6. AI-Powered Alarm & Alert System

AI ensures accurate and timely alerts by:

✔ Reducing False Alarms: AI differentiates between normal variations and actual faults.
✔ Severity-Based Alerts: AI assigns priority levels based on the risk of failure.
✔ Predictive Alarms: Instead of reacting to failures, AI warns days or weeks in advance.
✔ Real-Time Notifications: Sends alerts via SMS, email, dashboard, or mobile apps.

💡 Example: AI in a steel factory detects overheating in a rolling mill, triggering an automated shutdown alert to prevent damage.

7. How AI Uses Historical Data for Predictive Insights

A. Benefits of Using Historical Data

• Identifies Recurring Failure Patterns: AI learns from past failures to detect future risks.
• Predicts Remaining Useful Life (RUL): AI estimates when equipment will need servicing.
• Improves Maintenance Planning: AI schedules maintenance only when necessary, reducing downtime.
• Reduces Costs: Avoids unnecessary part replacements and labor expenses.

B. Historical Data Analysis Workflow

1️⃣ Data Aggregation: AI collects years of sensor data.
2️⃣ Failure Pattern Recognition: AI detects trends in past breakdowns.
3️⃣ Predictive Model Training: AI refines models using historical cases.
4️⃣ Continuous Learning: AI improves accuracy with every new dataset.

💡 Example: AI analyzes 5 years of failure data from industrial compressors to predict the likelihood of overheating 3 weeks before it happens.
