PHM system is a multi-layers, multi-disciplines, high-coupled complex system and hard to be designed and verified as a whole, so there are no mature tools and methods for PHM design and verification. Design and verification of aircraft PHM system is researched from data-driven viewpoint. Four methods are used:1)System Modeling Language(SysML) could be used for the design of PHM system under Data-Driven Viewpoint; 2)Event-based method could convert the monitored system’s behavior to some states which will utilize resource of PHM system adequately so as to reduce the local resource pressure;3)Model-based reasoning method is introduced and system’s state model is implemented. 4)Eventually, a multi-thread method and a heterogeneous energy-coupled method are used to define a PHM simulation framework under which develops a simulation environment and verifies mentioned methods, and some test cases of power distributing system are developed for reasoning. The result of research shows that methods mentioned above are valid and could be used for construction of PHM system architecture completely and resource-balanced.
