The Design And Realization Of The Evacuation Simulation System Of Campus Buildings

With the continuous development of education in our country,the number of university students has increased year by year.Under this background,the ability of schools to evacuate in emergencies has drawn more and more attention from all walks of life.Therefore,early warning of evacuation in schools An important part of school management.Traditional evacuation warnings are mostly conducted in the form of organization of evacuation drills.However,with the continuous improvement of information construction in our country,modern information technology is constantly being integrated into our daily life and changing all aspects of our lives.Through the modernization of information technology,the transfer of traditional campus security evacuation drills to computers has been completed,thereby greatly liberating manpower and material resources,saving the time and cost of evacuation drills and improving the modern management of schools.Therefore,it is necessary to design and implement a crowd evacuation simulation system based on campus buildings.This dissertation uses C / S architecture to design campus building evacuation simulation system,and introduces the system from the aspects of requirement analysis,system design,database design,algorithm model,function realization and system test respectively.Firstly,the commonly used evacuation model is introduced,and the RVO model is introduced emphatically.The system improves the traditional RVO model and incorporates the individual characteristics and density factors,so the CDRVO algorithm is obtained,which makes the simulation evacuation more accordant with evacuation Then,the functional requirements of the system are described by use cases and use-case statistic tables,and the non-functional requirements of the system are analyzed in terms of portability,reliability and security.Secondly,with the help of topology map,flow chart and Function architecture diagram to describe the detailed design and overall design of the system.Afterwards,the database used by the system is modeled and analyzed.The specific fields of each data table and their relations with each other are introduced in the form of ER diagram and table structure.Finally,some system functional interfaces and implementation code are demonstrated,and test cases are designed.Combining the design principles of black box test and white box test,the system is tested for function.In this regard,the completion of the entire campus evacuation simulation system development.The system uses the software engineering modeling ideas and object-oriented development methods,the inherent structure of stability,scalability,thereby reducing the late expansion of the system cost and maintenance costs.The campus building evacuation simulation system finally realized five functional modules of user login and registration,evacuation simulation management,evacuation data analysis,personal information maintenance and system management,which basically fulfilled the functional requirements of evacuation simulation.The system's main features are:(1)All the functions of the system are decomposed and reorganized in detail,and divided into different modules,thereby improving the readability and reusability of the system code and reducing the maintenance cost.(2)Using Qt as a system development tool,with the help of Qt cross-platform features,the system's portability is guaranteed.(3)On the basis of the traditional simulation platform,the system stores the simulation data into the database in real time and performs statistics and analysis on the data in the later period so as to make the system more suitable for the development of evacuation and early warning analysis.(4)The system uses modern information technology to transfer the traditional offline evacuation drills to the online and reduce the cost of exercise,to a certain extent,improve the modern management level of the school.
