[0007] Further, the feature output unit determines a first deformation path of the first connection object based on the obtained three-dimensional position data of the first reference point and the preset first measuring point relative to the leveling base, and determines a second deformation path of the second connection object based on the obtained three-dimensional position data of the second reference point and the preset second measuring point relative to the leveling base, wherein the deformation path is formed according to the change of the position coordinates of the corresponding measuring point relative to the corresponding reference point.

[0008] Furthermore, the relative deformation path is determined by the three-dimensional position coordinates of the midpoint between the first reference point and the second reference point within a monitoring period and the direction vector determined by the first measurement point and the second measurement point.

[0009] Furthermore, the integrated measurement platform determines the time-series relative deformation amount of the corresponding connection feature according to the displacement amount of the midpoint and the direction vector, wherein the time-series relative deformation amount is a vector.

[0010] Further, the relative position change trend of the dimension measurement terminal includes a plane position change direction and a change angle; The integrated measurement platform is also used to determine the relative position change trend of the dimension measurement terminal according to the average plane position change direction and average change angle of the reference plane determined based on the position data of any three dimension measurement terminals among the dimension measurement terminals.

[0011] Furthermore, the matching verification module determines the external interference vector of the connection feature according to the plane position change direction and change angle corresponding to the relative position change trend.

[0012] Furthermore, the matching verification module determines whether to correct the temporal relative deformation amount of the corresponding connection feature according to the matching relationship between the single deformation path of the connection feature of the single modeling surface and the external interference vector, wherein: If any deformation path of the connection features of a single modeling surface matches the external interference vector, it is determined that the temporal relative deformation amount of the corresponding connection feature needs to be corrected.

[0013] Furthermore, the correction output module determines the design dimension correction value of the modeling surface according to the corrected relative deformation amount of the connection feature in time sequence, wherein: The correction output module determines the design dimension correction value of the modeling surface according to the time-series relative deformation amount of the connection feature before and after correction to form a dimension correction range and a correction coefficient, and determines the correction influence coefficient according to the building position of the modeling surface and the correction coefficient to determine the design dimension correction value of the modeling surface.

[0016] Furthermore, the present invention determines the time-series relative deformation of a single connection feature based on the relative size data of each single modeling surface, and determines the relative position change trend of the size measurement terminal based on the position data of each size measurement terminal, effectively utilizing the different position data of the connection features to characterize the connection characteristics of the connection objects, thereby effectively improving the detection accuracy of building inspections.

[0017] Furthermore, the present invention determines the relative position change trend of the dimension measurement terminal based on the average plane position change direction and the average change angle of the reference plane determined by the position data of any three dimension measurement terminals among the dimension measurement terminals. After determining that the deformation of the connection feature matches the external interference, the external interference can effectively affect the deformation trend of the connection feature. By amplifying the relative deformation amount over time, the design can be guided to discover the deformation position early and obviously, and make effective inspection and judgment analysis.

[0023] See also Figure 1 As shown, it is a connection block diagram of a building inspection system based on building design according to an embodiment of the present invention. This embodiment provides a building inspection system based on building design, including: A plurality of dimension measurement terminals, wherein a single dimension measurement terminal is used to obtain relative dimension data corresponding to connection features of a single modeling surface of a building within a monitoring period and position data of the dimension measurement terminal; A comprehensive measurement platform, which is connected to each of the dimension measurement terminals, is used to obtain measurement data and position data of each dimension measurement terminal, and to determine the time-series relative deformation amount of a single connection feature according to the relative dimension data of each single modeling surface. The comprehensive measurement platform is also used to determine the relative position change trend of the dimension measurement terminal according to the position data of each dimension measurement terminal; A matching verification module, which is connected to the dimension measurement terminal and the integrated measurement platform respectively, and is used to determine the external interference vector of the connection feature according to the relative position change trend of each dimension measurement terminal, and to correct the time series deformation amount of the single connection feature according to the external interference vector; A correction output module, which is connected to the integrated measurement platform and the matching inspection module respectively, and is used to determine the design dimension correction value of the modeling surface according to the time series deformation amount of the connection feature of the single modeling surface after correction; The position data is three-dimensional coordinate data determined according to a preset absolute reference base point, and the number of the dimension measurement terminals is at least three.

[0024] In implementation, a single dimension measurement terminal is used to measure the connection features of a corresponding modeling surface, and different dimension measurement terminals are used to measure the connection features of different modeling surfaces, and the measurement data obtained by the dimension measurement terminal is transmitted to the integrated measurement platform for data analysis through wired or wireless data transmission. It can be understood that the relative position change trend of the dimension measurement terminal is determined based on the position data of each dimension measurement terminal because at least three dimension measurement terminals can determine a plane through three points, and the force trend of the modeling surface of the building affected by the change of the building foundation in the environment can be obtained by measuring the relative position change of each leveling base. Preferably, a single dimension measurement terminal is set on the foundation surface other than the two connection objects of the corresponding monitored modeling surface to avoid interference with the two connection objects of the connection feature and affecting the measurement accuracy.

