摘要
通过对二次设备的状态进行监测、评估,利用系统的信息关联和隐藏故障的特征提取对二次设备的隐藏故障进行预警。在系统状态评估的基础上,综合考虑维修成本和系统可靠性对维修策略进行优化。应用故障预警系统,可以有效地提高系统运行可靠性,减少事故概率,降低维修成本,为高速列车的安全正点运行提供良好的动力保障。
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.
