国内首条自主化全自动运行地铁燕房线6月份调试

原标题:国内首条自主化全自动运行地铁燕房线5月底实现全线长轨通

央视记者近日从北京市重大项目办获悉,国内第一条自主化全自动运行地铁线路燕房线于5月25日实现全线长轨通,并计划于6月份开始全线动车调试,为年底通车奠定了坚实的基础。全自动运行系统是城市轨道交通自动化的最高等级,燕房线全自动运行系统整体技术已经达到国际领先水平。

燕房线(苏庄至燕化)全长16.6公里,共设9座车站(分别是燕化站、老城区北站、饶乐府站、顾八路站、阎富路站、星城站、阎村站、大紫草坞站和阎村北站),在阎村北站与房山线换乘。这条拥有最高自动化运行等级的地铁线路,初期最高运行时速可达80公里,共4辆编组,最大载客量为1262人。燕房线开通后将方便房山西部地区和燕化地区市民出行,进一步加强燕房组团、良乡组团与中心城区的交通联系,提升沿线地区人民群众的生活品质,对于带动北京南城燕山地区和房山地区的发展具有十分重大而深远的意义。

燕房线是自主化全自动技术在国内的第一次应用。全自动运行系统(Fully Automatic Operation, 简称FAO )是基于现代计算机、通信、控制和系统集成等技术实现列车运行全过程自动化的新一代城市轨道交通系统。列车从“唤醒”,准备启动运行开始,出发前进行31项设备自检。自检合格后,列车自动从车库内发车,进入正线运行,到站停车,开关车门,离站发车,运行中可以对整个运行各环节实现实时检测、实时应对。结束正线运行后,回到车场库内停车,列车会自动“洗澡”,然后设备断电,全部过程都不需要人工介入,均能通过设备控制自动实现。全自动运行系统免除了人工繁琐的日常检查、清洗作业,列车能够精准控制停车时间,解决了列车正线运行自动化程度低的问题。

据北京市重大项目办相关负责人介绍,全自动运行系统能够进一步提升城市轨道交通运行系统的安全与效率,可进一步提高系统可靠性、安全性、可用性、可维护性;提升系统应急处置水平;提升系统自动化水平,降低劳动强度,是衡量城市轨道交通系统功能和性能先进水平的标尺。

由于燕房线是国内第一次自主化全自动技术的应用,其安全性也是记者最关心的问题,燕房线相关负责人对此进行了详细说明。据介绍,全自动运行系统并非“无人驾驶”那么简单,它是一个庞大、精准的运行体系,具有可靠的车载全自动运行控制技术,列车自动休眠唤醒自动化技术,车辆障碍物及脱轨监测,列车控制及诊断系统,低压供电系统远程监控及重投,走行部安全监测和故障诊断等全自动运行的综合关键技术。

“全自动运行系统不依赖驾驶员的个人主观判断,遇紧急情况时会根据实际发生的情况,第一时间由系统自动作出“应对决策”,有效缩短了反应时间。同时,在全自动运行列车的运行过程中,运营控制中心会时刻监控列车的运行状况。遇到紧急情况时,运营控制中心能够及时与乘客进行紧急对讲。同时,烟火报警信息和视频的联动控制确保运营控制中心能够对列车状态实现实时安全监控。乘客可以放心乘坐。”燕房线相关负责人说。

燕房线全自动运行系统目前已通过由北京市科委组织的专家验收,其整体技术已达国际领先水平,并被国家发改委批准成为国家战略性新兴产业示范工程。下一步,北京市还将在开展的3、12、17、19、新机场线等新一轮北京轨道交通线路建设中推广应用全自动运行系统技术。
