基于VRML的虚拟公安派出所仿真实训系统的设计

Design of Virtual Simulation Training System of Police Station Based on the VRML

为提升课程“公安派出所建设”的实践教学质量,设计开发虚拟公安派出所仿真实训系统。学生以第一人称视角在仿真实训系统中完成虚拟派出所场景参观、相关设置标准与功能用途认知实训、常见业务认知实训。利用AutoCAD、3Dmax与VRMLPAD等软件进行虚拟派出所的三维模型建模,应用VRML与内置的Javascript语言设计创新性开发了系统用户交互界面、文本与语音、培训视频播放等交互功能,链接公安接处警业务实训系统。该仿真实训系统拓展了“公安派出所建设”实训教学内容的广度和深度,延伸了实训教学时间和空间,降低了实训成本,提升了教学效率,丰富了治安学专业实践教学模式。

The virtual simulation training system of police station is designed to reinforce the teaching quality of Police Station Construction experiment course.Students are with first-person perspective to accomplish the virtual scene visiting training of police station,the relevant setting standards and functions cognition training of police station,and common service cognition of police station by the simulation training system.Some software as AutoCAD,3Dmax and VRMLPAD are employed to proceed virtual 3D model of police station,the creativity of VRML and Javascript language design are applied to exploit interactive functions as interactive interface,text and voice,as well as training video display for students,together with linking police service training system.The simulation training system has developed the range and depth of the teaching content of Police Station Construction course,extended the time and space of training teaching,reduced the cost of training,promoted the efficiency of teaching,as well as enriched the practical teaching model of public security speciality.
