Description

Technical Field

[0001] The present invention belongs to the technical field of building material management, and relates to an intelligent management method, system and storage medium for building materials. Background Technique

[0002] Steel bars are essential materials in modern architecture and are one of the very crucial materials in building construction. In concrete building projects, steel bars serve as the main load-bearing components, and their quality affects the stability and safety of the building structure. At the same time, it also determines the service life of the subsequent building structure. Therefore, before the steel bars are put into use, it is necessary to monitor and analyze their quality.

[0003] Currently, the methods for analyzing and inspecting the quality of steel bars mainly analyze and inspect the quality of steel bars through manual sampling inspection. Obviously, this analysis method has the following problems:

[0004] 1. The method of manual sampling inspection has problems such as a low sampling ratio, a high risk of missed inspection, and a high degree of contingency. It cannot intuitively display the quality analysis results of each steel bar, cannot guarantee the accuracy and authenticity of the subsequent sampling inspection quality, and cannot reduce the workload and inspection cost of personnel. Furthermore, it cannot increase the work efficiency and effect of steel bar quality analysis. At the same time, the method of manual sampling inspection also has a problem of strong subjectivity and cannot provide reliable and objective data for the subsequent quality analysis of steel bars.

[0005] 2. The current performance analysis of steel bars requires destructive testing of the steel bars. After the testing, the steel bars will be damaged to a certain extent, reducing the utilization rate of the steel bars, thus causing waste of resources. Moreover, it cannot guarantee the comprehensiveness of steel bar performance monitoring, there are certain differences, and destructive testing is not applicable to the steel bars to be used on the construction site, affecting the construction progress and subsequent construction quality of the building project.

[0006] 3. The current detection of the apparent information of steel bars is a conventional detection, and the analysis process is relatively general and rough. It cannot achieve the comprehensive detection and analysis of the apparent information of steel bars, and thus cannot guarantee the accuracy of the subsequent analysis results.

[0008] To achieve the above purpose, the first aspect of the present invention provides an intelligent management method for building materials, and the method includes the following steps:

[0009] Step 1.

Among them, the basic information includes specification information and material information. The specification information includes appearance information, transverse rib information, and longitudinal rib information;

If the current basic compliance index of the actually purchased steel bars within the specified construction site is less than the set standard actual procurement compliance coefficient, it is determined that the currently actually purchased steel bars within the specified construction site are unqualified, and step 6 is executed.

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of 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.

[0052] The embodiments of the present invention are as Figure 1 shown. An intelligent management method for building materials, the method includes the following steps:

[0053] Step 1.

Among them, the basic information includes specification information and material information, and the specification information includes appearance information, transverse rib information, and longitudinal rib information;

[0054] In a specific embodiment, the appearance information includes dimensions, camber, number of cracks, depth of each crack, number of bumps, and height of each bump. The transverse rib information includes the number of transverse ribs, height of each transverse rib, and spacing between each transverse rib. The longitudinal rib information includes the longitudinal rib width and longitudinal rib height. The material information includes iron content, carbon content, and silicon content.

[0055] It should be noted that the dimensions include diameter, length, area, etc.

[0056] In a specific embodiment, the specific acquisition process of the basic information of steel bars is as follows:

[0057] Install a camera above the area where steel bars are placed in the specified construction site, collect the three-dimensional images of the currently actually purchased steel bars through the camera, and then locate the current actual number of steel bars purchased and the three-dimensional images corresponding to each actually purchased steel bar;

[0081] Step Four: Analysis of steel bar performance information: Analyze the performance of each actually purchased steel bar according to the performance information corresponding to each actually purchased steel bar in the specified construction site;

[0082] In a specific embodiment, the performance of each actually purchased steel bar is analyzed, and the specific analysis process is as follows:
