Description

Technical Field

[0001] The present application relates to the field of deformation monitoring technology, and in particular to a monitoring method, system and storage medium for building deformation. Background Art

[0002] In construction projects, modular building boxes are easily deformed due to bumps during production, lifting and transportation. In traditional methods, when the deformation process and location are uncertain, operators generally use elastic ink lines to find the location of the box deformation. However, this method can only reflect whether the building box is deformed and the location of the deformation, but cannot reflect the deformation process of the building box. Deformation is a gradual process, and operators cannot obtain the deformation nodes from the location of the deformation, which is not conducive to the subsequent optimization of the process of the modular building box by the operator.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0049] Reference Figure 2 In a first aspect, an embodiment of the present application provides a method for monitoring building deformation, including but not limited to steps S110, S120, S130, S140, and S150.

[0050] Step S110, the monitoring device reciprocates in the frame structure corresponding to the building, and when the monitoring device passes through the monitoring node, the monitoring device obtains measurement data corresponding to the monitoring node, wherein the measurement data includes first measurement data obtained in real time and second measurement data obtained at intervals, and the first measurement data and the second measurement data are respectively set in one-to-one correspondence with the monitoring nodes;

[0051] Step S120, obtaining the current first measurement data of the node and the previous first measurement data of the node corresponding to each monitoring node, comparing the current first measurement data of the node with the previous first measurement data of the node to obtain first comparison data, wherein the first measurement data includes the current first measurement data of the node and the previous first measurement data of the node;

[0052] Step S130, when the first comparison data satisfies the first deformation condition, obtaining the corresponding co-located current first measurement data between different monitoring nodes, comparing the node current first measurement data with the co-located current first measurement data to obtain second comparison data, wherein the first measurement data also includes the co-located current first measurement data;

[0053] Step S140, when the second comparison data satisfies the second deformation condition, the initial three-dimensional model and the target three-dimensional model are compared to obtain deviation data between the initial three-dimensional model and the target three-dimensional model, wherein the initial three-dimensional model is constructed by a frame structure corresponding to the building, and the target three-dimensional model is constructed by the second measurement data;

[0054] Step S150, obtaining a deformation result corresponding to the building according to the deviation data;

[0055] It can be understood that the monitoring device in the present application is an active strain sensor. The strain sensor converts the change of the measured point into the change of the resistance value of the sensor element, and then converts it into an electrical signal through a circuit, so that the control system can intuitively monitor whether the building is deformed. On the other hand, if the frame structure of the building is a hollow structure, the monitoring device of the present application can be set inside the frame structure of the building, or it can be set on the surface of the frame structure of the building. When the monitoring device is set inside the frame structure of the building, the movement of the building will not be affected by external interference. If the monitoring device is set on the surface of the frame structure of the building, the reciprocating movement monitoring process of the building will be more intuitive. The present application does not specifically limit the setting position of the monitoring device, and it is sufficient to enable the monitoring device to reciprocate and transmit measurement data (such as first measurement data acquired in real time and second measurement data acquired at intervals) in the frame structure of the building.

[0056] It should be noted that the statement in the present application that “the monitoring device in the present application is an active strain sensor” does not constitute a limitation of the present application. In actual application, the monitoring device can be a strain sensor, or a piezoresistive sensor, a potentiometer sensor, etc., which can enable the control system to monitor the state changes of the building in real time.

[0057] According to one embodiment of the present application, in the monitoring method of building deformation of the present application, by setting a plurality of monitoring devices at each monitoring node of the building, the first measurement and comparison of the monitoring nodes is first performed in real time by the reciprocating monitoring device. When the result of the first measurement and comparison, i.e., the first comparison data, meets the first deformation condition, a second measurement and comparison is performed in combination with the same-position current first measurement data corresponding to different monitoring nodes. When the result of the second measurement and comparison, i.e., the second comparison data, meets the second deformation condition, a third measurement and comparison is performed on each monitoring node at a set monitoring time interval to obtain the second measurement data, and the second measurement data is transmitted to the control system. The control system processes the second measurement data to establish a target three-dimensional model, and obtains the current state of the building, i.e., the deformation result, by analyzing the deviation data between the initial three-dimensional model and the target three-dimensional model. The present application facilitates operators to quickly discover deformation processes and deformation nodes through three measurement and comparison, which is beneficial to the subsequent optimization of the building process.

