Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0039] With the increasing demand for liquefied natural gas year by year, higher requirements are also put forward for the storage capacity of liquefied natural gas. Generally, liquefied natural gas is stored in storage tanks, so the stability of the dome structure of the storage tank is crucial. However, at present, it is impossible to detect whether there is damage to the dome structure of the storage tank, and it is difficult to determine the health status of the storage tank, resulting in risks in the storage of liquefied natural gas. To solve the above technical problems, the present invention provides a method, device, equipment, medium, and product for identifying damage to the dome structure of a storage tank, which can effectively determine the damage condition of the dome structure of the storage tank. The technical solutions of the present invention will be described in detail below with specific examples.

[0040] Refer to Figure 1 As shown, a method for identifying damage to the dome structure of a storage tank according to the present invention includes:

[0041] S110. Collect the vertical pressure value acting on the spherical steel dome formwork by the reinforced concrete structure in the dome structure of the storage tank and the current working condition of the dome structure of the storage tank according to the pressure detection device;

[0042] S120. Determine the corresponding target damage identification model according to the current working condition of the dome structure of the storage tank; wherein, the target damage identification model is obtained through damage identification training based on the vertical pressure value samples and the corresponding damage location samples and damage level samples;

[0043] S130. Use the target damage identification model to perform damage identification on the vertical pressure value to determine the damage location and damage level of the dome structure of the storage tank.

[0044] In step S110, by way of example, the storage tank dome structure is spherical crown-shaped and is itself a reinforced concrete structure, which is cast on a pre-installed spherical crown-shaped steel dome formwork. After the installation of the spherical crown-shaped steel dome formwork is completed, it remains permanently and is not removed. The working conditions include typical working conditions such as pressure-holding casting, prestress tensioning, and pneumatic testing.

[0045] The pressure detection device is arranged at the top of the spherical crown-shaped steel dome formwork, and the pressure detection device is a piezoelectric film sensor. The piezoelectric film sensor is a thin film. One large or multiple piezoelectric film sensors are arranged on the spherical crown-shaped steel dome formwork, and the vertical pressure within the range of the piezoelectric film is measured. Specifically, a single or multiple piezoelectric film sensors are arranged on the surface of the spherical crown-shaped steel dome formwork. A single piezoelectric film sensor covers the entire dome range, and multiple piezoelectric film sensors are arranged evenly in a ring shape and are cast inside the concrete, so that the vertical pressure values at different stages of the storage tank dome structure (such as during concrete casting construction and operation stages) can be sensed. The piezoelectric film sensor can send the collected vertical pressure values in real time, or can send the collected vertical pressure values at preset time intervals. The preset time interval is set according to the actual situation and is not limited here.

[0046] In step S120, by way of example, since the damage conditions of the storage tank dome structure under different working conditions are different, corresponding damage recognition models can be trained for each working condition. And the corresponding relationship between each working condition and its corresponding damage recognition model is saved. In this way, after determining the current working condition, the corresponding damage recognition model can be found in the above corresponding relationship as the target damage recognition model.

[0047] Furthermore, for each damage recognition model corresponding to each working condition, first, the vertical pressure value samples under this working condition, as well as the damage position samples and damage level samples under this vertical pressure value sample, are obtained. The vertical pressure value samples and the damage position samples under this vertical pressure value sample are used as training data to train the neural network model to obtain the damage recognition model under this working condition. Among them, the damage position samples can be represented by coordinates. For example, if the damage is a point, the coordinates of this point are used to represent the damage position. If the damage is an area, the coordinates of the corner points of this area can be used to represent the damage position, or the coordinates of the center point of this area can also be used to represent the damage position. The damage level samples are pre-divided according to the actual situation for various damages. For example, the first damage level, the second damage level... the Nth damage level, and the first damage level is the most serious damage situation.

[0048] In step S130, by way of example, the vertical pressure value collected by the piezoelectric film sensor is input into the target damage recognition model for damage recognition prediction, and the model outputs the damage position and damage level of the storage tank dome structure.

[0049] In the technical solution of the present application, the vertical pressure value of the reinforced concrete structure acting on the spherical steel dome formwork in the storage tank dome structure and the current working condition of the storage tank dome structure are collected according to the pressure detection device; the corresponding target damage identification model is determined according to the current working condition of the storage tank dome structure; wherein, the target damage identification model is obtained through damage identification training based on the vertical pressure value samples, the corresponding damage location samples and damage level samples; the target damage identification model is used to identify the damage of the vertical pressure value, and the damage location and damage level of the storage tank dome structure are determined. It can be seen that the damage location and damage level of the storage tank dome structure are predicted according to the vertical pressure value collected by the pressure detection device in combination with the current working condition of the storage tank dome structure, realizing the intelligent identification of the damage of the storage tank dome, so that the safety of the structure of the storage tank dome can be effectively judged at different construction stages, thereby ensuring the safety of the storage of liquefied natural gas.

[0050] In one embodiment, referring to Figure 2 , the method for obtaining the vertical pressure value samples includes:

[0051] S210. Using a preset simulation model to simulate the storage tank dome structure for each working condition of the storage tank dome structure, and obtaining the storage tank dome simulation model under each working condition;

[0052] S220. Generating different types of damages on the storage tank dome simulation model to obtain the vertical pressure value samples of the storage tank dome structure under each working condition.

