摘要
由于国内某地铁A号线已运营10 a以上,部分系统设备(如车载信号系统)严重老化,为避免对系统的正常运营造成影响,本文从RAMS表现值和设备故障趋势2个方面,采用基于数据的定量评估方法,对运营设备进行状态评估,以确定设备运行状态的发展趋势,并提出设备维保及改造更新的建议。研究结果表明:通过使用科学的RAMS管理方法,应用于城市轨道交通信号系统安全评估,可以为运营方的维护维修和改造更新提供决策依据。
The metro line A has been operated over 10 years,some system equipment(such as cab signal system)has been seriously aging.In order to avoid serious impact on the normal operation of the system,two aspects of the PAMS performance value and equipment failure trend based on quantitative evaluation method of data are analyzed to assess status of operating equipment,determine the development trend of the equipment operation state,and put forward maintenance and modification suggestions for the equipment.The result shows that using scientific RAMS management method applied to the safety assessment of urban rail transit signal system can provide decision-making basis for the maintenance and renovation of the operators.
