An open architecture for enabling CBM/PHM capabilities in ground vehicles

This paper describes a comprehensive, open and extensible architecture for a Ground Vehicle Health and Usage Monitoring System (GV-HUMS) that enables both Condition Based Maintenance (CBM) and Prognostics and Health Management (PHM) in vehicles. The on-board software provides near real time diagnostic and prognostic analysis in addition to gathering sensor data for off-board data mining. The CBM and PHM capabilities are provided as services and can be incrementally refined and expanded over time as the system collects more data without requiring an on-board software refresh in the system. The off-board software component allows for efficient data collection, data management, enables data mining, development and refinement of PHM and CBM capabilities and efficient collection of maintenance and fault data. The GV-HUMS system is modular and can be easily adapted to provide diagnostic and prognostic analysis for other vehicles on ground, water or air. This paper will provide a high level overview of the architecture, the incremental design approach, and current status of the system.
