Predictive maintenance (PdM) leverages machine learning models to predict equipment failures before they happen, helping organizations minimize unplanned downtime, reduce maintenance costs, and extend the life of their assets.
Predictive Maintenance Models Supported by Rayven.io
Rayven.io supports multiple predictive maintenance techniques that address different asset types and operational environments. These include machine learning and statistical models designed for accuracy, scalability, and real-time integration.
1. Vibration Analysis
Monitors vibration patterns to detect early mechanical faults.
2. Survival Analysis
Estimates time-to-failure based on operating history and conditions.
3. XGBoost Analysis
Uses decision-tree-based modeling to predict complex failure patterns across multiple variables.
4. Pandas Data Profiling
Analyzes data quality and structure to support model readiness.
How Predictive Maintenance Works in Rayven.io
Predictive maintenance models are integrated into Rayven workflows using the platform’s drag-and-drop builder and real-time processing engine.
Setup Steps
To implement predictive maintenance in Rayven.io:
Step 1: Ingest Data
-
Use input connectors to pull live or historical data from IoT sensors, SCADA systems, PLCs, or external databases.
-
Common inputs include vibration data, usage hours, temperature, and environmental metrics.
Step 2: Profile and Prepare Data
-
Use Pandas Data Profiling to explore the structure and health of your dataset.
-
Apply Preprocessing actions to filter noise, normalize inputs, and extract important features (e.g., rolling averages, deltas).
Step 3: Select a Model
-
Choose the most appropriate PdM model:
-
Vibration Analysis for pattern deviations in rotating equipment.
-
Survival Analysis for predicting time-to-failure.
-
XGBoost Analysis for advanced, multi-variable modeling.
-
Step 4: Train the Model
-
Use the Machine Learning Node to train your selected model on labeled historical data.
-
For Survival and XGBoost models, define training parameters and split data into training/testing sets.
Step 5: Integrate in Workflow
-
Add the Run Model action inside the workflow to apply predictions in real time.
-
Connect the output to action nodes, alerts, or dashboard updates.
Step 6: Visualize and Monitor
-
Create dashboards that display:
-
Predicted failure risk
-
Remaining useful life (RUL)
-
Vibration anomalies or confidence scores
-
-
Use gauges, line charts, and tables to provide real-time status and historical comparisons.
Step 7: Respond to Predictions
-
Configure Rayven to trigger:
-
Maintenance requests
-
Escalations
-
Equipment shutdowns or performance adjustments
-
Summary
Rayven.io’s predictive maintenance toolkit includes:
-
Vibration Analysis for early mechanical fault detection
-
Survival Analysis for failure time prediction
-
XGBoost Analysis for high-accuracy, multi-variable insights
-
Pandas Data Profiling for data validation and quality checks
These tools work together to deliver predictive insights, reduce risk, and maximize uptime across industries such as manufacturing, energy, logistics, and infrastructure.
Q&A
Q: Which model should I use for rotating machinery?
A: Use Vibration Analysis to detect faults like imbalance, misalignment, or wear.
Q: How do I estimate when an asset is likely to fail?
A: Use Survival Analysis to model the likelihood of failure over time.
Q: What’s the advantage of XGBoost in predictive maintenance?
A: It provides accurate predictions and reveals the most important variables contributing to failure.
Q: How do I prepare my data before training a model?
A: Use Pandas Data Profiling and Rayven's Preprocessing tools to ensure clean, structured inputs.
Q: Can these models run in real time?
A: Yes. Once trained, models can be embedded in workflows and applied to live data streams.
Q: Can I automate maintenance actions?
A: Yes. When a failure is predicted, workflows can trigger alerts, service tickets, or even system adjustments.
Q: Should I retrain models regularly?
A: Retrain models as your systems or data patterns change. You can schedule retraining in workflows or trigger it based on performance metrics.
