System Content:

The hazardous source inspection module for scraper conveyor operators includes:

1. Failure to inspect the scraper conveyor

2. Coal retention in the scraper conveyor chute after shutdown

3. Failure to inspect excessive overlap between the scraper conveyor and transfer machine

4. Failure to inspect the connection between the scraper conveyor and the support push-pull cylinder

5. Failure to inspect the integrity of the scraper, scraper chain connecting ring, and chute

6. Failure to issue signals or perform finger-pointing verbal confirmation before startup

7. Failure to inspect roof support conditions at both ends, leading to roof support failure and falling debris causing injury

8. Failure to disconnect the scraper conveyor isolation switch

9. Failure to continuously monitor the operational status of all parts during operation

10. Operator leaving their post during scraper conveyor operation

System Functions:

1. User login and permission authentication;

2. The system includes 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 via VR controllers;

4. Supports users in

5. The system uses a realistic 3D scene for six-degree-of-freedom interactive operations with VR controllers, allowing users to navigate via controller operation;

6. The system supports text and voice prompts for operations.

Technical Approach:

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