The Design And Implementation Of Earthquake Disaster Emergency Rescue Simulation Exercise System

Earthquakes are a kind of highly catastrophic and comprehensive natural disaster.Scientific and reasonable rescue measures and post-intervention can effectively reduce casualties.However,its suddenness makes it necessary to organize earthquake rescue practices in regular times to cultivate and improve the earthquake emergency response capability of relevant rescuers if an efficient and orderly response is to be made.The earthquake disaster emergency rescue simulation exercise system is a rescue simulation exercise software for professionals.According to the user group research and functional analysis,the target users of the earthquake rescue simulation exercise could be roughly divided into the four rescue roles: emergency command,medical rescue,health and epidemic prevention and psychological intervention,which as the clue to simulate the earthquake rescue process.Conduct repeated drills to improve the quality of training through the problem assessment and interactive operation simulation.At the same time,the configuration of the data provides the ability to flexibly control and adjust the tasks of user' s role in the system,so that the rescue solution can be improved according to local conditions.Then based on the results of the requirement analysis,the system functions are described from the three modules which are system function,process control and training task.Then detailed design is carried out for each module to clarify the flow and timing relationship of each function point.The database and cache technology are used to design the data storage structure of the system to provide a safe and efficient data access interface.Finally,Unity3 D and Visual Studio Code are used as development environment to implement the function points of the main module.In addition,the black box test and the Unity Profiler tool were used to test the system from the functional and performance layers to determine whether the system met the design goals.From the results of development and testing,users can choose a role to enter the system,follow the system's pre-set storyline,experience the current role task process,obtain and learn relevant knowledge,practice and master related operations,ultimately achieve training objectives for the current role rescue mission.The system finally passed the pre-set test cases,basically fulfilling the requirements of users,functions and performance,and achieved the expected design goals.In the subsequent development process,the improvement of business simulation and the multi-angle user evaluation system can be further explored.
