How XMPro iBOS Modules Work Together To Create This Predictive Maintenance Solution
XMPro Data Stream Designer
XMPRO’s Data Stream Designer lets you visually design the data flow and orchestration for your real-time applications. Our drag & drop connectors make it easy to bring in real-time data from a variety of sources, add contextual data from systems like EAM, apply native and third-party analytics and initiate actions based on events in your data.
Figure 1. Wind Turbine Condition Monitoring Data Stream
This renewable condition monitoring data stream for a wind turbine begins by reading all records from various data sources, including an OPC UA server. The data is then joined and contextualized with sensor data to provide a comprehensive view. Calculated metrics, such as oil levels, are derived from the sensor data. The processed data is broadcasted to multiple endpoints for further analysis. A failure recommendation rule is applied to identify potential issues, and the data is rounded and filtered specifically for wind turbines.
Figure 2. Wind Turbine Predictive Maintenance Data Stream
This wind turbine predictive maintenance data stream collects and processes various data inputs to predict turbine failures and optimize maintenance. The flow begins with collecting wind speed and direction, temperature, vibration, and sensor health data from different sources such as historians, OPC devices, and Azure IoT Hub. These inputs are normalized and joined with contextual data from SAP and Azure Digital Twin, which provides turbine make, model, location, and sensor context. The combined data undergoes transformations to convert types for calculations and merges with additional operational and health data. The data is then used to calculate turbine performance metrics and broadcast results to different predictive models. A binary classification model filters turbines likely to fail, followed by a regression model to estimate the remaining useful life (RUL). Anomalies and RUL are further analyzed, and recommendations are generated. The data is updated to Azure Digital Twin and ADX for continuous monitoring and maintenance actions, ensuring proactive and efficient wind turbine management.
Recommendation Manager
XMPRO Recommendations are advanced event alerts that combine alerts, actions, and monitoring. You can create recommendations based on business rules and AI logic to recommend the best next actions to take when a certain event happens. You can also monitor the actions against the outcomes they create to continuously improve your decision-making.
Figure 1. Erosion Prediction Recommendation
This recommendation for wind turbine MMWT003 identifies an erosion prediction greater than 4. The event data provided includes gearbox oil level (low), rotor specific temperature (11), reading number (2414652), timestamp (Dec 8, 2023, 11:13 AM), rotor temperature (34.73578261199211), and wind speed (14.43500123658916). Users can add notes, assign the recommendation, share it, and create a work request with special instructions for maintenance. The system tracks whether the recommendation solved the problem and provides options to mark it as a false positive or resolved. This setup ensures timely response to potential erosion issues, optimizing turbine performance and longevity through proactive maintenance actions.
