[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention is described clearly and completely below. Obviously, the described embodiments are 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 persons in the art without creative work are within the scope of protection of the present invention.

[0042] As the demand for liquefied natural gas increases year by year, higher requirements are placed on the storage capacity of liquefied natural gas. Generally, liquefied natural gas is stored in storage tanks.

[0043] The tank top beam frame structure is a spherical crown-shaped large-span space lattice shell structure with a diameter of nearly 100m. It is welded on-site by more than 1,000 steel sections, and errors accumulate during the construction process. In addition, the top beam frame may undergo large deformation and settlement during the splicing and hoisting process, and will continue to deform significantly during the huge dome concrete ring or layer pouring construction process. The above factors cause the top beam frame to continuously deform significantly throughout its life cycle, and there is always a significant difference from the design state. Therefore, the stability of the tank top beam frame structure is crucial.

[0044] However, it is currently impossible to detect whether the tank top beam frame structure is damaged, and it is difficult to determine the health status of the tank, resulting in risks in the storage of liquefied natural gas. In response to the above technical problems, the present invention provides a damage identification method, device, equipment, medium and product for the tank top beam frame structure, which can effectively determine the damage of the tank top beam frame structure. The technical solution of the present invention is described in detail below with reference to specific examples.

[0045] Reference Figure 1 As shown, the damage identification method of a tank top beam frame structure involved in the present invention comprises:

[0046] S110, constructing a simulation model corresponding to the tank top beam frame structure of the storage tank to be tested according to the point cloud data of the storage tank to be tested;

[0047] S120, according to the current construction stage of the tank top beam frame structure, determining a corresponding structural deformation threshold value in a preset correspondence relationship between the construction stage and the structural deformation threshold value;

[0048] S130. When the structural deformation value of the simulation model exceeds the structural deformation threshold, determine a damage position of the tank top beam frame structure according to the structural deformation value.

[0049] In step S110, the storage tank to be tested is illustratively a storage tank that needs to be identified for damage. The point cloud data is represented by three-dimensional coordinates. For example, by collecting point cloud data through a three-dimensional laser scanner, it is possible to perform a full-scale, high-precision scan to obtain the three-dimensional coordinates, color, texture and other information of its surface. The three-dimensional laser scanner includes a ground laser scanner, a backpack laser scanner or a handheld laser scanner.

[0050] Specifically, the point cloud data of the storage tank to be tested can be obtained by a three-dimensional laser scanner, the point cloud data corresponding to the top beam frame of the storage tank can be screened from the point cloud data of the storage tank to be tested, and the point cloud data corresponding to the top beam frame of the storage tank can be simulated using a simulation model to obtain a corresponding simulation model. For example, simulation software can be used to simulate the point cloud data corresponding to the top beam frame of the storage tank to generate a simulation model.

[0051] Specifically, the tank top beam frame may be scanned by a three-dimensional laser scanner to obtain point cloud data corresponding to the tank top beam frame, and the point cloud data corresponding to the tank top beam frame may be simulated by using a simulation model to obtain a corresponding simulation model.

[0052] In step S120, illustratively, the construction stages include an assembly construction stage, a concrete ring pouring construction stage, and a pressure-maintaining construction stage. The correspondence between the preset construction stages and the structural deformation thresholds is a pre-stored deformation threshold of the top beam frame structure at different construction stages. Specifically, the correspondence between the preset construction stages and the structural deformation thresholds is obtained by pre-statistical analysis of a large amount of historical experimental data. For example, the assembly construction stage corresponds to the structural deformation threshold A, the concrete ring pouring construction stage corresponds to the structural deformation threshold, and the pressure-maintaining construction stage corresponds to the structural deformation threshold C.

[0053] Furthermore, if Figure 2As shown, the method for determining the correspondence between the preset construction stage and the structural deformation threshold includes: S210, determining multiple buckling instability conditions according to the construction data of the tank top beam frame structure samples at different construction stages; S220, performing numerical simulation on the tank top beam frame structure samples according to the multiple buckling instability conditions to generate a set of structural deformation values; S230, determining the structural deformation threshold corresponding to each construction stage for the set of structural deformation values ​​of each construction stage.

[0054] For example, the tank top beam frame structure sample can be a simulation model of a specified tank top beam frame structure, or a simulation model of any tank top beam frame structure, which is not limited here. The construction data refers to the data used in actual construction. The construction data includes size, material properties, construction method, etc.

