Circuit Diagram Module: This module showcases the dynamic working process of electrical circuits in a three - dimensional environment. It includes over a hundred circuit diagrams and demonstrates the dynamic power - on and power - off processes of the vehicle's electrical system. The actions throughout the entire process are clear, and all power - on and power - off processes are completely consistent with the actual working processes of the subway company's vehicles.

Assembly Diagram Module: It contains typical three - dimensional wiring diagrams of the electrical system, along with the connection methods and positions of the wiring, which serve as the positioning points for students' maintenance training.

Demonstration in a Three - Dimensional Virtual Simulation Environment: The demonstration process is realized using dynamic three - dimensional virtual simulation technology. The proportional relationships and materials of all components are exactly the same as those of the physical objects. All components can be viewed from 360 degrees, and the working process is dynamically displayed.