[0058] According to an embodiment of the present application, the purpose of performing the first measurement comparison and the second measurement comparison is to distinguish the measurement singularity and the deformation point. It should be noted that the first measurement data includes the current first measurement data of the node and the previous first measurement data of the node, wherein the previous first measurement data of the node and the current first measurement data of the node refer to: the measurement data recorded when the monitoring device passes the monitoring node for the first time when the monitoring device continuously reciprocates on the frame structure of the building, and the measurement data recorded when the monitoring device passes the same monitoring node for the second time; it can be understood that in some embodiments, since the monitoring device reciprocates in the frame structure corresponding to the building, the measurement data recorded when the monitoring device currently passes the same monitoring node can be used as the current first measurement data of the node, and the measurement data recorded when the monitoring device last passed the same monitoring node can be used as the previous first measurement data of the node. In the first measurement comparison, the monitoring device reciprocates on the frame structure of the building, and continuously obtains the previous first measurement data of the node and the current first measurement data of the node, and compares the previous first measurement data of the node with the current first measurement data of the node, calculates the difference between the previous first measurement data of the node and the current first measurement data of the node, and obtains the first comparison data.

[0059] It can be understood that as the monitoring device continues to reciprocate and sample on the frame structure of the building, the previous first measurement data of the node and the current first measurement data of the node will continue to be updated and changed, the first measurement comparison will be repeatedly executed, and the first comparison data will also be repeatedly updated. It can be understood that the monitoring device performs at least three reciprocating motions on the frame structure of the building to ensure the accuracy of the first measurement comparison and the second measurement comparison to obtain the actual situation of the building.

[0060] It should be noted that the building deformation monitoring method of the present application performs three different comparisons on the collected first measurement data and the second measurement data to obtain the real-time status of the building. The present application monitors the deformation and current status of the building based on the first measurement data and the second measurement data. It can be understood that the first measurement data is collected in real time, the first measurement comparison and the second measurement comparison are also performed in real time, and the second measurement data is collected at interval monitoring time, and the third measurement comparison is also collected at interval monitoring time.

[0061] Reference Figure 3 , an embodiment of the present application provides a method for obtaining first comparison data, that is, comparing the current first measurement data of a node with the previous first measurement data of the node to obtain the first comparison data, including but not limited to step S210.

[0062] Step S210, calculating the difference between the previous first measurement data of the node and the current first measurement data of the node to obtain first comparison data;

[0063] It can be understood that the first measurement data includes the current first measurement data of the node and the previous first measurement data of the node. The data formats of the previous first measurement data of the node and the current first measurement data of the node are processed, and the difference between the previous first measurement data of the node and the current first measurement data of the node is calculated. The difference calculated at this time is the first comparison data, and the control system stores and records the first comparison data.

[0064] According to one embodiment of the present application, on the other hand, the monitoring device continuously performs reciprocating motion on the frame structure of the building, performs several measurements on several monitoring nodes, and in the process of the first measurement and comparison, determines whether the current state of the monitoring node is a convex state or a flat state. Specifically, if a monitoring node is determined to be in a convex state during the first measurement, and this monitoring node is still in a convex state in subsequent measurements, then the monitoring node is determined to be a deformation point. If this monitoring node returns to a flat state in subsequent measurements, then the monitoring node is determined to be a measurement singularity, and the second measurement and comparison is entered. In combination with the second measurement and comparison, the monitoring node is analyzed again.

[0065] Reference Figure 4 , an embodiment of the present application provides a method for determining first comparison data, that is, when the first comparison data satisfies a first deformation condition, including but not limited to step S310.

[0066] Step S310, when the first comparison data is higher than a preset first threshold, the first deformation condition is met;

[0067] It should be noted that if the first comparison data is less than the preset first threshold, the monitoring node has not been deformed. If the first comparison data is greater than the preset first threshold, the monitoring node may be a measurement singularity or a deformation point. This situation meets the first deformation condition and enters the second measurement comparison, where the first threshold is the critical value of the deformation. When the first comparison data meets the first deformation condition, it indicates that it is still impossible to determine whether the current monitoring node is a deformation point. Therefore, the control system needs to perform a second measurement comparison on the current state of the building to determine whether the current monitoring node is a deformation point.

[0068] Reference Figure 5 An embodiment of the present application provides a method for obtaining second comparison data, that is, obtaining the corresponding current first measurement data of the same location between different monitoring nodes, comparing the current first measurement data of the node with the current first measurement data of the same location, and obtaining second comparison data, including but not limited to step S410 and step S420.

