🛠️ The Future of Maintenance: Predictive Maintenance (PdM) with IoT
Predictive Maintenance (PdM) with Internet of Things (IoT) technology is a shift in mindset from reactive maintenance or preventive maintenance to predicting when a machine will break down so that maintenance can be carried out with the greatest possible accuracy.
💡 Main content: Working and investing in PdM with IoT
1. Machine condition monitoring with IoT sensors
Principle: Installing smart sensors (IoT Sensors) on important machines or equipment to continuously collect real-time data.
Data type:
Vibration: Used to check the condition of bearings, shafts and balance of machinery.
Temperature: Indicates excessive heat, which may be caused by friction or electrical malfunction.
Acoustic: Detects unusual sounds that indicate looseness or wear.
Current/Voltage: Check the operation of the motor or electrical system.
Benefits: This data is the pulse of the machine, allowing you to know its current condition and deterioration trends before a catastrophic failure occurs.
2. Data Analytics and Forecasting
Data Entry: The collected data is sent over the network to the cloud platform or server.
Analysis: Use Machine Learning (ML) and Artificial Intelligence (AI) techniques to analyze large amounts of data (Big Data) to:
Modeling: Define data patterns that indicate "normal" and "abnormal" conditions.
Failure Prediction: When real-time data deviates from normal patterns, the system warns that failure is likely to occur in the coming days or weeks.
Action: Maintenance teams can plan repairs, prepare spare parts, and perform repairs at pre-determined times (Planned Maintenance) before the actual machine breaks down.
3. Return on Investment (ROI): How to invest to get value and truly reduce downtime.
Investing in PdM is a strategic investment that generates high returns through cost reduction and production efficiency enhancement:
| Key Benefits (ROI Generator) | Description and results obtained |
| Reduce unexpected downtime | Predictive maintenance allows for a transition from unplanned downtime to planned downtime, which takes less time and has minimal impact on production (reducing downtime). |
| Extend the life of your machinery | Only repairing necessary parts at the right time reduces collateral damage and extends the life of the asset. |
| Reduce maintenance costs | Save on spare parts and labor costs by replacing parts when they are nearly broken, rather than replacing them on an unnecessary schedule (reduce over-maintenance ). |
| Increase production efficiency | When machines are operating at optimal conditions at all times and there are fewer production stops, the overall plant's overall equipment effectiveness (OEE) increases. |
💰 Investment strategies for maximum value
Start with Critical Assets: Select sensors for the machines that are most critical to production or those with the highest downtime costs to see rapid returns.
Choosing the right technology: Choose an IoT system that can connect to existing machinery (Legacy Systems) and has an easy-to-use and scalable data analytics platform.
People Development: Train your team to understand data insights and quickly translate them into actionable decisions.
IoT-enabled PdM is not just a technology, but a paradigm shift in asset management in the Industry 4.0 era, making maintenance truly smarter, more accurate, and more efficient.
