广州地铁3号线北延段西门子列车与国产牵引列车速度诊断逻辑分析

Speed Control Logic Analysis of Domestic Traction Trains and Siemens Trains in Northern-extension Section of Guangzhou Metro Line 3

针对西门子地铁车辆出现的列车速度信号异常故障,对广州地铁3号线西门子列车速度诊断逻辑进行研究和分析,并通过对比分析国产牵引列车网络控制系统的速度信号诊断逻辑,提出西门子列车速度诊断逻辑加入生命信号的优化方案,以提高列车运营的安全性。

Aim at the problem of abnormal speed signal in Siemens metro train, the speed diagnosis logic of Siemens train was analyzed and compared with domestic traction train＇s in Guangzhou metro line 3. Then, an optimized diagnosis logic scheme was proposed of adding the life signals for Siemens train to improve operation safety.