[0055] Specifically, since the tank top beam frame structure samples at different construction stages correspond to different construction data, the construction data of each construction stage includes multiple parameters, and the parameters in the construction data are modified one by one to form multiple buckling instability conditions, that is, only one parameter is modified each time, and the modified parameter is output together with the unmodified parameter as a buckling instability condition.

[0056] In this embodiment, a special structural buckling analysis module in the finite element software is used to pre-use the buckling instability conditions to simulate the structural buckling, so as to achieve the simulation of the buckling instability values ​​(i.e., structural deformation values) of the tank top beam frame structure sample under a large number of different positions and degrees of defect conditions in the assembly construction stage, the concrete ring pouring construction stage, and the pressure maintenance construction stage, and obtain the deformation of the critical state top beam frame structure. The various structural deformation values ​​are combined into a critical state deformation value training set, that is, they are respectively determined as the structural deformation thresholds corresponding to each construction stage, so as to form a corresponding relationship between the construction stage and the structural deformation threshold. Furthermore, in the corresponding relationship between the construction stage and the structural deformation threshold, the construction stage records its corresponding construction data.

[0057] Furthermore, after determining the current construction stage of the tank top beam frame structure and the construction data of the current construction stage, the correspondence between the construction stage and the structural deformation threshold is obtained, and the structural deformation threshold corresponding to the current construction stage is found in the above correspondence according to the current construction stage and the construction data of the current construction stage.

[0058] In step S130, illustratively, a target simulation model is obtained by pre-simulating a top beam frame structure without damage, and a numerical comparison is performed between the simulation model obtained in step S110 and the target simulation model to determine the structural deformation value of the simulation model.

[0059] Preferably, step S130 includes: inputting the structural deformation value into a damage identification model, and outputting the damage position of the tank top beam frame structure; wherein the damage identification model is obtained by performing damage identification training based on the structural deformation value samples of the tank top beam frame structure under different buckling instability conditions and the corresponding damage position samples.

[0060] Specifically, the structural buckling simulation of the tank top beam frame structure is carried out under different buckling instability conditions to output the corresponding structural deformation value samples, and the damage position samples of the tank top beam frame structure corresponding to each structural deformation value sample are recorded. The structural deformation value samples and the damage position samples are used as a set of training data, so that multiple sets of training data are obtained to form a training data set.

[0061] The neural network model is trained for damage identification based on the training data set, and the prediction results are compared with the damage location samples to determine the loss results. The neural network model parameters are optimized based on the loss results to obtain the damage identification model. In this way, damage identification of the structural deformation value can be performed based on the damage identification model, and the damage location of the tank top beam frame structure under various working conditions can be effectively determined.

[0062] In the technical solution of the present application, a simulation model corresponding to the tank top beam frame structure of the tank to be tested is constructed based on the point cloud data of the tank to be tested; according to the current construction stage of the tank top beam frame structure, the corresponding structural deformation threshold is determined in the correspondence between the preset construction stage and the structural deformation threshold; when the structural deformation value of the simulation model exceeds the structural deformation threshold, the damage position of the tank top beam frame structure is determined according to the structural deformation value. In this way, the damage position of the tank top beam frame structure can be accurately identified by combining the current construction stage of the tank top beam frame structure with the structural deformation value of the simulation model.

[0063] In one embodiment, the structural deformation value set for each construction stage determines the structural deformation threshold corresponding to each construction stage, including:

[0064] Determine the corresponding safety margin interval according to each construction stage;

[0065] The structural deformation threshold corresponding to each construction stage is predicted by using the safety margin interval and the set of structural deformation values ​​at each construction stage.

[0066] Specifically, the safety margin interval represents the interval close to damage in the construction stage. Different construction stages correspond to different safety margin intervals, or may correspond to the same safety margin interval. It is understandable that the safety margin interval is set based on actual experience and is not limited here.

[0067] Optionally, the structural deformation threshold corresponding to each construction stage may be added to the safety margin interval corresponding to each construction stage to obtain an updated structural deformation threshold interval corresponding to each construction stage.

