Description

Technical Field

[0001] This application belongs to the field of electronic data analysis, and specifically relates to a method and system for hierarchical acquisition and analysis of the attribute information of cultural relic buildings. Background Art

[0002] Cultural relic buildings refer to buildings and structures with certain historical, cultural, and scientific values, usually referring to ancient buildings, historical buildings, cultural heritage buildings, etc. These buildings and structures usually have unique architectural styles, techniques, and materials, reflecting the cultural, artistic, technical, and economic characteristics of different historical periods. They are an important part of cultural heritage and various measures need to be taken to protect them from damage. During the protection and maintenance process of cultural relic buildings, it is often necessary to collect and analyze the attribute information of cultural relic buildings. At this time, a method and system for hierarchical acquisition and analysis of the attribute information of cultural relic buildings are required;

[0003] When the prior art performs hierarchical acquisition and analysis of attribute information, it usually only collects the attribute information and cannot perform a quantitative assessment based on the damage situation of the cultural relic building, and cannot judge whether the building needs maintenance according to the quantitative assessment result. Manual judgment is slow and highly subjective. At the same time, it is impossible to perform structural maintenance analysis based on the importance and danger of the structural components before maintenance, and thus it is impossible to accurately judge the maintenance steps. Most of the prior art has the above problems;

[0004] To solve the problems raised in this background art, this application designs a method and system for hierarchical acquisition and analysis of the attribute information of cultural relic buildings. Summary of the Invention

A method for hierarchical collection and analysis of cultural relics and building attribute information as claimed in claim 1, characterized in that: The specific contents of obtaining the historical preservation data of the cultural relic building and the structural composition data of the cultural relic building are as follows: Obtain the historical connection position data of each connection part of the cultural relic construction and the image data of the original connection part after 3D restoration; Use sensors to obtain connection position data and image data of each connection part of the current cultural relic construction; The attribute data of each connection component of the cultural relic building and the number data of other connected components are obtained through sensors, wherein the attribute data includes the original construction connection strength data and the current connection strength data of the connection components.

3. A hierarchical collection and analysis system for cultural relics and architectural attribute information, which is implemented based on the hierarchical collection and analysis method for cultural relics and architectural attribute information as claimed in any one of claims 1 to 2, characterized in that: It specifically includes a data acquisition module, a maintenance judgment module, an importance assessment module, a risk assessment module and a maintenance step sorting module; wherein the data acquisition module is used to acquire the historical preservation data of the cultural relic building and the data of each structural component of the cultural relic building; the maintenance judgment module is used to import the acquired historical preservation data of the cultural relic building into the risk assessment strategy to conduct a risk assessment of the cultural relic building and make a maintenance judgment; the importance assessment module is used to import the data of each structural component of the cultural relic building into the structural component importance assessment strategy to conduct a structural component importance assessment; the risk assessment module is used to acquire the risk situation data of the corresponding structural component of the cultural relic building and import it into the risk assessment strategy to conduct a structural component risk assessment; the maintenance step sorting module sorts the maintenance steps based on the structural component importance assessment results and the structural component risk assessment results.

4. An electronic device, comprising: A processor and a memory, wherein the memory stores a computer program that can be called by the processor; It is characterized in that the processor executes the hierarchical collection and analysis method of cultural relic building attribute information as described in any one of claims 1-2 by calling the computer program stored in the memory.

5. A computer-readable storage medium, characterized in that: Instructions are stored, and when the instructions are run on a computer, the computer executes a hierarchical collection and analysis method for attribute information of cultural relics and buildings as described in any one of claims 1-2.
