FIG. 1 is a schematic diagram of the working steps of the present invention.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, in the process of detecting a steel structure, no matter a project being constructed or a finished project is detected, the construction project is only used as a reference, and the influence of environmental factors on the performance of the steel structure is not considered, so that the influence of severe environment on the steel structure is ignored.
The influence of environmental factors on a steel structure cannot be ignored, but steel structure engineering detection in the traditional sense only aims at whether the steel structure meets the design standard and whether the related performance is normal, and the influence of natural disasters on the steel structure is not considered; such as storm, snow storm, etc., which increase the force to which the steel structure is subjected, may change the properties of the steel structure in conformity with the standards, and thus it is necessary to evaluate the properties of the steel structure in consideration of environmental factors.
Referring to fig. 1, an embodiment of a first aspect of the present application provides a steel structure engineering detection and analysis system, which includes a data analysis module and a data acquisition module connected to the data analysis module;
a data acquisition module: the environment data collected in real time is evaluated in combination with the standard data, and the environment data is forwarded to the data analysis module according to the evaluation result; monitoring data of the early warning area are collected through the data collection device, and the monitoring data are sent to the data analysis module after being subjected to image preprocessing;
a data analysis module: building a BIM model for updating a steel structure according to the construction progress, and determining standard data influencing the performance of the steel structure in the construction project by combining the BIM model; performing simulation analysis according to the received environmental data to determine an early warning area corresponding to the steel structure; and obtaining a detection result by combining the monitoring data corresponding to the early warning area.
The application is mainly composed of two parts: the data analysis module is equivalent to a data processing center and is used for carrying out data processing, such as building a BIM (building information modeling) model of a construction project steel structure according to the construction progress and carrying out simulation analysis to determine an early warning area corresponding to the steel structure; the data acquisition module is mainly used for acquiring data and carrying out operations such as preprocessing and the like on the acquired data.
The data analysis module is in communication and/or electrical connection with the data acquisition module; the data acquisition module is respectively in communication and/or electrical connection with the environmental sensor, the data service center and the unmanned aerial vehicle.
And the data analysis module acquires related data through the data acquisition module so as to complete data processing and feedback. The data acquisition module is connected with various types of data acquisition devices, such as an unmanned aerial vehicle for acquiring steel structure image data, an environment sensor for acquiring environment data, a meteorological data website or a meteorological monitoring platform for acquiring climate early warning data and the like.
The data analysis module in this application confirms standard data according to the BIM model, includes:
acquiring a construction progress in real time; building and updating a BIM (building information modeling) model according to the construction progress, and acquiring structural parameters of a steel structure in a construction project; and (4) determining critical data influencing the performance of the steel structure by combining the structural parameters with the BIM model, and marking the critical data as standard data.
When the construction project begins, the BIM model of steel construction is established promptly, constantly gathers data according to the construction progress in order to update the BIM model, consequently this application carries out steel construction engineering based on the BIM model and detects and all can go on in whole work progress.
After the BIM model is established and updated, structural parameters of the steel structure, such as axial pressure ratio, shear-to-weight ratio, rigidity-to-weight ratio and other data representing the performance of the steel structure, are obtained, and the structural parameters are combined with the BIM model to obtain external force which can be borne by the steel structure, namely critical data, so that the steel structure is influenced to different degrees after the borne external force exceeds the critical data. It should be noted that the critical data or the standard data is used as a basis for determining whether the steel structure is affected, and the corresponding value is generally small, and if the steel structure is broken when the external force is 100, and the steel structure is vibrated when the external force is 1, the external force 1 can be used as the critical data.
It can be understood that the higher the completion degree of a construction project is, the smaller the corresponding critical data or standard value is theoretically, and therefore the bearing capacity of the steel structure is larger and larger. The standard data comprises temperature, humidity, pH value, wind power and the like.
The data acquisition module in this application gathers environmental data in real time, includes:
acquiring current weather data through a weather data website or a weather monitoring platform; the method comprises the steps that real-time data are collected through an environment sensor to verify current climate data; marking the current climate data passing the verification as environment data; otherwise, performing expansion splicing on the real-time data, and marking the real-time data as environmental data.
The environmental data includes current climate data and climate warning data. The current climate data refers to the environmental data of the area where the construction project is located, which is acquired through an environmental sensor, a meteorological data website or a meteorological monitoring platform, and in consideration of the fact that the data resolution ratio acquired from a data service center is large, the current climate data needs to be verified before use, namely, the current climate data is verified through the environmental sensor, and after the verification is successful, the current climate data is used as the environmental data.
And when the difference between the current climate data acquired by the data service center and the data acquired by the environmental sensor is large, performing extension expansion according to the environmental sensor data to serve as the environmental data.
The evaluation of the environmental data by the standard data and the forwarding of the environmental data according to the evaluation result in the application includes:

Comparing the environmental data with the standard data, if the environmental data exceeds the standard data, judging that the environmental data can influence the performance of the steel structure, and sending the environmental data to a data analysis module for analysis; if the weather early warning data does not exceed the standard data, the weather early warning data in a certain period of time in the future is obtained through the data service center, and the weather early warning data is judged to not affect the steel structure. It should be noted that, considering the construction progress, a certain period of time in the future should not be too long to avoid the inconsistency between the weather early warning data and the construction progress.
The data analysis module in this application carries out analog analysis to the steel construction according to received environmental data, confirms the early warning region, includes:
simulating environmental data, and analyzing the performance influence degree of the steel structure in the simulated environment in real time; and determining an early warning area according to the performance influence degree and the association influence rule.
The data analysis module simulates external force generated by the environmental data or the environmental data to a BIM model, judges which part of steel structure can be influenced under the action of the environmental data to reduce the performance of the steel structure, and the part of steel structure is an early warning area. It is worth noting that after a certain part of steel structure is influenced, then nearby steel structures can be affected jointly and also can be influenced in performance, and therefore the introduced association influence rule indicates the influence relation among the steel structures, namely after a certain part of steel structure is influenced, the area around the steel structure or the area corresponding to the adjacent steel structure which is not influenced is also set as an early warning area.
The data analysis module in this application obtains the testing result according to the monitoring data, includes:
monitoring data corresponding to the early warning area is collected through a data collection device; and analyzing the monitoring data through an artificial intelligence model, acquiring a detection result, and performing detection early warning according to the detection result.
After the early warning area is determined, monitoring data are collected through a data collection device, for example, image data of the early warning area are shot through an unmanned aerial vehicle, performance data of a steel structure of the early warning area are detected through professional equipment, the monitoring data are analyzed through an image recognition technology or an artificial intelligence model (a support vector machine model and a neural network model), a detection result is further obtained, and if the detection result is abnormal, early warning is carried out to ensure that a worker maintains and processes the steel structure of the abnormal part.
