The Design And Implementation Of Mental Patient Emergency Response Training System Based On VR Technology

With the continuous development of computer technology and graphics technology,the use of virtual simulation technology to solve various types of complex problems has slowly entered the field of vision,such as emergency rescue,virtual driving,urban planning,virtual training,games and other fields.Especially in the field of virtual training,virtual simulation technology is widely used.Traditional police training has shortcomings such as high training cost,complex police situation,and difficulty in ensuring the safety of trainers.It is difficult to meet the training needs of modern police personnel.Computers are used to simulate the occurrence of police situations and deal with them Staff training has become a more efficient and convenient way.Based on the background of police officers to properly handle the mental situation of mental patients,this article develops a virtual training system for police officers.Police officers will be able to experience the entire training from receiving the police to the proper disposal of the police situation through this system.Process.Thereby greatly reducing the training cost of police personnel and improving the police handling ability.After user research and analysis of experimental content,the results of demand analysis are made.Based on VR technology,the psychiatric patients’ emergency training system for psychiatric patients mainly simulates the aspects of receiving the police,preparing for the police,and going to the scene of the police for proper disposal.The police personnel need to complete the task operation in these processes,so as to improve their awareness of police disposal.According to the needs analysis and analysis results,the system is divided into four major modules: system settings,UI interface management,business foundation,and training tasks,and then the four modules and the functions under each module are designed separately.Finally,My SQL is used to perform system database Detailed design.The system uses the Unity3 D engine and Microsoft Visual Studio 2017 as development tools,uses the Steam VR SDK and VRTK plug-in to assist in the content and functions of virtual reality,uses the Scut server engine to implement the server-side functions of the system,and uses the My SQL database Store the data of this system.This system has been fully tested to meet the training needs of police personnel for handling police situations.Through this system,police situation training can improve the police officers’ awareness of handling police situations,and at the same time can significantly improve the knowledge and skills of police officers and reduce training costs.