[0025] The present invention obtains the connection characteristics of the building modeling surface within the monitoring time period through each dimension measurement terminal, and combined with the relative position data changes of each dimension measurement terminal, it can effectively monitor and integrate the changing rules of the modeling surface connection characteristics under the time series state, and analyze them in an integrated manner. Combined with the changing trend of the modeling surface foundation, the time series deformation amount of a single connection feature is determined to guide the architectural design surveying and inspection and support subsequent design. On the one hand, the detection accuracy is improved, and on the other hand, by utilizing the time series detection data, the utilization rate of the building detection data can be improved, avoiding the waste of manpower and resource costs caused by the one-time use of a large amount of detection data.

[0026] See also Figure 2 As shown, it is a schematic diagram of the structure of a dimension measurement terminal according to an embodiment of the present invention. Specifically, the dimension measurement terminal includes: A leveling base is used to determine the horizontal position coordinates and height data of the current position; in implementation, the position data of a single measuring terminal is determined by a position sensing device installed on the leveling base at a set position, and each dimension measuring terminal used for detection uses a preset absolute reference base point (preferably set at a position outside the building) as the reference for the three-dimensional coordinate data. The data monitoring frequency and detection accuracy of each dimension measuring terminal are preferably set to synchronous detection to ensure the consistency and accuracy of the data.

[0027] A first feature measurement unit is arranged on the leveling base, and is used to respectively measure the three-dimensional position data of a preset first reference point on a first connection object of a single modeling surface and a preset first measurement point relative to the leveling base; a second feature measurement unit is arranged on the leveling base and is connected to the first feature measurement unit, and is used to respectively measure the three-dimensional position data of a preset second reference point on a second connection object of a single modeling surface and a preset second measurement point relative to the leveling base.

[0028] It can be understood that the first connection object and the second connection object are set as two structures connected to each other by connection characteristics of a single modeling surface. For example, the modeling surface of the building is an eave, and the protruding part of the eave is connected to the building wall part through a connection structure. At this time, the two connection objects are the protruding part of the eave and the building wall near the eave. As for the first connection object and the second connection object, they can be defined as needed and will not be described in detail here. After the connection object is determined, the corresponding reference point is preferably selected at a position close to the connection structure on the connection object, and the corresponding measurement point is preferably selected at a remote position on the connection object away from the connection structure, and the selection is within the range that can be measured by the size measurement terminal.

[0029] Both feature measurement units are set on the leveling base and fixedly connected to each other to ensure that the data obtained by the two feature measurement units have a consistent reference (the measurement reference of the two feature measurement units is the current position of their leveling bases). As for which measurement method to choose, there is no limitation here, as long as the three-dimensional position data of the corresponding point can be obtained by measuring the length or angle.

[0030] A feature output unit is respectively connected to the leveling base, the first feature measurement unit and the second feature measurement unit, and is used to determine the deformation path of the corresponding connection object based on the obtained three-dimensional position data of the single reference point and the corresponding measurement point relative to the leveling base, and to determine the deformation characteristics and relative position change trend of a single connection feature based on the relative deformation path between two relatively connected objects of a single modeling surface.

[0031] It can be understood that the feature output unit is a logic unit capable of performing analysis and calculation, which is built into the dimension measurement terminal and is used to perform analysis and calculation logic on the detected data. The feature output unit performs operations including: First operation analysis: Determine the deformation path of the corresponding connection object based on the obtained three-dimensional position data of the single reference point and the corresponding measurement point relative to the leveling base, and the deformation path can characterize the deformation change of the corresponding connection object itself.

[0032] Second operation analysis: Determine the deformation characteristics of a single connection feature according to the relative deformation path between two relatively connected objects of a single modeling surface, which can characterize the deformation change between two connected objects of a connection feature.

[0033] Specifically, the feature output unit determines a first deformation path of the first connection object based on the obtained three-dimensional position data of the first reference point and the preset first measuring point relative to the leveling base, and determines a second deformation path of the second connection object based on the obtained three-dimensional position data of the second reference point and the preset second measuring point relative to the leveling base, wherein the deformation path is formed according to the change of the position coordinates of the corresponding measuring point relative to the corresponding reference point.

[0034] Specifically, the relative deformation path is determined by the three-dimensional position coordinates of the midpoint between the first reference point and the second reference point within a monitoring period and the direction vector determined by the first measurement point and the second measurement point.

