铁路信号基础设备虚拟仿真实验设计与应用

Design and Application of Virtual Simulation Experiment for Railway Signal Basic Equipment

针对学生在铁路信号基础设备实验教学过程中存在时间和场地受限、设备类型不全、过程难监控等问题,根据“以虚补实、虚实结合”的指导思想,应用虚拟现实技术设计开发了信号机、转辙机、轨道电路等多种类型的信号基础设备虚拟仿真实验教学资源,包含部件拆解、动作原理模拟、电路原理动态展示、常见故障维护等多种实验模块,教学内容多样,教学方法新颖,教学手段丰富。学生在线完成线下难以开展的实验教学任务,取得了良好的教学效果,切实解决了实体实验“做不了、做不上、做不好”的问题,为培养学生实践能力及创新能力提供了有力支撑。

In view of the problems existing in the experimental teaching of railway signal basic equipment,such as limited time and site,incomplete equipment types and difficult process monitoring,according to the guiding ideology of"supplementing virtual reality with virtual reality and combining virtual reality",various types of virtual simulation experimental teaching resources of signal basic equipment such as annunciator,switch machine and track circuit are designed and developed by using virtual reality technology.It includes a variety of experimental modules such as component disassembly,action principle simulation,dynamic display of circuit principle and common fault maintenance.The teaching contents are diverse,the teaching methods are novel and the teaching means are rich.Students have completed the experimental teaching tasks that are difficult to carry out offline online,achieved good teaching results,effectively solved the problem of"unable to do,unable to do,and unable to do well"in physical experiments,and provided strong support for cultivating students’practical ability and innovation ability.
