Abstract: Signaling Equipment Predictive Maintenance Information System was used to implement data mining for maintenance information of subsystems in signalling system, combine with reliability, availability, and maintenanceability analysis result, set predictive maintenance strategy, define fault information collection template, provide free software WEKA-based predictive maintenance method, use the method software integrity development, build models of classifiers, cluster and association. This method was helpful to shorten development period as well as reduce software cost effectively.
