[0018] In order to better understand the above technical scheme, the technical scheme of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0019] See also Figure 1 , shows a BIM-based steel structure stability verification method, which may include the technical solutions described in the following steps S201-S203.

[0020] S201: Obtaining stability data of a steel structure to be analyzed and a steel connection structure corresponding to the stability data of the steel structure to be analyzed, wherein the steel connection structure is used to record a first target steel deployment status associated with the stability data of the steel structure to be analyzed.

[0021] In a possible implementation example, the obtaining of the stability data of the steel structure to be analyzed and the steel connection structure corresponding to the stability data of the steel structure to be analyzed includes: constructing a three-dimensional space coordinate system, projecting the obtained stability data of the steel structure to be analyzed into the three-dimensional space coordinate system, and obtaining the steel connection structure.

[0022] For example, the stability data of the steel structure to be analyzed is obtained through structural calculation through BIM, and the data is obtained after the relevant technical personnel model the data in BIM and input the corresponding parameters for structural settlement. Among them, BIM technology is a data-based tool used in engineering design, construction, operation and maintenance management. It integrates the relevant information of various projects through parameter models, and shares and transmits them during the entire life cycle of project planning, operation and maintenance, so that engineering and technical personnel can correctly understand and efficiently respond to various building information, provide a basis for collaborative work for the design team and all construction entities including building operators, and play an important role in improving production efficiency, saving costs and shortening construction periods.

[0023] S202: Determine, based on the steel connection structure, whether a first target steel deployment situation has established a corresponding first target data queue, and determine whether the steel structure stability data to be analyzed carries a first target tag corresponding to the first target data queue.

[0024] In a possible implementation example, determining whether a corresponding first target data queue is built for a first target steel deployment situation according to the steel connection structure, and determining whether the steel structure stability data to be analyzed carries a first target tag corresponding to the first target data queue, includes: determining a first target steel deployment situation according to the steel connection structure, preprocessing the first target steel deployment situation to obtain a preprocessing result; determining whether to build a corresponding first target data queue according to the preprocessing result, and determining whether the steel structure stability data to be analyzed carries a first target tag corresponding to the first target data queue.

[0025] Among them, steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

[0026] Furthermore, the advantages of steel structure over traditional buildings are: the characteristics of steel are high strength, light weight, good overall rigidity, and strong resistance to deformation, so it is particularly suitable for building large spans, super-high and super-heavy buildings; the material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short; it has a high degree of industrialization and can be produced with a high degree of mechanization. Among them, the following can be specifically included: 1. The material has high strength and light weight. Steel has high strength and high elastic modulus. Compared with concrete and wood, its density to yield strength ratio is relatively low. Therefore, under the same stress conditions, the steel structure has a small cross-section, light weight, easy transportation and installation, and is suitable for structures with large spans, high heights, and heavy loads. 2. Steel has good toughness, plasticity, uniform material, high structural reliability, is suitable for bearing impact and dynamic loads, and has good seismic resistance. The internal structure of steel is uniform and close to an isotropic homogeneous body. The actual working performance of steel structure is more in line with the calculation theory. Therefore, the steel structure has high reliability. 3. The manufacturing and installation of steel structure is highly mechanized, and steel structure components are easy to manufacture in the factory and assemble on the construction site. The finished products of steel structure components manufactured by mechanization in the factory are of high precision, high production efficiency, fast assembly speed on the construction site, and short construction period. Steel structure is a structure with the highest degree of industrialization. 4. The sealing performance of steel structure is good. Since the welded structure can be completely sealed, it can be made into high-pressure containers, large oil pools, pressure pipelines, etc. with good air tightness and water tightness. 5. Steel structure is heat-resistant but not fire-resistant. When the temperature is below 150℃, the properties of steel change little. Therefore, steel structure is suitable for hot workshops, but when the surface of the structure is subjected to heat radiation of about 150℃, it must be protected by heat insulation boards. When the temperature is 300℃-400℃, the strength and elastic modulus of steel both decrease significantly, and when the temperature is around 600℃, the strength of steel tends to zero. In buildings with special fire protection requirements, steel structures must be protected by refractory materials to improve the fire resistance level. 6. Steel structures have poor corrosion resistance. Especially in a humid and corrosive environment, they are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly. For offshore platform structures in seawater, special measures such as "zinc block anode protection" are required to prevent corrosion. 7. Low carbon, energy-saving, green and environmentally friendly, and reusable. The demolition of steel structure buildings will hardly generate construction waste, and steel can be recycled and reused.

