Design And Realization Of Fire Extinguishing Simulation Training System Based On 3D Visualization

In recent years,the process of urbanization in China has been accelerating,and the probability of disaster accidents in urban construction has also shown an increasing trend,and it is characterized by abrupt and severe damage.As a result,the situation faced by firefighting forces during firefighting and rescue work is caused.More complicated,the rescue work is even more arduous.The concrete manifestations are: the difficulty of disposal is greater,the combat time is longer,and the technical level is more demanding.The emergence of these difficulties is the fundamental reason why firefighting forces must strengthen their firefighting and rescue capabilities.The traditional fire training methods have become weaker in the improvement of firefighters' ability.Therefore,firefighting training must be changed.Based on the above problems,I designed and developed a fire-fighting and rescue simulation training system that uses the three-dimensional visualization technology to combine the previous training methods based on skills and physical strength with the procedural modes.The main purpose is to further strengthen the targetedness of fire-fighting personnel.The training of effectiveness and effectiveness will promote the improvement of training quality by strictly implementing specified training tasks and organizational assessments.The system is based on the concept of three-dimensional visualization technology,under the support of the Visual studio 2016 development tools,the system development,and the use of SQL Server 2016 design and implementation of the database structure to ensure the safety and stability of the system data.First of all,it gives an overall overview of the fire fighting and rescue simulation training system.From the perspective of the system user requirements,the detailed requirements for each function of the system are displayed in the form of a module use case diagram,and the non-functional requirements of the system are briefly explained.Secondly,based on the construction of system technology architecture,hardware architecture and functional module structure,the functional design of the system is demonstrated by using timing diagrams,and the system database design is completed through entity attribute analysis.For the 3D model building of the system,the 3DS Max 3D modeling tool is used to model the 3D scene,and the data model and algorithm set by the system are used in combination with the fire threat situation classification conceptto display and update the fire situation and strive to simulate the training system.The three-dimensional environment is truly sensible.Among them,the fire situation data model can be based on simulated fire field measured data,such as temperature,smoke concentration,etc.,to the situation of the fire field,so as to provide decision support for fire fighting and rescue.Finally,through combing the system development process,the system implementation process is described and the interface diagram is displayed.Before the system is put into use,various aspects of the system are tested.The test results meet the expected design.The three-dimensional visualized fire-fighting and rescue simulation training system has been tried out,with a simple interface and convenient operation.The auxiliary firefighters have improved the training quality and the user satisfaction is high.