[0035] It can be understood that a straight line can be determined by the first reference point and the second reference point, and any reference point is set as the starting point, and the direction from the starting point to the other reference point is the direction vector currently detected. The time sequence formed by the change in the three-dimensional position coordinates of the midpoint of the line segment between the first reference point and the second reference point and the time sequence change in the direction vector constitutes a relative change path, and in extreme cases, the position change or direction change in the relative deformation path can be zero. The relative deformation path can characterize the deformation characteristics between two connected objects. Generally, the deformation characteristics are divided into three categories: The first category: linear deformation; its relative deformation path can be approximated as a straight line (the ratio of the difference between the position data detected at any two monitoring time points and the original detection data is within 3%), and the direction vector has almost no change in each stage of the time series (the change angle is within ±4°).

[0036] The second category: torsional deformation; its relative deformation path can be approximated as a straight line (the ratio of the difference between the position data detected at any two monitoring time points and the original detection data is within 3%), and the change angle of the direction vector is greater than ±4° in each stage of the time series.

[0037] The third category: flexible deformation; its relative deformation path is a curve (there are at least two sets of position data calculated from two arbitrary monitoring time points, and the ratio of the position difference to the original detection data is greater than 3%), and in each stage of the time series, the change angle of the direction vector is greater than ±4°.

[0038] Specifically, the feature output unit determines the relative position change trend according to the calculated time-series relative deformation amount, wherein the integrated measurement platform determines the time-series relative deformation amount of the corresponding connection feature according to the displacement amount of the midpoint and the direction vector.

[0039] It can be understood that the time series relative deformation variable is a vector. Calculating the time series relative deformation variable includes calculating the deformation direction per unit time and the change distance per unit time. The calculation method includes: In one embodiment, a first approximate straight line path is determined according to a first deformation path, a second approximate straight line path is determined according to a second deformation path, and the deformation direction per unit time and the change distance per unit time are determined according to the first approximate straight line path and the second approximate straight line path. It is understandable that when determining the corresponding approximate straight line path according to the corresponding deformation path, it is preferably implemented in two connected objects whose deformation characteristics are linear deformations, and the corresponding approximate straight line path can be determined according to any method of determining the closest straight line according to discrete points in the prior art, which will not be repeated here. After determining the approximate straight line path, the corresponding detection data is projected onto the corresponding approximate straight line path to obtain the corresponding approximation data, and the deformation direction per unit time and the change distance per unit time are determined according to the approximation data corresponding to the two approximate straight line paths.

[0040] Or in another embodiment, the deformation direction per unit time and the distance changed per unit time are calculated based on the change in the three-dimensional position coordinates of the midpoint of the line segment between the first reference point and the second reference point and the displacement of the determined midpoint and the direction vector of the midpoint in the time series. At this time, based on the time series change trend graph of the displacement, a corresponding polynomial can be taken to represent the change in the displacement, and the calculation formula can be used to approximately calculate the distance changed per unit time; based on the time series change trend graph of the direction vector of the midpoint in the time series, a corresponding polynomial can be taken to represent the change in the direction vector, and the calculation formula can be used to approximately calculate the deformation direction per unit time.

[0041] See also Figure 4 As shown, it is a schematic diagram of the three-dimensional coordinates of a single deformation path of an embodiment of the present invention. In one embodiment, when determining the deformation path, a single reference point is used as the origin, the positioning reference plane of the leveling base is used as the horizontal plane, and the plane perpendicular to the leveling base determined by the reference point and the corresponding measuring point is used as the vertical plane to determine the horizontal axis and the vertical axis of the three-dimensional coordinates. The change in the position coordinates of the measuring point relative to the corresponding reference point forms the deformation path of the corresponding connected object. The dotted line in the figure is the approximate straight line 1 of the calculated deformation path.

[0042] Specifically, the relative position change trend of the dimension measurement terminal includes the plane position change direction and change angle; The integrated measurement platform determines the relative position change trend of the dimension measurement terminal according to the average plane position change direction and average change angle of the reference plane determined based on the position data of any three dimension measurement terminals among the dimension measurement terminals.

[0043] In implementation, the reference plane determined according to the position data of any three dimension measurement terminals among the dimension measurement terminals can be used as the closest plane in the current tense, the plane angle change per unit time calculated by the plane position change direction of the closest plane corresponding to each tense is taken as the average plane position change direction, the plane angle change direction per unit time calculated by the plane position change direction of the closest plane corresponding to each tense is taken as the average change angle, and the relative position change trend of the dimension measurement terminal is calculated, and the change trend includes the plane angle change per unit time and the plane angle change direction per unit time calculated as above.

[0044] During implementation, the plane position change direction and change angle of the reference plane determined by the integrated measurement platform according to the position data of any three dimension measurement terminals in each dimension measurement terminal can be used to form a plane position change direction data set and a change angle data set in a single time state, and the data in the data set can be averaged to obtain the average plane position change direction and average change angle in the corresponding time state, and then the average plane position change direction and average change angle can be obtained in each time state in turn to form the relative position change trend of the dimension measurement terminal.

