Description

Digital examination and control method and system for urban high-strength sheet area Technical Field The invention relates to the technical field of urban digital management, in particular to a digital examination and control method and system for urban high-strength areas. Background Along with the gradual development and construction of urban high-strength areas, the urban high-strength area management and control objects gradually enter a fine treatment stage, and the areas management and control objects show the characteristics of multiple bodies, multiple elements and multiple processes. The multi-main body at least comprises planning, construction, operation and maintenance management and other participants, the multi-element at least comprises space morphology, index constraint, facility parameters and other contents, and the multi-process at least comprises scheme demonstration, construction implementation, operation and maintenance management and other stages. Under the background, the urban management activities have higher requirements on the digital supporting capability, so that the display and inquiry of the planning and design results of the region are needed, continuous verification of related rules, indexes and spatial relations is needed, and a unified data base is provided for subsequent rechecking, trace remaining and circulation. The existing digital platform has made a certain progress in GIS display, three-dimensional visualization and data convergence. In engineering practice, a representative platform at home and abroad usually adopts a technical path of multi-source data access, GIS/3D visualization and thematic analysis. The platform is used for integrating and publicly inquiring all-dimensional planning information, realizing transparent display of planning information and regulation information by integrating multisource information such as city general rules, design guidelines, historical protection and property, and the like, carrying out high-precision space simulation and thematic analysis on the other type of platform, carrying out auxiliary evaluation on specific scenes by on-line geometric analysis, line-of-sight analysis, sectioning analysis, thematic models such as traffic, environment and the like, and enhancing urban information display and public participation capacity by means of digital twinning, augmented reality or public neighborhood building data and the like by focusing on historical hierarchy tracing and social perception interaction. Most of the above technologies are still focused on information presentation, thematic query or specific scene simulation, and limited in terms of automated review oriented to high-intensity patch complex rule constraints. On one hand, the existing information system has the common problems of distributed and heterogeneous knowledge data and insufficient cross-stage information connection, text data, model data and rule data from different sources are difficult to form a unified, continuous and reusable data system, on the other hand, the existing scheme still has the defects in the aspects of standardized examination execution and complex scene fast decision, and the existing scheme always needs to rely on manual data retrieval, offline analysis and result feedback again, so that the key problems are not timely identified, the comprehensive comparison cost is high, and the situations of low examination efficiency, insufficient examination consistency, incomplete mark and the like are easy to occur under a multi-main collaborative scene. Related researches also indicate that the urban digital twin technology generally faces the problems of complex data management, insufficient system interoperation, weak social perception dimensionality, weak cross-domain coordination capability and the like in practical application. In addition, in the high-intensity patch planning design examination scene, the object to be examined is not usually single text information or single two-dimensional drawing, but simultaneously relates to a planning design three-dimensional model, layer information, object attribute information and a rule set corresponding to planning control indexes and space relation constraint. The existing scheme generally lacks a technical architecture capable of uniformly organizing and processing model semantics, examination rules and result output, and is difficult to consider object identification, rule detection, result summarization, visual feedback and subsequent review and circulation requirements in the same flow. Therefore, how to improve the continuity, uniformity and traceability of the inspection process in the digital management and control scene facing to the urban high-strength area is still a problem to be further perfected. Disclosure of Invention The invention provides a digital examination management and control method and system for urban high-strength areas, which are used for solving the problems that kn