[0068] Optionally, the prompt text uses the safety margin interval [a, b] to update the structural deformation threshold in the current construction stage, and the prompt text and the structural deformation threshold are used as inputs of the large language model. The large language model outputs the updated structural deformation threshold based on its own analysis capabilities, the construction stage, the safety margin interval and the structural deformation threshold. In this way, the safety margin is taken into account to avoid the structural deformation threshold being the structural deformation threshold of the damaged top beam frame structure, thereby ensuring the safety of the structural deformation threshold.

[0069] In one embodiment, if Figure 3 As shown, according to the point cloud data of the storage tank to be tested, a simulation model corresponding to the tank top beam frame structure of the storage tank to be tested is constructed, and step S110 includes:

[0070] S1110, filtering out the point cloud data of the top beam frame structure of the storage tank from the point cloud data of the storage tank to be tested;

[0071] S1120, simulating the point cloud data of the tank top beam frame structure according to a preset simulation model to obtain a simulation model.

[0072] In this embodiment, a 3D laser scanner is used to collect the original point cloud data of the top beam frame structure, that is, the top beam frame is scanned in an all-round and high-precision manner to obtain the 3D coordinates, reflectivity, color and other data information of its surface. In this way, the information of the surface material of the structure, such as the paint coverage, etc., can be reflected, which is helpful for subsequent damage identification.

[0073] After the data collection is completed, the original point cloud data is preprocessed, including operations such as removing noise, filling holes, and smoothing the surface to improve the quality and accuracy of the data. At the same time, the original point cloud data also needs to be processed by coordinate conversion and format conversion. Finally, the original point cloud data scanned from different perspectives and different time periods are aligned and fused to obtain a complete point cloud model. Then, the point cloud data of some structures other than the top beam frame in the point cloud model are removed, and then the noise points near the point cloud model corresponding to the top beam frame structure are removed, and finally the target point cloud model containing only the top beam frame structure is obtained. Finally, the digital twin model is used to identify the contour of the target point cloud model. Since the top beam frame structure is composed of I-beams, its cross-section is a huge I-shaped, and the basis for comparison, that is, the contour line or center line, needs to be clearly defined. Therefore, the contour line and center line of the medium-shaped steel of the top beam frame structure are obtained. And the color, reflectivity and other information are reflected in the digital twin model to generate a digital twin model of the top beam frame structure. It can be seen that since the preset simulation model is a digital twin model, the digital twin model collects information such as contour lines, center lines, colors, and reflectivity, which can more realistically present the top beam frame structure, thereby more accurately calculating the deformation value of the top beam frame structure, and then more accurately identifying the damage location of the top beam frame structure.

[0074] In one embodiment, when the structural deformation value of the simulation model exceeds the structural deformation threshold, after determining the damage position of the tank top beam frame structure according to the structural deformation value, the method further includes:

[0075] It is determined that the tank top beam frame structure is in an unstable state, and an instability alarm is sent.

[0076] In this embodiment, if the structural deformation value of the simulation model exceeds the structural deformation threshold, it means that the tank top beam frame structure corresponding to the simulation model is at risk of damage and is in an unstable state, and an instability alarm is sent to the staff. The instability alarm can be in the form of a message or email, or it can be an alarm using lights (such as LED lights) and / or sounds (such as buzzers) on the staff's central control platform.

[0077] The present invention also provides a damage identification device for a tank top beam frame structure, referring to Figure 4 As shown, including:

[0080] The identification module 430 is used to determine the damage position of the tank top beam frame structure according to the structural deformation value when the structural deformation value of the simulation model exceeds the structural deformation threshold.

[0081] In one embodiment, the method for determining the correspondence between the preset construction stage and the structural deformation threshold comprises:

[0082] Based on the construction data of tank top beam frame structure samples at different construction stages, multiple buckling instability conditions are determined;

[0083] Performing numerical simulation on the tank top beam frame structure sample according to the multiple buckling instability conditions to generate a set of structural deformation values;

[0084] The structural deformation threshold corresponding to each construction stage is determined respectively according to the structural deformation value set of each construction stage.

[0086] Determine the corresponding safety margin interval according to each construction stage;

[0089] The structural deformation value is input into the damage identification model, and the damage position of the tank top beam frame structure is output; wherein the damage identification model is obtained by performing damage identification training based on the structural deformation value samples of the tank top beam frame structure under different buckling instability conditions and the corresponding damage position samples.