[0069] Step S410, obtaining a plurality of co-located current first measurement data that are in the same monitoring period as the current first measurement data of one of the nodes and are located at different monitoring nodes, wherein, when the monitoring node corresponding to the current first measurement data of the node is located on the first beam, the monitoring node corresponding to the co-located current first measurement data is located on a beam other than the first beam; and / or, when the monitoring node corresponding to the current first measurement data of the node is located on the first column, the monitoring node corresponding to the co-located current first measurement data is located on a column other than the first column;

[0070] refer to Figure 1 , Figure 1 A schematic diagram of a frame structure of a building provided for some embodiments of the present application; according to one embodiment of the present application, due to uneven stress on the building, in order to meet the stress requirements of various parts of the building, the cross-section of the frame structure of the building is not fixed, and different frame structures of the building undergo different degrees of deformation due to stress. When measuring the building, it is necessary to consider whether the measured monitoring node is a measurement singularity or a deformation point, wherein the measurement singularity is the deformation of the building frame structure due to uneven stress, and the deformation point is the deformation deviation of the building caused by the manufacturing, decoration or installation process. The building deformation monitoring method of the present application is applied to a modular building box, the modular building box includes a first structural surface, a second structural surface and a plurality of columns, the first structural surface and the second structural surface both include a plurality of beams connected end to end in sequence, the first structural surface is arranged in parallel with the second structural surface and the first structural surface is connected to the second structural surface through a column, and the column is vertically connected to the first structural surface and the second structural surface respectively.

[0071] It is understandable that at least one monitoring device is provided on each beam and each column of the frame structure of the building, and the monitoring device reciprocates in the frame structure corresponding to the building to monitor the nodes that are prone to deformation, such as the corners of the building, the middle of the column, the middle of the beam, the cantilever end, and the position of the variable-section beam column, that is, to monitor the status of the monitoring node in real time, so as to facilitate the timely discovery of the deformation of the building. Each time the monitoring device passes through the monitoring node, it records the first measurement data of the monitoring node. During the reciprocating movement, the monitoring device records the first measurement data measured by each monitoring node, and sets the monitoring time at the same time. The second measurement data of the monitoring node is recorded every unit of monitoring time, and the second measurement data is sent to the control system, wherein the first measurement data and the second measurement data are respectively set in one-to-one correspondence with the monitoring node.

[0072] Step S420, calculating the difference between the current first measurement data of the node and the current first measurement data of the same node to obtain second comparison data;

[0073] According to one embodiment of the present application, the second measurement comparison is to exclude the measurement singularity that was not determined by the first measurement comparison, and the first measurement data of multiple co-located monitoring nodes are compared on the basis of the first deformation condition. When the first comparison data satisfies the first deformation condition, the co-located current first measurement data that is co-located with the current first measurement data of the node is obtained, wherein the first measurement data includes the co-located current first measurement data. It can be understood that the co-located current first measurement data refers to the first measurement data collected by the monitoring device that is in the same monitoring period as the current first measurement data of the node and is located at a different monitoring node. Specifically, the framework structure of the present application includes a plurality of horizontally arranged beams and a plurality of vertically arranged columns. The beams and columns are subjected to different forces, and the measurement singularities that appear are also different. The measurement singularities between beams are the same, and the measurement singularities between columns are the same. To eliminate measurement singularities, when the monitoring node corresponding to the current first measurement data of a node is located on the first beam, the monitoring node corresponding to the current first measurement data at the same location is located on beams other than the first beam. For example, if there are eight beams in total, the monitoring node corresponding to the current first measurement data at the same location is located on seven beams other than the first beam. When the monitoring node corresponding to the current first measurement data of a node is located on the first column, if there are four columns in total, the monitoring node corresponding to the current first measurement data at the same location is located on three columns other than the first column.

[0074] According to one embodiment of the present application, the first measurement data also includes the current first measurement data of the same location. The data formats of the current first measurement data of the node and the current first measurement data of the same location are processed, and the difference between the current first measurement data of the node and the current first measurement data of the same location is calculated. The difference calculated at this time is the second comparison data, and the control system stores and records the second comparison data.

[0075] It should be noted that as the monitoring device continues to reciprocate and sample on the frame structure of the building, the current first measurement data at the same location and the current first measurement data at the node will continue to update and change, the second measurement comparison will be repeatedly executed, and the second comparison data will also be repeatedly updated.

[0076] refer to Figure 6 , an embodiment of the present application provides a method for constructing a target three-dimensional model, wherein the target three-dimensional model is constructed by second measurement data, including but not limited to steps S510 and S520.

[0077] Step S510, performing format conversion processing on the second measurement data to obtain a three-dimensional point cloud corresponding to the second measurement data;

[0078] Step S520, constructing a target three-dimensional model according to the three-dimensional point cloud corresponding to the second measurement data;

[0079] It is understandable that the third measurement and comparison process includes format conversion processing of the second measurement data, and constructing a target three-dimensional model based on the three-dimensional point cloud corresponding to the second measurement data. The third measurement and comparison is to monitor whether the overall frame structure of the building is deformed or skewed. If the frame structure of the building is skewed or deviated as a whole due to transportation or construction, the first measurement and comparison and the second measurement and comparison may not be able to detect it. In order to ensure the effectiveness of the building deformation monitoring method of the present application, a third measurement and comparison is required. The third measurement and comparison processes the second measurement data obtained by measuring the interval monitoring time, establishes a target three-dimensional model, and compares the real-time established target three-dimensional model with the preset initial three-dimensional model, so as to more intuitively monitor the overall frame structure of the building, thereby facilitating the deformation result of the building.

