System Content:

The hazard identification module for underground electrician operations includes:

1. Not wearing qualified insulation protective equipment

2. Failing to install a qualified grounding wire on electrical equipment

3. Bypassing overcurrent and leakage protection of electrical equipment

4. Failure to power off and lock out

5. No warning sign posted on de-energized switches

6. Failure to securely crimp terminal connections of electrical equipment

7. Using timed power on/off arrangements

8. Before maintaining electrical equipment

9. Disconnecting power under load during electrical equipment maintenance

10. Transporting energized electrical equipment

11. Not wearing qualified insulation protective gear

12. Testing high-voltage cables with meters

13. After completing maintenance of high-voltage electrical equipment

System Features:

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 prompts for operations;

6. The system supports 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 to create a realistic virtual reality representation of the underground working environment. Particle systems are used to simulate effects such as water spray and dust during operations.
