[0134] In the formula, ln represents the logarithmic function, represents the complex interaction between the physical properties and attenuation of building materials under the influence of the external environment, reflects the non-linear relationship between the physical component performance index sii of building materials and the building material attenuation and deterioration index mfd, and performs a smoothing adjustment on the comprehensive performance index of building materials.

[0135] The durability performance evaluation unit is used to preset a fatigue damage attenuation threshold B according to the service life standard of building materials in the architectural engineering design, and evaluate the durability performance of building materials by comparing it with the obtained comprehensive fatigue durability index fdc. The specific evaluation scheme is as follows;

[0136] When the comprehensive fatigue durability index fdc > the fatigue damage attenuation threshold B, the durability performance of the building materials meets the standard, and normal monitoring is maintained;

[0137] When the comprehensive fatigue durability index fdc ≤ the fatigue damage attenuation threshold B, the durability performance of the building materials does not meet the standard. At this time, a durability risk warning message is generated and transmitted to the relevant personnel's user terminal device through the communication network to notify the replacement of the building materials.

[0138] In this embodiment, through the collaborative work of the comprehensive fatigue analysis module, the fatigue durability analysis unit, and the durability performance evaluation unit, a comprehensive evaluation of the long-term durability of building materials is provided. The fatigue durability analysis unit summarizes and calculates the comprehensive fatigue durability index fdc based on the physical component performance index sii of the building materials and the building material attenuation deterioration index mfd, reflecting the complex interaction between the physical properties and attenuation of the building materials under the influence of the external environment, and smooths and adjusts the comprehensive performance index of the building materials through a logarithmic function. Compared with the traditional single fatigue evaluation method, the comprehensive fatigue durability index can comprehensively consider different environmental factors and attenuation effects of building materials during long-term use, providing a more comprehensive and accurate performance prediction. In addition, the durability performance evaluation unit presets the fatigue damage attenuation threshold B according to the service life standard of the designed building materials in the construction project, and evaluates it with the comprehensive fatigue durability index fdc. In this way, when the durability performance of the building materials does not meet the standard, the system can generate a durability risk warning message in advance and notify the relevant personnel to replace the building materials in time, avoiding potential safety hazards caused by the fatigue aging of the building materials. This module greatly improves the safety and reliability of building materials during long-term use and ensures the sustainability of the project quality.

[0141] The batch management unit is used to record the production information, laboratory test reports, and transportation status of each batch according to the manufacturer's building material performance files, and systematically archive the analysis results of the building material data analysis platform. During the use of building materials, construction personnel will scan the QR code and barcode of the building materials, and the building material data analysis platform will automatically record the use location, construction time, and use status of the building materials;

[0142] The tracking and tracing unit is used to, after a quality problem occurs, first, locate the building materials with quality problems based on the building material usage locations recorded by the building material data analysis platform; second, trace back to the production, transportation, suppliers, laboratory test reports, and transportation links of the building materials through the unique batch numbers assigned to each building material by the manufacturer during production; finally, the building material data analysis platform generates quality traceability information and transmits it to the relevant personnel's user terminal devices through the communication network.

[0143] In this embodiment, the traceability management module realizes the precise tracking and management of the entire life cycle of building materials through the collaborative work of the batch management unit and the tracking and tracing unit, significantly improving the efficiency of quality control and problem solving. The batch management unit records the production information, laboratory test reports, and transportation status of each batch, and automatically records the usage location, construction time, and status of the building materials by scanning QR codes or barcodes. This process enables the real-time tracking of the transfer information of building materials, ensuring the traceability of each batch of building materials from production to use. Especially when a quality problem occurs, the tracking and tracing unit can quickly locate the problematic building materials based on the records of the building material data analysis platform and trace back to its production, transportation, suppliers, and other links according to the unique batch number. Compared with traditional quality control methods, the system not only improves the transparency and accuracy of information but also shortens the time for problem response and solution, greatly enhancing the real-time and refined level of quality management. This efficient traceability function ensures that quality problems can be quickly located and solved, thereby reducing potential risks and guaranteeing the overall quality and safety of the project.
