Objective: Develop and deploy an AI-driven predictive maintenance system to minimize downtime and optimize the maintenance schedule of critical manufacturing equipment for Digital Solutions of Chillicothe. The goal was to harness the power of machine learning to predict equipment failures before they occur, thereby reducing unexpected downtime and maintenance costs.
Challenges Overcome: The most significant challenge was integrating the AI-driven predictive system with the existing legacy equipment, which was not originally designed to support IoT sensors and real-time data analysis. Additionally, collecting and processing large volumes of sensor data in real-time required careful consideration of network bandwidth and storage capacity. Another challenge was training the machine learning model to accurately predict failures based on historical data and real-time inputs.
System Design and Deployment: Led the design and deployment of the predictive maintenance system by first retrofitting the manufacturing equipment with IoT sensors capable of monitoring various parameters such as vibration, temperature, and pressure. Data from these sensors was streamed in real-time using the MQTT protocol to a central server running on Linux, where it was processed and stored in a PostgreSQL database. Developed and trained a machine learning model using TensorFlow and Keras to analyze the data and predict potential failures. Docker was used to containerize the AI application, ensuring it could be easily deployed and scaled across multiple machines. Grafana was implemented for real-time data visualization and monitoring.
Results: The predictive maintenance system successfully reduced unexpected equipment downtime by 60% and cut maintenance costs by 30%. The AI model achieved high accuracy in predicting equipment failures, allowing the maintenance team to perform timely interventions before any critical issues arose. The system also provided valuable insights into the equipment’s operational efficiency, enabling further optimization of the manufacturing process.
This project is a unique example of how AI and IoT technologies can be leveraged to bring about significant operational improvements in a traditional manufacturing environment. By combining advanced machine learning algorithms with real-time sensor data, the project delivered a solution that not only improved equipment reliability but also provided actionable insights that could be used for ongoing process optimization.