[0027] It should be understood that a tag is a title of a data set, and a data queue is a storage unit for key attributes of database data. Therefore, if the steel structure stability data to be analyzed is to carry the tag capability for the first target steel deployment situation, the database must first carry a first target data queue for the first target steel deployment situation, and the first target data queue must carry a corresponding tag, and the tag is applied to the steel structure stability data to be analyzed. The first target data queue is used to store the first target steel deployment situation, and the first target tag is used to arrange the first target data queue.

[0028] Based on this, the stability data of the steel structure to be analyzed can be subjected to a compliance check according to the steel connection structure. The compliance check can be used to determine whether the first target steel deployment situation has built a corresponding first target data queue, and whether the stability data of the steel structure to be analyzed carries the first target tag corresponding to the first target data queue, so as to verify whether the stability data of the steel structure to be analyzed can operate stably under the steel connection structure. For example, when the first target steel deployment situation does not carry the corresponding first target data queue, or the stability data of the steel structure to be analyzed does not carry the first target tag corresponding to the first target data queue, it can be determined that the stability data of the steel structure to be analyzed may carry an operating problem, and an inspection report can be output to relevant personnel for analysis, or automatic repair can be performed based on the inspection report.

[0029] S203: In response to the first target steel deployment situation not building a corresponding first target data queue, or the steel structure stability data to be analyzed does not carry the first target tag, it is determined that the steel structure stability data to be analyzed does not meet the steel connection structure.

[0030] Exemplarily, in response to the first target steel deployment situation, the corresponding first target data queue is not established, or the steel structure stability data to be analyzed does not carry the first target tag, and it is determined that the steel structure stability data to be analyzed does not meet the steel connection structure.

[0031] When the steel structure stability data to be analyzed has the above problems, it will cause the steel structure stability data to be unable to verify the first target steel deployment status through the tag during operation, thereby failing to meet the requirements of the steel connection structure for the steel structure stability data. The compliance inspection of the steel structure stability data to be analyzed can be completed in this way.

[0032] Furthermore, when performing a key attribute inspection, the stability data of the steel structure to be analyzed can be obtained first, as well as the steel connection structure corresponding to the stability data of the steel structure to be analyzed. The steel connection structure can identify the first target steel deployment situation associated with the key attribute to be analyzed. That is, in order for the stability data of the steel structure to be analyzed to operate normally under the steel connection structure, it is necessary to carry a label for the first target steel deployment situation. Based on the steel connection structure, it can be determined whether the first target steel deployment situation has built a corresponding first target data queue, and whether the stability data of the steel structure to be analyzed carries the first target label corresponding to the first target data queue, so that the inspection of the stability data of the steel structure to be analyzed can be automatically completed, and the analysis can be obtained to determine whether the stability data of the steel structure to be analyzed can operate stably, thereby ensuring the accurate determination of the structural stability, thereby ensuring the safety of the building.

[0033] It should be understood that in the log information waiting to be analyzed, there may be several identical steel structure stability data in the source of steel structure stability data. In one possible implementation, in order to improve the efficiency of key attribute inspection, several original steel structure stability data can be obtained first, and then the BIM calculation instructions corresponding to the several original steel structure stability data can be determined. The BIM calculation instructions correspond to the steel structure stability data one by one, and the BIM calculation instructions corresponding to the same original steel structure stability data are the same. Based on this, the steel structure stability data can be deduplicated through the BIM calculation instructions, that is, for each BIM calculation instruction, a unique original steel structure stability data can be obtained and determined as the steel structure stability data to be analyzed, thereby avoiding overlapping inspections for the same steel structure stability data and improving the efficiency of key attribute inspections.

