Development of electrical control system fault knowledge base and modeling inference

A fault knowledge base management platform which uses the method of ADO.NET and directed graph is presented in this paper in order to deal with prognosis health management for electrical control system. At first, knowledge base is designed according to structure and function of the system, with hierarchical framework is taken into consideration to represent the relationship of electrical apparatus within a system, the fault topology model is derived based on directed graph with object oriented programming is proposed as design rules, Separate design model is created to add, delete, check and update easily. Secondly, knowledge update and display is given with method of decision making is also discussed in the fault model. Finally, design of power supply system for aerospace is given as case example to show the application of the platform.
