Abstract

The invention belongs to the technical field of cultural relic protection and building information models, and discloses a daily management and disease control system and method for ancient city walls constructed based on BIM scenes. The existing disease management and control system has the problems that urban wall occurrence environments, repair histories, lack of multi-disease collaborative analysis and the like are difficult to comprehensively consider. According to the invention, by introducing unstructured nodes, environmental factors such as a drainage system, vegetation coverage, underground facilities and internal space are brought into a city wall management system, and the cooperative expression of a city wall structure and an occurrence environment is realized on the basis of structural partitioning. The system takes the urban wall partition number as a unified index, fuses monitoring data, disease information and repair records, realizes space visualization and information linkage by depending on a BIM scene, and simultaneously sets a threshold management mechanism, when the state parameter of an unstructured node reaches a threshold, a corresponding maintenance protection scheme is triggered, so that urban wall information management, dynamic disease monitoring and scientific repair decisions are realized.

Description

Ancient city wall daily management and disease management and control system and method based on BIM scene construction Technical Field The invention relates to the technical field of cultural relic protection and building information models, in particular to a system and a method for daily management and disease control of ancient city walls constructed based on BIM scenes. Background The ancient city wall is taken as an important component of the immovable cultural relics in China, carries rich historical cultural information and is an important substance carrier for continuation and inheritance of Chinese civilization. With the transition of the times, the strategic functions of urban walls as military defense facilities and urban space limiting means are gradually weakened, and the historic, cultural and landscape values of the urban walls are increasingly outstanding. However, due to the restriction of factors such as long time of construction, natural environment change, artificial activity influence and the like, many ancient urban walls are in complex occurrence environments for a long time, and the problems of different degrees of diseases such as denudation, cracks, deformation, local collapse and the like generally occur, so that serious challenges are brought to the safety and continuous protection of cultural relics. In the prior art, the protection work for ancient urban walls is mostly focused on nondestructive detection and monitoring of single disease types, for example, disease data are obtained through crack monitoring, settlement observation or local structure detection and other means, the development trend of urban wall diseases is judged by combining experience of site protection experts, and corresponding protection or repair measures are adopted according to the severity of the diseases. The method can reflect the local disease state of the urban wall to a certain extent, but has obvious limitations on the whole. On one hand, the existing technology is difficult to incorporate the occurrence environment factors of the urban wall into a unified management and analysis framework. The generation and development of urban wall diseases are often closely related to non-structural environmental factors such as drainage conditions, vegetation growth, underground facilities, internal cavities and the like, but in a traditional management mode, the environmental factors exist in a scattered record or experience judgment mode, and cannot be related to an urban wall structure information and disease data formation system, so that disease cause analysis is incomplete and risk identification is delayed. On the other hand, there is a lack of effective comprehensive analysis mechanisms between repair history and multiple types of diseases. The repair modes, materials and processes in different historical periods can continuously influence the urban wall structural performance and the subsequent disease development, but related information is often stored in a scattered manner, and is difficult to compare and analyze with the current disease data. Meanwhile, urban walls usually have multiple disease types at the same time, the mutual influence relationship is complex, in the prior art, single disease and single index analysis modes are mostly adopted, and the cooperative evaluation of multiple diseases is difficult to realize, so that the accuracy of disease prediction and the reliability of safety and stability evaluation results are influenced. In addition, the existing urban wall management means have defects in the aspects of information integration and visualization. Disease data, monitoring information, environmental information and repair records are mostly managed in a scattered manner in a text or table form, visual association with urban wall space entities is lacking, information calling efficiency is low, management staff is difficult to timely and comprehensively master the integral state of the urban wall, and daily management and scientific decision making are not facilitated. In view of the foregoing, there is a need to develop a system capable of visually expressing the occurrence environment of the ancient city wall and comprehensively counting and managing various attribute information, environmental factors, repair history and various diseases of the city wall. Disclosure of Invention The invention aims to provide a daily management and disease control system and method for ancient city walls constructed based on BIM scenes, which are used for solving the problem that the background technology is difficult to comprehensively consider the occurrence environment, the repair history and the cooperative analysis of multiple diseases of the city walls, and realizing the integrated management of the city wall information, the dynamic monitoring of the diseases and scientific decision. The invention mainly adopts the design concept that the ancient city wall block management is taken as
