Applied RCM^2 Algorithms Based on Statistical Methods

International Journal of Automation and computing 2007年第2期4卷 109-116页

作者： Fausto Pedro García Márquez Diego J. Pedregal etsi Industriales Universidad de Castilla-La ManchaCampus Universitario s/n 13071 Ciudad RealSpain

The main purpose of this paper is to implement a system capable of detecting faults in railway point mechanisms. This is achieved by developing an algorithm that takes advantage of three empirical criteria simultaneously capable of detecting faults from records of measurements of force against time. The system is dynamic in several respects： the base reference data is computed using all the curves free from faults as they are encountered in the experimental data; the algorithm that uses the three criteria simultaneously may be applied in on-line situations as each new data point becomes available; and recursive algorithms are applied to filter noise from the raw data in an automatic way. Encouraging results are found in practice when the system is applied to a number of experiments carried out by an industrial sponsor.