[0034] In a possible implementation, in order to improve the stability of the steel structure stability data, the problematic steel structure stability data to be analyzed can also be actively debugged. For example, a candidate tag corresponding to a key attribute of the data to be analyzed can be determined, and the candidate tag is a first target tag not carried in the steel structure stability data to be analyzed. The candidate tag can be added to the steel structure stability data to be analyzed, thereby further ensuring the stable operation of the steel structure stability data to be analyzed.

[0035] In addition, since the steel connection structure may be optimized, in order to improve the accuracy of key property inspection through the steel connection structure, when the steel connection structure is obtained, it can be analyzed whether the steel connection structure is the latest steel connection structure.

[0036] In addition to compliance inspections, a variety of different key attribute inspections can also be performed. For example, in one possible implementation, the second target tag required for the steel structure stability data to be analyzed during operation can be determined. The second target tag is a tag that should be added in order to enable the steel structure stability data to be analyzed to operate more stably and efficiently. It should be understood that the second target tag is different from the first target tag, and may not be a tag that must be carried by the steel structure stability data to be analyzed for operation, but may be a tag that can be added to improve the performance of the steel structure stability data to be analyzed. It can be checked whether the second target tag is included in the steel structure stability data to be analyzed, so as to check whether the key attribute of the operation to be analyzed carries a higher operating performance. That is, if the steel structure stability data to be analyzed includes the second target tag, it carries a relatively higher operating performance; if it is not included, the operating performance is poor.

[0037] In addition, there may be some key attribute data with a small scale in the database. When building labels for these key attributes, the database will arrange all the key attributes of the labels. However, due to the small data scale of these key attributes, the arrangement is less useful, which will cause a certain waste of processing resources. Based on this, in order to further optimize the data processing time, in a possible implementation, a third target label included in the steel structure stability data to be analyzed can be obtained. The third target label is the label involved in the operation of the steel structure stability data to be analyzed. Subsequently, the deployment of the steel to be analyzed corresponding to the third target label can be determined. In response to the data scale in the deployment of the steel to be analyzed being less than the pre-set target value, it means that the data scale of the deployment of the steel to be analyzed is small and does not need to be arranged through labels. At this time, the third target label can be removed, thereby reducing the data processing time.

[0038] In addition to the above-mentioned key attribute inspection based on the dimension of the steel structure stability data to be analyzed, the key attribute inspection can be further performed based on the dimension of the database queue. In a possible implementation, the queue data corresponding to the steel structure stability data to be analyzed can be obtained, and the queue data is used to record the second target data queue involved in the steel structure stability data to be analyzed, and then the performance inspection of the steel structure stability data to be analyzed is performed based on the queue data.

[0039] Specifically, the performance test can include two aspects: on the one hand, it can be used to check whether the queue data carries overlapping or redundant tags; on the other hand, it can be used to check whether the queue data carries tags that have not been verified by the stability data of the steel structure to be analyzed. As mentioned above, the database will arrange all tags when it is running. Since redundant tags and unverified tags are most likely to be removed, checking such tags will help further optimize data processing time.

[0040] In a possible implementation, it can be determined whether the second target data queue carries a key attribute with an overlapping label, that is, a plurality of labels are set up for the key attribute, so when the database is running, the key attribute will be arranged in an overlapping manner, wasting database resources. In response to the key attribute with an overlapping label being carried in the second target data queue, abnormal data for the second target data queue can be generated to indicate that there is a label problem in the queue.

