Abstract
With the fast development of Chinese high speed railway, the demand for the maintenance of railway equipment has increased rapidly. This paper studies an intelligent diagnosis method for high-speed railway turnout based on the support vector machine. We focus on the study about the methods of generating the feature vector and propose a rule-based method that utilizes the experts' experience knowledge. By experimenting on the current curve collected on the real turnouts, we compare the advantages of different feature vector generation methods and demonstrate that our rule-based method performs best in the fault diagnosis. This work realizes the purpose of identifying the fault curves by computer automatically and can save a lot of manpower and resources. It provides a basis for the intelligent fault diagnosis of turnouts.
