摘要
广州地铁 1号线信号系统具有列车运行自动调整功能 (ATR)。在系统实际应用过程中 ,ATR功能出现一些异常情况 ,表现出系统的自动调整功能失效。通过分析ATR系统的功能原理 ,确认了原系统ATR功能设计上存在的缺陷 ,提出了改进ATR功能的两种方案。其中 ,当设置列车通行时 ,把ATR发送给列车自动运行系统 (ATO)的运行时间先减去约 12 .6 4s这一方案已被采纳 ,并经过在实际信号系统中的验证 ,达到了预期的效果。
ATR (Automatic Train Regulation) was adopted in the signaling system of Guangzhou Metro Line 1. Some abnormal situation was observed while the ATR system was applied to the site.It is clear that ATR lost its efficacy.This analysis proves that there are limitations in the original function design of ATR.The author makes two schemes for the improvement of the function of ART,and one is tested in the real signaling system and has proved its function satisfactory in the amendment design.
