To develop and apply statistical models for supporting PdM, it is always crucial to have as much as possible failure data, which is not easy to find in the companies’ databases. Furthermore, advancing and integrating different technologies in a single automatic and digitised smart PdM system is a challenge that requires close collaboration between research and industry players.
The Predictive Cognitive Maintenance Decision Support System (PreCoM) enables its users to detect damages, estimate damage severity, predict damage development, follow up, optimize maintenance (for reducing unnecessary stoppages) and get recommendations (on what, why, where, how and when to perform maintenance). PreCoM is a cloud-based smart PdM system using vibration as a condition monitoring parameter. Some accelerometers for measuring vibration (of both rotating and nonrotating components), as well as other sensors (i.e. for temperature), have been installed in machines’ significant components (i.e. components whose failures either expensive or dangerous). Over 20 hardware and software modules (common to all considered and equivalent use cases) are integrated into a single automatic and digitised system that gathers, stores, processes and securely sends data, providing recommendations necessary for planning and optimizing maintenance and manufacturing schedules. The PreCoM system includes loops and sub-systems for data acquisition, data/sensor quality control, predictive algorithm, scheduling algorithm, follow up tool, self-healing ability for specific problems, and end-user information interface.