[0053] Preferably, step S210 includes: using a preset digital twin model and the structural parameters of the storage tank dome structure to simulate the storage tank dome structure to obtain an initial simulation model;

[0054] Performing parameter optimization on the initial simulation model for each working condition of the storage tank dome structure to obtain the storage tank dome simulation model under each working condition.

[0055] Exemplarily, the digital twin model adopted is a high-fidelity digital twin model, which is a three-dimensional refined finite element model, and the physical parameters of each part are selected according to the specification requirements. It should be noted that the initial simulation model includes but is not limited to concrete and steel bars, and the concrete in the initial simulation model is a solid model. The structural parameters include the size of the storage tank dome, etc. The simulation software includes commercial general finite element analysis software or professional finite element analysis software.

[0056] Specifically, the dome of the LNG storage tank is of reinforced concrete structure. The shape and reinforcement of the initial simulation model are the same as those of the actual LNG storage tank dome, but the structural physical characteristic parameters such as density, elastic modulus, and coefficient of thermal expansion are taken according to the specifications, with a large difference from the actual structural parameters. Then, the parameters of the initial simulation model are modified according to the actual working conditions of each working condition of the storage tank dome structure, so that the generated simulation model of the storage tank dome can accurately reflect the actual working conditions of this working condition.

[0057] Furthermore, the parameters of the initial simulation model are optimized for each working condition of the storage tank dome structure to obtain the simulation models of the storage tank dome under various working conditions, including:

[0058] Perform numerical simulation on each working condition of the storage tank dome structure according to the initial simulation model to obtain the model simulation parameters;

[0059] Optimize the initial simulation model using the loss between the model simulation parameters and the preset target parameters to obtain the simulation models of the storage tank dome under various working conditions.

[0060] In this embodiment, first monitor the vertical pressure of the storage tank dome structure in each working condition to obtain the measured vertical pressure result set. Use the initial simulation model to perform numerical simulation on the same working condition. After obtaining the numerical simulation results, compare them with the measured results under the same working condition, adjust the parameter values, and then perform numerical simulation again. Repeat this step until the error between the numerical simulation results and the measured results under the same working condition meets the requirements, and obtain the simulation models of the storage tank dome under various working conditions. The storage tank dome simulation model at this time is a refined digital twin model, and the refined digital twin model is a three-dimensional refined finite element model. In this way, through the parameter optimization of the simulation model, the accuracy of the simulation model is guaranteed.

[0061] Preferably, different types of damages are generated on the storage tank dome simulation model, including:

[0062] According to the method of dividing into rings and segments, multiple sample units are divided on the storage tank dome simulation model, and different types of damages are generated on the multiple sample units.

[0063] Exemplarily, different types of damages include typical damages such as deeper cracks in the dome and significant reduction of elastic modulus due to deterioration of concrete performance. Specifically, using the method of dividing into rings and segments, units with a rectangular radial projection are divided. Different units are sequentially selected and given different types of damages, and numerical simulation is performed to obtain the sample of vertical pressure values of the LNG storage tank dome. And save the sample of vertical pressure values to the simulation database.

[0064] Further, obtain the damage location samples and damage level samples corresponding to each vertical pressure value sample. In this embodiment, the damage identification model under each working condition adopts an artificial neural network algorithm. The damage location samples and damage level samples corresponding to the vertical pressure value samples are formed into a learning mode pair for training the network. The artificial neural network algorithm is used to normalize and dimensionless process the damage location samples and damage level samples corresponding to the vertical pressure value samples in the selected initial learning mode pair, and the final structure is formed into the final training mode pair. Then, the artificial neural network algorithm is used to select an appropriate network topology structure, perform network initialization, establish a convergence criterion, and finally provide the final training mode to the network and train the network until the convergence criterion is met. In this way, the damage identification model under each working condition is output according to the above training. In this way, after the piezoelectric film sensor collects the vertical pressure value of the storage tank dome structure, the damage identification model under this working condition can be used to identify the damage to the vertical pressure value, and the damage location and damage level of the storage tank dome structure under various working conditions can be effectively determined. Thus, it is possible to realize concrete damage identification during the concrete pouring construction stage, correct and optimize the pouring strategy, and ensure construction safety.

[0065] Further, after determining the damage location and damage level of the storage tank dome structure, an alarm message is sent when the damage location or damage level meets the preset damage condition.

[0066] In this embodiment, if the damage location is a key location, or the damage level is the first damage level or the second damage level, it indicates that there is a risk of failure of the storage tank dome structure. Therefore, an information about the risk of failure of the storage tank dome structure is sent to the staff, which can effectively conduct structural early warning and ensure the safety and reliability of the structure.

[0067] The present invention also provides a damage identification device for a storage tank dome structure. Referring to Figure 3 as shown, it includes:

[0080] Perform numerical simulation on each working condition of the storage tank dome structure according to the initial simulation model to obtain model simulation parameters;

[0081] Optimize the initial simulation model by using the loss between the model simulation parameters and the preset target parameters to obtain a storage tank dome simulation model under each working condition.
