System Content:

The hazardous source identification module for roadheader operators includes:

1. Failure to inspect the roadheader cable dragging device

2. Failure to inspect the roadheader cutting head picks

3. Failure to inspect the roadheader internal and external spray devices

4. Failure to inspect the roadheader walking mechanism

5. Failure to check whether the roadheader cooling water pipe is intact

6. Failure to issue the start-up signal

7. Failure to start the bridge conveyor

8. Dealing with hard rock inclusions or pyrite nodules

9. Failure to stop the machine promptly when the roadheader load is abnormal

10. Performing maintenance on the roadheader without disconnecting the isolation switch and cutting off the power

11. Failure to inspect the integrity of the roadheader oil pump and cutting motor locking device

12. Failure to inspect the integrity of the gas monitoring instrument on the roadheader

13. Failure to inspect the roadheader oil tank and cutting reducer

14. Failure to carry the roadheader power handle after shutdown

15. Dust generated during the roadheader cutting and mucking process

System Functions:

1. User login permission authentication;

2. The system is divided into training mode and assessment mode. In assessment mode, the system can submit user assessment results to the backend management system;

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

4. Supports users navigating through the system via controller operation;

5. The system provides text and voice prompt operations;

6. The system enables six degrees of freedom (6DoF) interaction with VR controllers in a realistic 3D scene.

Technical Approach:

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