广州地铁4号线轨旁ATP故障应对策略研究

Coping Strategies against Track Side ATP Fault on Guangzhou Metro Line 4

轨旁ATP(列车自动保护)故障后,联锁区内的列车将全部自动紧急制动,列车采用降级模式运行,这会对正常运营产生较大影响。结合广州地铁4号线新造及石碁联锁区轨旁ATP故障实例,对比分析了故障现象及故障影响。阐述了轨旁ATP故障后的应对策略,通过确定关键列车、落实盯控关键列车、实施载客越站方案等策略应对故障,以最大限度降低故障对行车的影响。

When a track side ATP fault happens,all the trains in the interlocking area will take emergency breaking and run in degraded mode,that greatly threatens the normal operation.Based on the track side ATP fault on Guangzhou metro Line 4,the fault phenomenon and effects are comparatively analyzed.Then,the coping strategies against track side ATP fault are described,including traffic organization control link,skip schem and so on,to minimize the impact of track side ATP fault on train operation.