[0080] According to an embodiment of the present application, before the monitoring device performs the first measurement and comparison on the building, the control system establishes an initial three-dimensional model according to the initial frame structure of the building, and stores and records the corresponding data of the initial three-dimensional model. When the second comparison data meets the second deformation condition, the second measurement data collected during the interval monitoring time is subjected to data fitting processing to achieve the purpose of format conversion, so that the second measurement data is converted into a corresponding concrete three-dimensional point cloud. It should be noted that in the process of converting the second measurement data into a three-dimensional point cloud, in order to reduce the influence of the position deviation of the building on the judgment of the control system and make the constructed target three-dimensional model more accurate, the construction process of the three-dimensional point cloud takes into account the thickness factor and position deviation factor of the frame structure of the building, for example, subtracting the thickness and position deviation of the steel plate in the frame structure of the building. Based on the obtained three-dimensional point cloud, the control system unifies the origin of all three-dimensional point clouds, sets the starting point, and connects the three-dimensional point clouds to construct the target three-dimensional model.

[0081] refer to Figure 7 The embodiment of the present application provides a method for obtaining deviation data, that is, when the second comparison data satisfies the second deformation condition, the initial three-dimensional model and the target three-dimensional model are compared to obtain the deviation data between the initial three-dimensional model and the target three-dimensional model, including but not limited to steps S610 and S620.

[0082] Step S610, when the second comparison data is greater than a preset second threshold, the second deformation condition is met;

[0083] Step S620, obtaining deviation data between the initial three-dimensional model and the target three-dimensional model by performing model collision processing on the initial three-dimensional model and the target three-dimensional model;

[0084] According to an embodiment of the present application, because there are multiple first measurement data at the same location, multiple second comparison data are obtained. If multiple second comparison data are all less than the preset second threshold, the monitoring node is a measurement singularity. If the second comparison data is greater than the preset second threshold, it is necessary to combine the second comparison data of other monitoring nodes at the same location for judgment. If the second comparison data of other monitoring nodes at the same location is also greater than the preset second threshold, the second deformation condition is met and the node is a deformation point. If the second comparison data of other monitoring nodes at the same location are all less than the preset second threshold, the node is a measurement singularity. The monitoring node at the same location whose second comparison data is greater than the preset second threshold may be a deformation point, and a second measurement comparison judgment is performed on the monitoring node at the same location. The second threshold is the critical value of deformation.

[0085] It is understandable that after the second measurement and comparison, the second comparison data obtained satisfies the second deformation condition, the initial three-dimensional model and the target three-dimensional model are compared, and the initial three-dimensional model and the target three-dimensional model are subjected to model collision processing. It should be noted that collision checking is a major task of eliminating changes and rework using BIM technology. In engineering, the intersection of entities is defined as a collision, and the distance between entities is less than the set tolerance, which affects the construction or fails to meet specific requirements. It is also defined as a collision. The building deformation monitoring method of the present application obtains the deviation data between the initial three-dimensional model and the target three-dimensional model through collision processing, so that the control system detects the deformation deviation in real time and immediately feeds back the deformation deviation information.

[0086] According to one embodiment of the present application, a monitoring device installed on a building is also provided with an early warning device. When a deformation deviation occurs at a monitoring node, the control system outputs an early warning signal in response to the deformation information of the corresponding monitoring node, and feeds back to the early warning system on the monitoring device where the deformation occurs. When the early warning system receives the early warning signal, the early warning system activates the alarm function, and the early warning device on the monitoring node where the deformation occurs sounds an alarm.

[0087] It should be noted that the statement “the method for monitoring building deformation of the present application is applied to modular building boxes” in the method for monitoring building deformation of the present application does not constitute a limitation on the present application. The present application can be applied not only to modular building boxes, but also to monitor other large buildings that may deform, such as bridges, walls, etc. The present application does not make specific limitations on it, and it is sufficient to support the reciprocating motion of the monitoring device of the present application and measure the interval monitoring time.

[0088] Second, refer to Figure 8 , the embodiment of the present application provides a monitoring system for building deformation, including:

[0089] at least one memory 200;

[0090] at least one processor 100;

[0093] A method for monitoring building deformation as in any embodiment of the first aspect of the present application.

[0094] The processor 100 and the memory 200 may be connected via a bus or other means.
