VR Practical Assessment System for Underground Belt Conveyor Maintenance Workers

The VR practical assessment system for underground belt conveyor maintenance workers is a system that simulates maintenance work on underground belt conveyors through virtual reality technology. This system allows maintenance workers to perform practical operations in a virtual environment,

to enhance their skills and abilities.

This system uses devices such as VR headsets and controllers to immerse maintenance workers in the working environment of underground belt conveyors. They can perform maintenance tasks by operating virtual equipment, including inspecting

equipment status, diagnosing issues, and repairing faults. The system evaluates and provides feedback based on the maintenance workers' operations and performance to assess their skill levels.

This system offers several advantages. First, it provides a safe and risk-free practice environment where maintenance workers can perform practical operations in a virtual setting without causing any damage to real equipment. Second, it offers

an authentic and realistic experience, enabling maintenance workers to better understand and master the working principles and operational techniques of underground belt conveyors. Additionally, the system can record and analyze the operational data of maintenance workers for subsequent

training and improvements.

In summary, the VR practical assessment system for underground belt conveyor maintenance workers is an innovative training and assessment tool that enhances the skills and abilities of maintenance workers, improving the efficiency and quality of maintenance work.

System Features:

1. User login 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 using VR controllers;

4. Supports user navigation in the system through controller operations;

5. The system provides text and voice prompts for operations;

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

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 spraying and dust during operations.