[0041] It is possible to determine whether the tags corresponding to the second target data queue carry unverified tags based on the tag verification data. In response to the tags corresponding to the second target data queue carrying unverified tags, abnormal data for the second target data queue can also be generated. For example, a tag verification inspection tool can be used to check whether there are unverified tags in the output. Of course, as mentioned in the aforementioned scheme, due to the need to meet the steel connection structure, some necessary tags are required in the steel structure stability data to be analyzed, and these tags may not be verified. Therefore, based on the steel connection structure, it is possible to determine whether there are tags corresponding to the steel connection structure among the unverified tags determined. If so, the abnormal data generated based on these tags can be cancelled, thereby reducing the possibility of false alarms.

[0042] It should be understood that there may be sub-libraries and sub-tables in the database, that is, the same queue may be stored in several databases. Under normal circumstances, since the key attribute content and label content of the queue are the same, the number of abnormal data for the queue should be associated with the number of data in the queue, such as consistent or the number of abnormal data is an integer multiple of the number of queues. That is, if the second target data queue includes several, several second target data queues are the same queues deployed in different databases, in response to the number of abnormal data for the second target data queue being not associated with the number of the second target data queue, it means that erroneous abnormal data has occurred therein, and the abnormal data can be cleaned.

[0043] Among them, the reasons for the uncorrelated number of abnormal data in different situations may be different. For example, when checking for overlapping or redundant labels, the number of abnormal data is uncorrelated with the number of queues. This may be because when optimizing the queues, the optimization is not performed for all identical queues, resulting in the optimization of key attributes and labels in some queues, while the optimization of key attributes and labels in some queues is not performed, resulting in overlapping labels in some queues and non-existence in some queues. For the inspection of unverified labels, it may be because the operation progress of different databases is different, resulting in the labels in some queues being verified, while the same labels in other queues have not been verified, resulting in the generation of abnormal data for unverified labels in some queues.

[0044] On the basis of the above, a BIM-based steel structure stability verification device is provided, the device comprising:

[0045] A data acquisition module, used to obtain the stability data of the steel structure to be analyzed, and a steel connection structure corresponding to the stability data of the steel structure to be analyzed, wherein the steel connection structure is used to record the first target steel deployment status associated with the stability data of the steel structure to be analyzed;

[0046] a tag determination module, used to determine, in combination with the steel connection structure, whether the first target steel deployment situation has established a corresponding first target data queue, and to determine whether the steel structure stability data to be analyzed carries a first target tag corresponding to the first target data queue, the first target data queue being used to store the first target steel deployment situation, and the first target tag being used to arrange the first target data queue;

[0047] The stability determination module is used to determine that the stability data of the steel structure to be analyzed does not meet the set stability requirements in response to the first target steel deployment situation not building a corresponding first target data queue, or the stability data of the steel structure to be analyzed does not carry the first target tag.

[0048] On the basis of the above, a BIM-based steel structure stability verification system is shown, including a processor and a memory that communicate with each other, and the processor is used to read and execute a computer program from the memory to implement the above method.

[0049] Based on the above, a computer-readable storage medium is also provided, on which a computer program stored implements the above method when running.

[0050] In summary, based on the above scheme, when conducting key attribute inspection, the stability data of the steel structure to be analyzed can be obtained first, as well as the steel connection structure corresponding to the stability data of the steel structure to be analyzed. The steel connection structure can identify the first target steel deployment situation associated with the key attribute to be analyzed. That is, in order for the stability data of the steel structure to be analyzed to operate normally under the steel connection structure, it is necessary to carry a label for the first target steel deployment situation. Based on the steel connection structure, it can be determined whether the first target steel deployment situation has built a corresponding first target data queue, and whether the stability data of the steel structure to be analyzed carries the first target label corresponding to the first target data queue, so that the inspection of the stability data of the steel structure to be analyzed can be automatically completed, and the analysis can be obtained to determine whether the stability data of the steel structure to be analyzed can operate stably, thereby ensuring the accurate determination of the structural stability, thereby ensuring the safety of the building.
