| Abstract: | By monitoring and assessment the state of secondary equipment, the system information associated and fault feature extraction are used to warn the hidden fault. On the basis of the system state assessment, considering the cost of maintenance and system reliability can optimize maintenance strategy. The application failure warning system can effectively improve system reliability, reduce accident probability, reduce maintenance costs, and provide good power protection for the safety of the high-speed train punctuality run. |