[0045] Specifically, the matching verification module determines the external interference vector of the connection feature according to the plane position change direction and change angle corresponding to the relative position change trend.

[0046] In implementation, the matching verification module is usually preset with a change angle threshold, and the interference of the relative position change trend less than the change angle threshold is considered to be a stable disturbance and can be ignored. Preferably, the change angle threshold is set to 2°, and the reference plane deviation less than or equal to two degrees is not calculated for the external interference vector.

[0047] For a reference plane deviation greater than 2°, the external interference vector is calculated. At this time, the direction of the external interference vector is the direction of the plane position change, and the length of the external interference vector is determined according to the change angle. It should be pointed out in particular that the length of the external interference vector only represents the intensity of the external interference. The larger the change angle, the larger the length of the external interference vector.

[0048] Specifically, the matching verification module determines whether to correct the temporal relative deformation amount of the corresponding connection feature according to the matching relationship between the single deformation path of the connection feature of the single modeling surface and the external interference vector, wherein: If any deformation path of the connection features of a single modeling surface matches the external interference vector, it is determined that the temporal relative deformation amount of the corresponding connection feature needs to be corrected.

[0049] In implementation, the matching is usually set to mean that the angle between a single deformation path of a single connected object in the corresponding time state and the direction of the external interference vector is less than 30°.

[0050] Furthermore, in implementation, it is possible to perform data trend consistency analysis on multiple connection features of the same type. If the matching rate between the deformation path of the same type of connection features and the external interference vector is greater than 80%, the data consistency is considered good, and the relative deformation amount of the connection feature time series is determined to be corrected.

[0051] It can be understood that the correction here is to increase the time-series relative deformation. This is because, after determining that the deformation of the connection feature matches the external interference, the external interference can have an effective impact on the deformation trend of the connection feature. By amplifying the time-series relative deformation, the design can be guided to find the deformation position early and obviously, and make effective inspection and judgment analysis. Among them, the increment of the time-series relative deformation is determined by multiplying the connection strength coefficient of the connection feature by the original data in proportion. According to the different connection materials, generally, the connection strength coefficient of cement / colloid connection is set to 1.05, the connection strength coefficient of steel structure welding is 1.01, and the connection strength coefficient of steel structure hinge is 1.10. Other materials can be calculated based on the control variable strength test of a large amount of data collection and environmental interference and based on the three coefficients given above, which will not be repeated here.

[0052] Specifically, the correction output module determines the design dimension correction value of the modeling surface according to the time-series relative deformation amount of the corrected connection feature, wherein: The correction output module determines the design dimension correction value of the modeling surface according to the time-series relative deformation amount of the connection feature before and after correction to form a dimension correction range and a correction coefficient, and determines the correction influence coefficient according to the building position of the modeling surface and the correction coefficient to determine the design dimension correction value of the modeling surface.

[0053] It can be understood that the correction coefficient is the connection strength coefficient mentioned above. Whether to increase the correction coefficient is determined according to the historical environmental disturbance of the building location, and the correction influence coefficient is formed after judgment. For example, in areas with frequent geological activities, the historical environmental disturbance is large. At this time, the correction coefficient needs to be increased, and the correction influence coefficient is obtained by multiplying the correction coefficient by the building location coefficient (the value is between 1 and 1.05, and the greater the historical environmental disturbance, the greater the value)

[0054] After determining the temporal relative deformation of the connection feature, the theoretical connection relationship at the design time point is determined according to the modeling accuracy at the desired inspection time point, and the temporal relative deformation in the determined time period between the construction time point and the inspection time point is subtracted to obtain the design dimension correction value.

[0055] See also Figure 3 As shown, in a specific embodiment, a building inspection method applied to the above-mentioned building inspection system is provided, which includes: Step S1, respectively setting a dimension measurement terminal on the modeling surface corresponding to each connection feature, obtaining the dimension data corresponding to the connection feature of a single modeling surface and the position data of each dimension measurement terminal relative to an absolute reference base point; Step S2, continuously obtaining, within a monitoring period, dimension data corresponding to the connection features of a single modeling surface collected by each dimension measurement terminal and position data of each dimension measurement terminal relative to an absolute reference base point; Step S3, calculating the time-series relative deformation amount of a single connection feature according to the relative size data of each single modeling surface; Step S4, determining the relative position change trend of the size measurement terminal according to the position data of each size measurement terminal; Step S5, determining an external interference vector of a connection feature according to a relative position change trend of each of the size measurement terminals; Step S6, determining whether to correct the temporal deformation amount of the single connection feature according to the external interference vector; Step S7, determining the design dimension correction value of the modeling surface according to the corrected temporal deformation amount of the connection feature of the single modeling surface.
