Research on intelligent circuitry board detection and diagnosis method based on functional model

In order to settle the issue of difficulty in intelligent circuitry board detection and meet the requirement of board-level detection and maintenance in the equipment,this paper propose a embedded and interactive detection and diagnosis method for intelligent circuitry board based on functional model.General test model is built,and collective test idea and concrete detection technology and method are researched.The design concept and method of the test software are presented in detail,and SVM algorithm is employed to carry through failure determination.Finally it conducts simulation.The experiment has shown that the method can conduct effective detection for intelligent circuitry board and gives guidance to intelligent circuitry board detection.
