城市轨道交通全自动运行线路车辆基地的安全防护关键技术及应用

Key Technologies and Application of Safety Protection in Urban Rail Transit FAO Line Vehicle Depots

[目的]现阶段城市轨道交通全自动运行线路车辆基地的安全防护能力与全自动驾驶技术匹配度不高,未能最大限度发挥全自动运行技术在智能运维中的优势,需结合运营场景来分析安全防护的关键技术。[方法]通过总结城市轨道交通全自动运行系统的运营场景分类,并基于车辆基地的安全防护需求,梳理出相应的安全防护关键技术。[结果及结论]车辆基地的安全防护需求为断送电防护、区域防护、入侵报警防护和综合调度显示。相应的安全防护关键技术为自动断送电技术、库区整体防护技术、作业区域防护技术、区域防入侵技术、列车接近报警技术和综合调度显示技术。结合成都、深圳和无锡等城市的全自动运行线路车辆基地应用实例,探讨安全防护方面存在的不足,并提出加快智能安全防护技术的深入研发和应用推广建议。

[Objective]Nowadays,the safety protection capability of urban rail transit FAO(fully automatic operation)line vehicle depots is not well matched with the level of fully automatic driving technology,which is limiting the ability to maximize the advantages of FAO technology in intelligent operation-maintenance.Therefore,there is a need to analyze the key technologies for safety protection in accordance with the operation scenarios.[Method]By categorizing the operation scenarios of urban rail transit FAO systems and based on the safety protection requirements of the vehicle depots,relevant key safety protection technologies are sorted.[Result&Conclusion]The safety protection requirements of the vehicle depots include power interruption/connection protection,zone protection,intrusion alarm protection,and comprehensive scheduling display.Corresponding key security protection technologies involve automatic power interruption/connection technology,overall depot protection technology,operational zone protection technology,area intrusion prevention technology,train proximity alarm technology,and comprehensive scheduling display technology.By examining the application cases of FAO line vehicle depots in cities such as Chengdu,Shenzhen,and Wuxi,the shortcomings in safety protection are discussed,and recommendations are proposed to accelerate the in-depth research and application of intelligent safety protection technologies.
