研究北京地铁10号线列车乘客信息系统故障成因及设备标准化准入机制，对提升运营服务质量有重要作用，将其作为智慧地铁建设试点，具有研究价值。采用折线图，对2016年10号线列车乘客信息系统的故障率进行分析；采用可靠性分析法，对故障模式、影响及危害性进行分析。依据分析结果，指出系统中重点故障排查困难以及缺乏设备准入制度的问题，提出优化检修周期、标准化设备准入的解决举措，并根据改进前后的故障对比分析，进行应用效果研究。研究结果表明，对车载乘客信息系统进行规范化管理，可以有效减少故障发生，提高检修效率。

In the investigation of the causes of faults in the passenger information system of the Beijing Metro Line 10 train, the standardized access mechanism of equipment has been found to have an important role in improving the quality of operational services. This study serves as a pilot for smart subway construction; hence, it has research value. A line chart is utilized to analyze the failure rate of the passenger information system of Line 10 trains in 2016. The reliability analysis method was employed to analyze the failure mode, influence, and safety. The analysis results indicated the difficulty of troubleshooting major faults in the system and the lack of an equipment access system. Based on the analysis, solutions for optimizing the maintenance cycle and standardizing equipment access were proposed. A comparative analysis of the faults before and after improvements were introduced was implemented. The research results show that the standardized management of the passenger information system can effectively minimize the occurrence of faults and improve maintenance efficiency.
