Actors:

• Mining Equipment Operator: Individual responsible for operating and monitoring mining machinery.

• Maintenance Technician: Professional tasked with maintaining and troubleshooting mining equipment.

• Operations Manager: Supervisor overseeing mining processes and ensuring operational efficiency.

​

System:

Advanced Human-Machine Interface (HMI): A user-friendly interface integrated into mining machinery, facilitating seamless interaction between operators and the system.

 

Preconditions:

• Mining machinery is powered on and connected to the HMI system.

• Operators and technicians have received training on utilizing the HMI features.

​

Main Success Scenario:

1. The Mining Equipment Operator logs into the HMI system using secure credentials.

2. The operator selects the specific mining operation (e.g., drilling, hauling) from a predefined list on the HMI.

3. The HMI system automatically adjusts machine settings to optimize performance for the selected operation, minimizing manual intervention.

4. The operator initiates the mining process via the HMI interface.

5. The HMI provides real-time feedback on machine performance, including metrics such as speed, load, and any detected anomalies.

6. Upon completion, the operator logs out of the HMI system.

​

Extensions:

 

Alternative Flow – Manual Adjustment:

• If the desired operation parameters are not listed, the operator can manually input custom settings into the HMI.

• The system validates the input and prompts for confirmation before applying settings.

​

Exception Flow – System Alert:

• If the HMI detects a malfunction (e.g., equipment overheating), it triggers an alert.

• The Maintenance Technician receives a notification detailing the issue.

• The technician accesses the HMI to diagnose the problem, following guided troubleshooting steps provided by the system.

• After resolving the issue, the technician logs the maintenance activity within the HMI.

 

Postconditions:

• The mining operation is completed efficiently, with optimized machine performance and minimal downtime.

• All operational data is logged within the HMI system for future analysis and reporting.

​

Notes:

• The HMI system supports multi-user collaboration, allowing simultaneous access by operators, technicians, and managers.

• Integrated version control ensures that any changes to machine settings are tracked, maintaining a history of adjustments.

• Edge connectivity enables real-time data access and contextualization, providing actionable insights to enhance operational efficiency.

​

This use case illustrates how an advanced HMI system streamlines mining operations, enhances flexibility, and supports a user-friendly interface, addressing challenges such as frequent operation changes and varying operator skill levels.
