Design And Research on 3D Interactive Experiment Case of Virtual Railway Signal Equipment Based on Hardware Perception

With the continuous increase of railway operation mileage, higher requirements are put forward for professionals who can operate and maintain railway signal equipment accurately and skillfully. In the process of practical teaching for employees, due to the characteristics of railway operation, such as fast train running speed, high traffic density, scattered equipment layout and high safety requirements for on-site operation, the traditional practical teaching of railway signal equipment based on on-site observation is difficult for students to master the working principle of equipment, real-time information transmission process, equipment action status, linkage with other equipment, etc. To a certain extent, it limits the cultivation of students’ engineering practice ability and innovation ability. The research has developed a 3D interactive experiment system of virtual railway signal equipment based on hardware perception. Through controlling 3D virtual signal equipment by hardware sensing component, students can know the internal components, composition and operation environment of the equipment at any time, so that they can quickly understand the function of railway signal equipment and understand the actual action principle of signal equipment in railway station.
