Jiang Ping-yu · Modern Machinery · 2008
According to the characteristic of facilities group prognostics and health management systems,a layered PHM functional model is put forward in term of facility,workstation,facilities group and enterprise,the information relationship and requirements relationship are given at different layers or different function modules.Firstly,a layered PHM platform framework is established based on WEB Service and SOA technology.Secondly,based on time stamp technology,the data synchronization method is studied in an interoperation model based on XML.Thirdly,the collaborating problems between different functional component nodes are solved.Further more,a facilities degradation trend forecasting is established through logistic regression and support vector regression technology.Finally,a prototype of PHM software is developed to demonstrate the flexibility of above mentioned methods and technologies.
