VR Training and Assessment System for Hazard Source Identification by Underground Winch Operators

System Content:

The hazard identification module for underground winch operator operations includes:

1. Failure to check the winch fixation before operation

2. Failure to check winch signals before operation

3. Lifting load exceeding the breaking strength of the wire rope

4. Failure to fully engage the speed change handle when using a dual-speed winch

5. Failure to issue startup signals

6. Starting the winch while personnel are present in the ropeway

7. Forcibly pulling and breaking the wire rope during winch material handling

8. Loose winch rope clamps or excessively short mother rope

9. Use of unqualified connecting pins

10. Irregular winch rope arrangement

11. Operating the winch with one hand while attempting to handle rope climbing with the other

12. Leaving excessive residual rope during slackening operations

13. Simultaneous tightening of both brake handles

14. Slackening the winch without power

15. Untimely stopping after the vehicle passes the gradient change point during lifting

16. Forcibly resetting derailed mine cars using the winch

17. During winch operation

System Functions:

1. User login authentication;

2. The system includes training mode and assessment mode. In assessment mode, the system can submit user evaluation results to the backend management system;

3. Supports user interaction with virtual equipment in the virtual environment through VR controllers;

4. Enables users to navigate through the system using controller operations;

5. The system provides text and voice prompt operations;

6. Implements six degrees of freedom (6DoF) interaction with VR controllers in realistic 3D scenes.

Technical Approach:

The system is developed using the Unreal Engine, leveraging PBR materials for realistic virtual reality rendering of underground working environments. Particle systems are employed to simulate effects such as water spraying and dust during operations.
