessment value R under X-direction stress x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress zThis visualization method can quickly capture the changes in the safety status of the building structure and respond in time. In addition, since the line chart can update data in real time, it can also reflect the real-time changes in the safety status of the structure and provide timely and accurate information support for decision-making;

[0154] By monitoring and analyzing the forces in the three directions of X, Y, and Z, the line graph can accurately display the safety status assessment value R under the stress in the X direction. x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z The changing trend under different stress states, this accuracy not only helps to accurately judge the safety status of the structure, but also provides a reliable basis for subsequent adjustment measures. At the same time, since the line chart is generated based on actual monitoring data, it has high reliability and can ensure the accuracy and credibility of the monitoring results;

[0155] The line graph analysis covers the stress conditions in the three directions of X, Y, and Z, which helps to fully understand the stress state and safety state of the building structure, and by comparing the safety state assessment value R under the X-direction stress in different directions x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z The trend of changes can more systematically analyze the safety issues of the structure, so as to formulate more comprehensive and effective adjustment measures. In addition, the line graph can also show the safety status assessment value R under the stress in the X direction. x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z The changes in different time periods can help to gain a deeper understanding of the long-term safety performance of the structure;

[0156] Line chart analysis can not only reflect the current safety status of the structure, but also predict the future safety status through trends. When the safety status assessment value R under X-direction stress x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z When the downward trend is present, the potential safety hazards caused by forces in different directions of the building structure can be predicted and intervention measures can be taken in advance. This predictability helps reduce the risk of structural safety accidents and improve the safety and stability of the structure.

[0157] In summary, the unit reflecting the stress distribution of the building structure under stress, the unit describing the deformation behavior of the structure in each direction during stress, and the unit evaluating the safety state of the building structure and their parameters have significant beneficial effects in the visual monitoring method for building structure safety. The cyclic influence mechanism of the unit evaluating the safety state of the building structure on the unit reflecting the stress distribution of the building structure under stress further enhances the practicality and effectiveness of the monitoring method. These formulas and mechanisms together constitute the core part of the visual monitoring method for building structure safety, providing a strong guarantee for the long-term stable operation of the structure. The safety state assessment value R under the stress in the X direction under stress in the three directions of X, Y, and Z is analyzed by combining the line graph. x , Safety status assessment value R under Y direction stress y , safety status assessment value R under Z-direction stress z Changing trends can bring beneficial effects in terms of intuitiveness, accuracy, comprehensiveness, guidance and predictiveness. This approach not only helps to timely discover and deal with structural safety issues, but also provides strong support for structural maintenance and management. In practical applications, full use of the advantages of line graph analysis can provide more scientific and effective means for safety monitoring and management of building structures.
