The design of the prognostics and health management system for special vehicle

With the rapid development of sensor technology on vehicles, more and more vehicles are checked from artificial detection to auto monitoring. A great number of real-time data acquired from sensors provides important foundation for PHM application on vehicles. Aiming at the special mining vehicle, it proposes the solution for real-time monitoring, fault diagnosis and health management based on the PHM theory. First, a kind of application service architecture is designed to describe how to implement the special mining vehicle PHM system and meet the needs of fault diagnosis and health management. Second, it describes each service module of the PHM platform system in detail, including inner functions and interaction. Third, it studies and proposes the models and methods of the various service modules, which can be used to implement the goals of the monitoring, diagnosis and health management from the view of the vehicle parameters. Finally, the Special Vehicle PHM System is developed based on the proposed models and methods, which is being successfully used in SanJiang Aerospace Group. The practical application result shows the proposed the design of PHM system can provides the service of fault diagnosis and health management for the special mining vehicles, which has great value for PHM implementation and promotion in the field of vehicles.
