Construction Of Sunshine Information Mapping And Management System For Urban Buildings

With the continuous development of society,the increasing number of construction projects,the increasing population density,many changes have taken place in the living environment,and some new contradictions have emerged.Sunshine lighting has become a prominent problem in recent years.At the same time,people pay more and more attention to lighting in living places.Sunshine information mapping of urban buildings provides field data for sunshine analysis and plays a certain auxiliary role in urban planning.At present,data sources are mostly collected by traditional surveying and mapping methods.The model is a simple line drawing model.In practice,data processing and application are also very cumbersome.The final result gives people a weak sense of vision.Three-dimensional dynamic observation can not be realized in software.There is no continuity and reasonable storage and classification of field surveying and mapping data.In the same work area,it is sometimes necessary to repeat the work.The idea of this study is to build a management system to realize three-dimensional sunshine analysis and related planning auxiliary functions,to store and classify surveying and mapping data,and to provide relevant data and basis for planning and design stage.This paper mainly introduces the whole process of sunshine analysis project,and studies the construction and implementation of urban management system.In this paper,the following aspects of work are specifically done:1.Introduces the types,methods and standards of sunshine measurement data acquisition.This paper studies the solutions to the problems encountered in practical surveying and mapping.2.It studies how to judge the impairment of lighting right and how to make subsequent compensation.3.The whole process of the project is analyzed through a practical case.It includes the method of modeling,the operation flow of calculation,the analysis of data,the modification of scheme,etc.4.The construction of management system,the method of building three-dimensional model,the display of three-dimensional landscape and functional modules are studied.It involves sunshine horizon analysis,visual analysis,building spacing analysis,sunshine shadow analysis,planning analysis and so on.
